Description

Technical Field

[0001] The present invention belongs to the technical field of animal limb fixation, and relates to an adjustable external fixation splint device for animal limb fractures. Background Art

[0002] After an animal's limb is fractured, surgery and subsequent rehabilitation treatment are often required. To ensure the recovery of the fractured area, the limb is wrapped and clamped with an external fixation splint at the fracture site to avoid secondary injury. Currently, the commonly used external fixation methods are plaster fixation and splint fixation, which are completed by winding a bandage. Although plaster fixation has the advantages of low price, easy plasticity, and good conformability, it is widely used. However, plaster has poor air permeability and is a disposable item, which cannot meet the needs of various animals. Moreover, when removing the plaster, it is necessary to soak it in water first and then use tools to remove it, and the operation is very cumbersome. If the operation is improper, it is easy to cause secondary injury. And for the treatment process that requires dressing change, the operation is very inconvenient. While splint fixation has the advantages of good air permeability, convenient disassembly and assembly, easy recycling and reuse, and can apply appropriate pressure to the limb part, which helps the healing of the fracture while fixing the fractured part. However, the commonly used splints at present are generally attached to the animal's limb as a whole. Since the limbs of different types of animals are thick and thin, long and short, and the body sizes of the same type of animals are also large and small, there will be a large difference in limb size. At the same time, due to the large number of animal categories and the large difference in limb shapes, traditional splint fixation requires making appropriate splints according to corresponding needs, which not only delays time but also is troublesome to make, and is not conducive to recycling and reuse. Therefore, we propose an adjustable external fixation splint device for animal limb fractures to solve the above problems. Summary of the Invention

[0034] The following uses specific specific examples to illustrate the implementation manners of the present invention. Those skilled in the art can easily understand the other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present invention in a schematic manner. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0035] Example 1: As Figures 1 - 3 , Figure 7 and Figure 8 shown, an adjustable external fixation splint device for animal limb fractures includes a first folding plate 1, a plurality of splint strips 2, a plurality of rotating blocks 3, a second folding plate 4, a first slider 8 and a second slider 10. The first folding plate 1 and the second folding plate 4 are symmetrically arranged. A set of fixing parts for fixing the whole splint are provided on the first folding plate 1 and the second folding plate 4. Sliding slots 5 are formed on one side of the first folding plate 1 and the second folding plate 4. The first slider 8 is limited to slide in the sliding slot 5 on the first folding plate 1, and the second slider 10 is limited to slide in the sliding slot 5 on the second folding plate 4. A plurality of rotating blocks 3 are arranged side by side and rotatably between the first slider 8 and the second slider 10, and the plurality of rotating blocks 3 are rotatably connected to each other. A plurality of splint strips 2 are arranged side by side and positioned on the plurality of rotating blocks 3, and at the same time, the connected rotating blocks 3 can be rotationally limited. By arranging different numbers of splint strips 2 side by side and fittingly, an adaptable external fixation splint can be formed according to different animals and different body-shaped limbs. Two vertically arranged first sponge pads 7 are symmetrically provided on the contact surfaces of the plurality of splint strips 2 with the animal limb, and two horizontally arranged second sponge pads 30 are symmetrically provided on the contact surfaces of the first folding plate 1 and the second folding plate 4 with the animal limb. Through the arrangement of the first sponge pads 7 and the second sponge pads 30, the whole splint can achieve a comfortable and fitting effect when fixing the animal limb, and avoid hard extrusion contact with the animal limb.

[0036] In one aspect of this embodiment, the fixing part includes a fixing band 6 provided on the side of the first folding plate 1 away from the second folding plate 4. A sticking rough surface 22 is provided on one side of the fixing band 6, and a sticking hook surface 31 for sticking and cooperating with the sticking rough surface 22 is provided at the bottom of the side of the second folding plate 4 away from the sliding slot 5. After assembling the required splint strips 2, the positioning of the first folding plate 1 and the second folding plate 4 is also completed. Then, the splint strips 2 are attached to the fracture of the animal limb, and then the first folding plate 1 and the second folding plate 4 are rotated to also contact the animal limb to complete multi-sided wrapping and clamping. Finally, the fixing band 6 is pulled around the animal limb and the sticking rough surface 22 is stuck to the sticking hook surface 31, so as to complete the preliminary fixing of the whole splint, and then the whole splint is wrapped and fixed with gauze.

[0037] In one aspect of this embodiment, sliding grooves 20 are provided on the upper and lower inner walls of the sliding notch 5 on the first folding plate 1 and the second folding plate 4. The top and bottom of the first slider 8 and the second slider 10 are integrally formed with limiting sliders 11 that are slidably connected to the sliding grooves 20. Through the sliding connection of the limiting sliders 11 in the sliding grooves 20, when moving the first folding plate 1 or the second folding plate 4, it can prevent the first slider 8 from disengaging from the sliding connection with the first folding plate 1 and prevent the second slider 10 from disengaging from the sliding connection with the second folding plate 4, ensuring the stability of the entire fixed splint during use.

