DETAILED DESCRIPTION

[0024] The following describes embodiments of the present invention in detail, with examples of these embodiments illustrated in the accompanying drawings. Throughout, identical or similar reference numerals denote identical or similar elements or elements having identical or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention, and are not to be construed as limiting the present invention. It should be noted that the terms "front," "back," "left," and "right" herein refer to specific positions of the torticollis brace of this embodiment when in actual use.

[0025] like Figure 1 and Figure 2As shown, the present invention provides a torticollis orthosis, comprising a base assembly 1, two support assemblies 2, two straps 3 and an orthosis 4. The base assembly 1 serves as the base of the torticollis orthosis and is worn on the patient's chest and / or shoulders to provide stable support. The two support assemblies 2 are relatively mounted on the base assembly 1, and both ends of the orthosis 4 are rotatably mounted on the corresponding end of the support assembly 2 away from the base assembly 1, so as to rotate in the vertical direction relative to the support assembly 2 to adjust the inclination angle of the orthosis 4. The two support assemblies 2 are each connected to a strap 3, and the ends of the two straps 3 away from the support assembly 2 can be buckled and connected to be fixed to the back of the head to ensure that the torticollis orthosis is stably worn; the orthosis 4 comprises a supporting portion 41, a connecting portion 42 and a rotating structure 43. The supporting portion 41 is used to support the patient's lower jaw, and the connecting portion 42 is in an arc shape bent forward, and both ends of the connecting portion 42 are toward the support assemblies 2 on both sides thereof. Extension, that is, extension to the left and right directions, and the two ends of the connection part 42 are respectively rotatably connected to the corresponding support components 2, so that the orthopedic component 4 as a whole can rotate around the support component 2 in the vertical direction, and the inclination angle of the support part 41 can be adjusted as needed to facilitate the placement of the patient's lower jaw or simulate the movement trajectory of the head raising or lowering the head to cooperate with the patient to adjust the corresponding rehabilitation training posture. The support part 41 is movably installed on the side of the connection part 42 away from the base component 1, and the rotating structure 43 is installed on the connection part 42, and the rotating structure 43 is connected to the support part 41 to drive the support part 41 to rotate relative to the connection part 42 along the extension direction of the connection part 42. Due to the provision of the rotating structure 43, the support part 41 can be rotated around the cervical spine of the human body to a suitable position, adapting to different stages of rehabilitation, and gradually rotating the patient's head to the correct position, not just directly restricting the patient's head to the correct position.

[0026] Based on the above structure, this embodiment can not only provide necessary support and protection for patients with torticollis, but also simulate rehabilitation movements in rehabilitation training (such as turning the head to the affected side, lowering or raising the head, etc.), helping children overcome movement restrictions caused by muscle contracture or postoperative adhesions, promote dynamic stretching and reduction of neck muscles, prevent postoperative adhesions, and solve the problem that existing orthoses only restrict bad postures by fixation.

[0027] Furthermore, the rotating structure 43 includes a first driving member (not shown in the figure), a driving gear 431, a driven part (not shown in the figure) and a plurality of connecting shafts 432. The driving gear 431 is installed in the connecting part 42. The plurality of driving gears 431 are meshed and connected in sequence to form a gear set. The plurality of driving gears 431 are arranged along the extension direction of the connecting part 42. The connecting part 42 serves to protect the driving gear 431 and provide an installation space for it. The first driving member is used to provide power input. One end of the first driving member passes through the connecting part 42 and is connected to a driving gear 431 to directly drive the driving gear 431 to rotate and drive other driving gears 431 to rotate. The driven part is installed on the side of the supporting part 41 facing the gear set. The driven part is in the shape of an arc coaxial with the arc of the connecting part 42, and the driven part is provided with a rack meshing with the outer edge of the gear set. The rack is arranged along the extension direction of the connecting part 42. The rack of the driven part receives the power transmitted from the gear set through meshing, drives it to rotate, and realizes the power transmission from the first driving member to the supporting part 41; in addition, the side of the supporting part 41 facing the gear set is provided with a slide groove whose extension trajectory is coaxial with the arc of the connecting part 42, and the connecting part 42 and the side facing the supporting part 41 are provided with multiple connecting shafts 432, and the multiple connecting shafts 432 are arranged at intervals along the extension direction of the connecting part 42, and the end of the connecting shaft 432 away from the connecting part 42 is slidably installed in the slide groove, and the connecting shaft 432 cooperates with the slide groove to make the supporting part 41 more stable when rotating relative to the connecting part 42, and can keep the supporting part 41 rotating on one plane without interfering with the driving gear 431.

