Description

Technical Field

[0001] The invention relates to the technical field of medical appliances, and in particular to a functional training brace after rotator cuff injury surgery. Background Art

[0002] Rehabilitation after rotator cuff surgery is a process of gradually restoring shoulder function, and usually requires following the guidance of a doctor or physical therapist. The rehabilitation plan is designed to help restore the range of motion, strength, and stability of the shoulder joint, while reducing pain and preventing re-injury. There will be different exercise methods at different stages of rotator cuff injury recovery. For example, in the initial stage, the main focus is on support and protection of the rotator cuff and passive exercise; in the middle stage, patients are required to actively exercise, increase the range of motion of the rotator cuff, and perform shoulder flexion, abduction, adduction and other movements; in the later stage, the main focus is strength training to enhance the stability and coordination of the shoulder joint.

[0003] Functional exercise is very important for patients after rotator cuff surgery. However, in actual practice, most patients are afraid of pain and their family members are unprofessional and do not trust their family members. During postoperative training, many patients dare not exercise, which leads to adverse consequences such as joint adhesion.

[0004] There are braces for training after rotator cuff injuries on the market, but their functions are relatively simple. They can either only support and protect the rotator cuff from further injury, or can only perform forward flexion alone. They do not take into account the abduction and adduction training of the rotator cuff during the recovery process, nor do they take into account the three stages of rehabilitation required after rotator cuff surgery. Therefore, existing braces cannot simultaneously meet the training needs of the three different stages of postoperative rehabilitation. Summary of the invention

[0005] The purpose of the present invention is to provide a functional training brace for rotator cuff injury surgery to solve the technical problem that the existing brace in the prior art cannot simultaneously meet the training needs of three different stages of postoperative rehabilitation.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions:

[0007] A functional training brace after rotator cuff injury surgery, comprising:

[0008] A trunk fixing plate is fixed on the patient's trunk, wherein a horizontally arranged arc track is provided on the trunk fixing plate, a vertical plate sliding along the arc track is provided on the arc track, and a vertical track is provided on the vertical plate;

[0009] An upper arm fixation plate is fixed on the patient's affected upper arm;

[0010] Among them, the vertical plate and the upper arm fixing plate are connected by a connecting plate, so that when the upper arm fixing plate is driven by an external force, the end of the connecting plate is driven to slide on the vertical track to adjust the angle between the upper arm fixing plate and the trunk fixing plate, thereby changing the height at which the patient's affected limb is lifted, and when the upper arm fixing plate is driven by an external force, the vertical plate is driven to slide on the arc track, so that the upper arm fixing plate drives the patient's affected limb to rotate in the horizontal direction.

[0011] Furthermore, the sliding range of the vertical plate on the curved track is adjustable and can be fixed to the curved track;

[0012] The sliding range of the end of the connecting plate on the vertical track is adjustable and can be fixed to the vertical plate;

[0013] Wherein, the end of the connecting plate is fixed at different heights to the vertical track, so that the patient's affected limb can rotate horizontally within the sliding range of the arc track at different heights;

[0014] By fixing the vertical plate and the arc track at different horizontal positions, the patient's affected limb can be rotated up and down within the sliding range of the vertical track at different horizontal positions.

[0015] Furthermore, a vertical slider is connected to the vertical track for sliding up and down movement, and both ends of the connecting plate are respectively hinged to the vertical slider and the upper arm fixing plate, so that when the upper arm fixing plate is swung up and down with the shoulder joint as the axis, the vertical slider slides inside the vertical track;

[0016] An arc-shaped slider is horizontally slidably connected inside the arc-shaped track, and the vertical plate is connected to the arc-shaped slider, so that when the upper arm fixing plate is horizontally swung with the shoulder joint as the axis, the vertical plate drives the arc-shaped slider to slide inside the arc-shaped track.

[0017] Furthermore, limit blocks are provided on both sides of the vertical slider and the arc-shaped slider;

[0018] The limit blocks on both sides of the vertical slide block are slidably connected to the vertical track and fixed by screws on the limit blocks. The height of the affected limb in the upper arm fixing plate is limited by adjusting the distance between the limit blocks and the vertical slide block;

[0019] The limit blocks on both sides of the arc-shaped slider are slidably connected to the arc track and fixed by screws on the limit blocks. The angle range of horizontal rotation of the affected limb in the upper arm fixing plate is limited by adjusting the distance between the limit blocks and the arc-shaped slider.

[0020] Furthermore, an angle scale line is provided on one side of the arc track to indicate the horizontal position of the inner limit block of the arc track;

[0021] A height scale line is arranged on one side of the vertical track to indicate the height position of the internal limit block of the vertical track.

