Abstract

The invention discloses an adjustable general thoracic surgery chest opener which comprises fixing mechanisms used for being clamped on the outer side of the thoracic cavity, the fixing mechanisms are provided with chest opening mechanisms used for adjusting the chest opening size, the number of the fixing mechanisms is two, and a connecting rod is arranged between the chest opening mechanisms. A supporting mechanism used for limiting the chest is arranged on the connecting rod. A screw rod of the fixing mechanism rotates to push a suction cup to be adsorbed on the body, the whole body is fixed, and the stability in the using process is guaranteed; by adjusting the pressure of hydraulic oil on the two sides of a piston head in a first cavity of the thoracotomy mechanism, the piston head can conveniently push a sliding block to move relatively, the distance position of thoracotomy limiting plates on a connecting rod can be conveniently fixed, meanwhile, by adjusting the position of a sliding ring of the supporting mechanism on the connecting rod, the distance between the limiting plates can be conveniently adjusted, and the thoracotomy effect is improved. And the air cushion in the U-shaped opening is convenient for limiting and supporting the chest, so that the overall practicability is improved.

Description

technical field

[0001] The invention relates to the field of medical 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 chest opener is in use, adjust the movable arm left and right to increase the distance between the movable arm and the fixed arm, open the chest cavity, and play the role of opening the chest. Only relying on the contact with the chest cavity to fix the phase position of the two, The stability is poor; and the position of the thoracotomy needs to be fixed ma...
