Abstract:
An instrument for performing invasive and endoscopic work at a work location, the instrument having a proximal end and a distal end and comprising:an ultrasound source for supplying ultrasound energy provided at or coupled to the proximal end of said instrument and supplying an intensity and frequency of ultrasound at said distal end adequate for cutting tissue;a laser for supplying light energy and said laser being also coupled to the proximal end of said instrument and providing a laser light intensity in a therapeutic range;an elongated waveguide for transmitting said ultrasound energy and said laser light energy from the proximal end to the distal end of said instrument;said elongated waveguide being configured to transmit to said distal end at least 5 W of said ultrasound energy at a frequency of less than 1 MHz; and,said elongated waveguide being made of glass transparent to said light energy and being a single waveguide for guiding both said laser light energy and said ultrasound energy.
