摘要：
A medical anastomose 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 anastomose device (100) is in an initial state, the safety block (38) and the stop pin (542) do not contact each other when the anastomose device (100) is in a firing state, the movement of the safety block (38) is restricted, and the clamping groove (384) is located on a movement path from the distal end of the medical anastomose device (100) to the proximal end and when the anastomose device (100) returns to the initial state after firing, 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 anastomose device (100) to the distal end. The three states 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.
