FLEXIBLE SURGICAL STAPLER AND STAPLE INSERTION DEVICE Inventors: Charles P. Chalekson David G. Matsuura Philip J. Simpson Nelson Siu RELATED APPLICATION DATA [0001] This application claims the priority benefit of U.S. Provisional Application Serial No.63/214,706, filed June 24, 2021, which is hereby incorporated in its entirety herein by reference. FIELD OF THE INVENTION [0002] The present invention relates to tissue approximation and fixation, and surgical staples and staple placement devices for surgery and the like. BACKGROUND OF THE INVENTION [0003] In human and veterinary surgery, closure of the surgical site can be quite challenging and influential upon the overall outcome of the procedure. For example, many open and laparoscopic surgeries involve closure across multiple layers, or “levels” of tissue. The manner in which this closure is performed can be critical to a successful outcome and prevention of complications. [0004] The most effective approaches to multi-level closure involve carefully crafted approximations involving a variety of fixation techniques and devices. They are often not performed to the full extent possible due to their: (1) intensive time requirement; (2) difficulty of using traditional sutures in certain tissue layers; and (3) limited options in terms of device alternatives to sutures. [0005] Securing and closing multiple layers can easily occupy 50% of surgical times in specialties such as plastic surgery and other specialties. [0006] Even when they are performed, they are susceptible to significant failure, as they often involve somewhat precarious arrangements. For example, a continuous running suture might cause an entire tissue plane to lose securement suffer from even a single point along its course fails. Certain tissue planes do not accept traditional needle and suture material well, such as fat, loose areolar tissue planes and muscle. There is significant desire to close these planes and to remove dead space, but upon suturing, the material tears through resulting in very poor ability to atraumatically and successfully reinforce these sites which can result in significant scarring. [0007] Closure issues are also seen in intradermal closure, which affects all surgical specialties. Dermis is the one layer that all surgeons close. As mentioned above, running suture potentially compromises the entire incision. Other closure device options are bulky, have a tendency to extrude from the body prematurely, and are imprecise. [0008] In contrast, discontinuous securement in which sections of tissue are connected but individually locked in place allow for discrete and differential tensioning. This allows the surgeon to set more accurate, exacting, and reliable points of closure across multiple levels of tissue. [0009] Multiple layer closure further decreases tension on all other closure locations, resulting in less dehiscence, better soft tissue support [with maintenance of tissue positioning], and better scar outcomes. In addition, it can mitigate seroma and fluid accumulation, reducing or eliminating the need for surgical drains. [0010] Surgical procedures can result in creation of a void around tissues that normally have direct contact and adherence with other tissues. The primary medical concern with respect to this void, also referred to as “dead space” is that fluid, or sometimes gas, can collect within this space. A seroma is the collection of fluid within this potential space. Seromas most often occur at a surgical site where tissue has been intentionally elevated. Friction between these elevated layers, trauma to the tissue or an inflammatory response to foreign bodies [such as implants or mesh] may result in further production of this undesirable fluid. [0011] Seromas can cause discomfort, damage surrounding tissue, compromise normal healing, create a substrate for infection, and cause troublesome aesthetic issues. [0012] One option to decrease the risk is the placement of surgical drains, which may be left in place anywhere from a few days to multiple weeks. They require significant maintenance, are painful, and are mostly, but not completely effective at draining any fluid moving into the space. Drains do not prevent the production of fluid. [0013] One option to close and remove dead space is the placement of internal quilting sutures at the time of surgery. This entails the closure of elevated tissue planes with a large number of meticulously placed sutures to close and obliterate dead space, preventing friction and establishing contact to minimize fluid production. In this spirit, post-surgical compression garments applied to stabilize the tissue to limit edema and fluid production. In addition, the surgeon may frequently place one or more drainage tubes at the site. [0014] Nonetheless, swelling and fluid can collect either immediately or in delayed fashion, even many weeks after surgery. This can result in additional comorbidity, medical cost, and procedures for the patient, even jeopardizing the procedure success itself. [0015] Procedures prone to seromas and for which drains are commonly used are numerous but are most frequently seen in both plastic surgery and general surgery. Surgeries that involve elevation