包括可替换端部执行器的外科器械系统
摘要：
本发明公开了一种外科器械系统，所述外科器械系统包括外壳和可旋转驱动轴、可操作地联接到所述驱动轴的马达、和能够连接到所述外壳的多个可替换端部执行器。每个可替换端部执行器包括驱动螺杆，当所述端部执行器连接到所述外壳时，所述驱动螺杆由所述马达驱动的可旋转驱动轴转动固定数量的转数。每个端部执行器还包括与所述端部执行器的驱动螺杆可操作地联接的击发构件。所述驱动螺杆能够因所述固定数量的转数而使所述击发构件移动击发长度。在某些实施例中，每个可替换端部执行器能够包括具有螺距的驱动螺杆，所述螺距被设定为所述击发长度除以所述固定数量的转数。
摘要（英）：

A surgical instrument system that includes a housing and a rotatable drive shaft, a motor operably coupled to the drive shaft, and a plurality of replaceable end effectors that can be connected to the housing. Each replaceable end effector includes a drive screw that is turned a fixed number of revolutions by the motor-driven rotatable drive shaft when the end effector is connected to the housing. Each end effector further comprises a firing member operably coupled with the drive screw of the end effector. The drive screw is configured to displace the firing member over a firing length as a result of the fixed number of revolutions. In certain embodiments, each replaceable end effector can include a drive screw with a thread pitch set to the firing length divided by the fixed number of revolutions.
