High-intensity focused ultrasound (HIFU) is a hyperthermia method to coagulate and necrotize tumor tissue in vitro by ultrasonic scalpel. It focuses the ultrasonic energy on one point, so that the tissue temperature at the focus suddenly rises (65℃- 100℃), and the tumor tissue is destroyed by high temperature, thus achieving the purpose of killing tumor cells, while the surrounding normal tissues are not affected.
brief introduction
Although ultrasonic scalpel beauty is called a knife, it is not a real scalpel. Ultrasonic scalpel beauty is to use the principle of ultrasonic thermal energy focusing to bypass the epidermis through the cluster heat transfer mode of lattice. Under the premise of not cutting the epidermis, the ultrasonic scalpel beauty probe sends out matrix molecular energy waves with up to 600-120,000 vibrations per second, which deeply damages subcutaneous cells. At the depth of 1.6-4.5mm, the energy directly acts on the deep fascia, and the RF electric field in the fascia layer forms a focal plane, which strongly impacts the dermal tissue, producing an electric field aggregation effect on the dermal tissue, raising the subcutaneous temperature to about 60-75℃, and determining the effective thermal damage effect of heat on the dermal fiber layer. At the same time, a large number of oral ultrasonic scalpel supplements ACMETEA nutrition. ACMETEA's two repair factors, serous fluid and chitosan oligosaccharide, are natural protective barriers for ultrasonic scalpel surgery, and also trigger the body to start repairing regenerative cells and fascia.
HIFU is a therapeutic device that uses high-intensity focused ultrasound. HIFU is expected to replace the scalpel in some cases and kill tumor cells without surgery, which is probably one of the reasons why some people call it "ultrasonic scalpel".
Ultrasonic scalpel, also known as "ultrasonic cutting hemostatic scalpel", is a new type of surgical instrument that has been used in clinical surgery since the end of 1980s. The scientific name of "ultrasonic scalpel" is high intensity focused ultrasound, which is usually referred to as HIFU in academic circles. We may be familiar with the application of ultrasound in the medical field. For example, many hospitals in China are equipped with B-ultrasound. B-ultrasound is a diagnostic equipment, which uses low-intensity ultrasound.
Ultrasonic surgical equipment was first used in ophthalmology and neurosurgery, mainly for fine segmentation. With the emergence and development of minimally invasive surgery, some people introduced ultrasonic scalpel into laparoscopic surgery, which greatly promoted the development of endoscopic surgery because of less smoke, clear surgical field of vision and less accidental injury to surrounding tissues.
