Abstract
An electromechanical surgical device includes an end effector configured to perform at least one function, the end effector including an input drive axle projecting therefrom; and a shaft assembly. The shaft assembly includes a rotatable drive shaft; a proximal neck housing supported at a distal end of an outer tube; a distal neck housing pivotally connected to the proximal neck housing; a pivot pin interconnecting the proximal neck housing and the distal neck housing; and a gear train supported in the proximal neck housing, on the pivot pin, and in the distal neck housing. The gear train includes a proximal gear; an intermediate gear; a distal gear; and a pair of output gears, wherein each output gear defines a coupling socket each configured to selectively receive the drive axle of the end effector.
