DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0020] As described in the background art, existing rehabilitation training devices cannot meet the personalized rehabilitation needs of different parts of the hand and different degrees of injury.

[0021] In order to solve this technical problem, the present invention provides an adjustable orthopedic rehabilitation exercise device, which is used for partial bending training of fingers.

[0022] Specifically, please refer to Figure 1-Figure 9The adjustable orthopedic rehabilitation exercise device comprises a back-of-hand support seat 1 and a finger bending plate 2, wherein a plurality of finger bending plates 2 are symmetrically arranged on the back-of-hand support seat 1, and an exercise mechanism for exercising the hand to be rehabilitated is arranged on the back-of-hand support seat 1; The exercise mechanism includes a restraint belt 3, a protective plate 4, a groove 5 and a hollow plate 6. The restraint belt 3 is fixed on the finger bending plate 2 for restraining the fingers. The protective plate 4 is fixed on the finger bending plate 2. The groove 5 is provided on the back of the hand support seat 1 for installing and placing the hollow plate 6. The hollow plate 6 is also fixedly connected with a micro air pump 7 for conveying gas. The hollow plate 6 is also fixedly connected with five installation pipes 8. The installation pipe 8 is also threadedly connected with a silicone hose 9 for cooperating with the finger bending plate 2 to straighten the fingers. A first Velcro 301 for limiting the position of fingers is fixed on the restraining belt 3 , and a second Velcro 302 for cooperating with and bonding the first Velcro 301 is fixed on the protective plate 4 .

[0023] The patient places the hand to be rehabilitated steadily on the back of the hand support seat 1, and places the fingers one by one on the finger bending plate 2. The first Velcro 301 on the restraint belt 3 and the second Velcro 302 on the protective plate 4 are bonded together to restrain and limit the fingers. When the micro air pump 7 starts to work, it transports gas into the hollow plate 6, and the gas then enters the silicone hose 9 through the installation tube 8. At this time, the silicone hose 9 is inflated to generate thrust to push the finger bending plate 2, assist the fingers to straighten, and then drive the fingers to stretch. When the silicone hose 9 stops inflating, the finger bending plate 2 is twisted. The torsional force of the spring 202 drives the fingers to naturally restore the bent state, and this is repeated rhythmically to achieve regular gripping and stretching movements of the fingers, thereby achieving a good rehabilitation exercise purpose. At the same time, the patient can independently increase the confrontation training with the finger bending plate 2 according to his or her own rehabilitation situation. When the finger bending plate 2 drives the fingers to bend, the patient actively applies force to prevent the bending, or applies reverse resistance during the process of straightening the fingers, thereby further enhancing the strength and flexibility of the hand muscles, achieving an adjustable effect, and ensuring that the device can better meet the needs of patients at different stages of rehabilitation and accelerate the rehabilitation process.

[0024] The present invention provides an adjustable orthopedic rehabilitation exercise device. The device provides a stable and comfortable support for the patient's hand through a back-of-hand support seat 1 and a finger bending plate 2, while providing a reasonable and accurate movement guide, which greatly helps to improve the effect and safety of rehabilitation training. The fingers can move on the correct trajectory, avoiding secondary injuries caused by wrong movements. The cooperation of the micro air pump 7 and the silicone hose 9 can accurately control the extension strength and amplitude of the fingers, realize highly personalized rehabilitation training, fully meet the unique needs of different patients, and can be flexibly adjusted according to the patient's rehabilitation progress, with strong adaptability.

