Uterine manipulator
A uterine manipulator device includes: an elongated cannulated tube having proximal and distal ends, a cervical cup positioned on the elongated cannulated tube with a top distal portion of a first diameter and a base proximal portion of a second smaller diameter, and an occluder assembly comprising an occluder positioned proximally from the cervical cup on the elongated cannulated tube, the occluder having a body with at least one primary rib and at least two secondary ribs, wherein a diameter of at least one secondary rib is smaller than the diameter of the primary rib.
1 . A uterine manipulator device, comprising:
an elongated cannulated tube comprising a proximal end and a distal end;
a cervical cup positioned on the elongated cannulated tube having a top distal portion of a first diameter and a base proximal portion of a second smaller diameter;
an intrauterine balloon comprising a proximal end and a distal end and being positioned on the distal end of the elongated cannulated tube, wherein the proximal end and the distal end of the intrauterine balloon are secured to the elongated cannulated tube with heat shrink material;
a spheroid shaped occluder having a first side and a second side and positioned on a stem positioned proximally from the cervical cup on the elongated cannulated tube, wherein the spheroid shaped occluder includes an opening allowing passage therethrough of the elongated cannulated tube; and
a first barrier rib positioned on the elongated cannulated tube and adjacent to the first side of the spheroid shaped occluder, and a second barrier rib positioned on the elongated cannulated tube and adjacent to the second side of the spheroid shaped occluder.
2 . The device of claim 1 , further comprising a handle positioned on the proximal end of the elongated cannulated tube.
3 . The device of claim 2 , further comprising an inflation valve positioned through the handle and communicatively coupled to a gas passage lumen in the elongated cannulated tube.
4 . The device of claim 2 , further comprising an enclosed cavity positioned between the elongated cannulated tube and the intrauterine balloon, and which communicatively connects to the gas passage lumen.
5 . The device of claim 2 , further comprising a dye injection port positioned through the handle and communicatively coupled to the elongated cannulated tube and a cap positioned on the distal end of the elongated cannulated tube.
6 . The device of claim 5 , wherein the elongated cannulated tube further comprises a mechanical retaining feature configured to secure the cap to the elongated cannulated tube.
7 . The device of claim 5 , wherein the cap comprises a proximal end and a distal end, and at least one channel passing therethrough.
8 . The device of claim 7 , wherein the at least one channel extends through a side of the cap from the proximal end to the distal end of the cap.
9 . The device of claim 7 , wherein the at least one channel is centrally positioned within the cap and extends between the distal end and the proximal end of the cap.
10 . The device of claim 9 , wherein the at least one channel bifurcates into at least one additional channel.
11 . The device of claim 2 , further comprising a square key feature in the handle which directs an applied force in one direction only.
12 . The device of claim 1 , wherein the intrauterine balloon is composed of a thermoplastic elastomer.
13 . A method of manufacturing the uterine manipulator device of claim 1 , comprising the steps of:
applying a layer of heat shrink to the outside surface of the elongated cannulated tube, and
applying laser mark reference graduations along an outside surface of the heat shrink on the elongated cannulated tube.
14 . The method of claim 13 , wherein the laser mark reference graduations are applied using a UV laser emitting a wavelength of 355 nm.
15 . The method of claim 13 , wherein the heat shrink layer comprises an acrylated polyolefin layer.
