Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically relates to a head, neck and chest orthosis. Background Technology

[0002] The head-chest-neck orthosis is used for patients with cervical spine injuries and high thoracic spine injuries. Its function is to restrict cervical spine movement and reduce the weight exerted on the cervical spine by the head. It also restricts forward and backward extension, flexion and extension, lateral flexion, and left and right rotation, while providing upward support. It provides protection for movement during postoperative fixation and rehabilitation of cervical spine injuries (excluding the atlantoaxial joint). It is commonly used for fixation and conservative treatment of cervical spondylosis and stable cervical fractures, providing more stable fixation of the cervical spine and restricting movement in all planes of the cervical spine to reduce the burden on the cervical spine. Indications: Suitable for fixation after reduction of cervical and upper thoracic spine fractures, cervical dislocations and subluxations; preoperative and postoperative fixation of the cervical spine; conservative treatment of mild cervical spondylosis, etc. It is a commonly used orthosis in spinal surgery and orthopedics.

[0003] The most widely used traditional head, neck, and chest orthoses consist of a pair of anterior and posterior chest films, an adjustable chin rest, an adjustable occipital rest, and an inner lining. In order to better adapt to the patient's neck height, adjustable head, neck, and chest orthoses have been developed in the current technology, in which the installation height of the chin rest and / or occipital rest on the corresponding chest film is adjustable.

[0004] However, the chin support and / or back pillow of the existing adjustable head, neck and chest orthoses can only be adjusted in the height direction, and cannot adjust the tilt angle.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0050] Example:

[0051] The head, neck, and chest orthosis provided in this embodiment includes a chest X-ray 100 and a backplate, a support plate 200, a mounting platform 500, an adjustment mechanism, and a support component 600, wherein:

[0052] A strap 110 is provided between the chest piece 100 and the back plate for easy wearing. The support plate 200 is detachably mounted on the chest piece 100 or the back plate. Specifically, the support plate 200 can be mounted on the chest piece 100 or the back plate using existing methods, such as using multiple connecting studs or ear plates, to ensure that the support plate 200 is securely connected to the chest piece 100 or the back plate. In this embodiment, the support plate 200 is a rigid plate.

[0053] The mounting platform 500 is movably mounted on the support plate 200 via an adjustment mechanism, which allows adjustment of the position and / or tilt angle of the mounting platform 500. A support member 600, which is a chin rest or a headrest, floats on the mounting platform 500.

[0054] If the support 600 is a chin support, then the chin support is mounted on the chest X-ray 100 via the mounting platform 500, the adjustment mechanism, and the support plate 200. That is, the position and / or tilt angle of the chin support can be adjusted by the aforementioned adjustment mechanism.

[0055] If the support 600 is a rear headrest, then the rear headrest is mounted on the back panel via the mounting platform 500, the adjustment mechanism, and the support plate 200. That is, the position and / or tilt angle of the rear headrest can be adjusted by the adjustment mechanism.

[0056] Of course, the chin support can also be mounted on the chest X-ray 100 simultaneously via a mounting platform 500, an adjustment mechanism and a support plate 200, and the occiput support can be mounted on the back panel via another mounting platform 500, another adjustment mechanism and another support plate 200, so that the position and / or tilt angle of the occiput support and the chin support can be adjusted.

[0057] The aforementioned chin support is used to support the patient's chin, while the occipital support is used to support the back of the patient's head. In this embodiment, the chin support and occipital support are made of flexible materials, similar to existing technologies, to enhance comfort. This embodiment will be described using the example of the chin support being mounted on the chest X-ray 100 via a mounting platform 500, an adjustment mechanism, and a support plate 200.

[0058] The head, neck, and chest orthosis with the above-described structure allows for adjustment of the position of the mounting platform 500 via the aforementioned adjustment mechanism, thereby adjusting the position of the support 600. Furthermore, the adjustment mechanism also allows for adjustment of the tilt angle of the mounting platform 500, which in turn adjusts the tilt angle of the support 600. Thus, the head, neck, and chest orthosis provided by this invention not only allows for convenient adjustment of the position of the chin support and / or occipital support, but also facilitates adjustment of the tilt angle of the chin support and / or occipital support. This makes the orthosis suitable for patients with different head shapes or facial contours, offering better adaptability, higher versatility, and greater practicality. Moreover, the support angle for the patient's head can be adjusted as needed to better facilitate patient recovery.

