Uterus-manipulator

1. A micro-invasive medical instrument, comprising:

a shaft with a distal segment;

an end balloon on a distal end of the shaft;

a supporting balloon on the shaft, which is at a distance from the distal end of the shaft;

a proximal segment of the shaft;

a coupling releasably coupling the distal segment with the proximal segment; and

a joint positioned between the proximal segment and the distal segment of the shaft, said joint is articulable to provide anteversion and retroversion;

wherein the end balloon completely encloses the distal end of the shaft; and

wherein the end balloon and the supporting balloon are positioned on the distal segment of the shaft.

2. The instrument according to claim 1 , further comprising:

a lateral aperture on the shaft between the end balloon and the supporting balloon, through which a liquid is conducted or an object can be pushed out of the shaft to the outside of the shaft.

3. The instrument according to claim 1 , further comprising:

a first channel in or on the shaft, whose lumen on the distal end is connected with the inside of the end balloon; and

a second channel in or on the shaft, whose lumen on the distal end is connected with the inside of the supporting balloon.

4. The instrument according to claim 1 , wherein the radius of curvature on the distal end of the shaft is equal to at least a fourth of the diameter of the shaft.

5. The instrument according to claim 1 , wherein the instrument is a uterus manipulator.

6. A distal segment for a micro-invasive medical instrument, comprising:

a shaft segment;

an end balloon on a distal end of the shaft segment;

a supporting balloon on the shaft segment, which is at a distance from the distal end of the shaft segment;

a coupling releasably coupling the distal segment with a proximal shaft segment; and

a joint positioned between the proximal shaft segment and the distal segment, said joint is articulable to provide anteversion and retroversion;

the end balloon and the supporting balloon are positioned distal to the joint;

wherein the end balloon completely encloses the distal end of the shaft segment.

7. The distal segment according to claim 6 , further comprising:

a lateral aperture on the shaft segment between the end balloon and the supporting balloon, through which a fluid can be conducted or an object can be pushed out of the shaft segment to the outside of the shaft.

8. The distal segment according to claim 7 , further comprising:

a first channel in or on the shaft segment, whose lumen is connected on the distal end with the inside of the end balloon; and

a second channel in or on the shaft segment, whose lumen is connected on the distal end with the inside of the supporting balloon.

9. The distal segment according to claim 6 , wherein all radii of curvature on the distal end of the shaft segment are equal to at least a fourth of the diameter of the shaft segment.

10. The distal segment according to claim 6 , wherein the distal segment is configured for one-time use and subsequent disposal.
