Adjustable chest opener for thoracic surgery

Abstract

The invention discloses an adjustable chest opener for thoracic surgery, relates to the technical field of medical apparatuses and instruments, and solves the problem that an existing chest opener cannot adjust the opening form and angle during use, and the surgical effect is affected. Theadjustable chest opener includes a mounting seat; the right side of the mounting seat is rotationally connected with a group of chest opening operation pieces; two groups of chest opening swing connecting rods are hinged to the front part of the mounting seat; a group of chest-opening flat-opening swinging pieces are hinged between the two groups of chest-opening swinging connecting rods on the same side; the rights side of the chest-opening flat-opening swing pieces are rotationally connected with a set of angle adjusting operation parts. According to the adjustable chest opener, parallel distraction can be achieved, meanwhile, the mounting angle of the chest opening swing rod can be adjusted, the opening angle and the openingform can be adjusted, the opening requirements under different operations are met, the adaptability is high, meanwhile, the chest opening jaw is easy to install and lock, the working efficiency can be greatly improved, the structure is simple, and cost is low.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable chest opener for thoracic surgery. Background technique [0002] In the process of thoracic surgery, thoracotomy is often encountered. The so-called thoracotomy refers to incision between the two ribs, and then slowly stretched with a chest opener, every few minutes to stretch one or two centimeters , operate through the stretched space.

Problems solved by technology

[0005] The object of the present invention is to provide a kind of adjustable thoracotomy for thoracic surgery, to solve the problem that the existing thoracotomy proposed in the above background technology is divided into two types, one is a flat opening type, and the other is a scissor type. , in use, the flat opening type can only be opened flat, and the scissors type swings to unfold. In the operation, due to the different forms and angles of the opening required for different surgical sites, the existing two types cannot be used for the opening form. and angle adjustment, affecting the effect of surgery
