Abstract
Abstract A hand operable bipolar forceps instrument comprising two interfacing pivotal blade member's which are each an electrode individually pivotable in relation to each other. Pivotal movement of the blades is effectuated by two respective electrically-conductive rigid rods, each coupled to a respective blade member, extending through an elongated tubular member having disposed at its proximal end a scissors type handle whose hand operation causes the blade members to pivot in relation to each other. The rods are connectable proximally to an energy source to thereby electrically activate the blade members.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
142 words
A hand operable bipolar forceps instrument comprising: (a) an elongated tubular member having a proximal end, a distal end, and a lumen extending therebetween; (b) two interfacing pivotable blade members disposed at the distal end of the tubular member, said blade members each being an electrode to which current can flow, and further wherein each blade member is individually pivotable in relation to the other blade member from an open position to a closed position; (c) a handle disposed at the proximal end of the tubular member, said handle being in communication with the blade members and being hand operable to thereby produce pivotal action of the blade members; and (d) means for journaling the proximal end of the elongated tubular member for rotation in the handle, rotation of the tubular member effecting rotation of the blade members relative to the handle.
Claim 2
Dependent Claim
142 words
A hand operable bipolar forceps instrument comprising: (a) an elongated tubular member having a proximal end, a distal end, and a lumen extending therebetween; (b) two interfacing pivotable blade members disposed at the distal end of the tubular member, said blade members each being an electrode to which current can flow, and further wherein each blade member is individually pivotable in relation to the other blade member from an open position to a closed position; (c) a handle disposed at the proximal end of the tubular member, said handle being in communication with the blade members and being hand operable to thereby produce pivotal action of the blade members; and (d) means for journaling the proximal end of the elongated tubular member for rotation in the handle, rotation of the tubular member effecting rotation of the blade members relative to the handle.
Claim 3
Dependent Claim
14 words
The instrument as claimed in claim 1 wherein each blade member is a metal.
Claim 4
Dependent Claim
13 words
The instrument as claimed in claim 2 wherein the metal is stainless steel.
