摘要：
A medical anastomosis device (100), comprising a firing assembly (50), a staple anvil (30), a staple anvil assembly (34), and a staple cartridge assembly (32)； the firing assembly (50) comprises a staple cartridge push rod (54) provided with a stop pin (542) thereon； the staple anvil (30) is provided with a safety block (38) therein capable of coordinating with the stop pin (542)； the safety block (38) is provided with a clamping groove (384) thereon； when the anastomosis device (100) is in an initial status, the safety block (38) and the stop pin (542) do not contact each other； when the anastomosis device (100) is in a firing status, the movement of the safety block (38) is restricted, and the clamping groove (384) is located on a movement route from the distal end of the medical anastomosis device (100) to the proximal end； and when the anastomosis device (100) returns to the initial status after being fired, the stop pin (542) is clamped in the clamping groove (384), and the safety block (38) limits the stop pin (542) in the direction from the proximal end of the medical anastomosis device (100) to the distal end. The three status jointly compose the complete firing process of the staple cartridge assembly (32), preventing a second firing of the staple cartridge push rod (54) to ensure operation safety.
