An electric motor assembly comprising a housing containing a secondary power source, a motor driver, an electric motor, power sensors to sense faults in a primary power supply and the secondary power source, primary and secondary winding sensors configured to sense faults in a primary winding and a secondary winding of the electric motor, the motor driver comprising a primary controller to control the primary winding in a normal operation mode and a secondary motor controller operatively configured to control at least one of the primary winding and/or the secondary winding in a secondary operation mode, the secondary motor controller configured to drive the motor to a safe position using the secondary winding in the event of a sensed fault in the primary winding and to drive the motor to the safe position using the secondary power source in the event of a sensed fault in the primary power source.

Fault tolerant actuator assembly

A surgical saw and complementary blade. The blade has lock teeth that are more ductal than the cutting teeth. The saw coupling assembly has an anvil and a press. The saw coupling assembly holds the blade to the saw by compressing the saw lock teeth between the anvil and the press so as to result the coining of the lock teeth.

Surgical saw blade with deformable lock teeth and method of manufacturing

A surgical bur with a head that defined a single flute. The flute has a rake surface with a cutting edge and an opposed recess edge. The cutting edge is spaced further from axis of shaft of the bur than the recess edge. The rake surface is often, but not always, planar.

Surgical bur with a single cutting flute

A surgical bur including a shaft with a bur head. A number of flutes are formed on the bur head. Each flute has a cutting edge. Chamfer surfaces form the front, distally directed faces of some of the burs. The flutes without chamfer surfaces having cutting edges emerge from the bur head at locations relatively close to the distal end tip of the head. The flutes over which the chamfer surfaces extend have cutting edges that start, extend proximally rearward, from locations that are, spaced proximal from the distal end tip.