and undermining of larger amounts of tissue tend to have higher risks toward seromas. [0016] Some examples include breast surgeries such as lumpectomies, mastectomies, reductions, abdominoplasties, body lift procedures, hernia repairs, lymph node removal, tumor resections, and manipulation of major organs. [0017] There are major costs and complications associated with post-surgical management of dead space and typically involve seromas, infection, and hematomas or other bleeding. Serious or long-term problems related to a seroma are regarded as infrequent but can be costly, time-consuming, and require additional surgery and treatment. [0018] However, there remains a need for efficient and effective tissue approximation in order to best reduce seroma formation, as well as to reduce or eliminate the need for draining. SUMMARY OF THE INVENTION [0019] The present invention includes a surgical staple adapted to be anchored into tissue, the suture comprising: (a) a flexible staple bridge of a flexible resorbable or other suture-like material; and (b) staple legs extending from the staple bridge and (c) one or more barbed anchor portion on the staple legs and shaped so as to resist the withdrawal from tissue once placed into tissue once the staple legs are inserted into tissue, the staple legs adapted to be moved from a relatively compressed state to a relatively expanded state, or from a relatively expanded state to a relatively compressed state. [0020] The present invention also includes a surgical staple comprising: (a) a solid first leg for anchoring in a first tissue portion, a solid second leg for anchoring in a second tissue portion, and an elastically deformable bridge monolithically formed with the first leg and the second leg; the solid first leg and the solid second leg each forming a divergent angle, such as a respective angles greater than 90 degrees with respective portions of the elastically deformable bridge, the elastically deformable bridge of sufficient elasticity so as to permit the first leg and the second leg to be urged from an angled position to a substantially parallel position or beyond; and (b) each of the solid first leg and the solid second leg having a terminal end each comprising a distally directing point, such that, the solid first leg and the solid second leg have been urged into the substantially parallel position, the distally directing points are directed substantially orthogonal to the elastically deformable bridge; and each the terminal end having interior lateral sides comprising a lateral barb directed distally and to an angle to the respective leg. [0021] The present invention further includes a surgical staple comprising: (a) a solid first leg for anchoring in a first tissue portion, a solid second leg for anchoring in a second tissue portion, and an elastically deformable bridge monolithically formed with the first leg and the second leg; the solid first leg and the solid second leg each forming a convergent angle forming respective angles less than 90 degrees with respective portions of the elastically deformable bridge, the elastically deformable bridge of sufficient elasticity so as to permit the first leg and the second leg to be urged from an angled position to a substantially parallel position; each of the solid first leg and the solid second leg having a terminal end each comprising a distally directing point, such that, the solid first leg and the solid second leg have been urged into the substantially parallel position, the distally directing points are directed substantially orthogonal to the elastically deformable bridge; and each the terminal end having interior lateral sides comprising a lateral barb directed distally and to an angle to the respective leg. [0022] The surgical staple of the present invention may be of any effective dimensions, but an average non-limiting range of dimensions (based on surgical application) are as follows: (a) the cross members or bridge portions of the staples may be in the range of from about 5 mm to about 10 mm wide with a cross section in the range of from about .5 mm (round or rectangular) to about 1.5 mm; (b) the length of the legs including the barbs may be in the range of from about 3 mm to about 8mm, and (c) the barb dimensions for the above range of staples and with varying shapes (length and width) may be in the range of from about 1 mm to about 4 mm. [0023] The straight, shaped, pre-compressed, and tensioned staples are shown in Figures 1 thru 68b, including those that are delivered under tension and which expand or contract after release. [0024] Also included are expandable arrows which can be actuated by applying tension to the suture after insertion in the tissue such as for use with the suture material in accordance with the use of the staples for tissue approximation. [0025] The present invention also includes arrangements to address the movement of tissue in response to the insertion of the straight and or pre-tensioned staples. [0026] The staples may be provided in stacked arrays such as through use of a frangible connection between adjacent staples, such as though any effective attachment means such as through the use of adhesives, co-molded structure, interferent