Needle guidance system

A guidance system, comprising:

• an attachment mechanism configured to be removably attached to an imaging device;
• and
• a first guidance mechanism for guiding an intervention device, the first guidance mechanism being attached to a first side of the attachment mechanism;
• a second guidance mechanism for guiding the intervention device, the second guidance mechanism being attached to a first end of the attachment mechanism such that the first guidance mechanism is at a right angle with respect to the second guidance mechanism;
• wherein each of the first guidance mechanism and the second guidance mechanism includes a guide member having opening and a slot extending from the opening, wherein the slot is perpendicular to a longitudinal axis of the guide member, wherein the intervention device is insertable through the opening of the guide member, wherein the guide member of each of the first guidance mechanism and the second guidance mechanism is adjustable along an arcuate path between a plurality of angular positions so as to adjust an angular orientation of the intervention device;
• and,
• wherein the guide member of each of the first guidance mechanism and the second guidance mechanism includes a locking mechanism and a release mechanism extending from the locking mechanism;
• wherein, in a locked position, the locking mechanism is in a lowered position and the release mechanism is in a raised position such that (1) movement of the guide member is restricted and (2) the release mechanism extends perpendicularly across the slot to prevent radial release of the intervention device through the slot;
• and,
• wherein, in an unlocked position, the locking mechanism is in a raised position and the release mechanism is in a lowered position such that (1) the guide member is freely movable and (2) the release mechanism is pivoted downwardly so as to expose the slot to allow radial release of the intervention device through the slot.
