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.
Claims18
An adapter assembly for operably connecting an end effector to a surgical instrument, comprising:
- a base;
- a support structure rotatable relative to the base along a longitudinal axis, wherein the support structure includes a plurality of plates and a plurality of tubular supports maintaining the plates in spaced apart relation;
- a rotation handle rotatably secured to the base and fixedly secured to a proximal end of the support structure, wherein rotation of the rotation handle causes rotation of a distal portion of the adapter assembly relative to a proximal end of the adapter assembly;
- a latch, mounted to an outer surface of the rotation handle, the latch including a pin biased into engagement with a notch formed in the base to selectively lock the rotation handle in a fixed longitudinal position;
- a drive coupling assembly disposed within the base and configured for operable connection to the surgical instrument;
- a drive transfer assembly disposed within the base and operably connected to the drive coupling assembly;
- and
- first and second pusher assemblies disposed within the support structure and operably connected to the drive transfer assembly.
An adapter assembly for operably connecting an end effector to a surgical instrument, comprising:
- a base;
- a support structure rotatable relative to the base along a longitudinal axis, the support structure including:
- a plurality of plates;
- a plurality of tubular supports maintaining the plates in spaced apart relation;
- at least one support ring positioned between adjacent plates;
- a plurality of ribs positioned between adjacent plates;
- and
- a plurality of rivets securing the plates, tubular supports, support rings, and ribs together;
- a drive coupling assembly disposed within the base;
- and
- first and second pusher assemblies disposed within the support structure.
An adapter assembly for operably connecting an end effector to a surgical instrument, comprising:
- a proximal portion;
- a distal portion rotatable relative to the proximal portion along a longitudinal axis;
- an outer sleeve;
- a support structure secured within the outer sleeve and rotatable with the distal portion relative to the proximal portion, the support structure including a plurality of proximal tabs and a distal tabs extending radially and at least partially through the outer sleeve;
- and
- first and second pusher assemblies disposed within the support structure and configured to convert rotational input from a drive transfer assembly into longitudinal movement, wherein the first and second pusher assemblies are rotatable relative to the surgical instrument.
