    Abstract: A robotic surgical instrument includes a housing, a support plate disposed within the housing, and a shaft having a proximal end portion coupled to the support plate within the housing, a proximal segment, a distal segment, and an articulating portion interconnecting the proximal and distal segments. An end effector assembly is coupled to the distal segment of the shaft. A plurality of actuation components extends through the support plate and at least a portion of the shaft to operably couple to at least one of the end effector assembly, the articulating portion, or the distal segment to enable selective actuation of the end effector assembly. A seal configuration establishes seals against an interior annular surface of the shaft, about each actuation component of the plurality of actuation components, and within the proximal end portion of the shaft to inhibit fluid communication from the shaft into the housing.

    Abstract: A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

    Abstract: A surgical instrument includes an end effector assembly and a switch assembly. The end effector assembly includes a monopolar assembly and a bipolar assembly. The switch assembly includes first and second bipolar inputs, first and second bipolar outputs, a monopolar input, and a monopolar output. The switch assembly is transitionable between a first condition, wherein the first and second bipolar inputs are coupled to the first and second bipolar outputs, respectively, for supplying energy to the bipolar assembly, and a second condition, wherein the monopolar input and the monopolar output are coupled to one another for supplying energy to the monopolar assembly.

    Abstract: An endoscopic forceps includes an elongate shaft defining an instrument axis. An end effector includes first and second jaw members each supporting an opposed sealing surface for clamping tissue. At least one of the jaw members is movable relative to the instrument axis such that the jaw members are movable between a first spaced-apart configuration and a second closed configuration for grasping tissue. A cutting instrument includes a reciprocating blade translatable relative to the sealing surfaces to sever tissue clamped between the jaw members. The reciprocating blade contacts an undersurface of at least one of the jaw members when the jaw members are in the second configuration to define a gap distance between the sealing surfaces. A handle adjacent the proximal end of the elongate shaft is operable to induce motion in the jaw members, and an actuator is operable to selectively translate the reciprocating blade.

    Abstract: A method includes providing a bipolar energy source, a monopolar energy source, a bipolar assembly, and a monopolar assembly. The method further includes moving the monopolar assembly to a retracted position. Moving the monopolar assembly to the retracted position couples the bipolar energy source to the bipolar assembly and decouples the monopolar energy source from the monopolar assembly. The method further includes moving the monopolar assembly to a deployed position. Moving the monopolar assembly to the deployed position decouples the bipolar energy source from the bipolar assembly and couples the monopolar energy source to the monopolar assembly.

    Abstract translation: 钳子包括端部执行器组件，其在至少一个钳口构件内具有止动件和多个包覆成型的齿。 钳口构件中的一个（或两个）可相对于另一个在间隔开的位置和近似位置之间移动，以便抓住其间的组织。 一个（或两个）钳口构件包括在绝缘壳体内模制的止动件，以及具有由塑料形成的包覆成型齿的绝缘板。 包覆成型的牙齿延伸穿过密封板内的开口并突出穿过密封板的组织密封表面。 该止挡件主要通过承受大部分施加的载荷来控制相对的夹爪构件之间的间隙距离，并且包覆成型的齿通过承受剩余的施加载荷来辅助控制间隙距离。
