Description

Technical Field

[0001] The invention relates to the technical field of fracture model experimental preparation, in particular to a fracture model preparation device and a fracture model preparation method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Due to different stress mechanisms, fractures will produce different morphologies. According to the type of fracture line, they can be divided into transverse fractures, short oblique fractures, spiral fractures, comminuted fractures, etc. Good fracture classification can assess the severity of the patient's related injuries and guide doctors in choosing subsequent treatment plans. However, in the process of clinical fracture experiments, it is difficult for us to generate the required fracture types, and we can only rely on three-point bending to prepare fracture models. For example, the animal fracture model making equipment disclosed in Chinese patent CN201810780220.9 realizes the preparation of fracture models by moving the longitudinal gate downward, which has the following shortcomings:

[0004] The fracture models prepared were mostly transverse fractures or short oblique fracture models, and spiral fracture models could not be formed;

[0005] The existing preparation device is only for model bones, because the model bones only need to be placed on the platform, because the object cannot be stably clamped and fixed. If the object shakes during the falling process of the knife body, the molding effect will be affected;

[0006] Moreover, when bones are covered by skin and soft tissue, it is impossible to effectively simulate the stress mechanism of fracture, so they are often cut or prefabricated with fracture lines, which affects the molding quality of the model.

[0007] The types of models produced by the equipment are relatively single, and the integration of the preparation of multiple fracture models is not achieved. Summary of the invention

[0008] In view of the shortcomings of the prior art, the object of the present invention is to provide a fracture model manufacturing device with reasonable structure and capable of manufacturing a spiral fracture model.

[0009] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0010] A fracture model production device includes a base, which supports a clamping assembly. The clamping assembly includes a support ring installed on the base, a clamping seat is connected to one side of the support ring, the clamping seat is communicated with the support ring, and the clamping seat can rotate relative to the support ring. The clamping seat is a hollow part for the passage of an object to be fractured. The clamping assembly is provided with at least two locations, and the clamping seat is circumferentially provided with openings. Fasteners pass through the openings to fix the object to be fractured. When the clamping seat rotates relative to the support ring, the object to be fractured is driven to rotate, thereby realizing the production of a spiral fracture model.

[0011] The fracture model making device as described above also includes a clamping gasket, which is arranged between the object to be fractured and the inner wall of the clamping seat. The fastener abuts against the clamping gasket after passing through the opening. The diameter of the clamping gasket is smaller than the inner diameter of the clamping seat, and the opening is a threaded hole, thereby ensuring stable fixation of the object to be fractured.

[0012] In the above-mentioned fracture model manufacturing device, the clamping gasket is formed by cutting a cylindrical member, and the cylindrical member is beveled from the end surface of the cylindrical member to form a plurality of clamping gaskets, and the plurality of clamping gaskets are placed in the circumferential direction of the object to be fractured;

[0013] The fastener is a bolt.

[0014] A fracture model making device as described above, wherein an extension frame is arranged on one side of the base, the extension frame is vertically or obliquely connected to the base, the extension frame is movably connected to the action rod, a first knife body is arranged on the side of the action rod facing the base, and when the action rod moves toward the base, the first knife body acts on the object to be fractured to achieve the making of a comminuted fracture model;

[0015] A counterweight rod is arranged on one side of the action rod relative to the first blade body, and the counterweight block can be sleeved on the counterweight rod.

[0016] In the above-mentioned device for making a fracture model, a pad can be arranged inside the base, and the pad is placed below the object to be fractured to support the object to be fractured from below to form a force fulcrum.

[0017] In the above-mentioned device for making a fracture model, the support ring can move along the length direction of the base to adjust the distance between two adjacent clamping assemblies to be suitable for objects to be fractured of different sizes;

[0018] The base comprises a frame-shaped body, rod bodies are respectively arranged on both sides of the base in the length direction, a sliding block is arranged at the bottom of the support ring, and the sliding block can be slidably installed on the rod body.

