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 distal end and a second probe at a proximal end, the first probe comprising;

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

a first lip projecting outwardly from the first outer circumferential surface, extending longitudinally beyond an outer end of the first cylindrical portion, and extending circumferentially about only a portion of the first outer circumferential surface; and

a second lip projecting outwardly from the first outer circumferential surface, extending circumferentially about only a portion of the first outer circumferential surface, and extending circumferentially about the first outer circumferential surface through an arc that subtends an angle of at least 100 degrees;

wherein the first lip is positioned distal to the second lip to raise vaginal tissue to provide a visual landmark at a location distal to the second lip;

wherein the first lip and second lip have respective mid-points that are located in axial alignment;

wherein the body comprises a first hollow cavity to enable a medical device to pass therethrough;

wherein the second probe comprises;

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

a third lip projecting outwardly from the second outer circumferential surface, extending longitudinally beyond an outer end of the second cylindrical portion, and extending circumferentially about only a portion of the second outer circumferential surface; and

a fourth lip projecting outwardly from the second outer circumferential surface, extending circumferentially about only a portion of the second outer circumferential surface; and

extending circumferentially about the second outer circumferential surface through an arc that subtends an angle of at least 100 degrees;

wherein the third lip is positioned proximal to the fourth lip; and

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

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

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

4. The medical instrument of claim 1, wherein sides of the second maker lip transition smoothly from the first outer circumferential surface to limit damage to body tissue when the medical instrument is rotated within the body cavity.

5. 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 first hollow cavity.

6. The medical instrument of claim 1, wherein the first probe comprises a second hollow cavity comprising a size sufficient to fit around a human cervix, enabling the first lip to provide a visual landmark for vaginal tissue as the medical instrument is rotated, the second hollow cavity positioned distally to the first hollow cavity, the second hollow cavity being larger in a transverse direction than the first hollow cavity.

7. The medical instrument of claim 1, 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.

8. The medical instrument of claim 1, 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.

9. The medical instrument of claim 1, wherein an outer edge of the first lip is concentric with the first outer circumferential surface.

10. The medical instrument of claim 1, wherein an outer edge of the second lip is concentric with the first outer circumferential surface.

11. The medical instrument of claim 1, wherein the second lip comprises a tapered shape that is wider adjacent the first outer circumferential surface than at an outer edge of the second lip.

12. The medical instrument of claim 1, wherein the body comprises a surgical grade material.

13. The medical instrument of claim 1, wherein the first probe comprises a length of approximately 85 millimeters.

14. The medical instrument of claim 1, wherein the first diameter of the first outer circumferential surface is approximately 40 millimeters.

15. The medical instrument of claim 1, wherein the first diameter of the first outer circumferential surface is approximately 40 millimeters, and the second diameter of the second outer circumferential surface is approximately 30 millimeters.

16. The medical instrument of claim 1, wherein the first lip is flared outwardly from the first outer circumferential surface by an angle in the range of 130 to 160 degrees.

17. A method of using the medical instrument of claim 1 to perform an oncology procedure, the method comprising:

inserting the first probe of the body of the medical instrument into a vaginal cavity;

positioning the second lip of the first probe to act as a visual landmark that indicates where a surgeon should cut to remove a cuff from the vagina to excise cancer tissue;

cutting vaginal tissue to remove the cuff; and

removing the first probe of the body of the medical instrument from the vaginal cavity.
