Abstract

The invention discloses a surgical instrument. The surgical instrument includes a handle assembly, a shaft assembly, an end effector and a nail cartridge assembly. The shaft assembly is connected to the handle assembly, the end effector is disposed at one end of the shaft assembly, and the nail cartridge assembly is mounted in the end effector. The nail cartridge assembly includes a nail cartridgebody and a nail cartridge protective cover, and the nail cartridge protective cover is detachably connected to the nail cartridge body. A barrier portion is disposed on the nail cartridge protectivecover and / or the nail cartridge body. After the nail cartridge protective cover is connected to the nail cartridge body, the barrier portion is used for forming space between the nail cartridge body and a baffle plate. According to the surgical instrument, suturing nails can be well sealed in the nail cartridge body before being fired, and the suturing nails are prevented from being separated fromthe nail cartridge body during storage and transportation due to extrusion or external force; and at the same time, the surgical instrument further solves the problem that the nail cartridge protective cover is detached from the nail cartridge assembly together with part of the suturing nails when the nail cartridge protective cover is removed.
