TRANSURETHRAL ULTRASONIC SENSOR FOR TREATING PROSTATE Russian patent published in 2014 - IPC A61N7/02 A61B5/55 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to devices for ultrasonic transurethral therapy of prostate. A sensor compatible with magnetic resonance equipment comprises an axially pivot ultrasonic element, a adjoining rod providing a support for the ultrasonic element and a possibility of pivoting motion together with it, fluid canals enclosed into the rod for the cooling and acoustic contact fluid circulation, an acoustic membrane fixed to enclose the ultrasonic element and retaining the acoustic contact and cooling fluid, and a rigid outer case attached to the acoustic membrane and configured to comprise the ultrasonic element and the rod, and to provide free rotation of the ultrasonic element and the rod in the case so that the ultrasonic element and the rod turns around the outer case and the acoustic membrane. When operating the sensor, it is positioned in a tubular passage so that the acoustically transparent membrane provides acoustic accessibility to a target along the whole circular length of the tubular passage; the target is exposed to the ultrasonic element through the acoustic membrane along the circle of the tubular passage, and the ultrasonic element is cooled down through the fluid canals integrated into the rod. A magnetic resonance visualisation system comprises a magnet generating a static magnetic field within an examination field, a high-frequency transmission coil configured to excite a magnetic resonance and to manipulate the magnetic resonance within the examination field and/or to obtain magnetic resonance data from the examination field, and a sensor.

EFFECT: using the invention enables relieving side effects and providing therapy without physical injuries of surrounding tissues.
