Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to an orthopedic reduction and fixation orthopedic device. Background Art

[0002] Orthopedic reduction and fixation orthopedic devices are important auxiliary devices used in orthopedic clinical practice for patients with leg fractures. Their main function is to fix the fracture site after reduction, maintain the stability of the fracture ends, create good conditions for fracture healing, and at the same time assist in correcting abnormal limb postures to a certain extent and promote the recovery of patients' limb function.

[0003] During leg fracture treatment, patients often experience inversion or eversion of the foot due to muscle imbalances and improper fixation, resulting in a pigeon-toed or pigeon-toed posture. Existing fixation devices often provide little more than simple foot wrapping, lacking specific adjustment and locking mechanisms for the foot's angle. This makes it difficult to control foot posture and effectively prevent inversion or eversion. This not only impairs fracture healing but also easily leads to gait abnormalities after fracture healing, hindering the recovery of limb function. Summary of the Invention

[0004] In response to the deficiencies of the prior art, the present invention provides an orthopedic reduction and fixation device for orthopedics, which solves the problem of inversion or eversion of the sole of the foot, thereby forming an inward or outward-facing posture, making it difficult to control the posture of the sole of the foot, and unable to effectively prevent the occurrence of inversion or eversion, affecting the normal healing of fractures. It is also easy to cause patients to have abnormal gait after the fracture heals, affecting the normal recovery of limb function.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an orthopedic reduction and fixation orthopedic correction device, comprising:

[0006] a second fixing plate, wherein both ends of the top of the second fixing plate are rotatably connected to connecting pieces, a second lining is fixedly connected to the inner side of the second fixing plate, the second lining is rotatably connected to the two connecting pieces, a first fixing plate is rotatably connected between the two connecting pieces, the first lining is fixedly connected to the inner side of the first fixing plate, a reinforcing fixing strap is installed on the front side between the first lining and the first fixing plate, and a locking fixing strap is installed on the lower rear side between the second fixing plate and the second lining;

[0007] The locking mechanism includes two fixed blocks, the tops of the two fixed blocks are penetrated and threaded with fastening bolts, and the bottom ends of the fastening bolts penetrate and extend to the bottom of the fixed blocks, the bottom sides of the two fastening bolt surfaces are rotatably connected to locking rods, the bottoms of the two locking rods are rotatably connected to rotating parts, and a foot fixing sleeve is fixedly connected between the two rotating parts.

[0008] Preferably, the locking mechanism includes two connecting columns, both ends of the two connecting columns are threadedly connected with connecting screws, the top two connecting screws and the opposite sides of the bottom two connecting screws are fixedly connected with rotating parts, the top two rotating parts are fixedly connected to the second fixed plate, the bottom two rotating parts are fixedly connected to the foot fixing sleeve, and the surfaces of the four connecting screws are threadedly connected with limiting nuts.

[0009] Preferably, a sliding groove is provided on the opposite side of the two locking rods, and the left and right sides of the outer side of the second fixed plate are fixedly connected to the limiting sliders, and the two limiting sliders pass through the sliding groove and extend to the outside of the locking rod, and the two limiting sliders are slidably connected to the sliding groove.

[0010] Preferably, a lower fixing strap is installed at a middle position on the rear side between the second fixing plate and the second lining.

[0011] Preferably, an upper fixing strap is installed on the rear side between the first lining and the first fixing plate.

[0012] Preferably, a foot fixing pad is provided inside the foot fixing sleeve, and the size of the foot fixing pad is consistent with the size of the inside of the foot fixing sleeve, so that the foot fixing pad can be clamped in the foot fixing sleeve.

[0013] Preferably, the left and right sides of the foot fixing sleeve are fixedly connected with connecting buckles, and a foot fixing strap is provided between the two connecting buckles.

[0014] Preferably, the first liner and the second liner are both made of medical silicone material, and the surfaces of the first liner and the second liner are both provided with ventilation holes, and the diameter of the ventilation holes is 1-2 mm.

[0015] Preferably, the first fixing plate and the second fixing plate are both made of carbon fiber composite material, and the thickness of the first fixing plate and the second fixing plate is 3-5 mm.

