ABSTRACT:
A handle assembly of a medical instrument has a handle with an axis extending from a proximal end of the instrument toward a distal end thereof; and an electrical circuit incorporated at least partially in the handle for controlling an application of an action to a patient via the medical instrument. The circuit has a first electrical contact and a second electrical contact each projecting from a surface of the handle. The electrical contacts are spaced from one another. An actuator ring is slidably disposed on the handle and surrounding the same for motion in alternately opposite directions along the handle under the control of an operator. A bridging electrical contact is disposed on the ring for conductively connecting the first and second electrical contacts at a first predetermined longitudinal position of the ring along the handle, thereby closing the circuit at that position of the ring, and for opening the circuit at another longitudinal position of the ring along the handle. Although the invention has been described in terms of particular embodiments and applications, one of ordinary skill in the art, in light of this teaching, can generate additional embodiments and modifications without departing from the spirit of or exceeding the scope of the claimed invention. Accordingly, it is to be understood that the drawings and descriptions herein are proffered by way of example to facilitate comprehension of the invention and should not be construed to limit the scope thereof.
