摘要：
A linear suturing and cutting device (100), comprising an upper forceps holder (101) and a lower forceps holder (102) that can be closed and opened mutually. The upper forceps holder (101) comprises a nail anvil (10). The lower forceps holder (102) comprises a nail cartridge rack (103), and the nail cartridge rack (103) is detachably provided with a nail cartridge (20). The inside of the nail cartridge (20) is provided with a nail cartridge hole (21) which runs through the surface of the nail cartridge (20) and a nail pushing sheet (40) which is arranged inside the nail cartridge hole (21) and can slide relative to the nail cartridge hole (21). The inside of the nail cartridge rack (103) is further slidably provided with a trigger sheet (30), and the trigger sheet (30) is provided with a wedge-shaped nail pushing unit (31) which can drive the nail pushing sheet (40) to slide inside the nail cartridge hole (21). The nail cartridge hole (21) is inclined towards the far end of the nail cartridge (20). In this way, when the nail pushing sheet (40) inside the nail cartridge hole (21) is pushed, the stress direction of the nail pushing sheet (40) is identical to the extension direction of the nail cartridge hole (21), and relatively large friction force between the nail pushing sheet (40) and the inner wall of the nail cartridge hole (21) can be avoided, so that the nail pushing sheet (40) can be pushed more smoothly, and the surgical difficulty can be reduced.L'invention concerne un dispositif de suture et de découpe linéaires (100), comprenant un organe de retenue de pince supérieur (101) et un organe de retenue de pince inférieur (102) qui peuvent être fermés et ouverts mutuellement.
