<p>An existing gynecologic instrument is capable of rotating the uterus to any of its natural positions within the peritoneal cavity which instrument lessens the danger of damage to vaginal and uterine tissue and which instrument may be adopted for injection of dye into a uterus while the uterus is maintained in any of its natural positions. In the apparatus of the present invention, the improvements reside in means for connecting the tube to the head wherein the tube is fitted or otherwise attached to an end of a piston held in place in the head by a pin which is capable of moving within a groove within the head in such a manner that does not permit removal of the piston from the head as long as the tube is not pivoted about the piston beyond a predetermined degree. <IMAGE></p> |
