Wound closure device

Abstract

The invention relates to a wound closure device, in particular to a wound closure device in the field of skin wound suture. The invention aims to provide a wound closure device comprising a window, apuller and a fixer, wherein the window comprises a window body wall, a window top wall and an opening / closing window arranged on the window top wall. The puller is arranged on both sides of the window; one end of the puller is connected with the fixer and the other end is connected with the window; and the fixer is provided with a fixed adhesive layer facing the bottom surface of the skin. The wound closure device of the invention enables the functional modules required for wound treatment to reliably, continuously and directly continue to act on the wound healing area, effectively avoiding the seepage fluid accumulation to cause the suture device to fall off, secondary wound infection, wound suture failure, wound malformation healing, and better wound physiological regeneration healing.

Description

technical field [0001] The invention relates to a wound closure, in particular to a wound closure in the field of skin wound suturing. Background technique [0002] In the field of human medical anatomy and tissue repair, skin tissue is the most basic and important barrier sealing structure inside and outside the human body. Skin tissue includes the epidermis, dermis, and subcutaneous layer of the skin. When this barrier is damaged by surgical cutting or trauma, it must be sutured through surgery, so that the free skin edge of the wound can restore the original layered alignment as soon as possible according to the original anatomical structure of the skin, and the original skin barrier structure can be restored through skin tissue regeneration. Physiological function. In order to promote the delamination and apposition of free wound skin margins, the precise apposition and smoothness of wound skin margins in the horizontal and vertical axes is particularly important for wo...

Problems solved by technology

However, the various closing devices currently available can only simply realize the function of closing and pulling the wound in the horizontal axis. The wound healing area located in the middle of the wound, complete or independent and undisturbed use of various functional treatment modules or units that play an important role in promoting wound healing: such as wound exudate absorption module, wound skin edge apposition reference module, wound hemostasis Module, wound antibacterial and antibacterial module, sensor module for collecting wound information, cell tissue regeneration module for promoting wound healing

Therefore, in the actual clinical application of various existing matching devices, the following disadvantages are inevitable: 1. Lack of independent, efficient and timely cleaning of wound bleeding and exudate modules, and a large number of exudate accumulations secondary to wound infection , Suture device falling off due to exudate accumulation, wound suture failure, delayed wound healing, wound non-healing

2. Lack of a continuous and effective vertical coercion mechanism or coaptation reference module, unable to ensure that the skin edge of the wound is cohesive and smooth in the vertical axis, unable to complete the precise coaptation of skin layers, and a large number of mishealed malunions (such as step malocclusion) occur. layer healing, pimple healing, poor scar body healing)

3. The wound healing area lacks effective wound hemostasis modules, wound antibacterial and antibacterial modules, tissue regeneration promotion modules and other continuous effects, or it is actually impossible to guarantee that the above modules are reliable and continue to directly act on the wound healing area, and their actual efficiency is extremely high. low or virtually absent

Difficult to achieve good physiological regenerative healing of wounds
