<p>[PROBLEMS] To provide a skull cut-off device capable of performing craniotomy operation easily in safety while reducing burden on the patient and closing the head only with a bone flap without relying upon a fixing tool. [MEANS OR SOLVING PROBLEMS] A skull cut-off device for cutting off a skull by means of laser comprises a body (1) for emitting laser (R) introduced from a laser oscillator (200) through an optical fiber (300) from an exit opening (1a) provided at the distal end, a contact portion (2) provided in the body (1) to determine the posture of the body (1) such that a predetermined distance is set between the surface of the skull (P) and the exit opening (1a) by touching the surface of the skull in a predetermined mode, a supporting lever (31) of a predetermined length extending from the body (1) toward the emitting direction of the laser (R) while avoiding the optical path of the laser (R), and a light interception board (32) provided at the distal end of the supporting lever (31) to block farther advance of the laser (R) by interfering with the laser beam path.</p> |
