Abstract

An ultrasonic lithotripter comprising a first transmission probe which has a hollow portion in the form of a through hole and transmits ultrasonic vibration and a superfine second transmission probe which can be passed through the hollow portion of the first transmission probe. An object of manipulation is held by means of the second transmission probe as it is manipulated by means of the first transmission probe.

Claims

1. A calculus manipulation apparatus comprising:

first and second ultrasonic generator elements which generate ultrasonic vibration;

a first transmission probe having a proximal end portion connected to the first ultrasonic generator element and a hollow portion in the form of a through hole;

a tip manipulator element which is provided on the distal end portion of the first transmission probe and brought into contact with a calculus, the tip manipulator element receiving ultrasonic vibration from the ultrasonic generator elements through the probe; and

a second transmission probe capable of being passed through the hollow portion of the first transmission probe, the second probe having a piercer section on the distal end portion thereof to which ultrasonic vibration is transmitted from the second ultrasonic generator element and which is stabbed into the calculus and a calculus fixing section which fixes the calculus to the distal end portion.

2. A calculus manipulation apparatus comprising:

first and second ultrasonic generator elements which generate ultrasonic vibration;

a first transmission probe having a proximal end portion connected to the first ultrasonic generator element and a hollow portion in the form of a through hole;

a tip manipulator element which is provided on the distal end portion of the first transmission probe and brought into contact with a calculus, the tip manipulator element receiving ultrasonic vibration from the ultrasonic generator elements through the probe; and

a second transmission probe capable of being passed through the hollow portion of the first transmission probe, the second probe having a piercer section on the distal end portion thereof to which ultrasonic vibration is transmitted from the second ultrasonic generator element and which is stabbed into the calculus and a calculus fixing section which fixes the calculus to the distal end portion, wherein the calculus fixing section has means which stops the second ultrasonic generator element with the piercer section in the calculus.
