Environment-friendly neurosurgical skin preparation scalpel

Abstract

The invention discloses an environment-friendly neurosurgical skin preparation scalpel which comprises a shaving part and a handheld part. The shaving part is fixedly installed at the upper end of thehandheld part. The top wall of a shell is of an arc structure so that the skin of a patient can be prevented from being injured. The scalpel is safe and reliable, a blade can retract into the shell through cooperation of an operation handle and a threaded rod when the scalpel is not in use, and the blade can be effectively prevented from injuring the patient or a medical worker by accident. The skin preparation scalpel can be prevented from sliding off to be damaged, and at the same time, the accident that the patient is scratched as the medical worker does not firmly grip the skin preparation scalpel is avoided. The skin preparation scalpel has the lubricant smearing function, so that the trouble that the medical worker has to additionally use a lubricant smearing tool is omitted. A prepared lubricant not only has a good lubricating effect, but also has an anti-microbial effect, so that the preserved skin of the patient after operation is effectively prevented from being affected. Aprepared protection layer can prevent the surface of the shell from being stained with bacteria and hair.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an environment-friendly dermatome for neurosurgery. Background technique [0002] Skin preparation refers to the operation preparation of shaving the hair and cleaning the body surface at the corresponding part of the operation. It is the work of cleaning the operation area before the operation for the patients who are going to undergo surgery. It is not only as simple as removing body hair, but also includes skin. Cleaning, and sometimes skin iodophor scrubbing before surgery. The skin preparation knife is one of the commonly used tools in the skin preparation process. [0003] The dermatome used in neurosurgery in the prior art is not ergonomically designed, and often scratches the patient's skin; the safety performance is poor, and the blade cannot be put away when not in use, which often causes the blade to accidentally injure patients or medical staff; It is ea...

Problems solved by technology

[0003] The dermatome used in neurosurgery in the prior art is not ergonomically designed, and often scratches the patient's skin; the safety performance is poor, and the blade cannot be put away when not in use, which often causes the blade to accidentally injure patients or medical staff; It is easy to slip from the hands of medical staff, and is often damaged due to slipping. At the same time, it often leads to accidents where medical staff can't hold the skin knife and scratch the patient; it does not have the function of applying lubricant, and medical staff need to use it separately The tools for applying lubricant apply lubricant to the patient's skin, which is cumbersome and seriously affects the work efficiency of medical staff; in addition, the lubricant used in conjunction with the skin preparation knife in the prior art has a poor lubrication effect, which easily leads to the patient's surgical skin preparation. skin infection phenomenon; in addition, the neurosurgery dermatome in the prior art lacks protective measures, resulting in poor antiseptic, antibacterial, anti-sticky foreign body, and anti-aging properties, which makes the use of the dermatome more difficult. The life-span is short, and it is particularly important that bacteria and hair are always stuck on the dermatome during use, which does not meet the hygienic requirements for medical equipment use; The dermatome is mostly disposable, cannot be reused, and has poor environmental protection value. Therefore, an environmentally friendly neurosurgery spare dermatome is proposed to solve the above-mentioned technical problems
