An electrosurgical resector tool having an energy delivery structure that provides a plurality of operational modalities that facilitate biological tissue cutting and sealing using radiofrequency (RF) electromagnetic (EM) energy and/or microwave EM energy. The tool comprises a static first blade element, and a pivotable second blade element that has a length commensurate with the first blade element whereby, in a closed position, it lies adjacent to a laterally facing surface of the first blade element. The blade elements constitute an energy delivery mechanisms that is compact enough to enable the tool to be insertable through an instrument channel of a surgical scoping device, such as an endoscope, gastroscope or bronchoscope.

Electrosurgical resector tool

An electrosurgical apparatus and method for performing thermal treatment in the gastrointestinal tract, e.g. to ablate duodenal mucosal tissue. The apparatus comprises an instrument having a flexible cable and an applicator suitable for use with a gastroscope, which can be deployed within a patient to delivery energy in a targeted or otherwise controllable manner. The applicator can deliver microwave energy by radiation. The direct and depth-limited nature of microwave energy can be make it more effective than treatments that rely on thermal conduction. The applicator may include a radially extendable portion arranged to move an microwave energy delivery structure into contact with duodenal mucosal tissue at the treatment region. The applicator may comprise any of a balloon, bipolar radiator, movable paddle, and rotatable roller element.

Electrosurgical apparatus and method

An electrosurgical apparatus comprising an electrosurgical forceps instrument that combines la robust jaw opening mechanism with an a microwave energy delivery mechanism. The instrument includes a rigid bracket mounted at a distal end of a flexible shaft, wherein a pair of jaws are pivotably mounted on the rigid bracket. The instrument includes an energy delivery structure comprising a flexible dielectric substrate having a first electrode and an second electrode formed on one of the pair of jaws, wherein the first electrode and the second electrode are arranged to emit microwave energy. The electrosurgical apparatus may also comprise a handpiece that combines rotation control of an electrosurgical instrument with both power delivery and end effector actuation (e.g. jaw closure, blade retraction or the like).

Electrosurgical apparatus

An electrosurgical vessel sealing device that can seal biological vessels using a confined microwave field that yields a well-defined seal location with low thermal margin. The device comprises a pair of jaws that are movable relative to each other to grip biological tissue. A blade for cutting the gripped tissue is slidable between the jaws. A coplanar microstrip antenna is mounted on the inner surface of one or both of the pair of jaws to emit microwave energy into the gap therebetween. The device may comprise a separate dissector element to enable fine tissue cutting and dissection to be performed.

Electrosurgical instrument

Sterilisation apparatus comprising a sterilisation instrument configured to be inserted through the instrument channel of a surgical scoping device and a withdrawal device for withdrawing the sterilisation instrument from the instrument channel at a predetermined rate. The sterilisation instrument comprises an elongate probe having a probe tip with a first electrode and a second electrode arranged to produce an electric field from received RF and/or microwave frequency EM energy. In operation the instrument may disinfect an inner surface of the instrument channel by emitting energy whilst being withdrawn through the channel.

Apparatus for sterilising an instrument channel of a surgical scoping device

Sterilization apparatus comprising a sterilization instrument configured to be inserted through the instrument channel of a surgical scoping device and a withdrawal device for withdrawing the sterilization instrument from the instrument channel at a predetermined rate. The sterilization instrument comprises an elongate probe having a probe tip with a first electrode and a second electrode arranged to produce an electric field from received RF and/or microwave frequency EM energy. In operation the instrument may disinfect an inner surface of the instrument channel by emitting energy while being withdrawn through the channel.