structures or the like, so as to maintain the staple array within a cartridge structure. [0027] The present invention also includes a device with a handle to allow the staples to be stored unstressed and then tensioned by tracks or mechanisms in the handle prior to delivery or release to facilitate intended function. [0028] In one embodiment, each of the staples may have a plurality of barbs of sufficient number and length so as to resist the withdrawal once the staple is placed into a tissue. [0029] The device of the present invention includes staple insertion device comprising: (a) a handle portion; (b) substantially parallel insertion portions extending from said handle, said insertion portions each having an interior lateral channel, and each insertion portions having a terminal point; the insertion portions adapted to slidingly engage a flexible staple, whether a straight staple, or a flexible staple that is adapted either to have its legs compressed and expand upon release from the device, or to have its legs expanded and compressed and upon release from the device. [0030] The insertion portions may also be angled outward and may also be moveable between a relatively convergent position to a relatively divergent position. [0031] The present invention also includes method of tissue approximation or attachment that may be carried out for example by using the handle portion of the described device and staple delivery portion (such as the insertion needles with or without a slider of driver) to place a surgical staple of the present invention. [0032] This may be carried out such as may be described generally as using the handle portion with its sharp insertion portion for obtaining access to a tissue through its facing surface, in order to place a series of staples across or on either side of an incision or other tissue requiring approximation. [0033] The insertion needle portions extending from the handle portion are extracted from the tissue leaving the surgical staple imbedded within the tissue. [0034] In one variation, as the delivery portion may be served by a slider or driver that reciprocates within a channel and is retracted into the handle where it will engage with the staples in series and position the staple in a position to be deployed as the initial staple has been inserted and the device is moved to a subsequent location. [0035] As the delivery portion (pusher) is retracted into the handle portion, it may conceivably engage with another surgical staple and position it ready to be deployed as described above. This would allow device to repeat the operation as described above a plurality of times, thus becoming a “multi-shot” surgical staple placement device. [0036] Other variations to the invention include providing moving and pivoting needle insertion portion for facilitating tissue manipulation or approximation prior to delivery of the staple into the manipulated tissue.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0127] Figure 1 shows a lateral perspective view of a flexible surgical staple and staple insertion device in accordance with one embodiment of the invention. Figure 1 shows staple insertion device 1 comprising a handle portion 2 and insertion needle portions 3a and 3b having opposed channels 3c and 3d. Opposed channels 3c and 3d hold in sliding engagement flexible staple 4 by engaging staple legs 4a and 4b, while staple bridge portion 4c is held in a relatively compressed state such that the staple legs 4a and 4b are maintained aligned with respective insertion needle portions 3a and 3b. In this position the flexible staple is in a loaded compressed state so that it may be inserted into tissue at sufficient depth to approximate the tissue. Flexible staple legs 4a and 4b are provided with one or more outwardly directed barbs 4d and 4e that permit insertion while securing the flexible staple 4 in place in the tissue once the flexible staple 4 expands. [0128] Figure 2 shows a lateral perspective view of a flexible surgical staple and staple insertion device in accordance with one embodiment of the invention, and wherein like numerals refer to identified features. Figure 2 shows flexible staple 4 as it is partially released from insertion needle portions 3a and 3b, and showing the lateral expansion of staple legs 4a and 4b as they are slid from respective insertion needle portions 3a and 3b permitting staple bridge portion 4c to decompress toward its uncompressed state, as the staple insertion device 1 is withdrawn from the tissue to be approximated. [0129] Figure 3 shows a lateral exploded perspective view of a flexible surgical staple and staple insertion device in accordance with one embodiment of the invention. Figure 3 shows flexible staple 4 fully released from insertion needle portions 3a and 3b and showing the completed lateral expansion of staple legs 4a and 4b as staple bridge portion 4c is fully decompressed after having been inserted into tissue at sufficient depth to approximate the tissue. [0130] Figure 4 shows a detailed lateral perspective view of a flexible surgical staple and staple insertion device in accordance with another embodiment of the invention. Figure 4 shows staple insertion device 11 