[0022] Furthermore, a spring is detachably connected between the vertical slider and the limit block and between the arc-shaped slider and the limit block, so that when the vertical slider slides inside the vertical track and when the arc-shaped slider slides inside the arc-shaped track, the rebound force of the spring needs to be overcome;

[0023] Both ends of the spring are fixedly connected with clamping blocks, and clamping grooves are arranged on both sides of the vertical slider and both sides of the arc-shaped slider, as well as on one side of the limit block close to the spring, and the clamping blocks are clamped with the clamping grooves.

[0024] Furthermore, an arc-shaped placement groove is provided at the top of the upper arm fixing plate, an arc-shaped rotating plate is coaxially provided inside the arc-shaped placement groove, a rotating slider is fixedly connected to the bottom of the rotating plate, and a sliding groove is provided at the top of the placement groove. The rotating plate rotates along its central axis under the drive of external force, so that the rotating slider slides inside the sliding groove, thereby causing the affected limb inside the arc-shaped placement groove to rotate, and the rotating slider is fixed to the upper arm fixing plate by screws.

[0025] Furthermore, a forearm support plate for supporting the forearm and palm of the affected limb is horizontally rotatably connected to one side of the upper arm fixing plate, and the forearm support plate rotates under the action of external force to form an angle with the upper arm fixing plate.

[0026] Furthermore, a circular track is provided on the outside of the trunk fixing plate, the circular track is arranged at the bottom of the arc track, the vertical plate is connected to the circular track, and when the upper arm fixing plate is driven by an external force, the vertical plate is driven to slide on the circular track, so that the upper arm fixing plate drives the patient's affected limb to rotate in the vertical direction.

[0027] Furthermore, an annular slider is slidably connected inside the annular track, slots are provided on the outside of the annular slider and the outside of the arc-shaped slider, and an insert block is fixedly connected to the back of the vertical plate. Through the insert block and the slot, the vertical plate and the annular slider are detachably connected, and the vertical plate and the arc-shaped slider are detachably connected.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The present invention can provide patients with early support and protection, passive exercise, and different types of active exercise in the middle stage. It can perform flexion, abduction, adduction and other movements of the shoulder joint, as well as late strength training.

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1 and Figure 2 As shown, the present invention provides a functional training brace after rotator cuff injury surgery, comprising:

[0042] A trunk fixing plate 1 is fixed on the patient's trunk, a horizontally arranged arc track 2 is provided on the trunk fixing plate 1, a vertical plate 3 sliding along the arc track 2 is provided on the arc track 2, and a vertical track 4 is provided on the vertical plate 3;

[0043] An upper arm fixing plate 5, fixed on the patient's affected upper arm;

[0044] Among them, the vertical plate 3 and the upper arm fixing plate 5 are connected by a connecting plate 6, so that when the upper arm fixing plate 5 is driven by an external force, the end of the connecting plate 6 is driven to slide on the vertical track 4 to adjust the angle between the upper arm fixing plate 5 and the trunk fixing plate 1, thereby changing the height at which the patient's affected limb is lifted, and when the upper arm fixing plate 5 is driven by an external force, the vertical plate 3 is driven to slide on the arc track 2, so that the upper arm fixing plate 5 drives the patient's affected limb to rotate in the horizontal direction.

[0045] Specifically, Figure 4 and Figure 5 As shown, a vertical slider 7 is connected to the vertical track 4 for sliding up and down, and both ends of the connecting plate 6 are respectively hinged to the vertical slider 7 and the upper arm fixing plate 5, so that when the upper arm fixing plate 5 is swung up and down with the shoulder joint as the axis, the vertical slider 7 slides inside the vertical track 4;

[0046] An arc-shaped slider 8 is horizontally slidably connected inside the arc-shaped track 2, and the vertical plate 3 is connected to the arc-shaped slider 8, so that when the upper arm fixing plate 5 is horizontally swung with the shoulder joint as the axis, the vertical plate 3 drives the arc-shaped slider 8 to slide inside the arc-shaped track 2.

[0047] Functional exercise is very important for patients after rotator cuff surgery, but patients generally dare not exercise alone and need the help of a brace. However, the current braces have relatively single functions. They can either only support and protect the rotator cuff from further injury, or can only perform flexion alone. They do not consider the abduction and adduction exercises of the rotator cuff during the recovery process, nor do they consider that the three stages of rehabilitation after rotator cuff surgery are required. Therefore, the existing braces cannot simultaneously meet the three different stages of rehabilitation exercises after surgery. Therefore, it is very necessary to develop a brace that can simultaneously meet the three different stages of rehabilitation exercises after surgery.

