Abstract
The present disclosure relates to adapter assemblies for use with and to electrically and mechanically interconnect electromechanical surgical devices and surgical loading units, and to surgical systems including handheld electromechanical surgical devices and adapter assemblies for connecting surgical loading units to the handheld electromechanical surgical devices.
Claims18
An adapter assembly for selectively interconnecting a surgical device and a surgical loading unit, the adapter assembly comprising:
- a housing;
- an outer tube extending distally from the housing along a longitudinal axis;
- a firing assembly supported within the housing and the outer tube, the firing assembly including:
- a proximal firing shaft;
- a central tube intersecting the proximal firing shaft at a proximal universal joint, the central tube movable relative to the proximal firing shaft about the proximal universal joint;
- and
- a distal firing shaft intersecting the central tube at a distal universal joint, the distal firing shaft movable relative to the central tube about the distal universal joint;
- and
- an articulation assembly including a gimbal supported in a distal end portion of the outer tube, the gimbal defining a gimbal bore therethrough configured and adapted to receive the distal universal joint such that the gimbal is disposed around the distal universal joint.
6 more elements
An electromechanical surgical system, comprising:
- a surgical device including a handle housing supporting a plurality of rotatable drive shafts;
- a surgical loading unit including at least one axially translatable drive member;
- and
- an adapter assembly selectively connectable between the surgical device and the surgical loading unit, the adapter assembly including:
- a housing;
- an outer tube extending distally from the housing along a longitudinal axis, a distal end portion of the outer tube releasably couplable to the axially translatable drive member of the surgical loading unit;
- and
- a firing assembly supported within the housing and the outer tube, the firing assembly including:
- a proximal firing shaft;
- a central tube intersecting the proximal firing shaft at a proximal universal joint, the central tube movable relative to the proximal firing shaft about the proximal universal joint;
- a distal firing shaft intersecting the central tube at a distal universal joint, the distal firing shaft movable relative to the central tube about the distal universal joint;
- and
- an input socket releasably couplable to at least one of the plurality of rotatable drive shafts of the surgical device.
