Description

Technical Field

[0001] The invention belongs to the technical field of bone correction medical devices, and in particular, relates to a dynamic correction brace for scoliosis. Background Art

[0002] Adolescent idiopathic scoliosis is a spinal deformity that occurs frequently in adolescents without a clear cause. The spine usually presents an "S" or "C" shaped lateral curvature with partial or overall twisting. Studies have shown that spinal deformity will continue to worsen with the patient's age, compressing organs and thus seriously affecting the patient's life. Therefore, external intervention for spinal deformity during adolescence is very necessary.

[0003] In the treatment of scoliosis, different treatment methods are used according to the different scoliosis angles (cobb angles). Corrective treatment is mainly used when the scoliosis angle is between 15° and 40°. Corrective treatment requires patients to wear corrective braces for a long time (generally more than 22 hours a day) so that the patient's spine is subjected to the force of the brace for a long time, thereby completing passive correction of the spine. After several months of long treatment, the degree of spinal deformity can be observed to be significantly reduced. However, the accumulated deformity of the patient's spine causes the surrounding tendons to be in a deformed state, which cannot be fully recovered through a single passive correction. Therefore, doctors generally encourage patients to perform specially choreographed gymnastics so that patients can train in an active correction manner.

[0004] However, in the prior art, neither the classic hard brace nor the dynamic brace can guarantee the correction effect while allowing the patient to move, lacks the possibility of lightweighting, and cannot meet the needs of patients for long-term wearing.

[0005] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0048] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] like Figure 1 to Figure 2 As shown, the present invention provides a dynamic correction brace for scoliosis, the dynamic correction brace for scoliosis comprises:

[0050] A crotch splint assembly, the crotch splint assembly is semi-enclosed and supported on both sides of the crotch of the human body;

[0051] The hip exoskeleton frame is located above the hip splint assembly, and the hip exoskeleton frame is connected to the hip splint assembly via a connecting assembly;

[0052] The rib exoskeleton frame 23 is located above the hip exoskeleton frame, and the hip exoskeleton frame is connected to the rib exoskeleton frame 23 via a first correction adjustment component;

[0053] The underarm exoskeleton frame 25 is located above the rib exoskeleton frame 23, and the underarm exoskeleton frame 25 is connected to the rib exoskeleton frame 23 via a second correction adjustment component;

[0054] By adjusting the first correction adjustment component and the second correction adjustment component, the underarm exoskeleton frame 25 and the rib exoskeleton frame 23 are driven to move with six degrees of freedom relative to the hip exoskeleton frame.

[0055] Specifically, the crotch splint assembly is semi-enclosed and supported on both sides of the human crotch, providing a fulcrum for the posture tracking of the dynamic correction brace for scoliosis. The crotch exoskeleton frame is connected to the crotch splint assembly through a connecting assembly, and the crotch exoskeleton frame is located above the crotch splint assembly. The crotch exoskeleton frame is connected to the rib exoskeleton frame 23 through a first correction adjustment assembly, and the rib exoskeleton frame 23 is located above the crotch exoskeleton frame. The underarm exoskeleton frame 25 is connected to the rib exoskeleton frame 23 through a second correction adjustment assembly, and the underarm exoskeleton frame 25 is located above the rib exoskeleton frame 23.

[0056] Through the segmented design of the hip exoskeleton frame, the rib exoskeleton frame 23, the underarm exoskeleton frame 25, and the customizable pad combination, the correction effect of the traditional brace is decomposed into three independent hip, rib, and underarm sections while retaining the correction effect of the traditional brace, thereby achieving dynamic correction of the dynamic brace.

[0057] The present invention provides a dynamic correction brace for scoliosis. By adjusting the first correction adjustment component and the second correction adjustment component, the axillary exoskeleton frame 25 and the rib exoskeleton frame 23 are driven to move with six degrees of freedom relative to the hip exoskeleton frame. Under high rigidity, dynamic adjustment is performed along with the patient's movement to achieve real-time tracking of the patient's posture. The structural design that conforms to the clinical correction mechanism can ensure that the patient is always subjected to the correct correction force. The lightweight design of the overall structure makes the dynamic correction brace for scoliosis have the potential for long-term wear.

