Skin soft tissue stretching and closing equipment

Abstract

The invention discloses skin soft tissue stretching and closing equipment. The skin soft tissue stretching and closing equipment comprises a pressure reducing device which is fixed to the edge skin ofa first side of a wound surface through a flexible wire and is elongated, and an occlusion device, wherein the flexible wire is in a U-shape, and the U-shaped bottom is abutted against the side wallof the pressure reducing device; the occlusion device is fixed on the edge skin of a second side opposite to the first side, of the wound surface through the flexible wire, is connected to the pressure reducing device through the flexible wire, and comprises a first clamping piece and a second clamping piece which can pivot relative to each other around a pivot axis; and the first clamping piece and the second clamping piece are used for clamping a section of length on the two U-shaped extending sections of the flexible wire so as to control the length of the flexible wire between the pressurereducing device and the occlusion device. The skin soft tissue stretching and closing equipment is easy and convenient to use and wide in application range.

Description

technical field [0001] The present disclosure generally relates to the field of wound repair, tissue reconstruction. More specifically, the present disclosure relates to a skin and soft tissue stretch closure device. Background technique [0002] Skin and soft tissue injuries may be the most common traumas faced by human beings in their lives, from various injuries in the wild hunting for a living in ancient times, to various factory accidents and traffic traumas under the rapid development of modern society, and to various chronic diseases in modern society. For chronic skin wounds (diabetic foot, vascular ulcers, pressure sores, etc.), the repair of skin and soft tissue damage has always been the focus of clinical research. Wound debridement and suture is the earliest surgical treatment technology invented and applied in clinical practice. With the rapid development of medical technology in recent years, various sutures, medical glue, skin ordering machine, skin transplan...

AI Technical Summary

Problems solved by technology

With the rapid development of medical technology in recent years, various sutures, medical glue, skin ordering machine, skin transplantation, skin flap transplantation, etc. have been successfully used for wound closure. However, there is no ideal solution for wounds with large skin and soft tissue defects. At present, skin transplantation or skin flap transplantation is routinely used in clinical practice, which is not only complicated in operation and requires high operation skills, but also needs to obtain tissue from the donor site, which will cause secondary trauma. In addition, the newly transplanted skin or transferred skin Flap sensation is often poor, which can only meet the basic requirements of wound closure, but cannot meet the needs of functional restoration. Therefore, finding and exploring a more ideal wound repair method is an urgent problem to be solved clinically.

[0003] From the process of female pregnancy and childbirth, it is found that the skin, subcutaneous soft tissue, fascia and muscle can expand and regenerate under the condition of continuous tension. Subsequent studies have found that soft tissues such as skin have unique viscoelastic properties. Expansion and extension can occur under continuous tension and stress conditions. Based on this, various skin expanders and skin stretching techniques are applied to the expansion and regeneration of skin, which have certain advantages compared with traditional skin grafting and skin flap transplantation. Advantages, however, the skin expander in the body needs to be surgically implanted first, and then the slow expansion of the skin can be completed through 1-2 months of water injection, which not only takes a long time, but also has the risk of implant infection, so it is not suitable for use Repair closed wounds; skin stretching technology has become a research hotspot in recent years because of its simple operation and convenience. At present, the commercialized products for clinical application mainly come from European and American countries, which are mainly composed of skin attachment system, traction power system and tension maintenance. The system consists of three parts, the equipment structure is relatively complicated, and the cost is relatively expensive, and the skin attachment system is mostly realized by metal devices such as Kirschner wires, staples, or skin hooks, which not only causes serious damage to the skin, but also mainly fixes riveting In the dermis of the skin, in clinical application, only the stretching and expansion of a single tissue structure of the skin can be completed, and the synchronous expansion of the subcutaneous superficial fascia, deep fascia and muscle tissue cannot be achieved. It is applied to wounds with deep soft tissue defects There is a risk of insufficiency and subcutaneous cavities during closure. In addition, because of its complex structure and large space volume, it is limited to the actual use site in clinical practice. There are many defects, and the full-dimensional reconstruction of the ideal soft tissue structure cannot be realized