[0048] This implementation method can provide patients with early support and protection, passive exercise, and different types of active exercise in the mid-term. It can perform shoulder flexion, abduction, adduction and other movements, as well as late strength training. It can simultaneously meet the three different stages of postoperative rehabilitation, assist in functional exercise for patients after rotator cuff injury surgery, achieve effective exercise, and prevent joint adhesion.

[0049] In actual use, 1. fix the trunk fixing plate 1 on the trunk on the side of the affected limb, and the trunk fixing plate 1 is provided with a strap to increase the firmness;

[0050] 2. Fix the upper arm fixation plate 5 on the patient's affected upper arm;

[0051] 3. According to the different stages of postoperative recovery of patients:

[0052] If it is the early protection stage, it is only necessary to fix the upper arm of the affected limb by the upper arm fixing plate 5 to prevent the affected limb from moving;

[0053] In the early passive exercise stage, the upper arm fixing plate 5 is swung up and down by external force to make the end of the connecting plate 6 slide on the vertical track 4 to adjust the angle between the upper arm fixing plate 5 and the trunk fixing plate 1, thereby changing the height at which the patient's affected limb is lifted, and the upper arm fixing plate 5 is swung left and right to make the vertical plate 3 slide on the arc track 2, so that the upper arm fixing plate 5 drives the patient's affected limb to rotate in the horizontal direction, thereby achieving the passive exercise effect and completing the exercises of foredrive, abduction and adduction;

[0054] If it is the middle active exercise stage, the patient actively exerts force to complete the above exercises;

[0055] If it is the later stage of strength training, strength training of the affected limb is performed by applying resistance.

[0056] There will be different exercise methods and different ranges of motion at different stages of rotator cuff injury recovery. Therefore, it is necessary to limit the lifting height and horizontal rotation angle of the affected limb to prevent secondary injury during exercise.

[0057] As a preferred embodiment of this embodiment, the sliding range of the vertical plate 3 on the arc track 2 is adjustable, and can be fixed to the arc track 2;

[0058] The sliding range of the end of the connecting plate 6 on the vertical track 4 is adjustable, and can be fixed to the vertical plate 3;

[0059] Wherein, the end of the connecting plate 6 is fixed to different heights of the vertical track 4, so that the patient's affected limb can rotate horizontally within the sliding range of the arc track 2 at different heights;

[0060] The vertical plate 3 and the arc track 2 are fixed at different horizontal positions, so that the patient's affected limb can rotate up and down within the sliding range of the vertical track 4 at different horizontal positions.

[0061] By limiting the lifting height and horizontal rotation angle of the affected limb, patients can adjust the brace by themselves to perform standardized exercises without causing secondary injuries due to excessive range of motion. Compared with the situation without the help of a brace, patients are more bold, can perform the exercise movements properly, and have better exercise effects.

[0062] Through adjustment, the affected limb can be rotated horizontally within the sliding range of the arc track 2 at different heights, and the affected limb can be rotated up and down within the sliding range of the vertical track 4 at different horizontal positions. The overall exercise range is large, fits the actual range of activities, and is beneficial to the patient's recovery.

[0063] The specific structure for limiting the lifting height and horizontal rotation angle of the affected limb is as follows: Figure 4 and Figure 5 As shown, limit blocks 9 are provided on both sides of the vertical slider 7 and the arc-shaped slider 8;

[0064] The limit blocks 9 on both sides of the vertical slide block 7 are slidably connected to the vertical track 4 and fixed by screws on the limit blocks 9. The height of the affected limb in the upper arm fixing plate 5 is limited by adjusting the distance between the limit blocks 9 and the vertical slide block 7;

[0065] The limit blocks 9 on both sides of the arc-shaped slider 8 are slidably connected to the arc track 2 and fixed by screws on the limit blocks 9. The angle range of horizontal rotation of the affected limb in the upper arm fixing plate 5 is limited by adjusting the distance between the limit blocks 9 and the arc-shaped slider 8.

[0066] By moving the limit block 9, adjusting the position of the limit block 9, and finally fixing the limit block 9, the sliding range of the vertical slider 7 in the vertical track 4 is limited, and the sliding range of the arc slider 8 in the arc track 2 is limited.

[0067] Specifically, in order to quantitatively adjust the limit block 9 according to the patient's recovery stage, an angle scale line 10 is provided on one side of the arc track 2 to indicate the horizontal position of the limit block 9 inside the arc track 2;

[0068] A height scale line 11 is provided on one side of the vertical track 4 to indicate the height position of the internal limit block 9 of the vertical track 4 .

[0069] According to the doctor's instructions, at different recovery stages of the patient, the limit block 9 is adjusted to be flush with the corresponding angle scale line 10 and height scale line 11, so that the patient can quantitatively adjust the range of motion of the affected limb, and the brace can correspond to the different recovery stages of the patient, making it more convenient to use.