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0028] Please refer to Figure 5-Figure 9 , an adjustable orthopedic rehabilitation exercise device, whose exercise mechanism also includes a through groove 11, a mounting groove 12 and a push plate 13. The through groove 11 is linearly distributed and opened on the back of the hand support seat 1 and the hollow plate 6 and is connected with the mounting groove 12. The push plate 13 is arranged in the mounting groove 12. A massage convex plate 14 for massaging the back of the hand to be rehabilitated is also fixed on the push plate 13. A reset spring 15 for driving the massage convex plate 14 to reset is also symmetrically fixed on the push plate 13; when the micro air pump 7 inflates air into the hollow plate 6, the gas enters the mounting groove 12 through the through groove 11, pushing the push plate 13 to move forward, and the massage convex plate 14 on the push plate 13 moves forward accordingly, contacts and presses the back of the hand to be rehabilitated, and realizes the massage function. When the gas supply stops, under the action of the reset spring 15, the push plate 13 drives the massage convex plate 14 to reset. While the patient is performing finger rehabilitation training, the back of the hand can be massaged synchronously, further enhancing the rehabilitation effect and relieving hand fatigue and tension.

[0029] The gas is smoothly transmitted from the hollow plate 6 to the mounting groove 12 through the through groove 11, thereby ensuring the power supply for the push plate 13 to push. The mounting groove 12 provides space and guidance for the movement of the push plate 13. The cooperation between the push plate 13 and the massage convex plate 14 can effectively convert the power of the gas into massage action, directly pressing and stimulating the back of the patient's hand, promoting blood circulation and muscle relaxation.

[0030] Please refer to Figure 1-Figure 8, an adjustable orthopedic rehabilitation exercise device, wherein the back of the hand support seat 1 is provided with an expansion mechanism for expanding the fingers to be rehabilitated, the expansion mechanism comprising an expansion slot 16, a rotating block 17 and a support plate 18, the expansion slot 16 is symmetrically arranged on the back of the hand support seat 1 and is rotatably connected to the rotating block 17, the rotating block 17 is fixedly connected to a plurality of finger bending plates 2, the support plate 18 is symmetrically arranged on the back of the hand support seat 1 and the finger bending plate 2, and a first rotating disk 19 is also rotated on one side of the support plate 18; when the patient places his hand naturally and comfortably on the back of the hand support seat 1 and the fingers are accurately placed on the corresponding finger bending plates 2, the first rotating disk 19 located inside the one side support plate 18 starts to rotate, and when the first rotating disk 19 starts to rotate, the torque generated by it can drive the hand placed on the plurality of finger bending plates 2 corresponding to the five fingers and the back of the hand support seat 1 to twist, thereby achieving the effect of rehabilitation exercise on the patient's wrist.

[0031] The expansion groove 16 provides a stable track and support for the rotation of the rotating block 17, ensuring the smoothness and accuracy of the rotation, so that the fingers can expand in the expected direction and angle, and the first turntable 19 is arranged in the support plate 18 on one side. Its rotation can apply torque to the wrist area, making wrist exercise more targeted and improving the rehabilitation effect.

[0032] An adjustable orthopedic rehabilitation exercise device is further optimized, specifically, as Figure 4 As shown, the expansion mechanism also includes an electric slide rail 20, a slider 21 and a connecting rod 22. The electric slide rail 20 is fixed on the first turntable 19 and is slidably connected to the four sliders 21. The connecting rod 22 is fixed on the slider 21 and is connected to multiple protective plates 4. A driving motor 23 whose output shaft is fixedly connected to the first turntable 19 is also fixed on one side support plate 18, and a second turntable 24 fixed to the back of the hand support seat 1 is also rotatable on the other side support plate 18; start the driving motor 23, and its output shaft drives the first turntable 19 to rotate, thereby driving the electric slide rail 20 to rotate. When the electric slide rail 20 is working, four sliders 21 in different positions slide on it respectively. Due to the different positions of the sliders 21, the sliding of the sliders 21 drives the protective plate 4 connected thereto to produce different movement amplitudes and directions through the connecting rod 22. This differential movement can perform precise expansion control for each finger respectively, so that each finger can receive personalized rehabilitation training. At the same time, the rotation of the first turntable 19 and the cooperation of the second turntable 24 enable the entire expansion mechanism to operate more stably and coordinately to adapt to the hand conditions and rehabilitation needs of different patients.

[0033] Through the four sliders 21 with different positions on the electric slide rail 20, expansion force is provided for independent expansion of each finger, and a precise and flexible control method is provided for the position adjustment of the protective plate 4 and the finger bending plate 2. The connecting rod 22 effectively transmits the movement of the slider 21 to the protective plate 4, ensuring the transmission of force and consistency of movement.

