Recently, the innovative product Multimodal Tumor Treatment System of Shanghai Magic Medical Technology Co., Ltd. is approved for marketing by China NMPA.

This product is a multimodal treatment system that integrates liquid nitrogen freezing and radio frequency (RF) heating. Through pre-freezing the target lesion, followed by RF heating and precise control of the process, it achieves multimodal tumor ablation where the heating area overlaps with the freezing area, thereby realizing precise treatment of the lesion.

This product overcomes the problem of gas resistance by optimizing the design of the ablation probe, and therefore achieves efficient phase change heat transfer. In the treatment section of the ablation probe, precise measurement and real-time feedback of tumor tissue during the treatment process are achieved by shielding against RF interference. High vacuum technology is used in the non-treatment section of the ablation probe to construct an ultra-thin vacuum insulation layer to shield against RF electromagnetic field, while completely ablating the tumor and minimizing damage to the surrounding tissues. The integrated control system can also realize the visualization of ablation area by precisely controlling the pre-freezing and RF heating processes.

The NMPA will strengthen the post-marketing surveillance of the product to protect the safety of medical devices used by patients.
