A fixed bracket for calcaneal measurement

Abstract

The invention discloses a fixed bracket for calcaneus measurement, which comprises a base, a bracket rod and an extension rod. The first threaded rod, one end of the first threaded rod penetrates the inner wall of the rotating groove and is fixedly connected with the first rotating block, the connecting block is threaded on the first threaded rod, and the top end of the connecting block is fixedly connected with a rotating block, one end of the bracket rod is connected to the rotating block in rotation, and the end of the base away from the rotating groove is provided with a rotating cavity, and a second threaded rod is rotatably connected in the rotating cavity, and the second threaded rod One end runs through the rotating cavity and is fixedly connected with the second rotating block. The present invention can well determine the anatomical posture of the isolated calcaneus, realize better anatomical measurement, especially the measurement of the inclination of the anatomical structure of the calcaneus, and make the data more convincing.

Description

Technical field [0001] The present invention relates to the field of bone measuring related articles, in particular a fixed bracket having a heel measurement. Background technique [0002] The measurement of the varying body and bone needs to restore its anatomical posture as much as possible, but the anatomical posture is not normal to the bone separation, and it is now known that there is a bone inclined angle in the corner of the corner, and the back bow. Corner (normal value:> 16 °), measurement method: from the lowest point of the rose joint to the lowest point of the calcium bone, then a straight line from the lowest point to the 5th metatars, then measure two straight lines In enough angle, existing condensation operations are more complicated, lacking a device to assist measurement, so that the measurement efficiency is lowered and has defective. Inventive content [0003] It is an object of the present invention to provide an anatomical posture of a fixed bracket tha...

AI Technical Summary

Problems solved by technology

[0002] The measurement of the isolated calcaneus needs to restore its anatomical posture as much as possible, but the anatomical posture cannot be defined normally after the calcaneus is separated from the body. Now we can know from literature review that there is a calcaneus inclination angle in the arch angle of the foot, that is, the transverse arch and the posterior arch. Angle (normal value: >16°), measurement method: draw a straight line from the lowest point of the calcaneocuboid joint to the lowest point of the calcaneus, then draw a straight line from the lowest point of the calcaneus to the lowest point of the fifth metatarsal head, and then measure two straight lines Due to the angle formed, the existing calcaneus measurement operation is relatively complicated, and there is a lack of auxiliary measurement devices, which reduces the measurement efficiency and is defective
