Embodiment Construction
[0024] Such as figure 1 As shown, a microwave ablation carbonization composition control method based on real-time feedback of tissue temperature includes the following steps:
[0025] S1. Analyze the endothermic rate of the tissue sample by differential scanning calorimetry to obtain a DSC endothermic rate curve;
[0026] S2. According to the endothermic rate curve, obtain the temperature T corresponding to the maximum endothermic rate 1 , the T 1 and tissue carbonization temperature T 2 In comparison, set an appropriate upper temperature threshold T 3 and the lower threshold temperature T 4 ;
[0027] S3. Build a microwave ablation and real-time temperature monitoring system, set the ablation power P and time t, and obtain the temperature T at the energy radiation point of the ablation needle in real time;
[0028] S4. If T≥T 3 , pause the ablation, and record the ablation time t 1 , if T≤T 4 , continue to ablate, superimpose and record the ablation time t 1 , unti...
