High-energy ultrasound focused tumor treatment system, commonly known as Hefu knife, ultrasound knife, is to use the advantages of large penetration depth of ultrasound, strong pointing and good focusing performance, to gather most of the low-energy ultrasound waves, through the role of water medium coupling, deep inside the human tumor, instantly make the target area tissues warm up to 70-100 C, resulting in high temperature effect, mechanical effect and cavitation effect, so that the target area tissues produce coagulation and necrosis as the main qualitative changes, and lose the ability of proliferation, infiltration and metastasis with little effect on normal tissues outside the target area. It will cause coagulation necrosis of the target tissues and lose the ability of proliferation, infiltration and metastasis, and has little effect on the normal tissues outside the target area. The advantages of high-energy ultrasound focused tumor treatment: The advantages of ultrasound focused knife treatment are that it conforms to the concept of green non-invasive treatment, no surgical incision, no ionizing radiation and radioactive contamination, no general anesthesia is required for patients, and it is suitable for early, middle and late stage patients. Another characteristic of ultrasound focused knife treatment is that its treatment principle determines the same therapeutic effect for benign and malignant tumors of various pathological types, especially in the treatment of breast cancer and uterine fibroids, which have obtained satisfactory therapeutic effects,. Because of the adoption of ultrasound positioning and real-time dynamic monitoring in treatment, it has achieved conformal treatment for different patients, so the treatment has exact destruction of tumor, high treatment efficiency, slight damage to surrounding tissues, low treatment-related complications, and because ultrasound has no dose-accumulation toxicity, treatment can be repeated and patients can be treated on an outpatient basis, which is very convenient. It can be seen that ultrasound focused knife treatment is the best local treatment for tumor with the best safety at present. Our department adopts the leading high-intensity focused ultrasound tumor treatment equipment in China, which is an organic unification of effectiveness and safety and has been certified by SFDA and CE.
