Abstract
A surgical assembly for operably connecting an end effector to an electrosurgical instrument includes an adapter assembly and an extension assembly. The adapter assembly includes a drive coupling assembly, a drive transfer assembly operably received through the drive coupling assembly and including a first rotatable shaft, and a first pusher assembly operably connected to the first rotatable shaft for converting rotational motion from the first rotatable shaft to longitudinal movement to perform a first function. The first pusher assembly includes a first pusher member having an outer housing formed of a first material, and a threaded insert formed of a second material and disposed within the outer housing. The extension assembly is operably connected to a distal end of the adapter assembly, and includes a flexible band assembly operably connectable to the first pusher member of the first pusher assembly.