similar to staple insertion device 1 and comprising a handle portion 12 and angled insertion needle portions 13a and 13b having opposed channels 13c and 13d. The angled insertion needle portions 13a and 13b assist in facilitating tissue approximation during insertion. [0131] Opposed channels 13c and 13d hold in sliding engagement flexible staple 14 by engaging staple legs 14a and 14b, while staple bridge portion 14c is held in a relatively compressed state such that the staple legs 14a and 14b are maintained aligned with respective insertion needle portions 13a and 13b. In this position the flexible staple is in a loaded compressed state so that it may be inserted into tissue at sufficient depth to approximate the tissue. Flexible staple legs 14a and 14b are provided with one or more outwardly directed barbs 14d and 14e that permit insertion while securing the flexible staple 14 in place in the tissue once the flexible staple 14 expands. [0132] Figure 5 shows a detailed lateral perspective view of a flexible surgical staple and staple insertion device in accordance with the embodiment Figure 4, and wherein like numerals refer to identified features. Figure 5 shows flexible staple 14 as it is partially released from insertion needle portions 13a and 13b, and showing the lateral expansion of staple legs 14a and 14b as they are slid from respective insertion needle portions 13a and 13b permitting staple bridge portion 14c to decompress toward its uncompressed state, as the staple insertion device 11 is withdrawn from the tissue to be approximated. [0133] Figure 6 shows a lateral exploded perspective view of a flexible surgical staple and staple insertion device in accordance with the embodiment Figure 4, and wherein like numerals refer to identified features. Figure 6 shows flexible staple 14 fully released from insertion needle portions 13a and 13b and showing the completed lateral expansion of staple legs 14a and 14b as staple bridge portion 14c is fully decompressed after having been inserted into tissue at sufficient depth to approximate the tissue. [0134] Figure 7 shows a lateral perspective view of an assembled array of flexible surgical staple in accordance with one embodiment of the invention. Figure 7 shows surgical staple array 20 comprising a series of staples 21 each having staple legs 21a and 21b and staple bridge portion 21c. Flexible staple legs 21a and 21b are provided with one or more inwardly directed barbs 21d and 21e that permit insertion while securing the staple 21 in place in the tissue once the flexible staple 14 expands. The staple array 20 may be created by providing a frangible connection between adjacent staples, such as though any effective attachment means such as through the use of adhesives, co-molded structure, interferent structures or the like, so as to maintain the staple array within a cartridge structure or the like of a staple insertion device while permitting a staple driver to separate and drive each staple in series through hand force or equivalent actuator force.

Flexible staple legs 4a and 4b are provided with one or more outwardly directed barbs 4d and 4e that permit insertion while securing the flexible staple 4 in place in the tissue once the flexible staple 4 is permitted to expand once inserted into tissue. [0191] Figures 67a and 67b show respectively a frontal view and a lateral perspective view of a flexible surgical staple 4 in accordance with one embodiment of the invention as held compressed during insertion, while Figures 68a and 68b show lateral perspective views of a flexible surgical staple 4 (as released following insertion) in accordance with one embodiment of the invention, and wherein like numerals refer to identified features. [0192] It will be appreciated that the handle, insertion portion, the anchor delivery portion, and the anchors may be produced from any material appropriate to the intended use whether sterile or non-sterile (i.e., for uses other than surgery or treatment, such as taxidermy or post-mortem use), and with due regard to disposability where desired. For instance, the handle, insertion portion, and the anchor delivery portion may be produced from metal, such as medical grade aluminum, while the handle portion may be produced from metal or plastics commonly used in medical devices, typically disposable ones. [0193] The surgical staples, surgical staple placement devices and surgical staple placement and tissue approximation methods of the present invention may be applied to any surgical procedure that may include, benefit from or require tissue approximation or fixation, including without limitation procedures prone to seromas including various forms of plastic surgery, large tumor resections, and procedures involving repositioning of major organs. The most common types of surgery that result in seromas include breast procedures, abdominoplasty, body contouring and hernia repair. Other procedures where the present inventions may be advantageously applied include those where tissue approximation is required following the use of a trocar, such as procedures involving trocar placement through the abdomen during laparoscopic surgery. Still other procedures may be those involving tissue