[0002] Patients with ligament injuries, such as those with posterior cruciate ligament injuries and anterior cruciate ligament injuries, generally use ordinary rehabilitation braces, bandages, and other health care equipment for simple fixation during the rehabilitation period. However, this can cause secondary damage during daily activities, such as excessive knee flexion or range of motion, leading to serious problems where the ligaments cannot return to normal even after rehabilitation.

Detailed Implementation

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] See Figure 1 , Figure 1 This diagram illustrates the structure of a rehabilitation brace according to an embodiment of the present invention. The rehabilitation brace includes a movable component 10, a first fixing part 20, and a second fixing part 40. The first fixing part 20 is used to fit onto the lower leg 60 (e.g., ...). Figure 11 As shown), the second fixing part 40 is used to be sleeved on the thigh 70 (as shown). Figure 11 (As shown above).

[0044] See Figures 2 to 5 , Figure 2 It shows Figure 1 Enlarged structural diagram at point A Figure 3 It shows Figure 1 Another structural view of the rehabilitation brace shown. Figure 4 It shows Figure 1 The diagram shown is an exploded view of the movable component 10 of the rehabilitation brace. Figure 5 It shows Figure 4 An enlarged structural diagram at point B. Specifically, the movable component 10 includes a first rotating plate 11, a second rotating plate 12, a first connecting member 13, a second connecting member 14, a third connecting member 15, and a fourth connecting member 16. The first connecting member 13 and the second connecting member 14 are rotatably connected to one side of the first fixed part 20 and the second fixed part 40 via the first rotating plate 11; the third connecting member 15 and the fourth connecting member 16 are rotatably connected to the other side of the first fixed part 20 and the second fixed part 40 via the second rotating plate 12. The line connecting the rotation center of the first connecting member 13 and the rotation center of the second connecting member 14 is o, and the line connecting the rotation center of the third connecting member 15 and the rotation center of the fourth connecting member 16 is p. The lines o and p intersect.

[0045] Specifically, one end of the first rotating plate 11 is rotatably connected to one side of the frame of the first fixing part 20 (for example, the side of the first frame 21 facing away from the lower leg 60) via the first connector 13, and the other end of the first rotating plate 11 is rotatably connected to one side of the frame of the second fixing part 40 (for example, the side of the second frame 41 facing away from the thigh 70) via the second connector 14. One end of the second rotating plate 12 is rotatably connected to the other side of the frame of the first fixing part 20 (for example, the side of the first frame 21 that fits against the lower leg 60) via the third connector 15, and the other end of the second rotating plate 12 is rotatably connected to the other side of the frame of the second fixing part 40 (for example, the side of the second frame 41 that fits against the thigh 70) via the fourth connector 16.

[0046] When the aforementioned movable component 10 is assembled with the first fixing part 20 and the second fixing part 40, the first fixing part 20 is fitted onto the lower leg 60, and the second fixing part 40 is fitted onto the thigh 70. The movable component 10 is located on one side of the knee. During walking, because one end of the first rotating plate 11 and one end of the second rotating plate 12 are rotatably connected to the two opposite sides of the first fixing part 20, and the other end of the first rotating plate 11 and the other end of the second rotating plate 12 are rotatably connected to the two opposite sides of the second fixing part 40, both the first fixing part 20 and the second fixing part 40 can only rotate relative to the movable component 10, thus enabling knee flexion. At the same time, the movable component 10 provides support, preventing secondary injury caused by the first fixing part 20 or the second fixing part 40 shifting to the side when the force is unbalanced. Furthermore, the line connecting the rotation center of the first connector 13 and the rotation center of the second connector 14 is o, and the line connecting the rotation center of the third connector 15 and the rotation center of the fourth connector 16 is p. The line o and the line p are intersected, so the support effect of the movable component 10 is similar to that of the knee, which provides good support for the thigh 70 and lower leg 60 of ligament patients. At the same time, the use of the rehabilitation brace is more flexible.

