[0018] A method for using a bone and joint protection and treatment set for orthopedic treatment comprises the following steps:

[0019] S1. Wearing of the set:

[0020] The two upper fixing belts are covered on the front side of the patient's upper limbs, and the two lower fixing belts are covered on the front side of the patient's lower limbs. The first elastic belt and the second elastic belt are bonded together using the sub-velcro and the main Velcro at the end of each fixing belt, so that the fixing belt, the first elastic belt and the second elastic belt are worn in a ring shape on the patient's upper limbs and lower limbs, and the wearing of the set is completed;

[0021] S2. Exercise therapy for lower limbs:

[0022] When the patient's lower limbs are doing swing rehabilitation exercises, the lower limbs drive the rotating plate to rotate inside the arc groove through the fixed part below, and the rotating plate can drive the central rod to rotate when rotating;

[0023] When the patient's lower limb swings with a large amplitude, the rotation angle of the rotating plate is larger, and thus the rotation angle of the center rod is larger.

When the driven wheel rotates, it can drive the rotating rod to rotate synchronously. The rotating rod can drive the threaded sleeve rod sleeved on the rotating rod to rotate. Since the threads between the moving block and the threaded sleeve rod are matched, and the moving block is slidably arranged on the two guide rails, when the threaded sleeve rod rotates, it can drive the moving block to move. When the moving block moves, it can drive the locking block to move through the guide rod and the second spring, so that the locking block can move in the direction of the tapered block, and the locking block contacts the tapered block to increase the friction between the tapered block and the locking block, that is, when the lower limb rotation angle is larger, the friction between the locking block and the tapered block is larger, which can prevent the lower limb activity angle from being too large to affect the patient's bone and joint rehabilitation, and can ensure that the joint moves slowly, and prevent violent activities from causing damage to the joint.

[0024] S3. Disassembly and assembly of the set:

[0025] When the fixing part is damaged and needs to be replaced, the pull rods on both sides of the connecting seat are pulled to move the pull rods toward the side away from the connecting seat. When the pull rods move, they can drive the limit block to move out of the limit groove and into the avoidance groove. At this time, the first spring is compressed, and then the plug rod is taken out from the inside of the slot to realize the disassembly of the fixing part;

[0026] When installing the new fixing part, the limit block is moved into the avoidance groove in the same way. At this time, the insertion rod is inserted into the slot, and then the pull rod is loosened. Under the action of the first spring, the limit block can be driven to reset, so that the limit block can be inserted into the limit groove to lock the insertion rod, thereby realizing the installation of the fixing part without replacing the entire set.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The bone joint protection and treatment set for orthopedic treatment of the present invention and the use method thereof, when the patient's lower limbs move at an angle that is too large, that is, bend greatly, the protective mechanism provided can limit and block the large-scale bending movement of the patient's lower limbs to a certain extent. When the patient's lower limbs are exercised, the greater the bending movement angle, that is, the greater the movement range, the greater the resistance applied to the lower limbs simultaneously, which can prevent the patient from straining the limbs during exercise treatment and avoid the problem of the patient being easily injured during the rehabilitation period, realize autonomous training, and can ensure slow movement of the joints while avoiding the disadvantage of damage to the joints caused by large-scale bending activities.

[0029] 2. The bone and joint protection treatment set for orthopedic treatment of the present invention and the use method thereof, by setting a driving component, can achieve a linkage effect between the rotating component and the locking component, that is, when the rotating plate rotates, it can drive the locking block to move, and the greater the rotation angle of the rotating plate, the greater the contact area between the locking block and the conical block, thereby realizing adaptive adjustment of the size of the lower limb resistance when the patient's lower limb moves, which can effectively avoid the patient's large-scale movement during the rehabilitation period, and is conducive to ensuring the slow movement of the patient's joints.

[0030] 3. The bone joint protection and treatment set for orthopedic treatment of the present invention and the use method thereof, by providing an installation mechanism, enables the two fixing parts and the protection mechanism in the set to be disassembled and spliced. When a part of the set is damaged, the part can be directly disassembled, cleaned and replaced without replacing the entire set, which is beneficial to reducing the use cost of the set.

