Multifunctional autologous fat transplantation device maintaining fat cell activity for short period

Abstract

The invention provides a multifunctional autologous fat transplantation device maintaining fat cell activity for a short period. The device comprises a needle guard, a syringe needle, and an injector body. The injector body comprises a needle cylinder and a plunger. The front end of the needle cylinder is provided with a needle tubing connected with the syringe needle. The needle cylinder is provided with scales. The needle cylinder is internally provided with a filter screen fixed on the inner wall of the needle cylinder. The needle cylinder is provided with a cell culture fluid storage tank. The cell culture fluid storage tank is internally provided with a fat cell culture fluid. The cell culture fluid storage tank and the needle cylinder are connected through a first solenoid valve. The invention provides the multifunctional device which integrates fat cell extraction, analysis, and injection, and the device provides stable environment which maintains fat cell activity for a short period. One-time extraction of fat cells and low-intensity and high-frequency injection can be performed, and steps of repeated extraction are reduced, and effect of low-intensity and high-frequency injection is improved.

Description

technical field [0001] The invention belongs to the field of surgical instruments, in particular to a multifunctional autologous fat transplantation device for short-term maintenance of fat cell activity. Background technique [0002] Autologous fat transplantation refers to sucking out the fat from the fat-rich parts of the body, such as the abdomen, buttocks, thighs or upper arms, etc., with negative pressure liposuction. After special treatment or pure fat particles, injection and implantation are required. A surgical method that changes the shape of the perfect recipient area by changing the defective recipient area. At present, more breast augmentation is done with autologous fat, in which excess fat cells from the body are transplanted and injected into the breast. Autologous fat transplantation is its own fat particles, and it will not produce immune reaction and rejection reaction. Autologous fat transplantation will not cause changes in the endocrine environment of...

Problems solved by technology

The problem is that it needs to be implemented in a strictly sterile environment, and it is easy to contaminate external microorganisms

CN103598901A discloses a fat transplantation device, which includes a filter screen, a fat extraction tube and a fat injection tube. After the fat is extracted, it is filtered through the filter screen, and the extraction, filtration and fat implantation of fat are realized in the same device, which avoids the process of fat transfer. Causes the problem of external pollution. The existing problems are that the filtration step can only be carried out by the weight of the fat cells, the filtration efficiency is low, and some broken fat cells cannot be effectively filtered out. At the same time, the filtration speed is slow, which affects the subsequent injection steps. The obtained fat cells cannot be preserved, and all of them need to be injected into the site to be transplanted immediately

In practice, it has been found that when injecting fat cells in transplantation, the fat cells can be shaped better in a small number of times, and the existing devices cannot meet the actual needs.
