Liposuction is to use ultrasonic, high-frequency electric field and other physical means to crush the fat, and then insert the liposuction tube into the subcutaneous fat layer through a small incision in the skin, and use the suction of negative pressure to remove the subcutaneous fat accumulated locally in the human body. The purpose of losing weight and improving body shape. Liposuction has become one of the most popular cosmetic surgery operations in the world and my country. There are many methods of liposuction: electronic liposuction, ultrasonic liposuction, electromechanical liposuction and syringe liposuction. At present, the combination of ultrasound and negative pressure is more commonly used, which can avoid the disadvantage that the simple negative pressure liposuction method is not very thorough in fat suction. Liposuction itself is very safe. After more than 30 years of development, the technology has become very mature and stable. Although there are also liposuction surgery that uses traditional methods to remove excess fat, but now hospitals generally perform liposuction through machines. At present, there are the following 5 conventional machine liposuction methods:
- Negative pressure liposuction: This is the earliest method of machine liposuction, which uses negative pressure, specific suction tubes, suction tips and appropriate anesthesia to remove local fat. It is suitable for systemic or local fat accumulation due to various reasons.
- Ultrasound liposuction: the use of ultrasonic energy to selectively destroy fat cells, and then suction the adipose tissue through negative pressure. It is divided into in vivo ultrasound and in vitro ultrasound. It is currently regarded as a relatively safe method.
- Electronic liposuction: use the thermal effect generated by a high-frequency electric field of a certain intensity to heat the adipose tissue, resulting in the rupture of fat cells, which is conducive to suction removal.
- Resonance liposuction: Using the principle of resonance, the pipette under the control of computer fuzzy program generates mechanical resonance waves with the same frequency as the natural frequency of fat cells, which selectively destroys fat cells, facilitates suction removal, and can effectively protect nerves and blood vessels.
- Laser-assisted liposuction: The use of low-energy lasers to liquefy adipose tissue to facilitate suction removal. Although there are various methods of liposuction, its core technology is negative pressure, so we have the term “liposuction” or “liposuction”. Negative pressure liposuction can also be said to be the most mature and widely used one. kind. Other ultrasonic, electronic, resonance and other methods only provide beneficial supplements, such as labor-saving operation, help superficial liposuction, and facilitate skin retraction, but these equipments are expensive, the operation cost is high, and the extracted fat Cells have been destroyed and cannot be reused.
