Apparatus for endoscopic procedures
First Claim
1. A shaft assembly for interconnecting at least one rotatable drive shaft of a hand-held electromechanical surgical device and an end effector, the shaft assembly comprising:
- a shaft coupling assembly including a drive member configured to connect to a rotatable drive shaft of a surgical device;
an outer tube having a proximal end portion supported by the shaft coupling assembly, the outer tube defining a central longitudinal axis;
a neck portion including;
a proximal neck portion supported at a distal end portion of the outer tube;
a distal neck portion pivotally connected to the proximal neck portion, the distal neck portion configured to connect to an end effector;
a hub rotatably supported at the distal neck portion, the hub rotatable about an axis of rotation coaxial with the central longitudinal axis; and
a rotation nut rotatably supported in the hub and connected to a distal end portion of the drive member, the rotation nut radially offset from the central longitudinal axis and configured to selectively connect to a rotatable drive axle of an end effector.

Abstract
A shaft assembly is provided for interconnecting at least one rotatable drive shaft of a hand-held electromechanical surgical device, and an end effector actuatable by an axial drive force. The shaft assembly includes a flexible drive cable rotatably supported in an outer tube, the flexible drive cable includes a proximal end operatively connected to a respective rotatable drive shaft of the hand-held surgical device. The flexible drive cable being off set a radial distance from a central longitudinal axis of the outer tube. The shaft assembly includes an articulation rod at least partially slidably supported in the outer tube, and an articulation link having a proximal end pivotally connected to the distal end of the articulation rod and a distal end pivotally connected to a distal neck housing. The articulation rod being off set a radial distance from the central longitudinal axis of the outer tube.
