First Claim
Patent Images
1. A bipolar cable for a bipolar surgical instrument, comprising:
- a pair of parallel conductors, the conductors comprising an electrically conductive wire having an electrically insulating coating, each conductor having a length, a distal end and a proximal end, wherein the insulating coatings are separably connected to each other along substantially the entire lengths of the conductors wherein said conductors may be separated from each other along a length by pulling the distal ends of the conductors apart;
a grommet member slidably mounted on the conductors, said grommet member having an interior passage for receiving the conductors;
a spring-loaded electrical connector mounted to the distal end of each conductor;
a tubular electrically insulated member mounted over the spring-loaded connector; and
, a bipolar generator plug mounted to the proximal ends of the conductors for engagement with a bipolar electrosurgical generator said plug having a pair of electrically conductive mounting posts, wherein the length of the separation of the conductors may be changed by sliding the grommet along the conductors.

Abstract
An electrical connecting cable for bipolar electrosurgical scissors. The cable has a pair of insulated parallel conductors having insulating coatings. The coatings are separably connected. A slidable grommet is mounted to the cable. The conductors are partially separable from each other. A plug is mounted to one end of the cable. Spring loaded connectors are mounted to the other end of the cable.
