Problems solved by technology

[0003] However, mitral valve surgery faces the same problem regardless of the incision approach: the mitral valve is deep and difficult to expose.
At present, the design concept of retractors in clinical application is only to realize the opening of the left atrium roof to expose the mitral valve, and it is impossible to make the mitral valve shallower, so as to facilitate the operation of the surgeon.

Abstract

The invention relates to a left atrial appendage retractor and an auxiliary assembly for mitral valve surgery. The left atrial appendage retractor includes a base, the base is rotatably connected withone end of a suspension arm structure, the suspension arm structure is formed by rotatably connecting multiple segments of suspension arms, and the angle between every two suspension arms can be adjusted; the portions between the corresponding suspension arm and the base and the portion between every two adjacent suspension arms can be locked by first locking pieces, the other end of the suspension arm structure is connected with a connector, the connector is coaxially connected with the corresponding suspension arm and can rotate around the axis of the corresponding suspension arm connectedwith the connector, and second locking pieces can be utilized for locking; the connector is connected to one end of a connecting rod, and the other end of the connecting rod is connected with a retractor structure. By means of the left atrial appendage retractor and the auxiliary assembly, the position of the mitral valve can be shallow in a surgical process, and surgical operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of surgical tools, in particular to a left atrial appendage retractor and an auxiliary component for mitral valve surgery. Background technique [0002] At present, cardiac mitral valve surgery has become a routine operation in cardiac surgery. The volume of operations is huge, and it is estimated that there are more than 50,000 cases nationwide every year. [0003] However, mitral valve surgery faces the same problem regardless of the incision approach: the mitral valve is deep and difficult to expose. At present, the design concepts of retractors used clinically all stay at the realization of opening the roof of the left atrium to expose the mitral valve, and cannot make the mitral valve shallow so as to facilitate the operation of the operator. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a retracto...