approximation associated with securing grafts and implants. In addition to the closure of dead space internally, there also exists a need for rapid and accurate closure of skin and dermis more superficially. The ability to prevent dehiscence of surgical incisions frequently relies upon meticulous repair of the dermal and subcuticular layer, which are the source of strength in surgical closure sites. [0194] There exists a need to be able to apply independent and accurate staple placement in rapid fashion within the dermis and/or subcuticular plane to facilitate quicker and more reliable tissue approximation and wound closure. [0195] The tissues that may be approximated through use of the subject surgical staples, suture placement devices, and suture placement and tissue approximation methods may include tissues of any type having two or more generally opposed or adjacent portions that may be advantageously drawn together to a desired position. [0196] It will be appreciated that the present invention may be applied to other fields for the tissue approximation, adjoining and fixture, such as in veterinary medicine, or providing embalming or taxidermy services, and the like. [0197] Figure 69 show expandable arrows which can be actuated by applying tension to the suture after insertion in the tissue such as for use with the suture material, such as suture 22, in accordance with the use of the staples for tissue approximation. [0198] The present invention also includes arrangements to address the movement of tissue in respond to the straight and pre-tensioned staples. [0199] Figures 70 – 72 are a series of views showing how a straight staple 90 may be inserted into tissue 23 such as through manual or tool manipulation manually or with a tool as is known in the art. These Figures show staple 90 having staple legs 90a and 90b and staple bridge portion 90c. Staple legs 90a and 90b are provided with one or more inwardly directed barbs 90d and 90e that permit insertion while securing the staple 90 in place in the tissue 23 that has been manually approximated. [0200] Progressive Figures 73 – 75 show a tapered self-approximating staple 100 having staple legs 100a and 100b and staple bridge portion 100c. Staple legs 100a and 100b are provided with one or more inwardly directed barbs 100d and 100e that permit insertion while securing the staple 100 in place in the tissue 23 that has been manually approximated. The taper of the staple legs 100a and 100b causes the tissue to approximate as the legs converge during insertion toward the staple bridge portion 100c. [0201] Progressive Figures 76 – 78 show a pre-tensioned surgical staple 110 which collapses when released from the handle thus causing the tissue 23 to approximate, as shown in this series of Figures. Staple 110 has staple legs 110a and 110b and staple bridge portion 110c. Staple legs 110a and 110b are provided with one or more inwardly directed barbs 110d and 110e that permit insertion while securing the staple 110 in place in the tissue 23 that has been manually approximated. Staple 110 is tensioned in the delivery device so as to collapse inward upon insertion and release from the insertion device into tissue 23. [0202] Figure 79a shows a surgical staple 120 having staple legs 120a and 120b and staple bridge portion 120c. Staple legs 120a and 120b are provided with one or more flexible outwardly directed barbs 120d and 120e that may be molded as part of respective staple legs 120a and 120b or be cut out post-molding. Outwardly directed barbs 120d and 120e are sufficiently flexible to flex in response to insertion into tissue, to permit insertion while securing the staple 120 in place in the tissue 23 that has been manually approximated. [0203] Figure 79b shows a surgical staple 130 having staple legs 130a and 130b and staple bridge portion 130c. Staple legs 130a and 130b are provided with one or more flexible inwardly directed barbs 130d and 130e that may be molded as part of respective staple legs 130a and 130b or be cut out post-molding. [0204] Figure 80a shows an elevation view of a surgical staple in accordance with one embodiment of the invention. Figure 80a shows a surgical staple 140 having staple legs 140a and 140b and staple bridge portion 140c. Staple legs 140a and 140b are provided with one or more flexible outwardly directed suture material lengths 140d and 140e that may be molded as part of respective staple legs 140a and 140b or be inserted as separate pieces as shown, post-molding. Outwardly directed suture material lengths 140d and 140e are sufficiently flexible to flex in response to insertion into tissue, to permit insertion while securing the staple 140 in place in the tissue 23 that has been manually approximated. The suture material lengths 140d and 140e may be of a bioabsorbable material, while the surgical staple 140 may be of a bioabsorbable material or otherwise of a rigid material. In the embodiment wherein the suture material lengths 140d and 140e is of a bioabsorbable material while the surgical staple 140 is of a rigid material requiring subsequent removal, the suture may dissolve post-insertion, permitting relatively easy removal of the rigid staple by a straight pulling action.
