Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a game-type task-oriented forearm rotation rehabilitation training device. Background Art
[0002] In orthopedic clinical practice, the reduction or loss of forearm rotation function is a symptom of many diseases such as congenital fusion of the radius and ulna (common in children), elbow stiffness, radius and ulna fractures, and heterotopic ossification. These symptoms significantly reduce the patient's ability to take care of themselves. In order to improve the rotation function of the forearm and improve the patient's quality of life, the doctor will develop a surgical correction plan based on the patient's specific situation. However, the success of the operation is not the end of the treatment, and the subsequent rehabilitation stage is also crucial. In order to ensure the best correction effect, at least three months of systematic rehabilitation training is required after surgery to rebuild muscle memory and restore the rotation function of the forearm.
[0003] The current method of postoperative forearm rotation rehabilitation training is that the patient bends the elbow joint to 90 degrees and keeps it close to the torso, holding a dumbbell or water bottle of appropriate weight to perform pronation and supination training. Pronation refers to the movement of turning the back of the hand upward starting from the neutral position of the forearm (that is, when the elbow is bent 90 degrees, the hand is clenched into a fist and the thumb is facing up); while supination is the process of turning the back of the hand from facing up to facing down. The pronation and supination angles of normal people can reach 0°-80° and 0°-100° respectively. Although this method is effective to a certain extent, it also has several significant problems:
[0004] 1. The cooperation problem of child patients: Since children have difficulty concentrating for a long time and lack the persistence of adults, they often find it difficult to complete multiple sets of boring rehabilitation training, resulting in limited training results.
[0005] 2. Lack of goal orientation and task management: The lack of clear goals and task management during the training process makes it impossible to intuitively demonstrate the training results, which reduces the patient's motivation to train.
[0006] 3. Subjectivity in rehabilitation effect evaluation: Currently, rehabilitation effect is mainly evaluated by observing the approximate changes in rotation angle with the naked eye. This method lacks precision and objectivity, making it difficult to accurately quantify rehabilitation progress.
[0007] The above problems jointly restrict the maximization of patients' postoperative rehabilitation effects. Utility Model Content

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the template description herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention.

[0038] An embodiment of the present application provides a game-like task-oriented forearm rotation rehabilitation training device, which can be used for patient forearm muscle rehabilitation training, and can increase the fun of rehabilitation training, quantify training results and provide timely feedback, thereby improving patients' training interest, helping patients establish a positive feedback mechanism, and improving training effects.
[0039] like Figure 1 As shown, the game-style task-oriented forearm rotation rehabilitation training device includes a mounting housing 100 , a rotation handle 200 and a feedback assembly 300 .
[0040] like Figure 2 As shown, the mounting shell 100 is provided with a first assembly through hole 110, and the mounting shell 100 provides a mounting base for other components. The mounting shell 100 is set on a desktop or other table, and the patient can also hold the mounting shell 100 directly or indirectly.
[0041] like Figure 1 As shown, the rotating handle 200 is disposed in the first assembly through-hole 110, and both ends of the rotating handle 200 are capable of sliding relative to the inner wall of the first assembly through-hole 110. During use, the patient grasps the rotating handle 200 and rotates the forearm, driving the rotating handle 200 to rotate relative to the mounting housing 100 to perform forearm rotation training.
[0042] like Figure 1 As shown, the feedback component 300 is set on the mounting housing 100. The feedback component 300 includes a controller, a feedback unit and a detection unit. The controller is electrically connected to the feedback unit and the detection unit. The detection unit is used to detect the rotation angle of the rotating handle 200 and convert the detection result into an electrical signal and send it to the controller. The controller controls the feedback unit to send a feedback signal to the outside world according to the detection result. By way of example, the feedback signal includes but is not limited to sound signals, somatosensory vibration signals and light signals.
[0043] For example, there is no limitation on the model of the controller, for example, Renesas' 2SJ210(0)-T1B-AT and 5V41235NLG8 can be used. The above is only an example and does not limit the scope of protection of this application.
