a bone or joint fixation device

Abstract

The invention provides a novel bone and joint fixation instrument which comprises a plurality of unequal-sized rigid units. Each rigid unit is provided with a central hole, and the rigid units are strung together through a metal chain or a metal rope in a zigzag mode. The novel bone and joint fixation instrument is further provided with a tensioning and locating mechanism for the metal chain or the metal rope, extruding structures of the rigid units are arranged on the zigzag part and the head and the tail of the string, the head portion and the tail portion of each rigid unit are both provided with joint spherical surfaces, and the adjacent rigid units form sliding fit capable of being adjusted three-dimensionally. The novel bone and joint fixation instrument can be applied to the occasions of fractures, dislocation, damage of muscles, tendons, fascias and ligaments, congenital or posteriority malformations and the like, and assists skeleton connection or fixation, further, the novel bone and joint fixation instrument is free of wasting time for forming and solidifying like former materials, is free of complex preparation steps, and can be used repeatedly, and pollution on the environment cannot be caused.

Description

technical field [0001] The present invention relates to a fixation device, in particular to a fixation machine of a rigid structure that helps bone connection or fixation in fractures, dislocations, injuries of muscles, tendons, fascia, ligaments, congenital or acquired deformities, and the like. Background technique [0002] In clinical practice, there will be various situations and environments, such as fractures, dislocations, injuries of muscles, tendons, fascia, ligaments, congenital or acquired deformities, which must be treated with bone connection and fixation. Plaster casts have been used as a bone fixation device for over a hundred years and are still the standard fixation device in many countries. But it is not without flaws, such as heavy weight, slow curing time of more than ten hours, etc. In recent years, synthetic resins (urethane resins) have become widely used and have established themselves in orthopedic care in developed countries. Although resin-cast s...

AI Technical Summary

Problems solved by technology

The catalyst needed for splinting can irritate the skin and even cause an allergic reaction

Both plaster and synthetic resins require sufficient time to form and cure, require complex preparation steps and are cumbersome to apply

Moreover, these fixtures need to be removed from the patient and discarded after they are used up, and the waste will also cause environmental pollution
