Abstract: In a laser scalpel (Fig. 1) for surgical purposes the energy of a laser beam emitted from the handpiece (4) onto an operation field can be changed within limits guaranteeing safety by means of pressure keys (DW, UP) arranged on a handpiece (4) held in the surgeon's hand during operations. Every required power change can be made without risk and simply by finger pressure of the surgeon himself/herself, and the course of the operation is not interrupted thereby.

Abstract: A laser surgical knife characterized by switches, which can adjust an output power within the safe scope from the output power preliminarily set for a laser oscillator, mounted on an attachment of said laser surgical knife which is held by an operating surgeon's hand in order to irradiate laser rays on the affected parts. The present invention can provide a laser surgical knife of which output power can be changed at one touch and in safe without interrupting surgical operations merely by a simple process in which an operating surgeon operates a handy switch for hinself.
