Invasive-endoscopic therapy instrument with duct for simultaneous transmission of ultrasound and laser radiation - has at least one wave conductor for transmission of sonic energy of proximal ultrasonic source and transmission of light energy from proximal laser radiation source
The therapeutic instrument includes a conductor through which sound or light energy is transmitted to the distal end of the instrument. The intensity and the frequency of the sound produced from the ultrasonic source (22) is so selected, that it is adequate for the cutting of tissue. The ultrasonic...

| description | The therapeutic instrument includes a conductor through which sound or light energy is transmitted to the distal end of the instrument. The intensity and the frequency of the sound produced from the ultrasonic source (22) is so selected, that it is adequate for the cutting of tissue. The ultrasonic power transmitted to the distal end amounts to at least 5 watt and its frequency is less than 1 MHz, pref. between 30 and 200 kHz. The intensity and the frequency of sound produced by the source (33) or from a separate second ultrasonic source, is so selectable, that it is suitable for diagnosing tissue damage. The dia. of the wave-conductor is larger than 0.05 mm or smaller than 0.1 mm. USE/ADVANTAGE - Neurosurgery. Quartz glass fibre wave conductors can transport sound energy as well as light energy. Ultrasonic energy and laser energy can be used simultaneously or during same treatment operation inside body of patient. |
