摘要：
An electrosurgical device capable of both: (i) generating a radiative microwave field to perform either blood coagulation or sterilization, and (ii) dispensing a liquid to a target area, e.g. adrenaline for the treatment of peptic ulcers. Using microwave energy allows controlled coagulation which is unaffected by changes in tissue impedance during coagulation, and which can achieve a high level of coagulation within a given time. The device comprises a probe tip having a coaxial transmission line that includes a hollow inner conductor having a dielectric material formed on an inner surface thereof. A liquid-conveying channel is located inside the dielectric material. The probe tip includes a conductive element coupled to receive microwave energy from the, coaxial transmission line, the conductive element forming a radiating antenna structure for emitting a microwave EM field outwardly from the probe tip.