[0044] During use, the patient stands or sits, bends their elbow 90° against their torso, and holds the middle or other part of the rotating handle 200 of the device with their affected hand. A family member or rehabilitation therapist stands opposite the patient and, depending on the patient's tolerance, performs pronation and supination exercises starting from 0° (neutral position, with the rotating handle 200 in a vertical direction). After a preliminary assessment of the rotation angle, the family member guides the patient's forearm to passively rotate to the tolerated angle. After the detection unit detects that the rotating handle 200 has rotated to the patient's tolerated angle, the detection result is sent to the controller. The controller counts the number of detected times and controls the feedback unit to send a feedback signal to the outside world. Exercises can be grouped together, and after completion, the controller records the training count for that day. After daily training, the passive motion angle is gradually increased to encourage the patient to complete passive rotation exercises at larger angles. The family member can set a rehabilitation game goal, such as increasing the number of times per group by 5 per day. After informing the patient, the patient can remember the target score value during training. After each completion, the controller records the cumulative value to increase the initiative and fun of the training. Of course, the above is only an example, and the use process of this embodiment is not limited to this, nor does it mean to limit the scope of protection of this application.
[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the feedback assembly 300 includes a rotating housing 310, which is mounted within the first assembly hole 110 of the mounting housing 100. The rotating housing 310 is provided with a second assembly hole 320 whose axis is parallel to the axis of the first assembly hole 110. The second assembly hole 320 is coaxial with the first assembly hole 110. In another embodiment, the axis of the second assembly hole 320 is not coaxial with the axis of the first assembly hole 110.
[0046] The ends of the rotating handle 200 are slidably mounted on the inner wall of the second assembly hole 320, allowing the ends of the rotating handle 200 to rotate about the axis of the second assembly hole 320. The detection unit is disposed on the rotating housing 310. The inner wall of the second assembly hole 320 can limit the position of the rotating handle 200 along the radial direction of the second assembly hole 320, so that the rotating handle 200 can only rotate about the axis of the second assembly hole 320.
[0047] Both ends of the rotating handle 200 are slidably mounted on the inner wall of the second assembly through hole 320, allowing the rotating handle 200 to rotate freely around the axis of the second assembly through hole 320. This design provides good rotational flexibility and patient operation experience, and the patient can train the forearm muscles by rotating the rotating handle 200.
[0048] In one embodiment, the rotating handle 200 has a first end and a second end. For example, in the initial state, the rotating handle 200 is vertically positioned, with the first end and the second end sequentially located along the direction of gravity. In some embodiments, when determining the rotation angle of the rotating handle 200, the angle between the first end and the vertical direction (i.e., the direction of gravity) is used as a reference.
[0049] The detection unit includes a trigger and a sensor. The trigger is fixedly mounted on the first end of the rotary handle 200 . The rotary handle 200 rotates around the axis of the second assembly through hole 320 to drive the trigger to rotate around the axis of the second assembly through hole 320 .
[0050] The sensing element is fixedly disposed on the rotating housing 310 and is electrically connected to the controller. The sensing element is used to detect the trigger element and send the detection result to the controller.
[0051] Illustratively, a first sliding block is fixedly disposed on the first end of the rotating handle 200, a second sliding block is disposed on the second end, a slideway is circumferentially disposed on the inner wall of the second assembly through-hole 320 around the axis of the second assembly through-hole 320, and the first and second sliding blocks are slidably mounted in the slideway, thereby causing the first and second ends to rotate around the axis of the second assembly through-hole 320. In other embodiments, a first T-groove is disposed on the first end of the rotating handle 200, a second T-groove is disposed on the second end of the rotating handle 200, and a T-guide rail is disposed on the inner wall of the second assembly through-hole 320. The first and second T-grooves slidably cooperate with the T-guide rail, thereby causing the first and second ends to rotate around the axis of the second assembly through-hole 320.