[0059] Optionally, the adjustment mechanism in this embodiment includes a first adjustment rod 300 and a second adjustment rod 400, wherein:

[0060] The first adjusting rod 300 extends along a first direction and is movably connected to the support plate 200 along the first direction, wherein the first direction is... Figure 2 and Figure 3 In the Z-direction, the first direction is actually vertical, referring to the up-down direction when the patient is standing upright; vertical deviation when the patient is standing is ignored here. Adjusting the first adjusting rod 300 means controlling the first adjusting rod 300 to slide vertically, thereby changing the vertical distance between the top of the first adjusting rod 300 and the support plate 200.

[0061] The second adjusting rod 400 extends along the first direction and is movably connected to the first adjusting rod 300 along the first direction. Adjusting the second adjusting rod 400 means controlling the second adjusting rod 400 to slide vertically, thereby changing the vertical distance between the top of the second adjusting rod 400 and the support plate 200.

[0062] The mounting platform 500 is equipped with a first hinge portion, a second hinge portion, and a third hinge portion. The second hinge portion and the third hinge portion are arranged parallel to each other and spaced apart along a second direction, wherein the second direction is... Figure 2 In the X-direction, the second direction is actually the left-right direction when the patient is upright. That is, the second and third hinges are parallel and spaced apart in the left-right direction. Furthermore, both the second and third hinges are spaced apart from the first hinge in the third direction. At this point, the first, second, and third hinges are located at the three vertices of a triangle. Ideally, the distances from the first hinge to the second and third hinges are the same, making the triangle an isosceles triangle. In this embodiment, the third direction is... Figure 3 In the Y direction, the third direction is actually the front-back direction when the patient is upright, that is, the first hinge and the second / third hinge are offset in the front-back direction. The first hinge is hinged to the top of the first adjusting rod 300, and the second and third hinges are both hinged to the top of the second adjusting rod 400.

[0063] It is easy to understand that the first direction, the second direction, and the third direction in this embodiment are three mutually perpendicular directions in three-dimensional space. The first hinge, the second hinge, and the third hinge are all ball hinge structures.

[0064] At this time, the three hinged parts are respectively hinged to the first adjusting rod 300 and the second adjusting rod 400, thereby providing three-point support for the mounting platform 500. This allows the mounting platform 500 to be stably supported even without adjusting the first adjusting rod 300 and the second adjusting rod 400, so that the support 600 on the mounting platform 500 is stable.

[0065] The adjustment mechanism described above can adjust not only the position of the mounting platform 500 and the support 600 in the first direction, but also the tilt angle of the mounting platform 500 and the support 600 in the second and third directions. Specifically, when the first adjustment rod 300 is adjusted, it causes the first adjustment rod 300 to rise and fall in the first direction. Since the second adjustment rod 400 is connected to the first adjustment rod 300, in this case, the mounting platform 500 and the support 600 on it will rise and fall, that is, adjust the vertical position of the mounting platform 500 and the support 600 on it. When the second adjusting rod 400 is adjusted, the tilt angle of the mounting platform 500 in the second or third direction can be adjusted. Since the second adjusting rod 400 is hinged to both the second and third hinge portions, and the first adjusting rod 300 is hinged to the first hinge portion, and the first and second / third hinge portions are spaced apart in the third direction (front-back direction), driving the second adjusting rod 400 to slide in the first direction allows the mounting platform 500 and its support member 600 to rotate around the first hinge portion in the third direction, thereby adjusting the tilt angle of the mounting platform 500 and its support member 600 in the third direction. Of course, in this embodiment, the second adjusting rod 400 can be a single rod, which is hinged to both the second and third hinge portions. In this case, the tilt angle of the mounting platform 500 and its support member 600 can only be adjusted in the third direction.

[0066] In this embodiment, there are two second adjustment rods 400, arranged side by side in the second direction. The top of one second adjustment rod 400 is hinged to the second hinge, and the top of the other second adjustment rod 400 is hinged to the third hinge. When both second adjustment rods 400 are adjusted synchronously and in the same direction, the tilt angle of the mounting platform 500 in the third direction is adjusted. When both second adjustment rods 400 are adjusted synchronously and in the same direction, the tilt angle of the mounting platform 500 in the second direction is adjusted. Thus, when the patient needs to adjust the tilt angle of the chin rest or occipital support in the anterior-posterior direction, both second adjustment rods 400 are adjusted synchronously and in the same direction, allowing them to rise and fall synchronously and in the same direction. When the patient needs to adjust the tilt angle of the chin rest or occipital support in the lateral direction, both second adjustment rods 400 are adjusted synchronously and in opposite directions, allowing them to rise and fall synchronously and in opposite directions.

