    • An open electrosurgical forceps for sealing tissue includes a pair of first and second shaft members each having a jaw member disposed at a distal end thereof. The jaw members are movable from a first position in spaced relation relative to one another to a subsequent position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members includes an electrically conductive sealing plate for communicating electrosurgical energy through tissue held therebetween. At least one of the jaw members includes a cutting slot defined along a length thereof which is dimensioned to reciprocate a cutting instrument therealong for cutting tissue disposed between jaw members. An actuator advances the cutting instrument from a first position wherein the cutting instrument is disposed proximal to tissue held between the jaw members to at least one subsequent position wherein the cutting instrument is disposed distal to tissue held between the jaw members.
    • 用于密封组织的开放的电外科钳包括一对第一和第二轴构件,每个第一和第二轴构件具有设置在其远端处的钳口构件。 钳口构件可以从相对于彼此间隔开的第一位置移动到随后的位置,其中钳口构件协作以在其间抓握组织。 每个钳口构件包括用于通过保持在其间的组织传导电外科能量的导电密封板。 钳口构件中的至少一个包括沿着其长度限定的切割槽,其尺寸被设计成使切割器具沿其往复运动,用于切割设置在钳口构件之间的组织。 致动器将切割仪器从第一位置推进,其中切割器械靠近保持在钳口构件之间的组织设置在至少一个随后的位置,其中切割器械设置在夹持在钳口构件之间的组织的远侧。

    • A catheter syste includes a handle and a catheter component operatively connected to the handle for selective adjustment by an actuator associated with the handle housing. The actuator comprises at least in part a generally cylindrical shuttle disposed at least in part within the housing for longitudinal movement. The catheter component is operatively coupled to the shuttle for movement therewith. The shuttle has an outer surface with an annular groove formed therein, and an elastomeric ring seated in the annular groove. An annular slide bearing is retained in the housing, with the shuttle being in part disposed in the annular groove and with the elastomeric ring in frictional contact with the slide bearing. Friction between the elastomeric ring and the slide bearing is sufficient to frictionally the shuttle at a selected longitudinal position relative to the housing corresponding to a selected adjustment of the catheter component.
    • 导管系统包括手柄和可操作地连接到手柄的导管部件,以通过与手柄壳体相关联的致动器进行选择性调节。 该致动器至少部分地包括至少部分地设置在壳体内用于纵向移动的大致圆柱形的梭。 导管部件可操作地联接至梭子以随其移动。 梭子具有在其中形成有环形凹槽的外表面以及位于环形凹槽中的弹性环。 环形滑动轴承保持在壳体中,梭子部分地设置在环形槽中并且弹性环与滑动轴承摩擦接触。 弹性环与滑动轴承之间的摩擦足以使滑梭在选定的纵向位置处相对于壳体摩擦,对应于导管部件的选定调整。
