Special-purpose surgical knife tool component and technological process for human body colotomy

Abstract

The present invention provides a special-purpose surgical knife tool component and a technological process for human body colostomy; the knife tool component is characterized in that the knife tool component is composed of a skin flat-unfolding device, a titanium alloy cylinder, a titanium alloy subbase, a knife tool bar member and a rigid support; when operating, the human body skin flat-unfolding device unfolds flatly and tightens a abdomen laying operation region, then the titanium alloy cylinder cup dolly is bonded and fixed at the laying position for a human body abdomen operation wound, the knife tool bar member is covered on a circumference screw thread of the titanium alloy cylinder rotationally, finally the rigid support fixed on an operating table is connected with the titanium alloy cylinder through a rigid localization; here rotating the knife tool bar member, its cutting part excides the skin and the subcutaneous fat tissue along the circumference fringe of the titanium alloy cylinder subbase to reach a prescribed depth, fetching the rigid support and the knife tool bar member, pulling the titanium alloy cylinder upward and exciding the fat tissue of abdominal wall closed aponeurosis position by a conventional surgical knife, then lifting and pulling the incised columnar tissue, the contour forming operation of artificial anus is then over.

Description

technical field [0001] The invention relates to a special surgical tool assembly for human artificial anus plasty and a process method for human artificial anus plasty in the medical device industry. Background technique [0002] In the current domestic and international traditional operations of human artificial anus plastic surgery, due to the lack of special surgical knives and techniques, too much subcutaneous fat tissue is often removed, and the surgical wound is irregular, and a standardized cylindrical wound cannot be formed, resulting in subcutaneous fat. A dead space is formed between the tissue and the artificial anus, which is likely to cause postoperative infection, resulting in the failure of the artificial anus. Contents of the invention [0003] The present invention aims to provide a special surgical knife assembly for human artificial anus anoplasty and a process method for human anus anoplasty, so that the appearance of the artificial anus wound is cylind...
