Provided are uterine manipulators comprising in combination: a vaginal occlusion portion comprising a resilient deformable member (e.g., bulb, cone, cylinder, etc.) having a channel therethrough having a proximal opening sized to fit, during use of the device, snuggly against a manipulation rod or tube, and a relatively larger distal opening suitable to provide for angular and/or rotational movement of the rod or tube passing through the member via the distal and proximal openings while minimizing movement of the vaginal occlusion member when the tube is subjected to manipulation, and wherein the member is suitably configured to fit snugly against the contours of an inner vaginal tissue surface; and a cervical fitting portion which is securable to the cervix. Also provided are surgical methods using said elements to provide for a snug fit with the cervix while sealing the vagina, wherein maintaining abdominal insufflation during surgery is afforded.

A vaginal cervical retractor used to maneuver and visualize the uterus during various medical examinations and procedures would include an inner tube provided with a movable assembly of plastic cups (cervical cup and vaginal cup) designed to be inserted into the uterine cavity and a retractable electrosurgical needle. A cervical cup is molded to a hollow outer shaft to form the movable cup assembly. This hollow shaft is provided through which the inner tube can be inserted. By utilizing a vaginal cervical retractor elevator provided with an inner rigid tubing, freely sliding vaginal cup and cervical cup designed to move on the inner tubing, attached to a hollow, plastic outer shaft into which the inner tubing can be inserted, and a retractable, flexible, electrosurgical needle, the colpotomy procedure can be performed with the improved uterine manipulator.

A cup-like structure for engaging a cervix of a patient includes a rim, and includes a base defining an aperture through which one or more tubular members of a uterine manipulator may extend into the uterus. The cup-like structure is made from one or more of a polyphthalamide (PPA) material and a polyetheretherketone (PEEK) material. A uterine manipulator including a cup-like structure is also disclosed.

A uterine manipulator operable to detach the uterus and cervix from the vagina. The uterine manipulator includes an umbrella-like tip that creates a secure connection between the uterine manipulator and the uterus and cervix. The uterine manipulator also includes a pneumooccluder that enables rotation of the manipulator shaft while maintaining pneumoperitoneum. The uterine manipulator further includes a cutter that travels in a circle at the junction of the cervix and the vagina, permitting detachment of the uterus and cervix from the top of the vagina.

A uterine manipulator includes a sound and a body. The sound has a selectively actuatable anchor disposed proximate a distal end and an operating mechanism spaced from the anchor for controlling actuation of the anchor. The body has a passage therethrough adapted to receive the sound passed proximally through the body to a position in which the operating mechanism is accessible proximally of the body and the anchor extends distally.

A uterine manipulator is described that includes an elongated, hollow shaft having a proximal end and a distal end. The hollow shaft defines a channel and has a non-opaque distal tip. A handle is positioned on a proximal portion of the shaft and an inflatable balloon is supported on a distal portion of the shaft. The inflatable balloon is transitional from a deflated state to an inflated state. A cervical cup is movably positioned along the shaft from a distal position to a proximal position. The channel of the shaft is dimensioned to receive an endoscope to facilitate visualization of a body lumen through the non-opaque distal tip of the shaft. In embodiments, the cervical cup defines a rim that is positioned to abut the inflatable balloon when the cervical cup is in its distal position. The rim includes a plurality of distally facing lights that function to identify placement of the cervical cup in relation to the cervix.

The invention relates to a medical instrument, in particular to a cup-adjustable uterine manipulator. The cup-adjustable uterine manipulator comprises a uterine manipulator cup, a guide rod and a hollow operating rod connected with the uterine manipulator cup, wherein the uterine manipulator cup consists of at least two blades distributed along the same circumference; the middle of each blade in the axial direction is hinged to a support frame; the lower end of each blade is hinged to a hollow adjusting rod; the hollow adjusting rod moves up and down to drive each blade to rotate around the support frame and is arranged in the inner chamber of the operating rod; and the guide rod penetrates the inner chamber of the adjusting rod to be connected with the support frame and can move up and down along the inner chamber of the adjusting rod. According to the cup-adjustable uterine manipulator, the adjusting rod moves up and down to drive the lower ends of the blades to move and to enable the blades to rotate around the fixed axis, so that the blades are stretched or gathered to realize adjustment of the cup size, and the purpose that the uterine manipulator is suitable for different cervical diameters is achieved.

Exemplary embodiments of the present invention comprise a laparoscopic uterine manipulator device assembly. The laparoscopic uterine manipulator assembly comprises a laparoscopic control device configured for insertion into the abdomen-pelvic cavity of a patient. The laparoscopic uterine manipulator assembly further comprises a uterine manipulator device, the uterine manipulator device configured for insertion and advancement through a vaginal and uterine cavity. A primary member of a device coupling mechanism of the uterine manipulator device is mechanically engaged with a secondary member of the device coupling mechanism of the laparoscopic control device, resulting in the construction of an assembly comprising the laparoscopic control device and the uterine manipulator device. Assembled, the laparoscopic uterine manipulator assembly allows an individual user to utilize the device to engage and reposition the patient's uterus in a manner that allows for the performance of a gynecological laparoscopic medical procedure for the maximum benefit of the patient.
