An instrument that stretches/expands skin tissue at the edges of ulcers, wounds

Abstract

An instrument for stretching / expanding skin tissue located at the edges of ulcers and wounds, comprising: a first splint part and a second splint part (10, 12) from which at least one engaging element is Each of the engaging elements extends, the distal end of the engaging element is adapted to engage the skin tissue to be stretched; an elastic member connects the splint members (10, 12) and exerts an opposite force on the splint members when subjected to traction force; and with A device for adjusting the distance separating the splint members (10, 12) in the absence of traction on the elastic members.

Description

technical field [0001] The present invention generally relates to an apparatus for stretching / expanding skin tissue at the edges of ulcers and wounds, particularly for treating skin lesions whose edges cannot be closed directly, which require secondary healing (fresh tissue growth) into a wound suitable for primary healing (suturing). Background technique [0002] Chronic skin damage is an increasingly common disease, especially in first world countries, where it affects 0.4%-1% of the population. The process used to heal chronic skin lesions (ulcers) proceeds in two ways: epithelialization and / or granulation tissue growth. The degree of contraction determined by the activity of myofibroblasts contributes to the repair process. Another medically established fact is that soft tissues subject to traction or load tend to expand (skin expanders, pendants for plastic surgery, etc.).
