Bone Stabilization Apparatus for Accurate Orthopedic Reaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current stabilization and guiding devices for reaming bone elements during orthopedic implantation procedures lack stability and accuracy, leading to potential misalignment and shifting of bone elements.
Innovation Solution
A stabilization apparatus comprising an outer sleeve with a soft tissue protection element and support rod apertures, and an inner sleeve with a pilot hole guide portion, which includes interlocking mechanical devices to secure the apparatus relative to the bone elements, ensuring precise orientation and protection of soft tissues during reaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stabilization devices are used to secure the apparatus to bone elements, then stability and accuracy are improved, but device complexity increases due to multiple components including inner sleeve, outer sleeve, and support rods
Solution Approach 1:
The inner sleeve is nested within the outer sleeve, with the inner sleeve's outer surface fitting within the outer sleeve's inner surface. This nested configuration allows multiple functional components to be integrated in a compact arrangement, providing stabilization through support rods while maintaining a space-efficient design that reduces overall device complexity.
Solution Approach 2:
The stabilization device is divided into distinct functional segments: the outer sleeve with support rod apertures for stabilization, the inner sleeve with pilot hole guide portion for guidance, and the interlocking mechanical devices. This segmentation allows each component to perform its specific function independently while working together as an integrated system, improving reliability without requiring a monolithic complex structure.
2Measurement precision
If support rods are used to affix the apparatus, then positioning accuracy is improved, but the number of components and assembly steps increases
Solution Approach 1:
The outer sleeve serves multiple functions: it provides structural support, contains the support rod apertures for positioning, and integrates the interlocking mechanical device with the inner sleeve. This multi-functionality reduces the need for separate components, achieving positioning accuracy through support rods while minimizing the overall number of parts.
Solution Approach 2:
The interlocking mechanical device merges the connection function between the inner sleeve and outer sleeve into a single integrated mechanism. This combining of functions reduces the number of separate components needed for assembly, while the support rods embedded in the outer sleeve provide the necessary positioning accuracy without requiring additional separate fixation elements.

AI summary
Systems, methods, and apparatuses for reaming bone elements are provided. The implantation of orthopedic implanted devices for fusion, stabilization, and fixation of joints, fractures, and other fusions involves various complicated processes and components. The reaming of bone elements for implantation of orthopedic implanted devices often requires an assistant physically stabilizing the bone elements, which may easily lead to shifting and/or misalignment of bone elements during the reaming procedure.
