OSCILLATING LITHOTRIPTER TIP

摘要

A tip element for a lithotripter is provided. The tip element includes a proximal end configured for attachment to a waveguide of the lithotripter and a distal end configured for placement against at least one urinary tract stone. The lithotripter transmits energy from the tip element to the at least one urinary tract stone to break up the at least one urinary tract stone into fragments. The tip element may further include a tip element passage that extends between the proximal end and the distal end. The tip element passage communicates with a lumen of the waveguide for at least one of suctioning and irrigating a urinary tract. The distal end has one or more sharp edges to maintain contact between the at least one urinary tract stone and the distal end during suctioning. The distal end may be configured to limit the size of fragments from the at least one urinary tract stone drawn into the tip element passage during suctioning.
