[0045] Reference Figure 1 The present disclosure provides a joint correction device, which is particularly suitable for human knee joints to correct varus / valgus in the joints of arthritis patients, but is not limited thereto. As needed, the joint correction device provided by the present disclosure can also be applied to human ankle joints, elbow joints, wrist joints, etc., but is not limited thereto.

[0046] The joint correction device includes a main support frame and a support pad 14. The main support frame includes an upper support 11 and a lower support 12. The upper support 11 is used to be mounted on the thigh, and the lower support 12 is used to be mounted on the calf. The bottom end of the upper support 11 is rotatably connected to the top end of the lower support 12 around the rotation axis through a connecting piece 13, so that the lower support 12 and the upper support 11 can rotate relative to each other to adapt to the extension and bending of the joint. The support pad 14 is arranged at the connection between the upper support 11 and the lower support 12. The support pad 14 can move away from or close to the main support frame along the extension direction of the rotation axis to adjust the size of the squeezing force applied to the patient's joint.

[0047] The joint correction device provided by the present invention has a support pad 14 that can move relative to the main support frame so as to be able to squeeze the joint inward or away from the joint according to the correction needs of the arthritis patient, thereby applying appropriate squeezing force to the patient's leg. This improves the versatility of the joint correction device and makes it unnecessary for the patient to customize the joint correction device separately.

[0048] Continue to refer to Figure 1 The joint correction device includes an upper bracket 11 and a lower bracket 12 which can rotate relative to each other. The upper bracket 11 is used to wrap and support the thigh, and the lower bracket 12 is used to wrap and support the calf. The upper bracket 11 extends continuously to have good supporting strength, and is arranged on the inner and outer sides of the patient's joint and is roughly symmetrically arranged to provide the patient with supporting force to avoid inversion or eversion of the joint.

[0049] In this embodiment, the upper bracket 11 extends continuously and the two ends of the upper bracket 11 are respectively located at the bottom of the upper bracket 11, and the two ends are respectively arranged at the inner and outer sides of the knee joint, but this is not limited thereto.

[0050] like Figure 3 As shown, the upper bracket 11 and the lower bracket 12 are rotatably connected to the connecting member 13 through the rotating shaft 16. Specifically, the bottom end of the upper bracket 11 is provided with an upper bracket pin hole 112, and the top end of the lower bracket 12 is provided with a lower bracket pin hole 122. The two rotating shafts 16 are rotatably provided in the upper bracket pin hole 112 and the lower bracket pin hole 122, respectively. The upper bracket 11 is rotatably connected to the connecting member 13 through the rotating shaft 16, and the lower bracket 12 is rotatably connected to the connecting member 13 through the rotating shaft 16. In this way, the upper bracket 11 and the lower bracket 12 are connected together by providing the connecting member 13. In this embodiment, the connecting member 13 is provided with a connecting member pin hole 132 for the rotating shaft 16 to pass through, and the two connecting member pin holes 132 are arranged at intervals along the longitudinal direction of the main support frame, but it is not limited thereto.

[0051] Reference Figures 1 to 3 In order to improve the stability of the joint correction device during the angle adjustment process, a first tooth portion 111 is provided at the bottom end of the upper bracket 11, and a second tooth portion 121 engaged with the first tooth portion 111 is provided at the top end of the lower bracket 12. The first tooth portion 111 and the second tooth portion 121 are engaged for transmission to prevent the lower bracket 12 from slipping relative to the upper bracket 11, thereby improving the stability and reliability of the joint correction device.

[0052] Continue to refer to Figure 3 and Figure 4 The joint correction device also includes a screw 15, and the support pad 14 is connected to the connecting member 13 through the screw 15. The screw 15 is rotatably connected to one of the support pad 14 and the connecting member 13, and the other is provided with a connecting portion matching the screw 15, and the screw 15 is connected to the connecting portion. The screw 15 is arranged roughly parallel to the rotating shaft 16. When the screw 15 is rotated, the distance between the support pad 14 and the connecting member 13 along the extension direction of the rotation axis increases or decreases. The present disclosure sets the support pad 14 to be able to move away from or close to the connecting member 13 by setting the screw 15, which has a simple structure and is easy to adjust. Continue to refer to Figure 3 and Figure 4 In this embodiment, the spiral member 15 is rotatably connected to the support pad 14, and the connecting portion is disposed on the connecting member 13 as an example for description, but the present invention is not limited thereto.