[0016] Preferably, the foot fixing pad is provided with a variety of different sizes and specifications, and the foot fixing pad and the foot fixing sleeve are detachably connected, so that an appropriate foot fixing pad can be selected according to the size of the user's foot.

[0017] Working Principle: First, loosen the reinforced fixation strap, upper fixation strap, lower fixation strap, locking fixation strap and foot fixation strap, then put them on the patient's legs and make the feet fit the foot fixation pad in the foot fixation sleeve;

[0018] After further tightening and sticking the foot fixing strap, loosen the bolts on the connecting piece and adjust the angle between the first fixing plate and the second fixing plate according to the leg shape. After the adjustment is completed, tighten the bolts on the connecting piece and tighten and stick the reinforced fixing strap, upper fixing strap, lower fixing strap and locking fixing strap in turn.

[0019] Finally, tighten the fastening bolts in the locking mechanisms on the left and right sides respectively. The fastening bolts perform threaded movement in the fixing blocks. As the fastening bolts are loosened or tightened, the locking rods are squeezed downward or stretched upward. As the locking rods move, the angle between the locking rods and the rotating part changes, thereby driving the foot fixing sleeves to deviate left and right, thereby adjusting the foot angle.

[0020] In another embodiment, the upper and lower limit nuts are twisted in the opposite direction of the connecting column, and then the connecting column is rotated, so that the connecting column and the two connecting screws perform threaded movement, shortening the distance between the two connecting screws. After the connecting screws on both sides are adjusted, the upper and lower limit nuts are twisted toward the connecting column to limit and fix the connecting screws and the connecting column, thereby completing the adjustment and fixation of the foot.

[0021] The present invention provides an orthopedic reduction and fixation device. It has the following beneficial effects:

[0022] 1. The present invention adopts a locking mechanism in conjunction with a foot fixing sleeve. The locking rod and rotating member in the locking mechanism can adjust the angle. The foot fixing sleeve can stably wrap the sole of the foot and limit the angle of the sole of the foot so that the sole of the foot is consistent with the leg. It effectively corrects the inversion or eversion of the sole of the foot that is prone to occur after a leg fracture and prevents the formation of an inward or outward-turned posture. The existing technology's fixing devices mostly simply wrap the sole of the foot and lack the ability to adjust the angle and lock. This solves the problem of difficulty in controlling the sole of the foot and the gait abnormality that may occur after fracture healing.

[0023] 2. This invention utilizes a first fixing plate and a second fixing plate that are rotatably connected via a connector, enabling two-stage angle adjustment. This allows for greater adaptability to various leg shapes. Combined with the technical solutions of reinforced and locked fixing straps, this achieves multi-angle fixation and enhanced stability. Existing technologies, which mostly use rigid fixing structures, address the issues of limited adjustment flexibility and inability to adapt to changes in posture during limb recovery.

[0024] 3. The present invention utilizes a first and second inner lining made of medical silicone, which is soft and conforms to the contours of the leg. The surface is provided with ventilation holes, making the device more comfortable on the leg and reducing friction and pressure on the skin. The ventilation holes also promote air circulation. Existing inner liners are often rigid and lack ventilation to restrict the leg. This solves the problem of poor breathability, which can easily cause skin stuffiness, itching, or inflammation after prolonged use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see the attached Figure 1 -Attached Figure 4 The embodiment of the present invention provides an orthopedic reduction and fixation orthopedic correction device, comprising:

[0035] A second fixing plate 9, both ends of the top of the second fixing plate 9 are rotatably connected to connecting members 4, a second lining 13 is fixedly connected to the inner side of the second fixing plate 9, the second lining 13 is rotatably connected to the two connecting members 4, a first fixing plate 2 is rotatably connected between the two connecting members 4, a first lining 1 is fixedly connected to the inner side of the first fixing plate 2, a reinforcing fixing strap 3 is installed on the front side between the first lining 1 and the first fixing plate 2, and a locking fixing strap 8 is installed on the lower rear side between the second fixing plate 9 and the second lining 13;

[0036] The locking mechanism 6 includes two fixed blocks 6013, and the tops of the two fixed blocks 6013 are penetrated and threadedly connected with fastening bolts 6015, and the bottom ends of the fastening bolts 6015 penetrate and extend to the bottom of the fixed blocks 6013. The bottom sides of the two fastening bolts 6015 are rotatably connected to the locking rods 6011, and the bottoms of the two locking rods 6011 are rotatably connected to the rotating parts 6016, and the foot fixing sleeve 5 is fixedly connected between the two rotating parts 6016.

