It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Examples
Fig. 1 is a schematic structural diagram of a processing apparatus according to an embodiment of the present invention. As shown in fig. 1, a processing apparatus provided in an embodiment of the present invention includes: a process chamber 110, a first extrusion block 120, a second extrusion block 130, and a first cutting web 140. A first extrusion block 120 disposed at a first end 1101 of the process chamber 110; a second extrusion block 130 disposed at a second end 1102 of the process chamber 110 opposite the first end 1101; a first cutting mesh 140 disposed inside the process chamber 110 adjacent to the first pressing block 120; wherein the first extrusion block 120, the processing chamber 110 and the second extrusion block 130 form a sealed processing chamber; the first extrusion block 120 and the second extrusion block 130 are respectively movably connected with the processing cavity 110; the first cutting mesh 140 includes a plurality of cutting grids.
Wherein the processing chamber 110 is a sealed chamber. The shape of the processing chamber 110 may be cylindrical, rectangular parallelepiped, etc., and the user may set the shape of the processing chamber 110 according to actual requirements. In the present embodiment, the processing chamber 110 is described as a cylinder, see fig. 1.
In this embodiment, the two bottom surfaces of the process chamber may be referred to as the first end 1101 and the second end 1102 of the process chamber 110. That is, the first end 1101 of the processing chamber 110 is one end of a cylindrical floor; the second end 1102 may be the other end of the cylindrical bottom surface, i.e., the first end and the second end are opposite.
In this embodiment, one end of the process chamber into which the material is injected may be referred to as a first end, and one end of the process chamber from which the material is output may be referred to as a second end.
With continued reference to fig. 1, the first extrusion block 120 is disposed at a first end 1101 of the process chamber 110 and the second extrusion block 130 may be disposed at a second end 1102 of the process chamber 110, although it is also possible that the first extrusion block 120 is disposed at the second end 1102 of the process chamber 120 and the second extrusion block 130 is disposed at the first end 1101 of the process chamber 110. Since the first extrusion block 120 and the second extrusion block 130 are the same in size and material, it is not limited to which extrusion block is disposed at which position, and it is only necessary to ensure that the first extrusion block 120 and the second extrusion block 130 are disposed at the first end 1101 and the second end 1102 of the processing chamber 110, respectively, so that the processing chamber 110 can form a sealed processing chamber. Wherein the first extrusion block 120 and the second extrusion block 130 are movable within the processing chamber 110, i.e., movably connected to the processing chamber 110.
With continued reference to fig. 1, the first expression nub 120 and the second expression nub 130, where the cross-sectional area of the end proximate the processing chamber 110 is the same as the bottom area of the processing chamber 110, can be 2cm, 3cm, etc. in thickness. The end of the extrusion block adjacent the processing chamber 110 may be formed of a rubber material or may be formed of a rigid material followed by a rubber material. This has the advantage that the tightness of the treatment chamber can be increased. Handles 1201 are provided on the first and second squeezing blocks 120, 130 at the ends remote from the treatment chamber. The user may control the squeezing blocks via the handle 1201 to cause relative displacement within the treatment chamber 110.
It should be noted that, when the first extrusion block 120 and the second extrusion block 130 are not disposed in the process chamber 110, the process chamber 110 has a hollow cylindrical shape without upper and lower bottom surfaces.
With continued reference to fig. 1, the first end of the processing chamber 110 is also fixedly disposed with a first cutting mesh 140. The first cutting wire 140 is adjacent to the first expression nub 120. The first cutting screen 140 may be cylindrical, have a cross-sectional dimension equal to the dimension of the bottom surface of the process chamber 110, and may have a thickness of between 1.5 μm and 2 μm, and optionally, 2 μm. The material used may be a rigid material. The advantage of using a rigid material is that it can withstand a certain impact force. The first cutting mesh 140 includes a plurality of cutting meshes, each having a sharpness, for cutting the substance injected into the treatment cavity 110, and optionally, the substance injected into the treatment cavity 110 may be fat. The shape of each cutting mesh of the plurality of cutting meshes may be quadrilateral, hexagonal, etc. The aperture user of each cutting grid can set according to actual needs, and optionally, the aperture of the cutting grid is 1200 meshes.
