Adjustable thoracotomy device for general thoracic surgery

Abstract

The invention discloses an adjustable thoracotomy device for general thoracic surgery. The adjustable thoracotomy device comprises connecting frames and positioning connecting pieces, wherein the tenpositioning connecting pieces are arranged, and the two connecting frames are arranged; the two connecting frames are symmetrically distributed left and right, the front ends and the rear ends of thetwo connecting frames are fixedly connected with sliding frames, and the four sliding frames are arranged; the four sliding frames are distributed in a completely symmetric mode, an expanding and contracting frame is movably connected between every two adjacent sliding frames in the front-back direction, and the expanding and contracting frames and the sliding frames are fixedly connected togetherthrough the positioning connecting pieces; and each of the two connecting frames is movably connected with one set of thoracotomy mechanisms, and the thoracotomy mechanisms and the connecting framesare fixedly connected together through the positioning connecting pieces. According to the adjustable thoracotomy device for general thoracic surgery, the two connecting frames are opened leftwards and rightwards by pulling the two expanding and contracting frames forwards and backwards, so that the two sets of thoracotomy mechanisms which are symmetrical leftward and rightward are opened leftwards and rightwards, then the thoracotomy effect is achieved, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of general thoracic surgery instruments, in particular to an adjustable chest opener for general thoracic surgery. Background technique [0002] A thoracotomy is a tool commonly used in general thoracic surgery. Its function is to stretch the ribs to a certain extent so as to facilitate the establishment of surgical access. The traditional thoracotomy has a relatively simple structure and its shape is similar to a vernier caliper. , consisting of a fixed arm, a movable arm, and a slideway, wherein the movable arm and the fixed arm are used to spread the ribs. When the traditional thoracotomy is in use, the movable arm is adjusted left and right, so that the distance between the movable arm and the fixed arm increases, and the chest cavity is opened to play the role of thoracotomy; during the operation, the surgeon stands on the left and right sides of the patient. side, and the movable arm can only move lef...

AI Technical Summary

Problems solved by technology

When the traditional thoracotomy is in use, the movable arm is adjusted left and right, so that the distance between the movable arm and the fixed arm increases, and the chest cavity is opened to play the role of thoracotomy; during the operation, the surgeon stands on the left and right sides of the patient. side, and the movable arm can only move left and right relative to the fixed arm, so it is not convenient to further adjust the opening of the thoracotomy during the operation; at the same time, the thoracotomy opens the chest as a whole, and the shape of the opening is Rectangular, the shape of the opening cannot be changed, and for the local area that needs to be further opened, it cannot be further opened in a targeted manner, which is inconvenient to use
