Ar-He cryoablation technology, referred to as Ar-He knife, is a minimally invasive, ultra-low-temperature freezing and ablation of tumors in advanced medical technology. Ar-He knife is the crystallization of aerospace guidance technology, that is, argon cold isolation technology applied to the medical field. 1998 through the U.S. FDA approval, IEC and EMC certification, China's Professor Xu Kecheng (President of the International Society of Cryotherapy) since the introduction of ar-helium knife in 1999, there have been more than 20,000 patients with tumors undergoing ar-helium cryoablation treatment, since the development of ar-helium knife, treatment has been more than 10,000 cases. It is clinically confirmed that argon-helium cryoablation therapy can effectively treat solid tumors such as lung cancer, liver cancer, brain tumor cancer and breast cancer. Combined treatment with chemotherapy, radiotherapy, biological therapy and traditional Chinese medicine can achieve satisfactory clinical results.
