Title:
TISSUE SUTURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/007592
Kind Code:
A1
Abstract:
A tissue suturing system, comprising a first roller (1), a second roller (2), a first power device (3), a second power device (4), and a suture needle (5). The suture needle (5) is inserted between the first roller (1) and the second roller (2) parallel to an axis and is clamped by the two rollers, at least one of the two rollers actively rotates, and the two rollers apply force to the suture needle (5) through a clamping position of the suture needle (5). The first power device (3) provides a position where the first roller (1) and the second roller (2) are relatively close to each other to be parallel to the axis and clamp the suture needle (5). The second power device (4) provides a rotational power for the active rotation. The suture needle (5) is of a bent structure, is driven by the active rotation process to insert into and withdraw from tissue (6) in a bending direction, and always has an external exposed position for the two rollers to clamp. The tissue suturing system has changed the current modes of holding, adjusting, inserting, and withdrawing needle of the suture needle (5), which can effectively improve the efficiency of the suturing process, and the whole operation process is more accessible to many operators due to the reduction of difficulty.