[0019] A fracture model making device as described above, wherein a lifting mechanism is arranged in the hollow of the base, a second knife body is arranged on the top of the lifting mechanism, a plane where the second knife body is located is parallel to the width direction of the base or is arranged at a set angle to the width direction of the base, and the second knife body gradually applies a force to the object to be fractured during the lifting process to achieve the making of a transverse or wedge-shaped fracture model;

[0020] When the second knife body contacts the bone at a tangent or a fulcrum, a transverse or short oblique fracture model will be formed. When the second knife body contacts the bone at a section or a curved surface, a wedge-shaped, transverse or multi-segment fracture model will be formed. The second knife body and the clamping seat work together to achieve the production of a short oblique or long oblique fracture model of the object to be fractured.

[0021] In the above-mentioned device for making a fracture model, the clamping seat is connected to the operating rod;

[0022] The support ring supports the clamping seat via a bearing.

[0023] In the fracture model making device as described above, the clamping assembly is provided at two locations, the two clamping assemblies are relatively arranged at the base, and the distance between the support rings in the two clamping assemblies is smaller than the distance between the clamping seats.

[0024] In a second aspect, the present invention further provides a method for making an animal fracture model, and the working method of the fracture model making device includes the following contents:

[0025] The fractured object is passed through all the clamping components;

[0026] The fastener passes through the opening of the clamping seat to fix the object to be fractured;

[0027] The clamping seat of one of the clamping assemblies is rotated relative to the support ring, or the clamping seat is operated to make the clamping seats in two adjacent clamping assemblies move in opposite directions, so that a spiral fracture occurs in the object to be fractured, thereby forming a spiral fracture model;

[0028] Alternatively, the lifting mechanism drives the second blade body to rise toward the object to be fractured, and gradually applies force to the object to be fractured during the lifting process, so as to achieve the production of a transverse or wedge-shaped fracture model;

[0029] Alternatively, the second blade body applies a force toward the object to be fractured, and the clamping seat drives the object to be fractured to rotate under the action of the external force, so that a short oblique or long oblique fracture model of the object to be fractured is produced.

DETAILED DESCRIPTION

[0043] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0044] 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 invention. As used herein, unless otherwise explicitly stated in the present invention, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "include" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof;

[0045] As introduced in the background technology, the fracture model in the prior art cannot realize the problem of preparing spiral and short oblique fracture models. In order to solve the above technical problems, the present invention proposes a fracture model making device.

[0046] Embodiment 1

[0047] In a typical embodiment of the present invention, reference is made to Figure 1As shown, a fracture model manufacturing device includes a base 1, which supports a clamping assembly 12. The clamping assembly 12 includes a support ring 5 installed on the base 1, and a clamping seat 7 is connected to one side of the support ring 5. The clamping seat 7 is communicated with the support ring 5, and the clamping seat 7 is rotatable relative to the support ring 5. The clamping seat 7 is a hollow part for the passage of an object to be fractured. The clamping assembly 12 is provided with at least two locations, and the clamping seat 7 is circumferentially provided with openings. Fasteners pass through the openings 6 to fix the object to be fractured 16. During the rotation of the clamping seat 7 relative to the support ring 5, the object to be fractured 16 is driven to rotate, thereby realizing the manufacturing of a spiral fracture model.

[0048] It is easy to understand that the manufacturing equipment also includes a clamping gasket 15, which is arranged between the object to be fractured 16 and the inner wall of the clamping seat 7. The fastener passes through the opening 6 and abuts against the clamping gasket 15. The opening is a threaded hole, and the fastener is a bolt. After passing through the threaded hole, the bolt is in close contact with the clamping gasket, thereby ensuring stable fixation of the object to be fractured.

