What are the blunt needle liposuction methods, their differences, and their pros and cons?

1. Syringe liposuction:

It is a manual operation, which is simple and easy to operate. It uses the negative pressure inside the syringe cavity to suck out only the adipose tissue from the suction site. To put it simply, through one or several needle holes, the prepared swelling solution containing anesthetics is injected into the subcutaneous fat layer, so that the fat tissue is expanded and liquefied, and the liquefied fat is liquefied by means of the negative pressure in the inner cavity of the syringe. Aspirated out of the body

Pros: Less trauma, less bleeding, fewer complications

Disadvantages: Slow liposuction, incomplete liposuction

2. Negative pressure liposuction:

Negative pressure liposuction refers to the application of the principle of negative pressure suction, using a professional metal straw to insert into the subcutaneous skin through a small incision in the skin, while scraping and sucking, the locally accumulated adipose tissue is sucked out

Advantages: less bleeding, less tissue damage, long anesthesia effect, good pain relief, safe and reliable

Disadvantages: scars left after surgery, often uneven after surgery, and long recovery time for skin numbness

3. Electronic Liposuction:

It uses high-frequency electric field thermal effect to destroy fat. During the operation, two electrodes are inserted into the skin tissue, and then the fat is liquefied and sucked out at the same time.

Advantages: Fatty fibrous tissue of various strengths and tenacities can be set according to needs, and different procedures can be selected for targeted treatment.

Disadvantages: The speed of liposuction is slower than that of negative pressure liposuction. At the same time, the sucked fat cannot be reused. The price of machines and consumable materials is more expensive.

4. Ultrasonic liposuction:

The ultrasonic liposuction equipment is used to emit ultrasonic waves of a certain frequency and a certain energy under the skin, so that many gaps are formed in the liquid inside and outside the cells. When these gaps have an "internal explosion", the ultrasonic energy turns around, and finally causes the cells to rupture and be sucked out by negative pressure.

Advantages: no damage to blood vessels and nerves, less bleeding, smooth and smooth skin after surgery, no unevenness

Disadvantages: The fat needs to be emulsified first, and then sucked out by negative pressure, which is time-consuming, and heat is generated during the process of crushing fat, which is easy to damage surrounding tissues

5. Resonance Liposuction:

It is to inject swelling fluid into the deep fat layer to make the fat cells edema and expand, and then expel the fat cells from the body through negative pressure suction.

Advantages: fast liposuction, less bleeding, large amount of liposuction, smooth and smooth skin after surgery

Disadvantages: skin necrosis, hematoma, subcutaneous effusion, delayed wound healing, dull skin sensation, hyperpigmentation, etc. may occur

6. Laser Assisted Liposuction:

The laser beam is placed into the lumen of the suction tube, and the laser cuts off the inhaled adipose tissue and solidifies the nourishing blood vessels of the adipose tissue. At the same time, it has the effect of hemostasis and reduces bleeding. In addition, the laser can stimulate collagen contraction and promote postoperative skin retraction.

Advantages: can reduce operating intensity and reduce damage

Disadvantages: expensive equipment, special training required before surgery, easy to cause skin burns
