摘要：
A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly, an end effector, and a rotational knob operable to rotate the transmission assembly and the end effector. The body assembly includes a trigger and a casing having a distal aperture configured to receive a portion of the end effector assembly. First and second coupling mechanism portions cooperatively couple the end effector assembly to the body assembly for use. The coupling may mechanically and/or electrically couple the end effector assembly to the body assembly via various coupling mechanisms. For instance, a threaded slip nut may couple to threads within the body assembly. In one configuration, the end effector assembly may have locking tabs that rotate into rotational recesses in the body assembly. The locking tabs may include electrical contacts and/or optically perceivable indicators.
