Taylor external fixing stent

Abstract

The invention relates to the technical field of medical devices, and provides a Taylor external fixing stent which includes a proximal ring, a distal ring and a plurality of adjustment extension rods.The proximal ring and the distal ring are correspondingly provided with six lug rings, and the adjustment extension rods are correspondingly connected to the lug rings of the proximal end and the distal ring through universal joints at the two ends. Bone needles II are installed on the upper and lower sides of the proximal ring correspondingly, and bone needles I are further installed on the upper side of the proximal ring. Bone needles II are installed on the upper side and the lower side of the distal ring, and bone needles I are further installed on the lower side of the distal ring. The bone needles I are threadedly connected with a human bone, and the bone needles II penetrate through the human bone. The Taylor external fixing stent has the beneficial effects that the adjustment extension rods can be selected to be installed on the proximal ring and the distal ring according to the needs of the operation to meet the requirements of the operation; and meanwhile, the two kinds of the bone needles can further use fixed needle seats and columns to adjust the installation position and installation height.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a Taylor external fixator. Background technique [0002] Taylor first applied the Stewart platform and Chasles theory to orthopedics, improved the ilizarov external fixation system, and used six flexible support rods that can rotate freely at the joints to connect the distal and proximal fixation rings. This external fixation system is called Taylor. Fixed bracket outside the space. The Taylor space external fixation bracket consists of two full or partial rings, which are connected by 6 telescopic support rods through universal joints. Only by adjusting the length of the support rods, one ring can be repositioned relative to the other. Combining this frame structure with a special software program, it can accurately treat various fracture displacements, nonunions and malunions clinically. With continuous improvement and perfection, the concept of de...

AI Technical Summary

Problems solved by technology

However, the installation process is relatively complicated, and generally requires individualized installation. Olive needles and thin Kirschner wires are often used as fixed needles, and the number of steel needles, needle insertion direction, span, and limb conditions need to be considered

In addition, the installation process of the bracket is relatively complicated, and proper adjustments, configuration changes, and addition of components are required to successfully complete the complex and deformed installation

And after the bracket is installed, the angle of the bracket and the change of the distance need to be adjusted by adjusting the length of the support rods, while the ordinary Taylor bracket has at least 6 adjustment rods. higher
