Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically relates to a prone position surgical field exposure retractor. Background Technique

[0002] With the continuous progress of medicine, the continuous innovation of understanding, and the continuous improvement of surgical instruments, the development of modern medicine and the improvement of all surgical instruments are all towards the direction of facilitating the operation of surgeons, shortening the operation time, and clearly exposing the surgical area. During the operation of traditional hemorrhoid surgery, the patient usually needs to lie on the side, and an assistant pulls the anus upward and downward to expose the perianal tissues, clearly exposing the hemorrhoid tissue at the anus to facilitate the operation of the surgeon. When the hemorrhoids are small or there are few hemorrhoids, and the number of operating tables is small, the total operation time is short, and the assistant can still hold on. However, when encountering hemorrhoid surgery with more hemorrhoids, more operating tables, and greater surgical difficulty, the total operation time will increase significantly. With the increase in the number of perianal surgeries, the assistant who exposes the hemorrhoid tissue will obviously have sore hands, and the exposure of the surgical area will be unsatisfactory. When encountering the need for hemostasis or more difficult complex situations, due to the insufficient exposure of the surgical area, it will significantly increase the surgical difficulty and bring certain troubles to the surgeon and the affected limb.

[0003] In the prior art, during the operation, wide adhesive tape is often used for stretching and traction, and the part to be disinfected is pasted with an infusion patch, resulting in poor stability and low flexibility in applying to patients of different body types. Therefore, we propose a new type of prone position surgical field exposure retractor. Content of the Utility Model
