At the beginning of the new year on January 8, 2022, Tianjin City was attacked by the Omicron variant of the COVID-19 virus, and the alarm was sounded throughout the city overnight. The Tianjin Municipal Government responded quickly and took emergency measures, including suspending classes at all levels of schools and kindergartens, suspending inter-provincial bus services, closing some tourist attractions, and implementing strict management of people leaving Tianjin unless it is necessary.

The severe epidemic has attracted the attention of the whole nation. With the deepening of large-scale nucleic acid testing, local cases continue to increase, and major medical institutions and every medical worker in Tianjin have entered a state of readiness. While supporting the anti-epidemic work, efforts must also be made to maintain normal medical work.

Tianjin Medical University General Hospital, as a leading institution in medical technology and standardized management in Tianjin, not only takes the lead in fighting the epidemic prevention and control, but also ensures the normal medical treatment of patients. The interventional radiology team of the General Hospital has been working overtime to provide timely and efficient treatment plans for cancer patients in need.

On the afternoon of January 10, 2022, experts Fan Yong and Fu Dianxun from Tianjin Medical University General Hospital led a team to use the High Voltage Steep Pulse Minimally Invasive  Therapeutic System independently developed by Shanghai Yuanshan Medical Technology Co., Ltd. They successfully performed tumor Nanoknife ablation surgery for patients through CT-guided puncture.

The surgery officially began at 5 pm, with the patient under general anesthesia. Dr. Fu Dianxun skillfully performed percutaneous puncture and ablation guided by CT. The ablation process went smoothly. After the ablation, a CT enhanced examination was conducted, which showed that the lesion area in the image was of low density, the ablation boundary was clear, and the surrounding blood vessels were intact and unobstructed. This indicates that the tumor ablation was completely successful and the treatment was very successful.

After the operation, when discussing this operation together, Fan Yong and Fu Dianxun, two experts, said that the domestically produced nano-knife has outstanding performance in both energy field stability and real-time parameter monitoring by using superior technology, and this technology has filled the gap of domestic technology and provided a new chance of life for many patients with refractory cancer.
