Disposable Interspinous Stabilization Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for implanting interspinous / interlaminar stabilization devices require precise sizing and adjustment, which can be challenging and may involve reusable instruments that pose infection risks due to resterilization needs.
Innovation Solution
Disposable surgical instruments with dual-functioning heads for measuring and attaching the devices, allowing for precise sizing and secure implantation without the need for resterilization, including a handle component and head component that can be easily attached and detached for single-patient use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reusable instruments are used for implanting stabilization devices, then instrument durability and cost-effectiveness are improved, but infection risk increases due to resterilization requirements
Solution Approach 1:
The patent employs disposable surgical instruments for implanting stabilization devices, eliminating the need for resterilization and associated infection risks. The instruments are designed as single-use items that are discarded after one patient procedure, ensuring sterility while maintaining cost-effectiveness through efficient design and material selection.
2Manufacturing precision
If precise sizing and adjustment are performed during implantation, then device fit and stability are improved, but procedural complexity and time requirements increase
Solution Approach 1:
The patent incorporates pre-marked measurement indicators and pre-configured sizing features on the stabilization devices and accompanying instruments. These preliminary markings allow surgeons to quickly determine the correct device size and make necessary adjustments without complex measurement procedures, reducing both procedural complexity and time requirements while maintaining precise sizing accuracy.
3Object-affected harmful factors
If disposable instruments are used for single-patient procedures, then infection risk from resterilization is reduced, but logistical costs and waste increase
Solution Approach 1:
The patent designs disposable instruments using cost-effective materials and streamlined manufacturing processes that minimize production costs. By making the instruments affordable as single-use items, the system eliminates expensive resterilization logistics and associated infection risks, while the low per-unit cost reduces the impact of disposal waste.
4Productivity
If instruments with dual-functioning heads are used for measuring and attaching devices, then instrument versatility and efficiency are improved, but instrument design complexity increases
Solution Approach 1:
The patent employs instruments with dual-functioning heads that can perform both measurement and attachment operations. One head configuration is optimized for measuring anatomical landmarks and device positioning, while the other head is designed for securing the stabilization device to bone. This multi-functionality consolidates multiple tools into one instrument, improving implantation efficiency despite the increased design complexity, which is managed through modular construction and standardized components.

AI summary
Surgical instruments to properly implant interspinous / interlaminar stabilization devices, and instrumentation kits containing these instruments are provided. These surgical instruments may be configured to be disposable, or for single patient use, and therefore do not require resterilization for reuse, thus reducing risk of infection as a result of reuse and logistical costs associated with these resterilization procedures.
