Problems solved by technology

[0002] Most of the existing surgical scalpels are only composed of a blade and a handle. During use, the depth of skin cut by the scalpel is completely controlled by the chief surgeon based on experience and feeling. It is a dangerous challenge for trainees and for patients. More injuries may be suffered, even experienced doctors may occasionally have accidents, a surgical scalpel with precise and controllable cutting depth is still blank

Abstract

A method for using a high-precision scalpel according to the present invention belongs to the field of medical equipment. The ordinary surgical scalpel is improved, and a bracket is installed behind the cutting blade. Scale, the two sides of the cutting blade are respectively provided with a piece of the same limit piece to connect with the knife body, the inside of the knife body is equipped with a bracket, and the second half of the knife body is installed with an adjusting nut and a lock nut that are intermeshed with the strip bolts. This structure can precisely control the cutting depth of the surgical blade.

Description

technical field [0001] The invention relates to a method for using a high-precision scalpel, which belongs to the field of medical devices, and particularly relates to the precise and adjustable depth of the scalpel when cutting skin. Background technique [0002] Most of the existing surgical scalpels are only composed of a blade and a handle. During use, the depth of skin cut by the scalpel is completely controlled by the chief surgeon based on experience and feeling. It is a dangerous challenge for trainees and for patients. More injuries may be suffered, and even experienced doctors may occasionally have accidents, and a surgical scalpel with precise and controllable cutting depth is still blank. Contents of the invention [0003] A method for using a high-precision scalpel of the present invention overcomes the above-mentioned defects. The ordinary surgical scalpel is improved, and a bracket is installed behind the cutting blade. Scale, the two sides of the cutting b...
