Adapter assembly with gimbal for interconnecting electromechanical surgical devices and surgical loading units, and surgical systems thereof
First Claim
1. 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 surgical loading unit including an axially translatable drive member, and the surgical device including a plurality of rotatable drive shafts, the adapter assembly comprising:
- a housing configured and adapted for connection with the surgical device and to be in operative communication with each rotatable drive shaft of the plurality of rotatable drive shafts of the surgical device;
an outer tube having a proximal end supported by the housing and a distal end configured and adapted for connection with the surgical loading unit, wherein the distal end of the outer tube is in operative communication with the axially translatable drive member of the surgical loading unit, the outer tube defining a longitudinal axis; and
an articulation assembly including a gimbal supported in the outer tube and a plurality of threaded sleeves supported in the housing, the plurality of threaded sleeves coupled to the gimbal by at least one cable,wherein rotation of at least one of the plurality of rotatable drive shafts of the surgical device translates at least two of the plurality of threaded sleeves to omni-directionally articulate the gimbal relative to the longitudinal axis of the outer tube with the at least one cable, and wherein articulation of the gimbal articulates the surgical loading unit about the distal end of the outer tube.

12. An electromechanical surgical system, comprising:
-
a surgical loading unit including at least one axially translatable drive member; a handle-held electromechanical surgical device including; a housing; and at least one rotatable drive shaft supported in the housing; and an adapter assembly selectively connectable between the housing of the surgical device and the surgical loading unit, the adapter assembly including; an articulation 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 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 connectable between the at least one rotatable drive shaft of the surgical device and the at least one axially translatable drive member, the firing shaft being movable with the gimbal to omni-directionally articulate the surgical loading unit and rotatable to translate the at least one axially translatable drive member through the surgical loading unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
