Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training instruments, and in particular to a wrist joint rehabilitation device. Background Art

[0002] With the development of modern science and technology, more and more people pay attention to rehabilitation after injury. At present, most rehabilitation equipment on the market are large in size and weight, and inconvenient to transport. The rehabilitation rooms of current rehabilitation departments need to accommodate many equipment, and many of them have requirements for small size and small weight.

[0003] Currently, wrist joint rehabilitation devices on the market are large in size and heavy in mass, and most of them only have one active or passive function. The structure is too simple and the function is too single, and they can only move in a single dimension. If you need to move in different dimensions, you need to use different wrist joint rehabilitation devices, which is inconvenient and requires more space.

[0004] Prior art 1: A Chinese utility model patent with application number 202121119666.0, entitled "A wrist joint rehabilitation trainer", comprises a base plate, an arm fixing structure is provided on the base plate, and an exercise device corresponding to the arm fixing structure is rotatably connected to the base plate; the exercise device comprises a rotating disk rotatably connected to the base plate, and a locking structure cooperating with the rotating disk is provided on the base plate; a slider is slidably connected in the exercise cavity, and a resistance structure cooperating with the slider is provided in the exercise cavity; a driving structure cooperating with the slider is provided on the exercise cavity, and an adjustment structure cooperating with the driving structure is also provided in the exercise cavity.

[0005] Prior art 2: The Chinese invention patent with application number 202410308549.0 and titled "A bionic wrist joint rehabilitation training device with adjustable end" is symmetrical about the sagittal plane, including a base support assembly fixedly connected to the base, a first motor assembly fixedly connected to the upper surface of the rear end of the base, an outer ring of a turntable bearing arranged in the turntable assembly fixedly connected to the upper surface of the front end of the base, a second motor assembly connected to the turntable assembly, and a palm fixing assembly fixedly connected to the top of the column of the turntable with a column in the turntable assembly; the base support assembly includes a first hexagon socket bolt that passes through the first beam and the first spring in sequence and is screwed into the second support frame; the palm fixing assembly includes a second spring, a second beam, and a third hexagon socket bolt that are embedded in the front end of the longitudinal beam in sequence; when the patient holds the second beam with his hand, the first hexagon socket bolt and the third hexagon socket bolt are twisted to adjust the height of the first beam and the longitudinal depth of the second beam, thereby ensuring that the patient's wrist joint motion axis is consistent with the center axis of the type IV linear optical axis with keyway milling groove.

[0006] Prior art three: A Chinese invention patent with application number 202111410012.8 and name “A Wrist Joint Rehabilitation Device”, which includes an adjustable OT table, a fixed base plate is arranged on the adjustable OT table, and a rehabilitation mechanism and a multi-directional adjustable arm rest are respectively arranged on both sides of the fixed base plate.

[0007] The rehabilitation mechanism comprises a frame, a servo motor arranged in the frame, a bearing support and a cover shell arranged above the frame, and a connecting shaft rotatably arranged on the bearing support, and the connecting shaft is driven by the servo motor.

[0008] The frame is also provided with an angle encoder for detecting the rotation angle of the connecting shaft; the bearing supports on both sides of the connecting shaft are provided with buffer columns for limiting the rotation of the connecting shaft; the cover is arranged above the frame, and emergency stop switches are respectively provided on both sides of the cover to stop the operation of the servo motor.

[0009] One end of the connecting shaft extends out of the cover shell and is coaxially connected to a transition shaft, and one end of the transition shaft is detachably connected to a rehabilitation handle, which is one of an ulna handle, a pronation and supination handle, or a flexion and extension handle.

[0010] The multi-directional adjustable arm support comprises a fixing seat, a length telescopic rod rotatably arranged on the fixing seat, a height telescopic rod vertically arranged on the length telescopic rod, and a wrist support arranged on the height telescopic rod.

[0011] However, the rehabilitation devices in the prior art all have certain defects, namely:

[0012] The disadvantage of the product of the prior art 1 is that the passive wrist training is achieved by springs and sliders, the wrist force direction is single, the dimension is single, the wrist muscles cannot be trained comprehensively, and it is not conducive to the recovery of the wrist.

[0013] The disadvantages of the product of the second prior art are that it is large in size and weight, not easy to carry, high in cost, and has a complex structure and is easy to damage.

[0014] The disadvantages of the product of the prior art three are that the exercise mode is single, passive training is not supported, and the wrist cannot be trained in an all-round way.
