Description

Technical Field

[0001] This invention relates to the field of orthopedic splint technology, and in particular to an orthopedic splint installation and fastening device. Background Technology

[0002] In orthopedic clinics, fractures of the long bones of the limbs (including hairline fractures) typically require immediate three-stage treatment: reduction, fixation, and functional exercises. Splint-bandage systems remain one of the most widely used external fixation methods both domestically and internationally due to their ease of operation, low cost, and radiolucency.

[0003] For fractures around the elbow joint, studies have shown that the musculoskeletal system of the elbow begins to show collagen fiber disorder, synovial adhesions, and disuse atrophy of muscle fibers after 2-3 weeks of rest. After more than 4 weeks of inactivity, the risk of joint capsule contracture and fibrosis increases significantly, easily leading to permanent flexion contractures or limited extension. Once the early, controllable window of activity is missed, even if the fracture heals well, soft tissue adhesions may force a prolonged rehabilitation period.

[0004] However, existing orthopedic splint fastening devices mostly use a first and second cylinder that are fixed together to restrain the patient's upper arm and forearm to stabilize the elbow. In reality, this method only clamps and fixes the elbow; the device needs to be removed later for rehabilitation training. This method is not only cumbersome but also prone to secondary injury during rehabilitation due to uncontrollable elbow movement. Summary of the Invention

[0005] This invention proposes an orthopedic splint installation and fastening device to address the shortcomings of the prior art. This device can switch between two states: clamping and fixation, and active exercise. It solves the problem that existing splints cannot be used for exercise, which affects the patient's later recovery. At the same time, it controls the training range and avoids secondary injury.

[0006] The technical solution of the present invention is: an orthopedic splint installation and fastening device, comprising a first cylinder and a second cylinder, wherein two circular grooves are provided opposite to each other on the outer wall of the first cylinder, and each circular groove is provided with a mounting ring, wherein a plurality of first elastic elements are evenly distributed between the outer wall of the mounting ring and the inner wall of the circular groove, and two sliding grooves are provided opposite to each other on the outer wall of the second cylinder. The splint installation and fastening device further includes: Two hinged components are positioned opposite each other between the first cylinder and the second cylinder; The two sliders are slidably connected within the two grooves, respectively. Two pairs of stops are respectively disposed in the two slide grooves, with each pair of stops located on both sides of each slider, and a connection is provided between each of the two stops and the slider. Two connecting rods are respectively set on both sides of the first cylinder and the second cylinder. One end of each connecting rod is rotatably connected to the mounting ring through a connector, and the other end of the connecting rod is hinged to the slider. Two adjusting members are respectively connected to two pairs of stops, and the adjusting members are used to adjust the distance between the two stops.

[0007] In at least one embodiment of the present invention, the adjusting member includes a threaded rod and an adjusting knob. Each of the stops is provided with a threaded hole. Two threaded rods are arranged opposite to each other on the outer wall of the second cylinder. The threaded rods are rotatably connected to the side of the slide groove. The threaded rods pass through the two threaded holes and are threadedly connected to the threaded holes. The threads on the threaded rods that are connected to the two stops have opposite directions of rotation. An adjusting knob is provided at the end of the threaded rod.

[0008] In at least one embodiment of the present invention, a pull ring is provided at the bottom of the second cylinder, and two pull rods are hinged to the bottom of the second cylinder. Each of the two pull rods is hinged to a support rod that is hinged to the slider, and a connecting rod is provided between the two pull rods.

[0009] In at least one embodiment of the present invention, each of the hinge components includes a fixed ring, a connecting ring, and a connecting post. The connecting ring is fitted inside the fixed ring, and a plurality of third elastic elements are evenly distributed between the connecting ring and the fixed ring. The connecting post is rotatably connected to the connecting ring, and the connecting post and the fixed ring are respectively connected to the first cylinder and the second cylinder.

[0010] In at least one embodiment of the present invention, the first cylinder and the second cylinder are both spliced ​​together by two arc-shaped plates, the two arc-shaped plates on the first cylinder and the second cylinder are hinged together, and the two arc-shaped plates on the first cylinder and the second cylinder are connected to each other by locking members.