[0028] It can be understood that the supporting portion 41 of this embodiment is slidably connected to the connecting portion 42 via a connecting shaft 432, and the connecting shaft 432 includes a sliding end and a rod portion, one end of the rod portion is connected to the connecting portion 42, and the other end of the rod portion is connected to the sliding end, and the size of the sliding end is larger than the size of the rod portion, that is, the connecting shaft 432 is T-shaped. The chute includes a first chute and a second chute connected to the first chute, and the size of the first chute is smaller than the size of the second chute, so that the chute is T-shaped and compatible with the connecting shaft 432. The sliding end is slidably arranged in the second chute, and the size of the first chute is smaller than the size of the sliding end to prevent the connecting shaft 432 from detaching from the chute. The first driving member of this embodiment can be a knob or a motor. Preferably, the first driving member can be a motor.

[0029] Based on the above structure, this embodiment transmits the driving power of the first drive member to the support portion 41 through the meshing of the drive gear 431 and the driven portion, driving the support portion 41 to rotate, ensuring the controllability of the direction and angle of movement of the support portion 41. By driving the active or passive movement of the patient's head in this manner, the purpose of driving the patient's head to rotate laterally is achieved. When the first drive member stops driving, the self-locking nature of the gear meshing between the drive gear 431 and the rack of the driven portion prevents the support portion 41 from sliding due to gravity, ensuring the safety of the child. In addition, the gear transmission structure between the drive gear 431 and the rack of the driven portion occupies a small space and is suitable for installation within the connecting portion 42 of the torticollis orthosis, avoiding the complexity of the external structure and improving wearing comfort. It can be understood that if the gear ratio between the drive gear 431 and the rack of the driven portion is designed as a reduction ratio (e.g., the drive gear 431 has fewer teeth than the driven portion), the speed of the gear transmission structure can be reduced and the output torque can be increased, meeting the power requirements of the support portion 41.

[0030] It should be noted that the first driving member of this embodiment is a knob, which drives the rotation of the driving gear 431 by human force, and then drives the rotation of the supporting part 41. Preferably, a scale is set on the side of the connecting part 42 to determine the rotation angle of the supporting part 41. The rotation angle can be 0°~180° to adapt to the training needs of different rehabilitation stages. The rotation angle can also be adjusted according to actual needs.

[0031] In some embodiments, the first drive member is a motor, such as a micromotor or a stepper motor, so that the speed of the first drive member is adjustable. For example, a stepper motor can be controlled by a pulse signal to achieve progressive rehabilitation training from low speed to high speed. In addition, the rotation angle of the support portion 41 can be controlled by controlling the number of rotations of the first drive member. The rotation angle can be between 0° and 180° to meet the training needs of different rehabilitation stages.

[0032] In some embodiments, in order to cooperate with the micro motor, a corresponding angle sensor can be set as needed to monitor the rotation angle of the supporting part 41, so as to determine the deflection angle of the patient's head. When the posture of the patient's head is incorrect, the supporting part 41 can be adjusted to the angle accordingly to correct the posture of the patient's head. The structure of the first driving member is not particularly limited here.

[0033] Furthermore, the supporting portion 41 includes a supporting plate 411 and two cheek support members 412. The supporting plate 411 serves as an installation base, and a driven portion is provided on the side facing the gear group. The other end of the connecting shaft 432 is slidably connected to the slide groove of the supporting plate 411 to achieve connection with the connecting portion 42. The cheek support member 412 has an arc, and the two cheek support members 412 are relatively arranged on the supporting plate 411 to form a cheek support space adapted to the cheek, so that when the patient places his lower jaw on the supporting plate 411, the cheek support member 412 can fit or fix the patient's cheek, preventing the patient from turning his head significantly while allowing the patient's head to move with the rotation of the supporting plate 411.

