Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a torticollis teaching device. Background Technology

[0002] Torticollis, commonly known as "wry neck," is mainly related to congenital developmental abnormalities, poor posture, and muscle or nerve damage. It manifests as a tilting or twisting of the neck to one side, possibly accompanied by limited mobility and pain. Congenital factors are generally divided into two categories: muscle developmental abnormalities and skeletal developmental abnormalities. Muscle developmental abnormalities mainly manifest as fibrosis of the sternocleidomastoid muscle. Intrauterine compression during fetal development (such as malposition of the fetus) or birth injuries during delivery (such as breech presentation or forceps delivery) can lead to ischemia, hemorrhage, or contracture of one side of the sternocleidomastoid muscle, forming a fibrotic mass that pulls the head to the affected side. The effects of this factor require early intervention and treatment. Improvement can be achieved through postural adjustments (alternating breastfeeding positions), traction massage (gently stretching the muscles on the affected side), and strengthening head-lifting exercises. Intervention should begin within 3-6 months after birth to prevent deformities.

[0003] The examination and diagnosis of torticollis in infancy is particularly important, and the intervention methods and techniques are equally crucial. It is necessary to assess the strength of the traction massage, the range of motion of the cervical spine, and the angle of rotation based on the specific condition of the torticollis. However, currently, there are no facilities available for advance training and simulation based on the specific condition of torticollis, preventing medical staff from fully understanding and controlling the massage strength, rotation angle, and precautions for the cervical spine. Therefore, directly intervening in infants without a clear understanding can easily cause harm due to repeated adjustments to position, strength, and other treatment methods. Because infants are fragile, blind intervention without a precise treatment plan is unacceptable; otherwise, constant adjustments to the method and strength during the intervention process can cause further harm. Summary of the Invention

[0004] Based on this, this application provides a torticollis teaching device to solve the technical problem that there is no existing facility capable of simulating cervical spine deviation so that medical staff can train in advance and control the intensity and angle of massage during treatment.

[0005] The technical solution to the above-mentioned technical problems in this application is as follows:

[0006] A torticollis teaching device, comprising:

[0007] Cervical spine component, used to simulate the bending posture of the cervical spine;

[0008] A bending assembly, wherein the cervical spine assembly is sleeved on the bending assembly, and the bending assembly can cause the cervical spine assembly to bend;

[0009] A steering assembly, wherein the bending assembly is disposed on the steering assembly and is used for the bending assembly to rotate in the horizontal direction;

[0010] A muscle group component, connected to the bending component, is used to simulate the bending posture of the muscles surrounding the cervical spine after cervical flexion.

[0011] Preferably, it further includes a resistance component, which is sleeved on the bending component and the cervical spine component is sleeved on the resistance component. The resistance component is in frictional contact with the steering component. When the bending component bends, it can cause the resistance component to tilt, thereby increasing the friction between the resistance component and the steering component in the bending direction.

[0012] Preferably, the bending assembly includes a base post and a bending rod connected to the upper end of the base post and capable of bending, the resistance assembly is sleeved on the bending rod, and the base post is connected to the steering assembly.

[0013] Preferably, the resistance component includes an elastic sleeve and a retainer at the top of the elastic sleeve, the cervical spine component is sleeved on the outside of the elastic sleeve, and the retainer is sleeved on the bending rod.

[0014] Preferably, the cervical spine assembly includes several bone models and a pressure head that can be inserted into a sleeve. The several bone models are sequentially fitted onto the elastic sleeve from top to bottom, and a cervical intervertebral disc model is provided between every two adjacent bone models.

[0015] Preferably, the steering assembly includes a housing and a base fastened to the lower end of the housing. A bearing is connected to the inner wall of the housing, a base is connected to the inner ring of the bearing, and a rubber sleeve is provided between the inner ring of the bearing and the outer wall of the base.

[0016] Preferably, the resistance component further includes a disc connected to the lower end of the elastic sleeve, and a rubber pad is provided on the lower end surface of the disc, the rubber pad making frictional contact with the upper surface of the outer shell.