[0037] Specifically, the reinforced fixing strap 3 and the upper fixing strap 14 are both Velcro. After the device is put into the leg and the angle of the first fixing plate 2 and the second fixing plate 9 is adjusted, they are tightened and fixed, which can apply a restraining force from the front side of the upper leg of the calf. In conjunction with the upper fixing strap 14, the upper leg is firmly fixed between the first fixing plate 2 and the first lining 1 to prevent the upper leg of the calf from shifting during subsequent activities, thereby ensuring the stability of the fixation. The second fixing plate 9 mainly supports and fixes the lower leg of the calf. The connecting member 4 adjusts the angle of the first fixing plate 2 and the second fixing plate 9 through screws. Loosening the corresponding screws can adjust the angle of the fixing plate. After tightening, it is fixed and cannot be rotated and adjusted, thereby achieving the adaptation of the device to the leg.

[0038] A sliding groove 6012 is provided on the opposite side of the two locking rods 6011, and the left and right sides of the outer side of the second fixed plate 9 are fixedly connected to the limiting sliders 6014. The two limiting sliders 6014 pass through the sliding groove 6012 and extend to the outside of the locking rod 6011. The two limiting sliders 6014 are slidably connected to the sliding groove 6012.

[0039] Specifically, after the legs and feet are initially fixed, the fastening bolt 6015 is turned for adjustment, and the fastening bolt 6015 moves in the internal thread of the fixing block 6013, driving the locking rod 6011 to squeeze downward or stretch upward, and the angle change between the locking rod 6011 and the rotating part 6016 is transmitted to the foot fixing sleeve 5, thereby realizing the left and right offset adjustment of the foot, correcting the inversion or eversion of the sole of the foot, and finally fixing the foot angle. When the locking rod 6011 moves with the fastening bolt 6015, the limiting slider 6014 and the sliding groove 6012 slide in the sliding groove 6012, which can limit the moving trajectory of the locking rod 6011, ensuring that the locking rod 6011 moves smoothly in the horizontal direction, and avoiding its offset causing deviation in the foot adjustment angle.

[0040] A lower fixing strap 7 is installed at a middle position on the rear side between the second fixing plate 9 and the second inner lining 13 .

[0041] Specifically, the lower fixing strap 7 is a Velcro, and the lower fixing strap 7 is tightened and adhered to the middle position of the rear side of the lower leg.

[0042] An upper fixing strap 14 is installed on the rear side between the first lining 1 and the first fixing plate 2 .

[0043] Specifically, the locking and fixing strap 8 is also a Velcro, which applies a fixing force from the middle position of the lower leg.

[0044] A foot fixing pad 12 is provided inside the foot fixing sleeve 5 . The size of the foot fixing pad 12 is consistent with the size of the inside of the foot fixing sleeve 5 , so that the foot fixing pad 12 can be engaged in the foot fixing sleeve 5 .

[0045] Specifically, the outer edge position of the foot fixing pad 12 is consistent with the inner size of the foot fixing sleeve 5 , so each foot fixing pad 12 can be inserted into the foot fixing sleeve 5 .

[0046] The left and right sides of the foot fixing sleeve 5 are fixedly connected with connecting buckles 11 , and a foot fixing strap 10 is provided between the two connecting buckles 11 .

[0047] Specifically, after the foot is fitted with the foot fixing pad 12, the foot fixing strap 10 is tightened and adhered between the two connecting buckles 11, which can tighten the foot fixing sleeve 5 so that the foot fixing sleeve 5 tightly wraps the sole of the foot and fixes the sole of the foot in the foot fixing sleeve 5 to prevent the sole of the foot from shifting during the adjustment process.