[0038] The present invention can be used in the field of adjustable external fixation splint devices for animal limb fractures, and can also be applicable to other fields of the present invention.

[0039] Embodiment 2: This embodiment is a further improvement of the previous embodiment: As Figures 1 - 6 shown, rotating grooves 12 are provided on one side of a plurality of rotating blocks 3 and the first slider 8 close to the second slider 10. A rotating shaft 15 is rotatably connected vertically in each of the plurality of rotating grooves 12. One side of the plurality of rotating blocks 3 and the second slider 10 close to the first slider 8 are integrally formed with connecting convex portions 13 that are adapted to the rotating grooves 12, and the plurality of connecting convex portions 13 are respectively sleeved on the corresponding rotating shafts 15. The plurality of rotating blocks 3 are rotatably connected to each other and to the first slider 8 and the second slider 10 respectively by the rotating shafts 15, enabling rotation at each connection point, thereby achieving the effect of multi-joint rotation. To ensure the normal rotation of multiple rotation points, one side of the plurality of rotating blocks 3 and the first slider 8 close to the rotating grooves 12 are processed with semi-circular chamfers, and one side of the plurality of connecting convex portions 13 close to the corresponding rotating grooves 12 is also processed with semi-circular chamfers. Two positioning holes 14 are symmetrically provided vertically on one side of the plurality of rotating blocks 3. A docking port 9 adapted to be snap-fitted with the rotating blocks 3 is provided on one side of the splint strip 2. Two positioning rods 17 that are symmetrically fixedly connected to the inner wall of the docking port 9 and are in positioning plug-in cooperation with the corresponding positioning holes 14 are provided. First, when installing the splint strip 2, align the docking port 9 on the splint strip 2 with the rotating blocks 3 for positioning and snap-fitting, and at the same time, insert the two positioning rods 17 into the two positioning holes 14 respectively to complete the positioning of the splint strip 2. At this time, the splint strip 2 can be exactly snap-fitted between two adjacent rotating blocks 3.

[0040] In one aspect of this embodiment, fixed screws 16 are fixedly connected to one side of multiple rotating blocks 3 and the second slider 10. On the side of the fixed screw 16 close to the connecting convex portion 13, insertion holes 18 that are in threaded engagement with the fixed screw 16 are formed in the inner wall of the docking interface 9. A locking nut 19 that is used in cooperation with the fixed screw 16 is rotatably connected to the side of the clamping strip 2 away from the docking interface 9. When the clamping strip 2 is clamped onto the rotating block 3, the fixed screw 16 is simultaneously inserted into the insertion hole 18 and corresponds to the locking nut 19. At the same time, one end of the positioning rod 17 can also be inserted into the positioning hole 14. At this time, the locking nut 19 can be rotated. Through the threaded connection between the locking nut 19 and the fixed screw 16, the clamping strip 2 can be pushed to move, thereby completing the fixed connection between the clamping strip 2 and the rotating block 3. After the clamping strip 2 is connected, since the clamping strip 2 is clamped between two adjacent rotating blocks 3, and the positioning rod 17 is inserted into the positioning hole 14 on the left rotating block 3, and the clamping strip 2 is sleeved on the fixed screw 16 on the right rotating block 3. Therefore, after the fixed connection between the clamping strip 2 and the rotating block 3 is completed, the connection between the corresponding two rotating blocks 3 cannot rotate. Furthermore, after multiple clamping strips 2 are connected, the formed fixed clamp can be in a stable state. In addition, the clamping strip 2 can be equipped with different lengths according to the usage requirements. For example, the limbs of a cat are shorter, and a shorter clamping strip 2 can be used for fixation. The limbs of a dog are longer, and a longer clamping strip 2 can be used for fixation. Therefore, clamping strips 2 with appropriate lengths and quantities can be selected for assembly according to different types of animals or animals of the same type with different body sizes, thereby improving the flexibility of use.

[0041] Embodiment 3: This embodiment is a further improvement of the previous embodiment: As Figures 1 - 9As shown, strip-shaped notches 21 communicating with the corresponding sliding slots 5 are provided on one side of the first folding plate 1 and the second folding plate 4. The strip-shaped notches 21 are used for the movement of the fixing screw 16 to make way. On the side of the first folding plate 1 and the second folding plate 4 away from the corresponding sliding slots 5, a set of clamping components for limiting and clamping the fixing screw 16 are provided. When adjusting the positions of the first folding plate 1 and the second folding plate 4, the first slider 8 can drive part of the rotating block 3 to move in the corresponding sliding slot 5. Similarly, the second slider 10 can also drive part of the rotating block 3 to move in the corresponding sliding slot 5, so as to adjust the spacing equal to the number of assembled splint strips 2, facilitating the positioning and clamping of the splint strips 2 on the rotating block 3. During the adjustment process, the fixing screw 16 can move in and out of the strip-shaped notch 21 for easy adjustment. And after adjusting the positions of the first folding plate 1 and the second folding plate 4, one of the fixing screws 16 moved into the strip-shaped notch 21 can be positioned and clamped, thereby completing the position limitation of the first folding plate 1 and the second folding plate 4 on a certain rotating block 3, so that the first folding plate 1 and the second folding plate 4 can rotate at the contact positions with the corresponding splint strips 2 to complete the multi-directional wrapping and clamping of the animal limb.

