[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] In the description of the present utility model, unless otherwise specified, "multiple" means two or more than two; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] like Figure 1-Figure 7As shown, a fat cutting filter provided by an embodiment of the utility model comprises a shell 1 and a primary filter screen 2 and a secondary filter screen 3 installed in the shell 1, a first tube 11 and a second tube 12 are installed on the shell 1, the first tube 11 corresponds to the primary filter screen 2, the second tube 12 corresponds to the secondary filter screen 3, the primary filter screen 2 comprises a first filter disc 21 installed in the shell 1, a plurality of first filter holes 22 evenly distributed are opened on the first filter disc 21 along its own radial direction, and the first filter disc 21 corresponds to the surface of the first tube 11 with evenly distributed first filter teeth 23 fixedly connected.

[0031] Preferably, the first filter teeth 23 are conical, and the distribution of the first filter teeth 23 and the first filter holes 22 is as follows: Figure 4 and Figure 5 shown.

[0032] Preferably, the first tube 11 and the second tube 12 are both Luer connectors.

[0033] Preferably, the first filter hole 22 corresponds to the end of the first tube 11 and is a bell mouth. Figure 5 As shown, the minimum diameter of the first filter hole 22 is 0.8 mm, that is, the diameter of the first filter hole 22 gradually increases from the bell mouth to the outside. The bell mouth is arranged to guide the fat particles into the corresponding first filter hole 22.

[0034] When the fat cutting filter is in use, first, the injection needle is connected to the second tube 12, and the syringe is connected to the first tube 11. Secondly, the extracted fat is added to the syringe, and the syringe is pushed to squeeze the fat into the filter. The fat enters the interior of the shell 1 through the first tube 11 and reaches the location of the primary filter 2. At this time, the first filter teeth 23 arranged on the surface of the first filter disc 21 can hook and pull large particles of fat, tear and cut the fat under the pressure provided by the syringe, and the torn and cut fat particles are squeezed and cut through the first filter hole 22 to keep the particle size at a diameter of 0.8 mm.

[0035] The fat cutting filter provided by the embodiment of the utility model can block large particles of fat by setting the first filter teeth 23 on the first filter disk 21, thereby preventing the large particles of fat from directly entering the first filter hole 22 and causing blockage of the first filter hole 22. When the fat is squeezed by the syringe, the large particles of fat can also be cut so that the fat particles can smoothly pass through the first filter hole 22.

[0036] In another embodiment of the present invention, the secondary filter screen 3 includes a second filter disc 31 , and a plurality of filter units are arranged on the second filter disc 31 .

[0037] Furthermore, the filter unit includes a second filter hole 32, which is trapezoidal and radially penetrates the second filter disc 31. Second filter teeth 33 are formed on the second filter disc 31 from each side of the second filter hole 32 to the center of the second filter hole 32, and the second filter teeth 33 are all isosceles triangles.

[0038] Furthermore, each second filter tooth 33 is bent toward the primary filter screen 2. Preferably, the bending angle of the second filter tooth 33 is 44°.

[0039] Specifically, Figure 6 and Figure 7 As shown, the secondary filter screen 3 has 6 groups of sharp second filter teeth 33 that are tilted upside down. The 6 groups of second filter teeth 33 together form a filter unit with a filter diameter of 0.5 mm. When the fat passes through the second filter teeth 33, the second filter teeth 33 will perform tearing and cutting actions in different directions, and finally filter the fat through the second filter holes 32 to cut the fat into emulsions with uniform particle size. With this arrangement, when the second filter teeth 33 are subjected to excessive force, they will move closer to the middle of the second filter holes 32, and the second filter holes 32 will not increase due to repeated use of the secondary filter screen 3. This not only strengthens the strength of the secondary filter screen 3, but also ensures that the aperture of the second filter holes 32 will not increase after the second filter teeth 33 are deformed.

[0040] In another embodiment of the present utility model, the housing 1 includes a first shell 13 and a second shell 14 that cooperate with each other, the first tube 11 is fixedly connected to the middle of the first shell 13, the second tube 12 is fixedly connected to the middle of the second shell 14, and the first shell 13 and the second shell 14 are detachably connected, such as by using bolts to fix the first shell 13 and the second shell 14 to facilitate disassembly of the first shell 13 and the second shell 14 to take out the primary filter 2 and the secondary filter 3 for cleaning.

[0041] Preferably, the first shell 13 and the second shell 14 are both disc-shaped, and a plurality of protrusions 131 are formed on the first shell 13 and the second shell 14 to protrude outward. The plurality of protrusions 131 are distributed in a circular array around the central axis of the first shell 13 or the second shell 14. The protrusions 131 are formed on the first shell 13 and the second shell 14 to facilitate the rotation of the fat cutting filter when connected to the syringe with less effort.

[0042] Furthermore, the inner wall of the second housing 14 protrudes toward the second filter disc 31 and is provided with a plurality of support blocks 141, each of which contacts a surface of the second filter disc 31 corresponding to the second tube 12, and the support blocks 141 support the area of ​​the second filter disc 31 close to the central axis, such as Figure 1 and Figure 2 As shown, the second filter disc 31 is prevented from being deformed due to excessive pressure near the center.

[0043] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
