Title: Surgical instrument and hand piece
Inventor: MORI EIJI
IPC: A61B18/00
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a surgical instrument and a hand piece making it easy to perform an operation or process on areas that the difficult to handle with conventional surgical instruments and hand pieces of the type causing vertical vibration. SOLUTION: The surgical instrument 10 achieves hemostasis using frictional heat by pressing an affected area against a side face of a shaft-like tool 12 as the side face of the tool 12 vibrates in a direction perpendicular to an axial direction, because vibration transmitted to the tool 12 is torsional vibration. In this case, an end face of the tool 12 without axial vibration does not collide against the affected area, reducing stimuli to the affected area as compared with conventional surgical instruments of the type causing vertical vibration. Thus, hemostasis can be achieved for such affected areas as are difficult to handle with conventional surgical instruments of the type causing vertical vibration.
