Patent abstract
When a probe unit and a sheath unit are coupled to each other, an engaging portion of the probe unit is coupled directly to a vibrator unit through an engaging hole portion if the probe unit is combined with a proper sheath. If the probe unit is combined with an improper sheath, the engaging portion is not allowed to pass through the engaging hole portion. Thus, the probe unit and the vibrator unit can be prevented from being wrongly assembled, and only those parts which wear easily can be replaced. And the same protection system can be applied to an engagement of a sheath unit and a body of ultrasonic surgical instrument.
