[0029] To better understand this utility model, it will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] An orthotic joint axis structure includes a base 1, a hollow rod 8, and an adjustment frame;

[0031] A vertical hollow rod 8 is installed on the base 1, and the hollow rod 8 has scale lines along its length.

[0032] The adjustment frame includes a control console 5 and a positioning rod 7;

[0033] The control console 5 is mounted on the hollow rod 8;

[0034] A laser emitter is placed on the control console 5;

[0035] There are two positioning rods 7, which are arranged vertically and symmetrically on both sides of the control console 5. The upper end of the positioning rod 7 is connected to the control console 5, and the positioning rod 7 is provided with scale lines; the lower end of the positioning rod 7 is provided with a positioning hole 6.

[0036] In this invention, when the control console 5 is adjusted to a suitable position, the operator can use an electric rotary tool to drill and position the molds used for making orthotics on both sides of the shaft structure through the positioning holes 6.

[0037] Preferably, the upper end of the hollow rod 8 is further connected to a coaxial vertical extension rod 3, and the control console 5 is adapted to the extension rod 3, allowing the control console 5 to move up and down along the extension rod 3; the extension rod 3 has scale lines along its length. In this invention, the extension rod 3 and the hollow rod 8 are connected by a snap-fit ​​structure; the design of the extension rod 3 improves the adjustment range.

[0038] In this invention, the length of the hollow rod 8 is 40-50cm, preferably 45cm; the length of the extension rod 3 is 35-45cm, preferably 40cm; and the length of the positioning rod 7 is 30-40cm, preferably 35cm.

[0039] Preferably, the console 5 is equipped with a height limiting member, which is located on the hollow rod 8 or the extension rod 3.

[0040] Preferably, the control console 5 has a ring-shaped structure, including an inner ring 10 and an outer ring 9 connected by a connecting rod 2, and the laser emitter is disposed in the space between the inner ring 10 and the outer ring 9; the inner ring 10 of the control console 5 is adapted to the hollow rod 8 and the extension rod 3, and the inner ring 10 of the control console 5 can move vertically along the hollow rod 8 and the extension rod 3.

[0041] In this invention, the limiting component is a tube clamp 4, which is an existing structure. After the control console 5 is adjusted into position on the hollow rod 8 (or extension rod 3), the tube clamp 4 engages with the hollow rod 8 (or extension rod 3) at the lower part of the control console 5, abutting against the lower part of the control console 5. At this time, the control console 5 cannot move downward under the action of the tube clamp 4, thus achieving the limiting of the control console 5. The laser emitter is an existing mature structure and will not be described in detail here.

[0042] Example

[0043] like Figure 1 The orthotic joint alignment structure shown includes a base 1, an extension rod 3, a clamp 4, a control console 5, and a positioning hole 6. The base 1 is a disc-shaped structure with a diameter of 4 cm. A hollow rod 8, 45 cm long and 2 cm in diameter, extends vertically upwards from the base 1. Scale lines are marked along the length of the hollow rod 8. The extension rod 3 is 40 cm long and also marked with scale lines. The extension rod 3 is connected to the hollow rod 8 of the base 1 via a snap-fit ​​structure. The clamp 4, with a diameter of 2 cm, is mounted on the hollow rod 8 and is used to fix the position of the control console 5. Figure 2 As shown, the control console 5 has a ring-shaped structure, including an inner ring 10, an outer ring 9, and three connecting rods 2 connecting the inner ring 10 and the outer ring 9; the inner ring 10 has a diameter of 2.5cm, which is adapted to the hollow rod 8 and the extension rod 3. The inner ring 10 is fitted over the hollow rod 8 (or the extension rod 3), allowing the control console 5 to move up and down along the hollow rod 8 (or the extension rod 3), and is limited by the tube clamp 4; the positioning hole 6 is located at the end of the positioning rod 7, and has a diameter of 1cm, such as... Figure 3 As shown.

[0044] In this embodiment, after the extension rod 3 is connected to the hollow rod 8 of the base 1, the height of the shaft structure can be adjusted between 45 and 85 cm.

[0045] In this embodiment, a small laser emitter is installed in the space between the inner ring 10 and the outer ring 9 of the console 5.

[0046] This embodiment uses the fabrication of an ankle-foot orthosis as an example to illustrate its working principle. The negative mold (i.e., the template) used to fabricate the ankle-foot orthosis includes a foot template adapted to the foot and a leg template adapted to the leg. A method for fabricating an ankle-foot orthosis based on the joint-axis structure of the orthosis is provided, the method being:

[0047] First, place the base 1 on the inner bottom surface of the ankle-foot orthosis (i.e., the foot template of the mold, on which reference lines for the front and back positions of the ankle joint axis of the orthosis are set, the front and back direction being the direction from the toe to the heel), as the supporting foundation for the entire axis structure; the hollow rod 8 extending vertically upward from the center of the base 1 not only provides support but also provides a reference for the installation and adjustment of subsequent components; according to the ankle joint axis height parameters to be positioned by the user, connect the extension rod 3 to the hollow rod 8 of the base 1 through a snap-fit ​​structure, adjust the overall length of the axis structure, and make the height between the positioning hole 6 at the lower end of the positioning rod 7 and the foot template close to the ankle joint axis height to be positioned by the user;

[0048] Then, roughly adjust the height of the control console 5 to a suitable position on the hollow rod 8. After the height is adjusted to the correct position, use the tube clamp 4 to fix the control console 5 to the hollow rod 8 of the base 1. Install a laser emitter in the platform space between the inner ring 10 and the outer ring 9 of the control console 5. The laser emitter can emit a vertically downward square-shaped laser line. According to the projection of the square-shaped laser line on the foot template of the mold and the reference line of the front and back position of the ankle joint axis of the orthosis on the foot template, adjust the position of the base 1 on the foot template so that the front and back positions of the ankle joint axis on the inner and outer sides of the ankle-foot orthosis are consistent.

[0049] Next, the height of the console 5 is further fine-tuned to ensure that the height of the ankle joint axis on both the inner and outer sides is the same and consistent with the ankle joint axis height parameter required by the user (the height of the positioning hole 6 can be calculated by the scale line on the hollow rod 8 and the scale line on the positioning rod 7).

[0050] Finally, using the positioning hole 6 located at the lower end of the positioning rod 7, holes are drilled at corresponding positions on both sides of the leg template of the ankle-foot orthosis mold to provide a precise reference for the subsequent fabrication of the dynamic orthosis.

[0051] When this utility model is used to assist in the production of knee-ankle-foot orthoses, since the knee joint axis is relatively high, the control console 5 is set on the extension rod 3 through the tube clamp 4, and holes are punched in the leg template of the knee-ankle-foot orthose mold according to the knee joint axis height parameter; other operations are the same as those for making ankle-foot orthoses.

[0052] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0053] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