[0017] Preferably, the muscle group assembly includes a connecting seat and a connecting plate. The connecting plate is detachably connected to the disc, and the connecting seat is detachably connected to the pressure head. A longus colli muscle model is provided on the rear side between the connecting seat and the connecting plate, and sternocleidomastoid muscle models are provided on both sides between the connecting seat and the connecting plate.

[0018] Preferably, it further includes a skin component that wraps around the outside of the muscle group component to cover the muscle group component and the cervical spine component.

[0019] Preferably, the skin component includes an elastic sheath that wraps around the outside of the muscle group component. The elastic sheath is broken vertically at a certain position, and a connector is provided at the break position to connect the broken positions.

[0020] Compared with the prior art, this application has at least the following advantages:

[0021] This application provides a torticollis teaching device. A cervical spine component is fitted onto a bending component, which is then connected to a steering component. A muscle group component is connected to the outside of the bending component. The bending component is then manipulated to make its bending shape and posture closely resemble a diagnosed torticollis condition (such as torticollis in infants). As the bending component bends, it causes corresponding changes in the cervical spine component fitted onto it. This allows the cervical spine component to simulate the skeletal posture after torticollis develops, while the bending component causes corresponding deformation in the muscle group component, thus simulating the muscle changes after torticollis develops. This device can simulate an actual torticollis condition. Medical staff can understand the condition of torticollis by observing the simulated skeletal and muscle postures. They can also touch and feel the elasticity of the simulated muscle changes by touching the muscle group components, and conduct training in advance, selecting appropriate strength and angle for massage training and teaching. This allows medical staff to conduct simulated training and teaching after determining the condition of torticollis in infants and young children. It enables medical staff to understand the skeletal and muscular condition after the onset of torticollis and to train appropriate massage strength, techniques, and angles, thereby avoiding blind treatment without understanding the specific situation of the infant's torticollis.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] Please refer to Figures 1 to 9 In one specific embodiment of this application,

[0036] A torticollis teaching device, comprising:

[0037] Cervical spine component, used to simulate the bending posture of the cervical spine;

[0038] A bending assembly, wherein the cervical spine assembly is sleeved on the bending assembly, and the bending assembly can cause the cervical spine assembly to bend;

[0039] A steering assembly, wherein the bending assembly is disposed on the steering assembly and is used for the bending assembly to rotate in the horizontal direction;

[0040] A muscle group component, connected to the bending component, is used to simulate the bending posture of the muscles surrounding the cervical spine after cervical flexion.

[0041] Among them, the cervical spine component can be a skeletal model used to simulate the cervical spine; the bending component can be a metal rod that can bend on its own or a device that can deform; the steering component can be a rotating shaft or a rotating disk; the muscle group component can be an elastic component that simulates a muscle group or elastic muscle fibers made of rubber or silicone.

[0042] In practical use, the cervical spine component is fitted onto the bending component, which is then connected to the steering component. The muscle group component is then connected to the outside of the bending component. Medical staff set up the steering component on a workbench (table or other flat surface) and then bend the bending component to make its bending shape and posture as close as possible to the condition of torticollis (diagnosed torticollis posture in infants and young children). During this process, as the bending component bends, it can cause the cervical spine component fitted onto it to change accordingly. The cervical spine component can simulate the skeletal posture after torticollis. At the same time, the bending component can cause the muscle group component to deform accordingly, thereby simulating the muscle changes after torticollis. At this time, the bending shape and posture of the bending component remain unchanged, thus simulating the actual torticollis condition. Medical staff can understand the condition of torticollis by observing the simulated skeletal and muscle postures. They can then touch and feel the elasticity of the muscles simulated by the muscle group component to conduct training in advance, choosing appropriate strength and angle for massage training. The steering component can also be used to rotate the bending component, cervical spine component, and muscle group component, making it easy to adjust the observation and training angles.

[0043] It can also enable medical staff to use torticollis teaching devices to teach other personnel, such as guardians of infants and other medical staff, so that guardians and other medical staff can quickly learn relevant skills so that they can accurately grasp the situation when treating infants.