[0052] For example, the sensing element can be set at the end face of the second assembly through hole 320. Initially, the rotating handle 200 is in a vertical state. The sensing element is set at the end face of the second assembly through hole 320 at a certain angle relative to the vertical direction. For example, the sensing element is set at a 30° position relative to the setting direction. When the patient rotates the rotating handle 200 to 30°, the sensing element detects the trigger element and sends the detection result to the controller. After receiving the detection result, the controller controls the feedback unit to send a feedback signal. At this point, the patient completes a forearm rehabilitation training. The patient then rotates the rotating handle 200 to reset it to the vertical state and then repeats the training. Of course, the sensing element can also be adjusted to other angles according to actual needs, such as being set at 45°, etc., which is not limited here.
[0053] In one embodiment, the sensing element is a normally open contact-free switch, which is de-energized when not triggered by the trigger element. The trigger element is a push block, and the contact-free switch is disposed in the rotational path of the push block. Rotating the handle 200 drives the push block, causing the push block to push against the contacts of the contact switch during rotation, energizing the contact-free switch. The contact-free switch then transmits an electrical signal to the controller, which, upon receiving the electrical signal, controls the feedback unit to transmit a feedback signal.
[0054] By fixing a trigger member on the first end of the rotating handle 200 and cooperating with the sensing member fixed on the rotating shell 310, accurate detection of the rotation angle of the rotating handle 200 is achieved. This design can ensure that when the patient is undergoing rehabilitation training, when the rotating handle 200 is rotated to a predetermined angle (such as 30° or 45°), the trigger member can be accurately detected by the sensing member, thereby triggering the feedback signal of the feedback unit. Through the precise trigger mechanism and real-time feedback function, the necessary safety guarantees can be provided when the patient is undergoing rehabilitation training. Once the patient reaches the predetermined training angle, the feedback signal will be issued in time, thereby avoiding the risk of overtraining or injury to the patient.
[0055] like Figure 3 、 Figure 4 As shown, in one embodiment, the detection unit includes a fixed housing 330, which is fixedly mounted within the rotating housing 310. The fixed housing 330 defines a hollow chamber within which the sensing element is disposed. Placing the sensing element within the hollow chamber within the fixed housing 330 effectively protects the sensing element from interference and damage from the external environment. This design improves the stability and reliability of the sensing element and extends its service life.
[0056] Exemplarily, the fixed shell 330 is a circular shell structure. Exemplarily, the outer surface color of the fixed shell 330 is a striking color, such as red, orange or yellow.
[0057] like Figure 5 As shown, the rotating housing 310 is made of a transparent material. For example, the transparent material includes but is not limited to glass, polymethyl methacrylate, polycarbonate, polyethylene terephthalate, transparent nylon or polystyrene.
[0058] The rotating housing 310 is made of a transparent material, allowing the patient to visually observe the rotation of the rotating handle 200 and the trigger, as well as the working status of the sensing element. This transparency not only enhances the patient's user experience but also helps to promptly identify and resolve potential problems.
[0059] The transparent rotating housing 310 makes the internal working mechanism of the mechanical structure more intuitive and interesting, thereby enhancing the patient's sense of participation and satisfaction during use. This design helps to enhance the patient's trust and favorability in the device.
[0060] The transparent rotating housing 310 can also be customized in color, texture, and other aspects as needed to meet the aesthetic and personalized needs of different patients. This flexibility makes the mechanical structure more in line with market demand and patient expectations.
[0061] In one embodiment, the sensing element is a Hall sensor, the triggering element is a magnetic element, and the rotating handle 200 drives the magnetic element to rotate. The Hall sensor is used to detect the magnetic field strength of the magnetic element and send the detection result to the controller. When the Hall sensor detects that the magnetic field strength of the magnetic element is greater than or equal to a first preset value, the controller controls the feedback unit to send a feedback signal.
[0062] During use, the patient rotates the rotary handle 200, which in turn drives the magnetic element. When the magnetic element approaches the Hall sensor, the sensor begins detecting its magnetic field strength. When the magnetic field strength reaches a first preset value, the Hall sensor converts the detection result into an electrical signal and transmits it to the controller. The controller determines that the first end of the rotary handle 200 is near the Hall sensor and has been rotated to a preset angle, and then controls the feedback unit to generate a feedback signal.
