    摘要： An ablation instrument having an ergonomic handle that includes an actuator adapted to selectively extend and retract a blade that is pivotably mounted within an aperture assembly coupled to the housing by a shaft. The shaft extends distally from the handle and includes a coaxial feedline, a wire conduit disposed along a longitudinal axis of the shaft, and a pull wire disposed within the wire conduit and having a proximal and a distal end, wherein a proximal end of the pull wire is operably coupled to the actuator. The aperture assembly is coupled to a distal end of the shaft and includes a reflector having a closed upper portion, and an open lower portion from which the blade may be extended for use. Also disclosed is an ablation system that includes the above-described ablation instrument, a source of ablation energy, and optionally, a source of coolant for cooling the shaft and aperture assembly.

    摘要： A tissue dissector is provided. The tissue dissector includes a cannula and an introducer coaxially coupled to the cannula and movable therein from a retracted position to an extended position. An introducer is coaxially coupleable to the cannula and movable therein from a retracted position to an extended position. The introducer including a generally annular lumen disposed in fluid communication with an inflation port operably disposed on the introducer and in fluid communication with an inflatable balloon that couples to the introducer. The inflatable balloon is movable from a deflated condition for positioning the introducer adjacent target tissue, to an inflated condition for separating the target tissue from nearby tissue and for providing a barrier therebetween such that the nearby tissue is not affected during the electrosurgical procedure.

    摘要： An electrosurgical instrument is provided and includes a housing configured to connect to a source of bipolar electrosurgical energy and an electrode body coupled to the elongated housing. The electrode body includes an electrode face, first and second bipolar electrodes and a blade. The electrode face is formed on the distal end of the electrode body and includes a longitudinal axis and a transverse axis therethrough. The first and second electrodes have a leading edge and a trailing edge, are formed on opposite sides of the longitudinal axis and connect to opposed electrical potentials. The blade is positioned between the electrodes with at least a portion of the blade extending beyond the electrode face.

    摘要： An electrosurgical instrument is provided and includes an elongated housing having proximal and distal ends. The proximal end configured to couple to a source of electrosurgical energy via first and second channels extending along a length of the housing to the distal end thereof. The distal end including a reflector having a dielectric load operably coupled thereto and configured to receive at least a portion of the first conductor therein. In a first mode of operation, electrosurgical energy is transmitted to the first channel and reflected from the reflector to electrosurgically treat tissue. The reflector is configured to receive at least a portion of the second channel therein. In a second mode of operation, electrosurgical energy transmitted to the second channel to dissect tissue.
