Abstract: An aspirator attachment (10) for an electrosurgical pencil (11) has an axis and an electrode (12) at a distal end (13) thereof to transmit vacuum to remove fluid from an operative site. A semi-rigid hollow body (14) extends parallel to the axis and is contoured to fit coextensively against the elongate pencil. A body passage (15) has an opening (16) at its distal part (17) that is about the electrode (12) and facing toward the patient. The part conjugates aft of the electrode (12) for generally fluid tight pencil engagement. The opening (16) is scalloped with opposed edges increasing visibility, decreasing tissue trapping and decreasing electrode (12) temperature. A part port (21) between the conjugating end (18) and its opening (16) communicates with the passage (15) and the opening (16). A connector (22) at the body end opposite the opening (16) is shaped for fluid communication with the passage (15) and vacuum. A body center section, between the port (21) and the connector (22) joins them. An offset transition (27) of the body, adjacent the pencil conjugating end (18), has the passage (15) therethrough for connecting the port (21) and the center section and alignment. The passage (15) has a uniform cross sectional area extending therein. A swivel (23) attached to the connector (22) permits relative rotation between the pencil and a vacuum hose. The center section at the connector (22) has a rib (24) to engage the pencil retaining the opening (16) about the distal end (13) and resisting movement. The passage (15) within the center section has a generally D shaped cross section. The pencil has controls along a side thereof and the body mates with the pencil opposite the controls. Methods of combining and using the pencil and aspirator include steps of engaging and nesting them together.

Abstract translation: 用于电外科手术铅笔（11）的抽吸器附件（10）具有在其远端（13）处的轴线和电极（12），以透射真空以从手术部位移除流体。 半刚性中空主体（14）平行于轴线延伸并且被成形为与伸长的铅笔共同配合。 身体通道（15）在其远端部分（17）处具有围绕电极（12）并面向患者的开口（16）。 所述部件将电极（12）的后部共轭，用于大体上流体密封的铅笔接合。 开口（16）扇形化，具有相对边缘，增加可见度，减少组织捕获和降低电极（12）的温度。 共轭端（18）与其开口（16）之间的部分端口（21）与通道（15）和开口（16）连通。 在与开口（16）相对的主体端部处的连接器（22）成形为用于与通道（15）和真空流体连通。 在端口（21）和连接器（22）之间的身体中心部分连接它们。 与铅笔共轭端（18）相邻的本体的偏移转变（27）具有用于连接端口（21）和中心部分并对准的通道（15）。 通道（15）具有在其中延伸的均匀横截面积。 附接到连接器（22）的旋转件（23）允许铅笔和真空软管之间的相对旋转。 连接器（22）的中心部分具有肋（24），用于接合围绕远端（13）保持开口（16）并抵抗运动的铅笔。 中心部分内的通道（15）具有大致D形的横截面。 铅笔沿其一侧具有控制，并且身体与与控件相对的铅笔相配合。 组合和使用铅笔和抽吸器的方法包括将它们接合并嵌套在一起的步骤。
