摘要：
An electromechanical surgical system includes a hand-held surgical instrument； an end effector； and a shaft assembly for selectively interconnecting the end effector and the surgical device. The shaft assembly includes a transmission housing； an outer tubular body； a distal neck housing for interconnecting a rotatable drive member of the surgical instrument and a rotation receiving member supported in the end effector, wherein the distal neck housing includes at least one gear system configured to convert a rotational input of the rotatable drive member into at least two output forces to the end effector； and an articulating neck assembly interconnecting the tubular body and the distal neck housing. The articulating neck assembly enables off-axis articulation of the distal neck assembly, and wherein the rotatable drive member extends through the articulating neck assembly.
