[0024] The two pressing mechanisms 1 are arranged to press the cruciate ligament, the pressing block 102 is arc-shaped on one side, the plurality of extrusion pieces 105 are arranged in an arc shape after moving, the connecting seat 107 and the fitting plate 109 are arranged in an arc shape, the plurality of fitting plates 109 are better matched with the arc of the knee after being arranged in an arc shape, the two ends of the cruciate ligament are pressed, the cruciate ligament is stabilized, the rehabilitation effect is improved, the first spring 106 and the second spring 108 are arranged, the plurality of fitting plates 109 are adapted to different knee arcs, and the plurality of fitting plates 109 are adapted to different patients.

[0025] In the above embodiment, the movement direction of the pressing block 102 is perpendicular to the knee, and the pressing operation of the fitting plate 109 is realized.

[0026] Specifically, as shown in Figure 3 , Figure 4 , Figure 6 The first box body 101 is connected with a plurality of guide rails 2, each guide rail 2 corresponds to the mounting seat 104, the mounting seat 104 slides on the guide rail 2, the sliding direction of the mounting seat 104 is perpendicular to the sliding direction of the pressing block 102, the mounting seat 104 is connected with the first motor 3, the output shaft of the first motor 3 is fixedly connected with the first gear 4, a plurality of first toothed racks 5 are connected in the first box body 101, the first toothed rack 5 is parallel to the guide rail 2, the first toothed rack 5 corresponds to the first gear 4, and the first gear 4 is engaged with the first toothed rack 5.

[0027] In the above embodiment, the first motor 3 drives the first gear 4 to rotate, the first gear 4 rotates and cooperates with the first toothed rack 5, so that the mounting seat 104 slides on the guide rail 2, the mounting seat 104 drives the extrusion piece 105, the connecting seat 107 and the fitting plate 109 to move, so as to adjust the position of the fitting plate 109, so that the fitting plate 109 can be aligned with the end of the cruciate ligament according to the knee structure of different patients.

[0028] Specifically, as shown in Figure 1 , Figure 7 , Figure 8 , Figure 9As shown, each pressing mechanism 1 is connected with a binding mechanism 6 on one side, and the two binding mechanisms 6 are fixed on the thigh and calf positions respectively. The binding mechanism 6 comprises a rotating plate 61, a second box body 62 and a second motor 63. The rotating plate 61 is rotatably connected with the first box body 101 on one side, and rotatably connected with the second box body 62 on the other side. The second motor 63 is connected in the second box body 62. The second motor 63 output shaft is fixedly connected with a rotating shaft 64. A plurality of winding drums 65 are coaxially connected on the rotating shaft 64. A pull rope 66 is wound on the winding drum 65. A plurality of clamping blocks 67 are slidably connected on both sides of the second box body 62. The clamping block 67 is hollow. The clamping block 67 corresponds to the winding drum 65 in one-to-one correspondence. A binding belt 68 is slidably connected in the clamping block 67. The binding belt 68 corresponds to the pull rope 66 in one-to-one correspondence. The binding belt 68 is fixedly connected with the pull rope 66. A plurality of second gears 69 are fixedly connected on the rotating shaft 64. A third spring 610 is fixedly connected on each clamping block 67. A second rack 611 is connected at the end of the third spring 610. Each second gear 69 corresponds to two symmetrical clamping blocks 67. The second gear 69 is meshed with the second rack 611 on both sides.

[0029] In the above embodiment, when the patient wears the auxiliary device, the second motor 63 drives the rotating shaft 64 to rotate, the rotating shaft 64 drives the plurality of winding drums 65 to rotate, so that the pull rope 66 is retracted on the winding drum 65, the pull rope 66 drives the binding belts 68 on both sides to move, the binding belts 68 slide in the hollow clamping block 67, thereby realizing the tightening operation of the binding belt 68. At the same time, the second gear 69 drives the second rack 611 on both sides to move, the second rack 611 on both sides drives the two symmetrical clamping blocks 67 to move close to each other, realizing the clamping operation of the clamping block 67. The third spring 610 plays a role, and the binding belt 68 has elasticity, so that the binding belt 68 and the clamping block 67 can clamp the thigh at the same time. When the binding belt 68 is first tightened, the binding belt 68 will be lengthened. When the clamping plate is first tightened, the third spring 610 will be lengthened.

[0030] Specifically, as shown in 1, Figure 1 , Figure 7 , Figure 8 The rotating plate 61 is provided with a sliding groove 7 on both sides. The sliding groove 7 is slidably connected with a sliding block 8. The fourth spring 9 is fixedly connected between the sliding block 8 on one side and the sliding groove 7. The two connecting rods 10 are respectively located on both sides of the rotating plate 61. Each connecting rod 10 corresponds to two sliding blocks 8 on the same side. The connecting rod 10 is hingedly connected with the two sliding blocks 8 at both ends.

