    • Various mechanisms, and a method of operating them, are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by means of the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation. In the first angular orientation, the fastener advancing member is restrained against longitudinal movement to assist in installation of the cartridge onto the instrument. The distal end of the instrument can be articulated, and a helical gear operator is provided for effecting the articulation. The helical gear pitch decreases in a direction such that the mechanical advantage is increased as the articulation angle increases. A trigger actuating system includes a trigger lever with a cam channel, a pin in the cam channel, and a link connected at one end to the pin and at the other end to a reciprocatable driver. A frame is provided with a guide channel for guiding an end of the pin. The trigger lever is pivotally mounted to the frame and biased to a normally unactuated position.
    • 各种机构及其操作方法被提供用于外科器械。 提供轴和啮合的空转操作旋钮以相对于手柄部分旋转。 闩锁系统防止轴旋转,除非轴通过旋钮旋转。 设置有用于在轴的远端旋转的盒。 提供接合结构,用于当轴向力施加到盒时防止盒相对于轴旋转。 提供装载工具用于接合盒以将盒安装在仪器上。 盒包括用于接合载体的垫圈,在该托架上安装盒,以防止垫圈旋转。 垫圈适于以第一角度定向接合紧固件前进构件,并且当盒被旋转以建立第二相对角度取向时,该垫圈脱离。 在第一角度定位中,紧固件前进构件被限制在纵向运动中,以帮助将盒安装到仪器上。 仪器的远端可以铰接,并且提供斜齿轮操作器来实现铰接。 螺旋齿轮间距沿着使得机械优点随着铰接角度增加而增加的方向减小。 触发器致动系统包括具有凸轮通道的触发杆,凸轮通道中的销,以及在一端连接到销并且另一端连接到可往复运动的驱动器的连杆。 框架设置有用于引导销的端部的引导通道。 触发杆枢转地安装到框架并且被偏压到正常未动作的位置。
