Abstract
The present invention relates to a container, a device and a kit for preparing adipose tissue from aspirated fatty material, which can be used for injection. In particular, a washing and separating container for preparing adipose tissue has a washing chamber for washing aspirated fatty material, the container having an inlet and an outlet for the fatty material to enter the washing chamber through the inlet and for the fluid component of said material to leave said chamber through the outlet, said washing chamber comprising inside it at least one stirring assembly for mechanically forming an emulsion of the fluid component, each stirring assembly comprising an elastic member and at least one ball attached to the elastic member. Because the elastic component is fixedly connected with the ball body, slight vibration and shaking can also cause the small ball in the container to move to a larger extent, and the turning of the spring causes undifferentiated eddy current movement, thereby more effectively promoting the formation of emulsion, simplifying the operation process and improving the working efficiency.
Description
Technical Field
The present invention relates to a container, a device and a kit for preparing adipose tissue from aspirated fatty material, which can be used for injection.
Background
As early as the 70's of the last century, autologous fat transplantation has become a method of confirmation in the plastic surgery world, and has been gradually applied to various fields of cosmetic plastic surgery. Autologous fat transplantation requires treatment of the sucked fat, and it is important that red blood cells in the sucked fat and fatty oil components produced from the crushed fat cells must be discharged first. This is because the components after the decomposition of erythrocytes destroy normal tissues, thereby destroying adipocytes and reducing the survival rate of transplantation of fats; while fatty oil is separated from fat cells, it decomposes and forms acidic free fatty acids, which also become a factor for destroying normal tissues and normal fat cells to reduce the survival rate of fat transplantation, and the formation of free fatty acids also causes and increases cell death, which easily increases the probability of secondary infection or becomes a culture base of bacteria, and the fatty oil can remain on the wall and cells of fat cells, like blood membranes, to prevent the supply of oxygen necessary for the survival of transplanted fat cells, resulting in the necrosis of fat cells. For these reasons, it is generally necessary to remove the fatty oil before the fat transplantation, but it is still difficult to completely separate the fat due to the operation conditions and facilities, or a part of the fat is mixed into the transplanted fat, especially the fatty oil which is frequently accumulated in the lower part of the transplanted space when the transplanted amount is large, which may affect the operation effect, and the symptoms include causing inflammation or destroying tissues, forming a large lump, being touched like the lump, etc.
In order to remove erythrocytes and fatty oil from the extracted fat, the most original method is to naturally separate the extracted fat by standing the extracted fat in a funnel-shaped container, but the separation of fatty oil (the fat is separated and then located on the upper layer of the fat) is difficult and time-consuming in this method. Another original treatment method is to pack the extracted fat with cloth and then squeeze the fat with hands to separate impurities, and simultaneously compress the fat by the squeezing force to achieve the purpose of separating and filtering out the fat oil, but the method also takes a lot of time, is complicated in process, has a separation effect related to operators, and more importantly, has the risk of infection after the fat is contacted with hands of people and air.
In order to separate red blood cells and fatty oil safely and efficiently, some technical developments using a syringe-shaped container as a separation device and developments of related devices have been successively reported. The chinese patent application 200480002834.0 discloses a closed loop fat transplantation system, which can be seen from the description of the specification, and the transplantation system mainly aims at a large amount of fat transplantation operations to achieve the purpose that bacterial infection does not occur in the processes of fat extraction, liquid separation and fat transplantation, but the composition relationship among the components of the system is relatively complex, the operation requirement is relatively high, and the popularization and application are not facilitated, and the transplantation system does not consider the problem of fat oil separation. Chinese utility model patent 2006220113167 discloses an autologous fat transplantation adipocyte gathers screening syringe in x, sets up inside and outside piston in the syringe, forms negative pressure lacuna and accomplishes the liposuction through the liposuction machine in intraductal, later need take out this inside and outside piston, insert the former syringe push-and-pull rod that has the flap through special transformation, make the grease spill over through the flap through the centrifugation, then change the syringe push-and-pull rod again and accomplish the injection transplantation of fat. It can be seen that the separation of the fatty oil in the patent technology only depends on centrifugation, the spilled fatty oil is only located at the upper part of the fat and is difficult to separate completely, especially when only a small amount of fat tissue is separated, the accuracy is reduced, and only pure fat tissue can be lost to avoid the mixing of the fatty oil, so that the loss of the fat is caused.
