摘要： An electrosurgical system includes an electrosurgical device, one or more temperature sensors associated with the electrosurgical device, a fluid-flow path leading to the electrosurgical device, and a flow-control device disposed in fluid communication with the fluid-flow path. The electrosurgical device includes a probe for directing energy to tissue. The electrosurgical system includes circuitry for detecting bending of the probe. The circuitry alerts the user of excessive bending by activating an alarm, such as an audible alarm, lighting one or more LEDs or other light sources, tactile feedback, or any other means. The electrosurgical system further includes a processor unit communicatively-coupled to the one or more temperature sensors and communicatively-coupled to the flow-control device. The processor unit is configured to control the flow-control device based on determination of a desired fluid-flow rate using one or more electrical signals outputted from the one or more temperature sensors.

The ablation system also includes a controller operable to control the generator and at least one sensor coupled to the ablation probe and the controller that detects an operating parameter of the ablation probe. The controller performs a system check by ramping up an energy output of the generator from a low energy level to a high energy level and monitors an output from the sensor at predetermined intervals of time during the system check to determine an abnormal state. The controller controls the generator to cease the energy output when the controller determines an abnormal state.
