Abstract

The invention relates to an adjustable minimally invasive skin cutting knife. The skin cutting knife comprises a handle and a blade connected to the handle. The handle is provided with a groove and a through hole communicated with the groove; the groove is internally provided with an abdicating slot; the handle is internally provided with an installation hole; and the transverse installation hole transversely penetrates the abdicating slot. The blade is sleeved with a stopper ring; a tooth bar is arranged on one side of the stopper ring; all the tooth openings of the tooth bar are inwardly arranged; the tooth bar is arranged in the groove and the through hole; the transverse installation hole is internally provided with a rotating shaft; an adjusting gear engaged with the tooth bar is connected to the rotating shaft in a sleeving manner; and the adjusting gear is arranged in the abdicating slot. According to the invention, the movable stopper ring is added to the blade of a conventional operating knife, the stopper ring is adjusted as needed before the operation, the stopper ring is located on the blade, and the knife cutting depth during the operation can be effectively restricted through the stopper ring, so that the accuracy of the operation is improved, the working efficiency is improved, and the risk of medical accidents caused due to a condition that the operating knife cutting depth is excessive or insufficient is reduced.

Description

technical field [0001] The invention relates to a minimally invasive skin scalpel, in particular to an adjustable minimally invasive skin cutter. Background technique [0002] The scalpels used by surgeons in the hospital are divided into blades and handles. They are autoclaved every time they are used. The so-called sterilization is to kill all microorganisms, so as long as they are strictly sterilized, you don’t have to worry about this problem. Traditional scalpels are used for surgery. The depth of the puncture is determined by the doctor's clinical experience, and errors may occur, resulting in inaccurate puncture volume and affecting the operation process. After searching, no existing scalpel was found, and it can be used during the operation. Control, the amount of knife entry, so the applicant has more defects in the prior art, and designed the original skin cutter, which can control the amount of knife entry, which improves the accuracy of the doctor during the oper...
