The invention relates to a medical apparatus, and provides a ceramic scalpel which aims to solve the technical problem caused by the fixing of a blade and a handle of the existing ceramic scalpel. The ceramic scalpel comprises a ceramic blade and a handle, wherein a through hole is formed in the tail part of the ceramic blade; a mounting groove which inwards sinks along the handle is formed in the side part of the handle body at the front end of the handle, the handle body at the front end of the handle is divided into an upper handle body part and a lower handle body part by the mounting groove, and a rotary shaft pointing into the mounting groove is arranged at the bottom of the tail end of the upper handle body part; an elastic clamping sheet arranged along the handle is arranged in the mounting groove, the integral elastic clamping sheet is tightly fitted with the upper handle body part, and one end, close to the rotary shaft, of the elastic clamping sheet is fixed with the surface of the lower handle body part; after the ceramic blade is positioned in the mounting groove, the rotary shaft penetrates through the through hole in the tail part of the ceramic blade, and the tail part of the ceramic blade is clamped with the upper handle body part by the elastic clamping sheet. The ceramic scalpel has the advantages that the structure is compact and reasonable, the convenience for use is realized, and the ceramic scalpel can be widely applied to various operations.
