Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a finger rehabilitation training device. Background Technology

[0002] After a finger fracture due to accidental impact or external compression, rehabilitation training is often required after treatment stages such as reduction and fixation. This is because the injury and fixation process can cause muscle atrophy around the finger and restrict joint mobility, affecting normal flexion, extension, and grasping functions. Cuts can lead to ruptures of the flexor or extensor tendons in the finger, or tendons can tear due to excessive stretching during certain sports. After surgical repair of the tendons, adhesions are common during the healing process. If rehabilitation training is not carried out promptly, it can severely affect the finger's flexion and extension functions, making it impossible for the finger to bend or straighten normally.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

[0035] like Figures 1 to 4 As shown, a preferred embodiment of the finger rehabilitation training device of this application includes: a base 1, a driving member 2, a rotating member 3, a first finger sleeve 41, and a second finger sleeve 42; the base 1 serves as the supporting foundation of the finger rehabilitation training device; the first finger sleeve 41 is used to wear the thumb and is connected to the base 1; the rotating member 3 is rotatably connected to the base 1 and has a rotation center line 311; the second finger sleeve 42 is used to wear the finger to be trained and is connected to the rotating member 3, and the second finger sleeve 42 is spaced apart from the rotation center line 311; the driving member 2 is connected to the base 1 and is configured to drive the rotating member 3 to rotate around the rotation center line 311, so that the rotating member 3 drives the second finger sleeve 42 to move closer to or away from the first finger sleeve 41. After the drive unit 2 is activated, it can drive the rotating unit 3 to rotate around its rotation center line 311. Since the second finger sleeve 42 is spaced from the rotation center line 311 and connected to the rotating unit 3, the rotation of the rotating unit 3 will cause the second finger sleeve 42 to make an arc motion, thereby realizing the second finger sleeve 42 moving closer to or further away from the first finger sleeve 41. This movement mode can simulate the flexion, extension, opening and closing of the fingers, helping the fingers to perform rehabilitation training, and is suitable for improving the range of motion and flexibility of the fingers.

[0036] In some embodiments of this application, the base 1 includes a base body 11 and a cantilever arm 12. The cantilever arm 12 is connected to the base body 11 and protrudes from the base body 11. A rotating member 3 is connected to one end of the cantilever arm 12 that protrudes from the base body 11. A first finger sleeve 41 and a driving member 2 are connected to the base body 11. Specifically, the rotating member 3 is connected to one end of the cantilever arm 12 that protrudes from the base body 11, which allows the rotation center line 311 to be located outside the base body 11. This arrangement allows the mounting position of the rotating member 3 to be biased towards one side of the base body 11, making it easier to leave space on the base body 11 to arrange the driving member 2. Moreover, setting the base 1 as a separate structure of the base body 11 and the cantilever arm 12 facilitates the processing and manufacturing of the base 1. In some embodiments of this application, the base 1 can be set as an integrally formed cam structure. The connection position between the rotating member 3 and the base 1 is set at the protruding part of the cam structure.

[0037] In some embodiments of this application, the rotating component 3 includes a connecting arm 31 and a mounting arm 32. The connecting arm 31 and the second finger sleeve 42 are respectively connected to both sides of the mounting arm 32 along its length. One end of the connecting arm 31 is connected to one side of the mounting arm 32 along its length, and the second finger sleeve 42 is connected to the other side of the mounting arm 32 along its length. The end of the connecting arm 31 away from the mounting arm 32 is rotatably connected to the end of the cantilever arm 12 protruding from the base body 11. The rotation center line 311 of the connecting arm 31 forms the rotation center line 311. The driving component 2 is connected to the mounting arm 32 in a transmission connection. The rotating component 3 is configured as a split structure composed of the connecting arm 31 and the mounting arm 32. After the connecting arm 31 and the mounting arm 32 are assembled, they remain fixed, facilitating the design and processing of connecting arms 31 of different lengths according to different body types. This facilitates the multi-specification design of the finger rehabilitation training device of this application and also facilitates the processing of the rotating component 3. In other embodiments of this application, the rotating component 3 can be configured as an integrally formed fan-shaped plate.

