What are the surgical weight loss methods?

Long-term obesity will not only affect people's body shape, but also induce many diseases. Therefore, losing weight is what many people pursue. In recent years, there are many ways to lose weight, including surgical weight loss. So what are they?

1. Ultrasonic liposuction

Ultrasonic liposuction is the use of ultrasound to perform liposuction to achieve the purpose of weight loss, also known as ultrasonic lipolysis. Ultrasonic liposuction is a very effective way to lose weight, and the weight loss effect is also very good. Ultrasonic liposuction exists in liquids or biological tissues. However, the intermolecular adhesion of tissues with different densities is different. In low-density fat tissue, the molecular adhesion is weak, and the lower negative pressure generated by ultrasound can produce tissue gaps, which is physically called "cavitation phenomenon." Then use a high-energy negative pressure aspirator to extract the liquefied fat liquid. It is a fat cell crusher.

2. Electric negative pressure liposuction

Electric negative pressure chin liposuction is to make a tiny incision in the skin and use an electric suction device or a special negative pressure liposuction machine to connect the liposuction catheter and different types of metal straws to achieve vacuum negative pressure in a closed container, which is equivalent to one atmosphere (100kPa). For example, the liposuction tube is inserted into the subcutaneous fat layer through the incision to suck out the chin fat bag. Electric negative pressure liposuction is time-consuming and labor-intensive, causes great damage and obvious pain, but the sucked fat can be reused after purification.

3. Electronic liposuction

Electronic liposuction is a liposuction method that uses the high-frequency electric field generated by positive and negative electrodes to destroy, split, and liquefy subcutaneous fat in the body into a milky state, while using negative pressure to extract the broken fat mixture out of the body to achieve the purpose of body shaping. Electronic liposuction is less painful, and the extracted fat is destroyed and cannot be reused.
