1. A surgical instrument comprising:

  • a handle;

    a shaft assembly extending distally from the handle, wherein the shaft assembly defines a central axis, and wherein the shaft assembly defines an outer circumference; and

    an end effector coupled to a distal end of the shaft assembly, wherein the end effector comprises;

    a jaw assembly, comprising;

    a proximal end;

    a distal end; and

    a curved body extending from the proximal end to the distal end of the jaw assembly, the curved body comprising;

    a moveable jaw member extending from the proximal end to the distal end of the jaw assembly; and

    a fixed jaw member extending from the proximal end to the distal end of the jaw assembly, wherein the moveable jaw member is pivotably moveable between an open position and a closed position with respect to the fixed jaw member;

    wherein, in the closed position, the curved body defines a radius of curvature and a smooth taper along the curved body from the proximal end to the distal end of the jaw assembly, wherein the curved body is contained within a cylindrical volume defined by the outer circumference of the shaft assembly and extending distally from the shaft assembly along the central axis, and wherein the central axis of the shaft assembly comprises a first side and a second side; and

    a cutting member longitudinally deployable within a longitudinal curved slot defined by the jaw assembly, wherein the longitudinal curved slot comprises a proximal portion substantially in-line with the central axis of the shaft assembly, and wherein the longitudinal curved slot substantially follows the radius of curvature of the curved body.
