Autologous fat collecting, cleaning and transplanting device

Abstract

The invention provides an autologous fat collecting, cleaning and transplanting device. Extraction and adsorption equipment is composed of a double-layer injector, a three-way liposuction needle assembly, an adsorption bag, a first connection hose and a negative pressure connecting pipe, an openings are formed in the surface of an inner needle cylinder body of the double-layer injector, and the three-way liposuction needle assembly comprises a first needle head and a first three-way plastic pipe. A liquid outlet end of a needle cylinder is sleeved with the first three-way plastic pipe, one end of the first connection hose is inserted into the first three-way plastic pipe, and the other end of the first connection hose is inserted into a liquid inlet pipe of the adsorption bag. One end of the negative pressure connecting pipe is inserted into a negative-pressure liposuction machine, and the other end of the negative pressure connecting pipe is inserted into a liquid outlet pipe on the left lower part of the needle cylinder. Filtration and injection equipment is composed of an injector, a three-way fat injecting needle assembly, a second connection hose and a filter, and the three-way fat injecting needle assembly comprises a second needle head and a second three-way plastic pipe. The liquid outlet end of a needle cylinder of the injector is sleeved with the lower end of the second three-way plastic pipe, one end of the second connection hose is inserted into the right end of the second three-way plastic pipe, and the other end of the second connection hose is inserted into a liquid outlet pipe of the filter. By means of the autologous fat collecting, cleaning and transplanting device, convenience is brought to liposuction, cleaning and injection.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a device for collecting, purifying and transplanting autologous fat. Background technique [0002] In the medical field, the body’s own fat is collected and purified, and then the subcutaneous injection of the affected part is performed for filling treatment. Due to the quick effect and good effect, it is widely used in the treatment of subcutaneous depression defects or deformities, soft tissue atrophy of the hand ( Commonly known as chicken feet), treatment for genital reshaping, breast enhancement treatment for female breasts, buttocks shaping treatment, etc. The treatment is divided into three steps. The first step: first collect fat from the body's own fat; the second step: separate and purify the oil droplets, fascia, and blood-water mixture in the collected fat; the third step: put After purification, the effective fat particles are injected into the corresponding parts o...

AI Technical Summary

Problems solved by technology

[0003] When collecting fat in the existing technology, one is to use a syringe for collection. This operation method has the disadvantages of time-consuming, laborious, and less fat collection. The amount of fat is more difficult to meet the needs of the operation, and it will also prolong the entire operation time. The long time of fat in vitro will cause the survival rate of fat cells to be low, which will affect the effect of the operation.

The second is to use a negative pressure liposuction machine to continuously aspirate the fat of the operator. After a sufficient amount of fat is collected at one time, the oil droplets, fascia, and blood in the fat mixture after collection are then treated with purification equipment. Purification and separation, this method of suctioning fat is fast, but the fat mixture is always in a state of negative pressure throughout the liposuction process, the greater the negative pressure and the longer the negative pressure action time, the greater the damage to the fat cells , resulting in a low survival rate of fat cells, which affects the surgical effect; and there are also cumbersome procedures that require subsequent purification after fat collection

The third is to use a negative pressure fat suction machine with a negative pressure bottle inside to carry out fat suction operations. After the negative pressure fat suction machine sucks the fat mixture into the negative pressure bottle, the negative pressure bottle will collect the oil in the fat mixture. Purification and separation of drops and blood water, this method also does not solve the problem of fat being in a negative pressure state for a long time and the survival rate of fat cells is low, and what is finally obtained is only fat particles after standing still, invisible blood water, fascia mixture, Still need to follow up

[0004] In the current technology, when the fat mixture is purified after collection, the blood water (including invisible blood water) in the fat mixture is removed through centrifuge treatment or cotton pad adsorption treatment, and the invisible blood water refers to the color close to the fat. , cannot be distinguished visually, blood and water that can only be separated under centrifugation or cotton pad adsorption conditions) and oil droplets to obtain effective fat particles, the centrifuge needs to first divide the fat mixture into centrifuge tubes, and then put the centrifuge tubes Centrifuge into the centrifuge to obtain fat particles, which leads to slow operation speed, and the fat mixture is in contact with the air for too long, which is easy to be polluted and infected with germs; and using cotton pads to absorb blood and oil droplets in the fat mixture also has operations The speed is slow, the fat mixture is in contact with the air for too long, and it is easy to be polluted and infected with germs.

And both methods have the disadvantage of not being able to effectively remove the inner fascia of the fat mixture

[0005] In the current technology, when the human body is filled with subcutaneous injection, if the injected fat particles contain incompletely separated fascia, due to the blocking effect of the fascia, the injection force will be too large, which will squeeze the fat cells in the syringe. If the blood-water separation in the fat is not complete, the effect of the operation will be greatly reduced due to the high amount of blood water and oil droplets contained in the fat particles, and too few effective fat particles for injection.
