Abstract
A surgical instrument includes an elongate shaft, a proximal clevis on the distal end of the shaft, a distal clevis coupled to the proximal clevis, and an end effector assembly. The distal clevis includes a proximally extending portion and a pair of bosses in fixed positions on the proximally extending portion. A first pin couples the end effector assembly to the distal clevis. A second pin, which has an axis perpendicular to the axis of the first pin, extends through the bosses to couple the proximal and distal clevises. Tendons extend from the end effector assembly around pulleys disposed on the bosses and through the shaft.
