Abstract
A shield for controlling a magnetic field emanating from a magnetic in a magnetic medical treatment instrument has the form of a circular shaped band with opposite open ends and a center axis extending perpendicularly between the open ends. The magnet in the magnetic medical treatment instrument moves about an operating table having a surface upon which a patient being operated on by a physician reposes. The circular shaped shield surrounds the magnet and is spaced away from the magnet in a manner to allow the physician to enter the interior of the band and operate on the patient. The band has opposite first and second parallel planar portions. The top surface of the operating table and the first and second planar portions of the band are parallel to each other. The operating table has a length and a width, and the length of the operating table is parallel to the center axis of the band.
