Abstract
Various embodiments provide an electrosurgical system for treating biological tissue. The system comprises: an electrosurgical generator configured to supply pulsed microwave energy; and an electrosurgical instrument. The electrosurgical instrument comprises a flexible coaxial cable arranged to convey the pulsed microwave energy; and a radiating tip portion connected at a distal end of the coaxial cable and configured to receive the pulsed microwave energy. The radiating tip portion has a maximum outer diameter that is 1.0 mm or less, and wherein the maximum outer diameter of the radiating tip portion is smaller than an outer diameter of the coaxial cable. Also, the radiating tip portion comprises: a proximal coaxial transmission line for conveying the pulsed microwave energy; and a distal needle tip mounted at a distal end of the proximal coaxial transmission line, the distal needle tip being arranged to deliver the pulsed microwave energy into biological tissue.
