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.
Claims27
An assembly for operably connecting an end effector to an electrosurgical instrument, the adapter assembly comprising:
- an adapter assembly including,
- a connector assembly;
- a drive transfer assembly operably received through the connector assembly and including first, second, and third rotatable shafts;
- 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;
- a second pusher assembly operably connected to the second rotatable shaft for converting rotational motion from the second rotatable shaft to longitudinal movement to perform a second function;
- and
- a drive member operably connected to the third rotatable shaft for transferring rotational motion from the third rotatable shaft to perform a third function;
- and
- an extension assembly operably connected to a distal end of the adapter assembly, the extension assembly including at least one flexible band assembly operably connected to one of the first and second pusher assemblies.
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.
A connection assembly for securing a first tubular member to a second tubular member, the connection assembly comprising:
- a tubular base including a flange and an annular rim;
- and
- a tubular extension including first and second sections and an outer sleeve slidably disposed about the first and second sections, wherein the first and second sections define an annular groove positioned to receive the annular rim of the tubular base when the first and second sections are received about the flange.