[0011] In at least one embodiment of the present invention, each of the two arc-shaped plates on the first cylinder and the second cylinder is connected to a fixing plate by a fourth elastic element. The fixing plate has an arc-shaped cross section and each fixing plate is provided with an air hole.

[0012] In at least one embodiment of the present invention, the connectors on both connecting rods are detachably connected to the mounting ring.

[0013] In at least one embodiment of the present invention, the pull rod and the support rod are detachably connected to the second cylinder and the slider, respectively, and the two pull rods are provided with a plurality of through holes facing each other, through which the connecting rod passes. In at least one embodiment of the present invention, two arc-shaped plates of the first cylinder and the second cylinder are provided with connecting ears opposite each other, each connecting ear is provided with a through hole, and the locking member is a fastening bolt passing through the opposite connecting ears.

[0014] In at least one embodiment of the present invention, each of the fixing pieces is provided with a breathable pad layer on its inner wall, and the bolt of the locking member is a screw bolt.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The orthopedic splint installation and fastening device proposed in this invention fixes the patient's upper arm and forearm to the first and second cylinders respectively in the early stage of treatment. After fixation, the distance between the two stops is adjusted by the adjusting component to compress the spring between the stop and the slider, thereby locking the position of the slider and ultimately fixing the first and second cylinders. As the patient's elbow gradually recovers, when the patient needs to perform rehabilitation training, the distance between the two stops is adjusted by the adjusting component to reserve space for the slider to move, allowing the patient to perform active elbow movement training. During the active training, the springs on both sides of the slider cushion the patient's movement. Compared with the prior art, this device can switch between clamping fixation and active exercise without removing the device, avoiding atrophy of the fascia on the inner side of the elbow, which could lead to the inability to move the elbow later, thus ensuring the patient's post-injury recovery. Furthermore, during rehabilitation training, the distance between the two stops can be gradually increased or decreased as the patient's elbow recovers, preventing the slider from being completely unrestricted and causing excessive movement that could lead to secondary injury.

[0016] 2. The orthopedic splint installation and fastening device proposed in this invention allows the user to gradually squeeze the pull ring and connecting rod by hand when the patient is unable to perform active training due to pain in the affected area. This causes the two support rods to push the slider to move, thereby achieving passive training of the patient's elbow. This prevents the patient from missing the recovery period due to pain and difficulty in training. During the passive training process with the other hand, the patient can better control the range of motion and intensity of the injured elbow, which helps the patient to carry out recovery training that is more adapted to their own body.

[0026] Combination Figures 1 to 5 As shown, an orthopedic splint mounting and fastening device includes a first cylinder 1 and a second cylinder 2. The outer wall of the first cylinder 1 has two opposing circular grooves 11, each groove 11 having a mounting ring 111. Multiple first elastic elements are evenly distributed between the outer wall of the mounting ring 111 and the inner wall of the circular groove 11. The outer wall of the second cylinder 2 has two opposing sliding grooves 21. The splint mounting and fastening device also includes: Two hinges 3 are disposed opposite to each other between the first cylinder 1 and the second cylinder 2. Both hinges 3 are connected to the first cylinder 1 and the second cylinder 2 respectively to realize the bending movement between the first cylinder 1 and the second cylinder 2.

[0027] The two sliders 4 are slidably connected in the two grooves 21 respectively. Specifically, both grooves 21 can be T-shaped grooves, and the sliders 4 are T-shaped blocks that are adapted to the T-shaped grooves.

[0028] Two pairs of stop blocks 5 are respectively set in two slide grooves 21. Each pair of stop blocks 5 is located on both sides of each slider 4. A spring connected to the stop block 5 is provided between each stop block 5 and the slider 4.

[0029] Two connecting rods 6 are respectively set on both sides of the first cylinder 1 and the second cylinder 2. One end of each connecting rod 6 is rotatably connected to the mounting ring 111 through a connector, and the other end of the connecting rod 6 is hinged to the slider 4.

