Skin expansion protector for surgery department

Abstract

The invention belongs to the field of medical instruments, and particularly relates to a skin expansion protector for the surgery department. The inner wall of the bottom part of a fixed cavity of a fixed seat is rotationally connected with a driving shaft; a first rotating shaft and a second rotating shaft are clamped on two connecting seats on the sides, close to each other, of two spoon heads respectively; the ends, close to each other, of the first rotating shaft and the second rotating shaft extend into the fixed cavity; the driving shaft and one end of the first rotating shaft are fixedly sleeved with bevel gears engaged with each other; the interior of the fixed cavity is rotationally connected with a fixed shaft; the driving shaft and the fixed shaft are each fixedly sleeved with abelt wheel; the fixed shaft is in threaded connection with a movable plate; one side of the movable plate is fixedly connected with a toothed plate; one end of a second rotating shaft is fixedly connected with a gear engaged with the toothed plate; a hand-holding column is connected onto a rectangular seat at the top part of the fixed seat; and the top part of the hand-holding column is fixedly connected with a handle. A skin expander can be effectively prevented from being cracked, and the pain of a patient is reduced; and the spoon heads are convenient to install, remove and use.

Description

technical field [0001] The invention belongs to the field of medical instruments, and relates to a surgical skin expansion protector. Background technique [0002] The working principle of the dilator is to implant under the normal skin and soft tissue near the lesion, and to increase the capacity of the dilator by intermittently injecting liquid into the dilation sac, so that it can exert pressure on the surface skin and soft tissue, and the tissue and epidermis can be stimulated locally through the expansion mechanism. The division and proliferation of cells and the widening of the intercellular space increase the area of ​​the skin. In the plastic surgery of the burn department, it is often necessary to pre-embed a skin expander on the skin. [0003] The existing skin dilator has no good protection measures, and because the dilator is very thin, it is very easy to be punctured when the needle is stitched. Once the skin dilator is punctured, the skin dilator needs to be re...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention solves the problem that the existing skin dilator does not have good protection measures. Since the dilator is very thin, it is very easy to be punctured when sewing needles. Once the skin dilator is punctured, the skin needs to be re-embedded The dilator not only increases the pain of the patient, affects the treatment effect, but also increases the burden on the doctor, so a surgical skin expansion protector is proposed
