Tissue stretching and closing instrument for wound surface repair

Abstract

The invention discloses a tissue stretching and closing instrument for wound surface repair. The tissue stretching and closing instrument comprises a stretching and closing device and a guide-in device, wherein the stretching and closing device comprises a titanium wire and a resistance-augmenting titanium pipe; the guide-in device comprises a handle and a guide pins; the guide pins include a guide pin A and a guide pin B; the guide pin A is matched with the resistance-augmenting titanium pipe for use and comprises a pin rod and a pinhead part, and the pin rod can be connected into an inner cavity of the resistance-augmenting titanium pipe in a sleeving manner; when the pin rod is connected into the inner cavity of the resistance-augmenting titanium pipe in a sleeving manner, one end of the resistance-augmenting titanium pipe is blocked by the pinhead part located at one end of the pin rod; and one ends, far from the pinhead part, of the guide pin A and the guide pin B are detachably and fixedly connected with the handle. According to the tissue stretching and closing instrument, the stretching and closing device can be guided into hierarchical tissues at different depths, and layer-by-layer stretching and closing are realized according to dissection levels of the tissues of a human body, so that the tissue stretching and closing instrument is accordant with physiological processes of the wound surface repair, and the comfort level and the wound surface repair speed of a patient are greatly increased.

Description

technical field [0001] The invention relates to a tissue stretching closure device for wound repair. Background technique [0002] Skin and soft tissue defects are common surgical problems in clinic. Commonly, for skin and soft tissue defects with low local wound skin tension and small area, direct suture is often used clinically; for skin defects with large local defects or large wound skin tension, direct suture is usually not used clinically, but suture is used. Other methods repair and reconstruct the wound. [0003] Skin stretching is to use external force to pull the normal skin on both sides of the wound to the center, and use skin viscoelasticity and mechanical stretching to generate "extra" skin through a linear load cycle, thereby closing the wound. It has the advantages of rapid wound closure, fewer complications, All skin organs and their corresponding functions are retained, and the operation is simple. The theoretical basis is that normal skin has the biolog...

Problems solved by technology

[0004] Existing skin stretchers only pull shallow or full layers, and the force is not accurate enough. Moreover, the device is located outside the skin, which will interfere with the patient's movement and bed rest, and the nursing and dressing changes are relatively troublesome.