[0042] In one aspect of this embodiment, the clamping component includes a clamping block 23 slidably connected to one side of the first folding plate 1 or the second folding plate 4. A clamping interface 24 cooperating with the fixing screw 16 is provided at the bottom of the clamping block 23. Upper abutting blocks 27 and lower abutting blocks 25 located above and below the corresponding clamping blocks 23 are fixedly connected to one side of the first folding plate 1 and the second folding plate 4. Two clamping holes 28 are symmetrically provided at the tops of the upper abutting blocks 27 and the lower abutting blocks 25. Two clamping rods 26 that are clamped and cooperate with the corresponding clamping holes 28 are symmetrically and fixedly connected to the top and bottom of the clamping block 23. Rubber rings 29 are fixedly provided in a plurality of clamping holes 28. After adjusting the positions of the first folding plate 1 and the second folding plate 4, at this time, the clamping block 23 can be directly pushed downward by hand to position and clamp one of the fixing screws 16 in the clamping interface 24. At this time, the positions of the first folding plate 1 and the second folding plate 4 can be limited to prevent them from moving on the rotating block 3. Such as Figure 10 and Figure 11As shown in the figure, the positions of the clamping blocks 23 on the first folding plate 1 and the second folding plate 4 are different. To ensure that both the first folding plate 1 and the second folding plate 4 can rotate normally, the clamping block 23 on the first folding plate 1 can only fix the second fixing screw 16 adjacent to the leftmost clamping strip 2. If the adjacent first fixing screw 16 is fixed, the first folding plate 1 cannot rotate because the rotating block 3 has been limited by the leftmost clamping strip 2 and cannot rotate. Therefore, the adjacent first fixing screw 16 cannot be positioned and clamped. During the rotation of the first folding plate 1, the normal rotation of the first folding plate 1 can be ensured by the yielding of the strip-shaped notch 21. The clamping block 23 on the second folding plate 4 can fix the first fixing screw 16 adjacent to the rightmost clamping strip 2 because the rotating block 3 is not limited by the rightmost clamping strip 2 and can rotate, thereby enabling the second folding plate 4 to rotate normally. When the clamping block 23 slides downward, it can limit and clamp the fixing screw 16, and make the lower clamping rod 26 inserted into the clamping hole 28 on the lower abutting block 25, improving the clamping stability of the fixing screw 16. On the contrary, when the clamping block 23 slides upward, the limit clamping of the fixing screw 16 can be released, facilitating the movement adjustment of the first folding plate 1 or the second folding plate 4, and at the same time making the upper clamping rod 26 inserted into the clamping hole 28 on the upper abutting block 27. By arranging a rubber ring 29 in the clamping hole 28, after the clamping rod 26 is inserted into the clamping hole 28, the stable positioning of the clamping block 23 can be improved by the extrusion friction with the rubber ring 29, thus facilitating better operation.

[0043] Embodiment 4: This embodiment is a further improvement of the previous embodiment: As Figures 1 - 11 shown, the edges of the mutually adjacent sides of the first folding plate 1 and the second folding plate 4 are all chamfered. As Figure 10 , Figure 11 shown, since after the first folding plate 1 and the second folding plate 4 are fixed in position, one side of them is in contact with one side of the clamping strip 2. To ensure the normal rotation of the first folding plate 1 and the second folding plate 4, arc chamfers are provided at the corners of the first folding plate 1 and the second folding plate 4, which can ensure that the first folding plate 1 and the second folding plate 4 can rotate normally in contact with the clamping strip 2 when the first folding plate 1 and the second folding plate 4 rotate and fit to fix the animal limb. Of course, during the design process, by changing the position fixing of the fixing screw 16, that is, changing the clamping position of the clamping block 23, a certain rotation gap can be reserved between one side of the first folding plate 1 and the second folding plate 4 and the adjacent clamping strip 2, so as to ensure normal rotation. This design of reserving a gap will appropriately increase the use length of the entire splint. Therefore, which method to adopt can be selected according to the actual design requirements, and no specific limitation is made here.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the present technical solution, and they should all be covered within the scope of the claims of the present invention.
