Embodiment 1

[0038] figure 1 It shows the relative relationship between the ankle and the device during use. In order to facilitate the understanding of the three dimensions of the ankle, as well as the length, width and height of the ankle, figure 2 The coordinate system is illustrated. The X-axis of the coordinate system, that is, the horizontal direction, is the width direction of the ankle; the Y-axis of the coordinate system, that is, the longitudinal direction, is the length direction of the ankle; the Z-axis of the coordinate system, that is, the vertical direction, is the height direction of the ankle. Point A is the outermost side of the first metatarsal bone, point B is the outermost side of the root bone, and points C and D are any two points on the front side of the tibia.

[0039] An adjustable three-dimensional positioning device, which includes a positioning platform 1, and two longitudinal slide rails 3 are symmetrically fixed on the left and right sides of the positioni...

Embodiment 2

[0050] In the first step, step the ankle on the positioning platform 1 and adjust the position of the ankle so that point B on the outside of the root bone contacts the root bone positioning member 2 .

[0051] The second step is to adjust the position of the tibial vertical positioning slider on the longitudinal slide rail so that the tibia contacts the two inductors 10 on the tibial vertical positioning part 9 at the same time, and the tibial vertical positioning slider is fixed by using a set bolt. fixed.

[0052]The third step is to move the longitudinal positioning slider 4 on the lateral side of the first metatarsal bone on the longitudinal sliding rail 3 to align with point A on the lateral side of the first metatarsal bone of the ankle, and then place the lateral positioning slider 6 on the lateral side of the first metatarsal bone Move on the positioning slide rail 5, so that the lateral positioning slide block 6 on the lateral side of the first metatarsal contacts th...

Abstract

The invention discloses an ankle positioning device, and particularly relates to an adjustable three-dimensional positioning device and a using method thereof. The adjustable three-dimensional positioning device comprises a platform, a sliding rail, an ankle root bone positioning piece, a first metatarsal bone positioning slider and a tibia positioning system. An ankle is transversely, longitudinally and vertically positioned by using the root bone positioning piece, a first tibia outside positioning piece, a tibia positioning piece and the like, the positioning method is objective and scientific, the positioning gesture is easy to maintain, and the positioning information is easy to set and read. The deficiencies are made up for that in an existing orthotic insole custom-tailored production process, the neutral position of the ankle during standing is difficult to maintain, the ankle morphology data is difficult to measure, and a measurement error is large.

Description

technical field [0001] The invention relates to an adjustable three-dimensional positioning device and a using method thereof. Background technique [0002] When making personalized orthotic insoles, it is necessary to locate and then measure the shape of the patient's ankle. The common method currently used is that the patient lies on the bed, and the production master adjusts the ankle to the neutral standing position of the human body through observation, and then marks and measures the ankle. The master maker uses the shape of the ankle in this state as a mold to make the orthotic insole. Due to the observation method, the subjective factors are relatively large, so the error of this method is very large. The same master makes several positioning measurements on the same patient, and the results may be different each time. Different production masters make positioning measurements on the same patient, and the results may also be different. In addition, it takes a cer...