[0047] Please see Figure 2 , Figures 5 to 7In one embodiment, the movable component 10 further includes a limiting member 17. The limiting member 17 is disposed on the first rotating plate 11 or the second rotating plate 12, and is used to abut against the first connecting member 13, the second connecting member 14, the third connecting member 15, the fourth connecting member 16, the frame edge of the first fixing part 20 or the frame edge of the second fixing part 40 when the frame edge of the first fixing part 20 rotates relative to the frame edge of the second fixing part 40 to a preset angle. Thus, when the lower leg 60 moves relative to the first fixing part 20 on it and the second fixing part 40 on the thigh 70, when the first fixing part 20 and the second fixing part 40 move to their limit angle, the limiting member 17 abuts against the first connecting member 13, the second connecting member 14, the third connecting member 15, the fourth connecting member 16, the frame edge of the first fixing part 20 or the frame edge of the second fixing part 40 to limit the movement. This prevents the first fixing part 20 and the second fixing part 40 from continuing to rotate relative to each other when they are in the abutting state, which is equivalent to limiting the range of motion of the thigh 70 and the lower leg 60, which is beneficial to the rehabilitation effect.

[0048] It should be noted that the first rotating plate 11 can be arranged on the side of the first fixing part 20 and the second fixing part 40 away from the lower leg 60, or it can be arranged on the side of the first fixing part 20 and the second fixing part 40 close to the lower leg 60; this is not limited here. To make the technical solution of the present invention clearer, in this embodiment, as... Figure 1 , Figures 5 to 7 As shown, the following is a detailed description using the example of the first rotating plate 11 located on the side of the first fixing part 20 and the second fixing part 40 away from the lower leg 60, and the second rotating plate 12 located on the side of the first fixing part 20 and the second fixing part 40 close to the lower leg 60.

[0049] In addition, please see Figure 2 , Figures 5 to 7 In one embodiment, the limiting member 17 is adjustablely disposed on the first rotating plate 11. The limiting member 17 is used to abut against the fourth connecting member 16 when the frame edge of the first fixing part 20 rotates relative to the frame edge of the second fixing part 40 to a preset angle. Thus, by adjusting the position of the limiting member 17 on the first rotating plate 11, the limit angle of rotation of the first fixing part 20 relative to the second fixing part 40 can be adjusted accordingly. Since this limit angle is determined based on the position of the limiting member 17, the placement position of the limiting member 17 on the first rotating plate 11 can be determined based on the limit angle.

[0050] Please see Figure 2 , Figure 5 and Figure 6In one embodiment, there are two limiting members 17, located on opposite sides of the fourth connecting member 16. Thus, when the first frame and the second frame rotate relative to each other, the fourth connecting member 16 can abut against and be fixed to the upper limiting member 17 to prevent further relative rotation between the first and second frames, or abut against and be fixed to the lower limiting member 17 to prevent further relative rotation between the first and second frames, thereby achieving an angle q between the first and second frames (e.g., ...). Figure 9 (As shown) is within a preset angle range, such as 90° to 180°, 120° to 150°, or 105° to 150°, etc., which is set according to the actual situation of the ligament patient.

[0051] Please see Figure 2 , Figure 5 and Figure 6 In one embodiment, the first rotating plate 11 has an arc-shaped notch 111, which is arranged along the moving path of the fourth connector 16 and exposes the fourth connector 16. The limiting member 17 has a stop 171, which passes through the notch 111 and abuts against the fourth connector 16.

[0052] It should be noted that the moving path refers to the section of the path that the fourth connecting member 16 moves on the first rotating plate 11 during the mutual rotation of the first fixed part 20 and the second fixed part 40.

[0053] Please see Figure 2 , Figure 5 and Figure 6 In one embodiment, a step 112 is provided on the opening wall of the notch 111, and the limiting member 17 is adjustablely disposed on the step 112. Thus, with the limiting member 17 disposed on the step 112, it can be located within the notch 111, and does not need to be directly disposed on the surface of the first rotating plate 11 and protrude beyond the surface of the first rotating plate 11, thereby improving product performance. As an optional solution, the limiting member 17 can also be directly connected to the surface of the first rotating plate 11, thus eliminating the need for the step 112 described in the above embodiment on the opening wall of the notch 111; this is not a limitation here.

