HIGH-AMPLITUDE ACOUSTIC SYSTEM FOR ULTRASONIC SURGERY AND THERAPY Russian patent published in 2010 - IPC A61N7/00 A61H23/00 A61B17/22 B06B1/06 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to acoustic systems used in ultrasound medical devices applied in surgery and medical treatment. An acoustic system contains a pin-ended oscillation concentrator connected a longitudinal piezoelectric transducer presented with a package piezoelectric cell antenna, with an annular insulator, and compressed with a reflective patch. The reflective patch is composite, and comprises a disk with a central hole and a sleeve nut contacting thereto and attached by a threaded connection to an input end face of the oscillation concentrator to tighten the annular piezoelectric cell with an in-between disklike terminal electrode connected with a centre damped wire integrated in the piezoelectric transducer and connected through the central hole of the reflective patch disk with a supply cable pin of an ultrasound generator. Another pin is connected with a terminal attached to an end face of the sleeve nut, with a central hole formed therein. The annular insulator is placed in a gap between the packaged piezoelectric cells, disklike terminal electrode and an internal diametre generatrix of the sleeve nut. In the voltage antinode of the oscillation concentrator, there are provided diametrical and opposite spline grooves to be connected with coupled flanges on a cone-shaped holder of a split bearing casing.

EFFECT: use of the invention allows higher system reliability, downsizing and prolonged active service.
