The invention discloses an expansion adjustable protective case for surgical electric knife heads. The expansion adjustable protective case comprises a shell, a sliding key and a constraining assembly. A sliding through hole is formed in the upper wall of the shell along the length direction of the shell, a sliding guide plate is arranged in a cavity of the shell in a floating manner, is arranged below the sliding through hole and can float up and down; the sliding key comprises a movable plate and a sleeve, the movable plate is in sliding connection with the sliding guide plate, the sleeve is used for wrapping the electric knife heads, and a sliding button is arranged on the upper surface of the movable plate, is exposed out of the sliding through hole and is used for driving the movable plate to slide; the constraining assembly comprises a constraining protrusion or constraining grooves and a plurality of positioning clamp grooves or positioning protrusions, the constraining protrusion is arranged on the upper surface of the movable plate, the constraining grooves are formed in the upper surface of the movable plate, the positioning clamp grooves are formed in the inner wall of the cavity of the shell and are matched with the constraining protrusion, and the positioning protrusions are arranged on the inner wall of the cavity of the shell and are matched with the constraining grooves. The expansion adjustable protective case for the surgical electric knife heads has the advantages that the expansion adjustable protective case is simple in structure, the exposed lengths of the electric knife heads can be effectively adjusted, and accordingly the surgical safety coefficients can be increased.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a telescopic and adjustable surgical electric knife head protective cover. Background technique [0002] High-frequency electric knife (high-frequency surgical device) is an electrosurgical instrument that replaces a mechanical scalpel for tissue cutting. It heats the tissue when the high-frequency and high-voltage current generated by the effective electrode tip contacts the body, and realizes the separation and coagulation of the body tissue, thereby achieving the purpose of cutting and hemostasis. With the development of medical science, electric knife is widely used in plastic surgery, oral and maxillofacial surgery, thoracoabdominal surgery and other occasions. Generally speaking, the length of the cutting head required for different tissue parts is often different, but the existing electric knife has the problem that the length of the metal part of the cutting head canno...
