Description
Technical Field
The invention relates to the technical field of beauty medicine and surgery, in particular to a full-closed system for autologous fat filling transplantation.
Background
Modern people have higher and higher demand for beautiful appearance, so that modern medicine is developed in the beauty industry, so that an autologous fat filling transplantation operation is generated, autologous fat is transferred to other parts, the risk caused by rejection is reduced, extracted fat can be injected into the required transplanted part of a human body again only by treatment, the survival rate of fat cells is over 70 percent by adopting the operation according to the incomplete statistics of the market, the operation is very popular and favored by consumers, and another report also points out a series of problems of the operation, in the existing fat suction and autologous fat transplantation processes of medical beauty treatment, the fat suction is generally completed by two parts of fat suction and fat filling, and the fat suction sucks the fat of a user by hand or machine under constant pressure and uses a storage tank or a syringe for storage, then, water and impurities in the fat are filtered by means of centrifugation and the like, an effective fat part is injected to a position required by a user, multiple container transfer of the fat and exposure of the fat to the air can occur in the whole process, the fat pollution is easily caused, the survival rate of the fat in the body of the user and even infection can be caused finally, the operation time can be prolonged by completing fat suction and filling through two steps, the physical strength of a doctor is greatly consumed, and the operation amount which can be completed every day is low.
In view of the above problems, doctors have studied various time-saving and labor-saving surgical methods and surgical devices, but this has serious consequences, and since some doctors do not have the standard manipulations, some serious consequences are caused, so that consumers are not trusting the technology more and more. Chinese utility model patent specification; CN201922079929.9 discloses a novel fat transplantation device for operation is filled to autologous fat, the device includes a barrel, the barrel is a seal structure that comprises upper cover, lower cover and several connecting cylinder that sets up between upper cover and lower cover, all install the screen cloth that can dismantle the connection between adjacent two-layer in upper cover, connecting cylinder and the lower cover, this screen cloth is installed in the barrel by helicitic texture, the sieve mesh aperture of the screen cloth in this barrel from top to bottom progressively diminishes in proper order. The utility model discloses simple structure, the screen cloth is multilayer detachable construction, easy dismounting, easy cleaning, it is high to use the flexibility, and can also be according to the in-service use needs, select the connecting cylinder of suitable quantity and the screen cloth of suitable sieve pore diameter, thereby realize the filtration of fat granule and the function of multi-stage screening, sieve the speed with higher speed through negative pressure device, need not repeated dismantlement and flowing back many times, reduce bacterial contamination's chance, can also avoid flowing back many times simultaneously can lead to increasing the chance that the fat runs off, the availability of fat has been increased.
However, this technique has significant drawbacks, one of which is: because the cylinder body is of a separated structure, the situation that the fat is polluted when the cylinder body is not in contact with the outside during disassembly and the fat in contact with the outside has a great influence on the survival rate of fat cells in the next operation is avoided; the second step is as follows: although the grading type screening structure can achieve the precision of required components, the waste situation is inevitably generated, the autologous fat comes from the body of the patient, and the huge waste is not allowed, so that the potential hazard is great for doctors and patients.
