A cable type internal fixation device for orthopedics

Abstract

The invention relates to a rope type internal fixation device for the orthopedics department. The rope type internal fixation device comprises a rope and fixation nails, wherein the rope is formed by weaving fibers and provided with a fixation band. The two ends of the fixation band are respectively provided with a fixation ring. The fixation nails are inserted into the fixation rings. The fixation nails are hollow and provided with hollow axial channels. The end face area of the ends, connected with nail bodies, of nail heads is larger than the end face area of the ends, connected with the nail heads, of the nail bodies. The rope type internal fixation device is a novel growth guiding internal fixation device, has flexibility compared with a steel plate, can be suitable for the metaphysis in any anatomical shape, has lower incisurae and higher biomechanical strength and makes placement of the screws more convenient, and therefore the problems that for a current steel plate shaped like the Arabic number eight, screws are often pulled out and fractured and are complicated to place in and take out are effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cable-type internal fixation device for orthopedics. Background technique [0002] The normal growth of children's bones depends on the combined effects of genes, hormones and biomechanics. These factors jointly regulate or regulate the growth of the epiphyseal plate, maintain the continuous growth of bones during childhood, and form a normal anatomy suitable for children's age at different ages axes and mechanical lines of force. However, during the rather long growth process, especially the growth of lower extremity bones is often faced with the threat or intrusion of trauma, infection, and some metabolic diseases, which may produce shortening, angulation, and rotational deformities, thus changing the anatomical axis of the lower extremities and The mechanical line of force, or the unequal length of the lower limbs, leads to abnormal gait and joint dysfunction, w...

AI Technical Summary

Problems solved by technology

[0005] However, in the current clinical use of 8-shaped steel plates, there are often problems such as the shape of the plate does not fit the shape of the epiphysis, causing the screws to pull out or break, and the insertion and removal process is cumbersome. Therefore, there is an urgent need for a new type of growth guidance for pediatric orthopedics internal fixation device