[0070] In the later stage of strength training, it is necessary to perform strength training on the affected limb by applying resistance, specifically, Figure 4-6As shown, a spring 12 is detachably connected between the vertical slider 7 and the limit block 9 and between the arc-shaped slider 8 and the limit block 9, so that when the vertical slider 7 slides inside the vertical track 4, and when the arc-shaped slider 8 slides inside the arc-shaped track 2, the rebound force of the spring 12 needs to be overcome; when the patient swings the affected limb up and down, and swings the affected limb left and right for exercise, the rebound force of the spring 12 needs to be overcome, which helps the patient to exercise strength, so that the device can meet the exercise requirements of three different recovery stages.

[0071] Both ends of the spring 12 are fixedly connected with a clamping block 13 , and both sides of the vertical slider 7 and the arc slider 8 , as well as a side of the limit block 9 close to the spring 12 are provided with a clamping groove 14 , and the clamping block 13 is clamped with the clamping groove 14 .

[0072] The block 13 is connected with the slot 14 to facilitate installation and removal of the spring 12. It can be decided whether to install the spring 12 or replace the spring 12 with different elastic forces according to the recovery situation, so that the device has multiple exercise modes.

[0073] In actual activities, the upper limbs need to rotate left and right, but the current braces ignore this exercise. In order to exercise this function of the affected limb, specifically, Figure 7 As shown, an arc-shaped placement groove 15 is provided on the top of the upper arm fixing plate 5, an arc-shaped rotating plate 16 is coaxially provided inside the arc-shaped placement groove 15, a rotating slider 17 is fixedly connected to the bottom of the rotating plate 16, and a slide groove 18 is provided on the top of the placement groove. The rotating plate 16 rotates along its central axis under the drive of an external force, so that the rotating slider 17 slides inside the slide groove 18, thereby causing the affected limb inside the arc-shaped placement groove 15 to rotate, and the rotating slider 17 is fixed to the upper arm fixing plate 5 by screws.

[0074] During specific use, the affected limb is placed inside the rotating plate 16 and fixed with the straps on the rotating plate 16. Through external force or force exerted by the affected limb, the affected limb rotates and drives the rotating plate 16 to rotate inside the upper arm fixing plate 5, thereby achieving the purpose of exercise.

[0075] Due to the existence of the elbow joint, the patient's upper arm and forearm need to constantly adjust their angles. Figure 1 and Figure 2 As shown, a forearm support plate 19 for supporting the forearm and palm of the affected limb is horizontally rotatably connected to one side of the upper arm fixing plate 5 . The forearm support plate 19 rotates under the action of external force to form an angle with the upper arm fixing plate 5 .

[0076] According to the patient's recovery stage, especially in the early protection stage, the angle between the forearm support plate 19 and the upper arm fixing plate 5 is adjusted so that a fixed angle is formed between the upper arm and the forearm of the affected limb, which is convenient for fixing and stabilizing the affected limb and is beneficial to the patient's recovery. At the same time, by continuously adjusting the angle between the forearm support plate 19 and the upper arm fixing plate 5, the angle between the patient's upper arm and forearm can be continuously adjusted, which is beneficial to the patient's exercise recovery.

[0077] During the postoperative exercise recovery process of rotator cuff injury, shoulder shrug exercise is also needed to restore the daily function of the rotator cuff. However, this functional exercise is not considered in the current brace. In order to facilitate patients to perform shoulder shrug exercises, specifically, Figure 1 and Figure 3 As shown, a circular track 20 is provided on the outside of the trunk fixing plate 1, and the circular track 20 is arranged at the bottom of the arc track 2. The vertical plate 3 is connected to the circular track 20. When the upper arm fixing plate 5 is driven by an external force, the vertical plate 3 is driven to slide on the circular track 20, so that the upper arm fixing plate 5 drives the patient's affected limb to rotate in the vertical direction. The rotator cuff is rotated in the vertical direction by an external force or the rotator cuff itself, and the vertical plate 3 is caused to slide on the circular track 20 at the same time.

[0078] Specifically, it is convenient to connect the vertical plate 3 with the arc track 2 and the circular track 20 respectively. Figure 3 As shown, the annular track 20 is slidably connected with an annular slider 21, and slots are provided on the outside of the annular slider 21 and the outside of the arc-shaped slider 8. The back of the vertical plate 3 is fixedly connected with an insert block, and the vertical plate 3 is detachably connected to the annular slider 21 and the vertical plate 3 is detachably connected to the arc-shaped slider 8 through the insert block and the slot. When different exercise methods are required, the vertical plate 3 is connected to the arc-shaped slider 8 and the annular slider 21 respectively, so that the affected limb can rotate horizontally and vertically respectively, thereby expanding the use range of the device and facilitating use.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