[0038] In some embodiments of this application, the mounting arm 32 includes a first connecting segment 321, an arc segment 322, and a second connecting segment 323 connected in sequence. The second finger sleeve 42 is connected to the second connecting segment 323, and the end of the connecting arm 31 away from the cantilever arm 12 is connected to the first connecting segment 321. The arc segment 322 includes a concave side 3221, which is arranged towards the rotation center line 311. A fan-shaped space 3223 is formed between the concave side 3221 and the rotation center line 311, and at least a portion of the cantilever arm 12 is located in the fan-shaped space 3223. By forming the fan-shaped space 3223 through the concave shape of the arc segment 322, sufficient clearance space can be reserved for the cantilever arm 12 when the rotating member 3 rotates around the rotation center line 311, avoiding structural interference between the mounting arm 32 and the cantilever arm 12 during movement, thereby ensuring smooth movement of the second finger sleeve 42 driven by the rotating member 3.

[0039] In some embodiments of this application, the length direction of the rotation center line 311 is the first direction Z. The driving component 2 includes a motor body 21 and a first output shaft 22. The motor body 21 is connected to one side of the base body 11 in the first direction Z, and the connecting arm 31 and the mounting arm 32 are arranged on the other side of the base body 11 in the first direction Z. The first output shaft 22 passes through the base body 11 and is drively connected to the mounting arm 32. By arranging the motor body 21 and the rotating component 3 on both sides of the base body 11, effective power transmission is achieved, and spatial interference between the driving component 2 and the rotating component 3 is avoided, making the overall structure of the finger rehabilitation training device of this application more compact.

[0040] In some embodiments of this application, the mounting arm 32 includes a connecting portion 3224, and the finger rehabilitation training device also includes a transmission rope 5. The transmission rope 5 includes a first winding section 51, a second winding section 53, and a sleeve section 52. The first winding section 51 and the second winding section 53 are wound around the first output shaft 22, and the winding directions of the first winding section 51 and the second winding section 53 are opposite. The sleeve section 52 is sleeved on the connecting portion 3224, and the two ends of the sleeve section 52 are respectively connected to the first winding section 51 and the second winding section 53. Specifically, the connecting part 3224 is disposed on the arc segment 322, the arc segment 322 includes an outwardly convex side 3222, the outwardly convex side 3222 is arranged at intervals relative to the first output shaft 22 in the radial direction of the arc segment 322; in the first direction Z, the side of the arc segment 322 away from the base body 11 has a groove 3225, the groove wall of the groove 3225 forms the connecting part 3224, and a cover 33 is detachably connected to the groove opening of the groove 3225. After the sleeve segment 52 is sleeved on the connecting part 3224, the cover 33 is connected to the mounting arm 32 to seal the main groove opening, and the cover 33 can prevent the sleeve segment from coming out. When the motor body 21 drives the first output shaft 22 to rotate clockwise, the first winding section 51 is wound up and the second winding section 53 is released, and the sleeve section 52 drives the mounting arm 32 to rotate counterclockwise around the rotation center line 311; when the motor body 21 drives the first output shaft 22 to rotate counterclockwise, the first winding section 51 is released and the second winding section 53 is wound up, and the sleeve section 52 drives the mounting arm 32 to rotate clockwise around the rotation center line 311, thereby realizing the flexion and extension training action of the second finger sleeve 42. In other embodiments of this application, an external rack can be provided on the convex side 3222, and a gear can be connected to the first output shaft 22. The gear meshes with the rack, and the motor drives the rotating part 3 through the gear and rack structure.

[0041] In some embodiments of this application, the cantilever arm 12 includes a support section 121 and a cantilever section 122. The support section 121 is connected to the side of the base body 11 away from the motor body 21; the cantilever section 122 is connected to the side of the support section 121 away from the base body 11, and a connecting arm 31 is rotatably connected to the side of the cantilever section 122 away from the support section 121. The support section 121 is spaced apart from the first output shaft 22, and the mounting arm 32 passes through the gap between the support section 121 and the first output shaft 22. Specifically, the support section 121 is connected to the side of the base body 11 away from the motor body 21 in the first direction Z. The support section 121 extends along the first direction Z. In the first direction Z, one side of the support section 121 is connected to the base body 11, and the other side of the support section 121 is connected to the support section 121. The cantilever section 122 extends perpendicularly to the first direction Z. In this embodiment, the base body 11 is a circular disc, and the thickness direction of the base body 11 is arranged along the first direction Z. The axis of the base body 11 is parallel to and spaced apart from the rotation center line 311. The end of the cantilever section 122 away from the support section 121 extends away from the base body 11 along the diameter direction of the base body 11. The end of the connecting arm 31 away from the mounting arm 32 is rotatably connected to the end of the support section 121 away from the support section 121. In the diameter direction of the base body 11, the support section 121 and the first output shaft 22 are arranged at intervals. The arc section 322 passes through the interval between the support section 121 and the first output shaft 22, thereby making the structure of the finger rehabilitation training device in this embodiment more compact.