Chinese patent application 201180034851.2 discloses an apparatus and method for preparing adipose tissue, the device structure is shown in figure 1, and comprises at least one washing and separating container 1, wherein the at least one washing and separating container 1 is provided with a washing chamber 101 for washing liposuction materials, the container 1 is provided with an inlet 102 and an outlet 103, for allowing lobular fatty material extracted by fat suction to enter the washing chamber 101 through the inlet 102 and for allowing fluid components in the material to leave the chamber 101 through the outlet 103, and said washing chamber 101 comprises means for forming an emulsion of the fluid components by mechanical agitation, the emulsion forming means being constituted by at least one agitation element 104, such as a ball or the like, for increasing the emulsification of said liquid components when said washing and separating vessel 1 is subjected to mechanical or manual agitation. When the device is used for the preparation of adipocytes, as shown in figure 2, it comprises at least four steps, one being a washing step, the container 1 is kept in vertical position with the outlet 103 facing the ground, repeated washing is carried out by pressure injection of a liquid material, such as sterile saline, into said inner washing chamber 101, to obtain a high-purity cell mass free from any oil, blood and any solution used during the extraction (figure 2 a); secondly, an emulsifying step, in which the container is oriented in a horizontal position, i.e. approximately parallel to the ground, said container 1 being stirred manually or mechanically to promote the emulsification of the fluid components, in particular the oil component with the sterile fluid substance and the blood (fig. 2 b); a third emulsion removal step, arranging the container 1 in a vertical position with respect to the floor with the outlet 103 facing downwards, to obtain stratification of the solid components, including the cell debris, the cells and the solid component of the one or more cell agglomerates floating on the emulsion of fluid components, on the liquid emulsion constituting the fat contained in the washing chamber 101, discharging the emulsion of fluid components (i.e. the oil/liquid) from the washing chamber 101 through the outlet 103 of the washing and separating container 1 (fig. 2 c); fourthly, the solid component removal step, such that the outlet 103 of the vessel 1 is oriented vertically upwards, such that the solid component floats on the wash solution (fig. 2d) to discharge the solid component from the wash and separation vessel.
The above-mentioned patent application of the invention promotes the production of the emulsion by arranging a plurality of beads as stirring means in the container, thereby improving the purity of the fat cells, however, since the beads have a certain mass and sink to the bottom when the container is placed vertically, in this case, they vibrate and shake, and the stirring action of the beads is very limited, it is necessary to perform the stirring operation after the container is moved laterally, i.e., the above-mentioned emulsification step, which increases the operation difficulty, and if it is a manual operation, the possibility of contamination is increased, and if it is a mechanical operation, the mechanical complexity is increased, because a rotation driving means for rotating the container from the vertical position to the horizontal position needs to be specially arranged. Meanwhile, in the whole adipose cell preparation process, at least three times of orientation conversion operations of the container are required, and because the two ends of the container are both connected with the pipelines, the stability of the connecting part of the pipelines and the container is inevitably affected under the condition of multiple orientation conversion operations, so that the pollution possibility is increased. In addition, even if the container is horizontally placed in the emulsification step, the small balls can still move more intensively at the position close to the ground in the shaking/stirring process due to the gravity of the small balls, and the stirring action is different in the whole container, so that the emulsification efficiency needs to be improved.
Therefore, in view of the above technical problems of the prior art, there is still a need for an apparatus and method for preparing adipocytes that can be more conveniently operated and more efficiently emulsified.
Disclosure of Invention
The object of the present invention is to provide a device for preparing adipose tissue for transplantation from aspirated fatty material, such as lobular fat, i.e. fatty material containing large clumps of cells, cells and cell debris, which avoids the above-mentioned drawbacks.
It is a further object of the present invention to relate to a method for preparing adipose tissue for transplantation using the device, which allows maintaining biological materials in a completely closed system and preparing adipose tissue with a higher degree of purification through relatively simple operation steps and a relatively high degree of emulsification.
It is a further object of the present invention to provide adipose tissue, in particular adipocytes, prepared by the above-described device and method. It contains less blood and oil, and thus can maintain better surgical effect after implantation.
The above object is achieved by a device comprising at least one washing and separating vessel having a washing chamber for washing sucked fatty material, the vessel having an inlet and an outlet for fatty material entering the washing chamber through the inlet and for fluid components of said material leaving said chamber through the outlet, at least one agitation assembly for mechanically forming an emulsion of the fluid components being comprised in said washing chamber, each agitation assembly comprising an elastic member and at least one ball attached to the elastic member.

Optionally, one end of the elastic component is fixedly connected with the sphere, and the other end of the elastic component is in a free shape or is fixedly connected with the sphere.
Preferably, the resilient member is a helical spring, a leaf spring and/or a resilient rod.
Preferably, the length of the elastic member at rest is equal to or greater than the radius of the cross section of the container.
Optionally, one ball is provided on each resilient member, the ball being located at an end of the resilient member.
Optionally, a plurality of spheres are disposed on each resilient member.
Preferably, the plurality of spheres is symmetrically arranged along the longitudinal axis of the resilient member.
Preferably, size reduction means are provided inside the washing chamber for cutting the fatty material to be treated into smaller sizes.

It is also an object of the present invention to obtain adipose tissue or adipocytes prepared by the washing and separating vessel for preparing adipose tissue as described above.
Compared with the prior art, the invention has the following advantages:
1. since the elastic member is fixedly connected to the ball, even when the container is in an upright state, slight shaking and shaking causes a large movement of the ball in the container, and the turning of the spring causes an undifferentiated swirling motion, thereby more effectively promoting emulsion formation. The elastic components can be arranged in a plurality of numbers and are uniformly distributed in the transverse direction and the longitudinal direction, so that the container does not need to be moved in the longitudinal direction to realize sufficient stirring, and the working efficiency is improved.
