Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically, to a rehabilitation exercise device specialized for hand surgery. Background Art

[0002] As the most delicate motor organ of the human body, the hand has a highly complex anatomical structure, including 27 bones, 24 tendons, and a rich network of nerves and blood vessels, playing a core role in composite functions such as grasping, pinching, and sensing. According to statistics, hand injuries account for more than 20% of all body traumas. Moreover, with the acceleration of industrialization and the aging of the population, cases of traumatic fractures, tenosynovitis, peripheral nerve compression, and postoperative dysfunction are showing a significant growth trend. Clinical studies have shown that the golden period for hand function recovery is 6 - 8 weeks after injury. Without scientific and systematic rehabilitation training, it may lead to joint stiffness, muscle atrophy, and permanent loss of function, seriously affecting the quality of life of patients.

[0003] Current hand rehabilitation devices generally have the following limitations: Traditional stent - like devices can only provide static fixation and are difficult to achieve dynamic function remodeling; Commercially available rehabilitation instruments generally have problems such as poor adaptability and single training modes, and are difficult to simulate the fine - movement requirements in real - life scenarios; Some electric devices, although having passive movement functions, lack a biomechanical feedback mechanism and cannot intelligently adjust the training intensity according to the patient's recovery progress. In a patent with the title "A Rehabilitation Exercise Device for Hand Surgery" and the publication number: CN109998858B, it is proposed that the thumb is very important for everyone and has a high usage frequency. However, a person's thumb is also prone to injury. Especially for a fractured thumb during the late rehabilitation period, it needs to be exercised to restore the flexibility of the thumb and the functional position of the thumb joint. However, currently in hand surgery, there is a lack of a rehabilitation exercise device for the patient's thumb. It uses a spherical joint and a joint sleeve to assist the thumb in exercising to restore the flexibility of the patient's thumb and the functional position of the thumb joint. However, during the overall training process of the thumb, it can only provide active - assisted exercise for the thumb and cannot perform autonomous resistance exercise. Therefore, this application proposes a rehabilitation exercise device specialized for hand surgery. Summary of the Invention

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1. As Figure 1As shown in the figure, a rehabilitation exercise device dedicated to hand surgery in this application includes an upper support plate 101. A positioning column 102 is fixedly connected to the upper support plate 101. A driving motor 103 is fixedly connected to the positioning column 102. A coupling swing structure is installed at the end of the output shaft of the driving motor 103. A rear hemispherical body 113 is fixedly connected to the end of the coupling swing structure away from the driving motor 103. An installation pipe 118 is fixedly connected to the upper support plate 101. A spherical shell member 110 is fixedly connected to the bottom of the installation pipe 118. A front magnetic hemispherical body 114 is placed inside the spherical shell member 110. An extension assembly 111 is fixedly connected to the outside of the front magnetic hemispherical body 114. A thumb cover 112 is installed at the end of the extension assembly 111 away from the spherical shell member 110. A moving groove 115 is opened inside the rear hemispherical body 113. A wool surface insertion hole 117 is opened inside the front magnetic hemispherical body 114. A moving block 116 is slidably connected inside the moving groove 115.

[0020] Specifically, during the use process, the patient inserts the thumb into the inside of the thumb cover 112, and starts the driving motor 103 to drive the coupling swing structure to rotate. During the rotation of the coupling swing structure, the rear hemispherical body 113 can be driven to swing. During the swing of the rear hemispherical body 113, the front magnetic hemispherical body 114 will be driven to swing. During the swing of the front magnetic hemispherical body 114, the thumb cover 112 will be driven to swing through the extension assembly 111, thereby driving the thumb located inside the thumb cover 112 to swing.

