Thoracic surgery draw hook device convenient to use

Abstract

The invention relates to the field of medical instruments, in particular to a thoracic surgery draw hook device convenient to use. The thoracic surgery draw hook device convenient to use comprises twosets of fixing rods, wherein the left ends of the two sets of fixing rods are fixedly connected with each other through a corresponding rectangular frame, the right ends of the two sets of fixing rods are fixedly connected with each other through a corresponding rectangular frame, installation frames are arranged on the lower sides of both the rectangular fixing frames, rack grooves are formed inopposite sides of both sets of fixing rods, draw hook components are arranged between two sets of fixing rods on the left and right sides, the draw hook components comprise limiting parts slidingly connected between the two sets of fixing rods, arc rods which are fixedly connected with the sides, away from the rectangular fixing frames, of the limiting parts through two sets of connection parts symmetrically arranged, a plurality of sets of hooks which are connected with the arc rods through sleeve rings in a hung mode, limiting strips which are symmetrically arranged in the limiting parts front and rear in a clearance fit mode, and rotating rods, and first sliding rings which slidingly match the fixing rods are arranged at both the front and rear ends of each limiting part. According tothe thoracic surgery draw hook device convenient to use, the hooks can be adjusted to pull the thoracic cavity to expose a surgery spot only by rotating the rotating rods and moving the rotating rods,so that operation is simple, and thus the working difficulty is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an easy-to-use drag hook device for thoracic surgery. Background technique [0002] In the process of thoracic surgery, it is necessary to incise the skin, subcutaneous tissue, and muscle layer, and enter the thoracic cavity through the narrow intercostal space to complete the operation, while the intercostal space needs to be stretched and stretched manually. This operation is not only very troublesome, time-consuming, and labor-intensive resources, and it is easy to hinder the normal operation of the operation, which increases the labor intensity and work difficulty for the medical staff. [0003] At present, the Chinese patent No. "201620891331.3" discloses a new type of thoracic surgery retractor, which includes two fixed rods, one end of which is connected by a fixed cross bar, and the other end is connected by a movable cross bar, with a rectangular groove in the middle; ...
