Specifically, as an optional embodiment, the liposuction device is a hydrodynamic force assisted liposuction system, and the needle body is connected with the liposuction device through a liposuction handle and a pipeline. In the embodiment, the liposuction device can select a Body-jet hydrodynamic assisted liposuction system which is connected with the liposuction needle through a liposuction handle and a pipeline and provides suction power for the liposuction needle, and the simultaneous suction is realized through the suction hole 2 on the needle Body 1. By means of the hydrodynamic liposuction system, the nervous system and blood vessels can be further guaranteed not to be damaged, the whole liposuction process is clear and visible, only preset liposuction cells are extracted, damage to the inside of the skin is weak, and skin necrosis cannot occur. The Body-jet hydrodynamic assisted liposuction system is a mature technology in the prior art, and the structure of the Body-jet hydrodynamic assisted liposuction system is not described in detail herein.

In order to prevent the unevenness of the skin after operation, as an alternative embodiment, the needle body 1 of the present embodiment has a non-porous surface on the side facing the epidermis layer 6, in other words, the spiral suction holes 2 do not completely cover the periphery of the needle body 1, and at least a part of the periphery of the needle body 1 is reserved for facing the dermis layer 7 side (i.e. the side far from the deep layer) when extracting fat cells, so that the superficial fat providing nutrition to the dermis layer 7 can be reserved, which is beneficial to protect the flatness of the superficial fat.

With reference to fig. 3, the structure of the liposuction needle in this embodiment enables tumescent liquid, flushing liquid, and the like to be injected into a body in a slightly thin sector shape during an operation, so that injection efficiency of the tumescent liquid can be improved, injection amount of the tumescent liquid can be reduced, injection amount of the tumescent liquid is small, tissue tumescence degree is low, accuracy of the operation can be reduced, and the problem of unevenness after the operation can be reduced; normal saline, adrenalin, tumescent liquid and the like are prepared to enter between fat cells and not enter into the cells, so that the effects of less injury, milder effect and high efficiency are achieved.

Referring to fig. 4, when deep fat is extracted, the non-porous surface faces the side of the reserved nutritive fat layer 5 (shallow fat region), and the structure of the upper and lower difference surfaces more strictly ensures the flatness of the shallow fat.

As an alternative embodiment, the number of suction holes 2 in this embodiment is 3-5. Preferably, the number of the suction holes 2 in the present embodiment is four, and the four suction holes 2 are spirally distributed at 3/4 on the periphery of the needle body 1, so that the fat extraction amount per unit time of the liposuction needle can be increased to four times of the fat extraction amount in the prior art.

As an alternative embodiment, the diameter of the suction hole 2 of the present embodiment is 1.8mm to 2.0 mm. Further preferably, the aperture of the suction hole 2 in this embodiment is as small as 1.8mm, which can further reduce the damage caused by the needle while increasing the amount of fat absorption per unit time, compared to the large aperture in fig. 1 in the prior art.

As an alternative embodiment, the needle body 1 has a diameter of 1.8 mm. Due to the spiral suction hole structure, the diameter of the needle body can be reduced from 5mm to 1.8mm, so that the wound is reduced.

As an alternative embodiment, referring to fig. 3, a plurality of suction holes 2 are spirally distributed on the periphery of the needle body with the axial direction of the needle body as the center, clockwise or counterclockwise, starting from the needle head position of the needle body 1. The needle body with the structure can enable swelling liquid and the like to be injected into the fat layer in a slightly thin fan-shaped manner, and the using amount of the swelling liquid is reduced.

As an alternative embodiment, the needle body 1 is cylindrical hollow.

Example 2

In the multidimensional liposuction method, the spiral surface sucks deep fat, the non-porous surface protects the superficial skin fat from being damaged, the superficial skin fat can fully supply nutrients required by the skin, the elasticity and luster of the skin are maintained, and needle eyes are hardly seen after operation. The diameter of the existing conventional needle is 4-5mm, the incision is sutured after operation, and the stitches can be removed after 7 days.

As an alternative embodiment, referring to fig. 7, in step S1, for most of the suction ring, a single-point fan suction is adopted; the range of suction is marked on the skin by gentian violet, and the surgical site is marked, so that suction correction is facilitated.

Referring to fig. 7, taking the buttocks 9 as an example, the liposuction needle used in this embodiment has a needle diameter of 2mm and a small wound, and when a large part of the suction is performed circularly, the single-point fan-shaped suction mode is adopted, that is, a hidden needle feeding point 8 is selected to feed the needle, and the angle of the needle body 1 is adjusted to form a fan shape to wind the needle feeding point 8 for suction. Compared with the common needle insertion mode, the method can reduce the needle insertion times by more than half, reduce the number of needle eyes, have small wound on the skin and is beneficial to the recovery of postoperative patients.

As an optional implementation manner, before the step S1, a step S0 is further included: accurately testing the body fat content of each part of the human body by adopting a physique measuring system, and making a reasonable, feasible and attractive operation scheme according to actual conditions and the expectation of a patient by checking the fat condition; the patient stands, measures the dimensionality of the operation position, and designs the fat absorption amount and the circumference of each position by combining the body curve.
