Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The main components of the annular skin stretcher of the present invention are as follows, see figure 1 :

[0021] 1) steel wire 1, used for pulling the skin edge;

[0022] 2) Steel wire fixing clip 2: One end fixes the steel wire (there is a screw 8 at the top, and the steel wire can be squeezed and fixed in the ring-shaped threading hole at the end after tightening the screw 8), and the other end is connected to the threaded rod 3, which can be threaded along the threaded rod 3. Swipe left and right;

[0023] 3) threaded rod 3: the steel wire clamp 2 slides on it;

[0024] 4) Hollow tube 4: Steel wires can be allowed to cross through. Because of direct contact with the skin, it is recommended to use biocompatible and elastic polymer materials;

[0025] 5) Connecting part 5: a part connecting the threaded rod 3 and the hollow pipe 4, so th...

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.
