Abstract

A linear suturing and cutting device, comprising an upper jaw and a lower jaw capable of being closed or opened relative to each other; said upper jaw includes an anvil; said lower jaw includes a staple cartridge frame, said staple cartridge frame is detachably provided with a staple cartridge, said staple cartridge is arranged with cartridge holes inside which run throughout said staple cartridge to its working surface, and staple pushers correspondingly disposed inside said cartridge holes and being capable of sliding relative to said cartridge holes, said staple cartridge frame is slidably provided with a firing piece inside, said firing piece is configured with a wedge-shape staple pushing member capable of driving said staple pushers to slide in said cartridge holes, said cartridge holes are configured to be inclined towards the distal end of said staple cartridge. In this way, the direction of force received by the staple pushers is identical with the extending direction of cartridge holes during the staple pushers being pushed in the cartridge holes, thus the staple pushers will not get too large friction from the inner wall of cartridge holes and then can be pushed more smoothly, which reduces the difficulty of operation.
