Abstract
Abstract A device for neutralization of calculi in the urinary tract, ureteral tract and kidney comprising a probe means and a piezoelectric transducer for producing ultrasonic vibration in the probe means. The transducer has piezoelectric discs disposed between a base member and a sound transmitting member. Mechanical means are provided to tightly hold the base member, piezoelectric discs and sound transmitting member together. The transducer is interconnected with the probe means for transmitting ultrasonic vibrations from the transducer to the probe means. The mechanical means in a specific embodiment comprises a onepiece bolt having a cross-section along its end portion of an exponential horn which is reduced exponentially as a function of its length. The end of the horn-shaped end portion is designed as a cylindrical, straight socket having an internal bore into which rigid or flexible vibrating probes may be attached. the probe means includes a light conductor of a cystoscope with a common flushing probe member about which water circulates.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
93 words
A device for neutralization of calculi in the urinary tract, ureteral tract and kidney comprising: a. a probe means, b. a piezoelectric transducer for producing ultrasonic vibrations in the probe means, c. said transducer having a base member, a sound transmitting member and piezoelectric discs disposed between the base member and the sound transmitting member, d. mechanical means for tightly clamping the base member, piezoelectric discs and sound transmitting member together, and e. means for interconnecting said transducer to the probe means for transmitting ultrasonic vibrations from the transducer to the probe means.
Claim 2
Independent Claim
93 words
A device for neutralization of calculi in the urinary tract, ureteral tract and kidney comprising: a. a probe means, b. a piezoelectric transducer for producing ultrasonic vibrations in the probe means, c. said transducer having a base member, a sound transmitting member and piezoelectric discs disposed between the base member and the sound transmitting member, d. mechanical means for tightly clamping the base member, piezoelectric discs and sound transmitting member together, and e. means for interconnecting said transducer to the probe means for transmitting ultrasonic vibrations from the transducer to the probe means.
Claim 3
Dependent Claim
47 words
A device as defined in claim 1 wherein said probe means includes a probe member having an operating end and being connected to the transducer for vibration and further including a shaft means through which said probe member passes, said shaft member being supported by the transducer.
Claim 4
Dependent Claim
39 words
A device as defined in claim 2 wherein said shaft includes an inlet and an outlet for circulating water around the probe member and means for conducting light from a cystoscope to the operating end of the vibrating probe.
Claim 5
Dependent Claim
69 words
A device as defined in claim 2 wherein said interconnecting means includes retaining means attached to the transducer outside the vibration effects of the transducer and a cone mounted on the retaining means, said cone being adapted to carry the shaft means which houses the probe member and is further adapted to carry a cystoscope so that the operating end of the probe member may be viewed during operation.
Claim 6
Dependent Claim
60 words
A device as defined in claim 1 wherein said mechanical means includes a bolt member passing through the base member, piezoelectric discs and sound transmitting member, said bolt member firmly holding the members and discs of the transducer from each end of the transducer, said interconnecting means including means for transmitting vibrations from the bolt member to the probe means.
Claim 7
Dependent Claim
65 words
A device as defined in claim 5 wherein said probe means includes a probe member and said probe interconnecting means includes a tapered Sound transmitting end portion having a free end and being formed on the bolt member as a one-piece configuration, said end portion being threadedly engaged with said probe member so that ultrasonic vibrations are transmitted from the transducer via the end portion.
Claim 8
Dependent Claim
47 words
A device as defined in claim 6 wherein a nut is fixedly tightened against the outside of the base member of the transducer, and the bolt member is in threaded engagement with said sound transmitting member of the transducer and is in threaded engagement with said nut.
Claim 9
Dependent Claim
56 words
A device as defined in claim 6 wherein the sound transmitting end portion of the bolt member tapers exponentially to its free end from the sound transmitting member of the transducer, runs in the form of an arc to a straight end having an inside thread, said probe member being threadedly engaged with said inside thread.
Claim 10
Dependent Claim
46 words
A device as defined in claim 6 wherein said probe member is developed cylindrically beyond the end of its threaded engagement with the vibration transmitting end portion of the one-piece bolt and then tapers conically and flares at its free end into a cup-shaped crushing end.
Claim 11
Dependent Claim
35 words
A device as defined in claim 1 wherein said probe means includes a hollow probe member having a hose connection for rinsing water to be conducted through the probe member to the operating end thereof.
Claim 12
Dependent Claim
69 words
A device as defined in claim 10 wherein said interconnecting means includes retaining means attached to the transducer outside the vibration effects of the transducer and a cone mounted on the retaining means, said cone being adapted to carry the shaft means which houses the probe member and is further adapted to carry a cystoscope so that the operating end of the probe member may be viewed during operation.