[0063] For example, the first preset value can be set according to actual needs. For example, the magnetic component includes but is not limited to a permanent magnet, a soft magnet, and the like.
[0064] Thanks to its non-contact detection method, the mechanical structure generates no mechanical shock or friction during operation, reducing failure rates and safety risks. Furthermore, the real-time feedback mechanism helps prevent patient injuries from overtraining. The Hall effect sensor and magnetic components are relatively simple in structure and do not require direct contact, making maintenance relatively easy. When replacement or repair is necessary, the relevant components can be easily removed and installed, reducing maintenance costs and time.
[0065] In one embodiment, the rotating housing 310 is rotatably mounted in the first assembly through hole 110, and the rotation of the rotating housing 310 drives the sensing element to rotate. The position of the sensing element is then adjusted by rotating the rotating housing 310. For example, when a patient needs to train the forearm to rotate forward 80°, initially, the sensing element is located above the rotating housing 310 in the vertical direction. The rotating housing 310 is rotated to rotate the sensing element 80° relative to the vertical direction. The patient then holds the rotating handle 200 and rotates it forward 80°. The triggering element triggers the sensing element. After the sensing element detects the triggering element, it sends the detection result to the controller. The controller controls the feedback unit to send a feedback signal. When the patient needs to train the forearm to rotate forward 45°, the rotating housing 310 is rotated to rotate the sensing element 45° relative to the vertical direction.
[0066] This mechanical structure design allows for personalized training based on the specific needs of the patient. Whether the forearm needs to be rotated 80 degrees or 45 degrees, the position of the sensor can be adjusted by simply rotating the housing 310 to meet the training needs of different patients.
[0067] By rotating the housing 310 to adjust the position of the sensor, the mechanical structure offers high flexibility. Medical staff or patients can adjust the training angle at any time based on actual conditions and training goals, without having to replace or adjust complex mechanical components. Personalized training and increased flexibility provide patients with a better rehabilitation experience using this mechanical structure. They can train according to their needs and progress, ensuring targeted and effective training.
[0068] In one embodiment, a telescopic hole is provided on the circumferential surface of one side of the rotating shell 310 close to the inner wall of the first assembly through hole 110, and an elastic member capable of telescoping and rebounding is provided in the telescopic hole. A telescopic block is also slidably provided in the telescopic hole, and the telescopic block includes a block portion and a wedge-shaped portion. The elastic member can exert a force on the telescopic block to cause the wedge-shaped portion to extend out of the telescopic hole.
[0069] A stopping hole is provided on the inner wall of the first assembly through hole 110, and the wedge-shaped portion extends out of the telescopic hole and enters the stopping hole. When a rotational force less than or equal to a second preset value is applied to the rotating shell 310, the telescopic block stops the rotating shell 310 from rotating relative to the mounting shell 100; when the rotating shell 310 needs to be rotated, a rotational force greater than the second preset value is applied to the rotating shell 310, so that the wall surface of the stopping hole on the inner wall of the first assembly through hole 110 stops the wedge-shaped portion, and the inclined surface of the wedge-shaped portion guides the block portion to move into the telescopic hole, thereby retracting the wedge-shaped portion and the block portion into the telescopic hole, so that the rotating shell 310 can rotate relative to the mounting shell 100, thereby adjusting the angle of the rotating shell 310 and the angle of the sensing part relative to the vertical direction.
[0070] When a rotational force less than or equal to a second preset value is applied to the rotating housing 310, the wedge-shaped portion of the telescopic block extends out of the telescopic hole and into the stop hole, effectively preventing further rotation of the rotating housing 310. This design prevents unintended rotation caused by accidental contact or slight vibration, thereby increasing the stability of the mechanical structure and safety during use.
[0071] When the position of the rotating housing 310 needs to be adjusted, a rotational force greater than the second preset value is applied to overcome the force of the elastic member on the telescopic block, causing the wedge-shaped portion to withdraw from the stop hole, thereby allowing the rotating housing 310 to rotate relative to the mounting housing 100. This design makes the adjustment process simple and quick, and improves usage efficiency.
