Abstract
An electrosurgical instrument includes a housing having a handle and an elongate shaft extending from the handle to support an end effector assembly. The end effector assembly includes first and second jaw members each having a jaw housing and an electrically conductive tissue engaging surface. The first jaw member includes a U-shaped proximal flange defining a cuff having sides configured to support a pivot, and further defining a cradle for securing a pivot rod. The second jaw member defines a U-shaped cuff for receiving the proximal flange of the first jaw member. The cuff includes sides defining a cradle for supporting the pivot thereon via a range of motion between the first and second jaw members.
