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.

摘要： Embodiments of the invention provide a surgical snare structure in which the material used for the snare and the deployment mechanism of the snare are configured to improve the cutting efficacy of the snare. In particular, the surgical snare structure of the invention may omit the kink or nib present in the loop of known surgical snares and/or may provide a reaction surface against which the cutting action of the snare is effective. The surgical snare of the invention may be a cold, i.e. mechanical-only effect, snare, or may be used in conjunction with radiofrequency (RF) and/or microwave energy to enhance a cutting or coagulation effect.

摘要： A biopsy forceps tool (preferably for endoscopic use) in which microwave energy is used to coagulate bleeding after a biological tissue sample is collected between a pair of jaws. The pair of jaws define an enclosure that is isolated from the microwave energy itself and insulated from any thermal changes that occur due to application of the microwave energy. The tool comprises a pair of jaws connected to a coaxial cable, each of the pair of jaws comprising an electrically conductive shell, the jaw assembly being movable between a closed position in which the electrically conductive shells enclose an internal volume for holding a tissue sample and an open position in which the internal volume is exposed in order to receive the tissue sample. The electrically conductive shells form a Faraday cage around the internal volume when in the closed position.

摘要： 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.

摘要： An electrosurgical snare (500), e.g. suitably sized for insertion down the instrument channel of an endoscope, arranged to radiate microwave frequency energy (e.g. having a frequency greater than 1 GHz) from an elongate conductive element (122) within an area encircled by a retractable loop (118). The elongate conductive element (122) and retractable loop (118) may be independently slidable relative to a snare base (512) at a distal end of a sleeve (114) to provide an appropriate device configuration. By controlling the shape of the emitted microwave field, the risk of collateral thermal damage can be reduced.