[0054] Please see Figure 2 , Figure 5 and Figure 6In one embodiment, the first rotating plate 11 has an arc-shaped mounting hole 113. The arc-shaped setting direction of the mounting hole 113 corresponds to the arc-shaped setting direction of the notch 111. The limiting member 17 is mounted on the first rotating plate 11 through the mounting hole 113 by a fastener 172. The fastener 172 is adjustablely positioned in the mounting hole 113 along the arc-shaped setting direction of the mounting hole 113. Specifically, the fastener 172 is, for example, a bolt, screw, screw, or other part that can be detachably fastened in the mounting hole 113. When it is necessary to adjust the mounting position of the limiting member 17 on the first rotating plate 11, the fastener 172 is loosened, and the position of the fastener 172 in the mounting hole 113 can be infinitely adjusted along the arc-shaped setting direction of the mounting hole 113. After the position of the fastener 172 in the mounting hole 113 is adjusted to the correct position, the fastener 172 is fastened in the mounting hole 113. Furthermore, since the arcuate direction of the mounting hole 113 corresponds to the arcuate direction of the notch 111, during the adjustment of the fastener 172 along the mounting hole 113, the stop 171 of the limiting member 17 is always adjusted along the notch 111, thus ensuring that the stop 171 of the limiting member 17 is always within the notch 111. Additionally, the mounting hole 113 may be specifically located, for example, on the step 112.

[0055] Please see Figure 2 , Figure 5 and Figure 6 In one embodiment, multiple angle marks are provided on the surface of the first rotating plate 11, and all angle marks are arranged sequentially along the notch 111. Thus, the angular position of the limiting member 17 on the notch 111 can be observed and determined through the angle marks, thereby allowing the determination of the rotation angle range of the first fixing part 20 and the second fixing part 40. Furthermore, the mounting position of the limiting member 17 on the first rotating plate 11 can be adjusted according to the angle marks, thereby adjusting the rotation angle range of the first fixing part 20 and the second fixing part 40 accordingly. Specifically, the angle marks are, for example, scale lines, numbers, letters, etc., provided on the surface of the first rotating plate 11.

[0056] Please see Figures 7 to 8 , Figure 7 and Figure 8 It is shown that when the fourth connector 16 abuts against the upper limiting member 17, the included angle q between the first fixing part 20 and the second fixing part 40 is 180°. Under the abutment and limiting action of the limiting member 17, the fourth connector 16 can only move along the notch 111 and in the area between the two limiting members 17. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 180°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q less than 180°.

[0057] Please see Figures 9 to 10 , Figure 9 and Figure 10 It is shown that when the fourth connector 16 abuts against the upper limiting member 17, the included angle q between the first fixing part 20 and the second fixing part 40 is 165°. Under the abutment and limiting action of the limiting member 17, the fourth connector 16 can only move along the notch 111 and in the area between the two limiting members 17. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 165°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q less than 165°.

[0058] Please see Figures 11 to 12 , Figure 11 and Figure 12 It is shown that when the fourth connector 16 abuts against the upper limiting member 17, the included angle q between the first fixing part 20 and the second fixing part 40 is 135°. Under the abutment and limiting action of the limiting member 17, the fourth connector 16 can only move along the notch 111 and in the area between the two limiting members 17. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 135°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q less than 135°.

[0059] Please see Figures 13 to 14 , Figure 13 and Figure 14 It is shown that when the fourth connector 16 abuts against the lower limiting member 17, the included angle q between the first fixing part 20 and the second fixing part 40 is 105°. Under the abutment and limiting action of the limiting member 17, the fourth connector 16 can only move along the notch 111 and in the area between the two limiting members 17. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q less than 105°, and the first fixing part 20 and the second fixing part 40 can rotate to make the included angle q greater than 105°. Furthermore, when the fourth connecting member 16 abuts against the upper limiting member 17, the included angle q between the first fixing part 20 and the second fixing part 40 is 135°. Under the limiting action of the limiting member 17, the fourth connecting member 16 can only move along the notch 111 and within the area between the two limiting members 17. That is, the first fixing part 20 and the second fixing part 40 cannot rotate to make the included angle q greater than 135°, and when the first fixing part 20 and the second fixing part 40 rotate, the included angle q is less than 135°. Therefore, Figure 13 and Figure 14 When the first fixing part 20 and the second fixing part 40 shown rotate relative to each other, the included angle q ranges from 105° to 135°.

[0060] In one embodiment, the rehabilitation brace further includes a locking assembly 50 and a pad 30. The bracket 51 is disposed on the first fixing part 20, and the end of the locking assembly 52 is connected to the pad 30.

