Medical ultrasonic applicator for use in an acoustic shock-wave-conducting propagation-medium

摘要

Shockwave generator with an ultrasonic applicator and medical ultrasonic applicator for use in an acoustic shockwave-conducting propagation medium. …??The invention relates to a shockwave generator for generating shockwaves in an acoustic propagation medium with an ultrasonic applicator (15) by means of which, for locating purposes, ultrasonic waves can be introduced into the propagation medium, the ultrasonic applicator (15) having a housing (26) and at least one ultrasonic transducer (21a, 21b, 21c) arranged inside the housing (26), and an ultrasonic applicator (15) of the said type intended for use in an acoustic shockwave-conducting propagation medium. In this case it is proposed that a material be arranged in front of at least part of the area of the housing (26) situated in the propagation path of the shockwaves, this material having an acoustic impedance which deviates considerably from that of the acoustic propagation medium.
