Abstract

The invention provides a coronary artery bypass grafting proximal anastomosis auxiliary apparatus adjusting mechanism. The coronary artery bypass grafting proximal anastomosis auxiliary apparatus adjusting mechanism includes a pipe wall clamp and a pipe wall clamp adjusting mechanism; the pipe wall clamp adjusting mechanism includes an adjusting cap and an adjusting rod; the adjusting rod is inserted into a pipe wall clamp body from the top face of the pipe wall clamp body and inclines backwards; the side wall of the periphery of the lower end of the adjusting rod meshes with the portion, placed inside the pipe wall clamp body, of a lower retaining ring clamp through a thread; the middle portion of the adjusting rod is an outward protrusion part which is eccentrically arranged at one sideof the axis of the adjusting lever, and in this way, when the outward protrusion part meshes with the rear end face the portion, placed inside the pipe wall clamp body, of an upper retaining ring clamp through the thread, the adjusting rod is separated from the lower retaining ring clamp; the portion, placed in the pipe wall clamp body, of the upper retaining ring clamp is an upward hunch-up arc,and the upper retaining ring clamp is hinged to the pipe wall clamp body through a rotation shaft; the adjusting rod includes a neck part penetrating through the top of the pipe wall clamp body, and the upper and lower ends of the neck part are clamped at the outer and inner sides of the top face of the pipe wall clamp body. The coronary artery bypass grafting proximal anastomosis auxiliary apparatus adjusting mechanism is simple in structure and easy to operate and improves the stability and safety of operation.

Description

technical field [0001] The invention relates to a proximal anastomotic auxiliary instrument for coronary artery bypass grafting. Background technique [0002] The invention patent with the patent number ZL201220301496.2 discloses a minimally invasive proximal anastomotic auxiliary device for coronary artery bypass grafting, which is mainly aimed at improving the simplicity of operation, reducing bleeding and protecting blood vessels, but it does not affect the vessel wall. The adjustment of the upper and lower buckle clips of the clip adopts independent adjustment parts to realize the position adjustment of the upper buckle clip and the lower buckle clip respectively, and the position adjustment of the lower buckle clip needs to be realized with the aid of the auxiliary operating lever, and the components appear Numerous and cumbersome operations, and the unavoidable phenomenon of unstable operation and falling of the auxiliary operating rod, it is easy to bring tension and ...
