Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to invariable low negative pressure autologous fat liposuction ware.
Background
Since the 70's of the last century, autologous fat transplantation has become a method of confirmation in the orthopedic world and is gradually applied to various fields of cosmetic surgery. For example, it can be used for filling subcutaneous sunken defect or malformation of face, congenital breast dysplasia, breast atrophy after lactation, and bilateral breast size asymmetry. When the liposuction molding is carried out, the autologous depression can be filled, and compared with non-autologous filling materials such as a silica gel prosthesis, the self-autologous depression filling material has the advantage of no immunological rejection. At present, two ways are mainly adopted for obtaining fat, one way is to obtain fat by using a negative pressure liposuction machine, and the other way is to manually suck fat by using a syringe at low negative pressure. Research shows that the adipose tissue obtained by low negative pressure liposuction has better biological activity, and has better preservation rate after transplantation compared with the adipose obtained by high negative pressure liposuction of a negative pressure liposuction machine. However, the manual liposuction with low negative pressure by the injector is difficult to obtain more fat in a short time, and the operation time is long; in addition, the adipose tissues are inevitably contacted with air during liposuction, so that the risk of fat pollution is increased; meanwhile, the manual control of low negative pressure is difficult to ensure the pressure stability, so the uniformity of the obtained fat is poor. On the other hand, the prior acquisition means also needs to transfer the fat to be transplanted into the injector for a plurality of times when the large-volume fat transplantation is carried out, thereby prolonging the operation time, reducing the operation continuity and increasing the infection risk.
