elastic skin stretcher

Abstract

The invention discloses an elastic skin distractor. The elastic skin distractor comprises a syringe needle and an elastic band, and also comprises a housing, an avoidance cavity, a wire avoidance duct, an ultraviolet germicidal lamp, a fixed shaft, a wheel disc, a spring, a gear clamping plate, a handle, a cover plate, an avoidance hole, a fixed sleeve and a screw. The elastic skin distractor is ingenious in structure has powerful functions. By adoption of the device, firstly, the elastic band can be tightened by simple operation according to the need, then, the continuous tightening effect can be achieved by a built-in spring mechanism, finally, the contractive effect of a patient wound can be increased, complications such as wound disunion or wound dehiscence which are caused by too large tension of the wound can be prevented, and the postoperative rehabilitation effect of the patient is ensured, thereby facilitating clinical promotion and application.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an elastic skin stretcher. Background technique [0002] In clinical practice, skin wounds cannot be sutured directly due to excessive tension of the wound margins. In the past, skin grafting or skin flap transfer operations were needed to repair them. Introduced into the clinical treatment of such wounds that are difficult to suture directly, the principle is to use the looseness and extensibility of the skin, use an external stretcher to pull the skin edges on both sides of the wound toward the center, gradually shrink the wound, and finally suture to eliminate the wound. [0003] According to the above, the retractors of the current clinical prior art, because of their simple structure, single function, and small scope of application, cannot meet the contraction of various wounds, especially for large-area wound skin retractors. Tighten the wound to avoid continuous e...

Problems solved by technology

[0003] According to the above, the retractors of the current clinical prior art, because of their simple structure, single function, and small scope of application, cannot meet the contraction of various wounds, especially for large-area wound skin retractors. Tighten the wound to avoid the continuous expansion of the wound, but the structure is heavy and the operation is complicated, requiring a lot of manual installation and operation of the stretcher to realize the tightening of the two wounds by the stretcher, which increases the burden on the medical staff and also brings Patient rehabilitation brings hidden dangers, and it is difficult to popularize and apply clinically
