DEVICE FOR REMOVAL OF CALCULI |
摘要 |
Device for removal of calculi by using an intracorporeal lithotripter comprises a metallic probe or sonotrode which is excited by an electrically controlled ultrasonic transducer for generating longitudinal oscillations for the fragmentation of calculi via the distal end of the sonotrode, the sonotrode accommodating a coaxially arranged impact probe which for an alternative fragmentation of calculi transfers shock or pressure forces that are generated by the impact energy of a reversibly driven impact member or projectile which periodically hits against a mass bo dy on the proximal end of the impact probe when its drive is alternatively switche d- on.
