Background technique:

Liposuction is a type of body shape sculpture in plastic and cosmetic surgery. The principle of liposuction is to suck out the excess fat from a certain part of the body through negative pressure suction, so as to achieve the purpose of local rapid weight loss. The common parts of whole body liposuction are: face, double chin, neck, shoulders and back, limbs, hands and feet, upper and lower abdomen, side waist, upper buttocks, buttocks reduction and buttock lift.

Liposuction is gradually gaining popularity in major cities. In the early 1990s, liposuction became popular gradually; losing weight through liposuction has become a common thing, and it has become one of the most routine items of plastic surgery, like double eyelid surgery and rhinoplasty. There are many methods of liposuction at present, such as electric method, syringe method, ultrasound, resonance liposuction, Korean layered liposuction, and electronic liposuction.

The traditional way of liposuction is to cut a small hole in the surgical site, insert the liposuction needle into the fat layer, and then use the negative pressure of the liposuction machine to suck the fat out. Because the diameter of the needle tube of the liposuction needle is 2.5mm, and the fat layer is thick, it is not easy to be sucked out. The traditional operation using the liposuction needle requires the doctor to hold the liposuction needle before and after the operation. For this reason, the operation generally takes a long time, and the pressure on the arm muscles caused by the doctor's long-term hand work can make the doctor feel fatigued.

In the prior art, the Chinese Patent Publication No. CN205549083U discloses a liposuction needle with a rotating function, which includes a mounting shell, a hollow motor, a connecting head, a needle tube, a liposuction hole, a scraper, a liposuction tube, Negative pressure pump, this liposuction needle with rotating function, firstly insert the needle tube into the inside of the human body, start the hollow motor, the hollow motor drives the needle tube to rotate, and under the action of the scraper, the fat can be scraped off, and then the negative pressure pump is started, The negative pressure pump generates a vacuum inside the installation casing and the inside of the needle tube through the liposuction tube, and extracts the fat inside the human body through the liposuction hole; the Chinese patent application with publication number CN203836552U discloses a dual-channel control liposuction device, including a shell body, piston and plunger; the casing has a connected piston cavity and a plunger cavity, the diameter of the piston cavity is larger than that of the plunger cavity; the piston is connected with the plunger, and the two are in sliding sealing cooperation with the piston cavity and the plunger cavity respectively The two ends of the piston cavity are respectively provided with oil ports, the side wall of the plunger cavity has a one-way oil intake port, and the right end has a one-way oil outlet port; the piston moves to the left to drive the plunger to open the oil intake port. When the oil ports at both ends of the piston cavity supply oil alternately, the piston can reciprocate in the piston cavity, and drive the plunger to reciprocate. .

All in all, due to the small diameter of the liposuction needle and the thick fat layer of the human body, it is difficult to suck out the fat layer of the human body. Doctors who hold the liposuction needle for long-term reciprocating liposuction will cause fatigue, and the fatigue of the doctor will affect the effect of liposuction and even cause accidents. The reciprocating liposuction equipment specially used in the beauty liposuction industry has low artificial liposuction efficiency, long liposuction time and poor effect.