[0048] The first liner 1 and the second liner 13 are both made of medical silicone material, and the surfaces of the first liner 1 and the second liner 13 are both provided with ventilation holes, and the diameter of the ventilation holes is 1 mm.

[0049] The first fixing plate 2 and the second fixing plate 9 are both made of carbon fiber composite material, and the thickness of the first fixing plate 2 and the second fixing plate 9 is 3 mm.

[0050] The foot fixing pad 12 is provided with a variety of different sizes and specifications, and the foot fixing pad 12 and the foot fixing sleeve 5 are detachably connected, so that the appropriate foot fixing pad 12 can be selected according to the size of the user's foot.

[0051] Specifically, when the foot is placed in the foot fixing sleeve 5, the foot fixing pad 12 fits the sole of the foot. The different sizes of the replaceable foot fixing pad 12 can adapt to the soles of feet of different sizes, ensuring that the sole of the foot and the foot fixing pad 12 are in close contact. During the tightening and angle adjustment process of the foot fixing sleeve 5, the friction between the sole of the foot and the foot fixing sleeve 5 is reduced, thereby improving comfort.

[0052] Example 2:

[0053] Please see the attached Figure 5 -Attached Figure 6 On the basis of the first embodiment, this embodiment is also intended to solve the problem of inward or outward rotation of the sole of the foot after a leg fracture, forming an inward or outward-turned posture. In order to solve this problem, this embodiment provides another solution: the locking mechanism 6 includes two connecting columns 6021, both ends of the two connecting columns 6021 are threadedly connected to connecting screws 6024, the two top connecting screws 6024 and the opposite sides of the two bottom connecting screws 6024 are fixedly connected to rotating parts 6022, the two top rotating parts 6022 are fixedly connected to the second fixing plate 9, and the two bottom rotating parts 6022 are fixedly connected to the foot fixing sleeve 5, and the surfaces of the four connecting screws 6024 are threadedly connected to limiting nuts 6023.

[0054] Specifically, by rotating the connecting column 6021 to change the extension length of the connecting screw 6024, when the limit nut 6023 is turned in the opposite direction of the connecting column 6021, the restriction on the connecting screw 6024 is released. After the adjustment is completed, the limit nut 6023 is turned in the direction of the connecting column 6021 to fix the position of the connecting screw 6024 and the connecting column 6021, thereby adjusting and fixing the foot angle and solving the problem of the sole posture. The rotating part 6022 rotates along with the connecting screw 6024 when it is rotated and adjusted with the connecting column 6021, and can adapt to the angle change of the connecting screw 6024, so that the connection between the connecting screw 6024 and the second fixing plate 9 and the foot fixing sleeve 5 is always stable.

[0055] The first liner 1 and the second liner 13 are both made of medical silicone material, and the surfaces of the first liner 1 and the second liner 13 are both provided with ventilation holes, and the diameter of the ventilation holes is 2 mm.

[0056] Specifically, the medical silicone material has good biocompatibility, does not cause irritation or allergic reaction to human tissue, and is suitable for long-term contact with the skin, which makes the first lining 1 and the second lining 13 safer when in contact with the skin of the leg.

[0057] The first fixing plate 2 and the second fixing plate 9 are both made of carbon fiber composite material, and the thickness of the first fixing plate 2 and the second fixing plate 9 is 5 mm.

[0058] Specifically, the carbon fiber composite material has high strength and can provide a solid support force for the first fixing plate 2 and the second fixing plate 9. Even if the patient is subjected to external force impact when moving, it can effectively resist deformation and ensure stable fixation of the leg fracture site, making the first fixing plate 2 and the second fixing plate 9 very light. Compared with the metal fixing plate, it can greatly reduce the overall weight of the device and reduce the burden on the patient when wearing it, making it easier for the patient to move during the recovery period, which helps to improve the patient's use experience. At the same time, the carbon fiber composite material has good corrosion resistance and will not rust due to contact with sweat, body fluids, etc., thereby extending the service life of the first fixing plate 2 and the second fixing plate 9.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
