APPARATUS FOR ENDOSCOPIC PROCEDURES
First Claim
1. An electromechanical surgical system, comprising:
- a hand-held surgical instrument including an instrument housing defining a connecting portion for selectively connecting with a shaft assembly, the surgical instrument having at least one rotatable drive member;
an end effector configured to perform at least one function; and
the shaft assembly being arranged for selectively interconnecting the end effector and the surgical device, the shaft assembly including;
a transmission housing configured and adapted for selective connection to the connecting portion of the surgical device and to be in operative communication with each of the at least one rotatable drive member of the surgical device;
an outer tubular body having a proximal end supported by the transmission housing and a distal end configured and adapted for operative connection with the end effector;
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 a first end that is connectable to one rotatable drive member of the surgical instrument and a second end that is connectable to the rotation receiving member of the end effector, wherein the force transmitting assembly transmits a rotation of the rotatable drive member of the surgical instrument to the rotation receiving member of the end effector, the distal neck assembly including;
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, wherein the articulating neck assembly is configured to enable off-axis articulation of the distal neck assembly, and wherein the rotatable drive member extends through the articulating neck assembly.

Abstract
An electromechanical surgical system is provided including 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.
