In the clamping groove, the movement direction of the limbs is limited by the telescopic frame, and therefore the movement track of the limbs is adjusted and controlled. Meanwhile, the threaded surface on the surface of the telescopic rod and the nut work cooperatively, and the maximum contraction stroke of the telescopic rod can be limited. The limiting mechanism effectively controls the limb movement range, the patient is helped to complete the movement more conforming to the standard, and the rehabilitation training effect is practically improved.

Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training device technology, and in particular to a rehabilitation training movement correction feedback system. Background Technology

[0002] In the field of modern medicine, limb rehabilitation is a crucial step for patients with limb dysfunction caused by injury, surgery, or neurological diseases to restore physical function, improve their ability to live independently, and enhance their quality of life. Effective rehabilitation training can promote the recovery of muscle strength, improve joint range of motion, and remodel neurological function.

[0003] However, during limb rehabilitation training, patients often struggle to accurately achieve the predetermined range and angle of motion due to insufficient muscle strength, low pain tolerance, or misunderstanding of movements. Taking knee flexion and extension training as an example, if patients cannot complete the range of flexion and extension angles specified in the rehabilitation plan, it not only directly affects the training effect but may also lead to a series of adverse consequences: In the short term, substandard movements cannot effectively stimulate the target muscle groups and joint mobility; in the long term, this non-standard training pattern can lead to the solidification of incorrect movement patterns, increase compensatory load on non-target muscle groups, and even cause joint wear or secondary injury, ultimately delaying the rehabilitation process and increasing the patient's physical burden.

[0004] Therefore, there is an urgent practical need for a system that can correct the range and angle of movement during the rehabilitation process of patients' limbs, in order to improve the effectiveness of rehabilitation training and optimize the rehabilitation treatment process. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned rehabilitation training movement correction feedback system, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rehabilitation training movement correction feedback system, including a frame;

[0008] The adjustment plate is hinged to the side of the upright and can be adjusted at an angle.

[0009] The correction block is connected to the adjustment plate via multiple telescopic frames. The correction block has a guide groove and a slot. The slot is located in the center of the guide groove and is used to limit the patient's limb. The inner wall of the guide groove has a symmetrical double arc surface that tapers towards the slot to guide the patient's limb into the slot.

[0010] The telescopic frame includes:

[0011] The sliding sleeve is an integral sleeve and telescopic rod, which are elastically connected by a spring;

[0012] A threaded surface is provided on the surface of the telescopic rod, and a nut is fitted on the external thread to adjust the maximum retraction stroke of the telescopic rod.

[0013] As a preferred embodiment of the rehabilitation training movement correction feedback system of this utility model, the longitudinal section of the slot is semi-circular, and its radius of curvature matches the contour of the human limb.

[0014] As a preferred embodiment of the rehabilitation training movement correction feedback system of this utility model, the inner wall of the slot is provided with at least two symmetrically distributed protrusions.

[0015] As a preferred embodiment of the rehabilitation training movement correction feedback system of this utility model, the curvature of the circular surface of the card slot is 1.5-2 times the curvature of the arc surface of the guide slot.

[0016] In a preferred embodiment of the rehabilitation training movement correction feedback system of this utility model, the sleeve is disposed through the adjustment plate and perpendicular to the surface of the adjustment plate, and one end of the telescopic rod is connected to the correction block.

[0017] As a preferred embodiment of the rehabilitation training movement correction feedback system of this utility model, a screw is rotatably mounted on the frame, a slider is threadedly sleeved on the screw, and a connecting rod is hinged between the slider and the adjustment plate.

[0018] The beneficial effects of this invention are as follows: When the patient's limb contacts the arc surface of the guide groove on the corrective block, the limb can automatically and smoothly slide into the groove during movement, based on the structural design of the guide groove. Within the groove, the direction of limb movement is limited by the telescopic frame, thereby achieving control over the limb's movement trajectory. Simultaneously, the threaded surface of the telescopic rod works in conjunction with the nut to limit the maximum retraction stroke of the telescopic rod. This limiting mechanism effectively controls the range of limb movement, helping patients complete more standard movements and significantly improving the effectiveness of rehabilitation training.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0029] Reference Figures 1-4 As an embodiment of the present invention, a rehabilitation training movement correction feedback system is provided, which includes a stand 1, which is generally installed at the patient's bedside or on the ground.

[0030] Adjustment plate 2 is hinged to the side of stand 1. A screw 5 is rotatably mounted on stand 1. A slider 6 is threaded onto screw 5. A connecting rod 7 is hinged between slider 6 and adjustment plate 2. The user can adjust the position of slider 6 by turning screw 5, thereby causing connecting rod 7 to push adjustment plate 2 to adjust the angle, thus adjusting the angle of telescopic frame 3 to ensure that it is in the correct direction of training movement and to ensure that the patient's limb movement is correctly guided.

[0031] The correction block 4 is connected to the adjustment plate 2 via multiple telescopic frames 3. The correction block 4 has a guide groove 41 and a slot 42. The slot 42 is located in the center of the guide groove 41. The inner wall of the slot 42 has at least two symmetrically distributed protrusions 420. The protrusions 420 are made of elastic material (such as rubber or silicone) to further limit the patient's limb and reduce the amplitude of the patient's limb swaying in the slot 42, thereby making the movement more precise and the exercise effect better. The inner wall of the guide groove 41 has a symmetrical double arc surface that gradually tapers towards the slot 42 to guide the patient's limb into the slot 42. The longitudinal section of the slot 42 is semi-circular, and its radius of curvature matches the contour of the human limb. The curvature of the circular surface of the slot 42 is 1.5-2 times that of the arc surface of the guide groove 41. When the patient moves their limbs, the limbs move towards the guide groove 41. When they come into contact with the arc surface of the guide groove 41, they slide into the slot 42 along the arc surface, allowing them to move along the axis of the telescopic frame 3 (i.e., the adjusted standard movement direction), thereby correcting the direction of the patient's limb movement. In addition, the slot 42 can limit the patient's limbs, preventing the limbs from swinging too much during movement, and further standardizing their movement posture.

[0032] The telescopic frame 3 includes:

[0033] like Figure 2 and Figure 3As shown, the sliding sleeve is an integral sleeve and telescopic rod, which are elastically connected by a spring 31. The spring 31 enables the corrective block 4 to have an elastic reset function while providing a certain resistance during the patient's limb movement, thereby increasing the intensity of movement and improving the rehabilitation effect. The sleeve is installed through the adjustment plate 2 and perpendicular to the surface of the adjustment plate 2. One end of the telescopic rod is connected to the corrective block 4. The surface of the telescopic rod has a threaded surface 32, and a nut 33 is fitted on its external thread for adjusting the maximum contraction stroke of the telescopic rod. The threaded surface 32 and the nut 33 work together to limit the contraction stroke of the telescopic rod, thereby limiting the range of motion of the patient's limb, ensuring that the range of motion is within a reasonable range, and avoiding excessive strain.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
