Malignant solid tumors work best. They include: liver cancer, lung cancer, brain cancer, breast cancer, pancreatic cancer, thyroid cancer, prostate cancer, kidney and adrenal tumors, abdominal and pelvic tumors, bone tumors, soft tissue tumors, head and neck and skin tumors, metastatic gastrointestinal tumors and other solid tumors, benign tumors and benign proliferative lesions, prostate hyperplasia, benign breast tumors, hemangioma, uterine fibroids, cysts, warts, hemorrhoids, recurrent precancerous lesions, oral leukoplakia, etc. Ar-He knife technology can completely ablate early stage tumors through surgical treatment, and the effect will be better. In the middle and late stage, the tumor is not only confined to the local fluid, but also metastasized to other parts, such as lymph nodes, blood and other organs. It is very difficult to achieve a complete cure for such a tumor. However, we can use Ar-He knife treatment to let patients “coexist” with the tumor, reduce their pain and improve their quality of life. A new breakthrough in tumor treatment: Ar-He knife is characterized by its ability to lower the temperature to a very low level and is a purely physical method. It can lower the temperature to about 150 degrees below zero in less than a minute, and it can also quickly re-temperature after freezing, such as raising the temperature to 20-30 degrees above zero in less than a minute, and the temperature difference can reach about 180 degrees. Just like when we take frozen meat out of the freezer and put it into hot water quickly, we see the surface of the meat turns white, which means the tissue is denatured and the cells start to die. Tumor is caused by excessive proliferation of uncontrolled cells. In cryotherapy, we freeze the local cells by freezing them and expand them to the surrounding area through cellular fluid and intercellular bridges, just like dominoes, covering the local fluid and making the tumor cells die quickly. Matching of treatment There are two issues involved in the treatment process, the first one is how we can treat the tumor site more precisely. It is like a GPS device commonly used in cars, we can know exactly where we are. We have to do it under CT or ultrasound guidance, and it can be monitored in real time. The tumor location is determined by imaging, and the device, guided by CT, intervenes the Ar-He knife into the tumor where the tumor is located, after which it is designed according to the size of the tumor, like sometimes one knife, sometimes multiple knives. We cover the range as quickly and comprehensively as possible according to the size of the tumor, and this is the real-time guidance of the Ar-He knife. The second issue is real-time monitoring, for example, how far the tumor is treated, when we terminate the treatment, when we enhance the treatment, we can understand the treatment scope according to the real-time monitoring image on, and adjust the treatment time and the number of treatment knives in time.
