Abstract
Abstract A disposable electro-surgical cutting and cauterizing tool is provided as a hand held tool for regulating the applications of electric power impulses or signals to an electro-surgical electrode. Cutting and coagulation signals can be selectively applied by the actuation of switches in a handle supporting the electrode. The handle of the tool is shaped to comfortably conform to the human hand and contains an index finger operated tactile switch for actuating the tool in either a cutting or coagulation mode of operation. The tool is made simple and inexpensive and is sterilized during packaging. It is disposable so that re-sterilization expenses are avoided. A reversible tip is provided to permit the user to select the best operating tool.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A disposable electro-surgical cutting and cauterizing tool comprising an electrode holder of elongate configuration, -having openings at opposite ends thereof; an electrical cord having one end extending through one end of the electrode holder and into the holder; a pair of spaced apart normally biased off electrical switch means projecting through a top surface of the electrode holder adjacent to other end of the holder; an electrode electrically connected to the electrical cord and to the switch means and projecting from the other end of the holder; and a flat connector at the other end of the cord, said connector having connector pins projecting from one edge of the connector and means connecting the other end of the cord into the connector at an opposite edge thereof.
Claim 2
Dependent Claim
127 words
A disposable electro-surgical cutting and cauterizing tool comprising an electrode holder of elongate configuration, -having openings at opposite ends thereof; an electrical cord having one end extending through one end of the electrode holder and into the holder; a pair of spaced apart normally biased off electrical switch means projecting through a top surface of the electrode holder adjacent to other end of the holder; an electrode electrically connected to the electrical cord and to the switch means and projecting from the other end of the holder; and a flat connector at the other end of the cord, said connector having connector pins projecting from one edge of the connector and means connecting the other end of the cord into the connector at an opposite edge thereof.
Claim 3
Dependent Claim
43 words
A disposable electro-surgical tool as in claim 1, wherein the switch means each include a membrane switch and a push button resting on the membrane switch and the electrode holder has a platform thereon to position the membrane switches beneath the push buttons.
Claim 4
Dependent Claim
44 words
A disposable electro-surgical tool as in claim 1 or 2,further including an electrically conductive socket in the holder, said socket being connected to the electrical cord and receiving one end of the electrode, and means in the holder for preventing rotation of the electrode.
Claim 5
Dependent Claim
32 words
A disposable electro-surgical tool as in any of the preceding claims, wherein the end of the electrode remote from the holder is angled with respect to the longitudinal axis of the holder.
Claim 6
Dependent Claim
30 words
A disposable electro-surgical tool as in any of the preceding claims, wherein the electrode holder has a pencil-like configuration and is tapered from the top surface to a bottom surface.
Claim 7
Dependent Claim
38 words
A disposable electro-surgical tool as in any of the preceding claims, wherein the end of the cord extends into the connector parallel to a slot extending to near the mid-point of the connector along the opposite edge thereof.
Claim 8
Dependent Claim
30 words
A disposable electro-surgical tool as in any of the preceding claims, wherein the electrode is reversible in the holder to present for use, a pair of differently shaped surgical tools.
Claim 9
Dependent Claim
16 words
A disposable electro-surgical tool, substantially as previously described with reference to the figures of enclosed drawing.
Claim 10
Dependent Claim
16 words
A disposable electro-surgical tool, substantially as previously described with reference to the figures of enclosed drawing.
