Description

Technical Field

[0001] This invention relates to the field of orthopedic devices, and particularly to an orthopedic repositioning and fixation orthopedic orthopedic device. Background Technology

[0002] In orthopedic clinical treatment, timely and accurate reduction and stable and reliable fixation are crucial for ensuring normal bone healing, preventing deformities, and maximizing the recovery of limb function in patients with upper limb fractures, joint dislocations, and severe soft tissue injuries. For a long time, splint-type external fixation devices have been widely used clinically, forming the basis of conservative treatment or postoperative auxiliary fixation. These devices typically consist of multiple independent, long, rigid or semi-rigid splints (such as plaster splints, polymer splints, metal or plastic splints). During use, the splints must be manually fitted by medical staff based on their experience, according to the anatomical shape of the injured limb, the direction of the fracture line, or the direction of dislocation.

[0003] In traditional procedures, medical staff first assess the degree of swelling, physiological curvature, and location of the injury in the affected limb, then select the appropriate number and size of splints. Subsequently, each splint is individually adjusted by hand through bending, shaping, or layering padding, attempting to make its contour conform as closely as possible to the irregular surface of the patient's limb. After adjustment, multiple splints are placed around the limb in a specific position, usually requiring one or more assistants to maintain the reduction and splint position. Finally, multiple layers of bandages, elastic bandages, or fixation straps are used to wrap and secure the affected area, achieving overall wrapping, pressure, and immobilization. This process is not only cumbersome and time-consuming, but maintaining the stability of the reduction posture and splint position is also quite challenging, especially in cases of acute injury accompanied by pain and swelling or poor patient cooperation.

[0004] Therefore, although splint-type fixation devices have a long history of clinical application in orthopedics and are relatively inexpensive, their complexity in operation, high dependence on the operator's skills, uncertainty of fixation effect, and inconvenience in adjustment have limited their widespread application in the pursuit of precise, standardized, and efficient modern orthopedic treatment. Summary of the Invention

[0005] The present invention aims to provide an orthopedic reduction and fixation orthopedic correction device that solves the problems of existing splint-type fixation devices that require high operator skills and are inconvenient to adjust.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: An orthopedic reduction and fixation orthopedic correction device, comprising:

[0007] Two housings, the two housings being arranged opposite to each other;

[0008] The two limiting frames are respectively disposed on the outer wall of the same side of the two shells;

[0009] Multiple first limiting teeth, which are distributed longitudinally within any one of the limiting frames;

[0010] A limiting rod, wherein the limiting rod is disposed within another limiting frame.

[0011] Multiple second limiting teeth are integrally formed on the free end of the limiting rod and engage with the first limiting teeth. The mutual engagement of the first and second limiting teeth can keep the relative positions of the two shells unchanged.

[0012] Multiple clamping plates are rotatably connected to two housings, and two opposing clamping plates are used to clamp the patient's limbs.

[0013] An angle adjustment component is disposed within two housings, and the angle adjustment component is capable of adjusting the rotation angle of the clamping piece according to the shape of the patient's limb.

[0014] Furthermore, the angle adjustment component includes:

[0015] Multiple fixed boxes are symmetrically fixedly arranged inside two shells, and the interior of each fixed box is filled with liquid.

[0016] Multiple fixing plates are arranged symmetrically inside the same fixing box, and each fixing plate has gaps between itself and the top and bottom sides of the fixing box.

[0017] Multiple first sealing plates and second sealing plates are slidably and sealingly connected between two fixed plates in the corresponding fixed box. The first sealing plate will float in the liquid, and the second sealing plate will sink to the bottom in the liquid.

[0018] Multiple push rods are fixedly connected to one side of the first sealing plate or the second sealing plate. The other end of each push rod passes through the fixed box and is rotatably connected to the clamping plate. The push rod is slidably sealed to the fixed box. All push rods in the two housings are arranged opposite each other.

[0019] Multiple third sealing plates, which can seal one side of the two fixing plates inside the fixing box;

[0020] Multiple drive components, each of which is capable of adjusting the position of the third sealing plate.

