[0004] There is also a type of incision skin muscle exposure after fracture modeling instruments and tools, which violates the basic facts of the actual fracture process and fracture healing principle. Dry fractures are caused by external forces. The displacement of fracture fragments and the damage to surrounding muscle and soft tissue at the moment of fracture are the initial conditions for the subsequent fracture healing hematoma environment. Modeling after incision and exposure violates the most basic fracture environment.

[0043] The animal leg fracture experimental model breaking device of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0046] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0048] like Figure 1-Figure 7 As shown, the animal leg fracture experimental model breaking device comprises: a supporting plate 1 for supporting, a breaking seat 2 for placing the animal leg, and a lower pressing frame 3 for pressing down the animal leg. The upper side of the support plate 1 is connected to the breaking seat 2, and one end of the support plate 1 is hinged to the lower pressing frame 3. A lower pressing plate 4 extends from the lower side of the lower pressing frame 3, and the lower pressing plate 4 is arranged on both sides of the breaking seat 2. The lower pressing frame 3 is rotated relative to the support plate 1 to change the distance between the lower pressing frame 3 and the support plate 1, and the breaking seat 2 is arranged at the distance so that the formation of the animal leg fracture experimental model can be smoothly realized. Specifically, for example, the thigh of a rat is placed on the upper side of the breaking seat 2, and the formation of the fracture experimental model of the rat thigh is smoothly realized through the downward pressure of both sides of the lower pressing frame 3.

[0049] Preferably, an anti-skid pad is fixedly connected to the bottom of the support plate 1 to ensure the stability between the entire breaking device and the experimental table during the experiment.

[0050] In order to facilitate the limiting effect of the soft tissue of the animal's leg and the limiting effect on the long bone shaft, it is ensured that the relative sliding distance is small during the fracture process, and the fracture position is ensured to be the position expected by the experimenter. The fracture seat 2 includes: a seat body 21 with a main supporting function, a soft tissue limiting groove 22 for limiting the relatively large soft tissue, and a long bone shaft limiting groove 23 for supporting the hard long bone shaft. The bottom of the seat body 21 is connected to the support plate 1 (adjustable connection, to meet the requirements of different sizes with one device), the long bone shaft limiting groove 23 is opened in the middle of the seat body 21, and the soft tissue limiting groove 22 is opened on the upper side of the long bone shaft limiting groove 23. The entire animal thigh is placed inside the soft tissue limiting groove 22, and the long bones of the thigh are supported by the small-sized long bone shaft limiting groove 23, so as to smoothly meet the formation of the animal leg fracture experimental model.

[0051] Of course, in order to ensure that the soft tissue is protected from support damage, the soft tissue limiting groove 22 and the long bone shaft limiting groove 23 have a smooth transition.

[0052] In order to prevent the soft tissue from sliding and failing to support the long bone shaft during the fracture process, the phenomenon of losing the soft tissue supporting the long bone shaft during the normal collision fracture process during the fracture process is lost, which leads to the loss of normal damage to the soft tissue and is out of practice. A lower anti-skid protrusion 24 is convexly arranged on the inner wall of the soft tissue limiting groove 22. Since the speed is generally fast during the normal collision process, the soft tissue is not easy to slide and dislocate with the long bone shaft, so the soft tissue will be greatly damaged during the collision process. Therefore, in order to restore the normal collision to the maximum extent in the experimental model, the lower anti-skid protrusion 24 is used to prevent the soft tissue from slipping, thereby ensuring that the damage to the soft tissue caused by the collision is restored during the fracture process and the accuracy of the model is ensured.

[0053] In order to meet the use requirements of different sizes of animal legs in a breaking device, and to properly adjust the position of a breaking seat 2 to ensure the breaking effect, an adjustment slot 11 is provided through the support plate 1, and the center line of the length direction of the adjustment slot 11 is within the plane where the lower pressing frame 3 is hinged and rotated; thus, the breaking seat 2 can be adjusted along the length direction of the adjustment slot 11 to meet the requirements of different animal thigh breaking experiments.

[0054] In order to further limit the position of the breaking seat 2, the direction of the long bone limit groove on the upper side of the breaking seat 2 can be ensured to be perpendicular to the lower pressing frame 3 to ensure the breaking effect. The upper surface of the adjustment notch 11 is provided with a limit groove 12 to ensure that the bottom of the breaking seat 2 is limited inside the limit groove 12.

[0055] In order to adjust the length direction of the slot 11 to meet the breaking test of animal legs of different sizes, a plurality of lower pressing openings 41 are provided on the lower side of the lower pressing plate 4. The lower pressing openings 41 meet different experimental requirements. The small size meets the small size of animal legs, and the large size meets the large size of animal legs.

[0056] Of course, in order to limit the position of the animal's legs and ensure the accuracy of the breaking position, each lower pressing opening 41 is in an arc-shaped structure, thereby limiting the animal's legs in the middle of the arc-shaped structure.

[0057] In order to facilitate the adjustment of the working position of the breaking seat 2, the requirements for the experimenter to select and judge the lower pressure port 41 are reduced. The size of the lower pressure port 41 increases from near the hinge to far away from the hinge. The large-sized animal legs are set backwards at one time, and the small-sized animal legs are close to the hinge for experiment.

[0058] Similarly, it is ensured that the soft tissue on the upper side of the fracture also slides relatively less during the fracture process, ensuring that the experiment restores the collision fracture. Each lower pressure port 41 is provided with an upper anti-slip convex point 42. It is ensured that the soft tissue damage is restored during the fracture process, thereby improving the internship requirements for medical staff.

[0059] In order to facilitate the operation of the pressing frame 3 and the experimenter's operation, the pressing frame 3 includes: a hinged plate 31 for the breaking test and a pressing handle 32 for the experimenter to hold and operate, one end of the hinged plate 31 is hinged to the support plate 1, and the other end of the hinged plate 31 is fixedly connected to the pressing handle 32; thus, the torque of the hinged plate 31 can be increased by the longer pressing handle 32, reducing the requirement for the downward force and the labor intensity of the experimenter.

[0060] In order to further facilitate the impact of the middle part of the soft tissue, there is enough sliding space, and it is convenient for the experimenter to run through the fracture process. An observation port 33 is opened through the hinge plate 31, and the animal leg fracture process can be conveniently observed through the observation port 33.

[0061] In order to facilitate observation of each pressing opening 41 during the breaking process, all pressing openings 41 are arranged below the observation port 33 .

[0062] The utility model is used to manufacture fracture sites with relatively consistent long bone shaft positions, and to a certain extent reduces unnecessary soft tissue trauma, while being able to restore the real damage to soft tissue during the collision process. It simplifies the structure and operation of existing devices, simulates the actual fracture environment, does not limit the impact displacement of fracture fragments after fracture, and simply and efficiently realizes the construction of fracture models. It simplifies the device and provides convenient operation, and the modeling device can be easily moved according to experimental needs. The production cost is low, and it is easy to promote and use.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
