Abstract

A system and method for transferring power includes a power transmitting unit for transmitting power and a power receiving unit for receiving power from the power transmitting unit. The power transmitting unit may be positioned outside a human body and the power receiving unit is located on an intrabody instrument adapted to be movable from the outside of the human body to inside the human body. The intrabody instrument may be a medical instrument connected to or incorporated within a robotic arm. The power transmitting unit may wirelessly transfer power to the power receiving unit in a continuous, non-interrupted manner.

Claims

1. A system for transferring power, the system comprising:

a power transmitting unit for transmitting power; and

a power receiving unit for receiving power from the power transmitting unit;

wherein the power transmitting unit is positioned outside a human body and the power receiving unit is located on an intrabody instrument adapted to be movable from the outside of the human body to inside the human body.

2. The system according to claim 1, wherein the power transmitting unit is connected to an energy source.

3. The system according to claim 1, wherein the intrabody instrument includes at least an energy storage unit and one or more electronic components.

4. The system according to claim 3, wherein the energy storage unit is a battery.

5. The system according to claim 3, wherein the one or more electronic components include control electronics.

6. The system according to claim 5, wherein the control electronics include logic controls and intrabody instrument drivers.

7. The system according to claim 1, wherein the intrabody instrument is a medical instrument used in surgical procedures.

8. The system according to claim 1, wherein the intrabody instrument is a robotic arm.

9. The system according to claim 1, wherein the power transmitting unit wirelessly transfers power to the power receiving unit in a continuous, non-interrupted manner.

10. The system according to claim 9, wherein power is wirelessly transferred by using inductive coupling power transfer methodologies.

11. The system according to claim 10, wherein the inductive coupling power transfer methodologies permit the power transmitting unit and the power receiving unit to share a same inductor-capacitor resonance frequency.

12. The system according to claim 9, wherein power is wirelessly transferred by using radio frequency (RF) power transfer methodologies.

13. The system according to claim 12, wherein the RF power transfer methodologies permit the power transmitting unit and the power receiving unit to operate at a common frequency.

14. The system according to claim 1, wherein if an energy source connected to the power transmitting unit is disconnected, the power receiving unit is automatically energized via an energy storage unit located within the intrabody instrument.

15. The system according to claim 1, wherein the system further includes one or more data communications units for transferring data between the power transmitting unit and the power receiving unit.

16. The system according to claim 1, wherein the intrabody instrument is assembled inside the human body.

17. A system for wirelessly, continuously, and non-interruptedly transferring information, the system comprising:

a transmitting unit connected to an energy source, the transmitting unit configured to transmit the information; and

a receiving unit including an energy storage unit and one or more electronic components, the receiving unit configured to receive the information from the transmitting unit;

wherein the transmitting unit is positioned outside a human body and the receiving unit is operatively associated with a robotic arm adapted to be movable from the outside of the human body to one or more positions inside the human body during surgical procedures.

18. The system according to claim 17, wherein the information includes power data and communication data.

19. The system according to claim 18, wherein the power data and communication data is wirelessly transferred to a plurality of external sources.

20. The system according to claim 18, wherein the power data is wirelessly transferred by using inductive coupling power transfer methodologies, where the transmitting unit and the receiving unit share a same inductor-capacitor resonance frequency.