[0058] Furthermore, the hip exoskeleton frame includes a left hip connector 19, a width adjustment member, and a right hip connector 20 which are connected in sequence.

[0059] The crotch splint assembly comprises a left crotch splint 17 and a right crotch splint 18, and the left crotch splint 17 and the right crotch splint 18 are supported on the left and right sides of the human crotch respectively.

[0060] The left crotch splint 17 is supported on the left side of the human crotch, and the right crotch splint 18 is supported on the right side of the human crotch. The left crotch splint 17 and the right crotch splint 18 are semi-enclosed and supported on both sides of the human crotch, providing a fulcrum for the posture tracking of the dynamic correction brace for scoliosis.

[0061] The left hip splint 17 is made of nylon material by 3D printing, and the surface is wrapped by a skin-friendly silicone film.

[0062] The right hip splint 18 is made of nylon material by 3D printing, and the surface is wrapped with a skin-friendly silicone film.

[0063] The hip exoskeleton frame comprises a left hip connection member 19, a width adjustment member, and a right hip connection member 20 which are connected in sequence.

[0064] The left hip connector 19 is made of nylon by 3D printing, and the surface is wrapped with a skin-friendly silicone film.

[0065] The width adjustment part is made of nylon by 3D printing and the surface is wrapped with a skin-friendly silicone film.

[0066] The right hip connector 20 is made of nylon material by 3D printing, and the surface is wrapped with a skin-friendly silicone film.

[0067] There can be multiple width adjustment pieces, each with a different length. Considering the differences in body shape between patients and the errors in body measurement, width adjustment pieces are designed to achieve the reuse of the hip exoskeleton frame for different body shapes. By replacing width adjustment pieces of different lengths, the adaptation range of the hip exoskeleton frame can be expanded, which can effectively improve the efficiency of customized dynamic braces for patients.

[0068] Furthermore, the connecting component is a screw rod 21 , the left hip splint 17 is connected to the left hip connector 19 via the screw rod 21 , and the right hip splint 18 is connected to the right hip connector 20 via the screw rod 21 .

[0069] Optionally, the left crotch splint 17 is rigidly connected to the left crotch connector 19 via two spaced apart threaded rods 21 , and the right crotch splint 18 is rigidly connected to the right crotch connector 20 via two spaced apart threaded rods 21 .

[0070] By adjusting the length and the installation angle of the screw rod 21, the position of the left crotch splint 17 relative to the left crotch connector 19 can be adjusted. The position of the right crotch splint 18 relative to the right crotch connector 20 can be adjusted.

[0071] In some optional embodiments, such as Figure 1 to Figure 2 As shown, the present invention provides a dynamic correction brace for scoliosis, wherein the first correction adjustment component of the dynamic correction brace for scoliosis includes a plurality of first pneumatic cylinders 22, the telescopic ends of the first pneumatic cylinders 22 are connected to the rib exoskeleton frame 23 through a universal coupling 16, and the bottom ends of the first pneumatic cylinders 22 are connected to the hip exoskeleton frame through a universal coupling 16;

[0072] A plurality of first pneumatic cylinders 22 are circumferentially spaced apart and distributed between the hip exoskeleton frame and the rib exoskeleton frame 23 .

[0073] Further, the second correction adjustment assembly includes a plurality of second pneumatic cylinders 24, the telescopic ends of the second pneumatic cylinders 24 are connected to the underarm exoskeleton frame 25 through the universal coupling 16, and the bottom ends of the second pneumatic cylinders 24 are connected to the rib exoskeleton frame 23 through the universal coupling 16;

[0074] A plurality of second pneumatic cylinders 24 are circumferentially spaced apart and distributed between the armpit exoskeleton frame 25 and the rib exoskeleton frame 23 .