[0034] It should be noted that the cheek support 412 of this embodiment can be made of a material with a certain degree of deformation ability, so as to adapt to the cheek sizes of different patients through elastic deformation.

[0035] Furthermore, the cheek support piece 412 has a plurality of flexible protrusions (not shown in the figure) on one side facing the cheek support space and / or the supporting portion 41 located in the cheek support space. The flexible protrusions can increase the friction between the torticollis brace and the mandible and / or cheek skin, thereby preventing the patient's head from sliding or shifting during the use of the torticollis brace. Similarly, the flexible protrusions can also provide additional cushioning effects and disperse pressure, thereby reducing discomfort or pressure point pain that may be caused by excessive local pressure concentration due to long-term wearing of the torticollis brace, helping to maintain good blood circulation and avoid blood stasis caused by long-term wearing. For children, their skin is more sensitive, so providing flexible protrusions can help improve comfort when wearing.

[0036] Furthermore, the flexible nature of the multiple flexible protrusions facilitates a certain degree of adaptation and adjustment based on the specific contours of the patient's jaw, thereby enabling the torticollis brace to fit more tightly and naturally against the patient's jaw and / or cheek. It is understood that the protrusions are spaced apart on the support portion 41, and the flexible protrusions may be dots, stripes, or other shaped protrusions. The structure of the flexible protrusions is not particularly limited herein.

[0037] In some embodiments, a small airbag can be placed within the support portion 41 in place of the flexible protrusions. The patient can adjust its hardness and shape by inflating it to suit their personal needs. Alternatively, a memory foam material can be used as the contact surface of the support portion 41, adapting its shape in a pressure-adaptive manner to provide the patient with an excellent fit and comfort. Furthermore, a combination of multiple materials (such as a soft silicone layer plus a breathable fabric) can be used to ensure sufficient softness and provide necessary support, while also increasing breathability and reducing discomfort caused by sweating.

[0038] Furthermore, it also includes a rotating structure 5, which includes a second driving member 51 and a rotating shaft (not shown in the figure). One end of the rotating shaft passes through the supporting assembly 2 and is fixedly connected to the connecting part 42, so that when the rotating shaft rotates, the connecting part 42 will also rotate accordingly. The second driving member 51 is installed on the supporting assembly 2, and the second driving member 51 is connected to the other end of the rotating shaft, which is used to provide power to drive the rotating shaft to rotate, so as to drive the connecting part 42 to rotate in the vertical direction.

[0039] In this embodiment, the second driving member 51 drives the rotation of the rotating shaft, so that the connecting portion 42 can drive the supporting portion 41 to rotate as needed to adjust the tilt angle, so that the patient's lower jaw can be placed or simulate the movement trajectory of the head raising or lowering, driving the patient's head to adjust the corresponding rehabilitation training posture. It should be noted that the second driving member 51 of this embodiment is a knob, which adjusts the angle of the connecting portion 42 by manually applying force to drive the rotation of the rotating shaft, thereby driving the supporting portion 41 to rotate to achieve the adjustment of its tilt angle. In addition, a limiter is provided between the rotating shaft and the support assembly 2 to limit the rotation angle between the two.

[0040] In some embodiments, the second driving member 51 can also be a micro motor or a stepping motor, so that the rotation of the connecting part 42 can be completed automatically, reducing dependence on the patient's own ability, so as to meet the rehabilitation treatment needs of children whose self-control ability and body coordination are not yet fully developed. The structure of the second driving member 51 is not specifically limited here.

[0041] In addition to the aforementioned shaft transmission method, a small motor can also be used as the driving source, with the motor's rotational force transmitted to the shaft via a gear set, thereby driving the connection portion 42 to rotate, thereby more accurately controlling the rotation speed and angle. In addition, corresponding angle sensors can be provided as needed to monitor the patient's head-raising or head-lowering angle. If the patient's head posture is incorrect, the tilt angle of the support portion 41 can be adjusted accordingly to correct the patient's head posture.

