具有可移除的构件的外科器械
摘要：
本发明公开了一种包括联接至电外科能量源的把手的外科器械。一对相对的爪构件操作地联接至所述把手的远侧端部，以使得所述爪构件按照选择在打开位置和闭合位置之间运动。支撑于所述爪构件中的一个上的基座包括机械配合特征和与电外科能量源电连通的导电区域。能按照选择移除的封闭板包括互补地接合的机械配合特征和导电区域，所述导电区域被设置为在基座的机械配合特征和封闭板的机械配合特征接合时接触所述基座的导电区域。所述互补地接合的机械配合特征包括一对相间隔的凸起以及一对相间隔的凹槽，所述凹槽向基座或封闭板的相对的侧开放，以使得能将封闭板扭转至基座上。
摘要（英）：

An end effector, comprising: a pair of opposed jaw members; a base supported on at least one of the pair of opposed jaw members, the base having an electrically conductive region; a seal plate supported on the base and including a seal surface, the seal plate defining a bore that extends through the seal surface; and at least one protrusion constructed of an electrically isolative material and extending upwardly from the base, through the bore of the seal plate, and beyond the seal surface of the seal plate such that the at least one protrusion maintains a gap between the pair of opposed jaw members when the pair of opposed jaw members are moved to a closed position.
