Abstract

A method and apparatus are disclosed for detecting, analyzing and displaying errors in 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 prioritizing errors in a medical treatment system comprising an energy source and at least one associated device, the method comprising:

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

prioritizing one of the at least two errors over at least one other of the at least two errors based on at least one characteristic of each of the at least two errors;

whereby detecting at least two errors comprises 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 or expected parameters, or both.

2. The method of claim 1, wherein each of the errors is prioritized during the step of prioritizing at least one of the at least two errors.

3. The method of claim 1, wherein the characteristic comprises a factor associated with resolving each of the at least two errors.

4. The method of claim 1, wherein the characteristic comprises a severity of each of the at least two errors.

5. The method of claim 3, wherein the factor associated with resoling each of the at least two errors comprises a complexity of resolving each of the at least two errors.

6. The method of claim 3, wherein the factor associated with resoling each of the at least two errors comprises a degree to which resolving each of the at least two errors will resolve another error.

7. The method of claim 1, whereby at least some of the expected measurements and expected parameters are responsive to manual changing.

8. The method of claim 1, whereby at least some of the expected measurements and expected parameters are responsive to a mode of operation of the energy source.

9. The method of claim 1, whereby at least some of the expected measurements and expected parameters are responsive to measurements input into the system.

10. The method of claim 1, whereby at least some of the expected measurements and expected parameters are responsive to said first or second errors.

11. The method of claim 1, comprising classifying the at lease two errors in response to specific values of the input measurements, output measurements, and configuration parameters used in the detection of said errors.

12. The method of claim 1, wherein the step of prioritizing comprises referencing predetermined criteria for assigning a priority to each of the at least two errors.

13. The method of claim 1, wherein the step of prioritizing is responsive at least in part to an order in which the at east two errors were detected.

14. The method of claim 1, wherein the energy source is a radio-frequency generator.

15. The method of claim 1, further comprising a step of prioritizing a response to the higher priority error relative to a response to any other error.

16. The method of claim 15, wherein an error message responsive to the higher priority error is displayed such that it at least partially obscures an error message responsive to a lower priority error.

17. The method of claim 1, wherein the energy source comprises a plurality of inputs.

18. The method of claim 17, wherein the plurality of inputs is selected from the group consisting of inputs from measuring devices and inputs that relay information on the type and quantity of any devices attached to the energy source.

19. The method of claim 17, wherein at least two errors comprises at least two errors responsive to signals received substantially concurrently from at least two of the plurality of inputs.

20. The method of claim 4, wherein an error that is more complex to resolve is prioritized over an error that is simpler to resolve.

21. A method of prioritizing errors in a medical treatment system comprising an energy source and at least one associated device, the method comprising:

detecting at least two errors in the operation of at east one of the energy source and the at east one associated device;

prioritizing one of the at least two errors over at least one other of the at least two errors based on at least one characteristic of each of the at least two errors; and

outputting a display of the at least two errors based on their relative priority;

wherein outputting a display comprises displaying the at least two errors such that the display of the higher priority error at least partially obscures the display of a lower priority error.

22. The method of claim 21, wherein resolving the higher priority error results in the display of the lower priority error becoming unobstructed.

23. A method of prioritizing errors in a medical treatment system comprising an energy source and at least one associated device, the method comprising:

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

prioritizing one of the at least two errors over at least one other of the at least two errors based on at least one characteristic of each of the at least two errors;

wherein the one of the at least two errors s related to a first parameter of energy delivery, and wherein the at least one other of the at east two errors is related to a second parameter of energy delivery different than the first parameter of energy delivery, and wherein the one of the errors is prioritized over the at least one other of the at least two errors based on a relative severity of the errors.
