1. A surgical instrument comprising:

  • a shaft having a proximal end and a distal end, a longitudinal axis being defined between the proximal and distal ends;

    a wrist having a proximal end and a distal end, the proximal end of the wrist being coupled to the distal end of the shaft, the wrist being movable in pitch and yaw degrees of freedom, wherein the pitch degree of freedom is defined orthogonal to the longitudinal axis, and wherein the yaw degree of freedom is defined orthogonal to the longitudinal axis and to the pitch degree of freedom;

    a surgical end effector coupled to the wrist, the surgical end effector comprising a jaw mechanism and a translating component, the translating component being movable lengthwise relative to the jaw mechanism;

    a jaw mechanism drive element extending through the wrist and coupled to the jaw mechanism; and

    a translating component drive element extending through the wrist and coupled to the translating component of the surgical end effector, the translating component being configured to move lengthwise relative to the jaw mechanism in response to the translating component drive element translating along the longitudinal axis.