[0061] Please see Figures 15 to 18 , Figure 15 It shows Figure 1 The diagram shows the structure of the locking assembly 50 of the rehabilitation brace. Figure 16 It shows Figure 15 Enlarged structural diagram at point G Figure 17 It shows Figure 15 The diagram shows a cross-sectional view of the locking assembly 50. Figure 18 It shows Figure 17 An enlarged structural diagram at point H. Specifically, the locking assembly 50 includes a bracket 51, a locking element 52, an unlocking element 53, and a driving element 54. The bracket 51 is mounted on the first fixing part 20 of the rehabilitation brace. The locking element 52 is a rigid, elongated strip-shaped component, movably mounted on the bracket 51. The locking element 52 has multiple locking portions 521 extending along its length. One end of the locking element 52 is a free end, and the other end is connected to the pad 30 of the rehabilitation brace. The unlocking element 53 is mounted on the bracket 51 and can lock and release the locking portions 521. The driving member 54 is rotatably mounted on the bracket 51. The driving member 54 has a first force-applying part 5411 and a second force-applying part 5431. The first force-applying part 5411 can abut against the locking part 521 to drive the locking part 52 to move relative to the bracket 51 along its length direction. The distance between the first force-applying part 5411 and the rotation axis of the driving member 54 on the bracket 51 is a first distance, and the distance between the second force-applying part 5431 and the rotation axis of the driving member 54 on the bracket 51 is a second distance. Specifically, the first distance is smaller than the second distance.

[0062] It should be noted that the length direction of the locking member 52 refers to the direction from one end of the locking member 52 to the other end of the locking member 52, such as... Figure 15 As shown by arrow S in the diagram.

[0063] When the locking assembly 50 adjusts the tightness of the pad 30 against the back of the calf 60, the unlocking member 53 releases the locking part 521, and simultaneously acts on the second force application part 5431 to drive the driving member 54 to rotate. When the driving member 54 rotates, it abuts against the locking part 521 of the locking member 52 through the first force application part 5411 and drives the locking member 52 to move relative to the bracket 51 along its length. During the movement of the locking member 52, the pad 30 moves, so that the pad 30 is pressed against the back of the calf 60. When the position of the pad 30 is adjusted to the correct position, the unlocking member 53 locks the locking part 521. When it is necessary to loosen the pad 30 from the back of the calf 60, the unlocking member 53 releases the locking part 521 and the locking member 52 is removed. Because the second distance is greater than the first distance, based on the lever principle, when the second force-applying part 5431 is pushed by hand, the forward pushing force of the first force-applying part 5411 on the locking part 52 is greater than the pushing force applied to the second force-applying part 5431. This ensures that the pad 30 securely fixes the lower leg 60, preventing it from easily loosening and avoiding displacement during activity. Adjustment is also relatively convenient and quick. Furthermore, the pad 30 fits snugly against the back of the lower leg 60 of patients with ligament injuries, ensuring proper support for the back of the lower leg 60 and guaranteeing a better rehabilitation effect.

[0064] Please see Figures 15 to 18 In one embodiment, the locking part 521 is a limiting groove provided on one side of the locking member 52. The unlocking member 53 can move into the limiting groove to lock the locking member 52, or can move outward from the limiting groove to release the locking member 52. Thus, when it is necessary to lock the locking member 52, the unlocking member 53 is moved into the limiting groove, and the unlocking member 53 abuts against the inner wall of the limiting groove to lock the locking member 52; when it is necessary to release the locking member 52, the unlocking member 53 is moved outward from the limiting groove, and the unlocking member 53 releases the locking member 52. At this time, the locking member 52 can be pushed to move freely along the length direction relative to the bracket 51 to adjust the tightness of the pad 30 on the lower leg 60.

