Description

Technical Field

[0001] This utility model relates to the field of orthopedic medical device technology, specifically to an orthopedic external fixation bracket. Background Technology

[0002] In orthopedic treatment, especially after fracture surgery or during limb external fixation, external fixation devices are often used to position and restrict the movement of the affected limb. Traditional external fixation devices typically use rigid plates combined with curved splints or straps to clamp and support the limb to prevent displacement or rotation.

[0003] However, existing rigid clamping structures typically use curved metal or high-strength engineering plastic sheets. While these materials provide sufficient fixing force, they also exert certain local pressure on the skin and soft tissues, causing discomfort, swelling, indentations, or even pressure injuries to patients when used for a long time. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an orthopedic external fixation bracket.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An orthopedic external fixator, comprising:

[0007] The support board is detachably installed on one side of the hospital bed, and its top has a support plate for supporting the patient's limbs;

[0008] Two symmetrically arranged arc-shaped clamping plates are set on the top of the aforementioned support plate. They have a central arc-shaped structure and two side plate-shaped structures. The arc-shaped structures of the two aforementioned arc-shaped clamping plates are fitted onto the sides of the patient's limb. Each of the two plate-shaped structures of the aforementioned arc-shaped clamping plates is fitted with a pressing rod threaded to the support plate. Initially, the arc-shaped structures of the two arc-shaped clamping plates fit against the patient's limb.

[0009] The extrusion member, connected to the aforementioned arc-shaped clamping plate, includes:

[0010] An air reservoir is located between two plate-like structures that are close to each other, consisting of two aforementioned arc-shaped clamping plates.

[0011] The compression airbag is located within the recess of the arc-shaped structure of the aforementioned arc-shaped clamping plate;

[0012] The conduit is connected at one end to the reservoir and at the other end to the compression bladder.

[0013] When the pressing lever is tightened, the arc-shaped structures of the two arc-shaped clamping plates bend in opposite directions, and the plate-like structures of the two arc-shaped clamping plates squeeze the air reservoir. When the gas in the air reservoir enters the squeeze air reservoir through the tube, the squeeze air reservoir fits the patient's limb.

[0014] Preferably, the aforementioned compression airbag is located at the symmetrical center of the concave arc structure of the arc-shaped clamping plate.

[0015] Preferably, when the pressing rod is tightened, the distance of relative displacement at the midpoint of the arc-shaped structure of the two arc-shaped clamping plates is less than the distance of relative displacement of the two compression airbags.

[0016] Preferably, the side of the pressing rod that is attached to the plate-like structure of the arc-shaped clamping plate is arc-shaped.

[0017] Preferably, a sealing plate is fixed on the aforementioned support plate to restrict the position of the air reservoir, and the sealing plate, together with the plate-like structure of the arc-shaped clamping plate, compresses the air reservoir.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By setting two arc-shaped clamping plates and their adjustable arc-shaped structure, the patient's limbs can be stably covered and positioned in the initial state. When the clamping plates are expanded outward by tightening the pressing rod, the air storage bag and the compression bag work together to automatically fit the flexible air bag while the bracket is deformed. This avoids the continuous pressure on soft tissues caused by traditional rigid structures and improves the comfort and safety of the fixation process.

[0020] 2. The mechanical motion of the clamping plate during deformation serves as the energy input source. Its plate-like structure compresses the air reservoir, which is then inflated via a conduit, achieving automatic, flexible fit. The entire process does not rely on an external air pump or manual inflation device. It features a simple structure, convenient control, higher efficiency, lower risk, and is easy to promote and use in clinical settings.

[0021] 3. By placing the compression airbag in the symmetrical center recess of the arc structure of the clamping plate and fixing the position of the airbag with the sealing plate, it can be ensured that the expansion direction of the airbag is stable after being compressed, and the gas distribution is more uniform and the fit is tighter.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0031] Example

[0032] like Figures 1-3 As shown, an orthopedic external fixation frame includes a support plate 1, two symmetrically arranged arc-shaped clamping plates 2, and a compression member. The support plate 1 is detachably mounted on one side of the hospital bed, and its top has a support plate 11 for supporting the patient's limb. The support plate 11 provides initial support and bolstering for the patient's limb.

