    • An endoscopic surgical instrument includes a housing, single access conduit formed in the housing, an irrigation port and an evacuation port, each port being connected through independent valves to the single access conduit. The single access conduit has a first end and a second end which is terminated in an aperture formed in the housing. A closure is provided for the aperture. A viewing device, such as an endoscope, is insertable through the aperture and the single access conduit, and is extended slightly beyond the first end. An electrode assembly having two or more retractable RF electrodes spaced a predetermined distance and angle apart, is also insertable through the aperture and the single access conduit, and is extendable beyond the first end. Each RF electrode is in electrical communication with a means for supplying R.F. energy and for continuously measuring impedance across the electrodes. Also, each RF electrode is extendable beyond and completely retractable into a guiding sheath. Each RF electrode is extendable beyond its guiding sheath by a predetermined length. Also, each RF electrode may be extended in such a manner to form a predetermined angular value with the longitudinal centerline of the single access conduit.
    • 内窥镜手术器械包括壳体,形成在壳体中的单通道导管,冲洗口和排气口,每个端口通过独立的阀连接到单个通路导管。 单个进入管道具有第一端和第二端,其端接在形成在壳体中的孔中。 为孔径提供闭合件。 诸如内窥镜的观察装置可以通过孔和单个通路导管插入,并且稍微延伸超过第一端。 具有间隔预定距离和角度分开的两个或更多个可伸缩RF电极的电极组件也可插入通过孔和单个通路导管,并且可延伸超过第一端。 每个RF电极与用于供应R.F.的装置电连通。 能量和连续测量电极两端的阻抗。 此外,每个RF电极可延伸超过并完全缩回到引导护套中。 每个RF电极可以超过其引导护套延伸预定长度。 此外,每个RF电极可以以与单个存取导管的纵向中心线形成预定角度值的方式延伸。
