Single-use Implant Deployment System with Preloaded Spring Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spinal surgery devices for procedures like vertebroplasty and kyphoplasty require significant force for deployment, and the reusable instrumentation is costly and time-consuming to clean and sterilize, with limited ability to mechanically deform and restore vertebral body height.
Innovation Solution
An implant deployment system featuring an actuation rod driven by an energy storage container, which releases energy to expand or compress an implant upon insertion, using a preloaded energy source such as a compressed spring or pressurized metal bellows, allowing for controlled deployment with reduced material costs and simplified assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional reusable instrumentation is used for implant deployment, then the deployment can be performed, but the cleaning and sterilization requires additional effort and time and is costly over long periods
Solution Approach 1:
The patent describes a single-use implant delivery system that eliminates the need for reusable instrumentation requiring sterilization. The entire delivery system including inserter, actuator, and implant is provided as a pre-sterilized disposable unit, thereby eliminating cleaning and sterilization time and costs while maintaining deployment functionality
2Ease of operation
If considerable force is applied to deploy traditional devices, then the implant can be deployed, but the instrumentation requires considerable amounts of force and complex mechanisms
Solution Approach 1:
The patent employs a pre-loaded spring mechanism that is compressed during implant loading and automatically releases during deployment. This preliminary action stores mechanical energy that is then released to drive the expansion and deployment of the implant, eliminating the need for the operator to apply considerable force during the actual deployment procedure
Solution Approach 2:
The implant delivery system is designed to be self-actuating through the pre-loaded spring mechanism. Once the implant is positioned, the operator simply releases the locking mechanism and the stored spring energy automatically drives the deployment process, making the system self-service and eliminating complex manual actuation mechanisms