[0044] The above methods enable medical staff to conduct simulated training using a torticollis teaching device after diagnosing a torticollis condition in infants. This allows them to understand the condition of the bones and muscles involved in the torticollis beforehand, and to train appropriate massage strength, techniques, and angles. This avoids blindly treating infants without understanding the specifics of their torticollis, which could lead to harm due to incorrect massage strength, angle, or direction. Through simulation, advance training, and teaching, medical staff can anticipate and understand the actual treatment process for infants, minimizing errors or potential problems during actual operation.

[0045] During the actual examination of infants and young children with torticollis, it is found that the curvature of the cervical spine caused by torticollis leads to a shift in the center of gravity of the cervical spine. The weight of the head applied to the curved cervical spine increases the amount of the shift in the center of gravity and the pressure exerted by the overall weight on the direction of the cervical spine's curvature. Therefore, excessive local pressure caused by the shift in the center of gravity after torticollis can affect the rotation of the cervical spine. Thus, it is necessary to train and understand in advance the limitations and effects on rotation.

[0046] Therefore, the torticollis teaching device in this application further includes a resistance component, which is sleeved on the bending component, the cervical spine component is sleeved on the resistance component, the resistance component is in frictional contact with the steering component, and when the bending component bends, it can cause the resistance component to tilt, thereby increasing the frictional force between the resistance component and the steering component in the bending direction.

[0047] The resistance component can be a friction pad, which is set on the bending component. When the bending component bends, the resistance component can tilt according to the bending direction of the bending component, so that the force of the resistance component contacting the steering component in the bending direction increases. As the center of gravity of the bending component shifts after bending, the friction between the resistance component and the steering component increases. Thus, when the bending component rotates on the steering component, it drives the resistance component to rub against the steering component. The increased friction increases the resistance and difficulty of the bending component's rotation.

[0048] The above method can simulate the effect of cervical spine center of gravity shift on cervical spine rotation based on the cervical spine curvature. Therefore, when medical staff are trained in advance, they can understand the treatment and angle of turning according to different curvature states, and can carry out corresponding turning treatment according to different degrees of cervical dysplasia in infants and young children.

[0049] Specifically, an embodiment of the bending component in the above process is provided:

[0050] The bending assembly includes a base post 101 and a bending rod 103 connected to the upper end of the base post 101 and capable of bending. The resistance assembly is sleeved on the bending rod 103, and the base post 101 is connected to the steering assembly.

[0051] The bending rod 103 is made of a malleable material that can bend in any direction and maintain its position, such as a snake-shaped bracket, a flexible arm, or an octopus bracket. During use, the base column 101 is rotatably connected to the steering assembly via bearings, allowing the base column 101 to rotate on the steering assembly. Then, by holding the bending rod 103, it can be bent into a tilted neck posture, simulating the skeletal posture of a tilted neck.

[0052] By using the above methods, we can understand the skeletal changes after developing hemicervical spondylosis before intervening in infants and young children, make intervention plans and methods in advance, and avoid methods that are prone to causing problems.

[0053] Specifically, an embodiment of the resistance component in the above process is provided:

[0054] The resistance component includes an elastic sleeve 201 and a retainer 202 opened at the top of the elastic sleeve 201. The cervical spine component is sleeved on the outside of the elastic sleeve 201, and the retainer 202 is sleeved on the bending rod 103.

[0055] The elastic sleeve 201 is fitted onto the bending rod 103. The elastic sleeve 201 can tightly wrap around the bending rod 103 using its own elasticity, thereby protecting the bending rod 103 from being bumped or scratched by external objects during use. Moreover, when the cervical spine component is fitted onto the elastic sleeve 201, the contact and compression between them cause the elastic sleeve 201 to undergo elastic deformation, thereby making the cervical spine component tightly "hug" onto the elastic sleeve 201, enhancing the stability of the connection between the cervical spine component and the bending rod 103.

