Medical scalpel

Abstract

The invention discloses a medical scalpel. The medical scalpel comprises a scalpel handle, wherein a piezoelectric body is arranged in the scalpel handle; a push rod is arranged at the upper part of the piezoelectric body; convex teeth are arranged at one end, far away from the piezoelectric body, of the push rod; a rotating gear is arranged below the convex teeth; the rotating gear is meshed withthe convex teeth; a rotating column is arranged at the right side of the rotating gear; a second scalpel handle is arranged at the right side of the rotating column; a blade clamping column is arranged at the right side of the second scalpel handle; a blade clamping groove is arranged at a position, corresponding to the blade clamping column, of a blade; concave holes are arranged at one end, faraway from the second scalpel handle, of the scalpel handle; and a cold and hot switch and a steering switch are arranged in the concave holes. According to the invention, when an operation is performed, tissues like skin and muscles on the surface of a human body and normal tissues and diseased tissues in the human body are cut open; a traditional straight-handle scalpel is used all the time; thetissues on the surface of the human body are convenient to be cut open, but the tissues hidden in the human body are inconvenient to be cut open in the aspect of cutting operation; and thus, a straight-handle scalpel handle sometimes becomes a great burdensome in the surgical 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...

Problems solved by technology

Determine the lesion site according to the examination before the operation, but it is possible to find that the lesion tissue deviates after the tissue is cut during the operation. In this case, the surgical incision may need to be enlarged to fully expose the surgical field of view
