Claims

WHAT IS CLAIMED IS:

1. An electrical stimulation device comprising: a handle including: a proximal end; a distal end; one or more actuators; and a display; and a probe attached to and extending from the distal end of the handle, the probe including a stimulation portion and a return portion, wherein a spacing between the stimulation portion and the return portion is adjustable.

2. The electrical stimulation device of claim 1 , wherein each of the stimulation portion and the return portion of the probe is a lead, and together, the leads form a single probe.

3. The electrical stimulation device of claim 1 , wherein the probe is formed by the stimulation portion as a stimulation probe and the return portion as a return probe, and together, the probes form a double probe.

4. The electrical stimulation device of claim 1 , wherein the stimulation portion and the return portion of the probe extend from the distal end of the handle parallel to one another.

5. The electrical stimulation device of claim 1 , wherein the probe is interchangeable.

6. The electrical stimulation device of claim 5, wherein the handle includes a release button configured to detach the interchangeable probe.

7. The electrical stimulation device of claim 1 , wherein the probe is a forceps probe attached to and extending from the distal end of the handle, the forceps probe functioning as a forceps.

8. The electrical stimulation device of claim 1 , wherein the one or more actuators includes a slider, and movement of the slider causes the spacing between the stimulation portion and the return portion of the probe to change.

9. The electrical stimulation device of claim 1 , wherein the one or more actuators includes a slider, and movement of the slider causes a change in one or more of: a pulse width; a current amplitude; or a frequency, of the electricity supplied to the stimulation portion.

10. The electrical stimulation device of claim 1 , wherein the stimulation portion and the return portion of the probe are concentric.11 . The electrical stimulation device of claim 1 , wherein the probe further includes an insulator portion provided between at least a portion of the stimulation portion and at least a portion of the return portion.

12. The electrical stimulation device of claim 1 , wherein the device is capable of providing both: monophasic stimulation in which the stimulation portion acts only stimulation probe and the return portion acts only as a return probe; and biphasic stimulation in which the stimulation portion and return portion each act as stimulation and return probes in an alternating manner.

13. The electrical stimulation device of claim 1 , wherein the device is configured to provide one or more of tactile feedback, auditory feedback, or visual feedback to a user.

14. The electrical stimulation device of claim 13, wherein the device is configured to provide tactile feedback as a vibration.

15. The electrical stimulation device of claim 1 , wherein the one or more actuators include a button that, when depressed, causes the generation of one or more stimulation pulses.

16. The electrical stimulation device of claim 1 , wherein the one or more actuators includes a set of control buttons configured to receive an input value to increase or decrease value by a predetermined amount, the input value being one of: a pulse width; a current amplitude; or a frequency;of the electricity supplied to the stimulation portion.

17. The electrical stimulation device of claim 1 , wherein the display is a liquid crystal display (LCD).

18. The electrical stimulation device of claim 1 , wherein the device is configured for use in one or more of the following: locating one or more nerves; identifying one or more nerves, including identifying one or more of motor nerves and sensory nerves; stimulating regeneration of one or more nerves; providing a nerve block to one or more nerves; and managing and relieving nerve pain.
