Abstract
Abstract An electrocautery hemostat is provided which may be used as a hemostatic clamping device and an apparatus for cauterizing bleeding blood vessels during surgery. The electrocautery hemostat is comprised of a pair of pivoted members which form at one end mating jaws for enabling the clamping of a bleeding blood vessel. The opposite ends of the members are provided with an insulative covering with at least one opening therethrough. An electrical switch is provided for clamping to one of the pivoted members and for making an electrical connection to the member through the opening in the insulative covering. The other end of the switch is connected through an electrical conductor to a source of electrical energy. The mating jaws are of a smaller cross-section than a conventional hemostat and are adapted for use in probing and cauterizing. The device of the present invention may be used by a surgeon with one hand, the other hand being free to perform other functions, both as a cauterizing instrument and to clamp, as may be necessary, a bleeding blood vessel in a manner similar to that of a hemostat.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
204 words
An electrocautery and hemostatic clamping device, comprising: a first and second pivoted members pivoted at a point between the ends of said members, said members being comprised of a conductive material; said first and second pivoted members being provided with mating jaws at one end, said mating jaws being of a cross-section adapted for probing during the performance of surgery; said first and second members being provided with handle means at a predetermined distance from the jaws and adjustable retaining means for retaining said jaws in a predetermined clamping position; an insulative covering applied over said first and second members extending substantially from the point of pivot to said handle means with at least one opening therethrough for an electrical connection to one of said members; and electrical switch means adapted to be releasably attached to one of said members, said electrical switch means being provided with means for being connected to an electrical source, said electrical switch means being provided with an electrical connector for connecting through said opening in said insulative covering of said member to which said electrical switch means is attached whereby through operation of said electrical switch means an electrical potential may be applied to said members for cauterizing.
Claim 2
Dependent Claim
204 words
An electrocautery and hemostatic clamping device, comprising: a first and second pivoted members pivoted at a point between the ends of said members, said members being comprised of a conductive material; said first and second pivoted members being provided with mating jaws at one end, said mating jaws being of a cross-section adapted for probing during the performance of surgery; said first and second members being provided with handle means at a predetermined distance from the jaws and adjustable retaining means for retaining said jaws in a predetermined clamping position; an insulative covering applied over said first and second members extending substantially from the point of pivot to said handle means with at least one opening therethrough for an electrical connection to one of said members; and electrical switch means adapted to be releasably attached to one of said members, said electrical switch means being provided with means for being connected to an electrical source, said electrical switch means being provided with an electrical connector for connecting through said opening in said insulative covering of said member to which said electrical switch means is attached whereby through operation of said electrical switch means an electrical potential may be applied to said members for cauterizing.