[0031] In the above embodiment, when the patient walks or bends the knee, the sliding block 8 will slide in the sliding groove 7 of the rotating plate 61. The fourth spring 9 on both sides will be compressed or lengthened. The connecting rod 10 makes the two rotating plates 61 always maintain a uniform torsion angle, so that the knee will not receive the impact force of internal and external rotation.

[0032] Specifically, as shown in 1, Figure 7 ,Figure 8 , Figure 9 As shown, one of the fastening mechanisms 6 is equipped with a fine-tuning mechanism 11. The fine-tuning mechanism 11 includes an adjusting shaft 111, a knob 112, and a third gear 113. The adjusting shaft 111 is rotatably connected to the second housing 62. The knob 112 is fixed to the first end of the adjusting shaft 111. The third gear 113 is fixed to the second end of the adjusting shaft 111. A fourth gear 114 is fixedly connected to the side of the rotating plate 61 near the second housing 62. The third gear 113 meshes with the fourth gear 114. A limiting member 115 is sleeved on the outside of the fourth gear 114. The limiting member 115 is fixedly connected to the rotating plate 61. A clamping member 116 is slidably connected to the second housing 62. The clamping member 116 is used to clamp the third gear 113.

[0033] In the above embodiments, the locking member 116 can only slide and cannot rotate. Pulling the locking member 116 disengages it from the third gear 113, allowing the third gear 113 to rotate freely. Rotating the knob 112 drives the adjusting shaft 111 to rotate, which in turn drives the third gear 113 to rotate, thereby driving the rotating plate 61. The limiting member 115 ensures that the rotating plate 61 can only rotate a small angle. This adjustment is to adapt to the internal and external rotation angles of the patient's knee.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, a heating plate 12 is fixedly connected to the connecting rod 10, and a soft pad 13 is fixedly connected to one side of the bonding plate 109.

[0035] In the above embodiments, the heating plate 12 keeps the knee at a suitable temperature, and the pad 13 prevents the adhesive plate 109 from damaging the knee.

[0036] The working principle of this invention is as follows: The patient wears this auxiliary device on the knee, so that the two pressing mechanisms 1 are located on the upper and lower sides of the knee. The upper binding mechanism 6 is fixed to the thigh, and the lower binding mechanism 6 is fixed to the calf. The second motor 63 drives the rotating shaft 64 to rotate. The rotating shaft 64 drives multiple drums 65 to rotate, so that the pull rope 66 retracts on the drum 65. The pull rope 66 drives the binding straps 68 on both sides to move. The binding straps 68 slide in the hollow clamping block 67, thereby realizing the tightening operation of the binding straps 68. At the same time, the second gear 69 drives the second racks 611 on both sides to move. The second racks 611 on both sides drive the two symmetrical clamping blocks 67 to move closer to each other, realizing the clamping operation of the clamping blocks 67. The third spring 610 plays a role. At the same time, the binding straps 68 are elastic, so that the binding straps 68 and the clamping blocks 67 can clamp the thigh at the same time. When the binding straps 68 are tightened first, the binding straps 68 will be stretched. When the clamping plate is tightened first, the third spring 610 will be stretched.

[0037] After the tightening operation of the upper and lower sides is realized, the clamping part 116 can be pulled to disengage the third gear 113, at which time the third gear 113 can be freely rotated, the knob 112 is rotated, the adjusting shaft 111 is rotated, thereby driving the third gear 113 to rotate, thereby driving the rotating plate 61, and the limiting part 115 makes the rotating plate 61 only rotate a small angle, and the adjustment is to adapt to the internal and external rotation angle of the patient's knee;

[0038] Then the cruciate ligament is compressed, the electric telescopic rod 103 drives the compression block 102 to slide in the first box body 101, the arc surface of the compression block 102 acts on the end of the extrusion part 105, so that the extrusion part 105 slides on the mounting seat 104, at which time the first spring 106 is in a compressed state, the extrusion part 105 drives the connecting seat 107 and the fitting plate 109 to move through the second spring 108, so that the fitting plate 109 extrudes the cruciate ligament of the patient's knee, at which time the plurality of fitting plates 109 are arc-shaped, which can perfectly fit the curvature of the patient's knee, the first motor 3 drives the first gear 4 to move, the first gear 4 rotates and cooperates with the first rack 5, thereby making the mounting seat 104 slide on the guide rail 2, the mounting seat 104 drives the extrusion part 105, the connecting seat 107 and the fitting plate 109 to move, thereby adjusting the position of the fitting plate 109, so that the fitting plate 109 can be aligned with the end of the patient's cruciate ligament according to the knee structure of different patients, and the stable rehabilitation training operation is realized.

[0039] When the patient walks or bends the knee, the sliding block 8 will slide in the rotating plate 61 sliding groove 7, the fourth spring 9 on both sides will be compressed or lengthened, and the connecting rod 10 makes the two rotating plates 61 always maintain the same torsion angle, so that the knee will not receive the impact force of internal and external rotation.

[0040] The above only describes the preferred embodiments of the present application, and is not used to limit the protection scope of the present application.