[0031] 4. The bone and joint protective treatment set for orthopedic treatment of the present invention and the use method thereof can be quickly worn on the patient's limbs by providing two fixing parts. By providing a first elastic band, a second elastic band, a child Velcro, a mother Velcro, etc., not only can the fit between the set and the patient be improved when worn, and it is convenient to adjust at any time according to the patient's habits and rehabilitation process, but also the set can be worn and used by patients of different body shapes, and has a wide range of applications.

Each rotating component is located between a center rod 30 and a rotating rod 31. Each locking component is installed on the center rod 30. Each driving component is located between a rotating component and a locking component.

[0045] During the patient's rehabilitation training treatment, when the patient's lower limbs move, the rotating plate 28 can be driven to rotate, and the rotating plate 28 can drive the central rod 30 to rotate, so that the rotating rod 31 can be driven to rotate under the action of the rotating component, and the locking component can be driven to work under the action of the driving component, so as to limit and block the large-scale bending activities of the patient's lower limbs to a certain extent, and solve the problem that the patient can prevent the patient from straining the limbs during the exercise treatment during the rehabilitation treatment, and avoid the problem that the patient is prone to injury during the rehabilitation period, realize autonomous training, ensure that the joints can move slowly, and at the same time avoid the disadvantages of large-scale bending activities causing damage to the joints;

[0046] The mounting mechanism includes four connecting seats 18, four plugging rods 25, four limiting components and four unlocking components, each connecting seat 18 is fixed to a side of a fixing portion 11 close to the outer shell 26, specifically, each connecting seat 18 is mounted on a first elastic band 13 on a side of each fixing portion 11 close to the outer shell 26, a slot 19 is provided on one side of each connecting seat 18, specifically, the slot 19 is provided on a side of the connecting seat 18 close to the outer shell 26, each plugging rod 25 is plugged into an interior of a slot 19, the two plugging rods 25 on the lower fixing portion 11 are fixedly connected to the two rotating plates 28, respectively, the two plugging rods 25 on the upper fixing portion 11 are fixedly connected to the two fixing plates 29, respectively, each limiting component is mounted between a connecting seat 18 and a plugging rod 25, and each unlocking component is mounted between a connecting seat 18 and an unlocking component;

[0047] The limiting assembly can be used to achieve the connection between the insertion rod 25 and the connecting seat 18, thereby achieving the connection between the protective mechanism and the two fixing parts 11, and realizing the assembly of the present set. The unlocking assembly can be used to release the connection between the connecting seat 18 and the insertion rod 25, thereby achieving the disassembly between the protective mechanism and the two fixing parts 11, and facilitating the maintenance of the present set.

[0048] like Figure 1-Figure 8 As shown, each rotating assembly includes a driving wheel 32, a driven wheel 33 and a transmission belt 34. The driving wheel 32 is located on one side of the rotating plate 28 and is fixed on the surface of the center rod 30. The driven wheel 33 is located above the driving wheel 32 and is fixed on the surface of the rotating rod 31. The transmission belt 34 is sleeved on the driving wheel 32 and the driven wheel 33.

[0049] When the patient's lower limbs are bent, the fixed part 11 on the lower limbs can move synchronously with the patient's lower limbs, thereby driving the rotating plate 28 to rotate inside the arc groove 27. The rotating plate 28 can drive the driving wheel 32 to rotate through the center rod 30, and can drive the driven wheel 33 to rotate under the action of the transmission belt 34, so that the rotating rod 31 can be rotated.

[0050] like Figure 1-Figure 8As shown, each locking assembly includes a conical block 40 and a locking block 41. The conical block 40 is located on the side of the rotating plate 28 away from the driving wheel 32, and the locking block 41 is located on one side of the conical block 40. The end of the locking block 41 close to the conical block 40 is in an arc shape that matches the surface of the conical block 40.