[0067] Optionally, in this embodiment, the first adjusting rod 300 is as follows: Figures 1-4As shown, it includes a plate 310 and two support rods 330 connected to the plate 310. The support rods 330 extend along a first direction, and their top ends are connected to the bottom ends of the plate 310. Specifically, the support rods 330 and the plate 310 are integrally formed. A protrusion 320 is provided at the top end of the plate 310, which is hinged to a first hinge portion on the mounting platform 500. The two support rods 330 are spaced apart in a second direction, and both support rods 330 are slidably connected to the support plate 200 along the first direction. Thus, when the support rods 330 slide on the support plate 200, the first adjusting rod 300 can be adjusted.

[0068] Optionally, to slidably connect the support rod 330 to the support plate 200, in this embodiment, a groove 210 is provided on the support plate 200 along a first direction. A slider 340 is provided at the end of the support rod 330 away from the plate 310, and the slider 340 is slidably mounted in the groove 210. A plurality of first connecting holes 220 are provided at the bottom of the groove 210, and the plurality of first connecting holes 220 are evenly distributed in the first direction. A first positioning hole 341 is provided in the slider 340, and a first positioning connector 700 is connected to the first positioning hole 341 and one of the first connecting holes 220. Specifically, the first positioning connector 700 is a locking pin or a bolt. When the first positioning connector 700 is connected to different first connecting holes 220, the height of the support rod 330 is different, thereby adjusting the vertical distance between the top of the first adjusting rod 300 and the support plate 200. Of course, the first adjusting rod 300 can also be a telescopic rod. Alternatively, the support rod 330 can also be mounted on the support plate 200 using a linear motor.

[0069] Optionally, in this embodiment, the second adjusting rod 400 is as follows: Figures 1-3 As shown, the second adjusting rod 400 includes a connecting rod 410 and a fine-tuning rod 420. The connecting rod 410 extends along a first direction and is slidably connected to the first adjusting rod 300 along the first direction. The fine-tuning rod 420 extends along the first direction and is slidably connected to the connecting rod 410 along the first direction. The top end of the fine-tuning rod 420 is hinged to a second hinge portion / third hinge portion. When the connecting rod 410 slides on the first adjusting rod 300 and / or when the fine-tuning rod 420 slides on the connecting rod 410, the second adjusting rod 400 is adjusted. It is easy to understand that the second adjusting rod 400, composed of the connecting rod 410 and the fine-tuning rod 420, is actually a telescopic rod. Of course, the second adjusting rod 400 can also be a non-telescopic rod. However, the preferred method in this embodiment is to set the second adjusting rod 400 as a telescopic rod composed of the connecting rod 410 and the fine-tuning rod 420.

[0070] In one optional embodiment, the connecting rod 410 is connected to the plate 310 of the first adjusting rod 300. In the preferred embodiment, the connecting rod 410 is connected to the support rod 330 of the first adjusting rod 300, and the connecting rods 410 of the two second adjusting rods 400 are respectively connected to the two support rods 330 of the first adjusting rod 300. Specifically, the lower part of the connecting rod 410 is slidably connected to the support rod 330 along a first direction, and the lower part of the fine-tuning rod 420 is slidably connected to the upper part of the connecting rod 410. The travel distance of the fine-tuning rod 420 on the connecting rod 410 is less than the travel distance of the connecting rod 410 on the support rod 330.

[0071] When the first adjusting rod 300 is fixed on the support plate 200 and the connecting rod 410 is fixed on the first adjusting rod 300, the tilt angle of the mounting platform 500 can be adjusted by adjusting the position of the fine-tuning rod 420. Specifically, when the two fine-tuning rods 420 are adjusted synchronously and in the same direction, the tilt angle of the mounting platform 500 and the support member 600 in the third direction is changed. When the two fine-tuning rods 420 are adjusted synchronously and in opposite directions, the tilt angle of the mounting platform 500 and the support member 600 in the second direction is changed. In addition, it is easy to understand that the sliding of the connecting rod 410 on the first adjusting rod 300 is actually the sliding of the second adjusting rod 400 on the first adjusting rod 300. That is, the adjustment effect of the sliding of the connecting rod 410 on the first adjusting rod 300 on the mounting platform 500 is actually the adjustment effect of the sliding of the second adjusting rod 400 on the first adjusting rod 300 on the mounting platform 500. Of course, the adjustment effect of the fine-tuning rod 420 on the tilt angle of the mounting platform 500 is less than that of the connecting rod 410 on the tilt angle of the mounting platform 500.

