Problems solved by technology

The former, although the cavity is satisfied, the pressurized CO 2 It may bring a series of complications: such as hypercapnia, subcutaneous mediastinal emphysema, air embolism, etc., and the process of cavity construction is time-consuming and traumatic; the latter requires instrumental traction, so the incision cannot be concealed and minimal. At the same time, because the existence of traction instruments affects the operating space of surgical instruments, it is even more regrettable that the cavity construction is unsatisfactory and lacks stability and flexibility.
Both have advantages and disadvantages, but neither is a perfect solution

Abstract

The invention relates to a device capable of being pulled by magnetic force to movably build a cavity and suitable for neck endoscopic surgery. The device is characterized in that the cavity building device is composed of a magnetic force device (1) arranged on the surface of the skin (2) and a support arm arranged below the layer of the skin (2), and the magnetic force device (1) arranged on the surface of the skin (2) attracts the support arm arranged below the layer of the skin (2) to move outwards to build the surgical cavity; the support arm is formed by movably connecting an upper layer support arm body (3) and a lower layer support arm body (6) through a rivet (4); the support arm is made of materials capable of being attracted by magnetic force. The device has the advantages that a small incision is formed in a relatively hidden part of the neck, the dual purposes of a surgery approach and postoperative drainage are achieved, and the effect of beautifying is achieved; the purpose of minimally invasive surgery is achieved; surgical wounds are reduced; the selection part of the surgical incision can have a large degree of freedom.

Description

technical field [0001] The invention relates to a device suitable for cervical endoscopic surgery for creating a cavity through magnetic traction. Background technique [0002] At present, the incidence of benign and malignant thyroid tumors is relatively high, and they are more common in women, many of whom are young or socially active. Surgery is the only way to treat these diseases. For the aesthetic effect after surgery, endoscopic or endoscopic-assisted thyroid surgery As a result, the necessary condition for endoscopic surgery is to establish a sufficient and stable cavity, but the neck lacks natural passages and potential cavities, which need to be artificially created. Currently, there are two methods: one is to fill the cavity with CO 2 Cavity building, the second is instrument traction cavity building. The former, although the cavity is satisfied, the pressurized CO 2 It may bring a series of complications: such as hypercapnia, subcutaneous mediastinal emphysema,...
