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;
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 distal neck housing transmits a rotation of the rotatable drive member of the surgical instrument to the rotation receiving member of the end effector, the distal neck housing 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, wherein a first output force of the at least one gear system of the distal neck housing results in a firing of the end effector or a rotation of the end effector relative to the shaft assembly;
a lock collar non-rotatably and slidably supported on the distal neck housing, the lock collar movable between a first position wherein the first output force of the at least one gear system of the distal neck housing results in the firing of the end effector, and a second position wherein the first output force of the at least one gear system of the distal neck housing results in the rotation of the end effector relative to the shaft assembly; 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
The present disclosure relates to electromechanical surgical systems configured for use with removable disposable loading units and/or single use loading units for clamping, cutting and/or stapling tissue. A force transmitting assembly of surgical instrument transmits a rotation of a rotatable drive member of the surgical instrument to the rotation receiving member of the end effector. A distal neck assembly of the surgical instrument 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 is configured to enable off-axis articulation of the distal neck assembly. The rotatable drive member extends through the articulating neck assembly.
