Mixed external fixer based on needle flexible adjustment

Abstract

The invention discloses a mixed external fixer based on needle flexible adjustment, and can be applied to the field of orthopedic surgery. A ring is connected with a fixed rod through a fixed rod clamp; the ring can realize adjustment in the longitudinal direction through the fixed rod; a ring fixed line clamp and a ring fixed needle clamp are connected with the ring; the fact that humerus is fixed in the ring at any angle can be realized; the ring fixed needle clamp can realize fixing of a tibia joint in the ring at any angle, and can realize position adjustment and positioning in the longitudinal direction of the fixed rod. A double-needle clamp and a single-needle clamp mainly realize the fixing of a tibia part, and can realize 360-degree angle positioning around the fixed rod and fixing in the longitudinal direction of the fixed rod. A phalanx needle realizes 360-degree angle adjustment around the fixed rod and fixing in the longitudinal direction. The mixed external fixer is largein adjustment range and high in flexibility, can be applied to multiple parts, such as humerus, tibia and phalanx, at the same time, meanwhile solves the problems that needle flexible adjustment andaccurate positioning are difficult, and is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the field of orthopedic rehabilitation medical equipment, and in particular relates to a flexible-adjustable hybrid external fixator device based on needles. Background technique [0002] Human lower extremity fractures are a common orthopedic disease with a large number. The traditional method of treating this disease is immobilization with plaster, traction or open reduction and internal fixation. With the development of external fixation technology, external fixation bracket has become one of the more important tools in orthopedic treatment and has been widely used. , they basically hold the broken bones tightly together. These external fixators are not only a relatively rough splint or cast, but also include a variety of more modern and complex external fixation systems, including Llizarow ring external fixator, tubular external fixator, and unilateral powered unilateral external fixator. fixer etc. These commonly used ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a hybrid external fixator that has a large needle adjustment range and great flexibility and can be applied to multiple parts such as the humerus, tibia, and phalanges at the same time, to solve the problem of flexible adjustment and precise positioning of the needle problems, and the structure is simple and easy to use
