Description

Technical Field

[0001] This application relates to the field of pet fracture fixation technology, and in particular to an external fixation device for pet fractures. Background Technology

[0002] The core purpose of immobilization after a pet fracture is to maintain the position of the bone after reduction, create a stable environment for fracture healing, and avoid secondary injury.

[0003] After a pet's leg is fractured, a bandage is usually wrapped around the pet's leg to straighten the leg and prevent the broken bone from shifting. Because the bandage is wrapped tightly, the pet's leg has poor ventilation. The unventilated environment will keep the pet's leg skin in a hot and humid state for a long time, which will nourish fungi and make the immobilization time long.

[0004] Therefore, those skilled in the art have provided an external fixation device for pet fractures to address the problems mentioned in the background section. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides an external fixation brace for pet fractures, which can compress the pet's fractured leg through pressure columns and rods, helping to straighten the leg, avoid dislocation, maintain the reduced position to promote callus formation, and at the same time prevent the broken bone from shifting again when the pet is active.

[0006] This application provides a pet fracture external fixation bracket with the following technical solution:

[0007] A pet fracture external fixation brace includes a front disc and a tail disc with an annular structure. The front disc is slidably connected to six first sliders arranged in a ring. Each of the six first sliders has a fixed rod fixed to its end. Each of the six fixed rods is slidably connected to a movable rod. Each of the six movable rods has a pressure rod fixed to its end. Each of the six pressure rods has a fixed post fixed to its other end. Each of the six fixed posts has a second slider fixed to its end. Each of the six second sliders is slidably connected to the tail disc.

[0008] Each of the six pressure rods and six pressure columns is fitted with a strap. One end of the strap is fixed to a U-shaped insert frame, and the other end of the strap passes through the interior of the insert frame.

[0009] Preferably, a second Velcro fastener is fixed to the inner surface of one end of the strap, and a first Velcro fastener is fixed to the outer surface of the other end of the strap for attaching with the second Velcro fastener.

[0010] In this invention, after the pressure post and pressure bar are tightened by the straps, the first and second Velcro fasteners are used to attach them together, which can effectively prevent the straps from loosening and ensure the fixation effect on the fractured position of the pet's leg.

[0011] Preferably, the outer surfaces of the pressure rod and the pressure column are both fixed with elastic sleeves, and the fixing rod and the fixing column are both V-shaped structures.

[0012] Preferably, one end of the movable rod is fixedly connected to a limiting block, and the limiting block is slidably connected to the inner surface of the pressure column.

[0013] Preferably, both the front disc and the rear disc have at least six grooves.

[0014] Preferably, a rotating ring is rotatably connected to the outer wall of the tail disc, and six connecting rods are rotatably connected to one side of the rotating ring. The other ends of the six connecting rods are respectively rotatably connected to the outer surfaces of the six second sliders.

[0015] Preferably, the front disc is rotatably connected to a screw, which is threadedly connected to one of the first sliders.

[0016] In this invention, by rotating the screw, one of the first sliders slides close to the center of the front plate, which drives one of the fixed rods and pressure columns to move, and drives the movable rods and pressure columns to move together. Under the action of the rotating ring and the connecting rod, the remaining five pressure columns, five movable rods and five pressure columns move and retract together, binding and fixing them to the pet's legs, thus clamping and fixing the legs.

[0017] In summary, this application includes the following beneficial technical effects:

[0018] 1. This application has a good effect on fixing and reducing fractured legs in pets. It can compress the fractured leg of the pet by pressing the column and the rod, which helps to straighten the leg, avoid dislocation, maintain the reduced position to promote callus formation, and prevent the broken bone from shifting again when the pet moves.

[0019] 2. High adaptability: The movable rod and the pressure post are slidably connected, allowing the pressure post to be moved so that the movable rod extends out of the pressure post. The distance between the front and rear discs, the pressure post and the pressure post can be adjusted, and the leg binding distance can be flexibly adjusted according to the pet's leg length.

[0020] 3. It has a breathable function. When the six pressure posts and pressure bars are arranged in a ring, there are gaps between adjacent pressure bars or pressure posts, which can provide breathable space for the pet's leg fracture area. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] like Figure 1-5 As shown, this application discloses an external fixation brace for pet fractures, including a ring-shaped front plate 1 and a tail plate 7. The front plate 1 is slidably connected to six first sliders 2 arranged in a ring. Each of the six first sliders 2 has a fixing rod 3 fixed to its end. Each of the six fixing rods 3 is slidably connected to a movable rod 11. Each of the six movable rods 11 has a pressure rod 10 fixed to its end. Each of the six pressure rods 10 has a fixing post 9 fixed to its other end. Each of the six fixing posts 9 has a second slider 8 fixedly connected to its end. Each of the six second sliders 8 is slidably connected to the tail plate 7. The pressure rods 10 and pressure columns 12 between the front disc 1 and the tail disc 7 are connected together by the movable rod 11 to form a whole. The six pressure columns 12 and pressure rods 10 form a ring, with gaps between adjacent pressure rods 10 or pressure columns 12 for ventilation. The front disc 1, the six pressure columns 12, the six pressure rods 10 and the tail disc 7 are put on the pet's fractured leg in sequence. The six pressure columns 12 and the six pressure rods 10 compress the fractured part of the pet's leg to straighten the leg, prevent dislocation, maintain the leg's repositioned position and promote callus formation.

