In one embodiment, power control unit 142 first has to guarantee the safety of radiofrequency ablation procedures, then guarantees radiofrequency ablation procedures Validity.
Control module 140 further includes alarm control unit 143.Alarm control unit 143 and temperature acquisition module 110 connect It connects.Alarm control unit 143 receives the real-time temperature values that temperature acquisition module 110 handles obtained each target area.Alarm control Unit processed is when there are the upper limit that the corresponding real-time temperature values in target area are more than its corresponding preset temperature range, alarm control 143 alert of unit processed.
In the present embodiment, power control unit 142 and alarm control unit 143 also connect with temperature setting unit 141 respectively It connects.The real time temperature signal for each target area that power control unit 142 is detected according to temperature sampler and corresponding default Temperature range controls the size of the output power of radio-frequency module 130.What alarm control unit 143 was detected according to temperature sampler The real time temperature signal of each target area and corresponding preset temperature range alert.In this manner it is achieved that by radio frequency Ablating device is applied to have corresponding control strategy when different scenes, to meet specific RF ablation requirement.
It should be noted that in other embodiments, temperature acquisition module 110 can not also include Temperature Treatment list Member, for example, power control unit 142, alarm control unit 143 also can handle the real-time temperature of each temperature sampler detection respectively It spends signal and determines that corresponding real-time temperature values, i.e. power control unit 142, alarm control unit 143 can integrate temperature respectively Spend the function of processing unit.
RF ablation device 100 further includes warning device 150, and warning device 150 is for issuing alarm signal.Warning device 150 connect with alarm control unit 143, when there are the corresponding real-time temperature values of temperature acquisition module 110 more than its corresponding When the upper limit of preset temperature range, warning device 150 issues alarm signal according to the warning message of alarm control unit 143.By Doctor judges according to alarm signal.Doctor can control the output power of radio-frequency module 130 by the height of seriousness, For example, the output of cutting radio-frequency module 130, or the output power of radio-frequency module 130 is reduced to respective degrees.In this way, can It is relatively more flexible to be operated by doctor according to situation.Warning device 150 can be alarm lamp.
