    摘要： An endoscopic lithotripsy probe apparatus includes a probe, ultrasonic-vibration source, mechanical shock generation source, and switch-mechanism. The ultrasonic-vibration source is detachably attached to the probe to transmit an ultrasonic-vibration to the probe in a state in which the proximal end of the probe is connected to the ultrasonic-vibration source. The mechanical shock generation source, which is disposed on the side of the proximal end of the probe, applies a force to the ultrasonic-vibration source in a state in which the ultrasonic-vibration source is detached from the proximal end of the probe, and allows the ultrasonic-vibration source to collide with the proximal end of the probe so that a mechanical shock is applied to the probe. The switch-mechanism switches a state in which the ultrasonic-vibration from the ultrasonic-vibration source is transmitted to the probe and a state in which the mechanical shock from the mechanical shock generation source is transmitted.

    摘要： A surgical resecting instrument whereby a cartilage, joint bump or tumor within a body cavity such as a joint cavity, for example, of a knee is resected from outside the body cavity without incising it and is discharged out of the body cavity has a body part providing a rotary driving connection and an insertable part to be inserted into a tissue within a living body attached to and extending from a front end part of the body part. The insertable part comprises a tubular outer tube opened in the tip part and forming an outer shell of the insertable part and an inner tube provided within the outer tube and rotated and driven by the rotary driving connection. An outer tubular blade is provided in the tip part of the outer tube. The tip of the outer blade is open and has a slot extending from the tip in a peripheral wall and forming a blade part at an edge of the slot. An inner blade for shearing a living body tissue together with the outer blade part is provided in the tip part of the inner tube within the outer blade. The inner blade has a shearing blade part formed so that the angle formed with the outer blade part at the beginning of a shearing action will be larger than the angle formed with the blade part as the shearing action continues.