[0065] Please see Figure 1 , Figure 16 and Figure 18, in one embodiment, the limiting groove is a one-way groove. Specifically, the limiting groove is provided with a first inner wall 5211 and a second inner wall 5212 arranged in sequence along the length direction of the locking member 52. Both the first inner wall 5211 and the second inner wall 5212 are arranged at an angle with the other side surface of the locking member 52. The angle between the first inner wall 5211 and the other side surface of the locking member 52 is a, and the angle between the second inner wall 5212 and the other side surface of the locking member 52 is b, and a < b. Thus, the limiting groove is a one-way groove, that is, the locking member 52 can move unidirectionally on the bracket 51, and the opposite moving direction will be restricted by the unlocking member 53 and cannot move. In addition, when it is necessary to make the cushion 30 close to the calf 60, there is no need to manually adjust the unlocking member 53 to loosen the locking member 52. Since the limiting groove is a one-way groove, the driving member 54 can be directly acted on. When the driving member 54 receives a driving force, it drives the locking member 52 to move along its length direction, and the position of the locking member 52 can be correspondingly adjusted to make the cushion 30 close to the calf 60.

[0066] In one embodiment, a is 20° to 70°, specifically, for example, 20°, 30°, 35°, 45°, 50°, 60° and 70°, etc. In addition, b is 60° to 100°, specifically, for example, 60°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, etc.

[0067] As an alternative solution, the limiting groove is not limited to being set as the above-mentioned one-way groove, and it can be set as a groove with a two-way limiting function, that is, whether it is necessary to make the locking member 52 drive the cushion 30 to close to the calf 60 or it is necessary to make the locking member 52 drive the cushion 30 to loosen from the calf 60, it is necessary to first move the unlocking member 53 out of the limiting groove, that is, first loosen the locking member 52 and then adjust the position of the locking member 52.

[0068] As an alternative solution, the locking part 521 is not limited to the limiting groove in the above embodiment, and it can also be, for example, a convex block that is in limiting cooperation with the unlocking member 53.

[0069] Please refer to Figure 1 , Figure 16 and Figure 18, in one embodiment, the unlocking member 53 is rotatably disposed on the bracket 51. The unlocking member 53 is provided with a locking portion 531. When the unlocking member 53 rotates, the locking portion 531 can move into the limiting groove to lock the locking member 52, or can move outwards from the limiting groove to release the locking member 52. Thus, since the limiting groove is a one-way groove, the unlocking member 53 can rotate to make the locking portion 531 move into the limiting groove. After the locking portion 531 moves into the limiting groove, the locking portion 531 abuts against the second inner wall 5212 of the limiting groove to lock and fix the locking member 52, so that the locking member 52 can only move unidirectionally on the bracket 51; in addition, the unlocking member 53 can also rotate to make the locking portion 531 move out of the limiting groove, and after the locking portion 531 moves out of the limiting groove, the unlocking member 53 releases the locking member 52.

[0070] Please refer to Figure 1 、 Figure 16 and Figure 18 , specifically, the unlocking member 53 is provided with a first shaft hole 532, and the bracket 51 is provided with a second shaft hole 511. The unlocking member 53 is rotatably disposed on the bracket 51 through a first rotating shaft (not shown in the figure) passing through the first shaft hole 532 and the second shaft hole 511.

[0071] Please refer to Figure 1 、 Figure 16 and Figure 18 , in one embodiment, the locking portion 531 is provided with two abutting surfaces 5311 disposed at an angle. The included angle between the two abutting surfaces 5311 is r. The two abutting surfaces 5311 are respectively used to abut against the first inner wall 5211 and the second inner wall 5212 of the limiting groove. The first inner wall 5211 and the second inner wall 5212 are disposed at an angle, and the included angle between the first inner wall 5211 and the second inner wall 5212 is t, and r < t. Thus, since r < t, that is, when the locking portion 531 rotates with the unlocking member 53, it can smoothly rotate and move into the limiting groove, and after the locking portion 531 rotates with the unlocking member 53 and moves into the inside of the limiting groove, the locking portion 531 has a good unidirectional fixing effect on the locking member 52.

[0072] Of course, as an optional solution, the two abutting surfaces 5311 of the locking portion 531 do not need to be disposed at an angle as in the above embodiment, and can also be, for example, parallel to each other, and can also play a unidirectional fixing role on the locking member 52 after rotating and moving into the inside of the limiting groove.

[0073] Please refer to Figure 1 、 Figure 16 and Figure 18In one embodiment, the locking assembly 50 further includes a first reset member 55. The unlocking member 53 is connected to the bracket 51 via the first reset member 55. The first reset member 55 drives the unlocking member 53 to rotate, so that the locking part 531 moves into the limiting groove. Thus, under the reset force of the first reset member 55, the locking part 531 of the unlocking member 53 is always kept in the limiting groove, thereby always providing a unidirectional limiting and fixing effect on the locking member 52; only under the action of an external driving force can the unlocking member 53 overcome the reset force of the first reset member 55 and move the locking part 531 out of the limiting groove to unlock.

