The invention relates to a lithotripsy device for fragmenting body stones, wherein the lithotripsy device has a hand-held device with an ultrasonic vibration exciter with an ultrasonic vibration exciter outer diameter and a sonotrode with a longitudinal central axis and a sonotrode outer diameter which can be connected to the hand-held device on the distal side, wherein the sonotrode can be excited to a first vibration by means of the ultrasonic vibration exciter, and the lithotripsy device has a vibration excitation element with a through-opening, wherein the vibration excitation element with the through-opening is arranged around the sonotrode outer diameter and/or around the ultrasonic vibration exciter outer diameter, wherein the through-opening of the vibration excitation element has a larger diameter than the sonotrode outer diameter and/or than the ultrasonic vibration exciter outer diameter so that the vibration excitation element is freely movable, and the vibration excitation element has an imbalance so that, in the event of a rotation of the vibration excitation element about the sonotrode and/or the ultrasonic vibration exciter, the sonotrode can be excited to a second vibration by means of the imbalance. Furthermore, the invention relates to a lithotripsy system, a retrofitting kit for retrofitting an existing lithotripsy device, and a method for operating a lithotripsy device.
Lithotripsy device (101, 201) for fragmenting body stones, wherein the lithotripsy device (101, 201) has a hand-held device (231) with an ultrasonic vibration exciter (103, 203) with an ultrasonic vibration exciter outer diameter and a sonotrode (107, 207) with a longitudinal central axis (117) and a sonotrode outer diameter (108, 208), which can be connected to the hand-held device (231) on the distal side, wherein the sonotrode (107, 207) can be excited to a first vibration by means of the ultrasonic vibration exciter (103, 203), and the lithotripsy device (101, 201) has a vibration excitation element (113, 213) with a through-opening (114, 214), wherein the vibration excitation element (113, 213) with the through-opening (114, 214) is arranged around the sonotrode outer diameter (108, 208) and/or around the ultrasonic vibration exciter outer diameter, characterized in that the through-opening (114, 214) of the vibration excitation element (113, 213) has a larger diameter than the sonotrode outer diameter (108, 208) and/or than the ultrasonic vibration exciter outer diameter so that the vibration excitation element (113, 213) is freely movable, and the vibration excitation element (113, 213) has an imbalance so that, in the event of a rotation of the vibration excitation element (113, 213) about the sonotrode (107, 207) and/or the ultrasonic vibration exciter, the sonotrode (107, 207) can be excited to a second vibration by means of the imbalance.
Lithotripsy device (101, 201) according to any of the preceding claims, characterized in that the vibration excitation element (113, 213) has an imbalance element (115, 215) in its interior and/or on its outer surface.
Lithotripsy device (101, 201) according to any of the preceding claims, characterized in that the vibration excitation element (113, 213) has a recess.
Lithotripsy device (101, 201) according to any of the preceding claims, characterized in that the lithotripsy device (101, 201) has a drive apparatus for driving the rotation of the vibration excitation element (113, 213).
Lithotripsy device (101, 201) according to any of the preceding claims, characterized in that the lithotripsy device (101, 201) has an attachable holder housing (233), wherein the attachable holder housing (233) surrounds the vibration excitation element (113, 213), a proximal end (109, 209) of the sonotrode (107, 207) and/or the ultrasonic vibration exciter (103, 203).
Method (301) for operating a lithotripsy device (101, 201), wherein the lithotripsy device (101, 201) has an ultrasonic vibration exciter (103, 203), a sonotrode (107, 207) with an outer diameter (108, 208), a vibration excitation element (113, 213) with an imbalance and with a through-opening (114, 214), and a drive apparatus for driving a rotation of the vibration excitation element (113, 213), wherein the vibration excitation element (113, 213) is arranged with the through-opening (114, 214) around the outer diameter (108, 208) of the sonotrode (107, 207), and the through-opening (114, 214) of the vibration excitation element (113, 213) has a larger diameter than the outer diameter (108, 208) of the sonotrode (107, 207) so that the vibration excitation element (113, 213) is freely movable, comprising the following steps:
