An electrosurgical instrument for use in minimally invasive surgical techniques that provides a small scale localized microwave field capable of precisely ablating tissue, e.g. in the lungs, through suitable selection of geometry and material for a radiating distal tip thereof. The instrument may be used with a bronchoscope having a power delivery structure formed within the instrument cord thereof. A vision system may be incorporated into the energy delivery structure. The instrument comprise a coaxial cable for conveying microwave energy to a radiating tip portion that comprises a dielectric tip and a distal conductive portion that extends longitudinally therein. The dielectric tip has a dielectric constant greater than a dielectric material within the coaxial cable. The distal end of the device is designed to facilitate efficient microwave energy delivery into lung tumour tissue to achieve a localized volume of ablation.

Electrosurgical probe for delivering microwave energy

An electrosurgical device that is capable of both generating a plasma to perform surface coagulation and emitting a non-ionising microwave field (in the absence of plasma) to perform coagulation at a deeper level. The device comprises a probe tip that is connected to receive radiofrequency (RF) and/or microwave frequency energy from a generator, and also defines a flow path for a gas. The probe tip is adjustable between a first configuration, in which it defines a bipolar (e.g. coaxial) structure to produce a high electric field from the received RF and/or microwave frequency energy across the flow path for the gas to strike and sustain plasma and a second configuration, in which it defines an antenna structure to emit non-ionising microwave energy into tissue.