[0021] Furthermore, the drive assembly includes a push plate connected to all third sealing plates within the same housing. A return spring is connected between the push plate and the fixed box, which maintains an appropriate distance between the push plate and the fixed box. At this time, the third sealing plates do not seal one side of the two fixed plates inside the fixed box. A drive cam abuts against the outside of the push plate, and the drive cam is rotatably connected to the housing via a rotating shaft.

[0022] Furthermore, a spiral spring is connected between the rotating shaft and the housing. After the spiral spring is fully released, the drive cam can push the push plate and the third sealing plate towards the fixed box, and the third sealing plate can seal one side of the two fixed plates inside the fixed box.

[0023] Furthermore, a rotating handle located outside the housing is provided on one side of the rotating shaft.

[0024] Furthermore, each of the clamping pieces has a cushioning sponge on its inner side.

[0025] Compared with existing technologies, the beneficial effects of this solution are:

[0026] 1. This solution uses two opposing housings, along with limiting frames and limiting rods respectively mounted on the housings. The engagement of the first and second limiting teeth quickly and securely locks the relative positions of the two housings, replacing the cumbersome winding and binding process of traditional clamp devices and greatly simplifying the operation. This allows clinical medical staff to more conveniently and efficiently complete the overall positioning and closure of the device when performing external fixation, reducing reliance on operator experience and multiple-person assistance.

[0027] 2. This design incorporates multiple independently rotatable clamping plates, which, combined with internal angle adjustment components, can adaptively adjust their angles to conform to the irregular contours of the patient's limb surface. When the housing is closed onto the limb, the clamping plates contact the limb. Under the combined action of internal liquid pressure and the floating sealing plate, each push rod drives the clamping plates to rotate to varying degrees, thus achieving multi-point, multi-angle flexible contact with the limb surface. This structure significantly improves the anatomical fit of the device to the affected limb, enhances the comfort and stability of fixation, and avoids the problems of uneven pressure or inaccurate fixation points caused by inaccurate manual shaping in traditional splints.

[0028] 3. This design utilizes the interaction between the drive cam and the return spring to control the opening and closing of the third sealing plate. Initially, the return spring keeps the sealing plate open, allowing fluid to flow between the fixing plates and providing conditions for free adjustment of the clamping pieces. When the drive cam is rotated by turning the handle, pushing the push plate, the third sealing plate closes a specific chamber within the fixing box. At this point, the entire angle adjustment system is locked, and the positions of each clamping piece are fixed. This one-button locking mechanism ensures that the clamping posture is quickly and reliably maintained after the fit adjustment is completed, preventing displacement during subsequent use and enhancing the overall integrity and durability of the fixation. Simultaneously, the spiral spring extends the action time of the drive cam on the push plate, providing more operating time for the entire device to clamp and fix the patient's limb.

[0029] 4. The structural design of this solution combines flexibility with rigid fixation. The cushioning foam on the inner side of the clamping plate further increases patient comfort and reduces local pressure. Simultaneously, the engagement of the limiting teeth and the mechanical locking of the angle adjustment component provide dual fixation protection, ensuring continuous, stable, and uniform fixation support for the affected limb after fracture or joint dislocation reduction. This promotes bone healing and soft tissue recovery, reducing the risk of complications caused by improper fixation. Attached Figure Description

Detailed Implementation

[0035] The present invention will be further described in detail below through specific embodiments:

[0036] Example

[0037] like Figures 1 to 4 As shown, an orthopedic reduction and fixation orthopedic correction device includes:

[0038] Two housings 1 are arranged opposite each other, and the cross-sectional shape of each housing 1 is U-shaped.

[0039] Limiting frames 2 are respectively set on the outer walls of the front side of the two housings 1, and each limiting frame 2 is a square frame.

[0040] Multiple first limiting teeth 3 are longitudinally distributed within the lower limiting frame 2. Each first limiting tooth 3 is triangular, with the hypotenuse of each triangle facing the limiting rod 4.

[0041] The limiting rod 4 has a connecting plate 5 welded to its upper end. The connecting plate 5 is fixedly connected to the top of the limiting frame 2 located on the upper side. The limiting rod 4 itself has a certain elasticity, and the size of the limiting rod 4 is smaller than the size of the inner space of the limiting frame 2.