2, because the stirring effect is mainly completed by the spheres, the spheres are the main sources for generating impact and friction on tissues in the container, the integrity of the fat cells can be ensured to the maximum extent, and the damage rate of the fat cells is reduced.
3, sufficient stirring can be realized by simple movement of the container, so that the operation process can be simplified, and the pollution risk in manual operation is reduced, and the mechanical complexity in mechanical driving operation is reduced.
4. The presence of the elastic means, without the need to stir transversely to the container, allows to add one or more size reduction meshes in the longitudinal middle of the container, for example close to the inlet, i.e. upstream of the stirring element, thus making it possible to guarantee the degree and effect of size reduction of the material to be treated, further increasing the working efficiency.

< adipose tissue preparation device and kit >
Fig. 8 shows a schematic view of a fat preparation device kit comprising a washing and separating vessel according to an embodiment of the present invention. The kit allows the transfer of fatty material to take place in a closed system where the fatty material from the donor and the finally prepared fatty tissue are completely free from the external environment.
The kit comprises a washing and separating container 1 as described in the above embodiments, a syringe 7 for aspirating material from a patient, a syringe 12 for collecting/injecting processed biological material, a washing liquid container 10 (e.g. a bag containing saline), a container 11 for collecting waste material, which are connected or can be connected together by a 7 sterile tube, a multi-way valve, a luer connector.
In particular, the inlet 102 and/or the outlet 103 of the washing and separating vessel 1 can be connected to a three-way valve 9, such as a luer lock syringe 7 known in the art connected by a tube or duct 8 to the inlet 102 of the washing and separating vessel 1 equipped with the three-way valve 9, the syringe 7 performing the aspiration of the fatty material via a cannula provided with one or more holes on its surface.
The washing liquid bag 10 contains a liquid, such as physiological saline, which is used to evacuate air from the container 1, provide pressure to force the fatty material into and out of the chamber 101, and to repeatedly wash the fatty material before washing and separating the fatty material.
The syringe 12 is connected to an outlet 103 for collecting the prepared biological material mixed with the liquid, which is allowed to settle to obtain separation of the solid component from the residual liquid component. The material stored in the container 12 may be designed to be reprocessed in washing and separating the container 1 and/or size reducing container 2 prior to final storage and/or re-injection.
A container for collecting waste material, such as a bag 11, is connected to the outlet 103 via the three-way valve 9, and the emulsion is collected therein.
The washing and separating vessel 1 may be held by a holding means (not shown) and provide for the driving of the desired movement of the vessel 1, for example to provide for the rotation of the vessel 1 in a plane perpendicular to the ground to effect the inversion of the vessel from the outlet 103 towards the ground to the inlet 102 towards the ground, and also to provide for the oscillating driving of the vessel 1 up and down and/or side to side in a plane perpendicular to the ground. Alternatively, the holding means may also provide rotation of the container 1 about an axis perpendicular to the ground.
< procedure for adipose tissue preparation >
Fig. 9 shows a flowchart of a method for preparing adipose tissue using the fat preparation device according to the embodiment of the present invention.
Specifically, in step 501, the size reduction step, pressure is provided by gravity/injection via the liquid within the washing liquid container 10, so that the resulting lobular fat is sucked through the size reduction device at least once, thereby separating the cell pellet so that it is as large or smaller than a predetermined size and so that it has on average about the same size.
In step 502, i.e. the washing and separating step, the sanitizing washing solution is injected at least once into the washing chamber 101 of the washing and separating container 1, said washing and separating container 1 being agitated to promote, by means of the emulsion forming means, the emulsification of the fluid components, in particular of the oil components with the sanitizing fluid substance, obtaining a stratification of the solid components on the liquid emulsion, said stratification of the solid components comprising the solid components of the cell debris, the cells and the one or more cell agglomerates; clean washing solution is injected through the inlet 102 and the emulsion of fluid components is discharged from the washing chamber 101 through the outlet 103 of the washing and separating vessel 1 and the removal effect of the density gradient of the emulsion of fluid components. This washing and separation step is repeated until the discharged fluid component is free of any impurities such as oil and/or blood.
In step 503, the solid component discharging step, the washing and separating vessel 1 is vertically positioned with the outlet 103 facing upward to allow the solid component to float on the washing solution, and the washing solution is injected under pressure through the inlet 102 of the washing and separating vessel 1 to allow the solid component to be discharged from the outlet 103.
Wherein the washing solution injecting step, the emulsion discharging step and the stirring step for producing the emulsion are all performed with the container 1 arranged in a vertical position, with the outlet 103 facing downwards, i.e. towards the ground.
Alternatively, the stirring step for producing the emulsion is carried out with the container 1 arranged horizontally with respect to the ground.
The above-described process allows obtaining transplantable adipose tissue/adipocytes that can be directly injected into a patient or stored under appropriate conditions, with a simple, rapid and inexpensive process.
The above disclosed devices, kits and methods forming the subject of the present invention can obviously be used not only for the preparation of adipose tissue to be transplanted, but also for the preparation of any type of tissue/cell mass that needs to have a high level of purity for use.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
