Description

Technical Field

[0001] This utility model belongs to the technical field of limb rehabilitation training equipment, specifically relating to a neurosurgical rehabilitation limb training device. Background Technology

[0002] In neurosurgery, patients with limb dysfunction due to damage to the nervous system need limb rehabilitation training after treatment. Through training, the patient's limb motor ability, balance ability, coordination ability, etc. can be gradually improved, so as to help the patient restore the damaged limb function and improve the ability to take care of themselves and the quality of life. In the rehabilitation process, the main training focuses on motor function (arm raising, leg raising, hand grasping, etc.), balance and coordination (standing and walking, hand-eye coordination and hand-foot coordination, etc.), gait, etc.

[0003] When patients undergo hand grasping rehabilitation training, they generally use grasping equipment such as gripping balls, gripping ball rings, and finger strength grasping devices with elastic bands to train finger strength. However, the above-mentioned grasping training equipment mainly relies on the bending of the fingers to achieve the training effect. The fingers only bend in one direction, such as bending at the palm position. It can only train the bending strength of the fingers, but cannot carry out the rotational movement of the fingers to control the rotation of objects, which is a shortcoming.

[0004] Existing hand rehabilitation training for patients with neurosurgical hand limb disorders lacks a limb training device for training hand rotation movements. Therefore, this application proposes a neurosurgical rehabilitation limb training device. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 4This utility model provides a technical solution: a neurosurgical rehabilitation limb training device, including a fixing frame, a fixing round shell 11, a connecting rod 12 with one end screwed to the fixing round shell 11, an adjusting screw 13 with the connecting rod 12 screwed to the connecting rod 12, and a limiting wristband 14 with one end glued to the adjusting screw 13. A first Velcro 141 is glued to the outer surface of the limiting wristband 14, and a binding strap 142 is fixedly connected to one end of the limiting wristband 14. In use, the limiting wristband 14 fits against the patient's wrist, and the binding strap 142, after wrapping around the patient's wrist, adheres to the first Velcro 141, thus stabilizing the limiting wristband 14, thereby stabilizing the connecting rod 12 and the fixing round shell 11, and allowing the palm support shell 4 to contact the palm. The connecting rod 12 is threadedly connected to the fixed circular shell 11, which can change the depth of the connecting rod 12 inserted into the fixed circular shell 11. The adjusting screw 13 is threadedly connected to the connecting rod 12, which can change the distance between the limiting wristband 14 and the connecting rod 12, suitable for different patients. The hand and limb training component includes a stabilizing ring 2 fixedly connected to the fixed circular shell 11, a stabilizing block 71 connected to the inner surface of the stabilizing ring 2, a stabilizing ring 72 passing through the symmetrically distributed stabilizing blocks 71, a return spring 73 sleeved on the outside of the stabilizing ring 72, and a pressing member 74 installed between adjacent return springs 73. The return spring 73 is limited by the stabilizing ring 72. When the return spring 73 is compressed by the pressing member 74, the pressing member 74 is subjected to the return elastic force of the return spring 73.

[0027] A rotating cylinder 3 with one end sealed is connected to a fixed cylindrical shell 11. A fixed shaft 31 passes through the center of the sealed end of the rotating cylinder 3. The fixed shaft 31 passes through one end of the rotating cylinder 3 and is connected to the fixed cylindrical shell 11 by a threaded connection, thereby limiting the rotating cylinder 3. In addition, the rotating cylinder 3 rotates around the fixed shaft 31. The extrusion member 74 is connected to the rotating cylinder 3 to form an integral structure. The extrusion member 74 and the rotating cylinder 3 rotate in the same direction.

[0028] The palm support shell 4 is fixed to the rotating cylinder 3 by a hand-tightening screw. The patient's palm fits against the palm support shell 4, and the fingers contact the outer surface of the palm support shell 4. When the patient rotates the palm support shell 4, the palm support shell 4, the rotating cylinder 3, and the squeezing member 74 are considered as a whole and rotate. At this time, the rotating squeezing member 74 will squeeze the return spring 73. The return spring 73 also generates an elastic force to prevent the palm support shell 4, the rotating cylinder 3, and the squeezing member 74 from rotating. The patient's fingers need to use a certain amount of force to complete the rotation process, and a certain amount of force control is also required to make the palm support shell 4 slowly rotate and return to its original position. Repeating the rotation movement can achieve the effect of training the finger rotation movement.

[0029] The tension component includes a rubber sleeve 5 fitted on the outside of the fixed circular shell 11, a rubber band 6 with one end connected to the outer surface of the rubber sleeve 5, and a rubber finger sleeve 61 connected to the other end of the rubber band 6. The finger can pass through the corresponding rubber finger sleeve 61. When the patient controls the palm support shell 4 to rotate with their finger, the rubber band 6 will exert a tension on the patient's finger, which will have the effect of training the patient's finger strength.

