A fornix manipulator includes a collar and stabilizer. The collar has a first end and a second end, the second end having an opening and diameter greater than the first end and the first end having an opening to receive a cervix into the collar. The stabilizer has a base portion defining a guide hole and a plurality of prongs extending from the base portion to contact the first end of the collar.

What is claimed is: 
     
         1 . A collar, comprising:
 a first end including a rim to define a first opening adapted to receive a cervix, the first end having a first diameter positioned on a distal end of the collar, the first end having a first outer rim edge and a second outer rim edge, wherein a gully is positioned between the first outer rim edge and the second outer rim edge, wherein the first diameter extends across the first outer rim edge, wherein the second outer rim edge has a second outer rim edge diameter that is larger than the first diameter,   a second end having a second opening and having a second diameter greater than the first diameter, the second end being positioned on a proximal end of the collar; and   a side wall between the first end and the second end to define an inner cavity between the first opening and the second opening,   the collar having an inner surface adapted to contact a cervix and an outer surface adapted to contact a vaginal wall, wherein the second end is configured to be positioned away from the cervix when the inner surface of the collar contacts the cervix;   wherein the first end and second end form opposing ends of a hollow tunnel adapted to receive the cervix.
