Uterine manipulator with detachable cup and locking occluder
A uterine manipulator includes a handle and a central shaft that extends distally from the handle. The central shaft includes a distal end portion supporting a balloon. The central shaft also supports a cervical cup. An occluder shaft is slidably supported on the central shaft. A non-inflatable plug is secured to the occluder shaft and configured to move with the occluder shaft as the occluder shaft slides along the central shaft.
1. A uterine manipulator, comprising:
a central shaft supporting a balloon and a cervical cup;
an occluder shaft movably engaged with the central shaft;
a non-inflatable plug positioned to move with the occluder shaft as the occluder shaft moves along the central shaft; and
a shuttle selectively engaged with the cervical cup and removably received within the non-inflatable plug.
2. The uterine manipulator of claim 1 , wherein the cervical cup is selectively detachable from the central shaft.
3. The uterine manipulator of claim 2 , wherein the cervical cup includes at least one light emitting diode.
4. The uterine manipulator of claim 1 , wherein the occluder shaft slides along an outer surface of the central shaft.
5. The uterine manipulator of claim 1 , wherein the shuttle includes at least one tab that is depressible to selectively couple the shuttle to the cervical cup.
6. The uterine manipulator of claim 5 , wherein the cervical cup includes a ledge, the at least one tab positioned to engage the ledge of the cervical cup to selectively secure the shuttle and the cervical cup together.
7. The uterine manipulator of claim 6 , wherein the cervical cup includes a raised ring that extends from the ledge and is positioned to surround the at least one tab.
8. The uterine manipulator of claim 1 , wherein the central shaft includes a collar adjacent to the balloon, the collar positioned to engage the shuttle to prevent the cervical cup from sliding off the central shaft while the cervical cup is coupled to the shuttle.
9. The uterine manipulator of claim 1 , further comprising a locking mechanism having a spring supported about the central shaft and positioned to selectively lock the occluder shaft to the central shaft to prevent the occluder shaft from sliding along the central shaft.
10. The uterine manipulator of claim 1 , wherein the non-inflatable plug has a tapered configuration that is configured to be received within a vagina to occlude the vagina.
11. A manipulator, comprising:
a central shaft;
a cervical cup;
a shuttle selectively secured to the cervical cup and supported for movement with the cervical cup along the central shaft;
an occluder shaft; and
a plug coupled to the occluder shaft and removably supporting the shuttle therein.
12. The manipulator of claim 11 , wherein the plug is positioned to slide along the central shaft independent of the shuttle.
13. The manipulator of claim 11 , wherein the occluder shaft slides along an outer surface of the central shaft.
14. The manipulator of claim 11 , wherein the plug includes a foam material.
15. The manipulator of claim 11 , wherein the plug has a tapered configuration that is configured to be received within a vagina to occlude the vagina.
16. The manipulator of claim 11 , wherein the plug has a frustoconical configuration.
17. The manipulator of claim 11 , wherein the cervical cup includes at least one light emitting diode.
18. A uterine manipulator, comprising:
a central shaft;
a cervical cup;
a shuttle selectively secured to the cervical cup and supported for movement with the cervical cup along the central shaft;
an occluder shaft supporting a locking mechanism that is configured to prevent relative movement between the occluder shaft and the central shaft; and
a plug coupled to the occluder shaft and removably supporting the shuttle therein.
19. The uterine manipulator of claim 18 , wherein the locking mechanism supports a torsion spring that prevents the occluder shaft from sliding along the central shaft when the torsion spring is disposed in a first position.
20. The uterine manipulator of claim 19 , wherein the locking mechanism includes an actuator coupled to the torsion spring, the actuator positioned for actuation to tension the torsion spring toward a second position, wherein the occluder shaft is positioned to slide along the central shaft when the torsion spring is disposed in the second position.
