AI Technical Summary

Technical Problem

Existing incision protectors are prone to shifting during multiple instrument operations, causing them to fall off the incision. Furthermore, the use of multiple instruments can pull on the skin around the incision, increasing the size of the surgical wound.

Method used

An incision protector was designed, comprising a retaining ring, a clamping mechanism, a fixing component, and a driving component. The clamping mechanism holds both ends of the incision, the fixing component adheres to the skin, and the driving component achieves stable fixation of the incision.

Benefits of technology

It improves the stability of the incision protector during surgery, prevents the incision from being stretched and enlarged, prevents the patient's wound from enlarging, is easy to use and detachable, facilitates replacement and prevents cross-infection.

Abstract

This invention provides a surgical incision protector for thoracoscopic surgery, comprising: a fixing ring, a clamping mechanism, a fixing component, a driving element, a diaphragm, and a cover ring. By inserting the diaphragm into the surgical incision, the fixing ring is positioned over the incision, and two sets of clamping mechanisms contact the skin on both sides of the incision ends. The fixing component contacts the skin surrounding the incision. The clamping mechanism is then driven to clamp both ends of the incision. During this process, the clamping mechanism, through the driving element, drives the fixing component to adhere to the skin around the incision, thereby securing the fixing ring to the incision. This improves the stability of the device on the incision, preventing it from detaching during surgery. Furthermore, by clamping both ends of the incision, it prevents the skin around the incision from being pulled during surgery, thus avoiding enlargement of the surgical wound and preventing further enlargement of the patient's surgical wound.
