Abstract

Diagnostic and/or therapeutic tool with spaced electrode probe assemblies and piezoelectric element generating electric pulse.

Claims

1. A diagnostic and therapeutic tool comprising a portable body assembly adapted for hand manipulation, a first electrode probe assembly mounted on said body assembly terminating in an electrically conductive probe tip disposed outside the body assembly, a second electrode probe assembly mounted on said body assembly terminating in an electrically conductive probe tip disposed outside the body assembly, a piezoelectric element mounted in said body assembly and means electrically connecting the probe tips of the first and second electrode probe assemblies to opposite poles of said piezoelectric element, and trigger actuated means for mechanically stressing the piezoelectric element to generate a voltage in the piezoelectric element which appears directly across said tips.

2. The tool of claim 1, wherein one of said electrode probe assemblies includes an elongated flexible reach of conductor cable flexibly connecting the conductive probe tip of the probe assembly and said body assembly whereby the probe tip is infinitely adjustable in position at a region remote from said body assembly.

3. The tool of claim 2, wherein the flexible reach of conductor cable is connected to said body assembly through a plug and jack connection.

4. The tool of claim 2, wherein said one of said electrode probe assemblies is electrically connected to the negative pole of said piezoelectric element.

5. A diagnostic and therapeutic tool comprising a hand gripped body housing including a finger actuated trigger element movably mounted on said body housing, a piezoelectric element housed within said housing, a jack exposed to one side of said housing electrically connected to the negative pole of said piezoelectric element, a rigid probe assembly extending outwardly from said housing having a conductive probe tip outside of said housing electrically connected to the positive pole of said piezoelectric element, a second probe assembly including a flexible conductor cable terminating at one end in a plug detachably fitting within said jack and terminating at its other end in an electrically conductive probe tip which tip through the cable and said plug and jack connection is electrically connected to the negative pole of the piezoelectric element, and means actuated by said trigger element for mechanically stressing the piezoelectric element to generate a voltage in the piezoelectric element which appears directly across said tips.