[0042] In some embodiments of this application, the finger rehabilitation training device further includes a fixing member 61 and a connecting post 62. In the first direction Z, the fixing member 61 and the base body 11 are spaced apart. The connecting post 62 connects the base body 11 and the fixing member 61. The mounting arm 32 passes through the gap between the fixing member 61 and the base body 11. At least a portion of the first output shaft 22 is arranged in the gap between the fixing member 61 and the base body 11. Specifically, the fixing member 61 is connected to the base body 11 via multiple connecting posts 62. In the first direction Z, the gap between the fixing member 61 and the base body 11 forms the mounting space for the transmission rope 5, the first output shaft 22, and the mounting arm 32. The fixing member 61 can protect the first winding segment 51 and the second winding segment 53. In some embodiments of this application, the end of the support segment 121 facing away from the base body 11 is also connected to the fixing member 61, thereby increasing the stability of the support segment 121. In some embodiments of this application, the fixing member 61 is provided with bolt holes or slot-type connecting structures for connecting the fixing member 61 to the mounting frame. Connecting the fixing member 61 to the mounting frame allows the finger rehabilitation training device to be fixed as a whole. For users who find it inconvenient to hold the finger rehabilitation training device with their arm strength, the finger rehabilitation training device of this embodiment can be fixed to the mounting frame first by the fixing member 61, and then the index finger and the finger to be trained can be inserted into the first finger sleeve 41 and the second finger sleeve 42 respectively. During the training process, the mounting frame is used to keep the finger rehabilitation training device fixed, without requiring the patient to exert force with their arm. For patients who can use their arm to hold the finger rehabilitation training device, they can freely choose whether or not to connect the fixing member 61 to the mounting frame.

[0043] In some embodiments of this application, the first finger sleeve 41 and the motor body 21 are located on the same side of the base body 11 in the first direction Z, and the first finger sleeve 41 is arranged close to the outer periphery of the motor body 21. The motor body 21 is configured to be gripped in the hand. Arranging the first finger sleeve 41 and the motor body 21 on the same side and placing the first finger sleeve 41 close to the outer periphery of the motor body 21 allows for a more compact layout of the finger rehabilitation training device, reducing space occupation. Moreover, setting the motor body 21 in a gripping form allows the user to hold the motor body 21 in their hand during finger rehabilitation training, which conforms to ergonomic principles and provides a more comfortable user experience. Specifically, the motor body 21 is cylindrical in shape.

[0044] In some embodiments of this application, the finger rehabilitation training device further includes an encoder 7, and the motor is a single-output-shaft motor, with the encoder 7 connected to the first output shaft 22; or the motor is a dual-output-shaft motor, which also includes a second output shaft 23. In the first direction Z, the second output shaft 23 is connected to the side of the motor body 21 opposite to the first output shaft 22, and the encoder 7 is connected to the second output shaft 23. Through the connection between the encoder 7 and the motor output shaft, parameters such as the motor's rotation angle and speed can be accurately detected, thereby monitoring the movement state of the rotating component 3 and the second finger sleeve 42 in real time. This facilitates control of the amplitude and speed of finger training, preventing excessive amplitude or speed. In this embodiment, the motor is a dual-output-shaft motor, and the encoder 7 is connected to the second output shaft 23. The encoder 7 can be installed using the independent space on the side of the motor body 21 opposite to the rotating component 3, facilitating the installation and maintenance of the encoder 7.

