Adjustable thoracotomy device for general thoracic surgery

Abstract

The invention discloses an adjustable thoracotomy device for a general thoracic surgery. The adjustable thoracotomy device structurally comprises a fixed point arm, a locking buckle, a sliding rod, an inductor and a distraction arm, wherein the fixed point arm is electrically connected with the inductor through the locking buckle, one end of the fixed point arm is arranged above the sliding rod in a sliding fit mode, the distraction arm is installed at the other end of the fixed point arm, the distraction arm comprises a connecting rod, a spacing layer, a supporting block, a clamping hook assembly and a running-in belt, the connecting rod is welded to the bent position of the distraction arm, the bottom of the connecting rod is fixedly connected with the running-in belt, the supporting block is inserted into the running-in belt, the arc-shaped inner side of the supporting block is connected with the spacing layer in an embedded mode, the clamping hook assembly is installed on the spacing layer, a dilation device and an ejector sliding structure are arranged in the hook assembly, the dilation device is matched with a supporting plate through the ejector sliding structure, when liquid on a rib lubricates the tip end of the distraction arm, the liquid can make contact with the supporting plate, opening and closing operation is conducted from the middle to the two sides through the dilation device and the ejector sliding structure, the contact area of the tip end is indirectly enlarged, and the downward sliding speed is changed.

Description

technical field [0001] The invention relates to the field of thoracic surgery medical equipment, in particular to an adjustable chest opener for general thoracic surgery. Background technique [0002] A thoracotomy is a tool commonly used in thoracic surgery. Its function is to stretch the ribs to a certain extent to facilitate the establishment of surgical access. The traditional thoracotomy has a relatively simple structure and is similar in shape to a vernier caliper. It consists of a fixed arm, a movable arm and a slideway, wherein the movable arm and the fixed arm are used to stretch the ribs. The tip of the stretching arm of the existing adjustable chest opener for general thoracic surgery is a smooth structure. When stretching the ribs , once the liquid on the ribs lubricates the tip of the spreader arm, under the action of partial gravity, it will accelerate the sliding speed at the opening of the affected area, and finally hit the protruding ribs or muscle tissue at...

When stretching the ribs , once the liquid on the ribs lubricates the tip of the spreader arm, under the action of partial gravity, it will accelerate the sliding speed at the opening of the affected area, and finally hit the protruding ribs or muscle tissue at the bottom, causing damage to body tissue and ribs. Increased risk of equipment damage or broken ribs