[0021] Further, after the patient undergoes passive training, the patient needs to perform active cycling. However, during active training, the force that the patient's thumb can provide is insufficient. If the patient needs to insert into the thumb cover 112 to provide a certain resistance, the patient may not be able to drive the thumb cover 112, the extension component 111, the rear hemisphere 113, the front magnetic hemisphere 114, and the rear shaft rocking structure through the active rotation of the thumb. The connection between multiple components will increase the resistance during the patient's active training. In this case of constant resistance, it cannot assist the patient's training during the initial training. Therefore, during the patient's initial active training process, the front magnetic hemisphere 114 and the moving block 116 can be turned on, so that a repulsive force is generated between the front magnetic hemisphere 114 and the moving block 116. When a repulsive force is generated between the front magnetic hemisphere 114 and the moving block 116, it can push the front magnetic hemisphere 114 and the rear hemisphere 113 to separate, and push the moving block 116 back into the interior of the moving groove 115. After pushing the moving block 116 back into the interior of the moving groove 115, a separated state where the rear hemisphere 113 and the front magnetic hemisphere 114 do not interfere with each other will be formed. Thus, when the patient inserts the thumb into the thumb cover 112 for active training, the training of the thumb only needs to drive the weights of the thumb cover 112, the extension component 111, and the front magnetic hemisphere 114. Overall, the weight during the active cycling of the thumb is reduced, which can assist in training and avoid the situation where training cannot be carried out due to excessive weight.

[0022] As Figure 6 shown, the extension component 111 includes a guide tube 400. One end of the guide tube 400 is fixedly connected to the outside of the front magnetic hemisphere 114. An inner layer extension tube 402 is slidably connected to the inside of the guide tube 400. A positioning hole is formed in the outside of the guide tube 400, and a positioning bolt 401 is inserted into the positioning hole. One end of the inner layer extension tube 402 away from the guide tube 400 is fixedly connected to the outside of the thumb cover 112.

[0023] Specifically, during the patient's use process, the inner layer extension tube 402 can be pulled out of the inside of the guide tube 400, and the inner layer extension tube 402 can be fixed by the positioning bolt 401, so as to overall extend the distance between the thumb cover 112 and the front magnetic hemisphere 114, thereby adjusting the overall swing amplitude of the patient's thumb.

[0024] As Figure 1 - and Figure 2As shown in the figure, the shaft coupling swing structure includes a coupling 104, which is fixedly connected to the output shaft of the driving motor 103. A positioning plate 105 is fixedly connected to the upper support plate 101. A rotating circular plate 106 is rotatably connected to the positioning plate 105 through a rotating shaft. One end of the coupling 104 away from the driving motor 103 is fixedly connected to the rotating shaft of the rotating circular plate 106. An I-shaped rotating connecting shaft 107 is rotatably connected to the outside of the rotating circular plate 106 through a rotating shaft. One end of the I-shaped rotating connecting shaft 107 away from the rotating circular plate 106 is connected to a connecting rod 108. One end of the connecting rod 108 away from the I-shaped rotating connecting shaft 107 is fixedly connected to a rubber column 109. One end of the rubber column 109 away from the connecting rod 108 is fixedly connected to the outside of the rear hemisphere 113.

[0025] Specifically, in the shaft coupling swing structure, when the driving motor 103 rotates, it will drive the coupling 104 to rotate. The rotation of the coupling 104 will drive the rotating circular plate 106 to rotate. During the rotation of the rotating circular plate 106, it will drive the I-shaped rotating connecting shaft 107 to rotate around the rotating circular plate 106. The rotation of the I-shaped rotating connecting shaft 107 will drive the connecting rod 108 to swing and rotate. The rotation of the connecting rod 108 will drive the rubber column 109 and the rear hemisphere 113 to rotate, and overall drive the front magnetic hemisphere 114 and the thumb cover 112 to swing and rotate to assist the patient in exercising the thumb.

[0026] As Figure 2 As shown in the figure, a bottom support plate 100 is fixedly connected below the upper support plate 101. A placement cavity is formed between the bottom support plate 100 and the upper support plate 101. A chute 803 is opened on the upper support plate 101. A sliding seat 801 is slidably connected inside the chute 803. A placement seat 802 is fixedly connected to the top of the sliding seat 801. A sliding rod 800 is fixedly connected inside the placement cavity. The sliding rod 800 penetrates the outer wall of the sliding seat 801, and the sliding seat 801 is slidably connected to the outside of the sliding rod 800.

[0027] Specifically, during use, when the patient places the thumb into the inside of the thumb cover 112, there is a need for a position to place the arm and hand. When the patient needs to support the arm and hand, the arm or hand can be placed on the placement seat 802. After placing the arm and hand on the placement seat 802, the placement seat 802 can be pushed to drive the sliding seat 801 to slide back and forth on the sliding rod 800, thereby adjusting the position of the placement seat 802 on the upper support plate 101. The sliding seat 801 can be guided through the chute 803 to ensure that the whole moves inside the chute 803, facilitating the support effect on the human arm and hand.

