Abstract

The invention discloses a concentric circular skin stretching closer which comprises a concentric circle pull rod and two sliding hooked needles, the concentric circle pull rod is of a semi-circular structure, the two sliding hooked needles are slidably arranged on the concentric circle pull rod, each sliding hooked needle comprises a sliding frame and a plurality of hooked needles, each hooked needle is in a shape of a C-shaped structure, the concentric circle pull rod is slidably sleeved with the sliding frame, and the directions of the hooked needles on the two sliding hooked needles are opposite. According to the concentric circular skin stretching closer, the two sliding hooked needles walk along the concentric circular pull rod to repeatedly stretch skin, so that the skin is stresseduniformly, the skin tissue is powerfully protected, meanwhile, the concentric circular skin stretching closer can adapt to different limb diameters and can be used for stretching arc-shaped large wounds of limbs, and the defect of planar stretching of an existing stretching device is overcome.

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 ...
