Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an adjustable fixation brace. Background Technology

[0002] Developmental dysplasia of the hip (DDH) is one of the most common musculoskeletal deformities in infants and young children. For children older than 6 months or those who have failed initial bracing treatment, the clinical treatment plan is often "closed reduction + hip spica cast fixation". This plan maintains the stable reduction of the femoral head in the acetabulum by forcibly fixing the hip joint in a specific body position (i.e., high flexion and abduction), thus creating a chemical environment for the normal development of the acetabulum.

[0003] However, traditional hip spica casts have many inherent drawbacks, which seriously affect treatment outcomes, child comfort, and the family care experience:

[0004] Fixed and rigid, unable to be adjusted: Once the plaster cast has hardened, the fixed angles of the hip and knee joints cannot be changed. Throughout the entire treatment period, which can last for several months, no fine-tuning of the angles can be made based on changes in the stability of the reduction or the child's growth and development, lacking personalization and adaptability.

[0005] Nursing care is difficult, and the risk of complications is high: The plaster cast is heavy, non-breathable, and cannot be removed, making it difficult to clean the child's skin and easily leading to eczema, pressure sores, and even infections. In addition, the heavy plaster cast also seriously hinders the child's daily activities, sleep, and the parents' care.

[0006] Impeded growth and follow-up examinations: Infants and young children grow rapidly, and the fixed plaster cast often becomes tight quickly as the limbs thicken and lengthen, which may affect blood circulation in the limbs. Moreover, it is necessary to completely remove and remake the cast to adapt to the growth, which is a complicated process and increases the child's pain. At the same time, the plaster cast seriously interferes with X-ray images, affecting the doctor's accurate assessment of the reduction quality.

[0007] To overcome the shortcomings of plaster casts, some adjustable bracing devices have emerged in the current technology. However, these devices typically offer only limited and coarse angle adjustment functions (such as a few preset positions), lacking a precise, continuous, and quantifiable angle adjustment mechanism. The adjustment process often relies on the physician's experience and feel, failing to achieve precise angle setting and reproduction based on imaging follow-up results, and exhibiting insufficient stability and reliability of the joint locking structure after adjustment. Furthermore, existing adjustable braces still have significant shortcomings in terms of breathability, lightweight design, and intelligent monitoring.

[0008] Therefore, in order to solve the problem of the inability to adjust the angle, this invention designs an adjustable fixed brace to achieve adjustment of the hip and knee joint angles of the relevant brace. Summary of the Invention

[0038] When using the present invention, the specific technical effects brought about by the embodiments are as follows: After a child with congenital hip dysplasia is repositioned and fitted with a fixation brace, when it is necessary to adjust the angle of the child's hip and knee joints after a period of time, the angle is changed by adjusting the knee joint adjustment part and the hip joint adjustment part. First, adjust the knee joint adjustment part. Start by adjusting the limiting component in its limited position. By pressing down on the first pushing part, the second spring is compressed by the retaining ring on the first pushing part, putting it in a tightened state. At this point, the second pushing part is pushed deep into the first opening in the first fixing part. Releasing the first pushing part causes the second spring to rebound, moving the first pushing part upwards and extending it out of the first opening. The locking block engaging with the third sawtooth is also lifted accordingly, putting the knee joint adjustment part in a rotatable state. Rotating the third fixing part along the groove adjusts the knee joint adjustment. The second sawtooth outside the knee joint adjustment part rotates the engaging first sawtooth, which in turn rotates the first connecting part, thus rotating the lower leg brace and adjusting the knee joint angle. After adjusting the knee joint angle, push the first pushing part in the limiting component downwards, pushing the second pushing part on the limiting component into the first opening in the first fixing part and fixing it in place, thus completing the knee joint adjustment. The limiting mechanism of the hip brace allows for adjustment of the knee joint angle. When adjusting the hip brace angle, the hip joint adjustment mechanism needs to be adjusted. First, the adjustment mechanism is rotated. The adjustment mechanism, which is in a depressed state, is rotated. Since the adjustment mechanism rotates around an eccentric screw, it will be adjusted to a raised state. At this time, the adjustment mechanism does not press down on the upper rotating part, so the upper rotating part is lifted upward by the third spring, moving it away from the lower rotating part it meshes with. This allows the lower rotating part to rotate around the support column. Since the lower rotating part is connected to the connecting part, it drives the connecting part to adjust its angle, thereby driving the thigh brace to rotate and adjusting the angle between the thigh brace and the hip brace. After adjustment, the adjustment mechanism is rotated back to the depressed state, causing the upper rotating part to be pressed down to the position where it meshes with the upper rotating part, preventing the lower rotating part from rotating. The adjustment mechanism is then fixed by screwing a screw into the first screw hole in the support column to prevent the adjustment mechanism from springing back, thus achieving adjustment of the hip brace angle.

[0039] In summary, this invention improves upon traditional fixation braces, allowing doctors to adjust the knee and hip joint angles of the brace according to the recovery progress during correction, avoiding the need for brace disassembly and effectively achieving multi-angle adjustment of traditional fixation braces.

[0040] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0042] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
