Paper Abstract

This paper presents recent results on a combined optical and acoustical system for a new endoscopic controlled laser and ultrasound surgical therapy (LUST). The goal is the combined employment of the cavitation ultrasonic surgical aspiration (CUSA) and the laser in endoscopic surgery. With such a system the CUSA technique can be used for selective tissue cutting and the laser for blood coagulation, vaporization, general tissue cutting (all this with cw lasers) and photoablation (with pulsed lasers). The transmission of acoustical energy via optical fibers is theoretically calculated. First experimental results on the transmission of high power ultrasound (US) via a silica fiber are shown. Furthermore future biomedical applications including angioplasty and endoscopic surgery are discussed.
