Abstract
An adapter assembly for connecting an end effector to an electrosurgical instrument is provided. The adapter assembly includes a drive transfer assembly, first and second pusher assemblies, a drive member, an extension assembly, and a trocar assembly. The drive transfer assembly includes first, second and third rotatable shafts. Each pusher assembly is operably connected to a rotatable shaft for converting rotational motion from one rotatable shaft to longitudinal movement to perform a different function. The drive member is operably connected to the third rotatable shaft for transferring rotational motion from the third rotatable shaft to perform a third function. The extension assembly is operably connected to a distal end of the adapter assembly and includes at least one flexible band assembly operably connected to one of the first and second pusher assemblies. The trocar assembly is configured for releasable engagement with the extension assembly.
