Description
Technical Field
The invention relates to the field of medical equipment, in particular to a device for collecting, purifying and transplanting autologous fat.
Background
In the medical field, after the body fat is collected and purified, the body fat is injected and filled into the affected part of the body, and the body fat is subjected to subcutaneous injection and filling treatment, so that the body fat can take effect quickly and has good effect, and is widely applied to places such as treatment of subcutaneous concave defects or deformity, treatment of hand soft tissue atrophy (commonly called chicken feet), treatment of genital reshaping and shaping, breast enlarging treatment of female breasts, shaping treatment of buttocks and the like. The treatment time is divided into three steps, the first step: firstly, collecting fat at a part with more fat of a human body; and a second step of: separating and purifying the mixture of oil drops, fascia and blood in the collected fat; and a third step of: the purified effective fat particles are injected into the corresponding parts of the human body for treatment.
When the fat is collected in the prior art, one is to collect the fat by using a syringe, the operation mode has the defects of time and labor waste and less fat collection, and when the fat utilization rate of a person to be operated is low, the collected fat is more difficult to meet the operation requirement, the time of the whole operation is prolonged, and the fat is excessively long in vitro to cause low survival rate of fat cells, so that the operation effect is influenced. Secondly, continuous suction of fat of an operator is carried out by using a negative pressure fat suction machine, after a sufficient amount of fat is collected at one time, oil drops, fascia and blood in the collected fat mixture are purified and separated by using purifying equipment, the fat suction speed is high, but the defect that the fat mixture is always in a negative pressure state in the whole fat suction process, the greater the negative pressure is, the longer the negative pressure is, the greater the damage to fat cells is, the lower the survival rate of fat cells is caused, and the operation effect is affected is overcome; and after fat collection, a complicated procedure for subsequent purification treatment is required. Thirdly, the negative pressure fat suction machine with the negative pressure bottle is adopted to suck fat, after the negative pressure fat suction machine pumps the fat mixture into the negative pressure bottle, the negative pressure bottle purifies and separates oil drops and blood in the collected fat mixture, the problems that fat is in a negative pressure state for a long time and the survival rate of fat cells is low are solved, and finally, only the fat particles, invisible blood and fascia mixture after standing are finally obtained and further the subsequent treatment is needed.
In the prior art, when the collected fat mixture is subjected to purification treatment, blood water (comprising invisible blood water, which is close to the color of fat and cannot be visually distinguished, and blood water which can be separated under the condition of centrifugation or cotton pad adsorption) and oil drops in the fat mixture are removed through centrifugal treatment or cotton pad adsorption treatment of a centrifugal machine, and effective fat particles are obtained through the steps of firstly subpackaging the fat mixture into a centrifugal tube during centrifugal treatment, and then putting the centrifugal tube into the centrifugal machine for centrifugation to obtain the fat particles, so that the operation speed is low, the contact time of the fat mixture with air is too long, and the fat mixture is easy to be polluted and infected with germs; the cotton pad is used for adsorbing blood and oil drops in the fat mixture manually, so that the operation speed is low, and the fat mixture is in contact with air for too long, so that the fat mixture is easy to be polluted and infected with germs. Both of these methods have the disadvantage that fascia in the fat mixture cannot be removed effectively.
In the prior art, when the human body is injected subcutaneously, if fat particles injected by injection contain fascia which is not thoroughly separated, the injection pushing force is overlarge due to the blocking effect of the fascia, so that the fat cells in the injector are extruded and damaged; if the blood and water in the fat is not separated thoroughly, the blood water and oil drop in the fat particles are too high, and the effect of the operation is greatly reduced due to too few effective fat particles.
Disclosure of Invention
In order to overcome the defects existing in the prior art that the body fat is collected and purified and then injected subcutaneously, the invention provides a negative pressure fat suction machine with a negative pressure bottle in the prior art, which is used as fat suction equipment, visible blood and partial oil drops in the extracted fat are removed at the same time when the fat is sucked, a certain amount of rest fat mixture can be transferred into an adsorption bag with an adsorption cotton pad without negative pressure as soon as possible after standing, the fat is collected while being sucked into the adsorption bag without negative pressure, the reduction of the cell survival rate of the fat caused by the action of the negative pressure for a long time is prevented, the rest invisible blood and oil drops in the fat mixture entering the adsorption bag without negative pressure can be effectively sucked by the adsorption cotton pad arranged in the adsorption bag, after the process of sucking and collecting the fat is finished, effective fat particles and a small amount of fascia tissues are directly obtained in the adsorption bag, and the fascia in the adsorption bag can be effectively filtered after the subsequent injection, so that the fat cells can be quickly sucked, the survival rate of the fat cells is high after the action time of the negative pressure is reduced, the fat cells are filtered in the adsorption cotton pad without negative pressure, and the effect of the skin impurities can be satisfactorily collected after the fat particles are injected into the body, and the body can be purified after the body is transplanted.

When the fat particles are injected into the affected part of a fat taker, an operator pushes the piston of the injector 6 forward by hands through the operating handle of the injector 6, so that the fat particles in the syringe 6 move forward, the fat particles in the syringe 6 open holes from the circular seat 7-3 at the left upper end of the second three-way plastic tube, impact the circular silicone rubber sheet 7-7 in the groove 7-5 at the left upper side of the circular seat at the left upper end of the second three-way plastic tube 7-2 to move upwards, the lower side of the circular silicone rubber sheet 7-7 and the upper side end of the circular seat 7-3 at the left upper end of the second three-way plastic tube are pulled apart by a distance, and the fat particles enter subcutaneous tissues from the circular seat 7-3 at the left upper end of the third three-way plastic tube and the second needle head 7-1 of the three-way fat injection needle assembly; at the moment, the impact force generated by pushing the piston can enable the circular silicon rubber sheet 7-8 in the groove 7-6 at the upper part of the left side of the circular seat at the right end of the second three-way plastic pipe 7-2 to move rightwards, the right side of the circular silicon rubber sheet 7-8 is tightly combined with the left side end of the circular seat 7-4 at the right end of the second three-way plastic pipe, and fat particles in the syringe 6 are prevented from escaping during injection. The invention can fully remove blood water, oil drops and fascia impurities in the fat mixture, has quick fat taking time, short time of the action of the negative pressure on the fat cells and high survival rate, and can obtain satisfactory treatment effect after the fat particles are injected into the skin of a human body.
The present embodiment is a preferred embodiment of the present invention, and is not intended to limit the present invention, but any modification, equivalent replacement, improvement, etc. within the scope of the present invention should be included in the protection scope of the present invention.
