Operative pull hook

Abstract

Disclosed is an operative pull hook which is conducive to reducing incision length, incision healing and various intraoperative observation operations. A main hook (1) is arranged at one end of a hook body, an auxiliary hook (4) is arranged at the other end of the hook body, a through groove (3) is formed in the middle of the hook body, length of the main hook is 65-120 mm, and a smoke guide tube (2) is adhered in an area, extending to a hook back, of the outer side of the main hook. One end, facing the tail end of the main hook, of the smoke guide tube is provided with an opening, and one end, facing the hook back, of the smoke guide tube is provided with an opening and is away from a plane, in which the hook bottom is positioned. The operative pull hook is suitable for being used to build an operative working cavity.

Description

technical field [0001] The invention relates to surgical instruments, in particular to retractors for surgical cavity construction. Background technique [0002] At present, the incidence of thyroid cancer is increasing year by year. With the advancement of CT and ultrasound examinations, preoperative examinations are increasingly perfect for disease assessment, and are more sensitive to the detection of lymph node metastasis in the lateral neck region, even those in the parapharynx, which were considered rare in the past. Lymph node metastases can also be detected earlier, and the implementation of corresponding lateral neck lymph node dissection has also been continuously improved. [0003] From the perspective of surgical incision approach, most medical units can now replace the traditional L-shaped incision with the lower neck incision to complete the related operations of lateral neck lymph node dissection, which greatly reduces the size of the incision, but at the same...

Problems solved by technology

[0005] The present invention aims to solve the problem that the surgical retractors used in the prior art to establish surgical operating chambers cannot meet the needs of neck surgery, especially small neck incision surgery to obtain a deep operating space, and the smoke generated in the surgical area is difficult to get rid of, which affects the surgeon during the operation. For the problems of carrying out various observation operations, a surgical retractor of the present invention is provided. This surgical retractor is suitable for a small incision in the neck to obtain a deep operating space, and can eliminate the smoke generated in the surgical area, which is conducive to being pulled.
