Nowadays, with more and more advanced medical science, we are no longer helpless and at the mercy of fate in the face of cancer. There are many different clinical treatment options for various types of cancer, and patients can flexibly choose treatment options according to their specific conditions. However, it is undeniable that some traditional treatment methods are indeed a great challenge to patients’ body and mind, which not only require considerable physical pain, but also harm patients’ immunity, thus increasing the difficulty of patients’ recovery. High-intensity ultrasound focused tumor treatment system (abbreviated as HEFT) is called “new high-tech technology for non-invasive tumor treatment in the 21st century” by domestic and foreign experts, which has changed the traditional tumor treatment method and made the local treatment of tumor from invasive surgery and interventional treatment to non-invasive treatment. Through the principle of high heat curing, tumors of any size and shape can be removed in just one treatment. Then how does HEFI Ultrasound Focused Knife technology treat cancer? HEFI Ultrasonic Focused Knife mainly focuses 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 high-energy ultrasound in the focal area, it causes coagulative necrosis of tumors, and the cavitation effect ruptures cell membranes and nuclear membranes, causing them to lose their ability to spread. The cavitation effect causes the cell membrane and nuclear membrane to rupture and lose the ability to spread. It is equivalent to performing surgery outside the body to “cut” the cancer mass. The focus of ultrasound entering the body is as big as a soybean, and it burns the tumor layer by layer through the trajectory of point, line, surface and body. 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. The advantages and features of the treatment include: 1. With ultrasound as the source of treatment, the knife effectively uses the physical characteristics of ultrasound in biological tissues, such as good directionality, penetration and focusability, to gather ultrasound energy to form a focal point through physical focusing (similar to the principle of generating huge energy at the focal point by focusing sunlight on the sun), and then destroys cancer cells from outside the body through accurate positioning to cause coagulative necrosis of tumor tissues. It causes coagulative necrosis of tumor tissues, thus losing the ability of proliferation, invasion and metastasis. Generally speaking, tumors will stop growing and gradually be absorbed by human body after treatment with Hepa knife.2. Hepa knife uses ultrasound as the source of treatment and adopts color ultrasound to position and monitor the treatment process in real time, which ensures that the treatment effectively kills cancer cells, and at the same time can selectively destroy small tumor blood vessels within 2mm in diameter, and almost no damage to larger blood vessels. This not only blocks tumor blood supply and starves cancer cells, but also prevents new tumors from metastasizing through blood vessels, and at the same time provides new treatment means for tumor patients who cannot be operated due to their close proximity to large blood vessels.3. Most traditional cancer treatments are destructive surgeries, such as high amputation for osteosarcoma patients, removal of breast for breast cancer patients, and removal of kidney for kidney cancer patients. Since the knife can accurately destroy tumor tissues and protect as much normal tissues as possible, it is conducive to preserving normal tissues and their functions of cancer-stricken organs, making it possible for breast cancer patients to preserve their breasts and limbs for malignant tumor patients to preserve their limbs.4.The knife is a non-invasive treatment, in other words, it is a non-invasive treatment outside the body. No blood transfusion is needed during the treatment process to avoid the occurrence of blood-borne infectious diseases (such as hepatitis B, AIDS, etc.). The patient recovers quickly after treatment and there is no surgical scar. At the same time, because the treatment is done outside the body, the medical implantation of cancer cells is avoided, which is conducive to the local control of tumor and reducing the chance of metastasis.5. As we all know, diagnostic ultrasound is a very safe examination method, which is almost harmless to human body during the examination and can even be used for the examination of fetus. It will not have toxic reactions such as inhibiting bone marrow, causing blood cell reduction, suppressing immune function and causing gastrointestinal symptoms like radiotherapy, which is beneficial for patients to complete various comprehensive treatments. 6. After the treatment, tumor tissues are destroyed and the dead cancer cells keep releasing tumor antigenic substances, which stimulate the patients to produce anti-tumor immunity again, thus may reduce the recurrence and metastasis of tumor and help the human immune system to control the microscopic lesions of the whole body.7. It can effectively treat tumors locally and systemically, thus achieving a more ideal comprehensive treatment effect.8. In contrast to radiation therapy, ultrasound has very little toxic side effects. Therefore, HEFT can treat solid tumors of different sizes, and the largest one can destroy osteosarcoma tissues of 46cm in length and diameter at present. The treatment adopts three-dimensional conformal scanning technology, which can destroy tumors of any shape. The main tumors that are suitable for treatment with Hedgehog knife are: primary or metastatic liver cancer, breast cancer, malignant bone tumors, kidney cancer, pancreatic cancer, soft tissue sarcoma, retroperitoneal tumors, pelvic tumors, bladder cancer, palliative treatment of advanced malignant or metastatic tumors, uterine fibroids, breast fibroids, benign liver tumors, and various solid tumors that can be revealed by B-ultrasound. However, tumors containing gas organs (such as gastrointestinal tract, lung, etc.) and mediastinal tumors are not suitable for treatment with Hepatome.9. Local recurrence after surgical removal of tumors is one of the main reasons for cancer treatment failure. For example, large hepatocellular carcinoma, due to the fact that more normal liver may be removed during the first surgery, makes it difficult to operate again after local recurrence. If live cancer cells are found locally or new cancer foci appear by magnetic resonance imaging (MRI) examination some time after Hepatoma treatment, the treatment can be repeated again until more satisfactory results are obtained. In this case, the pain suffered by the patient during the operation is greatly reduced, not only that, but also that the immunity of the patient’s organism will not be damaged by the Heliofocused knife technology, thus reducing the degree of injury to the patient and creating favorable conditions for the patient’s early recovery. Since its entry into clinical use in December 1997, the clinical application in more than 20 tertiary hospitals in Chongqing, Beijing and Shanghai has shown that HEFI has successfully treated thousands of cases of malignant solid tumors such as liver tumors, while the application of HEFI has also achieved good results in the treatment of benign tumors (such as breast fibroids, uterine fibroids, multiple lipomas, etc.). After the treatment of thousands of tumor patients nationwide, the efficiency rate is 97%, which is highly praised by patients and people from all walks of life.