Referring to fig. 1, when the user moves the first pressing block 120 toward the first cutting mesh 140 by pushing the handle 1201, since the first cutting mesh 140 is made of a rigid material and has a certain sharpness, the adipose tissues may be cut through at least one cutting mesh to obtain a substance, optionally, fat micro-segments, desired by the user. As the first expression nub 120 moves toward the sealed process chamber 110, the second expression nub 130 may move away from the process chamber 110. That is, the first and second pressing blocks 120 and 130 are required to be movably disposed in the processing chamber. The first cutting screen 140 is fixedly disposed at the first end 1101 of the processing chamber 110 and adjacent to the first extrusion block 120. The at least one cutting grid may cut material within the treatment cavity as the first expression nub 120 is urged to move.
In order to obtain the substances required by the user, the processing device can be further provided with: a second cutting net is fixedly arranged at the second end of the treatment cavity, i.e. the fat micro-segment outlet end, and is adjacent to the second expression block, see fig. 2. The second cutting net 150 is made of the same material and has the same size as the first cutting net 140, except that: the pore size of at least one cutting mesh in the first cutting mesh 140 is larger than the pore size of at least one cutting mesh in the second cutting mesh 150. Optionally, at least one cutting mesh in the first cutting mesh 140 has a pore size of 300 meshes, and at least one cutting mesh in the second cutting mesh 150 has a pore size of 1200 meshes.
In order to further ensure that the substance output by the output interface is the substance desired by the user, a third cutting mesh 160 is also provided between the first cutting mesh 140 and the second cutting mesh 150, see fig. 3, and fig. 4 is a partial sectional view of fig. 3. Wherein the third cutting net 160 also includes a plurality of cutting grids. The aperture of at least one cutting mesh in the third cutting mesh 160 is larger than the aperture of at least one cutting mesh in the second cutting mesh 150.
Referring to fig. 3 and 4, a third cutting screen 160 is fixedly disposed in the processing chamber between the first cutting screen 140 and the second cutting screen 150. The third cutting net 160 is also made of a rigid material and includes at least one cutting mesh, so that the cutting process can be performed on the substance in the processing chamber 110. Accordingly, the aperture of at least one cutting mesh in the third cutting mesh 160 is smaller than the aperture of at least one cutting mesh in the first cutting mesh 140, so that the material cut by the first cutting mesh 140 can be cut again.
Referring to any schematic diagram in fig. 1-3, on the basis of the above technical solution, at least one input interface 1103 is disposed at the first end 1101 of the processing chamber 110, and at least one output interface 1104 is disposed at the second end 1102 of the processing chamber 110, where the input interface 1103 may also be a three-phase interface.
The number of the at least one input interface 1103 may be one, two, or more. If the input port 1103 is a three-phase port, one end of the port is connected to the treatment chamber 110, and the other end is used for injecting other substances, optionally, one port is used for injecting the extracted adipose tissue, and the other port is used for injecting the physiological saline. If there are a plurality of input ports 1103, they may be disposed at any position of the first end of the treatment chamber, and each port is used for injecting saline and adipose tissue, respectively. The number of the output interfaces 1104 may also be plural, and optionally, one. The output interface 1104 can output the processed material from the processing device, and can also output other impurities.
For example, adipose tissue and saline may be injected simultaneously at different input interfaces 1103. The saline can flush out impurities in the adipose tissue that are not needed by the user, and the impurities flow out from the output interface 1104 until the saline output from the output interface 1104 is clear, so that the adipose tissue in the treatment cavity 110 is determined to be needed by the user. After the adipose tissue in the treatment cavity 110 is again treated, it can be output from the output interface 1104. During the process of treating the adipose tissues, the output interface 1104 and the input interface 1103 are not communicated with the outside.
With further reference to fig. 3, the first expression nub 120 and the second expression nub 130 can be relatively displaced within the processing chamber 110. In order to avoid that the maximum displacement of the first extrusion block 120 is lower than the input port 1103 and the maximum displacement of the second extrusion block 130 is higher than the displacement of the output port 1104 when the extrusion blocks are moving in the process chamber 110, the input port 1103 may be arranged between the first extrusion block 120 at the maximum displacement relative to the first cutting wire 140 and the first cutting wire 140, and correspondingly the output port 1104 is arranged between the second extrusion block 130 at the maximum displacement relative to the second cutting wire 150 and the cutting wire.
