DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The utility model can also be implemented or applied through other different specific implementation methods. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it is necessary to understand that the terms "length", "up", "down", "front", "back", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying 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 invention.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] like Figure 1-11A bone tissue cutting device is shown, which includes a pressurizing part 1, a cutting part 2 and a cutting knife net 3; the cutting knife net 3 is arranged inside the cutting part 2, and the cutting part 2 and the cutting knife net 3 are detachably connected; the pressurizing part 1 includes a pressure rod 12, an extrusion structure 13 and a connecting rod 14; one end of the connecting rod 14 is slidably connected to the pressure rod 12, and the other end is rotatably connected to the extrusion structure 13; the end of the pressure rod 12 away from the pull rod is connected to the cutting part 2 through a hinge structure 15; the end of the extrusion structure 13 away from the connecting rod 14 is adapted to the cutting part 2.

[0033] The cutting part 2 includes a box body 21 and a bracket 22; the box body 21 is arranged inside the bracket 22; and a mounting position 211 adapted to the cutting blade net 3 is arranged inside the box body 21. The box body 21 and the cutting blade net 3 are detachably connected, so that the cutting blade net 3 is easy to replace.

[0034] The extrusion structure 13 includes a pressing plate 131, a first tooth plate 132 and a rotating bracket 13322; one side of the pressing plate 131 is fixedly connected to the first tooth plate 132, and the other end is fixedly connected to the rotating bracket 13322. The first tooth plate 132 is adapted to the box body 21. The rotating bracket 13322 is rotatably connected to the connecting rod 14; so that the first tooth plate 132 can be aligned with the box body 21, and as the pressing rod 12 is pressed down, the first tooth plate 132 and the box body 21 will not shake. If the first tooth plate 132 and the box body 21 shake during the pressing process, it will cause the bone tissue to shift, making the section uneven.

[0035] The first tooth plate 132 has a first groove inside that matches the cutting blade net 3 , so that the first tooth plate 132 can push the bone tissue to completely pass through the cutting blade net 3 , ensuring that the bone tissue can be completely cut.

[0036] When in use, the decalcified bone tissue is placed inside the box body 21, and then the pressing structure 13 is aligned with the box body 21 and the pressing rod 12 is pressed down. The lever principle is used to increase the pressure of the decalcified bone tissue on the cutting blade net 3, so that the cutting blade net 3 can cut the decalcified bone tissue into a predetermined size. In addition, during the cutting process, the decalcified bone tissue cannot move inside the box body 21, and the cross section of the slice is smooth and flat. During the cutting process, the operator does not need to come into close contact with the cutting blade net 3, which effectively avoids injuries to the operator.

[0037] During the cutting process, the decalcified bone tissue is stuck on the cutting blade net 3. As the extrusion structure 13 is continuously pressed downward, a cutting groove with the same shape as the cutting blade net 3 is generated on the decalcified bone tissue. The cutting groove clamps the cutting blade net 3, so that the decalcified bone tissue is firmly fixed on the cutting blade net 3.

[0038] like Figure 1-11 As shown, the side of the bracket 22 away from the box body 21 is connected to the pressurizing part 1 through a hinge structure 15 .

[0039] Although this embodiment only provides a solution in which the box body 21 is arranged on one side of the bracket 22, and in combination with the accompanying drawings, it can be seen that the length of the pressure rod 12 is greater than the distance between the box body 21 and the hinge structure 15. Based on this embodiment, those skilled in the art can deduce that the box body 21 is located at any position inside the bracket 22 to keep the length of the pressure rod 12 greater than the distance between the box body 21 and the hinge structure 15, which still does not deviate from the spirit and scope of the present utility model.

[0040] Furthermore, the cutting part 2 further includes a reset structure 23 and a receiving structure 24; the receiving structure 24 is arranged inside the box body 21; and the reset structure 23 is arranged between the receiving structure 24 and the inner wall of the box body 21. When the extrusion structure 13 is pressed down, the decalcified bone tissue is located between the extrusion structure 13 and the receiving structure 24, and the receiving structure 24 moves toward the inside of the box body 21 and squeezes the reset structure 23 until the decalcified bone tissue is completely cut, the extrusion structure 13 rises upward, and the reset structure 23 restores its original shape, pushing the receiving structure 24 out of the box body 21, thereby pushing the cut bone tissue to rise, making it easy to take out the cut bone tissue from the box body 21.

[0041] Specifically, the reset structure 23 is a linear compression spring. In order to ensure that the receiving structure 24 can be raised smoothly, multiple reset structures 23 are provided, and the multiple reset structures 23 are evenly arrayed inside the box body 21.

[0042] like Figure 1-11 As shown, the receiving structure 24 includes a second tooth plate 241 and a bottom plate 242, and the second tooth plate 241 is fixedly connected to the bottom plate 242; the second tooth plate 241 is arranged on a side of the bottom plate 242 away from the reset structure 23; the second tooth plate 241 is provided with a second groove adapted to the cutting blade net 3. When the receiving structure 24 is raised, the second tooth plate 241 passes through the gap of the cutting blade net 3, and props up the cut bone tissue until it no longer contacts the cutting blade net 3, so as to facilitate the removal of the cut bone tissue from the box body 21, and prevent the operator's hand from touching the cutting blade net 3 and causing cuts.

[0043] like Figure 9-11 As shown, the cutting blade net 3 includes a first blade 31 and a second blade 32; a plurality of first blades 31 and a plurality of second blades 32 intersect each other to form a plurality of squares of the same shape, so that the bone tissue can be cut into sample blocks of the same shape.

[0044] The first blade 31 is provided with a first mounting groove 311, which is matched with the second blade 32. The second blade 32 is provided with a second mounting groove 321, which is matched with the first blade 31. The first mounting groove 311 is matched with the second mounting groove 321.

[0045] Specifically, the first mounting groove 311 is disposed at the sharp end of the first blade 31 ; and the second mounting groove 321 is disposed at a side of the second blade 32 away from the sharp end.

[0046] Alternatively, the first mounting groove 311 is disposed on a side of the first blade 31 away from the sharp end; and the second mounting groove 321 is disposed at the sharp end of the second blade 32 .

[0047] The method of using this embodiment is as follows:

[0048] 1. Place the decalcified bone tissue on top of the cutting mesh 3;

[0049] 2. Align the extrusion structure 13 with the box body 21 and then press down the pressure rod 12;

[0050] 3. After the bone tissue is completely cut, the pressing rod 12 is lifted to drive the extrusion structure 13 to exit the box body 21;

[0051] 4. The receiving structure 24 rises under the push of the resetting structure 23, driving the cut bone tissue to rise;

[0052] 5. Take out the cut bone tissue from the box body 21.

[0053] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0054] The embodiments described in this application are only part of the embodiments of the utility model, not all of the embodiments.
