|発明の名称||PROBE-TYPE LIVING BODY TISSUE RESECTION DEVICE AND PROBE UNIT|
PROBLEM TO BE SOLVED: To provide a probe-type living body resection device capable of both reducing a probe in diameter and improving resection efficiency, and improving cost reduction and maintainability by simplifying the structure.
SOLUTION: In the probe-type living body tissue resection device with a probe unit 10 including: a canalicular-shaped probe 12 with opening apertures for aspirating living body tissue; and a shredding device arranged within the probe for finely cutting the living body tissue aspirated into the probe through the opening apertures 14 of the probe, an aspiration-force supplying device for supplying the aspiration force, and a shredding-drive-source supplying device for supplying power or energy for exerting a function of the shredding device are connected to the probe unit, so that the device cuts the living body tissue finely while aspirating it through the opening apertures for aspiration/resection of the living body tissue. The device has a structure in which a plurality of opening apertures in the probe are formed, and the shredding device has a light guide for emitting a laser beam toward the inner spatial portion of the opening apertures in the probe, thereby finely cutting the living body with the laser beam from the light guide.