[0028] As Figures 6 - 7As shown, rough hair layers 700 are bonded to the outer wall of the moving block 116 and the inner wall of the rough surface socket 117. A blocking outer edge is integrally formed at the internal outlet of the moving groove 115. A blocking plate 701 is fixedly connected to one side of the moving block 116 close to the moving groove 115.

[0029] Specifically, when it is necessary to connect the rear hemisphere 113 and the front magnetic hemisphere 114, the front magnetic hemisphere 114 can be activated to adsorb the rear hemisphere 113 and the moving block 116. When the front magnetic hemisphere 114 adsorbs the moving block 116, the moving block 116 can be moved into the rough surface socket 117. When the moving block 116 moves into the rough surface socket 117, the connection between the rear hemisphere 113 and the front magnetic hemisphere 114 can be completed. And when the moving block 116 enters the rough surface socket 117, the rough hair layers 700 on the outer wall of the moving block 116 and the inner wall of the rough surface socket 117 can generate a certain frictional force, thus preventing the rear hemisphere 113 and the front magnetic hemisphere 114 from separating randomly.

[0030] The technical solution in the embodiment of the present application above has at least the following technical effects or advantages: Compared with the prior art, in this embodiment, when the rear hemisphere 113 and the front magnetic hemisphere 114 are separated, the patient can perform active training during the thumb training process, and during the assisted active training, no great resistance will be given to the patient. Overall, the switching between active and passive training is achieved, and when the patient performs active training, no great resistance will be generated to cause the patient to be unable to perform appropriate training.

[0031] Embodiment 2: Considering that when the patient performs active training, although the active training can be completed through the separated front magnetic hemisphere 114 and the thumb cover 112, the resistance during the active training process is constant and cannot be adjusted according to the patient's rehabilitation situation. To solve the above technical problems, the present application proposes the following technical solution: As Figure 3 shown, a plurality of placement grooves are integrally formed on the outer surface of the front magnetic hemisphere 114. A first electromagnetic suction plate 200 is installed in each of the plurality of placement grooves. A plurality of second electromagnetic suction plates 201 are integrally formed on the inner wall surface of the spherical shell member 110. The positions of the plurality of second electromagnetic suction plates 201 correspond to those of the plurality of first electromagnetic suction plates 200.

[0032] Specifically, during the use process, when the rear hemisphere 113 and the front magnetic hemisphere 114 are integrally connected, the thumb cover 112 can be driven to rotate by driving the driving motor 103, thereby assisting in the exercise of the human finger. And during the exercise process, the overall rotation force is constant. Therefore, power can be supplied to multiple first electromagnetic suction plates 200 and second electromagnetic suction plates 201 at the same time. When power is supplied to multiple first electromagnetic suction plates 200 and second electromagnetic suction plates 201, a certain attraction and repulsion force will be generated between multiple first electromagnetic suction plates 200 and second electromagnetic suction plates 201. When a repulsive force is generated between multiple first electromagnetic suction plates 200 and second electromagnetic suction plates 201, it can provide resistance to the movement of the patient, and the power supply to the first electromagnetic suction plates 200 and second electromagnetic suction plates 201 can be adjusted according to the different degrees of the patient's recovery. When the patient needs a greater training resistance, the power supply to the first electromagnetic suction plates 200 and second electromagnetic suction plates 201 is increased. When a training with a smaller resistance is needed, only the corresponding power supply to the first electromagnetic suction plates 200 and second electromagnetic suction plates 201 needs to be reduced.

[0033] As Figure 3 shown, the spherical shell member 110 includes a left hemispherical shell 1101 and a right hemispherical shell 1102. A plurality of insertion rods 1104 are fixedly connected to one side of the left hemispherical shell 1101 adjacent to the right hemispherical shell 1102. A plurality of connection holes 1103 are formed on the side of the right hemispherical shell 1102 close to the left hemispherical shell 1101. Insertion holes matching the outer wall diameter of the installation pipe 118 are formed at the bottoms of the left hemispherical shell 1101 and the right hemispherical shell 1102. The insertion rods 1104 are inserted into the interiors of the connection holes 1103, and the left hemispherical shell 1101 and the right hemispherical shell 1102 are inserted and clamped with the installation pipe 118 through the insertion holes.