[0072] It is worth noting that the movement of the two fine-adjustment rods 420 and the connecting rod 410 can all adjust the tilt angle of the mounting platform 500. In actual use, the front-to-back tilt angle of the mounting platform 500 is adjusted by simultaneously and in the same direction by adjusting the two fine-adjustment rods 420 and / or the two connecting rods 410, while the left-to-right tilt angle of the mounting platform 500 is adjusted by adjusting one of the fine-adjustment rods 420. When wearing the device, after adjusting the first adjusting rod 300 to the correct position, the second adjusting rod 400 can be adjusted, and finally the fine-adjustment rod 420 can be adjusted to meet the different usage needs of patients for the chin support and / or occipital support in terms of height, front-to-back tilt angle, and left-to-right tilt angle.

[0073] Optionally, in this embodiment, the connecting rod 410 is as follows: Figure 3 and Figure 5As shown, it includes a first straight rod segment 411, a second straight rod segment 412, and a curved rod segment 413. The first straight rod segment 411 is slidably connected to the support rod 330 of the first adjusting rod 300 along a first direction. The fine-tuning rod 420 is slidably connected to the second straight rod segment 412 along the first direction. The curved rod segment 413 is fixed between the first straight rod segment 411 and the second straight rod segment 412 so that the first straight rod segment 411 and the second straight rod segment 412 are offset in a third direction.

[0074] In this embodiment, the connecting rod 410 of the second adjusting rod 400 and the support rod 330 of the first adjusting rod 300 are slidably connected along a first direction. Specifically, a plurality of second connecting holes 331 are provided on the support rod 330 of the first adjusting rod 300, and the plurality of second connecting holes 331 are evenly distributed in the first direction. A second positioning hole 4111 is provided on the first straight rod section 411 of the connecting rod 410. The second positioning connector 800 passes through the second positioning hole 4111 and connects to one of the second connecting holes 331. Specifically, the second positioning connector 800 is a locking pin or a bolt, and when the second positioning connector 800 is a bolt, the stud section of the bolt passes through the second positioning hole 4111 and the second connecting hole 331 and is screwed to a nut. Thus, when the second positioning connector 800 is connected to different second connecting holes 331, the connection position of the connecting rod 410 on the support rod 330 (i.e. the first adjusting rod 300) is different, resulting in different heights of the second adjusting rod 400, thereby adjusting the height position of the second adjusting rod 400 relative to the first adjusting rod 300.

[0075] Optionally, in order to allow the fine-tuning rod 420 to be slidably connected to the second straight rod section 412 of the connecting rod 410, in this embodiment, a plurality of third connecting holes 4121 are provided on the second straight rod section 412 of the connecting rod 410, and the plurality of third connecting holes 4121 are evenly distributed in the vertical direction. A third positioning hole 421 is provided on the fine-tuning rod 420. Figure 6 As shown, the third positioning connector 900 passes through the third positioning hole 421 and connects to one of the third connecting holes 4121. Specifically, the third positioning connector 900 is a locking pin or a bolt. When the third positioning connector 900 is a bolt, the stud section of the bolt passes through the third positioning hole 421 and the third connecting hole 4121 and is screwed to a nut. Thus, when the third positioning connector 900 is connected to different third connecting holes 4121, the connection position of the fine-tuning rod 420 on the connecting rod 410 is different, resulting in different heights of the fine-tuning rod 420. This adjusts the height of the fine-tuning rod 420 relative to the connecting rod 410, thereby adjusting the height of the entire second adjusting rod 400.

[0076] More preferably, in this embodiment, an elastic element is also provided between the support 600 and the mounting platform 500. Optionally, the elastic element is a spring 1000; of course, the elastic element can also be an airbag or a flexible pad.

[0077] With the help of the aforementioned elastic element, the support 600 can move slightly vertically, equivalent to the mounting platform 500, thus allowing the support 600 a certain degree of freedom of movement in the vertical direction. This avoids severe restriction of the head and neck of patients wearing this head, neck, and chest orthosis.

[0078] When the patient performs mouth movements, such as eating, speaking, sneezing, or coughing, the support 600 can move slightly to prevent the mandibular movement from creating a reaction force on the mandibular support, which could lead to unstable displacement of the cervical spine, harming the lesion, or increasing the risk of vertebral displacement. At the same time, the slightly movable support 600 makes the head, neck, and chest orthosis more comfortable for patients wearing the device, thereby improving patient compliance during treatment.

[0079] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
