Uterine manipulators and related components and methods
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.
1. A method of adjusting a uterine manipulator, comprising 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 and through which the curved shaft passes.
2. The method of claim 1 , wherein the colpotomizer cup comprises a body that defines the distal face.
3. The method of claim 2 , wherein the body defines a recess configured to receive a cervix.
4. The method of claim 3 , wherein the body defines a plurality of viewing windows for visualizing the cervix within the body.
5. The method of claim 2 , wherein the body defines a beveled rim configured to provide an anatomical landmark and an incision backstop.
6. The method of claim 1 , wherein the colpotomizer cup comprises a base defining the opening.
7. The method of claim 1 , wherein, at the opening of the colpotomizer cup, the axial centerline of the colpotomizer cup remains offset from the arcuate centerline of the curved shaft by about 0.065 inch to about 0.085 inch.
8. The method of claim 1 , wherein moving the colpotomizer cup comprises moving a sleeve that is connected to the colpotomizer cup.
9. The method of claim 8 , wherein the sleeve defines a channel configured to receive the curved shaft.
10. The method of claim 8 , further comprising locking the colpotomizer sleeve at a predetermined location along the curved shaft.
11. The method of claim 1 , wherein the arch centerline of the curved shaft remains aligned with a centerpoint of distal face of the colpotomizer cup as the colpotomizer cup is moved along the curved shaft.
12. The method of claim 1 , further comprising preventing the colpotomizer cup from tilting with respect to the arch centerline of the curved shaft as the colpotomizer cup is moved along the curved shaft.
13. The method of claim 1 , wherein the opening of the colpotomizer cup is radially spaced from the axial centerline of the colpotomizer cup.
