A surgical skin expansion protector

Abstract

The invention belongs to the field of medical devices, in particular to a skin expansion protector for surgery. A drive shaft is rotatably connected to the inner wall of the bottom of the fixed chamber of the fixed seat, and the two connecting seats on the side where the two spoon heads are close to each other are locked respectively The first rotating shaft and the second rotating shaft are installed, and the ends of the first rotating shaft and the second rotating shaft close to each other extend into the fixed chamber, and the end of the driving shaft and the first rotating shaft are fixedly sleeved with bevel gears that mesh with each other, and the fixed chamber The indoor rotation is connected with a fixed shaft, the driving shaft and the fixed shaft are fixedly set with pulleys, the fixed shaft is screwed with a moving plate, one side of the moving plate is fixedly connected with a gear plate, and one end of the second rotating shaft is fixed The gear meshing with the tooth plate is connected, the top rectangular seat of the fixed seat is slidably connected with a hand-holding post, and the top of the hand-holding post is fixedly connected with a handle, which can effectively prevent the skin dilator from breaking and reduce the pain of the patient. The spoon head is easy to install and disassemble, convenient to 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
