Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ablation region detection, in particular to an ablation region accurate determination device. BACKGROUND

[0002] In actual clinical medicine, such as in the environment of tumor treatment, ablation therapy is a commonly used treatment method. Ablation is a minimally invasive surgery, which punctures the inside of the tumor through an ablation needle, and causes tumor cells to denature and coagulative necrosis through high temperature. Currently, it mainly relies on real-time guidance by CT scanning, so a good ablation region accurate determination device is particularly important at this time.

[0003] A related academic article of the inventor's team ("Comparison and analysis of treatment methods for primary liver cancer with portal hypertension", Jin Bin et al., Chinese Journal of Practical Surgery, Vol. 33 Supplement (1), pp. 54-46, June 2013) discloses that microwave treatment uses FORSEA MTC-3 cold water circulation type microwave ablation therapy instrument. Under the guidance of ultrasound, the puncture needle is placed in the center of the tumor. For lesions with a diameter of ≤3 cm, single needle puncture and one-time ablation can complete the treatment. For nodules with a diameter of >3 cm, two or more needles can be punctured, and two or more times of ablation treatment can be performed. Liver cancer radiofrequency ablation combined with splenectomy and pericardial vascular disconnection has little effect on liver function, complications, and efficacy similar to surgical resection, and is suitable for patients with small liver cancer or scattered multiple tumors with cirrhosis and portal hypertension.
