EXTRACORPOREAL LITHOTRIPSY APPARATUS FOR THE DISINTEGRATION OF CALCULI HAVING AN UNATTENUATED LOCATING FIELD |
摘要 |
A shock wave source of the type suitable for treating calculi in the body of a patient has a closed space filled out by a coupling fluid, as well as a hollow-cylindrical, air-filled space, centrally located in the shock wave head, which does not attenuate x-rays. The centrally located space allows for acceptance of an ultrasound locating system. It is covered on the application side by a flexible foil, providing for a shock wave head which is free from contamination of particles from the opening of the above mentioned space to the application surface of the patient.