[0042] Furthermore, the connecting portion 42 includes a mounting plate 421 and two connecting members 422 integrally formed with the mounting plate 421. One end of the connecting member 422 is rotatably connected to the corresponding support assembly 2, and the other end of the connecting member 422 is connected to the mounting plate 421. This allows the entire orthotic assembly 4 to rotate freely within a certain range, allowing the patient to adjust their head-up or head-down posture. Furthermore, the mounting plate 421 and connecting members 422 are integrally formed in an arc shape. The arc shape of the connecting members 422 adapts to the anatomy of the human jaw and neck, improving wearer comfort. The above structure makes the mounting plate 421 located in the middle, providing an installation basis for the rotating structure 43, the driving gear 431 and the driven part are installed in the mounting plate 421, the supporting part 41 is rotatably installed on the mounting plate 421, and the first driving member is installed on the side of the mounting plate 421 away from the supporting part 41, and passes through the mounting plate 421 to be connected with the driving gear 431, one end of the connecting shaft 432 is fixed on the mounting plate 421, and the other end is slidably connected to the slide groove of the supporting part 41, so that the supporting part 41 can rotate relative to the mounting plate 421, and the connecting member 422 and the mounting plate 421 are arc-shaped as a whole. The supporting part 41 can slide relative to the mounting plate 421 to the top of the connecting member 422, thereby assisting the patient to complete a specific rehabilitation exercise posture to guide the patient's head to perform corresponding side head movements and improve the controllability of rehabilitation training.

[0043] As can be understood, the mounting plate 421 and connector 422 of this embodiment are made of a new lightweight and high-strength material (e.g., carbon fiber) to reduce the overall weight of the torticollis orthosis, improving patient wearing comfort while also ensuring sufficient strength and durability of the mounting plate 421 and connector 422. Furthermore, multiple different fixing points can be provided on the connector 422, allowing the connection position of the connector 422 to the support assembly 2 to be adjusted as needed, thereby adapting to a wider range of patient needs and usage scenarios.

[0044] Furthermore, the support assembly 2 includes a main seat 21, a sliding member 22 and a third driving member 23. The main seat 21 is installed on the base assembly 1 to provide a stable support base. The main seat 21 has a sliding cavity with an open top. The sliding member 22 is arranged above the main seat 21, and one end thereof is slidably installed in the sliding cavity. The sliding cavity provides a path for the movement of the sliding member 22 and limits its sliding direction. The third driving member 23 is connected to the sliding member 22 as a power source or driving device to drive the sliding member 22 to slide in the sliding cavity, so as to realize the adjustment of the overall height of the support assembly 2. The other end of the sliding member 22 One end is rotatably connected to the connecting portion 42, allowing the orthotic assembly 4 to be adjusted in height to accommodate different patient head shapes and rehabilitation needs. For example, the two support assemblies 2 may be arranged one higher and one lower to adapt the orthotic assembly 4 to the patient's degree of torticollis and to accommodate different courses of rehabilitation treatment. Furthermore, since the relative distance between the sliders 22 of the two support assemblies 2 changes when the sliders 22 of the two support assemblies 2 are raised or lowered, in this embodiment, the connecting portion 42 may be made of a material with a certain degree of deformability to elastically adapt to the change in the distance between the sliders 22 of the two support assemblies 2. Preferably, a guide groove extending in the height direction may be provided on the main base 21, and the third driving member 23 may be slidably disposed within the guide groove. One end of the third driving member 23 is connected to the sliding member 22 via a connecting rod. As the third driving member 23 slides within the guide groove, multiple height adjustment positions may be provided within the guide groove, such as a plurality of elastic or retractable protrusions, thereby enabling multi-level height adjustment of the slider 22.

[0045] This embodiment provides a flexible and height-adjustable support structure, enabling the support portion 41 of the torticollis orthosis to be adjusted in height according to the specific circumstances of each patient, thereby adapting to the mandibular placement of different patients, thereby improving treatment effectiveness and patient comfort. It should be noted that in some embodiments, a locking member may also be provided, which is inserted into the main base 21 from a side or through the adjustment slot and tightened below the third drive member to secure the slide rod.

[0046] The main seat 21 and the sliding part 22 of this embodiment can be made of lightweight but high-strength materials (such as aluminum alloy or carbon fiber), which can not only reduce the overall weight of the torticollis orthosis, but also ensure the firmness and durability of the main seat 21 and the sliding part 22, thereby improving the patient's wearing experience.

