METHOD AND DEVICE FOR INVASIVE OR ENDOSCOPIC THERAPY USING ULTRASONIC AND LASER ENERGY

Described is an endoscopic instrument which transmits simultaneously acoustic energy from a proximal source (30) and laser radiation from a laser-therapy laser (17) through flexible waveguides (3) into the interior of the body. The power and frequency of the acoustic energy lie in a band sufficient...

Beschreibung
Zusammenfassung:	Described is an endoscopic instrument which transmits simultaneously acoustic energy from a proximal source (30) and laser radiation from a laser-therapy laser (17) through flexible waveguides (3) into the interior of the body. The power and frequency of the acoustic energy lie in a band sufficient to cut tissue (16) and the therapy laser (7) operates preferably in the near infra-red. The waveguides are quartz-glass fibres (3) which can convey both acoustic and light energy. Un instrument endoscopique transmet simultanément dans le corps, l'énergie acoustique d'une source sonore (30) disposée proximalement et du rayonnement laser d'un laser de thérapie (17) par l'intermédiaire d'un guide d'ondes (3) souple. L'énergie sonore se situe dans une plage de puissance et de fréquence suffisante pour sectionner des tissus et le laser de thérapie travaille de préférence dans l'infrarouge proche. Les guides d'ondes sont des fibres de verre quartzeux (3) qui transportent aussi bien de l'énergie acoustique que de l'énergie lumineuse.
