Filed: 1993-02-23
Granted: 2004-01-06
Abstract: A method and apparatus for knee replacement surgery wherein a femoral provisional component is provided which corresponds to a permanent component to be implanted in a human and which includes means for establishing the correct fit and position of such a component, prior to its implantation, in relation to the soft tissues of the knee before final resection of the anterior femoral surface. The provisional component further includes cutting guide means for such anterior surface resection such that accurate cuts may be made with the provisional component in place. The method involves preparing the distal femoral surface using the femoral intramedullary canal as a constant reference point for posterior and distal cutting guides followed by locating the provisional component by means of a provisional intramedullary stem so that the relationship with the soft tissues of the knee may be accurately established.

Abstract: A control system for dual oven resistance heaters (BAKE, BROIL) has opposite sides of each heater connected to a common side of one of a pair of SPDT switching relays such that no current flows to the heaters when both relays are in a common state of energization/de-energization. A microcomputer receives a signal from the oven temperature sensing and signals separate switching devices to selectively energize/de-energize one of the relays to switch on the desired heater. Separate comparators also receive the temperature sensor signal; and, in the event of failure of the microcomputer or switching devices with a heater "ON", the comparator is operative to bring the relays to acommon state, preventing current flow to either heater.