[0034] Specifically, during the use process, the left hemispherical shell 1101 and the right hemispherical shell 1102 together form the spherical shell member 110, which is convenient for the installation and maintenance of the second electromagnetic suction plates 201 and the first electromagnetic suction plates 200. The left hemispherical shell 1101 and the right hemispherical shell 1102 are spliced by inserting the insertion rods 1104 into the interiors of the connection holes 1103. At the same time, when the left hemispherical shell 1101 and the right hemispherical shell 1102 are spliced, the semi-circular insertion holes formed outside the left hemispherical shell 1101 and the right hemispherical shell 1102 can be attached to the outside of the installation pipe 118 during the splicing process, so that the left hemispherical shell 1101 and the right hemispherical shell 1102 are connected to the installation pipe 118 together during the splicing process.

[0035] The technical solutions in the embodiments of the present application described above have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, through the power supply between multiple first electromagnetic suction plates 200 and multiple second electromagnetic suction plates 201, different mutual adsorption forces and mutual repulsive forces can be generated between the multiple first electromagnetic suction plates 200 and the second electromagnetic suction plates 201. During the process of generating different degrees of mutual repulsive forces, a certain resistance can be generated when the rear hemisphere 113 and the front magnetic hemisphere 114 rotate inside the left hemisphere shell 1101 and the right hemisphere shell 1102, thereby assisting the patient in performing adjustable autonomous rehabilitation resistance training.

[0036] Embodiment 3. Considering that during the thumb training process, patients not only need to perform reciprocating rotation training, but in the rehabilitation process of some patients, they do not need to perform rotational training on the thumb, but need to perform back-and-forth reciprocating training in one direction. To solve the above technical problems, the present application proposes the following technical solutions, specifically: As Figures 3 - 6 shown, multiple first electromagnetic suction plates 200 and second electromagnetic suction plates 201 are used to provide repulsive forces to the rear hemisphere 113 and the front magnetic hemisphere 114 when the rear hemisphere 113 and the front magnetic hemisphere 114 rotate, and by providing repulsive forces to the rear hemisphere 113 and the front magnetic hemisphere 114, the rear hemisphere 113 and the front magnetic hemisphere 114 can be pushed to rotate in different directions.

[0037] Specifically, the arrangement of the second electromagnetic suction plates 201 and the first electromagnetic suction plates 200 is circumferentially arranged around the inner wall of the spherical shell member 110 and the outer wall of the front magnetic hemisphere 114. When the patient needs to move the thumb back and forth in a certain specified direction for training, only the first electromagnetic suction plates 200 and the second electromagnetic suction plates 201 parallel to a certain direction need to be activated to generate mutual adsorption. When the first electromagnetic suction plates 200 and the second electromagnetic suction plates 201 in a certain direction generate adsorption, the front magnetic hemisphere 114 can be driven to rotate in the specified direction. When the thumb needs to be returned to the original position, only the first electromagnetic suction plates 200 and the second electromagnetic suction plates 201 in the opposite direction need to be activated to generate mutual adsorption to adsorb the front magnetic hemisphere 114 back to the original position.

[0038] The technical solutions in the embodiments of the present application described above have at least the following technical effects or advantages: Compared with Embodiment 2, in this embodiment, again through the mutual adsorption and mutual repulsion generated between the multiple first electromagnetic suction plates 200 and the second electromagnetic suction plates 201, the front magnetic hemisphere 114 can be adsorbed or pushed to rotate and move inside the spherical shell member 110, realizing multi-angle reciprocating exercise and movement of the patient.

[0039] Embodiment 4: Considering that the direction between the front magnetic hemisphere 114 and the spherical shell 110 can be adjusted by the adsorption and repulsion between the first electromagnetic suction plate 200 and the second electromagnetic suction plate 201, there is a gap between the front magnetic hemisphere 114 and the spherical shell 110. Once the adsorption between the first electromagnetic suction plate 200 and the second electromagnetic suction plate 201 is lost, the front magnetic hemisphere 114 may be driven by the front thumb cover 112 to change its direction again under the force of gravity, thereby causing the patient to have a secondary directional displacement when performing reciprocating exercises, and it is impossible to achieve reciprocating displacement in a parallel direction. In view of the above technical problems, the present application proposes the following technical solutions to solve the above technical problems, specifically: like Figures 2 - 6 As shown, a micro air pump 300 is fixedly connected to the bottom of the upper support plate 101, and the air outlet of the micro air pump 300 is connected to a multi-way gas delivery tube 301. The air outlet of the multi-way gas delivery tube 301 passes through the outer wall of the upper support plate 101, and the inner wall of the multiple placement grooves is integrally formed with an expansion air bag 302. The first electromagnetic suction plate 200 is fixedly connected to the expansion air bag 302 on one side close to the expansion air bag 302, and the multiple air outlets of the multi-way gas delivery tube 301 all pass through the mounting tube 118 and are respectively connected to the multiple expansion air bags 302.