[0030] Two adjusting components 7 are connected to two pairs of stop blocks 5 respectively. The adjusting components 7 are used to adjust the distance between the two stop blocks 5 so as to adjust the movement space of the slider 4.

[0031] In use, the patient's upper arm and forearm are fixed to the first cylinder 1 and the second cylinder 2 respectively. After fixation, the distance between the two stops 5 is adjusted by the adjusting component 7, so that the spring between the stop 5 and the slider 4 is compressed, thereby locking the position of the slider 4, and finally fixing the first cylinder 1 and the second cylinder 2. When the patient needs to perform rehabilitation training, the distance between the two stops 5 is adjusted by the adjusting component 7, thereby reserving space for the slider 4 to perform active elbow movement training. During the active training, the springs on both sides of the slider 4 can cushion the patient's movement. The device can switch between clamping and fixation and active exercise, avoiding atrophy of the fascia on the inner side of the elbow, which could lead to the inability to move the elbow later, thus ensuring the patient's post-injury recovery. Furthermore, during rehabilitation training, the distance between the two stops 5 can be gradually increased or decreased as the patient's elbow recovers, preventing the movement of both sides of the slider 4 from being completely unrestricted and causing excessive movement that could lead to secondary injury.

[0032] As an alternative embodiment, the bottom of the second cylinder 2 is provided with a pull ring 22, and two pull rods 23 are hinged to the bottom of the second cylinder 2. Each of the two pull rods 23 is hinged with a support rod 231 that is hinged to the slider 4. A connecting rod 232 is provided between the two pull rods 23. In the early stage of the patient's activity training, the user can gradually squeeze the pull ring 22 and the connecting rod 232 by holding them, so that the two support rods 231 can push the slider 4 to move, thereby realizing the passive training of the patient's elbow. This avoids the patient missing the recovery period due to pain and difficulty in training. During the passive training with the other hand, the patient can better control the range of motion and intensity of the injured elbow, which helps the patient to carry out recovery training that is more adapted to himself.

[0033] As an alternative embodiment, the adjusting component 7 includes a threaded rod 71 and an adjusting knob 72. Each stop block 5 has a threaded hole. Two threaded rods 71 ​​are arranged opposite each other on the outer wall of the second cylinder 2. The threaded rods 71 ​​are rotatably connected to the side of the slide groove 21. The threaded rods 71 ​​pass through the two threaded holes and are threadedly connected to the threaded holes. The threads on the threaded rods 71 ​​that connect to the two stop blocks 5 have opposite directions of rotation. The end of the threaded rod 71 is provided with an adjusting knob 72. When the second stop block 5 needs to be adjusted, the adjusting knob 72 is turned to make the adjusting knob 72 drive the threaded rod 71 to rotate. Since the threads on the two parts of the threaded rod 71 have opposite directions of rotation, the two stop blocks 5 can move toward the opposite or opposite side during the rotation of the threaded rod 71.

[0034] As an alternative embodiment, each hinge component 3 includes a fixed ring 31, a connecting ring 32, and a connecting post 33. The connecting ring 32 is fitted inside the fixed ring 31, and multiple third elastic elements are evenly distributed between the connecting ring 32 and the fixed ring 31. The connecting post 33 is rotatably connected to the connecting ring 32, and the connecting post 33 and the fixed ring 31 are respectively connected to the first cylinder 1 and the second cylinder 2. The hinge component 3 used in this invention takes into account the dynamic changes in the position of the joint center during the patient's elbow flexion and extension. By designing the connecting ring 32 and the fixed ring 31, as well as the multiple third elastic elements distributed between the connecting ring 32 and the fixed ring 31, flexible adjustment of the joint center position at different flexion and extension positions, as well as flexible adjustment of the support force at different flexion and extension positions, is achieved, making existing knee joint rehabilitation devices better meet the functional requirements of patients during use.

[0035] As an alternative embodiment, both the first cylinder 1 and the second cylinder 2 are spliced ​​together from two arc-shaped plates. The two arc-shaped plates on the first cylinder 1 and the second cylinder 2 are hinged together. Locking members 12 are connected to each other on the two arc-shaped plates of the first cylinder 1 and the second cylinder 2. The first cylinder 1 and the second cylinder 2, which are composed of the locking members 12 and the two arc-shaped plates, can be quickly disassembled and installed at the patient's elbow.

