Description

TECHNICAL FIELD Embodiments of the present disclosure relate to the field of communication technologies, and in particular, to a radio frequency operation data control method, apparatus, and syringe pump. DESCRIPTION OF THE PRIOR ART During the radio frequency operation, the physical characteristic parameters of the radio frequency operation object may change with the radio frequency operation. If they are not controlled in time, damage to the radio frequency operation object, failure of the radio frequency host and other equipment, abnormal radio frequency operation, and even harm to the radio frequency operator may occur. Chinese Patent Application Publication No. CN110897710A provides a control method and a control system of a pulmonary nerve ablation system, and a computer medium; U.S. Patent Application Publication No. US2020/275971A1 provides a method of body tissue ablation; U.S. Patent Application Publication No. US2008/287944A1 provides a method and apparatus for carrying our thermal ablation of target tissue; and U.S. Patent Application Publication No. US2013/030426A1 provides a catheter adapted for ablation. In the prior arts, the operator usually controls the physical characteristic parameters of the radio frequency operation object by experience, which cannot form an effective protection for the radio frequency operation object, and there are often misjudgments and delays in operation, thereby reducing the effect and safety of radio frequency operation. SUMMARY OF THE DISCLOSURE Methods of surgery or therapy hereafter do not form part of the claimed invention, which is defined by the independent claims. The embodiments of the present disclosure aim to provide a radio frequency operation data control method, apparatus, and syringe pump, which can reduce operational delays and errors caused by human judgment, and can also improve the timeliness, accuracy and pertinence of liquid perfusion during the radio frequency operation and improve the effectiveness and safety of the radio frequency operation. In one aspect, the embodiments of the present disclosure provide an electronic apparatus according to claim 1. In a further aspect, the embodiments of the present disclosure provide a syringe pump according to claim 11. In the embodiments of the present disclosure, when the radio frequency operation task is triggered, the syringe pump is controlled to randomly open one perfusion channel, and perform the perfusion operation through the opened perfusion channel at the preset initial flow rate, and the control mode for the radio frequency operation data is determined. In case of a dual control mode, according to the temperatures of multiple different sites of the radio frequency operation object acquired in real time by the plurality of temperature acquisition devices, the syringe pump is controlled to open or close part or all of the perfusion channels and / or to adjust the flow rates of part or all of the perfusion channels; and when the flow rate reaches the temperature-control limit, the output power of the radio frequency is adjusted to control the temperature. After the temperature control is over, the impedance of the radio frequency operation object is detected. If the impedance value exceeds the preset impedance protection range, the impedance value is adjusted by continuing to adjust the flow rate of the syringe pump, so as to realize the dual control of the temperature and impedance of the radio frequency operation object during the radio frequency operation, improving the effect of radio frequency operation and the safety of radio frequency operation, and to realize the intelligent and dynamic adjustment of multi-channel perfusion of the syringe pump based on the real-time temperature and impedance changes of multiple different sites of the radio frequency operation object. Since the perfusion volume of the syringe pump is adjusted more purposefully and directionally according to the real-time changes of the temperature and impedance values of different sites of the radio frequency operation object, operation delay and operation error caused by human judgment can be reduced, and the timeliness, accuracy and pertinence of liquid perfusion during the radio frequency operation can also be improved, thereby reducing the damage of radio frequency operation to the radio frequency operation object and improving the safety of radio frequency operation.
