Uterine manipulator
A uterine manipulator device includes: an elongated cannulated tube comprising a proximal end and a distal end; a cervical cup having a top proximal portion of a first diameter and a base distal portion of a second smaller diameter, wherein: the base distal portion includes a hole formed therein having a perimeter including a distal end and a proximal end, and including a longitudinal axis positioned therethrough; one of the proximal end of the perimeter and the distal end of the perimeter is angled away from the longitudinal axis and the other of the proximal end of the perimeter and the distal end of the perimeter is in line with the longitudinal axis; and the elongated cannulated tube is positioned through the hole in the cervical cup.
1. A uterine manipulator device comprising:
an elongated cannulated manipulator tube comprising a first end and a second end, wherein the first end includes a handle positioned thereon;
a cervical cup having a top portion of a first diameter and a base portion of a second smaller diameter, the base portion being positioned closer to the handle as compared with the top portion, wherein:
the base portion includes a hole formed therein having a perimeter including a first end and a second end, the first end of the perimeter being positioned closer to the handle as compared with the second end of the perimeter, and including a longitudinal axis positioned therethrough;
the second end of the perimeter is angled away from the longitudinal axis and the first end of the perimeter is parallel to the longitudinal axis;
and
the elongated cannulated manipulator tube is positioned through the hole in the cervical cup,
a retention mechanism comprising a retention ring positioned on the elongated cannulated manipulator tube adjacent to the cervical cup and a ring of heat shrink positioned on the elongated cannulated manipulator tube adjacent to the retention ring, wherein the ring of heat shrink extends longer in an axial direction than the retention ring, and wherein the retention ring is configured to prevent detachment of the cervical cup from the manipulator tube.
2. The device of claim 1 , wherein the first end of the elongated cannulated manipulator tube is nonlinear.
3. The device of claim 1 , further comprising a vaginal cup positioned closer to the handle than the cervical cup on the elongated cannulated manipulator tube, wherein the vaginal cup includes a top portion with a first diameter and a base portion with a second smaller diameter, and wherein the vaginal cup is configured to maintain pneumoperitoneum during use.
4. The device of claim 3 , further comprising a locking assembly positioned closer to the handle than the vaginal cup configured to lock the cervical cup and vaginal cup in place during use.
5. The device of claim 1 , further comprising an intrauterine balloon positioned on the second end of the elongated cannulated manipulator tube and having a first end and a second end.
6. The device of claim 5 , wherein the first end of the intrauterine balloon is angled away from the longitudinal axis.
7. The device of claim 5 , further comprising an inflation valve positioned through the handle and communicatively coupled to the intrauterine balloon.
8. The device of claim 5 , further comprising a dye injection port positioned through the handle and communicatively coupled to the intrauterine balloon.
9. A uterine manipulator device comprising:
an elongated cannulated manipulator tube comprising a first end and a second end, wherein the first end includes a handle positioned thereon;
a cervical cup having a top portion of a first diameter and a base portion of a second smaller diameter, the base portion being positioned closer to the handle as compared with the top portion, wherein:
the base portion includes a hole formed therein having a perimeter including a first end and a second end, the first end of the perimeter positioned closer to the handle as compared with the second end of the perimeter, and including a longitudinal axis positioned therethrough;
the second end of the perimeter is angled away from the longitudinal axis and the first end of the perimeter is parallel to the longitudinal axis; and
the elongated cannulated manipulator tube is positioned through the hole in the cervical cup;
a retention mechanism comprising a retention ring positioned on the elongated cannulated manipulator tube adjacent to the cervical cup and a ring of heat shrink positioned on the elongated cannulated manipulator tube adjacent to the retention ring, wherein the ring of heat shrink extends longer in an axial direction than the retention ring, and wherein, the retention ring is configured to prevent detachment of the cervical cup from the manipulator tube; and
an intrauterine balloon positioned on the second end of the elongated cannulated manipulator tube and having a first end and a second end, wherein the first end of the intrauterine balloon is angled away from the longitudinal axis; and
further comprising an inflation valve positioned through the handle and communicatively coupled to the intrauterine balloon.
10. The device of claim 9 , wherein the first end of the elongated cannulated manipulator tube is nonlinear.
11. The device of claim 9 , further comprising a vaginal cup positioned closer to the handle than the cervical cup on the elongated cannulated manipulator tube, wherein the vaginal cup includes a top portion with a first diameter and a base portion with a second smaller diameter, and wherein the vaginal cup is configured to maintain pneumoperitoneum during use.
12. The device of claim 11 , further comprising a locking assembly positioned closer to the handle than the vaginal cup configured to lock the cervical cup and vaginal cup in place during use.
