Uterine manipulator with externally securable clamp

Claim 1

A uterine manipulator device comprising: an elongate tube having an insertable end adapted to be inserted through the cervical canal into the uterine cavity and an opposite end which locates outside the external opening of the vagina with the manipulator device in place, said tube having means defining a passage extending therealong and the passage having an inlet port adjacent its said opposite end and terminating in a discharge port adjacent said insertable end, said passage serving to channel fluid introduced thereinto along the tube with such delivered to sid discharge port, an inflatable member mounted on said discharge end of the tube with the interior thereof communicating with said discharge port and adapted to be inflated with said fluid channeled by said passage, an elongate plastic sheath having an internal passage extending therealong, said tube being lodged loosely within said passage with the sheath in nonclamping relation relative thereto and thus freely slidable relative to the tube, a stop integrally formed with one end of the sheath, also in loose slidable relation with respect to the tube, located adjacent but inwardly from the tube's insertable end, and a manually operable clamp joined to the opposite end of the sheath at a location which is exteriorly of the external opening of the vagina with the device in place and located adjacent but inwardly from the tube's opposite end having a clamping position wherein the clamp clamps onto the tube and a release position wherein the clamp releases the tube said sheath constituting a compression and tension transmitting connector extending between the clamp and stop and producing with release of the clamp and shifting of the clamp along the tube, corresponding movement in the stop enabling the stop to be properly positioned relative to the entrance of the cervical canal.