[0056] Specifically, an embodiment of the resistance component in the above process is provided:

[0057] The cervical spine assembly includes several bone models 301 and a pressure head 303 that can be inserted into a sleeve 202. The several bone models 301 are sequentially fitted onto the elastic sleeve 201 from top to bottom, and a cervical intervertebral disc model 302 is provided between every two adjacent bone models 301.

[0058] When assembling the cervical spine assembly, after the elastic sleeve 201 is placed on the bending rod 103, the first bone model 301 is placed on the elastic sleeve 201 from top to bottom and pushed downwards, so that the first bone model 301 moves to the bottom of the elastic sleeve 201. Then, the first cervical intervertebral disc model 302 is placed on the elastic sleeve 201 in the same way and pressed on the first bone model 301. Then, the above operation is repeated to assemble the second bone model 301 and the second cervical intervertebral disc model 302. The operation is repeated until all bone models 301 and cervical intervertebral disc models 302 are assembled in sequence. Finally, the pressure head 303 is inserted into the sleeve 202 and pressed on the uppermost bone model 301 to press the assembled bone models 301 tightly, preventing them from loosening and ensuring that the simulated bones do not fall apart when bending.

[0059] When the bending rod 103 bends, it can cause several bone models 301 and several cervical intervertebral disc models 302 to change their posture accordingly, thus simulating the changes in the skeleton and the intervertebral discs after cervical malformation. It can vividly simulate the skeletal condition of cervical malformation.

[0060] Specifically, an embodiment of the steering component in the above process is provided:

[0061] The steering assembly includes a housing 401 and a base 403 fastened to the lower end of the housing 401. A bearing 402 is connected to the inner wall of the housing 401. A base column 101 is connected to the inner ring of the bearing 402, and a rubber sleeve 102 is provided between the inner ring of the bearing 402 and the outer wall of the base column 101.

[0062] Rubber sleeve 102 is fitted onto the outer wall of base column 101, and then base column 101 is inserted into the inner ring of bearing 402. The outer wall of base column 101 and the inner ring of bearing 402 together compress rubber sleeve 102, causing rubber sleeve 102 to undergo elastic deformation. The elastic deformation of rubber sleeve 102 makes the connection between base column 101 and inner ring of bearing 402 more stable. When base column 101 rotates, the increased friction of rubber sleeve 102 can drive the inner ring of bearing 402 to rotate relative to the outer ring under the action of rollers. At the same time, taking advantage of the continued elastic deformation of rubber sleeve 102, when bending rod 103 bends and the center of gravity shifts, bending rod 103 can cause base column 101 to tilt slightly relative to inner ring of bearing 402. When the resistance component follows the tilt of base column 101 and bending rod 103 relative to inner ring of bearing 402, the resistance component can contact the upper surface of housing 401, and the friction at the contact point can be increased, making it more difficult for base column 101 to rotate.

[0063] By using the above method, it is possible to simulate cervical dysplasia while simultaneously using resistance components to simulate cervical spine rotation after cervical dysplasia, thereby gaining timely insight into the difficulty and situation of cervical spine rotation in infants and young children after cervical dysplasia.

[0064] Specifically, an example is provided for illustrating the form of frictional force change in the resistance component during the above process:

[0065] The resistance component also includes a disc 203 connected to the lower end of the elastic sleeve 201. A rubber pad 204 is provided on the lower end surface of the disc 203, and the rubber pad 204 rubs against the upper surface of the outer shell 401.

[0066] When the bending rod 103 bends, due to the shift in the center of gravity, the bending rod 103 will cause the base column 101 to tilt slightly relative to the inner ring of the bearing 402. During this tilting, the bending rod 103 will also tilt simultaneously with the bending. This will cause the disc 203 at the lower end of the elastic sleeve 201 to tilt, compressing the rubber pad 204 on the lower surface of the disc 203. As the rubber pad 204 undergoes elastic deformation, the frictional force between it and the upper surface of the outer shell 401 increases. This increases the frictional force that the base column 101 needs to overcome when rotating, increasing the force required to rotate the base column 101 and making rotation more difficult. This allows for a clearer and more accurate simulation of the difficulty and range of cervical spine rotation after a stroke, enabling medical staff to train and understand infantile stroke (already diagnosed) in advance and train the intervention force and angle to the optimal state. This avoids damage to the infant's cervical spine due to incorrect intervention without prior understanding and preparation.

