一种可自适应调节温度的单双极切换射频消融系统研究
Research on a Single and Bipolar Switching RF Ablation System with Adaptive Temperature Adjustment
摘要: 本文介绍了一种新的基于温度，电压，功率三种PID模式控制下的可进行单双极切换的肺部射频消融设备。该射频消融设备采串级PID (比例–积分–微分)控制系统，可以实现对射频消融的速度和深度进行精确的控制和调整，以提高手术效率和准确性。此外，该设备还具有单双极切换功能，根据不同的病灶特征进行选择，适用于肿瘤或其他病变部位的消融治疗。它还集成了先进的温度控制技术，通过消融导管注入生理盐水，能够实时监测组织的温度变化并自动调节功率输出，以确保消融的同时避免局部组织烧灼或损伤。并且进行了活体猪实验拍摄CT。结果表明消融效果良好，消融的范围在3.0~4.5 cm左右，对于肺部临床有一定的参考价值。
Abstract: In this paper, we introduce a new radiofrequency ablation device for lung that can perform single and bipolar switching under the control of three PID modes: temperature, voltage and power. This radio frequency ablation device uses PID (proportional Integral-differential) control system, which can achieve accurate control and adjustment of the speed and depth of radio frequency ablation to improve the efficiency and accuracy of surgery. In addition, the device also has a single-bipolar switching function, which can be selected according to different focal characteristics, and is suitable for ablation therapy of tumors or other pathological sites. It also integrates advanced temperature control technology, injecting normal saline through an ablation catheter, which is able to monitor the temperature changes of the tissue in real time and automatically adjust the power output to ensure ablation while avoiding local tissue burning or damage. A live pig experiment was carried out to take CT measurements. The results showed that the ablation effect was good, and the ablation range was about 3.0~4.5 cm, which was of certain value for lung clinic.
