Ultrasonic piezoelectric disintegrater |
摘要 |
This invention relates to piezoelectric transducers for generating ultrasonic oscillations having an end fitting joined to a distal metal element of a transducer which is connected to a wire emerging in the form of a loop structure. The invention consists in that the loop structure receiving the stone which is to be broken up comprises several wire strands forming a basket, which are coupled together at the extremities of the basket by means of tubular coupling elements and extent to the end fitting in twisted form.