In order to improve the convenience of the user in adjusting the positions of the first squeezing block 120 and the second squeezing block 130 in the treatment chamber 110, a handle 1201 may be provided at each end of the first squeezing block 120 and the second squeezing block 130 facing away from the treatment chamber 110. The user can control the position of the first expression nub 120 and the second expression nub 130 within the treatment chamber 110 via a handle 1201, see fig. 1-3.
To further enhance the convenience of using the squeezing blocks, a rigid material may be used to connect the handles 1201 provided at the ends of the first squeezing block 120 and the second squeezing block 130 facing away from the treatment chamber 110, respectively, as the hand-held portions 1202. The user can move the first pressing block 120 and the second pressing block 130 movably disposed in the processing chamber 110 toward one direction by shaking the hand-held portion 1202, so that the material in the processing chamber 110 is cut and filtered through the first cutting net 140, the second cutting net 150, and the third cutting net 160, respectively, to obtain the target material desired by the user.
On the basis of the above technical solution, in order to avoid the situation that the first pressing block 120 and the second pressing block 130 are separated from the processing chamber 110 when the user shakes the handheld portion 1202, a limiting member is respectively disposed at the first end and the second end of the processing chamber 110.
The limiting piece is used for ensuring that the first extrusion block and the second extrusion block move in the processing cavity. The limiting part can be a clip, a leather sheath or a clamping part carried by the first end of the processing cavity. In particular, a small protrusion may be provided at each of the first and second ends of the chamber, and when the first and second squeezing blocks are moved to this position, no further relative displacement can occur. The leather sheath is detachably connected with the treatment cavity, and at least one grid is arranged on the leather sheath, so that the extrusion block is difficult to separate from the treatment cavity.
It should be noted that, no matter which limiting member is used, it is only necessary to ensure that the first squeezing block and the second squeezing block cannot be separated from the treatment cavity in the process of shaking the handheld portion and/or the handle, and the specific limiting member may not be limited.
Wherein, in order to avoid the in-process of handling the material in the sealed processing cavity, every cutting net takes place the breakage, has still set up the support frame for support each cutting net. Namely, each cutting net is provided with a supporting frame corresponding to the cutting net, so that the probability of breakage of each cutting net is reduced.
In this embodiment, the flow of processing the fat injected into the sealed processing chamber by using the processing device may be: the extracted fat is injected into the treatment cavity from the fat input interface, and the physiological saline is injected into the treatment cavity from the saline injection interface. The physiological saline flushes the fat injected into the processing cavity, removes blood residues and grease in the fat, and flows out from the impurity output interface at the second end of the impurity processing cavity. When the physiological saline flowing out from the impurity output interface is relatively clear, the impurities in the treatment cavity are completely removed, the output interface can be closed, and the physiological saline with preset amount is continuously injected from the input interface, namely, the adipose tissues and part of the physiological saline exist in the treatment cavity at the moment. The first extrusion block and the second extrusion block move in the treatment cavity through the shaking of the handheld part, so that the adipose tissues are cut through the first cutting filter screen, the second cutting filter screen and the third cutting filter screen. When the adipose tissues in the treatment cavity are light yellow transparent liquid with a compact structure, the adipose micro-fragments are obtained and then rotated by a preset angle, optionally 180 degrees, so that the adipose micro-fragments are positioned at an adipose micro-fragment output interface, the adipose tissue output interface is opened, and the adipose tissues are introduced into the drainage tube from the output interface.
According to the technical scheme of the embodiment of the invention, a first extrusion block is arranged at a first end of a processing cavity, a second extrusion block is arranged at a second end opposite to the first end in the processing cavity, and a first cutting net is arranged in the processing cavity and adjacent to the first extrusion block, wherein the first extrusion block, the processing cavity and the second extrusion block form a sealed processing cavity; the first extrusion block and the second extrusion block are respectively movably connected with the processing cavity; the first cutting net comprises a plurality of cutting grids, the technical problems of uneven cutting and microbial pollution caused by manual participation when adipose tissue is cut in the prior art are solved, and the technical effect of efficiently and uniformly processing the adipose tissue in an aseptic environment is realized.