[0045] In some embodiments of this application, the finger rehabilitation training device further includes an angle limiting mechanism 8. The angle limiting mechanism 8 includes a limiting groove 81 and a limiting protrusion 82. One of the limiting groove 81 and the limiting protrusion 82 is disposed on the cantilever arm 12, and the other is disposed on the rotating member 3. At least a portion of the limiting protrusion 82 is located in the limiting groove 81 to limit the rotation angle of the rotating member 3. The design of the angle limiting mechanism 8, through the cooperation of the limiting groove 81 and the limiting protrusion 82, controls the maximum rotation range of the rotating member 3, avoiding secondary injury to the injured finger due to excessive rotation angle, thus providing a safety guarantee for rehabilitation training. In this embodiment, the limiting groove 81 is disposed on the cantilever arm 12, and the limiting protrusion 82 is disposed on the connecting arm 31. The groove wall of the limiting groove 81 can block the limiting protrusion 82, thereby limiting the rotation angle of the connecting arm 31, and further limiting the rotation angle of the mounting arm 32.

[0046] In some embodiments of this application, the finger rehabilitation training device further includes a first connecting plate 91 connected to the rotating member 3. Multiple second finger sleeves 42 are connected to the first connecting plate 91 and are arranged sequentially along the rotation center line 311. Specifically, the length direction of the first connecting plate 91 is parallel to the rotation center line 311. The motor body 21 is cylindrical, and its axis, rotation center line 311, and first connecting plate 91 are arranged parallel and spaced apart. Multiple second finger sleeves 42 are arranged sequentially along the length direction of the first connecting plate 91. In use, all fingers except the thumb can be inserted into their corresponding second finger sleeves 42 to achieve synchronous training of multiple fingers.

[0047] In some embodiments of this application, a first connecting plate is rotatably connected to a rotating shaft, which is arranged parallel to the rotation center line 311. A second connecting section 323 is provided with a mounting hole for mounting the rotating shaft, the axis of which is arranged parallel to the rotation center line 311. The second connecting section 323 is also connected to a locking screw, the threaded end of which passes through the wall of the mounting hole and abuts against the rotating shaft located in the mounting hole. Loosening the locking screw allows the threaded end of the locking screw to disengage from the side wall of the rotating shaft, thereby unlocking the rotating shaft and allowing it to move along the axis of the mounting hole. Tightening the locking screw allows the threaded end of the locking screw to press against the side wall of the rotating shaft, thereby fixing the rotating shaft in the second connecting section 323 and locking it.

[0048] In some embodiments of this application, the finger rehabilitation training device further includes a second connecting plate 92, which is connected to the peripheral edge of the base body 11, and the first finger sleeve 41 is connected to the second connecting plate 92.

[0049] In some embodiments of this application, the inner diameters of the first finger sleeve 41 and the second finger sleeve 42 are adjustable, allowing them to fit fingers of different sizes. Specifically, the first finger sleeve 41 and the second finger sleeve 42 are in the form of Velcro. The middle portion of the first finger sleeve 41 is fixed to the second connecting plate 92, and the two ends of the first finger sleeve 41 are wrapped around the first finger and then glued. The middle portion of the second finger sleeve 42 is fixed to the first connecting plate 91, and the two ends of the second finger sleeve 42 are wrapped around the second finger and then glued.

[0050] In summary, the finger rehabilitation training device of this application includes a base 1, a driving component 2, a rotating component 3, a first finger sleeve 41, and a second finger sleeve 42. The first finger sleeve 41 is used to wear the thumb and is connected to the base 1. The rotating component 3 is rotatably connected to the base 1 and has a rotation center line 311. The second finger sleeve 42 is used to wear the finger to be trained and is connected to the rotating component 3, with the second finger sleeve 42 and the rotation center line 311 spaced apart. The driving component 2 is connected to the base 1 and can drive the rotating component 3 to rotate around the rotation center line 311. Since the second finger sleeve 42 is connected to the rotating tip and is spaced apart from the rotation center line 311, the rotating component 3 will drive the second finger sleeve 42 to make an arc motion when it rotates, and make the second finger sleeve 42 move closer to or away from the first finger sleeve 41. The movement trajectory of the second finger sleeve 42 is an arc, which conforms to the natural movement trajectory of the finger, thereby realizing the rehabilitation training of the finger.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