[0074] In one embodiment, the first reset element 55 is a torsion spring or an elastic block.

[0075] Please see Figure 1 , Figure 16 and Figure 18 In one embodiment, the driving member 54 includes a first driving plate 541, a rotating part 542, and a second driving plate 543. The first driving plate 541 and the second driving plate 543 are respectively connected to the rotating part 542. The rotating part 542 is rotatably mounted on the bracket 51, a first force-applying part 5411 is mounted on the first driving plate 541, and a second force-applying part 5431 is mounted on the second driving plate 543.

[0076] Please see Figure 1 , Figure 16 and Figure 18 Specifically, the rotating part 542 is provided with a third shaft hole 5421, and the bracket 51 is provided with a fourth shaft hole 512. The rotating part 542 is rotatably mounted on the bracket 51 through the third shaft hole 5421 and the fourth shaft hole 512 via a second rotating shaft (not shown in the figure).

[0077] Please see Figure 1 , Figure 16 and Figure 18 In one embodiment, the second drive plate 543 is provided with a clearance opening 5432 that exposes the unlocking member 53. In this way, the unlocking member 53 is exposed outside the bracket 51 through the clearance opening 5432, and can be directly acted upon, so that the locking part 531 of the unlocking member 53 moves out of the limiting groove, and the movement of the unlocking member 53 and the drive member 54 will not interfere with each other.

[0078] Please see Figure 1 , Figure 16 and Figure 18In one embodiment, the locking assembly 50 further includes a second reset member 56. The driving member 54 is connected to the bracket 51 via the second reset member 56, which drives the driving member 54 to rotate and reset. Thus, during the process of adjusting the position of the locking member 52 by pushing the driving member 54 to rotate, the reset force of the second reset member 56 enables the driving member 54 to quickly reset, thereby allowing for rapid adjustment of the position of the locking member 52.

[0079] Furthermore, when the second reset member 56 drives the drive member 54 to rotate and reset, the first force-applying part 5411 of the drive member 54 abuts against the locking part 521. In this reset state, its function is the same as that of the unlocking member 53, that is, it locks and fixes the locking member 52, preventing the locking member 52 and the pad 30 connected to it from loosening from the back of the lower leg 60.

[0080] In one embodiment, the second reset member 56 is a torsion spring or an elastic block.

[0081] Please see Figure 1 In one embodiment, there are two locking components 50, which are respectively disposed on both sides of the first fixing part 20. The locking member 52 of one locking component 50 is connected to one side of the pad 30, and the locking member 52 of the other locking component 50 is connected to the other side of the pad 30. In this way, the locking members 52 of the two locking components 50 are respectively connected to the opposite sides of the pad 30. By driving the locking member 52 to move, the pad 30 can be adjusted to be firmly attached to the back of the calf 60, providing support for the back of the calf 60.

[0082] Please see Figure 1 , Figure 16 and Figure 18 Specifically, the pad 30 has a mounting portion 31 on its side, and the end of the locking member 52 is detachably mounted on the mounting portion 31. Furthermore, the pad 30 may be provided with a fixing rod 32, which can be abutted against and fixed to the back of the ligament patient's lower leg 60. The relevant dimensional parameters of the fixing rod 32 are set according to the actual situation of the ligament patient and are not limited here.

[0083] Please see Figure 1 and Figure 7In one embodiment, the first fixing part 20 includes two first frame edges 21 and a first connecting plate 22 connecting the two first frame edges 21. The two first frame edges 21 are respectively used to fit against the left and right sides of the lower leg 60. The first connecting plate 22 is an arc-shaped plate used to fit against the front of the lower leg 60. Two locking components 50 are respectively disposed on the two first frame edges 21. Thus, after the first fixing part 20 is sleeved on the lower leg 60, the two first frame edges 21 fit against the left and right sides of the lower leg 60 respectively, and the first connecting plate 22 fits against the front of the lower leg 60. In this way, when the pad 30 is tightly attached to the back of the lower leg 60, the first fixing part 20 can achieve a good fixing effect on the lower leg 60. In addition, after the locking component 52 releases the pad 30, the first fixing part 20 can be easily removed from the lower leg 60, and the disassembly and assembly efficiency is high.

