The instrument includes: a suturing mechanism including an anvil assembly and a mounting part for mounting a staple cartridge assembly, in which the staple cartridge assembly includes a staple cartridge for accommodating staples, and the anvil assembly includes an anvil matched with the staple cartridge; a staple pushing assembly, configured to push the staples so that the staples are sequentially fired; a transmission assembly, configured for driving the staple cartridge assembly to move relative to the anvil assembly and driving the staple pushing assembly to move to push the staples; and a drive assembly, connected to the transmission assembly and configured for driving the transmission assembly to move.

Abstract: A medical apparatus, including a clamp, a work head and a handle. The work head is connected to the clamp and the handle and includes: a casing, a firing forcing member, a firing rod connected to the firing forcing member, a receiving cavity arranged at a side of the firing rod, and a clip-cartridge assembly; the clip-cartridge assembly being arranged in the receiving cavity and configured for delivering ligation clips to the clamp. An inner cavity communicating with the receiving cavity is formed in the casing. The firing rod is connected to the firing forcing member and the clamp respectively, and the firing forcing member drives the firing rod to move so as to open or close the clamp. The medical apparatus further includes a limiting member, which is configured for preventing at least one of the clip-cartridge assembly and/or a driving assembly from exceeding a stroke range.
