Adjustable chest opener for general thoracic surgery

Abstract

The invention provides an adjustable chest opener for general thoracic surgery, which comprises a device body, the device body comprises a fixed transverse plate, a fixed longitudinal plate and a movable plate, a groove is formed in the middle of the fixed transverse plate, a partition plate for dividing the groove into an upper groove and a lower groove is arranged in the groove, a strip-shaped through hole is formed in the partition plate, and the movable plate is arranged in the groove. A containing cavity penetrating through the upper groove is formed in the inner side of the left end of the fixed transverse plate, the fixed longitudinal plate is fixedly connected to one end of the fixed transverse plate, and the movable plate is movably connected with the fixed transverse plate; the pushing assembly is movably connected to the interior of the containing cavity; the tensioning assembly is movably connected to the right end of the fixed transverse plate, and the tensioning assembly is movably connected to the movable plate; the number of the pusher dog assemblies is two, and the pusher dog assemblies are movably connected with the fixed longitudinal plate and the movable plate correspondingly; through cooperation of multiple assemblies, the force is uniform during thoracotomy, and the pusher dog rotates according to the angle of a wound.

Description

technical field [0001] The invention relates to the technical field of medical supplies, 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 spread the ribs. [0003] In thoracic surgery, it is necessary to use a thoracotomy to open the ribs, and then perform surgery on the internal organs. The traditional thoracotomy has cumbersome adjustment steps, uneven thoracotomy and large force required for thoracotomy, which is very easy to scratch the patient. Injury or some damage to the ribs, and the position and angle of the claws for thoracotomy a...

Problems solved by technology

[0003] In thoracic surgery, it is necessary to use a thoracotomy to open the ribs, and then perform surgery on the internal organs. The traditional thoracotomy has cumbersome adjustment steps, uneven thoracotomy and large force required for thoracotomy, which is very easy to scratch the patient. Injury or some damage to the ribs, and the position and angle of the claws for thoracotomy are fixed, and the angle of the device cannot be adjusted according to the actual situation of the patient, so that the force exerted by the claws on the patient's skin when fixing the incision is concentrated on a point or a small area within the range, causing secondary damage to the incision of the patient