[0084] Please see Figure 1 and Figure 7 In one embodiment, the first fixing part 20 further includes at least one first strap 23. The two ends of the first strap 23 are respectively connected to two first frame edges 21. Thus, when the first fixing part 20 is installed on the lower leg 60, the first strap 23 fits against the front of the lower leg 60, which helps to securely fix the first fixing part 20 to the lower leg 60, while also making disassembly and assembly convenient and quick.

[0085] It should be noted that, in order to ensure the supporting and fixing effect of the first fixing part 20 on the lower leg 60, both the first frame edge 21 and the first connecting plate 22 are rigid components. In addition, the first strap 23 is a soft strap or elastic strap.

[0086] It should also be noted that the "first frame edge 21" can be a "part of the first connecting plate 22", that is, the "first frame edge 21" and the "other parts of the first connecting plate 22" are integrally formed; or it can be a separate component that can be separated from the "other parts of the first connecting plate 22", that is, the "first frame edge 21" can be manufactured independently and then combined with the "other parts of the first connecting plate 22" to form a whole. Figure 1 As shown, in one embodiment, the "first frame edge 21" is integrally formed as part of the "first connecting plate 22".

[0087] As an alternative, the first fixing part 20 is not limited to the combination of the two first frame edges 21 and the first connecting plate 22 mentioned above. For example, it can also be an arc-shaped plate or other structural plate that is fitted onto the front and side of the lower leg 60, as long as it can be worn on the lower leg 60.

[0088] Please see Figure 1 , Figure 3 and Figure 7In one embodiment, the second fixing part 40 includes two second frame edges 41 and a second connecting plate 42 connecting the two second frame edges 41. The two second frame edges 41 are respectively used to fit against the left and right sides of the thigh 70; the second connecting plate 42 is an arc-shaped plate used to fit against the back of the thigh 70. Thus, after the second fixing part 40 is sleeved on the thigh 70, the two second frame edges 41 fit against the left and right sides of the thigh 70 respectively, and the second connecting plate 42 fits against the back of the thigh 70. This achieves a better fixing effect of the second fixing part 40 on the thigh 70; in addition, it also facilitates the removal of the second fixing part 40 from the thigh 70, resulting in high disassembly and assembly efficiency.

[0089] Please see Figure 1 , Figure 3 and Figure 7 In one embodiment, the second fixing part 40 further includes at least one second strap 43, with both ends of the second strap 43 connected to two second frame edges 41 respectively. Thus, when the second fixing part 40 is installed on the thigh 70, the second strap 43 fits against the front of the thigh 70, which helps to securely fix the second fixing part 40 to the thigh 70, while also making disassembly and assembly convenient and quick.

[0090] It should be noted that, in order to ensure the supporting and fixing effect of the second fixing part 40 on the lower leg 60, both the second frame edge 41 and the second connecting plate 42 are rigid components. In addition, the second strap 43 is a soft strap or elastic strap.

[0091] It should also be noted that the "second frame edge 41" can be a "part of the second connecting plate 42", that is, the "second frame edge 41" and the "other parts of the second connecting plate 42" are integrally formed; or it can be a separate component that can be separated from the "other parts of the second connecting plate 42", that is, the "second frame edge 41" can be manufactured independently and then combined with the "other parts of the second connecting plate 42" to form a whole. Figure 1 As shown, in one embodiment, the "second frame edge 41" is integrally formed as part of the "second connecting plate 42".

[0092] As an alternative, the second fixing part 40 is not limited to the combination of the two second frame edges 41 and the second connecting plate 42 mentioned above. For example, it can also be an arc-shaped plate or other structural plate that is fitted onto the front and side of the thigh 70, as long as it can be worn on the thigh 70.

[0093] Please see Figure 1 , Figure 3 and Figure 7In one embodiment, there are two movable components 10. The frame edge of one side of the first fixing part 20 is connected to the frame edge of one side of the second fixing part 40 through one of the movable components 10, and the frame edge of the other side of the first fixing part 20 is connected to the frame edge of the second fixing part 40 through the other movable component 10.
