摘要： An electrosurgical unit for conducting a predetermined ionizable gas in a jet stream to the tissue at a predetermined flow rate sufficient to clear natural fluids from the tissue and to substantially expose the tissue stroma and for exposing the gas to an electrical radio frequency energy to ionize the gas in conductive pathways in the gas jet stream. The unit includes a nozzle which is releasably connected to a handle for easy manipulation by a surgeon with the nozzle including means for supporting an electrode in an optimal position for initiation of the ionization of the gas. Also, a connecting system is disclosed for connecting the hose on which the handle is mounted to a gas delivery apparatus and supply or electrical energy which permits the hose to rotate while maintaining a positive hermetic seal to prevent the hose from kinking during use by a surgeon.
摘要翻译：一种电外科单元，用于以预定的流速将喷射流中的预定可电离气体以预定的流速传导到组织中，该流速足以从组织中清除天然流体并基本上暴露组织基质，并将气体暴露于电射频能量以电离气体在气体射流中的导电通路中。该单元包括可释放地连接到手柄的喷嘴，以便外科医生易于操作，喷嘴包括用于将电极支撑在用于引发气体电离的最佳位置的装置。此外，公开了一种用于将其上安装有手柄的软管连接到气体输送装置的连接系统以及允许软管旋转同时保持正气密密封以防止软管在外科医生使用期间扭结的供应或电能。
