Abstract

The invention discloses a combined type skin expander which solves the technical problems that a skin expander used in the prior art can not expand the skin in any direction and a wound surface covering device for vacuum sealing drainage in the prior art can not allow a wound surface to be observed at any time. According to the technical scheme, the combined type skin expander comprises a fixed component and a moving component; the fixed component is located in the moving component and comprises a first cover board, a second cover board, a first porous foam-shaped structure, a first negative pipe, a first washing pipe, a first annular air bag, a traction line, a traction hook and a sealing bolt, and the moving component comprises a third cover board, a second porous foam-shaped structure, a second negative pipe, a second washing pipe and a second annular air bag; the elements of the fixed components and the elements of the moving component can be cut and assembled according to the wound surface and the body surface. The combined type skin expander has the advantages that the skin can be expanded in any direction, the wound surface and the expanded skin can be observed at any time, and safety is high.

Description

technical field [0001] The present invention relates to a skin stretcher. Background technique [0002] In 1976, Barrer first used the skin stretching method to treat the excision of small skin lesions and the repair of skin defects, which was called the retention bridge method. In 1986, Gibson et al. hooked the skin to the skin margins on both sides of the skin defect area, stretched it during the operation, pulled it every 3 minutes for 1 minute, and repeated it 4 times until the wound was closed. This method was called the cyclic loading method. . [0003] Applying the skin stretcher to close the wound has achieved good results in clinical application. The treatment of skin defects has no complications of complicated two-stage repair and reconstruction, and the patient suffers less pain and the treatment cost is low. The complications of skin stretching mainly include: ischemic necrosis of the stretched skin edge, opening of the stretching device from the skin, local in...
