Surgical apparatus permitting recharge of battery-driven surgical instrument in noncontact state

A surgical apparatus, comprising:

• a surgical instrument having a rechargeable secondary battery and a treatment section to be electrically driven using said secondary battery, and a capable of being disinfected or sterilized;
• an energy generation unit, located outside said surgical instrument, for recharging said secondary battery;
• an energy radiation unit, incorporated in said energy generation unit, for radiating energy;
• a charging energy production unit, incorporated in said surgical instrument, for receiving the radiated energy without said surgical instrument and said energy generation unit being in electrical contact with each other, and for producing energy with which said secondary battery is recharged;
• and
• wherein said energy generation unit includes a light emission unit, and said charging energy production unit includes a photoelectric conversion unit for receiving light emitted from said light emission unit and photoelectrically converting it.
