[0022] This invention provides a multifunctional rehabilitation brace for joint surgery, such as... Figures 1-3 As shown, the postoperative multifunctional rehabilitation brace for joints includes: a first shell 1, a second shell 5, a protective shell 11, and connecting components. Two connecting components are symmetrically arranged; the two sides of the first shell 1 and the second shell 5 are respectively connected by two connecting components, and the two sides of the protective shell 11 are respectively connected to the middle positions of the two connecting components.

[0023] Specifically, each of the connecting components includes a connecting frame 10, a first insert 17, and a second insert 16. The lower end of the first insert 17 is connected to the upper end of the second insert 16, and one end of the connecting frame 10 is connected to the outer wall of the second insert 16 near its upper end. The two sides of the first housing 1 are respectively connected to the upper ends of the two first inserts 17, and the two sides of the second housing 5 are respectively connected to the lower ends of the two second inserts 16; the two sides of the protective shell 11 are respectively connected to the other ends of the two connecting frames 10.

[0024] This multifunctional rehabilitation brace provides stable external support and protection for the knee joint after surgery, while also serving corrective, assisted movement, and training functions. When worn, the first shell 1 is fitted onto the thigh, and the second shell 2 is fitted onto the calf. The two connecting points of the two first inserts 17 and the two second inserts 16 are located on the left and right sides of the knee joint, respectively. In the description of this invention, all directional terms are based on the orientation of the multifunctional rehabilitation brace when normally worn on the human body and are consistent with the body's own orientation reference. For example, "front" refers to the direction facing the front of the body, and "back" refers to the direction facing the back of the body; "outer wall" refers to the surface of the component away from the body in normal use, and correspondingly, "inner wall" refers to the surface of the component close to or facing the body in normal use, and so on for other directions.

[0025] A first inner groove 3 is fixedly provided on both sides of the outer wall of the first housing 1. The first inner groove 3 is a groove-shaped structure with a downward opening. Each first insert 17 is slidably disposed inside the corresponding first inner groove 3, and after being adjusted to a suitable position, it is fixedly connected to the corresponding first inner groove 3 by connecting fasteners.

[0026] Specifically, each of the first inner slide grooves 3 has a mounting hole on its outer wall, and each of the first insert blocks 17 has multiple first positioning holes distributed along the axial direction of the first insert block 17. After each first insert block 17 is slidably adjusted to a suitable position inside its corresponding first inner slide groove 3, the mounting holes on each of the first inner slide grooves 3 are aligned with the corresponding first positioning holes on each of the first insert blocks 17. Then, connecting fasteners are passed through the aligned mounting holes and first positioning holes to fix each of the first insert blocks 17 and each of the first inner slide grooves 3.

[0027] Please continue reading Figures 1-3 Each of the two outer walls of the second housing 5 is fixedly provided with a second inner sliding groove 12, which is an upward-opening groove-shaped structure. Each of the second inserts 16 is slidably disposed inside the corresponding second inner sliding groove 12, and after being adjusted to a suitable position, is fixedly connected to the corresponding second inner sliding groove 12 by connecting fasteners.

[0028] Specifically, each of the second inner slide grooves 12 has a mounting hole on its outer wall, and each of the second insert blocks 16 has a plurality of first positioning holes distributed along the axial direction of the second insert block 16. After each second insert block 16 is slidably adjusted to a suitable position inside the corresponding second inner slide groove 12, the mounting holes on each of the second inner slide grooves 12 are aligned with the corresponding first positioning holes on each of the second insert blocks 16. Then, connecting fasteners are passed through the aligned mounting holes and the first positioning holes to fix each of the second insert blocks 16 and each of the second inner slide grooves 12.

[0029] In this specific embodiment, the connecting fastener is a bolt.

[0030] With the above design, patients can easily adjust the height of the multifunctional rehabilitation brace according to their own height. Since different patients have different heights, when using the multifunctional rehabilitation brace, unscrew the two connecting fasteners around the two second inner sliding grooves 12 and the two first inner sliding grooves 3, slide the two first inserts 17 into the positions inside the two first inner sliding grooves 3, and the two second inserts 16 into the positions inside the two second inner sliding grooves 12, adjust to the appropriate position, and then re-secure it using the multiple connecting fasteners.

[0031] Furthermore, such as Figure 1 , Figure 4 and Figure 5As shown, a hinge base 13 is fixedly provided on the upper surface of each second insert 16, and each hinge base 13 has a hole 15 on its front edge and rear edge respectively. A hinge head 19 is fixedly provided on the lower surface of each first insert 17, and a plurality of second positioning holes 20 are provided on the front edge of each hinge head 19, and a semi-circular groove 18 is provided on the rear edge of each hinge head 19.

[0032] Each hinge base 13 is hinged to a corresponding hinge head 19 via a magnetic pin 14. Specifically, each magnetic pin 14 is disposed inside one of the two holes 15 of a hinge base 13; the hole 15 at the front edge of the hinge base 13 engages with one of the plurality of second positioning holes 20 on the hinge head 19. When each magnetic pin 14 is disposed inside the hole 15 at the front edge of the hinge base 13, the end of each magnetic pin 14 can be selectively inserted into one of the plurality of second positioning holes 20 to achieve fixation. By engaging with different second positioning holes 20, the bending angle of the brace at the knee joint can be changed and fixed; the hole 15 at the rear edge of the hinge base 13 engages with the semi-circular groove 18 on the hinge head 19. When each magnetic pin 14 is disposed inside the hole 15 at the rear edge of the hinge base 13, the end of each magnetic pin 14 is slidably disposed inside the semi-circular groove 18 to achieve rotation.