[0053] Specifically, the spiral member 15 is provided with an external thread, and the connecting part is a connector adjustment hole 131 provided on the connector 13. The spiral member 15 includes a screw rod 153, and the screw rod 153 is spirally inserted into the connector adjustment hole 131. The external thread of the screw rod 153 is threadedly matched with the connector adjustment hole 131. When the spiral member 15 is rotated, the spiral member 15 spirally rotates relative to the connector 13, and drives the support pad 14 to move closer to or away from the connector 13, thereby realizing the distance adjustment between the connector 13 and the support pad 14, and also adjusting the distance between the support pad 14 and the main support frame, so as to adjust the squeezing force on the patient's joints and adapt to different degrees of inversion or eversion of different patients.

[0054] Furthermore, the end of the spiral member 15 located on the inner side of the main support frame (referred to as the inner end) can be rotatably engaged with the support pad 14. For example but not limited to, the spiral member 15 also includes a locking portion 151 located at the inner end of the screw rod 153.

With such arrangement, the spiral member 15 can rotate relative to the support pad 14 around the axis of the screw rod 153 , but cannot move axially relative to the support pad 14 and detach from the support pad 14 , so that the spiral member 15 is rotatably clamped on the support pad 14 .

[0055] In this embodiment, the engaging portion 151 is cylindrical, and the axis of the engaging portion 151 is parallel to or coincides with the axis of the screw rod 153, but the present invention is not limited thereto. The engaging portion 151 may also be spherical, hemispherical, ellipsoidal, etc.

[0056] Continue to refer to Figure 4 In order to facilitate adjustment, a non-circular countersunk hole 152 is provided at the end (referred to as the outer end) of the spiral 15 disposed outside the main support frame. For example, but not limited to, a hexagonal countersunk hole 152 is provided at the outer end of the spiral 15. The joint correction device also includes an adjustment wrench 20. The adjustment wrench 20 is provided with a hexagonal prism matching the hexagonal countersunk hole 152. The spiral 15 can be driven to rotate by screwing the adjustment wrench 20, and the support pad 14 can be driven to move closer to or away from the main support frame. Optionally, the above-mentioned countersunk hole 152 can be triangular, rectangular, or can be set to be five-shaped. There are no excessive restrictions here, as long as the adjustment wrench 20 can drive the spiral 15 to rotate.

[0057] return Figure 3 In this embodiment, the screw 15 and the connector 13 are threadedly matched, and the support pad 14 is driven to move closer to or away from the connector 13 by rotating the screw 15. Furthermore, each support pad 14 is provided with two screws 15, and the two screws 15 are respectively provided on both sides of the width direction of the main support frame, but not limited to this. As an example, the connector 13 is provided with two connector adjustment holes 131, and the two connector adjustment holes 131 are respectively provided on both sides of the width direction of the main support frame, so as to prevent the screw 15 from affecting the relative rotation between the upper bracket 11 and the lower bracket 12, thereby improving the reliability of the joint correction device.

[0058] In this embodiment, the connector 13 can be arranged on the outside of the support pad 14 and on the inside of the main support frame, but it is not limited thereto, and the connector 13 can also be arranged on the outside of the main support frame. The inside defined in this disclosure is the side of the main support frame facing the patient's affected part, and the outside is the side of the main support frame facing away from the patient's affected part.

[0059] Continue to refer to Figures 2 to 4 In this embodiment, in order to further improve the reliability of the joint correction device, two connecting parts 13 are provided at each connection, and the two connecting parts 13 are symmetrically arranged on both sides of the main support frame along the extension direction of the rotation axis. The two connecting parts 13 are respectively connected to the main support frame through the rotating shaft 16, so that the two connecting parts 13, the upper bracket 11 and the lower bracket 12 are connected together through the rotating shaft 16, so that the two connecting parts 13, the upper bracket 11 and the lower bracket 12 do not axially move and separate from each other in the extension direction of the rotating shaft 16, thereby improving the reliability of the joint correction device.

[0060] Optionally, the two connecting members 13 have the same structure. In this embodiment, the two connecting members 13 are threadedly matched with the spiral member 15 to improve the connection strength of the support pad 14, but this is not limited to the connecting member 13 located between the support pad 14 and the main support frame, that is, the connecting member adjustment hole 131 of the connecting member 13 arranged close to the support pad 14 can also be a light hole.
