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.

Embodiment Construction

[0074] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0075] The invention relates to a hook bar fixing system of an elastic skin dilator clinically used in orthopedics and plastic surgery. The hook bar fixing system includes an adjustment component and a fixing hook device for figure 1 Taking the type I structure of the hook rod fixing system of the elastic skin dilator as an example, each component is explained accordingly. The adjustment assembly includes: threaded rod 1, fixed wheel nut 2, pressure regulating member, pressure regulating spring 4, sliding sleeve 5. And the fixed nut 6, the main part of the threaded rod 1 is in the shape of a cylindrical rod and has an external thread, and the fixed wheel nut 2, the pressure regulating member, and the pressure regulating spring are sequentially arranged on the threaded rod 1 from top to bottom 4. The sliding sleeve 5 and the fixed nut 6; the fixed wheel...

Abstract

The invention relates to an elastic skin expander, a skin traction system of the elastic skin expander and a hook rod fixing system of the elastic skin expander. The elastic skin expander is clinically applied to the orthopedics department and the plastic surgery department and can is adjustable in pressure. The hook rod fixing system comprises an adjusting component and a fixing hook device, wherein the adjusting component comprises a screwed rod, a wheel-fixing nut, a pressure-adjusting component, a pressure-adjusting spring, a slide casing pipe and a fixing nut; the pressure of the pressure-adjusting component applied to the pressure-adjusting spring is read through a slide casing pipe pressure scale meter under the matching between the pressure-adjusting component, the pressure-adjusting spring and the slide casing pipe; the fixing hook device is arranged between the slide casing pipe and the fixing nut and comprises a body part and a hook part which are connected through screw threads or connected in a fastening way or integrally molded.

Description

technical field [0001] The invention relates to an adjustable pressure elastic skin expander for clinical application in orthopedics and plastic surgery, in particular to an adjustable pressure elastic skin expander and its skin traction system and hook bar fixing system. 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 techn...
