Abstract

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 pair of plastic caps designed to be inserted into the uterine cavity. A cervical cap is secured to this tube to insure that the tube would not extend beyond a certain distance into the uterus. A hollow outer shaft is provided into which the inner tube can be inserted.

Claims

1. A device for the manipulation of the uterus comprising:

an elongated inner tube having a distal end and a proximal end;

an outer cervical cap having a top portion of a first diameter and a bottom portion having a second diameter less than said first diameter, said bottom portion of said outer cap provided with a hole therein;

an inner cervical cap having a top portion of a third diameter and a bottom portion having a fourth diameter less than said third diameter, said bottom portion of said inner cap provided with a hole therein, said inner cap joined to, and provided within said outer cap to form a retractor elevator, said elevator movable on said elongated inner tube; and

an outer hollow shaft having a distal end and a proximal end, provided with a longitudinal groove having a distal end and a proximal end extending from the distal end of said outer shaft to immediately prior to the proximal end of said shaft, said elongated inner tube inserted into said outer shaft during uterine manipulation;

wherein when said device is utilized, said inner cap would surround and support the cervix and said outer cap would stretch the upper vaginal canal.

2. The device in accordance with claim 1, wherein said longitudinal groove terminates at its proximal end with an elongated beaded aperture, the proximal end of said outer hollow shaft provided with a hole enabling said inner tube to move through said beaded aperture and said hole of said outer hollow shaft.

3. The device in accordance with claim 1, further including a disk provided with a hole therein, said disk attached to said bottom portion of said outer cap.

4. The device in accordance with claim 3, wherein said disk is provided with an inner disk made from a firm plastic material and an outer disk, surrounding said inner disk, made from a softer, more flexible plastic material.

5. The device in accordance with claim 3, wherein a cervical stop is permanently affixed to said elongated inner tube close to its proximal end.

6. The device in accordance with claim 5, wherein the proximal end of said inner tube is provided with a first balloon and the distal end of said inner tube is provided with a second balloon.

7. The device in accordance with claim 1, wherein a cervical stop is permanently affixed to said elongated inner tube close to its proximal end.

8. The device in accordance with claim 7, wherein the proximal end of said inner tube is provided with a first balloon and the distal end of said inner tube is provided with a second balloon.

9. The device in accordance with claim 1, wherein the proximal end of said inner tube is provided with a first balloon and the distal end of said inner tube is provided with a second balloon.
