Medical support device

1. A medical support device, comprising:

a first rotational element having a first rotation axis and a first rotational degree of freedom;

a second rotational element having a second rotation axis and a second rotational degree of freedom that is attached to the first rotational element wherein the second rotation axis intersects with the first rotation axis; and

at least one needle guide that is attachable to the second rotational element and is configured to guide the direction of insertion of a needle-like instrument,

wherein the at least one needle guide includes at least one guide portion that guides a first needle-like instrument through a first puncture starting point and guides a second needle-like instrument through a second puncture starting point which is different from the first puncture starting point, wherein,

the at least one needle guide is in a first position when guiding the first needle-like instrument and in a second position when guiding the second needle-like instrument, or

a first needle guide includes a first guide portion that guides a needle-like instrument through the first puncture starting point and a second needle guide includes a second guide portion that guides a needle-like instrument through the second puncture starting point.

2. The medical support device according to claim 1 , comprising at least a first needle guide and a second needle guide that simultaneously or sequentially attach to the second rotational element.

3. The medical support device according to claim 2 , wherein the first needle guide and second needle guide each have visible or electronic identification markers that distinguish the needle guides.

4. The medical support device according to claim 1 , wherein the first puncture starting point and the second puncture starting point are different due to different angles of insertion of the at least one needle guide in the first position and the second position.

5. The medical support device according to claim 1 , wherein different location of the first puncture starting point and the second puncture starting point is due to different heights of the at least one needle guide or guides above the plane defined by the first and second puncture starting points in the first position and the second position.

6. The medical support device according to claim 1 , further comprising an angle calculation unit configured to determine possible angles of the two rotational elements on the basis of specified target positions and the arrangement of two rotational elements and the at least one needle guide.

7. The medical support device according to claim 6 , further comprising an interference analysis unit configured to determine, with respect to the specified different target positions, straight lines showing insertion directions from the possible angles of the two rotational elements with respect to each target position found by the angle calculation unit, and to determine such combinations of insertion directions without interference that the distance between straight lines is greater than or equal to the diameter of the needle-like instrument used.

8. The medical support device according to claim 7 , wherein the interference analysis unit selects a combination of insertion directions that is largest in the distance between straight lines or any one combination from the combinations of insertion directions without interference.

9. The medical support device according to claim 7 , further comprising a presentation unit configured to present the combinations of insertion directions without interference.

10. The medical support device according to claim 6 , wherein the medical support device comprises the two or more needle guides facing in different directions at the same time, and one of the two or more needle guides facing in different directions faces in a direction passing through the intersection of the rotation axes of the two rotational elements, and the others face in such a direction that the distance from the intersection is greater than or equal to the diameter of the needle-like instrument used.

11. The medical support device according to claim 1 , wherein the needle guide has a degree of freedom, and the at least one needle guide is configured for changing the direction in which an instrument is guided.

12. The medical support device according to claim 1 , wherein the at least one needle guide is configured to release the needle-like instrument after insertion.

13. The medical support device according to claim 1 , wherein the two rotational elements each have a position detection unit.

14. The medical support device according to claim 13 , wherein at least one of the two rotational elements has a drive unit, and each rotational element is moved to an angle that is found by the angle calculation unit and selected by the interference analysis unit, on the basis of position information obtained by the position detection unit.

15. The medical support device according to claim 1 , further comprising a medical imaging machine, and at least three markers that can be imaged by the medical imaging machine.

16. A medical support device, comprising:

at least one rotatable portion having at least one rotational degree of freedom and

at least one needle guide attached to the rotatable portion and having a guide portion, which is configured to:

(a) guide the direction of insertion of a needle-like instrument and

(b) separate from the needle-like instrument after insertion of the needle-like instrument,

wherein the guide portion, when the needle guide is positioned in a first position, is configured to guide the needle-like instrument to a first puncture starting point

wherein the guide portion, when the needle guide is positioned in a second position, or wherein the guide portion of a second needle guide is configured to guide the needle-like instrument to a second puncture starting point which is different from the first puncture starting point.

17. The medical support device according to claim 16 , wherein the guide portion is configured to separate from the needle-like instrument via movement out of a notch in the guide portion.

18. A method comprising:

attaching a medical support device to a patient, wherein the medical support device comprises a first rotational element, second rotational element, and at least two needle guides,

defining at least a first location and a second location in the patient for therapeutic intervention based on an image data,

attaching a first needle to a first needle guide,

attaching the first needle guide to the medical support device,

instructing the medical support device to rotate the first rotational element and the second rotational element to a position defined by the first location for therapeutic intervention,

inserting the first needle into the patient,

releasing the first needle from the medical support device,

attaching a second needle to a second needle guide and attaching the second needle guide to the medical support device,

instructing the medical support device to rotate the first rotational element and the second rotational element to a position defined by the second location for therapeutic intervention,

inserting the second needle into the patient, wherein the second needle does not contact the first needle during insertion into the patient, and

releasing the second needle from the medical support device.
