Description

Technical Field

[0001] The present invention relates to the technical field of fat transplantation, and particularly to a cryogenic collection device for granular fat used in fat transplantation. Background Art

[0002] Fat transfer is to extract fat from one part of the body and inject it into another part after processing. During the fat transfer process, fat granule collection is one of the important steps in fat extraction; fat is aspirated from a fatty area through a negative pressure liposuction method; the aspirated fat is centrifuged and purified to separate pure fat granules; these fat granules will be used in subsequent fat transplantation surgeries. The cryogenic collection technology can help maintain the quality and function of fat, thus playing an important role in fat transplantation. After the collected fat granules are cryopreserved in an incubator, the fat granules are usually placed in a carrier box or a test tube. In some cases, the inside of the carrier container is not completely filled with fat granules, and there is generally a certain amount of empty space. If the air in this area contains bacteria or other substances, it will have a certain impact on the fat granules. Moreover, different types of fat granules at different times are placed in the incubator together, and frequent opening and taking will also have a certain impact on the temperature and sterile environment inside the incubator.
