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, ora 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.

Abstract
There is provided a medical support device for holding and positioning a needle. This device is particularly useful for positioning needles in a less invasive puncture treatment. This device comprises two rotational elements and at least one needle guide attached to a rotational element and. The needle guide guides the direction of insertion of a needle-like instrument and includes a guide portion that guides a needle or other needle-like instrument where the puncture point of the needle in a first position is different from the puncture point when the needle guide guides the needle in a second position.

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.

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.
