Water inlet pipe 101 and plasma suction hose 102, it ensure that radiofrequency ablation instrument ion sufficient in ablation procedure
Amount, sufficient ionic weight can ensure the effect of ablation under the weaker environment of voltage.In addition, by plasma water inlet pipe
101 and plasma suction hose 102 be arranged on electrode 50, doctor hold just completed in the lump when electrode 50 does ablation etc. from
The process of sub- physiological saline supply, reduce the operation difficulty of radiofrequency ablation instrument.
Further, radiofrequency ablation instrument also includes display 105, the input and power supply of display 105
The output end of circuit 10, the output end for stimulating control module 30 connect with the output end of ablation control module 40.
Display 105 obtains electric energy from power circuit 10, wherein, the input of display 105 also controls mould with stimulating
The output end electrical connection of the output end and ablation control module 40 of block 30.Under stimulus modality, display 105 can get thorn
Swash the stimulation radio-frequency current that module 32 is sent, by the Treatment Analysis to stimulating radio-frequency current, finally show stimulation radio frequency electrical
The parameters value of stream；Under ablation mode, display 105 can get the ablation radio-frequency current that ablation module 42 is sent,
By the Treatment Analysis to melting radio-frequency current, the parameters value for stimulating radio-frequency current is finally shown.Doctor can pass through
Display 105 learns the parameter value size for stimulation radio-frequency current/ablation radio-frequency current that front electrode 50 is sent, and also allows for each
Parameter value is adjusted.
More than, it is only embodiment of the invention, but protection scope of the present invention is not limited thereto, and it is any to be familiar with
Those skilled in the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be covered
Within protection scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
