The invention discloses a medical scalpel, which comprises a knife handle, a piezoelectric body is arranged in the knife handle, a push rod is arranged on the upper part of the piezoelectric body, and a protruding tooth is arranged on the end of the push rod away from the piezoelectric body. A rotating gear is arranged under the convex teeth, and the rotating gear is meshed with the convex teeth. A rotating column is arranged on the right side of the rotating gear, a second knife handle is arranged on the right side of the rotating column, and a second knife handle is arranged on the right side of the second knife handle. The blade clamping post is provided with a blade clamping groove corresponding to the position of the blade clamping post on the blade, wherein a recess is provided at the end of the knife handle away from the second knife handle, and a hot and cold switch and a steering switch are provided in the recess. When performing surgery, the traditional straight-handled scalpel is always used to cut the skin, muscle and other tissues on the surface, as well as normal and diseased tissues in the body. For some tissues, in the cutting operation, the straight handle surgical knife handle sometimes becomes a big burden in the operation process.
Description
technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a medical scalpel. Background technique [0002] The scalpels used by surgeons in hospitals are divided into blades and handles. The blade is disposable, but the handle is not. They are all autoclaved before use, and can be recycled after strict disinfection. The shape of the handle of a knife used now is all straight, and then it can be directly connected to a disposable blade for use. [0003] When performing surgery, the traditional straight-handled scalpel is always used to cut the skin, muscle and other tissues on the surface, as well as normal and diseased tissues in the body. For some tissues, in the cutting operation, the straight handle surgical knife handle sometimes becomes a big burden in the operation process. Before the operation, the lesion site is determined according to the examination, but it is possible to find that the lesion tissue d...