[0051] like Figure 1-Figure 8 As shown, each driving assembly includes a threaded sleeve 35, a moving block 36, a plurality of guide rods 38 and a plurality of second springs 39. The threaded sleeve 35 is fixedly sleeved on the surface of the rotating rod 31, the moving block 36 is sleeved on the threaded sleeve 35 and threadedly matched with the threaded sleeve 35, each guide rod 38 is slidably set on the moving block 36, and the bottom end of each guide rod 38 is fixedly connected to the locking block 41, each second spring 39 is sleeved on the outside of a guide rod 38, and both ends of each second spring 39 are connected to the moving block 36 and the locking block 41. It should be noted here that the side of the locking block 41 close to the conical block 40 is provided with an oblique angle for facilitating the locking block 41 to move to the top of the conical block 40.

[0052] like Figure 1-Figure 8 As shown, a guide rail 37 is provided on both sides of each moving block 36, each guide rail 37 is fixedly connected to the inner wall of the housing 26, and each moving block 36 is slidably disposed in the two guide rails 37;

[0053] When the rotating rod 31 rotates, the threaded sleeve 35 can be driven to rotate. Since the threaded sleeve 35 and the moving block 36 are threadedly matched, and the moving block 36 is slidably arranged on two guide rails 37, when the threaded sleeve 35 rotates with the rotating rod 31, the moving block 36 can be driven to move, and the moving block 36 can drive the locking block 41 to move toward the direction close to the conical block 40. Since the locking block 41 can be lifted and lowered under the action of the guide rod 38, the locking block 41 can move to the top of the conical block 40 with the movement of the moving block 36.

[0054] The greater the rotation angle of the rotating plate 28, the larger the contact area between the locking block 41 and the conical block 40, that is, the greater the bending angle of the patient's lower limbs and the more intense the activity, the greater the resistance to the lower limbs. This can solve the problem of patients achieving autonomous training during rehabilitation treatment and ensure that the joints can move slowly, while avoiding the disadvantage of large-scale bending activities causing damage to the joints.

[0055] like Figure 1-Figure 8As shown, each limit assembly includes two limit grooves 24, two limit blocks 23 and two avoidance grooves 20. The two limit grooves 24 are symmetrically opened on both sides of the insertion rod 25, and the two avoidance grooves 20 are symmetrically opened on both sides of the connecting seat 18. Each avoidance groove 20 is connected to the slot 19, and each avoidance groove 20 is located on one side of a limit groove 24. Each limit block 23 is slidably set inside an avoidance groove 20, and one end of each limit block 23 is inserted into the inside of a limit groove 24.

[0056] like Figure 1-Figure 8 As shown, each unlocking assembly includes two pull rods 21 and two first springs 22. The two pull rods 21 are respectively located on the sides of the two limit blocks 23 that are away from each other. Each pull rod 21 is slidably arranged on the connecting seat 18, and one end of each pull rod 21 is fixedly connected to a limit block 23. Each first spring 22 is sleeved on a pull rod 21, and both ends of each first spring 22 are fixedly connected to the limit block 23 and the connecting seat 18.

[0057] When the fixing part 11 is damaged and needs to be replaced, the pull rods 21 on both sides of the connecting seat 18 are pulled to move the pull rods 21 toward the side away from the connecting seat 18. When the pull rods 21 move, they can drive the limit block 23 to move, so that the limit block 23 can move out of the limit groove 24 and move into the avoidance groove 20. At this time, the first spring 22 is compressed, and then the insertion rod 25 is taken out from the inside of the slot 19 to realize the disassembly of the fixing part 11;

[0058] When installing the new fixing part 11, the limit block 23 is moved into the avoidance groove 20 in the same way. At this time, the insertion rod 25 is inserted into the inside of the slot 19, and then the pull rod 21 is loosened. Under the action of the first spring 22, the limit block 23 can be driven to reset, so that the limit block 23 can be inserted into the inside of the limit groove 24, thereby locking the insertion rod 25, thereby realizing the installation of the fixing part 11 without replacing the entire set.

