Artificial joint replacements must be installed accurately to ensure proper biomechanics. Proper installation requires cutting precise shapes out of bone. The Precision Freehand Sculptor (PFS) is a handheld tool to assist the surgeon in accurately cutting these shapes. Its rotating cutter only allows the surgeon to remove waste bone; the cutter turns off when it hits good bone. Thus the surgeon can use the PFS freehand while it automatically restricts the cut to the proper shape.
