Annular skin stretching device

Abstract

The invention provides an annular skin stretching device, comprising a stretching line, a rod body, a hollow pipe, and retaining clips which can slide relative to the rod body. A wound surface skin is continuously sutured by the stretching line. After suture, the tail ends of two sides of the stretching line intersect and pass through the hollow pipe, and the tail ends of two sides of the stretching line are respectively tensioned on the retaining clips on the corresponding sides. The retaining clips move a certain distance towards the corresponding ends of the rod body, so under the action of the stretching line, the skin around the wound surface is stretched to a certain degree to the center of the wound surface, and then the retaining clips are fixed on the rod body, to keep stretching. The skin around the wound surface continuously tightens toward the center of the wound surface under the action of the stretching line, so as to gradually reduce the wound surface. The device is simple, light and handy in structure, and has little influence on motion of a patient. The device is suitable to be used in irregular skin defects, and can reduce economical burden of the patient.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to an annular skin stretcher. Background technique [0002] Trauma has been harmful to human health since ancient times. With the continuous progress of society, industrialization, agricultural modernization, and the development of transportation, trauma has not decreased, but has increased. The treatment of skin and soft tissue defects caused by trauma has always received great attention. In clinical trauma orthopedics, wounds with skin and soft tissue defects are often encountered. The traditional treatment method is to change the dressing after debridement, clean the wound, and perform skin grafting to close the wound after the granulation tissue grows well. Traditional skin grafting treatment has complications such as infection at the donor site, extravasation of tissue fluid at the donor site, deep vein thrombosis of the extremities, and peripheral nerve injury.

Problems solved by technology

[0005] The implementation of skin stretching requires the help of skin stretching devices. Although there are many types of skin stretching devices for skin stretching, each has different shortcomings, which limits the wide application of skin stretching.

For example, some distractors are bulky, difficult to install, and not comfortable to wear; some distractors cannot stretch accurately, that is, the adjustment method is relatively extensive
