Description

Technical Field

[0001] This utility model relates to the field of splint technology, and in particular to an orthopedic splint with adjustable length. Background Technology

[0002] Orthopedic splints are commonly used external fixation devices for treating limb fractures. Their main function is to support and fix the fracture site, maintain the position of the fracture after reduction, prevent displacement of the fracture ends, and create a stable environment for fracture healing.

[0003] Currently, most orthopedic splints used in clinical practice are fixed-length structures, and their specifications are usually designed according to common limb lengths. However, due to individual differences in limb length and fracture location among different patients, fixed-length splints are often difficult to fit precisely. If the splint is too short, it cannot effectively cover the joints at both ends of the fracture site, making reliable fixation difficult; if the splint is too long, it may cause pressure on other parts of the limb, affecting blood circulation or causing patient discomfort. Utility Model Content

[0004] The technical problem this invention aims to solve is that, due to individual differences in limb length and fracture location among different patients, fixed-length splints are often difficult to fit precisely.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: an adjustable-length orthopedic splint, including a central guard plate, with extension guard plates provided at both ends of the central guard plate, wherein the extension guard plates can slide at both ends of the central guard plate to adjust the length of the orthopedic splint; positioning components are provided on the extension guard plates and the central guard plate, the positioning components including a first card seat, a second card seat, and a positioning rod, the first card seat and the second card seat having insertion holes, the first card seat being fixed to the surface of the central guard plate, the second card seat being fixed to the surface of the extension guard plate, wherein the number of the first card seat and the second card seat is more than two, and they are arranged along the length direction of the orthopedic splint, the positioning rod having vertical bends on both sides, the positioning rod being U-shaped, the bends on both sides of the positioning rod being inserted into the insertion holes of the first card seat and the second card seat respectively, for positioning the extension guard plate, and at least one side of the bend of the positioning rod having an interference fit with the insertion hole.

[0006] The effect achieved by the above components is as follows: when a limb fracture occurs, the two extension plates are first adjusted to slide on the surface of the central plate to adjust the length of the orthopedic splint. Then, the position of the extension plates is positioned using the positioning component. Finally, a bandage is wrapped between the orthopedic splint and the limb fracture site to achieve fixation and support. Since the extension plates can slide at both ends of the central plate, they can be adapted to different users.

[0007] In some embodiments, optionally, in the first and second card holders, there are two or more card holders arranged along the length of the orthopedic splint as the first card holder, and there are two positioning rods. The first card holder has a second card holder on both sides. The inner bent portions of the two positioning rods are inserted into the insertion hole of the same first card holder, and the outer bent portions of the two positioning rods are respectively inserted into the second card holders on both sides of the first card holder.

[0008] In some embodiments, optionally, the inner bent portion of the positioning rod has a groove, and the grooves on the inner bent portions of two positioning rods inserted into the same first card slot are joined together to form a pin hole, and a matching pin is inserted into the pin hole to make the inner bent portions of the two positioning rods interference fit with the socket.

[0009] The effect achieved by the above-mentioned components is that when the pin is inserted into the pin hole, the two bent parts can expand to achieve an interference fit, and the operation of achieving the interference fit is convenient.

[0010] In some embodiments, optionally, the pin hole is a polygonal pin hole, and the pin is a polygonal pin that matches the polygonal pin hole.

[0011] The effect achieved by the above components is that, compared to relying solely on the frictional force of the interference fit to constrain the rotational tendency between the bent parts of the positioning rod and within the insertion hole, designing the pin hole and pin as polygonal can further constrain the rotational tendency between the bent parts of the positioning rod and within the insertion hole, thus achieving a better positioning effect for the extension guard plate.

[0012] In some embodiments, the two ends of the central guard plate protrude outwards, a track plate is provided on the protruding surface of the central guard plate, and a groove is provided on the surface of the extended guard plate, so that the extended guard plate can slide on the surface of the track plate on the surface of the central guard plate by means of the groove.

[0013] In some embodiments, optionally, a limiting piece is fixedly connected to the surface of the extension guard, a bandage passes through the inside of the limiting piece, and a cotton pad is fixedly connected to the inside of the extension guard.

[0014] The effects achieved by the above components are as follows: the limiting plate can limit the position of the strap to prevent the strap from slipping; and by padding the extension plate and the limb shaft with cotton balls, the extension plate can be prevented from directly contacting the limb shaft.