[0030] Each of the six pressure rods 10 and the six pressure posts 12 is fitted with a strap 13. One end of the strap 13 is fixed with a U-shaped insert frame 5, and the other end of the strap 13 passes through the interior of the insert frame 5. A second Velcro 6 is fixed to the inner surface of one end of the strap 13, and a first Velcro 4 is fixed to the outer surface of the other end of the strap 13 for attaching with the second Velcro 6.

[0031] By adopting the above technical solution, the front plate 1, six pressure columns 12, six pressure rods 10 and the tail plate 7 are sequentially placed on the pet's leg fracture site. The first slider 2 slides inside the front plate 1 and the second slider 8 slides inside the tail plate 7. The user tightens the ends of the two straps 13 until the six pressure rods 10 and six pressure columns 12 are tightened to compress and squeeze the pet's fractured leg, straightening the leg and preventing the broken bone from shifting again when the pet moves. After the two straps 13 are used to tighten the six pressure columns 12 and six pressure rods 10, the second Velcro 6 is attached to the first Velcro 4 to prevent the straps 13 from loosening and to fix the pet's leg fracture site.

[0032] In addition, the movable rod 11 is slidably connected to the pressure column 12, which allows the pressure rod 10 to be moved so that the movable rod 11 extends a certain distance beyond the pressure column 12. This adjusts the distance between the front disc 1 and the tail disc 7, thereby adjusting the distance between the pressure rod 10 and the pressure column 12. The pressure rod 10 and the pressure column 12 can be adjusted appropriately according to the length of the pet's leg to match the distance of the leg binding, making it easier to fix the pet's fractured leg.

[0033] To ensure the comfort of the leg wrap, elastic sleeves 19 are fixed to the outer surfaces of the pressure bar 10 and the pressure post 12. The fixing rod 3 and the fixing post 9 are both V-shaped structures. An elastic sleeve 19 with elasticity is set on the outer surface of the pressure bar 10 and the pressure post 12 and fixed to the pet's fractured leg to provide comfort. The V-shaped fixing post 9 and the fixing rod 3 bring the pressure post 12 and the pressure bar 10 closer to the center of the front plate 1, so that after the first slider 2 and the second slider 8 move, they drive the pressure post 12 and the pressure bar 10 to squeeze the pet's leg.

[0034] To prevent the movable rod 11 from detaching from the pressure column 12, one end of the movable rod 11 is fixedly connected to a limiting block 18, which is slidably connected to the inner surface of the pressure column 12.

[0035] In order to connect multiple pressure columns 12 and pressure rods 10, both the front plate 1 and the rear plate 7 are provided with at least six sliding grooves 16.

[0036] Example 2

[0037] Unlike Embodiment 1, which uses straps 13 to tighten the six pressure posts 12 and six pressure rods 10, in this embodiment, see [reference needed]. Figure 2A rotating ring 15 is rotatably connected to the outer wall of the tail plate 7. Six connecting rods 14 are rotatably connected to one side of the rotating ring 15. The other ends of the six connecting rods 14 are rotatably connected to the outer surfaces of the six second sliders 8 respectively. A screw 17 is rotatably connected to the front plate 1. The screw 17 is threadedly connected to one of the first sliders 2. The six connecting rods 14 on one side of the rotating ring 15 are connected to the six second sliders 8 respectively. The counterclockwise rotation of the rotating ring 15 drives the six connecting rods 14 to move, causing the six second sliders 8 to slide together, which drives the six pressure rods 10 to move and retract together, thereby causing the six pressure columns 12 to retract together.

[0038] Specifically, when the front plate 1, six pressure pillars 12, six pressure rods 10, and the tail plate 7 are sequentially placed on the pet's leg fracture site, the screw 17 can be rotated to make one of the first sliders 2 slide closer to the center of the front plate 1, causing one of the fixed rods 3 and pressure pillars 12 to move, which in turn causes the movable rods 11 and pressure rods 10 to move together. Under the action of the rotating ring 15 and the connecting rod 14, the remaining five pressure pillars 12, five movable rods 11, and five pressure rods 10 move and retract together, binding and fixing them to the pet's leg, thus clamping and fixing the leg.

[0039] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0041] Working principle: The front plate 1, six pressure posts 12, six pressure rods 10, and tail plate 7 are sequentially placed on the pet's leg fracture site. This causes the first slider 2 to slide inside the front plate 1 and the second slider 8 to slide inside the tail plate 7. The user then tightens the ends of the two straps 13 until the six pressure rods 10 and six pressure posts 12 are tightened, compressing and straightening the pet's fractured leg to prevent the broken bone from shifting again during the pet's movement. After the two straps 13 are used to tighten the six pressure posts 12 and six pressure rods 10, the second Velcro 6 is attached to the first Velcro 4 to prevent the straps 13 from loosening, thus fixing the pet's leg fracture site.
