Apparatus and method for biopsy and therapy

1. A biopsy and therapy device comprising:

a needling unit for holding and inserting a biopsy needle;

an imaging module comprising an ultrasound probe and an actuator for moving the probe in a reciprocal action;

a first arcuate slide;

a second arcuate slide in sliding engagement with the first actuate slide and a linkage to which the first arcuate slide is mounted;

said linkage arranged to move the first and second arcuate slides within a vertical plane;

said needling unit mounted to said first and second arcuate slides, wherein the first and second arcuate slides are mounted perpendicular to each other so as to rotate the needling unit about respective first and second principal axes; and wherein the imaging module includes a probe sheath positioned on said probe and arranged to allow relative reciprocal motion with said probe.

2. The biopsy and therapy device according to claim 1 , wherein the first and second arcuate slides are concentric about a pivot point.

3. The biopsy and therapy device according to claim 2 , wherein said pivot point is located at a contact point of the needling unit.

4. The biopsy and therapy device according to claim 1 , wherein each arcuate slide comprises a pair of radial sliding bearings.

5. The biopsy and therapy device according to claim 1 , wherein the first and second arcuate slides form part of a rotary head.

6. The biopsy and therapy device according to claim 1 , wherein the needling unit includes a needle holder for holding said biopsy needle during insertion, said needle holder including a recess for receiving said biopsy needle in a direction transverse to a direction of insertion.

7. The biopsy and therapy device according to claim 1 , wherein said needling unit includes a needle stopper arranged to set a pre-determined depth of penetration of said biopsy needle.

8. The biopsy and therapy device according to claim 1 , further including a drape for covering said biopsy and therapy device, said needling unit including a recess with which the drape is arranged to engage.

9. The biopsy and therapy device according to claim 1 , wherein said biopsy and therapy device is arranged to conduct a biopsy procedure based upon one or more of the parameters: a needle insertion point defined as a coordinate position within said vertical plane, a first angle relative to the first principal axis, a second angle relative to the second principal axis and a depth of penetration of the biopsy needle.