[0015] The beneficial effects of this utility model are: when encountering a limb fracture, first adjust the two extension plates to slide on the surface of the central plate to adjust the length of the splint, then use the positioning component to position the extension plates, and then use a bandage to wrap around the outside of the orthopedic splint to fix and support the limb fracture site. Since the extension plates can slide at both ends of the central plate, they can be adapted to different users. Attached Figure Description

[0024] like Figures 1-4As shown, an adjustable-length orthopedic splint includes a central guard plate 2, with extension guard plates 1 at both ends of the central guard plate 2. The extension guard plates 1 can slide at both ends of the central guard plate 2 to adjust the length of the orthopedic splint. Positioning components are provided on the extension guard plates 1 and the central guard plate 2. The positioning components include a first locking seat 7, a second locking seat 8, and a positioning rod 9. The first locking seat 7 and the second locking seat 8 have insertion holes. The first locking seat 7 is fixed to the surface of the central guard plate 2, and the second locking seat 8 is fixed to the surface of the extension guard plate 1. In the first locking seat 7 and the second locking seat 8, there are more than two locking seats, which are evenly arranged along the length direction of the orthopedic splint. The positioning rod 9 has vertical bends on both sides and is U-shaped. The bends on both sides of the positioning rod 9 are respectively inserted into the insertion holes of the first locking seat 7 and the second locking seat 8 to position the extension guard plate 1. At least one side of the bend of the positioning rod 9 is interference-fitted with the insertion hole.

[0025] The two ends of the central guard plate 2 protrude outwards, and the protruding surface of the central guard plate 2 is provided with a track plate 3. The surface of the extension guard plate 1 is provided with a sliding groove 4. The extension guard plate 1 slides on the surface of the track plate 3 of the central guard plate 2 by means of the sliding groove 4, thereby adjusting the overall length of the orthopedic splint.

[0026] In this embodiment, specifically, in the first card holder 7 and the second card holder 8, there are two or more card holders arranged along the length of the orthopedic splint, which constitute the first card holder 7. There are two positioning rods 9. The first card holder 7 has a second card holder 8 on both sides. The inner bent parts of the two positioning rods 9 are inserted into the same insertion hole of the first card holder 7, and the outer bent parts of the two positioning rods 9 are respectively inserted into the second card holders 8 on both sides of the first card holder 7.

[0027] The inner bent portion of the positioning rod 9 has a groove. The grooves on the inner bent portions of the two positioning rods 9 inserted into the same first card holder 7 are combined to form a pin hole 92. A matching pin 91 is inserted into the pin hole 92 to make the inner bent portions of the two positioning rods 9 interfere with the insertion hole.

[0028] The pin hole 92 is a polygonal pin hole 92, and the pin 91 is a polygonal pin 91 that matches the polygonal pin hole 92.

[0029] A limiting piece 6 is fixedly connected to the surface of the extension guard plate 1, and a bandage 5 passes through the inside of the limiting piece 6. A cotton pad 10 is fixedly connected inside the extension guard plate 1.

[0030] Working principle: The protruding parts at both ends of the central guard plate 2 are provided with track plates 3, and the surface of the extension guard plate 1 is provided with grooves 4. The extension guard plate 1 can slide along the track plate 3 through the grooves 4, thereby lengthening or shortening the overall length of the orthopedic splint until it fits the joint spacing at both ends of the patient's fracture site.

[0031] Positioning and Fixing: After adjustment, the length is locked by the positioning component. When positioning the extension guard plate 1 by the positioning rod 9, first insert the outer bent part of the first positioning rod 9 into the insertion hole of the second card seat 8 without interference, then insert the inner bent part of the first positioning rod 9 into the insertion hole of the first card seat 7, then insert the outer bent part of the second positioning rod 9 into the insertion hole of the second card seat 8 on the other side of the extension guard plate 1 without interference, and insert the inner bent part of the second positioning rod 9 into the insertion hole of the first card seat 7. Finally, insert the pin 91 into the pin hole 92 so that the inner bent parts of the two positioning rods 9 are interference-fitted with the insertion holes.

[0032] Support and cushioning: A cotton pad 10 is fixed to the inside of the extension plate 1. When in use, a cotton ball is placed between the extension plate 1 and the limb to avoid the orthopedic splint directly compressing the skin. When in use, three sets of orthopedic splints can be set up and placed around the surface of the limb shaft. Then, the bandage 5 passing through the limiting piece 6 is wrapped around the outside of the orthopedic splint to clamp the three sets of orthopedic splints on the surface of the limb shaft, forming stable support for both ends of the fracture.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