[0047] In some embodiments, the third drive member 23 can also be a micromotor or a stepper motor, allowing the sliding of the slider 22 to be completed automatically, reducing reliance on the patient's own ability. In addition, a height sensor can be provided as needed to monitor the position of the slider 22 in real time and adjust it according to the patient's specific condition, further optimizing the rehabilitation training effect. In this case, a button is provided on the outside of the main base 21, and the third drive member 23 is provided with a power supply and a control panel within the main base 21 and connected to the third drive member 23 to activate the third drive member 23 to drive the slider 22 to slide. The structure of the third drive member 23 is not specifically limited herein.

[0048] Furthermore, a strap 3 is provided with a buckling portion (not shown in the figure) at one end away from the support component 2, and the buckling portion includes at least one fastener with an elastic arm, and the end of the fastener forms a hook protruding outward; the other strap 3 is provided with a buckling structure (not shown in the figure) cooperating with the buckling portion, and the buckling structure includes a positioning groove adapted to the fastener, and a card slot is provided on the side wall of the positioning groove, and the card slot has a card surface matching the shape of the hook.

[0049] The elastic arms of this embodiment provide the fastener with a degree of flexibility, allowing it to deform when appropriate pressure is applied, thereby facilitating its connection and disconnection with the fastening structure on the other strap 3. When the fastener is inserted into the positioning slot, the hook automatically engages with the engaging surface within the slot, providing a secure connection and ensuring that the strap 3 is securely fixed to the back of the patient's head, preventing the torticollis brace from slipping or falling off during use. Furthermore, the provision of the hook and slot allows the patient to quickly and easily install and remove the strap 3, enhancing ease of use.

[0050] In some embodiments, in addition to the mechanical hook and slot structure, a magnetic connection method can also be used. For example, a magnet is installed on one strap 3, and a corresponding metal sheet or other magnet is installed on the other strap 3, and the magnetic force is used to achieve quick connection and disconnection between the two. In addition, a pin structure can be used instead of the hook and slot structure, in which one strap 3 is equipped with a pin, and the other strap 3 is equipped with a corresponding socket. After the pin is inserted into the socket, the position can be maintained by an internal locking mechanism to provide a stable connection. The locking structure can be a method of setting a pin to fix the pin from the side, and the locking structure is not particularly limited here. It can be understood that Velcro can also be used as a connection method, with one side of one strap 3 covered with a hook surface, and the corresponding position of the other strap 3 covered with a velvet surface. A tight connection can be achieved by simply pressing to adapt to situations where frequent adjustments are required.

[0051] Furthermore, it also includes a neck and back pad 6, which can provide additional cushioning and support for the patient's neck and back, especially when wearing the torticollis brace for a long time, helping to reduce the pressure on the neck and back and improve the patient's wearing comfort. In this embodiment, an end of a strap 3 away from the support component 2 (i.e., an end of the strap 3 with a buckle structure) is connected to the back of the neck and back pad 6. The buckle structure is installed on the back of the neck and back pad 6 so that it can be buckled with another strap 3 on the back of the neck and back pad 6. The combination of the strap 3 and the neck and back pad 6 can better disperse the force applied by the torticollis brace on the head and neck, so that the entire torticollis brace is more firmly fixed to the patient, reducing the risk of displacement due to movement or external forces.

[0052] It is understandable that in some embodiments, an inflatable neck and back pad 6 structure can also be used to allow the patient to adjust the amount of air in the airbag according to their comfort needs. This not only improves the adaptability of the neck and back pad 6 for patients in different situations, but also can dynamically adjust the support strength of the neck and back pad 6 to a certain extent. In addition, memory foam can also be used as the material of the neck and back pad 6. This material can adaptively adjust its shape according to the patient's body shape and posture, providing better fit and support. In actual application, a detachable neck and back pad 6 can be used to replace different types of neck and back pads 6 according to the needs of different seasons or treatment stages (such as a breathable type in summer and a warm type in winter). It is also convenient for cleaning and maintenance. That is, the connection between the neck and back pad 6 and the buckling structure is a detachable connection method, such as buckling, bonding, etc., and its connection method is not particularly limited here.

