Radiofrequency ablation has long been an important means of tumor treatment, besides other alternatives like surgical resection, radiotherapy and chemotherapy. For early malignant or benign tumors, a single session of radiofrequency ablation is able to effect a radical cure.

Radiofrequency ablation needle electrode, under image-guide technology such as B-scan ultrasonography or CT scan, can perform precise positioning and puncture of tumor by passing power current at the front end of the electrode to generate radiofrequency that drives high-speed vibration of polar molecules inside the tumor tissue, the frictional heating of which shall cause the temperature high enough to kills tumor cells directly.

Radiofrequency ablation treatment is quite effective, it brings minor injury to patients and a patient can be repeatedly treated. Complete tumor ablation can still be achieved through a second treatment. After radiofrequency ablation, anti-tumor immune response is stimulated, it further removes residual tumor cells and effectively prevent recurrence, with cooperation of body’s immune system.

• Accurate temperature control mode paired with impedance monitoring mode to provide gradual temperature rise to avoid carbonation adhesion, and improve controllability, which results in a more or less spherical ablation zone.
• A temperature-controlled moving shot mode can result in an ablation zone that is more regular and therefore improves the accuracy of ablation.
• Ablation lesion width formed by different temperature setting could cope with various complex lesion environment.
• The temperature-controlled needle tract ablation creates an accurate ablation effect, effectively prevents tumor seeding or metastasis along the needle tract and helps to avoid bleeding or pneumothorax. The system is intelligent in a way by prompting for needle withdrawal upon the appropriate temperature is reached.