[0034] Further, such as Figure 4 As shown, one side of the multiple finger bending plates 2 is fixedly connected with a rotating rod 201, and the other side of the finger bending plate 2 is hinged through the rotating rod 201. Both end surfaces of the rotating rod 201 are sleeved with torsion springs 202, and both ends of the torsion spring 202 are fixedly connected to the multiple finger bending plates 2; when the fingers are stretched by the silicone hose 9, the finger bending plates 2 are unfolded accordingly, driving the rotating rod 201 to rotate. At this time, the torsion springs 202 sleeved on the two end surfaces of the rotating rod 201 are twisted and force is stored. When the external force disappears, the torsion springs 202 release the stored energy, driving the rotating rod 201 to rotate in the opposite direction, thereby resetting the finger bending plate 2, assisting the fingers to resume the bending state, and realizing the repeated gripping and stretching movements of the fingers.

[0035] The rotating rod 201 provides stable rotational support for the coordinated movement of the finger bending plate 2. The setting of the torsion spring 202 cleverly utilizes its elastic potential energy, stores energy when the finger is extended, and releases it when needed, assisting the natural bending of the finger, reducing the patient's own effort, and making rehabilitation training easier and more efficient.

[0036] An adjustable orthopedic rehabilitation exercise device is further optimized, specifically, as Figure 1-Figure 4 As shown, the surface of the protective plate 4 is sleeved with a positioning plate 203, and a magnetic plate 204 connected to the protective plate 4 by magnetic attraction is symmetrically fixed on the surface of the positioning plate 203, and a protective pad 205 that fits the silicone hose 9 is fixed on the top surface of the inner wall of the positioning plate 203; the positioning plate 203 is sleeved on the surface of the protective plate 4 by the magnetic attraction of the magnetic plate 204. When the silicone hose 9 contacts the protective plate 4, the protective pad 205 on the top surface of the inner wall of the positioning plate 203 will fit the silicone hose 9, thereby protecting and fixing the silicone hose 9.

[0037] The positioning plate 203 can be conveniently installed on the protective plate 4 through the magnetic plate 204. The cooperation between the positioning plate 203 and the protective pad 205 can effectively fix the silicone hose 9 to prevent it from shifting or shaking during use, thereby ensuring the stability and effectiveness of rehabilitation training.

[0038] Further, such as Figure 4As shown, the bottom surface of the back of hand support seat 1 is magnetically connected to a limit plate 10, and the surface of the limit plate 10 is provided with an arc-shaped placement groove corresponding to the silicone hose 9; the limit plate 10 is adsorbed on the bottom surface of the back of hand support seat 1 by magnetic force. When in use, the silicone hose 9 is placed in the arc-shaped placement groove provided on the surface of the limit plate 10, and the arc-shaped placement groove provides a specific position for the silicone hose 9, which plays a role in limiting and arranging the direction of the silicone hose 9.

[0039] The magnetic connection makes it very convenient to connect and separate the limit plate 10 and the back of the hand support seat 1, and it is convenient to install and disassemble according to needs. The arc placement groove can effectively position and restrain the silicone hose 9 to avoid it being messy during use, ensuring the cleanliness and order of the equipment.

[0040] Further, such as Figure 1-Figure 8 As shown, the number of finger bending plates 2 is fifteen, and the finger bending plates 2 are divided into five groups of three; the fifteen finger bending plates 2 are divided into five groups, with three in each group. During hand rehabilitation training, each group of finger bending plates 2 can work together to correspond to different parts of the fingers, thereby more accurately controlling the movement of the fingers and realizing the bending, extension and various complex movements of the fingers.

[0041] The design of three finger bending plates 2 in each group better adapts to the physiological structure of the fingers, can evenly distribute force, reduce local pressure, and lower the risk of injury. The sufficient number of fifteen finger bending plates 2 ensures comprehensive coverage of all joints and parts of the fingers, without missing any area that needs rehabilitation.