[0075] The plurality of first pneumatic cylinders 22 and the plurality of second pneumatic cylinders 24 are independently connected to the pneumatic power supply device through corresponding air valves. The pneumatic power supply device can be a pneumatic pump. The pneumatic power supply device is placed indoors and the patient does not need to wear it. The pneumatic power supply device can control the telescopic length of each first pneumatic cylinder 22 and each second pneumatic cylinder 24 through the corresponding air valve.

[0076] Preferably, a hip exoskeleton frame that closely fits the human body is set as a reference working plane of the dynamic correction brace for scoliosis.

[0077] The six first pneumatic cylinders 22 are circumferentially spaced apart and distributed between the hip exoskeleton frame and the rib exoskeleton frame 23 , and the six second pneumatic cylinders 24 are circumferentially spaced apart and distributed between the armpit exoskeleton frame 25 and the rib exoskeleton frame 23 .

[0078] The installation positions and angles of the six first pneumatic cylinders 22 can be selected as needed.

[0079] The installation positions and angles of the six second pneumatic cylinders 24 can be selected as needed.

[0080] A two-layer six-degree-of-freedom dynamic correction brace for scoliosis is formed by six first pneumatic cylinders 22 and six second pneumatic cylinders 24.

[0081] While the patient is wearing it, the posture of the dynamic correction brace for scoliosis is actively changed by adjusting the displacement of each first pneumatic cylinder 22 and each second pneumatic cylinder 24 to track the patient's pitching, bending, lateral extension, sitting and other movements, so as to achieve effective correction of the patient in any posture for a long time. The driving method of using air valves to adjust the displacement of each first pneumatic cylinder 22 and each second pneumatic cylinder 24 effectively avoids the heating and endurance problems caused by high-frequency starting and long-term output of the linear motor. When an external air source is used, the weight of the dynamic correction brace for scoliosis is also greatly reduced.

[0082] In some optional embodiments, such as Figure 1 to Figure 2 As shown, the present invention provides a dynamic correction brace for scoliosis, and the dynamic correction brace for scoliosis also includes:

[0083] The first sensor group is arranged on the first pneumatic cylinder 22 and is used to monitor the telescopic end pressure, telescopic length and air pressure value of the first pneumatic cylinder 22 .

[0084] The second sensor group is arranged on the second pneumatic cylinder 24 and is used to monitor the telescopic end pressure, telescopic length and air pressure value of the second pneumatic cylinder 24 .

[0085] Specifically, the first sensor group includes two air pressure sensors, a potential sensor, and a pressure sensor. The two air pressure sensors are respectively arranged at two ends of the cylinder body of the first air pressure cylinder 22, and the air pressure sensors are used to monitor the air pressure value of the first air pressure cylinder 22.

[0086] The potential sensor is installed at the top of the telescopic end of the first pneumatic cylinder 22 , and the potential sensor is used to monitor the telescopic length of the first pneumatic cylinder 22 .

[0087] The pressure sensor is installed at the top of the telescopic end of the first pneumatic cylinder 22 , and the pressure sensor is used to monitor the pressure of the telescopic end of the first pneumatic cylinder 22 .

[0088] Specifically, the second sensor group includes two air pressure sensors, a potential sensor, and a pressure sensor. The two air pressure sensors are respectively arranged at two ends of the cylinder body of the second air pressure cylinder 24 , and the air pressure sensors are used to monitor the air pressure value of the second air pressure cylinder 24 .

[0089] The potential sensor is installed on the top of the telescopic end of the second pneumatic cylinder 24 , and the potential sensor is used to monitor the telescopic length of the second pneumatic cylinder 24 .

[0090] The pressure sensor is installed at the top of the telescopic end of the second pneumatic cylinder 24 , and the pressure sensor is used to monitor the pressure of the telescopic end of the second pneumatic cylinder 24 .

[0091] Each first pneumatic cylinder 22 is installed with a first sensor group, and each second pneumatic cylinder 24 is installed with a second sensor group.

