Abstract

The present invention is a universal limited reuse assembly for an ophthalmic hand piece having a power source for providing power to a tip segment, a controller for controlling the operation of the tip segment, a motor with a shaft, a mechanical linkage interface located on an end of the shaft, an interface for connecting the limited reuse assembly to the tip segment, and a housing at least partially enclosing the power source, the controller, and the motor. The limited reuse assembly is connectable to and removable from two or more types of tip segments. Each of the two or more types of tip segments is configured to perform a different procedure.

Claims

1. A universal limited reuse assembly for an ophthalmic hand piece comprising:

a power source for providing power to a tip segment;

a controller for controlling the operation of the tip segment;

a motor having a shaft;

a mechanical linkage interface located on an end of the shaft;

an interface for connecting the limited reuse assembly to the tip segment; and

a housing at least partially enclosing the power source, the controller, and the motor;

wherein the limited reuse assembly is connectable to and removable from two or more types of tip segments, each of the two or more types of tip segments configured to perform a different procedure.

2. The system of claim 1 wherein the interface is an electrical interface for coupling a heater to the limited reuse assembly.

3. The system of claim 1 wherein the data interface is adapted to receive information from the tip segment.

4. The system of claim 3 wherein the information received is used by the controller to control operation of the motor.

5. The system of claim 3 wherein the information received is used by the controller to control operation of a heater.

6. The system of claim 3 wherein dosage information is transferred from the tip segment to the limited reuse assembly.

7. The system of claim 6 wherein the controller uses the dosage information to control the operation of the motor.

8. The system of claim 1 wherein the motor is a stepper motor.

9. The system of claim 1 wherein the limited reuse assembly further comprises:

an RFID reader located within the housing, the RFID reader adapted to read information from an RFID tag.

10. The system of claim 1 further comprising:

an indicator for indicating a status of the system.

11. The system of claim 10 wherein the indicator is a light emitting diode.

12. The system of claim 1 further comprising:

an input device located on the housing.

13. The system of claim 12 wherein the input device is a switch.

14. The system of claim 12 wherein the input device is a button.

15. The system of claim 1 wherein the limited reuse assembly is capable of being connected to and operating a tip segment that performs a cauterizing procedure.

16. The system of claim 1 wherein the limited reuse assembly is capable of being connected to and operating a tip segment that performs a drug delivery procedure.

17. The system of claim 1 wherein the power source is a battery.

18. The system of claim 1 wherein the controller is adapted to determine a type of tip segment connected to the limited reuse assembly.

19. A universal limited reuse assembly for an ophthalmic hand piece comprising:

a rechargeable battery for providing power to a tip segment;

an electrical interface for connecting the limited reuse assembly to the tip segment;

a controller for controlling the operation of the tip segment;

a motor having a shaft;

a data interface for connecting the limited reuse assembly to the tip segment; and

a housing at least partially enclosing the power source, the controller, and the motor;

wherein the limited reuse assembly is connectable to and removable from two or more types of tip segments, each of the two or more types of tip segments configured to perform a different procedure and further wherein the controller is adapted to determine a type of tip segment connected to the limited reuse assembly by receiving data from the tip segment via the data interface.
