Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone fixation technologies face challenges in achieving optimal implant placement and maintaining uniform force distribution across bone surfaces, requiring additional manipulation post-insertion and lacking efficient instrumentation for proper placement and function.
Innovation Solution
A bone staple and inserter system with elastic properties, allowing the staple to be pre-assembled with the inserter for facilitated placement, maintaining a first configuration during insertion, and transitioning to a second configuration post-placement, utilizing shape memory or super elastic materials to generate multi-directional forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the implant is inserted directly without pre-assembly, then the insertion process is simpler, but additional manipulation post-insertion is required to achieve optimal placement and force distribution
Solution Approach 1:
The implant is pre-assembled with the inserter device before insertion, configuring the implant in a first state that facilitates straightforward insertion. This preliminary configuration eliminates the need for complex post-insertion manipulation while ensuring optimal placement and force distribution is achieved automatically upon insertion.
2Device complexity
If the implant uses a single configuration, then the device structure is simpler, but it cannot maintain uniform force distribution across bone surfaces
Solution Approach 1:
The implant is designed with multiple configurations that allow it to transition dynamically. The implant starts in a first configuration during insertion for simplicity, then transitions to a second configuration post-insertion that maintains uniform force distribution across bone surfaces, combining structural simplicity with functional reliability.
3Strength
If the implant is made rigid for stable fixation, then fixation stability is improved, but the implant cannot be pre-assembled with the inserter for facilitated placement
Solution Approach 1:
The implant utilizes changes in physical parameters, specifically flexibility, to resolve the contradiction. The implant is made from elastic or shape memory materials that allow it to be flexible during pre-assembly and insertion, then transition to a rigid state post-insertion to provide stable fixation, achieving both ease of operation and fixation stability.

Function Achieved in This Case
Enables precise and efficient implant placement without additional manipulation, maintaining uniform force distribution across bone surfaces, and allowing for reconfiguration post-insertion, enhancing the stability and effectiveness of bone fixation.
Implementation Method 1
The staple is made from high elasticity materials such as nitinol and/or polyetheretherketone (PEEK) so that the staple may be elastically deformed by an external force, and then resume the free state when the external force is removed.
Implementation Method 2
utilizing shape memory or super elastic materials to generate multi-directional forces
Implementation Method 3
utilizing shape memory or super elastic materials to generate multi-directional forces

AI summary
An assembly used in osteosynthesis comprising a delivery instrument in combination with an implant wherein the delivery instrument releasably holds the implant in a first configuration prior to attachment of the implant to bone. The delivery instrument allows the implant to be affixed to bone before the implant is released from the instrument. And the instrument may comprise guide means for drills, depth gauges, screws, pins, pegs, blades and or drivers which are used or implanted when the implant is releasably attached to the instrument. After the implant is affixed to bone and released from the delivery instrument, the implant assumes at least a second configuration which provides compression and or distraction and or control of spatial orientation.
