摘要： An endoscopic forceps includes a housing having a shaft attached thereto, the shaft including a pair of jaw members disposed at a distal end thereof. The forceps also includes a drive assembly disposed in the housing which moves the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for manipulating tissue. A pair of handles is operatively connected to the drive assembly and the handles are movable relative to the housing to actuate the drive assembly to move the jaw members. Each of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue. The forceps also includes a first switch disposed on the housing which is activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue in a monopolar fashion. A second switch is disposed on the housing and is activatable to selectively deliver energy of a first electrical potential to one jaw member and selectively deliver energy of a second electrical potential to the other jaw member for treating tissue in a bipolar fashion.

摘要翻译： 内窥镜钳包括具有附接到其上的轴的壳体，所述轴包括设置在其远端处的一对钳口构件。 镊子还包括设置在壳体中的驱动组件，其将钳口构件相对于彼此从第一位置移动，其中钳口构件相对于彼此以间隔开的关系设置到第二位置，其中钳口构件彼此更靠近 用于操纵组织。 一对把手可操作地连接到驱动组件，并且手柄相对于壳体可移动，以驱动驱动组件以移动钳口构件。 每个钳口构件适于连接到电能源，使得钳口构件能够传导用于治疗组织的能量。 镊子还包括设置在壳体上的第一开关，其可激活以将第一电位的能量选择性地传递到至少一个钳口构件，以以单极方式处理组织。 第二开关设置在壳体上并且可激活以将第一电势的能量选择性地传递到一个钳口构件，并且选择性地将第二电势的能量传递到另一钳口构件，以双极方式处理组织。
