Embodiment Construction

[0067] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses. The invention relates to a stone crusher for crushing stones.

[0068] A lithotripter for crushing stones in a patient is provided. The rock crusher may include a motor (which may have multiple drives) with at least two modes of operation. The motor is configured to generate a first waveform and a second waveform. The waveguide shaft is configured to transmit the first waveform and the second waveform to the stone. In some forms, at least one of the first waveform and the second waveform is provided to the stone at a frequency approximately equal to a natural frequency of the stone.

[0069] Referring to the drawings, wherein like reference numerals refer to like parts, and in particular reference Figure 1A , which illustrates an example of a rock crusher according to the principles of the present disclosure, and is generally designated at 10 . ...

Abstract

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.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Patent Application No. 61 / 821,518, filed May 9, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to medical devices, and more particularly to lithotripters for breaking up stones in a patient. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0005] Lithotripsy is a common procedure used to break up stones or accumulated stones in the urinary tract, kidneys, and / or bladder. Most lithotripsy devices use ultrasonic, laser, or pneumatic energy to break up these stones. Typically, a rock crusher includes a shaft connected to an electrically controlled drive or a pneumatic actuator. The shaft is inserted into the patient's anatomy close to the stone, and a waveform is sent through the shaft to ...