[0049] refer to Figure 2 As shown, the clamping gasket 15 is formed by cutting a cylindrical member, and the cylindrical member is beveled from the end surface of the cylindrical member to form a plurality of clamping gaskets 15. In some examples, there may be three clamping gaskets 15, which are placed in the circumference of the object to be fractured 16. Of course, in other examples, there may be other numbers of clamping gaskets. It is easy to understand that the fasteners correspond one-to-one to the clamping gaskets 15, or a clamping gasket 15 is compressed by two or three fasteners.

[0050] Specifically, the cylindrical component can be a rubber part or other types of components. It is cut from the middle of the first end of the cylindrical component in an inclined outward manner toward the second end, and then cut from the first end of the cylindrical component in an inclined outward manner toward the second end. The planes of the cutting surfaces formed by the two cuts are intersecting.

[0051] In addition, refer to Figure 3 and Figure 4 As shown, the support ring 5 supports the clamping seat 7 through the bearing 13, the bearing 13 is a rolling bearing, the bearing 13 is fixedly connected to the support ring 5, the inner ring of the bearing 13 is matched with the outer ring surface of the clamping seat 7, the clamping seat 7 is specifically a circular ring with a set length, the length of the support ring 5 is slightly smaller than the length of the clamping seat, the circular ring has a plurality of openings along the radial direction, and along the radial surface of the clamping seat 7, the openings in two adjacent rows of openings 6 are staggered.

[0052] In this embodiment, two clamping assemblies 12 are provided. The two clamping assemblies 12 are relatively provided at the base 1 , and the distance between the support rings 5 ​​in the two clamping assemblies is smaller than the distance between the clamping seats 7 .

[0053] It should be noted that an extension frame 11 is provided on one side of the base 1, and the extension frame 11 has a set length. The extension frame 11 is specifically an extension rod. The extension frame 11 is vertically connected to the base 1, that is, the extension frame is provided along the width direction of the base, and can be specifically provided at the center position of the base 1. The extension frame 11 is movably connected to one end of the action rod 8, and can be specifically connected through a rotating shaft, so that the action rod 8 can swing relative to the extension frame under the action of an external force. A first knife body 10 is provided on the side of the action rod 8 facing the base, and the first knife body 10 has a blade. The first knife body 10 is provided along the length direction of the action rod, and the first knife body has a set width. The first knife body 10 is made of metal parts, and the first knife body acts on the object to be fractured during the movement of the action rod toward the base to realize the production of a comminuted fracture model;

[0054] In this embodiment, the side of the base 1 is connected to the extension frame 11 through a pin shaft. The extension frame can be replaced according to the thickness of the bone, and an extension frame of suitable quality can be selected.

[0055] Moreover, a counterweight rod 9 is provided on one side of the action rod 8 relative to the first blade body, and the counterweight rod 9 is vertically connected to the action rod. The counterweight rod 9 can be a round rod, and the counterweight block can be set on the counterweight rod. The number or quality of the counterweight block can be adjusted according to the thickness of the bones of the object to be fractured. The staff holds the action rod to lift the action rod, and passes the fractured object through the clamping assembly for stable clamping. After clamping, the staff moves the action rod 8 to a set height from the object to be fractured 16, releases the action rod 8, and moves from the first blade body toward the object to be fractured to achieve the production of a comminuted fracture model.

[0056] In this embodiment, the support ring 5 can move along the length direction of the base 1 to adjust the distance between two adjacent clamping assemblies 12 to be suitable for objects to be fractured of different sizes;

[0057] It is easy to understand that the base 1 includes a frame-shaped body, and a rod body 2 is respectively arranged on both sides of the length direction of the base 1, and the rod bodies on both sides are arranged parallel to each other. The base is connected to the rod body 2, and a support plate 4 is arranged at the bottom of the support ring. Sliders 3 are arranged on both sides of the bottom of the support plate 4. The two slide blocks 3 are set at a distance, and the slide blocks 3 can be slidably installed on the rod body 2.

