It has changed the traditional tumor treatment method, so that the local treatment of tumor can be directly transferred from traumatic surgery and interventional treatment to non-traumatic treatment through the principle of high intensity ultrasound focused tumor treatment system (abbreviated as “Hai Fu Knife”). Through the principle of high heat curing, tumors of any size and shape can be removed in just one treatment. Liu Yuanshui, Department of Minimally Invasive Oncology, Shandong Qianfushan Hospital The principle of Hefei Ultrasonic Focused Knife is similar to that of the sun focusing on the sun to produce huge energy at the beginning of the focal point, which mainly focuses the low-energy ultrasound outside the body in the process of penetrating tissues, and through the instant high temperature (65℃~100℃) and cavitation effect generated by the high-energy ultrasound in the focal point area, it causes coagulative necrosis of the tumor, and the cavitation effect causes the cell membrane and nuclear membrane to rupture and lose the ability to spread. The cavitation effect causes the cell membrane and nuclear membrane to rupture and lose the ability to spread. This is equivalent to performing surgery outside the body to “cut” the cancer mass. The focus of ultrasound entering the body is the size of a soybean, and the tumor is burned to death layer by layer through the trajectory of point, line, surface and body movement. It does not need to remove part of human body organs and tissues, and patients no longer have to bear the risk and pain of surgery, and there is no physical damage such as incision and bleeding. It only kills cancer cells and does not damage normal cells, which can enhance the immune function of the body instead of reducing it. The whole treatment process is accurately completed under the real-time monitoring of positioning and monitoring system. It is a new technology of surgical tumor treatment in the 21st century, which is non-invasive, non-bleeding, non-scarring, non-traumatic, non-radiation and non-side effects. It realizes the new green treatment method of liver cancer preservation, bone tumor preservation, breast cancer preservation, uterine tumor preservation, uterus preservation, other organ tumor preservation, pain and pain relief, while enhancing immune function. The results of nearly 10,000 cases of domestic treatment show that the non-invasive treatment of tumors with the knife is comparable to the traditional treatment of tumors, and has more unique advantages. The schematic diagram of the complete coverage of tumor target area by the knife Shandong Qianfo Mountain Hospital introduced the world’s most advanced high-intensity focused ultrasound tumor treatment system, the knife, in January 2002, which represents the global trend of tumor treatment. It is computer-controlled and operated, using ultrasound as the energy source, launched from outside the body to inside the body, just like using a convex lens to focus the light of the sun on a piece of paper, it will scorch the paper on the focal point (the temperature of the focal point reaches 65–105 degrees Celsius), and then completely remove the tumor in the body from outside the body without opening an incision, improving the The cure rate and remission rate of tumor patients, improve the quality of life and prolong the survival time. There are many treatment methods for tumors, but the advanced nature of HAVOCAR is to completely treat tumors without damaging the patient’s body, which has the following unique advantages compared with surgery, chemotherapy, x-knife, r-knife and other tumor treatment techniques: 1. It can preserve breast for breast cancer patients, limbs for bone tumor patients, and normal liver tissue for liver cancer patients to the maximum extent. 2.One time treatment: depending on the condition, the tumor can be “removed” at one time. 3.Conformal treatment: Using stereoscopic group conformal scanning technology, conformal “resection” of tumor of any size and shape can be carried out according to surgical principles. 4.Effective treatment: More than 1300 patients have been treated with the knife nationwide, with a clinical efficiency of 97%. The indications of the knife are: primary and metastatic liver cancer, breast cancer, malignant bone tumor, soft tissue sarcoma, kidney cancer, pancreatic cancer, uterine fibroids and hepatic hemangioma and other solid tumors. The treatment of the above tumors has achieved encouraging results; among them, 46 patients with liver cancer, whose tumors were 5~7 cm in size and had lost the chance of surgery, and whose survival period was only 3~6 months according to the traditional theory, had a survival rate of 82% for one year and 73.5% for two years after complete “resection” by Hepatome. After breast-conserving treatment of 52 breast cancer patients and limb-conserving treatment of 47 malignant bone tumor patients, the efficiency of functional examination is 100% and the efficiency of puncture biopsy is 100%, and the local recurrence rate is only 2% and 4% during the maximum 28-month follow-up.
