Abstract

The invention relates to a disposable safety scalpel. The disposable safety scalpel comprises a blade, a handle and a sleeve. When the sleeve slides front and back relative to the handle and is located, the blade presents a stretching state and a retraction state from the sleeve. The disposable safety scalpel is characterized in that a first lock opening is formed in the front of a scalpel protection lock opening in the back of the handle, and the scalpel protection lock opening and the first lock opening are in inclined face or cambered face transition. A second lock opening and a stopping block are arranged in the front of a handle front through groove. When a button is in a press state and the sleeve is pushed forwards, an impact head is stopped by the stopping block, so that the impact head slides into the second lock opening from the front end of the through groove, and the condition that the scalpel is pushed into the lock state without being used is effectively prevented. Besides, by the front and back simultaneous lock state, slipping due to overlarge space between the sleeve and the handle and deformation is prevented, and the lock state stability is well guaranteed.