[0058] In this embodiment, the base 1 is a frame-shaped body, and the base 1 is hollow. The base as a whole can be placed on a workbench, or directly on the ground; of course, in some examples, the base 1 can also be provided with a mounting hole to fix the base 1 on the workbench or the ground to ensure the overall stability;

[0059] It should be noted that in the process of making a comminuted fracture model, considering the need to support the object to be fractured from below, a pad can be set inside the base. The pad can be a metal block. The height of the pad can be the same as the height of the base. The pad is placed below the first knife body to support the object to be fractured from below.

[0060] In other examples, reference Figure 5 As shown, a lifting mechanism 17 is provided in the hollow of the base 1, a mounting block 18 is provided on the top of the lifting mechanism 17, the mounting block 18 supports the second blade body 19, and the second blade body 19 gradually applies a force to the object to be fractured 16 during the lifting process;

[0061] Because the lifting mechanism also has a set height, and during the placement of the object to be fractured 16, the second knife body 19 should avoid contact with the object to be fractured. For this purpose, a recess can be set on the workbench or the ground, and the lifting mechanism is installed in the recess, so that when the second knife body is retracted, it will not affect the normal installation of the object to be fractured.

[0062] It is easy to understand that the lifting mechanism 17 can be a lifting electric cylinder. By pressing the control switch of the lifting electric cylinder, the lifting electric cylinder can be controlled to rise. During the gradual raising process, a force is applied to the object to be fractured through the second knife body.

[0063] The second blade 19 also has a blade. Because the flatness of the cross section must be ensured during the production of the transverse or wedge-shaped fracture model, the blade width of the second blade is smaller than that of the first blade. The second blade is also made of metal parts.

[0064] Specifically, the plane where the second blade 19 is located is set along the width direction of the base 1, and when the second blade 1 is in tangent or fulcrum contact with the bone, a three-point bending model will be formed, which can realize the production of transverse or short oblique fracture models, which is related to the material, structural symmetry and soft tissue traction. Under the ideal state that the structure is homogeneous, symmetrical, and has no structural or tissue damage, the fracture occurs at the intermediate force point; when the second blade 19 is in tangent or curved contact with the bone, a four-point bending model will be formed, which usually forms a wedge-shaped or transverse or multi-segment fracture model, which is related to the weak point of the bone and the shape and position of the contact surface; the second blade 19 applies a force toward the object to be fractured, and the clamping seat works together (the clamping seat drives the object to be fractured to rotate), and according to the size of the rotational force, the object to be fractured realizes the production of a short oblique or long oblique fracture model; it should be noted that different fracture models can be produced according to the different torsion of the clamping seat and the distribution of the force of the second blade.

[0065] It is easy to understand that the clamping seat 7 is connected to the operating rod 14, and the operating rod 14 can be a round rod, and the operation has a set length to save effort, and is installed on the clamping seat 7, or welded and fixed to the outer surface of the clamping seat 7;

[0066] The manufacturing equipment provided in this embodiment comprises a base 1 that supports a clamping assembly 12. The clamping assembly 12 is hollow so as to allow an object to be fractured 16 to pass through the opening. Fasteners can pass through the opening to clamp and fix the object to be fractured, thereby ensuring that the object to be fractured is stably clamped. The clamping seat can rotate relative to the support ring. By rotating the clamping seat relative to the support ring, the clamped object to be fractured can be driven to rotate, thereby realizing the manufacturing of a spiral fracture model.

[0067] Embodiment 2

[0068] This embodiment provides a method for making an animal fracture model, using the working method of a fracture model making device described in the first embodiment, the object to be fractured 16 can be a model bone or a limb with skin and flesh (limbs of animals that have lost their lives), and includes the following contents:

[0081] Alternatively, the second blade applies a force toward the object to be fractured, and the clamping seat works together (the clamping seat drives the object to be fractured to rotate) so that a short oblique or long oblique fracture model of the object to be fractured is produced.
