Clip applying mechanism and clip applying apparatus thereof

Abstract

A clip applying mechanism and a clip applying apparatus thereof are provided. The clip applying mechanism includes a tube body, a main shaft, a clip-cartridge assembly, a clip-pushing assembly and a firing assembly; and further includes: a main-shaft connecting member, connected with the main shaft; a firing connecting member, connected with the firing assembly; an engagement mechanism, arranged between the main-shaft connecting member and the firing connecting member. The engagement mechanism, the firing connecting member, the main-shaft connecting member and the firing assembly are configured such that: in a case where the clip is fired, the main-shaft connecting member drives the firing connecting member to move in a direction facing away from the head end of the tube body through the engagement mechanism, and the firing connecting member drives the firing assembly to move in a same direction, so that the end effector is partially opened.
