Abstract

A wireless foot control apparatus allows an operator to control multiple medical devices during an endoscopic medical procedure. The apparatus comprises a control console with controls designed for foot operation to control various medical devices. The controls include one or more foot pedals and foot switches to control the devices, including a selection switch to allow selection of the device to be controlled at a particular time. The console transmits signals over a wireless medium, to cause a remote receiver unit to select the device to be controlled and to control the selected device over a wired medium, in response to operation of the foot controls. The console may include a rechargeable battery, which may be sealed within the console'"'"'s housing and charged inductively when the console is placed in a charging station. The receiver unit and the charging station can be separate units or integrated within a single housing.

Claims

1. A foot-operated control console to allow an operator to control a plurality of medical devices during a medical procedure, the foot-operated control console comprising:

a plurality of controls designed to be operated by a foot of the operator; and

a set of wireless transmitters that includes at least one wireless transmitter, to transmit a first plurality of control signals over a wireless medium to control the plurality of medical devices during the medical procedure in response to inputs from the plurality of controls;

further comprising a receiver unit for receiving the first plurality of control signals from the at least one wireless transmitter, the receiver unit comprising a sync button, wherein simultaneous actuation of said sync button and said plurality of controls synchronizes said foot-operated control console with said receiver unit.

2. The foot-operated control console as recited in claim 1, further comprising a controller to receive the inputs from the plurality of controls and to provide the first plurality of control signals to the at least one wireless transmitter.

3. The foot-operated control console as recited in claim 1, wherein the plurality of controls includes a selection control to allow the operator to select a device to be controlled from among the plurality of medical devices.

4. The foot-operated control console as recited in claim 3, wherein the receiver unit receives a selection signal based on operation of the selection control and the first plurality of control signals via the wireless medium, and to control the selected device in response to the selection signal and the first plurality of control signals.

5. The foot-operated control console as recited in claim 4, wherein the receiver unit further is to control the selected device via a wired communication medium in response to the selection signal and the first plurality of control signals.

6. The foot-operated control console as recited in claim 5, wherein the receiver unit includes:

a wireless receiver to receive the selection signal and the first plurality of control signals via the wireless medium;

a data communication device to transmit a second plurality of control signals to the selected device over the wired communication medium, based on the first plurality of control signals and the selection signal; and

a controller to control the data communication device in response to the first plurality of control signals and the selection signal, including generating the second plurality of control signals based on the first plurality of control signals so that the second plurality of control signals are compatible with the selected device, as indicated by the selection signal.

7. The foot-operated control console as recited in claim 1, further comprising an internal rechargeable power source to power the foot-operated control console.

8. The foot-operated control console as recited in claim 7, further comprising:

an induction element; and

a charging circuit to control charging of the power source by power induced in the induction element by an external source.

9. The foot-operated control console as recited in claim 1, wherein the plurality of controls includes a foot pedal and a foot switch.

10. The foot-operated control console as recited in claim 1, wherein the plurality of controls includes a plurality of foot pedals and a plurality of foot switches.

11. The foot-operated control console as recited in claim 1, wherein the console transmits a device identifier identifying the console in association with the control signals, the device identifier for associating the foot-operated control console with the unit.

12. The foot-operated control console as recited in claim 1, further comprising a housing to contain the set of wireless transmitters, the housing having an attachment to allow a suction hose to be attached to the housing.

14. The foot-operated control console as recited in claim 1, wherein the plurality of controls includes at least two switches for operation by a foot of an operator, the plurality of controls including a selection control for manual selection of the medical device to be controlled and a separate device control for manually operating the selected medical device, the receiver unit is separate from the foot-operated control console, the receiver unit receives a selection control signal and a device control signal from the at least one wireless transmitter, and the receiver unit provides the device control signal as a wireless signal to the selected medical device for control thereof.

15. The foot-operated control console as recited in claim 14, wherein the receiver unit further comprises indicators for indicating the selected one of said plurality of medical devices.

13. A foot-operated control console to allow an operator to control a plurality of medical devices during a medical procedure, the foot-operated control console comprising:

a plurality of controls designed to be operated by a foot of the operator;

means for transmitting a first plurality of control signals over a wireless medium to control the plurality of medical devices in response to operation of the plurality of controls; and

means for controlling the wireless transmitter in response to operation of the controls;

further comprising receiver means for receiving the first plurality of control signals from the means for transmitting, the receiver means comprising a sync button, wherein simultaneous actuation of said sync button and said plurality of controls synchronizes said foot-operated control console with said receiver means.

16. The foot-operated control console as recited in claim 13, wherein the plurality of controls includes at least two switches for operation by a foot of an operator, the plurality of controls including a selection control for manual selection of the medical device to be controlled and the separate device control for manually operating the selected medical device, the receiver means is separate from the foot-operated control console, the receiver means receives a selection control signal and a device control signal from the means for transmitting, and the receiver means provides the device control signal as a wireless signal to the selected medical device for control thereof.

17. The foot-operated control console as recited in claim 16, wherein the receiver means further comprises indicators for indicating the selected one of said plurality of medical devices.

18. The foot-operated control console as recited in claim 13, wherein the plurality of controls includes a selection control to allow the operator to select a device to be controlled from among the plurality of medical devices.

19. The foot-operated control console as recited in claim 18, wherein the receiver means wirelessly receives a selection signal based on operation of the selection control and the first plurality of control signals, and to control the selected device in response to the selection signal and the first plurality of control signals.

20. The foot-operated control console as recited in claim 19, wherein the receiver means further controls the selected device via a wired communication medium in response to the selection signal and the first plurality of control signals.
