Abstract
Embodiments of the invention provide a hollow cable for transmitting radiofrequency and/or microwave frequency energy to an electrosurgical instrument, wherein the hollow cable is provided with electrical connectors for forming a bipolar electrical connection with an electrosurgical instrument that fits within, e.g. slides relative to, the hollow cable. The connectors can be conductive protrusions extending in an axial direction on opposite sides of the cable. The protrusions can be tabs, fins, rods, pins, or wires. The protrusions can be strips which engage corresponding terminals on the instrument. The transmission line structure of the invention can have a greater diameter then convention coaxial cables, which can minimise loss whilst still providing access for control wires and/or fluid to reach an surgical instrument. The cable can be used with multiple instruments.