[0040] Specifically, during use and during rehabilitation training, the staff can start the micro air pump 300. When the micro air pump 300 is started, the gas can be delivered into the multi-way gas delivery tube 301. When the gas is delivered into the multi-way gas delivery tube 301, the multiple expansion air bags 302 can be expanded. When the expansion air bags 302 are expanded, the first electromagnetic suction plate 200 can be driven to move out of the placement groove and gradually fit to the left hemispherical shell 1101 and the right hemispherical shell 110. 2, when the first electromagnetic suction plate 200 is driven to gradually approach the inner walls of the left hemispherical shell 1101 and the right hemispherical shell 1102, a phenomenon of extrusion and clamping can be formed between the first electromagnetic suction plate 200 and the left hemispherical shell 1101 and the right hemispherical shell 1102, so that even when the magnetic adsorption force and repulsion force are completely lost between the first electromagnetic suction plate 200 and the second electromagnetic suction plate 201, the front magnetic hemisphere 114 can still ensure stability inside the left hemispherical shell 1101 and the right hemispherical shell 1102, and will not change position at will.

[0041] like Figure 6 As shown, a moving tube 600 is slidably connected to the inner center of the thumb cover 112, one end of the moving tube 600 is slidably connected to the inside of the inner extension tube 402, and the other end of the moving tube 600 is fixedly connected to the third electromagnetic suction plate 601, and an elastic pad 500 is fixedly connected to the inner wall of the thumb cover 112, and the inside of the elastic pad 500 is fixedly connected to the fourth electromagnetic suction plate 602.

[0042] Specifically, during the exercise of the thumb, not only the metacarpal joint connected to the thumb needs to be exercised, but sometimes the proximal phalanx of the thumb also needs to be exercised. During the exercise of the proximal phalanx, the third electromagnetic suction plate 601 and the fourth electromagnetic suction plate 602 can be simultaneously activated to drive the moving tube 600 to slide inside the inner extension tube 402. Moreover, the third electromagnetic suction plate 601 will drive the moving tube 600 to gradually approach the fourth electromagnetic suction plate 602. When gradually approaching the fourth electromagnetic suction plate 602, the third electromagnetic suction plate 601 can push the proximal phalanx of the human thumb to bend, thereby performing a bending exercise on the proximal phalanx of the thumb.

[0043] As Figure 6 shown, a plurality of elastic rolling balls 501 are rotatably connected inside the elastic cushion 500.

[0044] Specifically, through the setting of the elastic rolling balls 501, when the patient's thumb is inserted into the thumb cover 112 and is located at the middle position of the plurality of elastic rolling balls 501, the plurality of elastic rolling balls 501 can squeeze and limit the thumb. And when the thumb performs a rotation training, the elastic rolling balls 501 will rotate, which can not only massage the thumb, but also avoid the phenomenon that the thumb is overly squeezed to cause pain, and can further assist the thumb to rotate inside the thumb cover 112 to assist the exercise of the thumb.

[0045] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages: Compared with Embodiment 3, in this embodiment, when the micro air pump 300 continuously injects gas into the expansion airbag 302, the expansion airbag 302 can be expanded. When the expansion airbag 302 is expanded, it can fit with the inner walls of the left hemisphere shell 1101 and the right hemisphere shell 1102. When the expansion airbag 302 drives the first electromagnetic suction plate 200 to fit and squeeze between the left hemisphere shell 1101 and the right hemisphere shell 1102, even when the magnetic adsorption force and repulsive force between the first electromagnetic suction plate 200 and the second electromagnetic suction plate 201 are completely lost, the front magnetic hemisphere 114 can still ensure stability inside the left hemisphere shell 1101 and the right hemisphere shell 1102 and will not randomly change its position.

[0046] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
