Abstract: A motor having an alternating current electrical source, a light power circuitry, a stationary transcutaneous energy transmission coil spaced from a rotatable transcutaneous energy transmission coil, a plurality of phototransistor arrays positioned on a rotatable platform and each phototransistor array corresponds to and rotates in conjunction with an armature winding used in the motor. Each phototransistor array (i) receives an alternating current from the rotatable transcutaneous energy transmission coil, and (ii) charges (a) each armature winding to a constant high voltage when the motor is operating and (b) each phototransistor/MOSFET power source to a desired power level. When the light from the light power circuitry contacts a phototransmitter, the phototransistor array is turned on so the armature winding associated with that phototransmitter generates an instantaneous maximum magnetic field.

Abstract: A surgical system comprising a cannula for an elongate surgical tool that enables a physician to operate on a surgical site within a body from outside the body is described. The cannula supports a pin that is locked and unlocked from a J-shaped channel provided in the sidewall of a sheath for a surgical tool. The sheath prevents the surgical tool, such as a scalpel, from cutting the cannula as it is moved there through to the surgical site. The surgical tool, in turn, is provided with a second J-shaped channel that engages with a pin supported by the sheath for locking and unlocking the tool there from to enable a physician to perform the surgical procedure. One surgical tool is interchangeable with another for performing different tasks at the surgical site during the procedure.
