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 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。