[0033] In one embodiment, such as Figures 1-3 As shown, two symmetrically arranged arc-shaped clamping plates 2 are positioned on top of the support plate 11. Each plate has a central arc-shaped structure and two side plate-like structures. The arc-shaped structures of the two clamping plates 2 form a semi-enclosed shape, fitting around the patient's limbs and providing initial positioning. Each arc-shaped clamping plate 2 has two plate-like structures with threaded pressing rods 21 inserted into it, connected to the support plate 11. Initially, the arc-shaped structures of the two clamping plates 2 are in contact with the patient's limb. By tightening the pressing rods 21, the plate-like structures of the two arc-shaped clamping plates 2 can be pushed to move towards each other, simultaneously causing the arc-shaped structures of the two clamping plates 2 to open in opposite directions, thus gradually separating them from the patient's limb and creating a gap.

[0034] In one embodiment, such as Figures 2-3 As shown, the extrusion member is connected to the arc-shaped clamping plate 2 to provide a flexible covering structure during the deformation of the clamping plate. It includes:

[0035] The air storage bladder 31 is located between two plate-like structures of two arc-shaped clamping plates 2 that are close to each other;

[0036] The compression airbag 32 is located in the recess of the arc-shaped structure of the arc-shaped clamping plate 2;

[0037] The conduit 33 is connected at one end to the air reservoir 31 and at the other end to the compression air reservoir 32.

[0038] During the tightening of the pressing rod 21, the arc-shaped structures of the two arc-shaped clamping plates 2 bend in opposite directions, and the plate-like structures of the arc-shaped clamping plates 2 gradually move inward and squeeze the air reservoir 31. The gas in the air reservoir 31 is delivered to the compression air reservoir 32 through the conduit 33, causing the compression air reservoir 32 to gradually expand, thereby forming a flexible fit with the patient's limb, avoiding pressure on the limb from the rigid structure, and improving the comfort and safety of the stent.

[0039] In one embodiment, such as Figures 2-3 As shown, the compression airbag 32 is located at the concave symmetrical center of the arc-shaped structure of the arc-shaped clamping plate 2. This structural arrangement allows the compression airbag 32 to work from the part of the arc-shaped clamping plate 2 closest to the patient when it expands, uniformly covering the surface of the limb, effectively preventing local pressure caused by eccentric expansion, and enhancing the flexible wrapping effect of the stent.

[0040] In one embodiment, such as Figures 2-3 As shown, when the pressing rod 21 is tightened, the distance of relative displacement at the midpoint of the arc-shaped structure of the two arc-shaped clamping plates 2 is less than the distance of relative displacement of the two compression airbags 32. This structural relationship indicates that the deformation range of the arc-shaped clamping plate 2 is limited. It mainly achieves the restraining effect by compressing the air storage bag 31 and inflating the compression airbag 32, preventing excessive mechanical opening and closing from causing limb disturbance. At the same time, it makes the flexible fitting ability of the airbag more prominent, thereby realizing the design intention of controlling the retreat of the rigid structure and the active fitting of the flexible structure.

[0041] In one embodiment, such as Figures 2-3 As shown, the side of the pressing rod 21 that is attached to the plate-like structure of the arc-shaped clamping plate 2 is arc-shaped. This design can better fit the shape of the plate-like structure of the arc-shaped clamping plate 2. During the rotation and pushing process, the contact surface is subjected to uniform force, which is not easy to slip or local force concentration. This is conducive to improving the stability and controllability of the deformation of the clamping structure, while reducing wear.

[0042] In one embodiment, such as Figures 2-3As shown, a sealing plate 12 is fixed on the support plate 11 to restrict the position of the air storage bag 31. The sealing plate 12, together with the plate-like structure of the arc-shaped clamping plate 2, compresses the air storage bag 31. During the compression process of the plate-like structure, the sealing plate 12 can prevent the air storage bag 31 from undergoing lateral displacement or bulging deformation, improve the compression efficiency, and make the compression force more concentrated on the air storage bag 31, thereby improving the gas transmission efficiency and further ensuring the reliability of the expansion and fit of the compressed air bag 32.

[0043] To facilitate the restriction of the patient's limbs, the symmetrically arranged arc-shaped clamping plates 2 and the clamping components thereon can be arranged in two or three linear groups to better restrict the position of the patient's limbs.

[0044] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
