Abstract
Abstract The present invention provides a bipolar surgical instrument 10 comprising a handle portion 20, a tool portion 60 for applying electrical energy to tissue cooperating with the handle portion for movement between an open and closed position, electrical connection means 80 for connecting the tool portion to a source of electrical energy having receptacles 82 for receiving the electrical energy combined with an elongated conductor 86 for transmitting electrical energy to the tool portion, the elongated conductor having first and second conducting paths 87 electrically isolated from one another. The instrument has particular application to endoscopic and laparoscopic surgical procedures.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
119 words
A bipolar surgical instrument comprising: at least one handle; tool means; movable means extending between said at least one handle and said tool means, said movable means being movable in response to movement of said at least one handle for movement of said tool means between an electrically inactive open position and a closed positions to apply electrical energy to tissue; and electrical connection means for connecting said tool means to a source of electrical energy, said electrical connection means having means for receiving said electrical energy, an elongate conductor member cooperating therewith for transmitting said electrical energy, said elongate conductor member comprising at least one insulating member upon which first and second electrically isolated conducting paths are disposed.
Claim 2
Dependent Claim
33 words
An instrument as claimed in claim 1 wherein said tool means comprises forceps having first and second legs, each leg constituting an electrode and having means for gripping tissue adjacent its distal end.
Claim 3
Dependent Claim
31 words
An instrument as claimed in claim 2 wherein said first forcep leg electrically communicates with said first conducting path and said second forcep leg electrically communicates with said second conducting path.
Claim 4
Dependent Claim
27 words
An instrument as claimed in claim 1 wherein said tool means comprises jaw members for gripping tissue, having first and second jaws, each jaw constituting an electrode.
Claim 5
Dependent Claim
29 words
An instrument as claimed in claim 4 wherein said first jaw electrically communicates with said first conducting path and said second jaw electrically communicates with said second conducting path.
Claim 6
Dependent Claim
26 words
An instrument as claimed in any one of the preceding claims wherein said elongate conductor member comprises a printed circuit having first and second conducting paths.
Claim 7
Dependent Claim
19 words
An instrument as claimed in any one of the preceding claims wherein said movable means comprises a slidable sleeve.
Claim 8
Dependent Claim
23 words
An instrument as claimed in claim 7 wherein said slidable sleeve comprises an elongate tubular member adapted for use in non-invasive surgical procedures.
Claim 9
Dependent Claim
16 words
An instrument as claimed in claim 8 including a gaseous seal disposed within the tubular member.
Claim 10
Dependent Claim
21 words
An instrument as claimed in claim 8 or 9 wherein said elongate conductive member extends longitudinally within said elongate tubular member.
Claim 11
Dependent Claim
55 words
An instrument as claimed in claim 7, 8, 9 or 10 wherein said at least one handle comprises an actuating handle pivotally mounted to a handle body, said actuating handle having means to engage said slidable sleeve whereby pivotal movement of said actuating handle produces longitudinal movement of said sleeve between open and closed positions.
Claim 12
Dependent Claim
47 words
An instrument as claimed in any one of claims 7 to 11, wherein said slidable sleeve includes a distal camming portion adapted to engage angled camming surfaces for aiding in the opening and closing of said forceps in response to movement of said at least one handle.
Claim 13
Dependent Claim
21 words
An instrument as claimed in any one of the preceding claims wherein the tool means comprise projections having angled camming surfaces.
Claim 14
Dependent Claim
40 words
An instrument as claimed in any of the preceding claims wherein said electrical connection means further comprises contact springs extending from said means for receiving electrical energy for connecting said elongate conductor means to said means for receiving electrical energy.
Claim 15
Dependent Claim
31 words
An instrument as claimed in any one of the preceding claims wherein said means for receiving electrical energy comprises a pair of receptacles adapted to connect to an r.f. power supply.
Claim 16
Dependent Claim
89 words
A bipolar surgical instrument comprising: an elongate tubular member; at least one handle extending from said tubular member; tool means at least partially disposed within said tubular member and extending from a distal end thereof, wherein movement of said at least one handle moves said tool means between open and closed positions; and elongate conductive means extending longitudinally within said elongate tubular member and having a proximal end for receiving electrical energy from an electrical energy source, said conductive means being positioned at least partially between said tool means.
Claim 17
Dependent Claim
31 words
An instrument as claimed in claim 8 or 16 wherein said elongate conductive means is composed of an insulating central portion having first and second electrically isolated conducting paths disposed thereon.
Claim 18
Dependent Claim
23 words
An instrument as claimed in any one of the preceding claims, wherein said elongate conductive means is composed of a substantially rigid material.
Claim 19
Dependent Claim
19 words
An instrument as claimed in any one of the preceding claims, wherein said elongate conductive means is substantially planar.
