An end effector comprising: a first jaw member including: a first camming member configured to be engaged by a clamping sleeve for moving said end effector between an open and a clamped position and defining a first rotation hole and a first pivot hole; a first body having a first proximal tab defining a first rotation opening and a first articulation opening; and a first coupling member having a first rotation post and a first articulation post, the first rotation post inserted in the first rotation hole and the first rotation opening, the first articulation post positioned within the first articulation opening; a second jaw member including: a second camming member configured to be engaged by a clamping sleeve for moving said end effector between an open and a clamped position and defining a second rotation hole and a second pivot hole; a second body having a second proximal tab defining a second rotation opening and a second articulation opening; and a second coupling member having a second rotation post and a second articulation post, the second rotation post inserted in the second rotation hole and the second rotation opening, the second articulation post positioned within the second articulation opening; and a pivot pin positioned in the first and second pivot holes, said first and second camming members being adapted to pivot about said pivot pin allowing the pivoting of the first and second jaw members relative to one another between an open configuration and a clamped configuration about the pivot pin in a parallel manner, the first and second bodies articulatable relative to the first and second camming members about the first and second articulation posts the first and second camming members configured for operative association with a clamping mechanism to pivot the first and second jaw members relative to one another about the pivot pin between the open configuration and the clamped configuration. a first jaw member including: a first camming member configured to be engaged by a clamping sleeve for moving said end effector between an open and a clamped position and defining a first rotation hole and a first pivot hole;