[0042] Multiple second limiting teeth 6 are integrally formed on the free end of the limiting rod 4, and all the second limiting teeth 6 are longitudinally spaced. Each second limiting tooth 6 is triangular, and the inclined surfaces of the first limiting tooth 3 and the second limiting tooth 6 are arranged opposite each other. The first limiting tooth 3 and the second limiting tooth 6 can use their inclined surfaces to push the limiting rod 4 to elastically deform and shift to the other side of the limiting frame 2. The two right-angled sides of the first limiting tooth 3 and the second limiting tooth 6 engage to achieve a one-way engagement connection. After the first limiting tooth 3 and the second limiting tooth 6 engage, the relative position of the two shells 1 remains unchanged. When it is necessary to separate the two shells 1, it is only necessary to push the limiting rod 4 away from the first limiting tooth 3. At this time, the first limiting tooth 3 loses its constraint on the second limiting tooth 6, so that the two can be easily separated.

[0043] Four clamping plates 7 are rotatably connected to two housings 1, with the two opposing clamping plates 7 used to clamp the patient's limb. Each clamping plate 7 has a cushioning sponge 8 on its inner side, which reduces local pressure and makes the clamping plate 7 clamp the patient's limb more securely.

[0044] An angle adjustment assembly is disposed within the two housings 1. This assembly can adjust the rotation angle of the clamping piece 7 according to the shape of the patient's limb. In this embodiment, the angle adjustment assembly includes:

[0045] Four fixed boxes 9 are symmetrically arranged inside two shells 1. Two fixing rods 10 are welded between one side of each fixed box 9 and the inner wall of the shell 1. Each fixed box 9 is filled with liquid, which is clean water in this embodiment.

[0046] Eight fixing plates 11 are arranged symmetrically in the middle of the same fixing box 9 in pairs, and gaps are left between each fixing plate 11 and the upper and lower side walls of the fixing box 9 to facilitate the flow of liquid.

[0047] Four first sealing plates 12 and four second sealing plates 13 are slidably and sealingly connected between two fixed plates 11 in the corresponding fixed box 9. The first sealing plates 12 are made of wood and will float in the liquid. The second sealing plates 13 are made of iron and will sink in the liquid.

[0048] Four push rods 14 are fixedly connected to one side of the first sealing plate 12 or the second sealing plate 13, respectively. The other end of each push rod 14 passes through the fixed box 9. The fixed box 9 has a first through hole that mates with the push rod 14, and the push rod 14 is slidably sealed to the corresponding first through hole. A pin 15 is provided at the end of each push rod 14 outside the fixed box 9. Both ends of the pin 15 are rotatably connected to a fixing plate 16 that is fixedly connected to the clamping plate 7. All the push rods 14 in the two housings 1 are arranged opposite each other.

[0049] Eight third sealing plates 17, each fixed box 9 has two spaced second through holes on one side, the second through holes are directly opposite the corresponding fixed plate 11, and the multiple third sealing plates 17 can seal one side of the two fixed plates 11 inside the fixed box 9.

[0050] Two drive components are provided, each capable of adjusting the position of the third sealing plate 17. In this embodiment, the drive components include two push plates 18, each push plate 18 connected to all the third sealing plates 17 within the same housing 1, and the push plate 18 located outside the fixed box 9. A third through hole is provided on the push plate 18 for the fixing rod 10 to pass through. Two symmetrically arranged return springs 19 are connected between each push plate 18 and the corresponding fixed box 9. The return springs 19 maintain an appropriate distance between the push plate 18 and the fixed box 9, ensuring that the third sealing plate 17 does not seal one side of the two fixed plates 11 within the fixed box 9. A drive cam 20 abuts against the outside of the push plate 18, and a rotating shaft 21 passes through the center of the drive cam 20, rotatably connecting the two side walls of the housing 1. A groove is also provided on the inner wall of the housing 1, and a spiral spring 22 connects the rotating shaft 21 to the groove. After the spiral spring 22 is fully released, the push plate 18 and the third sealing plate 17 can be pushed towards the fixed box 9 by the rotating shaft 21 and the drive cam 20, and the third sealing plate 17 can seal one side of the two fixed plates 11 inside the fixed box 9. The rotating shaft 21 is also provided with a rotating handle 23 located outside the housing 1, which facilitates the adjustment of the position of the drive cam 20.

