Device for ultrasonic treatment, minimally invasive, of pathologies of the intervertebral discs.

摘要

A device for mini-invasive treatment ultrasonic disc disease, wherein there is provided at least one therapeutic transducer (2) ultrasound treatment of the disc (5) of a patient (4) by generating, by means of said therapeutic transducer (2) ultrasound, a ultrasonic field (3), whose focus (F) temperature is located on the disc (5) for heating thereof, characterized in that - an optical device (20) navigation comprises at least one chamber (21) diagnostic is designed to produce at least one x-ray or image of the anatomic structure (23) of the treatment area (22) within which is located the disc (5) which it treated, - is provided therapeutic transducer (2) ultrasound for introduction through the patient's skin (4) and its engagement with the disc (5), - the therapeutic transducer (2) ultrasound in its distal end (10) has a flexible wall (13) with the ability to adapt to the surface of annulus fibrosus (8); - it is provided at least one chamber (11) cooling liquid (12) cooling at the distal end (10), - is provided at least one transmitter element (9) of ultrasound within the chamber (11) cooling the chamber (11) of cooling between the transmitter element (9) and the flexible wall (13) being located, - the chamber (11) cooling liquid (12) cooling are configured to cool the transmitter element ( 9) and the ultrasonic transducer closest to (2) ultrasound, and tissue - there is provided at least one detector (14) temperature to measure the temperature in the disc (5).