[0030] In this embodiment, the interior of the fixed circular shell 11 is hollow, and an external thread is provided on the outer surface of one end of the connecting rod 12, which facilitates the spiral insertion of one end of the connecting rod 12 into the interior of the fixed circular shell 11. The adjusting screw 13 is perpendicular to the connecting rod 12. The limiting wristband 14 is in the shape of a semi-circular ring and is made of rubber material, which has the ability to deform and is convenient to wear on the patient's wrist.

[0031] In this embodiment, a second Velcro strap, which is attached to the first Velcro strap 141, is sewn onto the end of the binding strap 142 away from the limiting wristband 14, and the binding strap 142 is firmly attached to the limiting wristband 14.

[0032] In this embodiment, the fixed shaft 31 includes a limiting post and a connecting post. The outer surface of the connecting post away from the limiting post is provided with an external thread. The fixed shaft 31 passes through one end of the rotating cylinder 3 and is connected to the fixed shell 11 by threaded engagement, thereby achieving the purpose of limiting the rotating cylinder 3.

[0033] In this embodiment, the rubber strips 6 on the outer side of the rubber sleeve 5 are evenly distributed. The rubber strips 6 are integrally injection molded with the rubber sleeve 5 and the rubber finger sleeve 61. The rubber strips 6 are firmly connected with the rubber sleeve 5 and the rubber finger sleeve 61. The rubber sleeve 5 and the fixed round shell 11 are separate structures, and the damaged rubber sleeve 5 can be replaced.

[0034] In this embodiment, the extrusion member 74 is slidably connected to the stabilizing ring 72, one end of the return spring 73 is welded to the stabilizing block 71, and the other end of the return spring 73 is in sliding contact with the surface of the extrusion member 74. When the extrusion member 74 rotates instantaneously in the direction a, the extrusion member 74 extrudes the return spring 73 on one side, and the return spring 73 on the other side is separated from the extrusion member 74. The extrusion member 74 is subjected to the elastic force of the return spring 73.

[0035] In this embodiment, the extrusion member 74 includes an annular portion and a cylindrical portion. The return spring 73 contacts the annular portion, and the cylindrical portion of the extrusion member 74 is fixed to the rotating cylinder 3 by screws. The extrusion member 74 can compress the return spring 73.

[0036] Working principle and usage process of this utility model:

[0037] When using this device for finger rehabilitation training, first adjust the positions of the connecting rod 12 and the adjusting screw 13 so that the palm support shell 4 fits against the palm and the limiting wristband 14 contacts the patient's wrist. After the binding strap 142 is wrapped around the patient's wrist, it is attached to the first Velcro 141 to keep the limiting wristband 14 stable, thereby keeping the connecting rod 12 and the fixed round shell 11 stable, and keeping the palm support shell 4 in stable contact with the palm.

[0038] Afterwards, the fingers pass through the corresponding rubber finger sleeves 61. When the patient controls the palm support shell 4 to rotate with their fingers, the rubber band 6 will exert a pulling force on the patient's fingers, which will help train the patient's finger strength.

[0039] When the patient controls the palm support shell 4 to rotate clockwise in direction a, the palm support shell 4, the rotating cylinder 3, and the pressing component 74 are considered as a whole and rotate. At this time, the rotating pressing component 74 will compress the return spring 73, and the return spring 73 will also generate an elastic force to prevent the palm support shell 4, the rotating cylinder 3, and the pressing component 74 from rotating. The patient needs to use a certain amount of force to complete the rotation process, and also needs to control the force to make the palm support shell 4 slowly rotate and return to its original position. Repeating the rotation movement can achieve the effect of training the finger rotation movement. When the patient controls the palm support shell 4 to rotate counterclockwise in direction b, the training of controlling the force of finger rotation can be achieved.

[0040] In summary, this invention provides a limb training device for training hand rotational movements. When the patient's fingers pass through the corresponding rubber finger sleeves 61 and the palm support shell 4 is rotated, the rubber band 6 exerts a pulling force on the patient's fingers, thus training the strength of the patient's fingers. In addition, the compressed return spring 73 also generates an elastic force to prevent the palm support shell 4, the rotating cylinder 3, and the squeezing member 74 from rotating. The patient's fingers need to use a certain amount of force to complete the rotation process, and a certain amount of force control is also required to make the palm support shell 4 slowly rotate and return to its original position. Repeating the rotational movement can achieve the effect of training finger rotational movements.

[0041] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
