Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bone and joint movement bionic rehabilitation training device. Background Technology

[0002] Rehabilitation medicine is an applied medical discipline that studies the rehabilitation of patients with injuries and illnesses. It uses various methods such as physical therapy, exercise therapy, and daily living training to help patients recover to the maximum extent possible, enabling them to regain their ability to live independently, work, and perform tasks, thus laying the foundation for their reintegration into society. Osteoarthritis is a common and frequently occurring disease in clinical practice, and its prevalence increases with age. Patients with osteoarthritis may experience difficulty or pain when standing or walking. Therefore, it is necessary to carry out osteoarthritis rehabilitation exercises for these patients, which is why specialized rehabilitation training devices are used.

[0003] Chinese Patent Announcement No.: CN220193482U, a bionic rehabilitation training device for bone and joint movement. This utility model mounts a seat on a base plate using a hydraulic press. The height of the base plate is adjusted by the hydraulic press. At the same time, an arc-shaped guide rail and a placement frame are movably mounted on the base plate using an adjustable base. Then, an adjustable drive device is used to adjust the position of the arc-shaped guide rail and the placement frame to meet the height adjustment of the seat and the distance between the seat and the arc-shaped guide rail and the placement frame, so that it can be used by patients of different heights, greatly improving the practicality of the device.

[0004] The aforementioned existing technology has the following problems: when patients perform leg training, their leg movement trajectory can only move back and forth along the arc-shaped groove, and the movement trajectory is consistent. Since the movement trajectory of the arc-shaped groove may limit the natural range of motion of the joint, the joint needs to perform multiple angles and directions of movement during normal gait and movement. If the training is limited to the arc-shaped trajectory, the flexibility of the joint may be restricted, affecting the patient's daily life and rehabilitation training effect. Utility Model Content

[0023] 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.

[0024] Please see Figure 1 This embodiment provides a bone and joint movement bionic rehabilitation training device, which is used to increase the range of motion of the joint and enhance the multi-angle and multi-directional training of the joint.

[0025] Specifically, it includes a support frame 1, a seat 2, and two leg training mechanisms 3; the seat 2 is installed on the support frame 1, and the two leg training mechanisms 3 are symmetrically arranged on the front side of the support frame 1 to perform rehabilitation training on the patient's leg joints.

[0026] In practical application, the patient's two legs are connected to two leg training mechanisms 3 respectively. The operation of the two leg training mechanisms 3 drives the joints of the patient's two legs to move, thereby realizing the bionic rehabilitation training of the legs.

[0027] Please see Figure 2-3 In order to achieve biomimetic rehabilitation training of the leg joint, the leg training mechanism 3 in this embodiment includes a connecting arm 301 hinged to the front side of the support frame 1 via a hinge shaft, and the connecting arm 301 can rotate in the XY plane; the end of the connecting arm 301 away from the support frame 1 is hinged to a thigh support arm 302 via a hinge shaft, and a vertical plate 303 is installed at the bottom of the connecting arm 301. The side of the vertical plate 303 facing the thigh support arm 302 is hinged to a first cylinder 304 via a hinge shaft. The output end of the first cylinder 304 is hinged to the thigh support arm 302 via a hinge shaft to drive the thigh support arm 302 to rotate in the ZX plane.

[0028] In actual use, the patient's two legs are connected to two thigh support arms 302 respectively. The extension and retraction of the output ends of the two first cylinders 304 drive the thigh support arms 302 and the patient's thighs to swing on the ZX plane, thereby realizing rehabilitation training for the patient's thigh joints.

[0029] In addition to this, in order to further extend the range of motion of the thigh support arm 302 and improve the angle and direction of rehabilitation training, in this embodiment, a second cylinder 305 is hinged to the front side of the support frame 1 via a hinge shaft. The output end of the second cylinder 305 is hinged to the connecting arm 301 via a hinge shaft to drive the connecting arm 301 to rotate in the XY plane.

[0030] In practical use, the extension and retraction of the output end of the second cylinder 305 drives the thigh support arm 302 to swing in the XY direction. In conjunction with the first cylinder 304, it can effectively increase the angle and range of motion of the thigh joint, further improving the effect of joint training for patients.

[0031] In actual setup, to ensure that the thighs can swing left and right, a certain distance is maintained between the two leg training mechanisms 3 in this embodiment.

[0032] In addition, in order to facilitate the training of the patient's calf, the thigh support arm 302 in this embodiment is provided with a calf training component at the end away from the connecting arm 301, so as to connect the patient's leg to the calf component and thus realize the training of the joints of the patient's calf.

[0033] In detail, the calf training component includes a calf support arm 306 hinged to the end of the thigh support arm 302 away from the connecting arm 301 via a hinge shaft; a vertical plate 307 is installed at the bottom of the thigh support arm 302, and a third cylinder 308 is hinged to the side of the vertical plate 307 facing the calf support arm 306 via a hinge shaft. The output end of the third cylinder 308 is hinged to the calf support arm 306 via a hinge shaft to drive the calf support arm 306 to rotate on the ZX plane.

[0034] In practical application, the patient's two lower legs are connected to two lower leg support arms 306 respectively. The extension and retraction of the output end of the third cylinder 308 causes the lower leg support arms 306 to swing on the ZX plane, and at the same time causes the patient's lower legs to swing on the ZX plane. Through cooperation with the second cylinder 305, the lower leg support arms 306 can swing on the XY plane along with the thigh support arm 302 and the connecting arm 301, further improving the effect of rehabilitation training for the patient's leg joints, and effectively promoting rehabilitation training for the joints of the patient's lower legs.

[0035] It should be noted that, to ensure that the patient's thigh and lower leg can be stably connected to the thigh support arm 302 and the lower leg support arm 306 during the training process, a restraint strap 310 is provided on the outside of both the thigh support arm 302 and the lower leg support arm 306, and the patient's thigh and lower leg are connected to the thigh support arm 302 and the lower leg support arm 306 respectively through the two restraint straps 310.

[0036] In addition, to facilitate the placement of the patient's feet, a footrest 309 is rotatably connected to the end of the calf support arm 306 away from the thigh support arm 302 to provide space for the patient's feet.

[0037] In actual setup, a swing motor can be installed on the lower leg support arm 306, and the output end of the swing motor is connected to the pedal 309. The operation of the swing motor drives the pedal 309 to rotate on the ZX surface, thereby achieving the effect of rehabilitation training for the patient's ankle joint.

[0038] Although embodiments of the present invention have been shown and described, 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.