[0059] like Figure 1-Figure 8 As shown, each fixing portion 11 includes two fixing straps 12, two connecting straps 17 and two tightening pieces. The two fixing straps 12 are arranged up and down, and the two connecting straps 17 are symmetrically arranged on both sides of the two fixing straps 12. Both ends of each connecting strap 17 are fixedly connected to the two fixing straps 12, and each tightening piece is located at the end of a fixing strap 12.

[0060] like Figure 1-Figure 8 As shown, each fastening member includes a first elastic band 13, a second elastic band 14, a sub-velcro 15 and a mother Velcro 16. The first elastic band 13 and the second elastic band 14 are respectively fixed to two ends of a fixing band 12, the sub-velcro 15 is arranged on one side of the first elastic band 13, and the mother Velcro 16 is arranged on one side of the second elastic band 14;

[0061] When the set needs to be worn, the two upper fixing belts 12 are covered on the front side of the patient's upper limbs, and the two lower fixing belts 12 are covered on the front side of the patient's lower limbs. The first elastic belt 13 and the second elastic belt 14 are adhered together by using the sub-velcro 15 and the main Velcro 16 at the end of each fixing belt 12, so that the fixing belts 12, the first elastic belt 13 and the second elastic belt 14 are worn in a ring shape on the patient's upper and lower limbs, and the wearing of the set is completed.

[0062] A method for using a bone and joint protection and treatment set for orthopedic treatment comprises the following steps:

[0063] S1. Wearing of the set:

[0064] The two upper fixing belts 12 are covered on the front side of the patient's upper limbs, and the two lower fixing belts 12 are covered on the front side of the patient's lower limbs. The first elastic belt 13 and the second elastic belt 14 are bonded together by using the sub-velcro 15 and the main Velcro 16 at the end of each fixing belt 12, so that the fixing belts 12, the first elastic belt 13 and the second elastic belt 14 are worn in a ring shape on the patient's upper limbs and lower limbs, and the wearing of the set is completed;

[0065] S2. Exercise therapy for lower limbs:

[0066] When the patient's lower limbs are doing swing rehabilitation exercises, the lower limbs drive the rotating plate 28 to rotate inside the arc groove 27 through the lower fixing part 11, and the rotating plate 28 can drive the central rod 30 to rotate when rotating;

[0067] When the patient's lower limb swings with a large amplitude, the rotation angle of the rotating plate 28 is larger, and thus the rotation angle of the center rod 30 is larger. When the center rod 30 rotates, it can drive the driving wheel 32 to rotate. Under the action of the transmission belt 34, when the driving wheel 32 rotates, it can drive the driven wheel 33 to rotate. When the driven wheel 33 rotates, it can drive the rotating rod 31 to rotate synchronously. The rotating rod 31 can drive the threaded sleeve rod 35 sleeved on the rotating rod 31 to rotate. Since the moving block 36 and the threaded sleeve rod 35 are threadedly matched, and the moving block 36 is slidably set on two guide rails 37, when the threaded sleeve rod 35 When rotating, the moving block 36 can be driven to move. When the moving block 36 moves, the locking block 41 can be driven to move through the guide rod 38 and the second spring 39, so that the locking block 41 can move toward the direction of the tapered block 40, and the locking block 41 contacts the tapered block 40, increasing the friction between the tapered block 40 and the locking block 41, that is, when the rotation angle of the lower limb is larger, the friction between the locking block 41 and the tapered block 40 is larger, which can prevent the lower limb from moving too much and affect the patient's bone and joint rehabilitation, and can ensure that the joint moves slowly, and prevent violent activities from causing damage to the joint;

[0068] S3. Disassembly and assembly of the set:

[0069] When the fixing part 11 is damaged and needs to be replaced, the pull rods 21 on both sides of the connecting seat 18 are pulled to move the pull rods 21 toward the side away from the connecting seat 18. When the pull rods 21 move, they can drive the limit block 23 to move, so that the limit block 23 can move out of the limit groove 24 and move into the avoidance groove 20. At this time, the first spring 22 is compressed, and then the insertion rod 25 is taken out from the inside of the slot 19 to realize the disassembly of the fixing part 11;

