摘要： A dipole microwave applicator emits microwave radiation into tissue to be treated. The applicator is formed from a thin coax cable having an inner conductor surrounded by an insulator, which is surrounded by an outer conductor. A portion of the inner conductor extends beyond the insulator and the outer conductor. A ferrule at the end of the outer conductor has a step and a sleeve that surrounds a portion of the extended inner conductor. A tuning washer is attached to the end of the extended inner conductor. A dielectric tip encloses the tuning washer, the extended inner conductor, and the sleeve of the ferrule. The sleeve of the ferrule and the extended inner conductor operate as the two arms of the dipole microwave antenna. The tuning washer faces the step in the ferrule, and is sized and shaped to cooperate with the step in balancing and tuning the applicator.

摘要： A radiation applicator with a dielectric body (2) surrounding the antenna. The dielectric body (2) is comprised of three sections (3, 4 and 5) with different dielectric constants to provide broad-band matching of the applicator to surrounding material. Washers (10) and (11) are mounted on the antenna to act as reflectors.

摘要： A microwave applicator having a probe which comprises an elongate shaft (14), the shaft having an external tubular wall (18), a radiating portion (15) disposed at the distal end of the shaft (14), a transmission line (17) extending to the radiating portion internally of the tubular external wall (18), and an elongate flow dividing member (19) which co-extends with the transmission line (17) longitudinally of the shaft (14), the side wall of the transmission line (17) and the side wall of the flow dividing member (19) contacting each other and contacting the internal surface of the external tubular wall (18) at two-spatially separated discrete positions, thereby defining a pair of flow channels (20, 21) inside the shaft (14). In use, cooling fluid can pass down one channel (20) and return via the other channel (21). The structure of the probe is uncomplicated and the probe is straightforward to assemble.

摘要： A microwave applicator device comprising a probe (11) for ablating the body of a human or animal, a cooling passage (20,21) extending through the probe (11) and arranged to carry a cooling fluid, a pump (71) for pumping the fluid through the probe (11), and an elongate flexible duct (104) extending between the pump (71) and one end of the cooling passage (20,21), the pump comprising a pump body (73) including a motor (120) and a pump head (72) detachably mounted to the pump body (73), the pump head (72) comprising a first port (86) connected to a proximal end of the elongate flow duct (104), a second port (85) and fluid propulsion means (84,92) for creating a flow of fluid between the ports (85,86) and along the elongate flow duct 104 upon energization of the motor (120), the pump head (72) being arranged to sealingly contain the fluid. The pump head (72), the elongate flexible duct (104) and the probe (11) form a replaceable assembly that can be detached from the pump body (73) and discarded following use.
