Abstract
An assembly including an adapter assembly and an extension assembly for connecting an end effector to an electrosurgical instrument is provided. The adapter assembly includes first and second pusher assemblies configured for converting rotational motion into linear motion and a drive member for transferring rotational motion. The extension assembly includes at least one flexible band assembly for transferring the linear motion from the adapter assembly and a trocar assembly configured for converting rotational motion into linear motion. Also provided is a connection assembly for connecting a first tubular member to a second tubular member.

1-15. (canceled)
An extension assembly for operably connecting an end effector to an electrosurgical instrument, the extension assembly comprising:
- an outer sleeve;
- a frame assembly received within the outer sleeve;
- an inner flexible band assembly slidably disposed within the frame assembly for performing a first function;
- an outer flexible band assembly slidably disposed within the frame assembly and relative to the inner flexible band assembly for performing a second function;
- and
- a trocar assembly disposed within the frame assembly and including a trocar member for performing a third function.
25-27. (canceled)
An extension assembly for operably connecting an end effector to a surgical instrument, the extension assembly comprising:
- an outer sleeve having proximal and distal portions;
- a frame assembly received within the outer sleeve;
- an inner flexible band assembly slidably disposed within the frame assembly, for performing a first function;
- and
- an outer flexible band assembly slidably disposed within the frame assembly and relative to the inner flexible band assembly, for performing a second function.
