Abstract

A medical instrument configured to be inserted into a body cavity comprises a body comprises a first probe at a first end, the first probe comprising a first cylindrical portion with a first outer circumferential surface of a first diameter; a first circumferential edge at a distal end of the first probe; a first distal lip projecting outwardly from the first outer circumferential surface beyond the first circumferential edge and extending for at least a part of a circumference of the first circumferential edge; and a first marker lip projecting outwardly from the first outer circumferential surface and extending for at least a part of a circumference of the first outer circumferential surface; wherein the first distal lip is positioned distal to the first marker lip; and wherein the body comprises a hollow cavity to enable a second medical instrument to pass therethrough.

Claims

1. A medical instrument configured to be inserted into a body cavity, the medical instrument comprising:

a body comprising a first probe at a first end, the first probe comprising;

a first cylindrical portion with a first outer circumferential surface of a first diameter;

a first distal lip projecting outwardly from the first outer circumferential surface beyond the first circumferential edge and extending for at least a part of a circumference of the first circumferential edge; and

a first marker lip projecting outwardly from the first outer circumferential surface and extending for at least a part of a circumference of the first outer circumferential surface;

wherein the first distal lip is positioned distal to the first marker lip; and

wherein the body comprises a hollow cavity to enable a second medical instrument to pass therethrough.

2. The medical instrument of claim 1, wherein the body further comprises:

a second probe at a second end, the second probe comprising;

a second cylindrical portion with a second outer circumferential surface of a second diameter;

a second circumferential edge at a distal end of the second probe;

a second distal lip projecting outwardly from the second outer circumferential surface beyond the second circumferential edge and extending for at least a part of a circumference of the second circumferential edge; and

a second marker lip projecting outwardly from the second outer circumferential surface and extending for at least a part of a circumference of the second outer circumferential surface;

wherein the second distal lip is positioned distal to the second marker lip;

wherein the second end is opposite the first end; and

wherein the first diameter and second diameter are different from each other.

3. The medical instrument of claim 1, wherein the first marker lip is positioned approximately 20 millimeters in a longitudinal direction from the first distal lip.

4. The medical instrument of claim 2, wherein the second marker lip is positioned approximately 20 millimeters in a longitudinal direction from the second distal lip.

5. The medical instrument of claim 1, wherein the first marker lip and first distal lip have respective mid-points that are located in axial alignment.

6. The medical instrument of claim 2, wherein the second marker lip and second distal lip have respective mid-points that are located in axial alignment.

7. The medical instrument of claim 2, wherein the first distal lip and second distal lip have respective mid-points that are located in axial alignment.

8. The medical instrument of claim 1, further comprising a pneumatic plug having a tapered surface configured to pneumatically plug at least a portion of the hollow cavity.

9. The medical instrument of claim 2, further comprising a pneumatic plug having a tapered surface configured to pneumatically plug at least a portion of the hollow cavity.

10. The medical instrument of claim 2, further comprising an intermediate portion that transitions smoothly between the first and second probes, the intermediate portion comprising a central region having an outer diameter less than each of the first diameter and second diameter.

11. The medical instrument of claim 2, further comprising an intermediate portion positioned between the first and second probes, wherein the intermediate portion is cylindrical, the intermediate portion comprising a central region having an outer diameter less than each of the first diameter and second diameter.

12. A double ended medical instrument configured to be inserted into a body cavity, the double ended medical instrument comprising:

an elongate body comprising;

a first cylindrical segment positioned at a first end of the body;

a second plurality of graduated cylindrical segments positioned between the second cylindrical segment and the central cylindrical segment;

wherein the first cylindrical segment, second cylindrical segment, and central cylindrical segment each have different outer diameters, with the central cylindrical segment having the largest outer diameter;

wherein the first plurality of graduated cylindrical segments comprise outer diameters larger than the first cylindrical segment, but smaller than the central cylindrical segment;

wherein the second plurality of graduated cylindrical segments comprise outer diameters larger than the second cylindrical segment, but smaller than the central cylindrical segment; and

wherein the first cylindrical segment, second cylindrical segment, central cylindrical segment, first plurality of graduated cylindrical segments, and second plurality of graduated cylindrical segments are positioned collinearly.

13. The double ended medical instrument of claim 12, wherein the first cylindrical segment comprises an outer diameter configured to be smaller than an undilated diameter of a human cervical canal.

14. The double ended medical instrument of claim 12, wherein the first cylindrical segment comprises an outer diameter of approximately two millimeters.

a second port extending from the front surface of the disc to the rear surface of the disc, the second port having an inner diameter of a size to enable a tail of a pig to pass therethrough to anchor the cylindrical disc in relation to the pig.

20. The double ended medical instrument of claim 19, wherein the cylindrical disc further comprises a hollow tube extending from the front surface of the disc, the hollow tube positioned collinearly to the first port.

16. A double ended medical instrument configured to be inserted into a body cavity, the double ended medical instrument comprising:

a body comprising a probe at a first end, the probe comprising;

a cylindrical plug portion with an outer circumferential surface of a first diameter;

a circumferential edge at a distal end of the probe; and