[0051] The working process of this embodiment is as follows:

[0052] When not in use, the two housings 1 are in a separated state (i.e., the limiting rod 4 is not inserted into the limiting frame 2 on the other housing 1). Simultaneously, the angle adjustment components within each housing 1 are locked; that is, the drive cam 20 applies a pushing force to the push plate 18 under the action of the return spring 19, the third sealing plate 17 seals the gap between the fixing plate 11 and the fixing box 9, and the spiral spring 22 is not engaged. At this time, the first sealing plate 12 and the second sealing plate 13 within the fixing box 9 are stationary, and the push rod 14 and the connected clamping piece 7 are also in a locked state where they cannot rotate.

[0053] During the fixation procedure, medical staff first place the patient's repositioned limb (e.g., upper limb) onto the housing 1 containing the first sealing plate 12. Then, a limiting rod 4 from another housing 1 is passed through a limiting frame 2 on that housing 1. Under its own weight, the two housings 1 close around the limb. During this process, the limiting frames 2 and limiting rod 4 on the two housings 1 gradually approach each other. When the inclined surfaces of the first limiting tooth 3 and the second limiting tooth 6 come into contact, a force is generated that causes the elastic limiting rod 4 to deflect outwards. As the housings 1 continue to close, the limiting rod 4 springs back to its original position under its own elasticity, causing the second limiting tooth 6 to insert between two adjacent first limiting teeth 3. The right-angled edges of the first limiting teeth 3 and the second limiting tooth 6 engage with each other, thereby locking the two housings 1 in their current relative position. This achieves rapid and secure fixation of the device, replacing traditional strapping. While the two housings 1 are engaged, the drive cam 20 inside the two housings 1 is rotated by the handle and rotating shaft 21, causing the shorter diameter side to abut against the push plate 18. At this time, the push plate 18 moves towards the side of the original fixing box 9 under the action of the return spring 19, causing the third sealing plate 17 to open the closed space on one side of the fixing plate 11, releasing the locking effect on the clamping piece 7. Simultaneously, the spiral spring 22 rotates, which can drive the rotating shaft 21 to extend and return to its original position, allowing sufficient operation time for subsequent angle adjustment of the clamping piece 7 and enabling automatic locking.

[0054] As the upper shell 1 descends, the limb surface naturally comes into contact with the cushioning sponge 8 inside the multiple clamping plates 7, generating pressure. This pressure is transmitted through the clamping plates 7 to the push rod 14, which in turn pushes the first sealing plate 12 or the second sealing plate 13 inside the fixing box 9. Since the first sealing plate 12 has a density less than the liquid and tends to float, while the second sealing plate 13 has a density greater than the liquid and tends to sink, all the clamping plates 7 exert a positive compressive force on the limb. At this time, the irregularity of the limb's contour causes the clamping plates 7 at different positions to experience different pressures. This causes the first sealing plate 12 or the second sealing plate 13 in each fixing box 9 to move to different equilibrium positions in the liquid, and drives the corresponding clamping plates 7 to rotate at a corresponding angle through the push rod 14. Since the liquid can flow freely between the chambers inside the box, this adjustment process is dynamic and adaptive, ultimately allowing all the clamping plates 7 to flexibly rotate to the angle that best fits the contour of the limb surface, achieving multi-point, flexible, and personalized adaptation, and ensuring uniform pressure distribution.

[0055] After the fitting adjustment is completed, the rotating shaft 21 will drive the drive cam 20 to reset under the action of the spiral spring 22, thereby pushing the push plate 18 and the third sealing plate 17 back towards the corresponding fixed box 9. The third sealing plate 17 will seal one side of the fixed box 9, thereby blocking the flow of liquid on the upper and lower sides of the fixed plate 11. Since the liquid is almost incompressible, the volume of liquid in the fixed box 9 is locked, and the positions of the sealing plate and the push rod 14 are also fixed and cannot be moved. This achieves the relative fixation of the positions of the first sealing plate 12 and the second sealing plate 13. As a result, the rotation angle of all clamping pieces 7 is simultaneously and firmly locked, forming a rigid fixed structure.

[0056] When the treatment is over and the device needs to be removed, the two housings 1 can be easily separated and the entire device removed from the patient's limb by using a tool or manually moving the limiting rod 4 to disengage it from the first limiting tooth 3.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
