摘要：
An electrosurgical instrument which includes opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The instrument includes a housing and a pair of electrodes. Each electode preferably includes an electrically conductive surface (e.g., which can be dimensioned for sealing, clamping and/or cutting) and an insulating substrate which is dimensioned to be engageable with the end effectors such that the electrodes reside in opposing relation relative to one another. The dimensions of the insulating substrate are different from the dimensions of the electrically conductive surface to reduce thermal spread to adjacent tissue structures. The insulating substrate is made from a material having a Comparative Tracking Index of about 300 volts to about 600 volts to reduce the incidence of flashover.
摘要（中）：
一种电外科器械，其包括相对的末端执行器和用于实现末端执行器相对于彼此运动的手柄。 仪器包括壳体和一对电极。 每个电极优选地包括导电表面（例如，其尺寸可以用于密封，夹紧和/或切割）以及绝缘基板，该绝缘基板的尺寸被设计成可与末端执行器接合，使得电极相对于彼此处于相对关系 。 绝缘基板的尺寸不同于导电表面的尺寸，以减少热传播到相邻的组织结构。 绝缘衬底由具有约300伏至约600伏特的比较跟踪指数的材料制成，以减少闪络的发生率。
