Elastic skin expander and skin traction system and cant hook fixing system thereof

Abstract

The invention relates to an elastic skin expander and a skin traction system and a cant hook fixing system thereof in the clinical application of the department of orthopedics and the department of plastic surgery. The skin traction system is composed of cant hook fixing systems, a stick clip and traction steel needles, each cant hook fixing system is composed of a fixing hook, a needle fixing nut, a rod fixing nut, a sliding sleeve pipe, a pressure adjusting spring, a pressure adjusting wheel and a wheel fixing nut, and a threaded rod is provided with the rod fixing nut, the sliding sleeve pipe, the pressure adjusting spring, the pressure adjusting wheel and the wheel fixing nut in a radial direction. Each traction steel needle is a cylindrical steel needle, a steel wire or a cable, and the stick clip can be classified into a first type, a second type, a third type, a fourth type and other various forms. By means of the elastic skin expander and the skin traction system and the cant hook fixing system of the elastic skin expander, the pressure adjusting wheel is swirled to compress the pressure adjusting spring to receive a counter acting force from fixing clip block by the stick clip, the pressure adjusting spring gives the pressure adjusting wheel the counter acting force to drive the threaded rod, a needle fixing hook, the traction steel needles to exert pulling tension on the skin, the skin gradually expands and grows under the pulling tension, and the wound healing is accelerated.

Description

technical field [0001] The invention relates to an elastic skin expander for clinical application in orthopedics and plastic surgery. Background technique [0002] Orthopedics and plastic surgery sometimes use microsurgical techniques to repair skin defects with vascular pedicle flaps, local flap transfer repairs or free flap transplantation repairs, which are traumatic and risky; sometimes small-area head and face skin defects are treated with The balloon-type skin dilator performs skin stretching and performs partial skin flap transfer and repair, which has few indications, long treatment time, small transfer area, easy compression of deep tissues, and prone to infection at the implantation site of the balloon. Contents of the invention [0003] In order to make up for the shortcomings of the current application of microsurgical techniques or balloon skin dilators in the treatment of skin defects, the purpose of the first invention is to provide a hook rod fixation syste...

Problems solved by technology

[0002] Orthopedics and plastic surgery sometimes use microsurgical techniques to repair skin defects with vascular pedicle flaps, local flap transfer repairs or free flap transplantation repairs, which are traumatic and risky; sometimes small-area head and face skin defects are treated with The balloon-type skin dilator performs local skin flap transfer and repair after stretching the skin. It has few indications, long treatment time, and small transfer area. It is easy to cause compression on deep tissues and infection at the implantation site of the balloon.
