    • An endoscopic bipolar forceps includes a housing having a shaft affixed thereto, the shaft including jaw members at a distal end thereof. The shaft incudes a longitudinal axis defined therethrough and the jaw members are adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. The forceps also includes a drive assembly which moves the jaw member 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 movable handle is included which is rotatable about a pivot to force the drive assembly to move the jaw members between the first and second positions. The pivot is located a fixed distance above the longitudinal axis. A knife assembly is also included which has a movable knife bar having a generally i-shaped proximal end dimensioned to operatively engage a corresponding slot defined within the housing, the slot being dimensioned to guide the movement of the knife bar during translation thereof.
    • 内窥镜双极镊子包括具有固定在其上的轴的壳体,所述轴在其远端包括钳口构件。 所述轴包括通过其限定的纵向轴线,并且所述钳口构件适于连接至电外科能量源,使得所述钳口构件能够通过保持在其间的组织传导能量以实现组织密封。 所述钳子还包括驱动组件,所述驱动组件使所述钳夹构件相对于彼此从其中所述钳夹构件相对于彼此以间隔关系布置的第一位置移动到第二位置,在所述第二位置,所述钳夹构件彼此更接近以操纵组织。 包括可移动手柄,其可围绕枢轴旋转以迫使驱动组件在第一位置和第二位置之间移动钳口构件。 枢轴位于纵轴上方的固定距离处。 还包括刀组件,该刀组件具有可移动的刀杆,所述刀杆具有大致为i形的近端,所述近端的尺寸被设计成可操作地接合限定在壳体内的对应的槽,所述槽的尺寸被设定为引导刀杆在其移动期间的移动。

    • 内窥镜双极镊子包括具有固定到其上的轴的壳体,该轴在其远端包括钳口构件。 轴包括穿过其中限定的纵向轴线,并且钳口构件适于连接到电外科能量源,使得钳口构件能够通过夹持在其间的组织传导能量以实现组织密封。 镊子还包括驱动组件,该驱动组件使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间隔开地设置到第二位置,其中钳口构件彼此更靠近以操纵组织。 包括可移动手柄,其可围绕枢轴旋转,以迫使驱动组件在第一和第二位置之间移动钳口构件。 枢轴位于纵向轴线上方固定的距离处。 还包括刀组件,其具有可移动的刀杆,其具有大致t形的近端尺寸,以可操作地接合限定在壳体内的相应狭槽,该狭槽的尺寸被设计成引导刀片在其平移期间的运动。