[0036] As an alternative embodiment, each of the two arc-shaped plates on the first cylinder 1 and the second cylinder 2 is connected to a fixing plate 13 by a fourth elastic element. The fixing plate 13 has an arc-shaped cross-section. The fourth elastic element and the fixing plate 13 can adjust the clamping force on the patient's upper arm and forearm with the cooperation of the locking element 12. In the later stage of the patient's recovery, it can not only provide stable protection, but also improve the patient's wearing comfort by reducing the clamping force, which helps the patient recover better. Each fixing plate 13 is provided with an air hole for ventilation when fixing the patient.

[0037] As an alternative embodiment, the connectors on both links 6 are detachably connected to the mounting ring 111. Specifically, the connectors on the links 6 are inserted into the mounting ring 111. When using the device, if the patient's recovery is good, the connectors can be removed to allow the patient to perform more extensive trial exercises.

[0038] As an alternative embodiment, the pull rod 23 and the support rod 231 are detachably connected to the second cylinder 2 and the slider 4, respectively. The two pull rods 23 are provided with multiple through holes opposite to each other, and the connecting rod 232 passes through a pair of opposite through holes. During the passive training process of the patient using this device, the connecting rod 232 can be passed through any pair of through holes according to the amplitude of the passive training.

[0039] As an alternative embodiment, the first cylinder 1 and the second cylinder 2 are provided with connecting ears 14 opposite each other on their two arc-shaped plates. Each connecting ear 14 is provided with a through hole. The locking member 12 is a fastening bolt that passes through the through hole on the opposite connecting ear 14. The setting of the locking member 12 ensures that the arc-shaped plates of the first cylinder 1 and the second cylinder 2 are stably connected, thereby enabling the device to be stably fixed on the patient's arm.

[0040] As an alternative embodiment, each fixing piece 13 has an air-permeable pad on its inner wall. The air-permeable pad improves the comfort of using the device and ensures that the patient can recover healthily. The bolts of the locking piece 12 are spur bolts. The spur bolts make it easy for the patient to make quick manual adjustments to the device as needed.

[0041] The working principle and usage method of this embodiment: This invention provides an orthopedic splint installation and fastening device. In the early stages of patient treatment, the patient's upper arm and forearm are fixed to the first cylinder 1 and the second cylinder 2, respectively. At the same time, by turning the adjusting knob 72, the two stops 5 are moved to opposite sides, thereby locking the position of the slider 4, thus ensuring that the first cylinder 1 and the second cylinder 2 are in a fixed state and stably fixing the patient's elbow.

[0042] As the patient's elbow gradually recovers, when the patient needs to perform rehabilitation training, the adjustment knob 72 is turned again to move the two blocks 5 toward opposite sides, thereby reserving space for the slider 4 to move. This allows the patient to perform active elbow movement training, preventing atrophy of the fascia on the inner side of the elbow, which could lead to the inability to move the elbow later. During the patient's rehabilitation training, the distance between the two blocks 5 gradually increases as the patient's elbow recovers, preventing excessive movement and secondary injury caused by completely unrestricted movement space.

[0043] Simultaneously, in the initial stages of activity training, patients may find it difficult to perform active training due to pain in the affected area, easily missing the recovery period. At this time, the user can gradually squeeze the pull ring 22 and connecting rod 232 by hand, causing the two support rods 231 to push the slider 4, thus achieving passive training of the patient's elbow. This prevents patients from missing the recovery period due to pain hindering training. During passive training with the other hand, patients can better control the range and intensity of movement of their injured elbow, helping them to perform recovery training more suited to their own body. In summary, by limiting the range of motion and combining active and passive training, better and faster recovery is ensured for patients.

[0044] The above embodiments are merely specific implementations of the present invention, used to illustrate the technical solutions of the present invention, and not to limit them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed in the present invention, or make equivalent substitutions for some of the technical features; and these modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions implemented in the present invention, and should all be covered within the protection scope of the present invention.