[0067] Specifically, an embodiment of the muscle group components in the above process is provided:

[0068] The muscle group assembly includes a connecting seat 501 and a connecting plate 505. The connecting plate 505 is detachably connected to the disc 203, and the connecting seat 501 is detachably connected to the pressure head 303. A longus colli muscle model 504 is provided on the rear side between the connecting seat 501 and the connecting plate 505, and sternocleidomastoid muscle models 503 are provided on both sides between the connecting seat 501 and the connecting plate 505.

[0069] When simulating muscle changes, the connecting seat 501 is fixed to the pressure head 303, and the connecting plate 505 is fixed to the disc 203, so that the sternocleidomastoid muscle model 503 and the longus colli muscle model 504 surround the cervical spine component (several assembled bone models 301). The sternocleidomastoid muscle model 503 and the longus colli muscle model 504 are made of elastic materials, such as silicone or rubber. When the cervical spine component bends along with the bending rod 103, it can cause the sternocleidomastoid muscle model 503 and the longus colli muscle model 504 to undergo corresponding deformation.

[0070] The above method can simulate the characteristic and obvious changes in the muscles (sternocleidomastoid and longus colli) around the cervical spine after torticollis. This allows medical staff to perceive the changes in the muscles by touching the sternocleidomastoid model 503 and the longus colli model 504 during training. This enables them to conduct specialized (muscle massage) training in advance using the torticollis teaching device after simulating infantile torticollis (a diagnosed torticollis condition). This allows them to understand the changes and conditions of the muscles in advance and train methods, strengths, and angles suitable for treating torticollis patients.

[0071] Additionally, an example is provided for the connection method between the connecting seat 501 and the pressure head 303: a square post 502 can be provided on the lower end face of the connecting seat 501, and a square hole can be opened on the upper end of the pressure head 303. During connection, the square post 502 can be directly inserted into the square hole to complete the quick connection and facilitate disassembly for maintenance. At the same time, an example is provided for the connection method between the disc 203 and the connecting plate 505: a plug rod 506 can be provided on the connecting plate 505, and a socket 205 can be opened on the disc 203. The connection is completed by aligning the plug rod 506 with the socket 205 and inserting it. The process enables quick connection and disassembly.

[0072] In actual treatment, medical staff cannot directly observe changes in the muscle groups and bones around the cervical spine. Therefore, in order to simulate the changes more vividly and realistically during training, this application...

[0073] It also includes a skin component that wraps around the outside of the muscle group component to cover the muscle group component and the cervical spine component.

[0074] The skin component can be made of a leather material similar to human skin and wrapped around the outside of the muscle component, thus concealing the muscle and skeletal components. This prevents medical staff from directly seeing the muscle and skeletal components, allowing them to perceive changes and characteristics of muscles and bones through touch. This provides a more accurate training method for medical staff, thus avoiding problems caused by significant discrepancies between simulation and reality when treating infantile hemiplegia.

[0075] Specifically, an embodiment of the skin component in the above process is provided:

[0076] The skin component includes an elastic sheath 601, which wraps around the outside of the muscle group component. The elastic sheath 601 is broken vertically at a certain position, and a connector 602 is provided at the broken position to connect the broken position.

[0077] The connector 602 can be a zipper or other connector. By opening the connector 602, the elastic sheath 601 can be unfolded and then wrapped around the outside of the muscle group component, so that the elastic sheath 601 wraps around the sternocleidomastoid muscle model 503 and the longus colli muscle model 504. Then the connector 602 is closed to complete the wrapping, which can simulate the skin of the cervical spine. Medical staff can perform training by touching or gently pressing.

[0078] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