[0053] like Figure 3 As shown, the base assembly 1 includes a base 11 and a cushion 12. Base 11 serves as the foundational structure of the entire torticollis brace, providing support. One side of the base 11 is connected to the support assembly 2. Base 11 has a collar opening 13 extending around the neck, allowing the brace to wrap around the patient's neck, providing stable support while ensuring comfort and safety. Cushion 12 is mounted on the side of the base 11 facing away from the support assembly 2 to enhance wearing comfort and reduce friction or discomfort on the patient's shoulders or chest that may be caused by prolonged wear of the brace.

[0054] To further enhance comfort, the cushioning pad 12 can be made of memory foam or gel filling material, which can better adapt to the contours of the patient's shoulders or chest, providing a more comfortable wearing experience. The base 11 of this embodiment can be made of a lightweight but high-strength material (such as lightweight plastic or carbon fiber), which can reduce the weight of the entire torticollis orthosis while ensuring the sturdiness and durability of the base 11, improving the patient's wearing experience.

[0055] Furthermore, the base 11 includes a supporting portion 111 and two ring necks 112 integrally formed with the supporting portion 111. The supporting portion 111 is used to support the chest to provide a stable support point, which helps to maintain the overall stability of the torticollis orthosis and helps distribute the force applied to the patient; the two ends of the supporting portion 111 are respectively connected to a ring neck 112 to form a ring neck opening 13. The ring neck 112 of this embodiment is based on ergonomic design and is arc-shaped. The convex surface of the ring neck 112 is connected to the support component 2. The ring neck 112 is The concave surface is used to be placed on the shoulder to ensure the comfort and stability of the patient when wearing it, so that the torticollis orthosis can fit the patient's shoulder, which not only ensures the support of the shoulder to the ring neck 112, but also does not cause discomfort to the patient; and in order to improve the comfort of the patient wearing it, the base component 1 can be formed by 3D printing. By first obtaining a 3D model of the patient's shoulder and neck and shoulder area, and then forming the base component 1 through 3D printing, the structure of the base component 1 can be personalized and customized, thereby effectively improving the comfort of the patient wearing the torticollis orthosis in this embodiment during the treatment process.

[0056] It should be noted that in some embodiments, the torticollis orthosis includes a built-in control panel and power supply, which are connected to the electrical components to control the electrical components. Furthermore, the sensor feedback can be linked to an external platform via a Bluetooth module or other means. This linkage method can be conventional Bluetooth linkage and is not particularly limited here.

[0057] The specific working process is as follows:

[0058] When in use, the supporting part 111 can be supported on the chest and the neck ring 112 can be placed on the shoulder. The second driving member 51 is used to control the rotation of the connecting part 42 so that the supporting part 41 and the supporting assembly 2 form an angle, which is adapted to the normal raised position of the mandible. At this time, the supporting part 41 tends to a horizontal position. With the support of the supporting part 41, the bottom end of the mandible can be kept horizontal, which plays a corrective role. If rehabilitation exercises are required, the supporting part 41 is driven to rotate by the second driving member 51 to raise the height of the mandible and assist the patient to raise his head. The first driving member, the driving gear 431 and the rack of the driven part cooperate to drive the supporting part 41 to rotate, thereby assisting the patient to turn his head, thereby assisting the patient to perform standard rehabilitation exercises and meet the corresponding rehabilitation training posture.

[0059] In summary, an embodiment of the present invention provides a torticollis orthosis, whose orthotic component 4 can rotate in the vertical direction around the support component 2, and the inclination angle of the supporting part 41 can be adjusted as needed to facilitate the placement of the patient's lower jaw or simulate the movement trajectory of raising or lowering the head to cooperate with the patient to adjust the corresponding rehabilitation training posture. The rotating structure 43 is connected to the supporting part 41 to drive the supporting part 41 to rotate relative to the connecting part 42 in its extension direction (i.e., the left and right direction), thereby driving the active or passive movement of the patient's head, so as to achieve the purpose of driving the patient's head to turn sideways. The present invention helps children overcome movement restrictions caused by muscle contracture or postoperative adhesion by simulating rehabilitation movements in rehabilitation training (such as turning the head to the affected side, lowering the head or raising the head, etc.), promotes dynamic stretching and reduction of the neck muscles, prevents postoperative adhesion, and solves the problem that existing orthoses only restrict bad postures by fixation.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
