A method of adjusting a uterine manipulator includes moving a colpotomizer cup of the uterine manipulator along a curved shaft of the uterine manipulator in a manner such that a distal face of the colpotomizer cup remains centered on an arch centerline of the curved shaft and an axial centerline of the colpotomizer cup remains offset from the arch centerline of the curved shaft at an opening of the colpotomizer cup that is spaced proximally from the distal face of the colpotomizer cup.
