Abstract

A method and apparatus are disclosed for detecting, analyzing and displaying errors in a energy source of a medical treatment system. Detected errors are analyzed to define further errors. Errors may be classified, for example, in response to severity, and prioritized. Prioritization may depend on a scope of the error, an order of occurrence, importance, or other factors.

Claims

1. A method of classifying errors in a medical treatment system comprising an energy source having a plurality of modes of operation and at least one associated device, the method comprising the steps of:

detecting at least one error in the operation of at least one of the energy source and the at least one associated device; and

assigning a classification to the at least one error to determine a response of the energy source to the at least one error, the classification being dependent upon a current mode of operation in which the energy source is being operated when the at least one error is detected, such that the at least one error would be assigned a different classification if detected in at least one of the plurality of modes of operation other than the current mode of operation.

2. The method of claim 1, wherein the step of detecting at least one error comprises the sub-step of:

comparing at least one of input measurements, output measurements, and configuration parameters for the operation of the energy source and the at least one associated device, with respective expected measurements and expected parameters.

3. The method of claim 2, wherein at least some of the expected measurements and expected parameters are responsive to manual changing.

4. The method of claim 2, wherein at least some of the expected measurements and expected parameters are responsive to the current mode of operation of the energy source.

5. The method of claim 2, wherein at least some of the expected measurements and expected parameters are responsive to measurements input into the system.

6. The method of claim 2, wherein at least some of the expected measurements and expected parameters are responsive to the at least one error.

7. The method of claim 2, wherein the step of assigning a classification comprises classifying the at least one error in response to specific values of the input measurements, output measurements, and configuration parameters used in the detection of the at least one error.

8. The method of claim 1, further comprising a step of outputting a display of at least one of the at least one classified errors.

9. The method of claim 1, wherein the step of assigning a classification comprises classifying the at least one error based on a severity of the at least one error.

10. The method of claim 1, wherein the plurality of modes of operation comprises at least one energy delivery mode and at least one mode in which energy is substantially not delivered, and whereby an error detected during the energy delivery mode is assigned a classification different than the classification assigned to the same error when detected in the mode in which energy is substantially not delivered.

11. The method of claim 1, wherein the medical treatment system is used in a treatment procedure, and wherein the classification of the at least one error is responsive to progression through the treatment procedure.

12. The method of claim 1, wherein the at least one error comprises at least two errors, and wherein two or more of the at least two errors are substantially identical and wherein one of the two or more substantially identical errors is detected while the energy source is in a first mode of operation and another of the two or more substantially identical errors is detected while the energy source is in a second mode of operation.

13. The method of claim 1, further comprising a step of responding to the at least one error, wherein the response to the at least one error is at least partially dependent on the classification of the at least one error.

14. An energy source for delivering energy to at least one associated device, the energy source having a plurality of modes of operation and comprising an error detecting unit for:

detecting at least one error in the operation of at least one of the energy source and the at least one associated device; and

assigning a classification to the at least one error to determine a response of the energy source to the at least one error, the classification being dependent upon a current mode of operation in which the energy source is being operated when the at least one error is detected such that the at least one error would be assigned a different classification if detected in at least one of the plurality of modes of operation other than the current mode of operation.

15. The energy source of claim 14, wherein the error detecting unit compares at least one of input measurements, output measurements, and configuration parameters for the operation of the energy source and the at least one associated device, with respective expected measurements and expected parameters.

16. The energy source of claim 14, wherein the error detecting unit is operable to classify the at least one error based on a severity of the at least one error.

17. The energy source of claim 14, wherein the error detecting unit comprises a processor.

18. The energy source of claim 17, wherein the error detecting unit comprises a microprocessor.