[0033] With the above design, patients can adjust the multifunctional rehabilitation brace according to their rehabilitation progress and medical advice to set a safe range of joint movement. By inserting the two magnetic pins 14 into the two suitable second positioning holes 20, the angle of the brace can be fixed. When the two magnetic pins 14 are inserted into the two semi-circular grooves 18, the brace can be rotated at the knee joint.

[0034] Furthermore, such as Figures 1-3 As shown, both the first shell 1 and the second shell 2 are arc-shaped shells with a circular arc cross-section, and their dimensions vary along the axial direction, specifically designed according to the size of the wearer's thigh and calf. When worn, the first shell 1 is placed at the front of the thigh, and the second shell 2 is placed at the front of the calf.

[0035] In this specific embodiment, both the first housing 1 and the second housing 2 are plastic housings. In other embodiments, the first housing 1 and the second housing 2 may be made of other materials.

[0036] A first fabric strap 2 is fixedly connected to each of the two rear ends of the first housing 1. Multiple first buckles 4 are fixedly provided at the junction of the two first fabric straps 2. By fastening the multiple first buckles 4, the two first fabric straps 2 are connected together, thereby fixing the first housing 1 to be worn on the thigh. A second fabric strap 6 is fixedly connected to each of the two rear ends of the second housing 5. Multiple second buckles 7 are fixedly provided at the junction of the two second fabric straps 6. By fastening the multiple second buckles 7, the two second fabric straps 6 are connected together, thereby fixing the second housing 5 to be worn on the calf.

[0037] In this specific embodiment, there are two of each of the first female buckle 4 and the second female buckle 7.

[0038] For further information, please continue reading. Figures 1-3 Airbags 8 are fixedly installed on the front inner walls of the first shell 1 and the second shell 5, and miniature air pumps 9 are fixedly installed on the front outer walls of the first shell 1 and the second shell 5, respectively. The two miniature air pumps 9 are connected to the two airbags 8.

[0039] After the patient has put on the multifunctional rehabilitation brace, the two miniature air pumps 9 can be activated to inflate the two air bags 8 respectively, so that the multifunctional rehabilitation brace fits the patient's legs more closely. At the same time, the first shell 1 and the second shell 5 can be separated from the patient's thighs and calves, avoiding direct contact between the first shell 1 and the second shell 5 and the thighs and calves, which would compress the patient's soft tissues and cause the patient to feel pain.

[0040] For further information, please continue reading. Figures 1-3 Figures 1-3 The rear end of each connecting frame 10 is fixedly disposed on the outer wall of the corresponding second plug 16 near its upper end and extends forward of the second plug 16. The front end of each connecting frame 10 is fixedly connected to both sides of the protective shell 11, so that the protective shell 11 is located in front of the two second plugs 16.

[0041] With the above design, when the patient wears this multifunctional rehabilitation brace, the protective shell 11 is always located at the front end of the knee joint. When the patient leans forward and falls, the protective shell 11 is supported by the two connecting frames 10, which protects the knee joint and can prevent secondary damage to the knee joint caused by the fall.

[0042] In summary, when using the multifunctional rehabilitation brace in the above specific embodiments, the patient first adjusts the multifunctional rehabilitation brace according to their own height, unscrewing all the bolts on the outer walls of the two first inner sliding grooves 3 and the two second inner sliding grooves 12. Then, simultaneously slide and adjust the positions of the two first inserts 17 inside the two first inner sliding grooves 3 and simultaneously slide and adjust the positions of the two second inserts 16 inside the two second inner sliding grooves 12. After adjustment, re-fix with bolts. Subsequently, according to the rehabilitation situation and medical advice, adjust the multifunctional rehabilitation brace to set the safe range of joint movement, pull out the two magnetic pins 14 respectively, and then align two of the four holes 15 simultaneously with the two semi-circular grooves 18 or respectively with two of the multiple second positioning holes 20 on the two hinge heads 19. Then, insert the two magnetic pins 14 into the two holes 15 respectively. If two of the four holes 15 are aligned with the two semicircular slots 18 at the same time, and the two magnetic pins 14 are inserted into the two semicircular slots 18, the brace can be rotated at the knee joint. If two of the multiple second positioning holes 20 are selectively aligned and inserted, the bending angle of the brace is adjusted to a suitable position and then fixed.

[0043] After adjusting the height of the brace and the range of motion of the joints, open the two first snap fasteners 4 and the two second snap fasteners 7 respectively. Using the first fabric strap 2 and the second fabric strap 6, slip the brace over the thigh and calf, then fasten the two first snap fasteners 4 and the two second snap fasteners 7. Next, activate the two miniature air pumps 9 to inflate the two air bags 8 until they are in close contact with the thigh and calf respectively. Then, turn off the miniature air pumps 9 to stop inflation. Patients may experience fear while walking, making them prone to falls and secondary injuries. When using this device, the protective shell 11 remains positioned at the front of the patient's knee joint, preventing direct secondary injury to the knee joint in case of a forward fall.