[0072] In some embodiments, two or more stop holes are provided around the axis of the first assembly through hole 110. Since two or more stop holes are provided around the axis of the first assembly through hole 110, the rotating housing 310 can be locked at multiple angles. This multi-angle locking design makes the mechanical structure more flexible and adaptable, meeting the positioning requirements of different usage scenarios and needs.
[0073] For example, two stop holes are provided, and the two stop holes are vertically distributed on the inner wall of the first assembly hole 110. The telescopic block can be locked every 180° of rotation of the rotating housing 310. In some embodiments, four stop holes are provided, and the arc between adjacent stop holes is π / 2. The telescopic block can be locked every 90° of rotation of the rotating housing 310. In another embodiment, seven stop holes are provided, and the seven stop holes are symmetrically distributed along the vertical direction on the inner wall of the first assembly hole 110. The arc between adjacent stop holes is π / 6.
[0074] Exemplarily, the elastic member is at least one of the following: a coil spring, a leaf spring, or an air spring.
[0075] like Figure 1 As shown, in one embodiment, at least one counterweight 210 is provided on one end of the rotating handle 200. For example, a mounting groove is provided on the first end of the rotating handle 200, and the counterweight 210 is arranged in the mounting groove of the first end by means of clipping, gluing, bolting, etc.
[0076] Exemplarily, the counterweight 210 is at least one of the following: a container capable of storing liquids, a shell capable of storing solids, etc. Exemplarily, the liquid stored in the container includes but is not limited to water, etc. Exemplarily, the solid stored in the shell is a fixed substance such as metal or salt.
[0077] In one embodiment, one counterweight 210 is provided. In another embodiment, two counterweights 210 are provided. In other embodiments, four counterweights 210 are provided. The number of counterweights 210 can be configured according to the different needs of the patient.
[0078] For example, a lifting handle is provided on the weight piece 210 to facilitate gripping the weight piece 210 and to facilitate replacement or transportation of the weight piece 210. When a patient uses the game-like task-oriented forearm rotation rehabilitation training device provided by an embodiment of the present application, the rehabilitation training can be performed in the order of passive training first and then active training.
[0079] When performing passive forearm exercises, the patient stands or sits, bends their elbow 90° against their torso, and holds the rotation handle on their affected side. A family member or rehabilitation therapist stands opposite the patient, holding the rotation handle 200°. Pronation and supination are performed starting from 0° (neutral) based on the patient's tolerance. After a preliminary assessment of the rotation angle, the colored fixation shell 330 is rotated to the patient's tolerance. The family member guides the patient as they passively rotate their forearm until it reaches the angle indicated by the colored fixation shell 330, and counts are obtained. The patient can practice in groups, and after completion, the daily training count is recorded. After daily training, the passive motion angle is gradually increased, increasing the angle indicated by the fixation shell 330 to encourage the patient to complete larger passive rotations. Family members can set rehabilitation game goals, such as increasing the number of repetitions per set by 5 per day. After informing the patient, the family member can remind the patient of the target score during training. Points are awarded for rotating the colored fixation shell 330. The cumulative value is displayed on the display screen 340 after each completed repetition, increasing the initiative and interest of the training.
[0080] When the patient performs active rotation training of the forearm, the counterweight 210 can be omitted or the number of counterweights 210 can be configured according to the patient's tolerance. The patient takes a standing or sitting position, bends the elbow 90° close to the torso, holds the rotating handle 200 of the device with the affected hand, and starts to rotate forward or backward from 0° (neutral position). After self-assessing the tolerance level, the patient can rotate the rotating shell 310 by himself and rotate the colored fixed shell 330 to the appropriate angle to set the target. The patient can regard rehabilitation training as a sniper game with a colored fixed shell 330. As long as the fixed shell 330 is rotated to the target angle and reaches the fixed shell 330, the patient can score. The display screen 340 can display the score value. The score can be counted daily and the next day's goal can be set according to the score of the day. There is both a visual goal and mental motivation by completing the task to obtain points, which increases the fun and initiative of rehabilitation.
