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 hand held electromechanical surgical devices and adapter assemblies for connecting surgical loading units to the hand held electromechanical surgical devices.
Claims18
An adapter assembly for selectively interconnecting a surgical loading unit that is configured to perform a function and a surgical device that is configured to actuate the surgical loading unit, the adapter assembly comprising:
- a housing;
- an outer tube supported by the housing and defining a longitudinal axis;
- a gimbal supported in the outer tube;
- and
- a plurality of threaded sleeves supported in the housing and coupled to the gimbal by at least one cable, the plurality of threaded sleeves supported on at least one threaded screw, at least one threaded sleeve of the plurality of threaded sleeves positioned to move the at least one cable relative to the outer tube to omni-directionally articulate the gimbal and the surgical loading unit relative to the longitudinal axis of the outer tube.
An electromechanical surgical system, comprising:
- a surgical loading unit;
- an electromechanical surgical device;
- and
- an adapter assembly selectively connectable between the electromechanical surgical device and the surgical loading unit, the adapter assembly including:
- a gimbal and a plurality of threaded sleeves, the plurality of threaded sleeves coupled to the gimbal by at least one cable, the plurality of threaded sleeves supported on at least one threaded screw, the plurality of threaded sleeves being movable to articulate the gimbal with the at least one cable, wherein articulation of the gimbal articulates the surgical loading unit;
- and
- a firing shaft movable with the gimbal to omni-directionally articulate the surgical loading unit and rotatable to fire the surgical loading unit.
