Abstract

The invention discloses a concentric circular skin stretch closure device, which comprises a concentric circle pull rod and a sliding hook, the concentric circle pull rod is a semi-circular structure, the number of the sliding hook is two, and the two sliding hooks are slidably arranged on the concentric circle On the pull rod, the sliding crochet hooks include a sliding frame and several crochet hooks. The crochet hooks are in a C-shaped structure. The sliding frame is slidably sleeved on the concentric circle pull rods. The concentric circular skin stretcher uses two sliding crochet needles to walk along the concentric rods to repeatedly pull the skin, so that the skin is evenly stressed and effectively protects the skin tissue. At the same time, it can adapt to different diameters of limbs and can be used for curved large wounds on limbs. The distraction improves the disadvantages of the plane stretching of the current distractor.

Description

technical field [0001] The invention relates to the technical field of skin stretching instruments, in particular to a concentric circular skin stretching closer. Background technique [0002] In recent years, for large-area skin and soft tissue defects caused by trauma, in addition to traditional free skin grafting, skin flap technology, tissue engineering, skin expansion, stem cell transplantation and other technologies, skin stretching technology has gradually increased and achieved good results . The application principle of skin stretching is to use the mechanical creep properties of the skin. However, there are many limitations in skin stretching, such as limited stretching degree, unclear limit value of stretching force in each part, skin edge necrosis after excessive stretching, etc. Among them, it is more difficult to stretch the large-area wounds of the extremities, because the wounds are distributed on the cylindrical limbs, not on the same horizontal plane and ...
