Abstract

A camera system having a camera head with an imaging device and a first connector; a camera control unit with a processor and a second connector configured to removably engage the first connector; and wherein the first connector and the second connector are configured to allow for contactless transfer of data from the camera head to the camera control unit and contactless transfer of power from the camera control unit to the camera head.

Claims

1. A camera system used with an endoscope comprising:

a camera head further comprising;

an imaging device; and

a first connector, the first connector comprising a metal shield and a plurality of extremely high frequency radio transmitters configured to transmit a plurality of channels of data simultaneously;

a camera control unit comprising;

a processor; and

a second connector configured to removably engage the first connector, the second connector comprising a capacitor and a plurality of high frequency radio receivers configured to receive a plurality of channels of data simultaneously; and

wherein the first connector and the second connector are configured to allow for contactless transfer of uncompressed high definition video from the camera head to the camera control unit and contactless transfer of power from the camera control unit to the camera head; and

wherein the first connector and the second connector are configured so that when the first connector is engaged with the second connector, the shield is physically coupled to the capacitor.

2. The camera system of claim 1 wherein the camera head further comprises an illumination system;

and the first connector and the second connector are configured for contactless transfer of power for the illumination system.

3. The camera system of claim 1 wherein the first connector further comprises at least one power receiver coupled to at least one power receiver coil;

and wherein the second connector further comprises at least one power transmitter and at least one power transmitter coil; and

wherein power is transferred between the first connector and the second connector using magnetic field coupling between the at least one power transmitter coil and the at least one power receiver coil.

4. The camera system of claim 3 wherein the first connector further comprises two power receivers, each power receiver being coupled to a separate power receiver coil;

and wherein the second connector further comprises at least two power transmitters, each power transmitter being coupled to a separate power transmitter coil.

5. The camera system of claim 1 wherein data is transferred using near field energy.

6. The camera system of claim 5 wherein the first connector further comprises a plurality of data transfer surfaces and simultaneously transmits data using multiple data paths.

7. The camera system of claim 1 wherein each data channel transfers data at a rate of at least about 0.5 Gbs.

8. The camera system of claim 1 wherein each data channel transfers data at a rate of at least about 2.5 Gbs.

9. The camera system of claim 1 wherein the second connector further comprises a retractable plunger and the first connector further comprises a detent;

and wherein the retractable plunger is engageable with the detent to maintain engagement of the first connector with the second connector.

10. A camera system used with an endoscope comprising:

a camera head further comprising;

an imaging device;

an illumination system; and

a first connector further comprising;

a plurality of extremely high frequency radio transmitters configured to transmit a plurality of channels of data simultaneously;

at least one extremely high frequency radio receiver;

at least one power receiver;

at least one power receiver coil coupled to the at least one power receiver; and

a metal shield;

a camera control unit comprising;
