    • An electrosurgical suction coagulator includes a housing having proximal and distal ends and a substantially malleable elongated tube-like shaft extending longitudinally from a distal end thereof. The elongated tube-like shaft includes a tube-like outer wall having a tube-like dielectric sheath at least partially disposed thereon. A tube-like electrode is disposed coaxially through the tube-like outer wall and is configured to operably couple to a source of electrosurgical energy. A distal end of the tube-like electrode protrudes at least partially from a distal end of the tube-like outer wall and the tube-like electrode has at the distal end thereof at least one aspiration port defined therein. The tube-like electrode is adapted at the proximal end thereof to operably couple to a source of suction. A vacuum space is disposed concentrically between the tube-like electrode and the tube-like outer wall to impede the propagation of thermal energy along the tube-like shaft.
    • 电外科吸入式凝结器包括具有近端和远端的壳体,以及从其远端纵向延伸的基本上可延展的细长管状轴。 细长管状轴包括具有至少部分地设置在其上的管状电介质护套的管状外壁。 管状电极通过管状外壁同轴设置,并且被配置为可操作地耦合到电外科能量源。 管状电极的远端至少部分地从管状外壁的远端突出,并且管状电极在其远端处具有限定在其中的至少一个抽吸端口。 管状电极在其近端处适于可操作地耦合到吸入源。 真空空间同心地设置在管状电极和管状外壁之间,以阻止热能沿着管状轴的传播。
