Round wound model device

Abstract

The invention relates to a round wound surface model device. The defects in the prior art include that large error exists between preparing models and practical demand; error exists during natural healing process with the wound surface; size of the wound surface is low in selectiveness and large in application limit; the preparation process is tedious and complicated and not strong in repeatability and low in standardization. The round wound surface model device is characterized by comprising a cylinder with diameter changed and jointed by two rectangle bodies. A horizontal telescopic shaft is arranged on the line of centers of the rectangle bodies, a rotating shaft penetrates the center of the horizontal telescopic shaft vertically, the top end of the rotating shaft protrudes out of the cylinder body and is provided with a handle, and a horizontal and flexible cutter shaft is arranged on the lower portion of the rotating shaft. The round wound surface model device is simple in structure and low in manufacturing process and experimental technique requirements, easy to operate and strong in repeatability, so that scientific research is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of burn surgery and plastic surgery, relates to the field of basic research on tissue damage and repair and supporting equipment, in particular to a circular wound model device. Background technique [0002] Since the emergence of biomedicine, tissue damage and repair has always been one of the most direct problems that clinical medical workers have to face. The skin on the body surface is the first line of defense that constitutes the immune barrier of the body. When the body surface tissue is damaged and a wound is formed, timely and complete wound repair is the key to preventing and avoiding further damage expansion. At the same time, with the development of society, various complex and refractory wounds continue to appear, which brings new challenges to traditional wound treatment measures. Therefore, wound repair is one of the most important and fundamental problems faced by the entire medical profess...

Problems solved by technology

However, the above-mentioned existing circular wound model preparation methods all have certain limitations. Therefore, finding and establishing a new type of simple and standardized circular wound model production method and device has become the endeavor of the majority of scientific researchers. direction

[0005] The current research has found that although the existing tools and methods can be used to realize the preparation of circular or approximately circular wound models, however, the above methods have the following disadvantages: ①The scalpel cutting process is poorly controllable and standardized, and the prepared model is consistent with There is a large error in actual needs; ②The hole punch has a large mechanical impact on the wound base and the wound edge, and there is a certain error with the natural healing process of the wound; the wound size has low selectivity, and the application limitations are large; ③Preparation The process is cumbersome and complicated, the stability of the prepared wound model is not good, the repeatability is not strong, and the degree of standardization is low