[0092] Through the monitoring of the first sensor group and the second sensor group, the patient's pitching, bending, lateral extension, sitting and other movements are tracked to achieve effective correction of the patient in any posture for a long time. The patient's posture is tracked in real time while ensuring the correction effect. And according to the monitoring data, the displacement of each first pneumatic cylinder 22 and each second pneumatic cylinder 24 can be adjusted in real time to actively change the posture of the dynamic correction brace for scoliosis, so as to track the patient's pitching, bending, lateral extension, sitting and other movements, and achieve effective correction of the patient in any posture for a long time.

[0093] In some optional embodiments, such as Figure 1 to Figure 2As shown, the present invention provides a dynamic correction brace for scoliosis, the dynamic correction brace for scoliosis includes a rib exoskeleton frame 23, the rib exoskeleton frame 23 includes: a first connecting member 1, a second connecting member 2, a third connecting member 3, and a fourth connecting member 4 connected in sequence;

[0094] A first strap connection hole 8 is provided at the first end of the first connection member 1, and a second end of the first connection member 1 is hinged to a first end of the second connection member 2;

[0095] The second end of the second connecting member 2 is connected to the first end of the third connecting member 3 through a rib width adjustment bridge 7;

[0096] The second end of the third connecting member 3 is hinged to the first end of the fourth connecting member 4 , and the second end of the fourth connecting member 4 has a second strap connecting hole 9 .

[0097] Specifically, the first end of the first connecting member 1 is provided with a first strap connecting hole 8, the second end of the first connecting member 1 is hinged to the first end of the second connecting member 2, the second end of the second connecting member 2 is connected to the first end of the third connecting member 3 through the rib width adjustment bridge 7, the second end of the third connecting member 3 is hinged to the first end of the fourth connecting member 4, and the second end of the fourth connecting member 4 is provided with a second strap connecting hole 9.

[0098] Considering the convenience of putting on and taking off for the patient, the rib strap passes through the first strap connection hole 8 and the second strap connection hole 9, and the first end of the first connector 1 is connected to the second end of the fourth connector 4 through the rib strap. In this embodiment, the nylon braided elastic rib strap passes through the first strap connection hole 8 and the second strap connection hole 9 located on both sides of the front of the patient, and the rib exoskeleton frame 23 can always fit the human body by adjusting the length of the rib strap.

[0099] like Figure 1 to Figure 2 As shown, in some optional embodiments, there are multiple rib width adjustment bridges 7, and the length of each rib width adjustment bridge 7 is different.

[0100] The length of each rib width adjustment bridge 7 is different. Taking into account the body shape differences between patients and the errors in body shape measurement, the rib width adjustment bridge 7 is designed to achieve the reuse of the rib exoskeleton frame 23 in different body shapes. By replacing the rib width adjustment bridges 7 of different lengths, the adaptation range of the rib exoskeleton frame 23 can be expanded, which can effectively improve the efficiency of customized dynamic braces for patients.

[0101] In some optional embodiments, the second end of the first connecting member 1 is hinged to the first end of the second connecting member 2 through a first variable damping hinge 5, and the second end of the third connecting member 3 is hinged to the first end of the fourth connecting member 4 through a second variable damping hinge 6.

[0102] The rib exoskeleton frame 23 is divided into three sections by the first variable damping hinge 5 and the second variable damping hinge 6. When the first variable damping hinge 5 and the second variable damping hinge 6 are in a low damping state, it is easier for the patient to put on and take off the brace. After the patient has put on the brace, the first variable damping hinge 5 and the second variable damping hinge 6 in a high damping state can effectively improve the stability of the motion control of the dynamic correction brace for scoliosis.

[0103] like Figure 1 to Figure 2 As shown, in some optional embodiments, the first connecting member 1, the second connecting member 2, the third connecting member 3, and the fourth connecting member 4 are all provided with at least one outer mounting portion.

[0104] Furthermore, the outer mounting portion includes a rectangular groove and an outer mounting hole 14 disposed in the rectangular groove.

[0105] Furthermore, each of the first connecting member 1 , the second connecting member 2 , the third connecting member 3 , and the fourth connecting member 4 is installed with at least one driver mounting seat 15 .

