Abstract

The invention relates to a device for creating cavities under magnetic traction actions. The device is applicable to endoscopic neck surgery, and is characterized by comprising a magnetic device (1) and support arms; the magnetic device (1) is arranged on the surface of a skin (2), and the support arms are arranged below a layer of the skin (2) and can be attracted by the magnetic device (1) on the surface of the skin (2) to outwardly move, so that the surgical cavities can be created; the support arms include an upper-layer support arm (3) and a lower-layer support arm (6) which are movably connected with each other by a rivet (4); the support arms are made of materials capable of being magnetically attracted. The device has the advantages that only relatively concealed positions of the necks of patients need to be slightly incised, the device can be used for surgical approach and postoperative drainage, and beautifying effects can be realized; the purposes of minimally invasive surgery can be achieved; surgical trauma can be reduced; surgical incision can have high degrees of freedom of selected positions.

Description

technical field [0001] The invention relates to a device for building a cavity in endoscopic surgery. 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, air embolism, etc., and the process of cavit...