[0070] When installing the new fixing part 11, the limit block 23 is moved into the avoidance groove 20 in the same way. At this time, the insertion rod 25 is inserted into the inside of the slot 19, and then the pull rod 21 is loosened. Under the action of the first spring 22, the limit block 23 can be driven to reset, so that the limit block 23 can be inserted into the inside of the limit groove 24, thereby locking the insertion rod 25, thereby realizing the installation of the fixing part 11 without replacing the entire set.

[0071] The specific working process of the present invention is as follows:

[0072] The two upper fixing belts 12 are covered on the front side of the patient's upper limbs, and the two lower fixing belts 12 are covered on the front side of the patient's lower limbs. The first elastic belt 13 and the second elastic belt 14 are bonded together by using the sub-velcro 15 and the main Velcro 16 at the end of each fixing belt 12, so that the fixing belts 12, the first elastic belt 13 and the second elastic belt 14 are worn in a ring shape on the patient's upper limbs and lower limbs, and the wearing of the set is completed;

[0073] When the patient's lower limbs are doing swing rehabilitation exercises, the lower limbs drive the rotating plate 28 to rotate inside the arc groove 27 through the lower fixing part 11, and the rotating plate 28 can drive the central rod 30 to rotate when rotating;

[0074] When the patient's lower limb swings with a large amplitude, the rotation angle of the rotating plate 28 is larger, and thus the rotation angle of the center rod 30 is larger. When the center rod 30 rotates, it can drive the driving wheel 32 to rotate. Under the action of the transmission belt 34, when the driving wheel 32 rotates, it can drive the driven wheel 33 to rotate. When the driven wheel 33 rotates, it can drive the rotating rod 31 to rotate synchronously. The rotating rod 31 can drive the threaded sleeve rod 35 sleeved on the rotating rod 31 to rotate. Since the moving block 36 and the threaded sleeve rod 35 are threadedly matched, and the moving block 36 is slidably set on two guide rails 37, when the threaded sleeve rod 35 rotates, it can drive the moving block 36 to move. When the moving block 36 moves, it can drive the locking block 41 through the guide rod 38 and the second spring 39. The locking block 41 can be moved toward the direction of the tapered block 40, and because the locking block 41 can be lifted and lowered under the action of the guide rod 38, the locking block 41 can move to the top of the tapered block 40 with the movement of the moving block 36 and the locking block 41 contacts the tapered block 40, thereby increasing the friction between the tapered block 40 and the locking block 41, that is, when the rotation angle of the lower limb is larger, the friction between the locking block 41 and the tapered block 40 is larger, that is, the larger the bending activity angle of the patient's lower limb and the more intense the activity, the greater the resistance to the lower limb, which can solve the problem of patients realizing autonomous training during rehabilitation treatment, ensuring that the joints can move slowly, and at the same time avoiding the disadvantage of large-scale bending activities causing damage to the joints;

[0075] When the fixing part 11 is damaged and needs to be replaced, the pull rods 21 on both sides of the connecting seat 18 are pulled to move the pull rods 21 toward the side away from the connecting seat 18. When the pull rods 21 move, they can drive the limit block 23 to move, so that the limit block 23 can move out of the limit groove 24 and move into the avoidance groove 20. At this time, the first spring 22 is compressed, and then the insertion rod 25 is taken out from the inside of the slot 19 to realize the disassembly of the fixing part 11;

[0076] When installing the new fixing part 11, the limit block 23 is moved into the avoidance groove 20 in the same way. At this time, the insertion rod 25 is inserted into the inside of the slot 19, and then the pull rod 21 is loosened. Under the action of the first spring 22, the limit block 23 can be driven to reset, so that the limit block 23 can be inserted into the inside of the limit groove 24, thereby locking the insertion rod 25, thereby realizing the installation of the fixing part 11 without replacing the entire set.

[0077] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
