Problems solved by technology
[0004] In order to solve the problem that the filler fat particles in the prior art are too large in diameter and can only be applied to relatively loose skin, the present invention provides a small particle fat filler for face lifting, a preparation method and a device. The method of filter screen filtration obtains small particle fat, which effectively solves the problems in the prior art

Embodiment Construction
[0045] The present invention will be further described below in conjunction with the accompanying drawings.
[0046] At present, the traditional fine particle fat extraction requires a 1mm custom-made liposuction tube to absorb fat. This method is very time-consuming and has a low acquisition rate, and because the fat tissue is squeezed when it passes through the fine needle tube, its activity will be affected.
[0047] The face lifting in the present invention refers to the method of improving wrinkles, solving the problem of skin sagging, restoring skin elasticity, and making the face appear youthful through injection filling, surgery and other ways.
[0048] like figure 1 , a device for extracting small-particle fat cells, comprising: a sealed upper cover 1, an upper cell sieve 2, a cylinder body 3, a lower layer cell sieve 4, an openable interface 5, a negative pressure device valve 6, and a device for setting the cylinder body 3 Base 7, negative pressure device 8; wherei...

Abstract
The invention provides a small-granule fat filler for face lifting, a preparation method and device to solve the problem of overlarge diameter of filler fat granules in the prior art. The preparationmethod comprises the following steps: mixing a small-granule fat suspension and PRP in a ratio of 1:(4-6) to form a mixture; and mixing the mixture formed by the small-granule fat suspension and the PRP with SVF-gel, wherein the content of the SVF-gel in the mixture formed by the small-granule fat suspension and the PRP is 10<6>-10<7> / ml, and the diameter of small-granule fat in the small-granulefat suspension is 0.18-0.425 mm. The diameter of the small-granule fat particles in the small-granule fat suspension is 0.18-0.425 mm, a double-layer cell sieve is adopted, compared with a traditionalcentrifugal separation method, the operation steps are reduced, and the treatment time of in vitro fat can be effectively reduced.
Description
technical field [0001] The invention belongs to the field of autologous fat transplantation, and in particular relates to a small particle fat filler for face lifting, a preparation method and a device. Background technique [0002] Facial aging is the change of skin, deep soft tissue and bone caused by multiple factors, leading to a series of aging manifestations on the face. With the growth of age and photoaging, static wrinkles gradually appear, and the wrinkles continue to increase and deepen. The skin gradually loses its elasticity, becomes rough, and spots appear, showing an old appearance. Due to the action of gravity, the supporting and lifting effect of the deep soft tissue is weakened, the volume is lost, and the sagging is loose. Skin aging is a long and complicated process. With age, under the action of internal and external factors, human skin undergoes degenerative changes. The obvious features are skin sagging and wrinkles, and the skin texture on exposed par...
