Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments of the application. In the drawings, like reference numerals describe substantially similar components throughout the different views. Various specific embodiments of the application are described in sufficient detail below to enable those skilled in the art to practice the teachings of the application. It is to be understood that other embodiments may be utilized or structural, logical, or electrical changes may be made to embodiments of the present application.
The technical scheme of the application is further described by the specific embodiments. It should be understood by those skilled in the art that the following descriptions are only for convenience in understanding the technical solutions of the present application and should not be used to limit the scope of the present application.
The application provides an orthopedic support, which is supported by placing an elastic part between spinous processes, so that the height between the spinous processes can be restored, and the effect of reducing pressure is achieved, wherein the elastic part placed between the spinous processes respectively clamps and fixes adjacent spinous processes by utilizing a self structure, and the orthopedic support can be prevented from sliding down without binding belts or bone nails, so that the movement stability and the controllable movement of a lumbar structure are realized. The orthopedic support also comprises a vertebral plate support piece for supporting and fixing the spinous process piece, so that the support between vertebral plates can be realized while the spinous process support is realized, and the orthopedic support piece plays an important role in maintaining the stability of the vertebral column, dispersing pressure, recovering and maintaining normal curvature of the vertebral column, promoting healing, relieving pain, preventing herniation of the intervertebral disc, improving functions and the like.
Since the spinous process is a plate-like bone with one end engaged with the spinal column and the other end extending away from the spinal column, a plane in which the spinous process extends and a plane perpendicular thereto may be defined for convenience of the following description.
Fig. 1 is a schematic side view of an orthopedic support according to one embodiment of the present application.
Fig. 2 is a schematic front view of the orthopedic support shown in fig. 1 according to one embodiment of the present application.
According to one embodiment, the orthopedic support includes a lamina support 20 and a spinous process support 10.
According to one embodiment, the spinous process support 10 comprises a first portion 101, a second portion 102, and a third portion 103, wherein the spinous process support 10 third portion 103 is connected between the first portion 101 and the second portion 102. According to one embodiment, the first portion 101 and the second portion 102 extend in opposite directions, in particular the first portion 101 extends in a direction towards the upper side of the first spinous process and the second portion 102 extends in a direction towards the lower side of the second spinous process.
According to one embodiment, the projection of the third portion 103 of the spinous process support 10 in a plane perpendicular to the plane of the spinous process extension may have a substantially inverted trapezoidal shape, i.e., a shape with a wider upper portion and a narrower lower portion. According to one embodiment, the first and second surfaces 1031, 1032 of the third portion 103 of the spinous process support 10 have arcuate surfaces that oppose each other, wherein the first surface 1031 may have an arcuate surface that is greater than the arcuate surface of the second surface 1032. According to one embodiment, the first surface 1031 of the third portion 103 is coupled to the first portion 101 and the second surface 1032 of the third portion 103 is coupled to the second portion 102 for supporting or contacting two adjacent spinous processes, respectively. The spinous process support 10 is connected to the lamina support 20 at an end adjacent to the spinal column.
According to one embodiment, the size of the space formed between the first portion 101 and the second portion 102, i.e., the size of the third portion 103, can be adjusted as desired, thus solving the problem of different spinous process sizes for different users.
According to one embodiment, the inside of the third portion 103 of the spinous process support 10 may be solid or hollow, and in the hollow case, an opening may be provided on the surface of the third portion 103 at a proper position, and the air inside the third portion 103 is released through the opening during operation, so as to be placed between spinous processes without affecting the subsequent support effect.
According to one embodiment, the first portion 101 may include two sub-portions located on the left and right sides of the first spinous process, and the two sub-portions may be symmetrically distributed. According to one embodiment, the two sub-portions of the first portion 101 of the spinous process support 10 may be approximately oval in shape, the two sub-portions becoming smaller in size and smaller in size at the spatial opening location, and the inner surfaces of the two sub-portions conforming in shape to the spinous process surface with which they are in contact.
The space therebetween can accommodate the first spinous process. According to one embodiment, the two sub-portions may not be closed to each other, the space between them opening away from said third portion 103. Also, according to one embodiment, the distance between the two sub-portions, at least at the location of the spatial opening between the two, may be less than the width of the first spinous process at that location, which may provide for better spacing and fixation of the spinous processes. Since the material of the orthopedic support is an elastic material, the two sub-portions can be spread apart to accommodate the first spinous process as it is inserted into the space. Since the first portion 101 mainly contacts the lower surface and both sides of the first spinous process, which in turn has a gradually changing shape with a small upper part and a large lower part, the distance between the two sub-portions of the first portion 101 may be gradually reduced upward along the spinous process.
According to another embodiment, the two sub-portions of the first portion 101 may close or contact or engage each other over the upper edge of the spinous process.
According to one embodiment, the second portion 102 of the spinous process support 10 may include two sub-portions, which may be symmetrically distributed. The space therebetween can accommodate the second spinous process. According to one embodiment, the two sub-portions may not be closed to each other, the space between them opening away from said third portion 103. Also, according to one embodiment, the distance between the two sub-portions, at least at the location of the spatial opening between the two, may be less than the width of the second spinous process at that location, which may provide for better spacing and fixation of the spinous processes. Since the material of the orthopedic support is an elastic material, the two sub-portions can be distracted for accommodation when the second spinous process is inserted into the isolated space. Since the second portion 102 is primarily in contact with the superior surface and sides of the second spinous process, which in turn has a gradually changing shape with a small top and a large bottom, the distance between the two sub-portions of the second portion 102 may gradually increase down the spinous process.
According to one embodiment, each sub-portion of the second portion 102 of the spinous process support 10 may be approximately trapezoidal in shape, with a long side near the third portion 103, a short side away from the third portion 103, and an inner surface conforming to the shape of the contacting spinous process surface.
Of course, according to another embodiment, the two sub-portions of the second portion 102 may also have a substantially symmetrical shape and positional relationship with the two sub-portions of the first portion 101.
According to one embodiment, the first portion 101, the second portion 102, and the third portion 103 of the spinous process support 10 may be integrally formed.
Since the first portion 101 and the second portion 102 of the spinous process support 10 are respectively fixed to different spinous processes, the effect of supporting the spinous processes can be ensured, and the range of motion of the patient can be not limited. In addition, the first portion 101 and the second portion 102 of the spinous process support 10 have an open structure, which can fix the basic position of the spinous process and avoid excessively dead binding of the spinous process, thus providing a certain flexibility and stability to the user, compared to the binding band.
According to one embodiment, the first portion 101 and the second portion 102 of the spinous process support 10 may also be spinous process sleeves (not shown) wrapped around the spinous process. According to one embodiment, the spinous process covering may be made of a resiliently flexible material. According to one embodiment, the dimension of the spinous process sleeve when not stretched is smaller than the spinous process dimension, and when the spinous process sleeve is stretched and sleeved on the spinous process, the spinous process can be firmly fixed without affecting the spinous process flexibility.