[0106] Furthermore, a universal coupling 16 is installed on the top surface of the driver mounting seat 15 , and / or a universal coupling 16 is installed on the bottom surface of the driver mounting seat 15 .

[0107] Specifically, each driver mounting seat 15 is limited by a corresponding rectangular groove, and the outer mounting holes 14 in the corresponding rectangular groove are detachably mounted on the first connecting member 1, the second connecting member 2, the third connecting member 3, and the fourth connecting member 4. Those skilled in the art can select the installation position and quantity of each driver mounting seat 15 as needed.

[0108] The positions and numbers of the outer mounting parts on the first connecting member 1 , the second connecting member 2 , the third connecting member 3 , and the fourth connecting member 4 can also be selected according to needs.

[0109] A universal coupling 16 is installed on the top surface of the driver mounting seat 15, and / or a universal coupling 16 is installed on the bottom surface of the driver mounting seat 15. The universal coupling 16 can connect the first pneumatic cylinder 22 and the second pneumatic cylinder 24 to achieve parallel driving of the hip exoskeleton frame, the rib exoskeleton frame 23, and the underarm exoskeleton frame 25.

[0110] Due to the existence of the universal joint 16 , six-degree-of-freedom control is achieved among the hip exoskeleton frame, the rib exoskeleton frame 23 , and the armpit exoskeleton frame 25 .

[0111] Each actuator mounting seat 15 can be connected to two pairs of first pneumatic cylinders 22 and second pneumatic cylinders 24. The paired distribution of the first pneumatic cylinders 22 and the second pneumatic cylinders 24 can also reduce the modeling measurement error in the control of the dynamic correction brace for scoliosis.

[0112] like Figure 1 to Figure 2 As shown, in some optional embodiments, the rib exoskeleton frame 23 further includes:

[0113] The rib back pad 12 has one end connected to the inner side surface of the second end of the second connecting member 2 , and the other end connected to the inner side surface of the first end of the third connecting member 3 .

[0114] The rib exoskeleton frame 23 further includes:

[0115] A left rib pad 10, which is arranged on the inner side of the first connecting member 1;

[0116] The right rib pad 11 is arranged on the inner side of the fourth connecting member 4 .

[0117] Specifically, the rib back pad 12 is detachably connected to the second connecting member 2 and the third connecting member 3 through the inner mounting holes 13 on the second connecting member 2 and the third connecting member 3 .

[0118] The left rib pad 10 is connected to the first connecting member 1 through the inner mounting hole 13 on the inner side surface of the first connecting member 1 .

[0119] The right rib pad 11 is connected to the fourth connecting member 4 through the inner mounting hole 13 on the inner side surface of the fourth connecting member 4 .

[0120] There is a 2 cm gap between the rib exoskeleton frame 23 and the human body, and no force is directly applied to the human body. On the rib exoskeleton frame 23, only the rib back pad 12, the left rib pad 10, and the right rib pad 11 are in direct contact with the human body.

[0121] The rib back pad 12 is used to provide support for the back, ensuring that the dynamic correction brace for scoliosis is always in close contact with the human body.

[0122] The rib back pad 12 is made of nylon material by 3D printing, and the surface is wrapped with a skin-friendly silicone film. It is installed on the back of the rib exoskeleton frame 23 at the human spine to provide simple support.

[0123] The left rib pad 10 needs to be customized according to the patient's scoliosis symptoms under the guidance of the brace therapist, and can directly provide the patient with the correct correction force. When the first pneumatic cylinder 22 and the second pneumatic cylinder 24 are locked in the initial position, the left rib pad 10 can provide the patient with a correction force equivalent to that of a traditional brace.

[0124] The right rib pad 11 needs to be customized according to the patient's scoliosis symptoms under the guidance of the brace therapist, and can directly provide the patient with the correct correction force. When the first pneumatic cylinder 22 and the second pneumatic cylinder 24 are locked in the initial position, the right rib pad 11 can provide the patient with a correction force equivalent to that of a traditional brace.
