Rotary cutter for treating skin disease

Abstract

A rotary cutting tool for the treatment of skin diseases pertains to the technical field of medical devices, which is used for overcoming the shortcoming of difficult control of the cut depth of the existing rotary cutting tool. The rotary cutting tool is composed of a handle body and a drill chuck, a micro-motor is arranged in the handle body, a telescopic sleeve device is increasedly arranged on the drill chunk, the tail end of the telescopic sleeve of the device is positioned in a trepan boring at the front end of an outer sleeve, the front end of the telescopic sleeve extends out of the outer sleeve, the tail end of the outer sleeve can be sheathed on the body of the drill chuck directly or by a regulating sleeve, one end of a spring in the trepan boring pushes against the telescopic sleeve, and the other end pushes against the outer sleeve. The outer surface of the telescopic sleeve is provided with scale, the front end can be provided with a transparent sleeve mouth, thus carrying out smooth and precise cut under the increase of the contact pressure function of the telescopic sleeve; the rotary cutting tool can collect the debris and the droplets of a lesion part by the telescopic sleeve, prevent a blade of the rotary cutting tool from damaging other persons and prevent the rotary cutting tool from being collided and damaged; the rotary cutting process is observed through the transparent sleeve mouth, thus leading a contact pressure tip to contact the skin comfortably; the rotary cutting tool regulates the axial position and the forward extension amount of the telescopic sleeve by a regulating sleeve, which is applicably used as minimally invasive surgical instruments for the treatment of the skin diseases.

Description

technical field [0001] The invention relates to a device for treating skin diseases, in particular to a rotary cutter for removing lesions by rotary cutting, and belongs to the technical field of medical devices. Background technique [0002] Plantar warts, corns, microblood hemorrhoids, and pigmented hemorrhoids are common skin diseases and frequently-occurring diseases. The traditional treatment methods include surgical resection, external application of drugs, liquid nitrogen freezing, laser, microwave, and ionization cautery. Surgical resection involves more bleeding, more pain for patients, long treatment time, and high cost; external application of drugs has poor curative effect, long treatment time, and low cure rate; liquid nitrogen freezing method causes great damage to surrounding normal tissues, low cure rate, and easy recurrence; laser It is not easy to control the burning depth and area of ​​equal burning method. In order to overcome the deficiencies of the abo...

AI Technical Summary

Problems solved by technology

The following problems exist in the use of electric mechanic drills: First, the depth of rotary cutting can only be controlled by hand feeling, and it is difficult to accurately control the depth of cutting. Too deep cutting damages normal tissues, and the depth of cutting is not enough. Repeated cutting greatly increases the pain of patients. , often affects the effect of minimally invasive surgery; second, during the operation, the fragments and droplets of the lesion under the rotary cutting splash around, which is very unhygienic; third, when the rotary cutter leaves the lesion for a short time during the operation, the sharp and The rotary cutting blade is easy to touch the human body or other objects, resulting in unnecessary injury or damage to the rotary cutting blade; Fourth, the rotary cutting blade is always exposed during postoperative storage, which is prone to vibration, vibration, etc. caused by improper storage and carelessness. Knock and other damage rotary cutting edge
