<p>A unique adjustable biopsy needle-guide device is provided which allows it to be inserted accurately at a selected anatomic site; to be secured in an engaged position; to be disengaged on-demand into a movable form; and to be repositioned at will. The guide device comprises a cannula (12) with multiple wires (40 and 50) and sliding member elements (30 and 32) as a preassembled unit which can be sterilized and conveniently stored until required for use by the physician. The needle-guide serves as a guide-post for the surgeon to remove small or deep seated lesions or for precise placement of biopsy needles at the target site.</p> |
