Title:
SURGICAL INSTRUMENT FOR REPAIRING CARTILAGE TEAR
Document Type and Number:
WIPO Patent Application WO/2021/049746
Kind Code:
A3
Abstract:
A surgical instrument for repairing a cartilage tear, of the present invention, can simply and safely fix a first fixing piece (501) and a second fixing piece (502) to a torn cartilage through a very simple method for sequentially discharging the first fixing piece (501) and the second fixing piece (502) provided to be connected to suture threads (10) through a needle (411) at the tip of a push rod guide (410) while selectively moving a push rod (200) a predetermined width forward in multiple stages by means of an operation of pressing and lowering a push button (300), which is inserted into a button coupling hole (120) of an instrument body (100) so as to receive the elastic repulsive force of a spring (310), or releasing and lifting the pressed button. In addition, since the present invention definitively divides the operations of discharging the first fixing piece (501) and the second fixing piece (502), a safety pin (600) is inserted into the push button after an operator has discharged the first fixing piece (501) so that the push button (300) is not pressed unless the push button (300) is unlocked again, thereby preventing an erroneous operation in which the second fixing piece (502) is discharged to another position instead of the correct position by mistake.
