Description

Technical Field

[0001] The utility model relates to a knee joint rehabilitation orthosis device. Background Art

[0002] The recovery process after knee injury or surgery usually requires the use of orthotics to support and protect the knee joint and promote recovery. Traditional orthotics are often fixed or have limited adjustments to accommodate different patients' leg sizes and the needs of the recovery stage.

[0003] However, these traditional devices have some shortcomings. The adjustment mechanism of traditional devices is mostly a preset fixed position, which is difficult to fine-tune according to the patient's specific leg structure and rehabilitation progress, which may lead to poor orthopedic effect or discomfort. In addition, during the adjustment process, it is difficult for the user to obtain intuitive feedback to confirm whether the device has been adjusted to the appropriate position. This may require repeated trial and error, which increases the adjustment time. In view of this, the utility model proposes a knee joint rehabilitation orthosis device to solve the above problems.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] like Figure 1-8 As shown, this embodiment proposes a knee joint rehabilitation orthosis device, comprising two groups of limit frames 10, two groups of connecting plates 30 are arranged between the two groups of limit frames 10, and movable plates 50 are arranged on the connecting plates 30, and correction pads 20 are arranged on the movable plates 50;

[0032] A positioning plate 40 is provided on the connecting plate 30, the limiting frame 10 is provided between the positioning plate 40 and the connecting plate 30, a positioning rod 41 is provided between the positioning plate 40 and the connecting plate 30, a penetrating positioning hole 44 is provided at the positioning rod 41, an adjusting screw 52 is provided on the movable plate 50, the adjusting screw 52 is slidably provided in the positioning hole 44, an adjusting block 90 is also provided on the positioning plate 40, the adjusting block 90 is sleeved on the outer wall of the adjusting screw 52, ​​the adjusting block 90 cooperates with the adjusting screw 52, ​​the adjusting block 90 rotates, and drives the movable plate 50 to move axially along the adjusting screw 52.

[0033] In this case, the correction pad 20 is a prior art and will not be described in detail here.

[0034] In this embodiment, when the relative position of the correction pad 20 needs to be adjusted, the adjustment round block 90 is manually driven to rotate, and the adjustment screw 52 can be displaced along the axial direction of the adjustment screw 52 by the threaded cooperation between the adjustment round block 90 and the adjustment screw 52, ​​thereby driving the movable plate 50 to displace and adjust the relative position of the correction pad 20 until the correction pad 20 can smoothly contact the leg;

[0035] By rotating the adjustment knob 90, the adjustment screw 52 can be displaced along its axial direction, thereby achieving precise displacement of the movable plate 50, and then adjusting the relative position of the correction pad 20. The rotation structure of the present technical solution simplifies the adjustment process of the orthotic device, allowing the operator to quickly and accurately adjust the correction pad 20 to the appropriate position according to the actual situation of the patient's legs, so as to achieve the best rehabilitation support and orthotic effect. In addition, due to the reasonable design of the adjustment mechanism, it can be conveniently adjusted by manually rotating the adjustment knob 90 without the need for additional tools, which increases the convenience of use, reduces the difficulty of operation, and is conducive to improving the reliability and durability of the rehabilitation orthotic device.

[0041] Of course, the observation slot 91 on the adjustment block 90 can provide the user with an intuitive indication means to observe and monitor the rotation progress of the adjustment block 90 and the displacement of the adjustment screw 52. The setting of the observation slot 91 allows the user to accurately judge the rotation angle of the adjustment block 90, and thereby deduce the specific displacement of the movable plate 50 along the axial direction of the adjustment screw 52, ​​thereby achieving precise control of the position adjustment of the correction pad 20. Such a design simplifies the operation process and improves the accuracy and repeatability of the adjustment of the orthotic device, so that the user can effectively fine-tune the correction pad 20 according to the recovery of the leg. In addition, through the visual feedback provided by the observation slot 91, the user can quickly understand the axial displacement of the adjustment screw 52 when the adjustment block 90 rotates one circle, so as to make the necessary adjustments more efficiently and accurately. This design optimizes the user's operating experience and helps to improve the efficiency of the use of rehabilitation orthotic devices.

[0044] In this embodiment, the fixed rod 70 is provided to support the limiting frame 10, so that the limiting frame 10 can be rotated and adjusted about the axis of the fixed rod 70, so that the limiting frame 10 can adapt to the bending state of the patient's legs.

[0045] Specifically, a placement groove 42 is provided on the positioning plate 40 , a placement hole 421 is provided in the placement groove 42 , the placement hole 421 matches the position of the fixing hole 31 , a placement bolt 60 is arranged in the placement hole 421 , and the placement bolt 60 is threadedly connected to the fixing rod 70 .

[0046] In this embodiment, by the cooperation between the placement bolts 60 and the fixing rods 70 , when the limiting frame 10 needs to be disassembled, the limiting frame 10 can be detached from the connecting plate 30 by disassembling the fixing rods 70 .

[0047] Specifically, the placement bolt 60 and the fixing rod 70 are provided with a penetrating sliding hole 80, and the movable plate 50 is provided with a sliding rod 51;

[0048] The sliding rod 51 is slidably disposed in the sliding hole 80 .
