Problems solved by technology

However, it is impossible to ensure that the limbs are in the same position every time the film is taken, which may easily cause the angle of the limbs to change, resulting in inconsistencies in the measurement before and after

Abstract

The invention relates to the technical field of Stewart platform parameter solution, and more specifically, relates to a CT scanning based measurement method for Taylor stent parameters. The method includes the following steps: S1, putting a Taylor stent on the broken deformed leg bone of a patient through an operation, selecting rings with different sizes and supporting rods with different lengths according to the deformed part and specific circumstances of fracture, and performing individualized installation; and S2, performing CT scanning on the installed Taylor stent deformed leg bone anda correspondingly healthy leg bone, obtaining a DICOM format file, performing three-dimensional reconstruction to export a three-dimensional model, and removing soft tissue and other interference factors. The method can perform precise corrective repositioning on fracture deformity, is good for fracture healing and the functional recovery of ill limbs and has high medical values and social benefits.

Description

technical field [0001] The invention relates to the technical field of solving Stewart platform parameters, more specifically, it relates to a method for measuring Taylor bracket parameters based on CT scanning. Background technique [0002] At present, external fixator, as a micro-invasive tool for reduction and fixation, is more and more widely used. It can provide a fast and effective treatment for complex traumatic fractures. It has many irreplaceable advantages of internal fixation, and its trauma is small. , wide indications, can provide stable and elastic fixation for broken bone. In 1994, Harold S.Taylor improved the Ilizarow external fixator system based on the Stewart platform and Charles theorem and used it in the field of bone external fixation, forming the Taylor space external fixation bracket. [0003] Taylor's outer space fixed bracket has 6 telescopic support rods, both ends of which are connected to the fixed ring, and can rotate freely at the connection. ...
