  • Impact drill lithotripter
    Patent number: 10117660
    Abstract: A lithotripter includes a motor operable to produce a rotational motion, a first cam with a first set of teeth, and a second cam with a second set of teeth configured to selectively engage with the first set of teeth. The first cam is coupled to the motor so that the rotational motion produced by the motor produces rotational motion of the first cam, and the selective engagement between the first set of teeth and the second set of teeth converts the rotational motion of the first cam to a linear waveform that is transmitted through the second cam. The motor, the first cam, and the second cam are disposed in a driver housing, and a wave guide shaft is coupled to the second cam. The wave guide shaft transmits the linear waveform to at least one urinary tract stone to break up the at least one urinary tract stone into fragments.
