[0058] Patients treated with the ring brace lie supine on the bed, and auxiliary fixation and exercise devices that match the specifications of the ring brace are used to improve patient comfort, safety, and rehabilitation outcomes:

[0059] The plate-shaped body 1 is placed between the annular support and the mattress of the bed. The rough lower surface of the plate-shaped body 1 can increase the static friction between it and the mattress of the bed to prevent accidental movement.

[0060] Inflate the airbag 11 until the airbag 11 completely fills the gap between the patient's knee joint and the mattress of the bed to relieve the pressure on the knee joint;

[0061] The sliding member 2 slides along the length direction of the plate-shaped body 1 on the two first sliding grooves 12 through the two first sliding blocks 21 until the position of the sliding member 2 matches the position of the annular component to be fixed;

[0062] The two second sliders 3 slide on the second sliding grooves 22 along the width direction of the plate-shaped body 1 until the two second sliders 3 are located on both sides of the annular component to be fixed;

[0063] After the annular component is placed in the fixing groove 32, the limiting bolt sequentially passes through the third limiting hole 33, the through hole opened on the annular component, and the third limiting hole 33, or the limiting bolt passes through the third limiting hole 33 and abuts against the surface of the annular component to limit the relative position of the annular component and the second slider 3; another limiting bolt sequentially passes through the second limiting hole 31 and the second limiting groove 23 to limit the relative position of the second slider 3 and the sliding member 2; and another limiting bolt sequentially passes through the first limiting hole and the first limiting groove 13 to limit the relative position of the sliding member 2 and the plate-like body 1;

[0064] After the relative positions of all the annular components are stabilized, the auxiliary fixation and exercise device can assist in fixing the annular support to ensure the comfort and safety of the patient.

[0065] Remove all the limiting bolts to release the limiting function of the annular bracket, and slide all the sliding members 2 to the nearest end or the farthest end of the plate-shaped body 1;

[0066] (If the patient does not use a ring assembly on the ankle, the patient can directly wear the device shown in prior art ZL201720800632.5 to perform active functional exercises.)

[0067] By pulling the operating portion 4242 to slide the limiting rod 424 away from the rotating shaft 422 to release the rotation limit of the rotating shaft 422, the two connecting plates 423 are rotated to match the angles of the two annular components at the patient's ankles;

[0068] After the annular assembly is placed in the connecting groove 4231, the limiting bolt is sequentially passed through the fixing hole 4232, the through hole on the annular assembly, and the fixing hole 4232, or the limiting bolt is passed through the fixing hole 4232 and then abuts against the surface of the annular assembly to limit the relative position of the annular assembly and the connecting plate 423;

[0069] By pushing the operating portion 4242 to slide the limiting rod 424 toward the rotating shaft 422, the meshing ring gear on the abutting portion 4241 of the limiting rod 424 meshes with the rotation limiting ring gear on the horizontal limiting portion 4221 of the rotating shaft 422, and the rectangular through hole 4212 restricts the rotation of the limiting rod 424, thereby restricting the rotation of the rotating shaft 422.

[0070] After all the annular components are connected to the connecting mortise 42, the auxiliary exercise wheel 4 can assist the patient receiving the annular support to perform active functional exercises on the upper smooth surface of the plate-like body 1, thereby promoting blood circulation and muscle strength recovery, and further promoting fracture healing.

[0071] It is obvious that after removing the limiting bolt and releasing the rotation limit of the rotating shaft 422, the annular bracket can be re-fixed with the assistance of the second slider 3 and the like.

[0072] In summary, the auxiliary fixation and exercise device of the present invention is intended to solve the problems existing in the use of existing annular stents, improve the patient's comfort, safety and rehabilitation effect, and has important clinical application value.

[0073] The above description is only a preferred embodiment of the present invention and does not limit the implementation method and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
