Pointed Ocular Implant Inserter for Secure Sub-Conjunctival Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical devices for implantation in the eye, such as intraocular lens injectors, require a blunt tip for corneal incision, which is stressful for patients and can lead to dislocation due to variability in the placement process, especially during sub-conjunctival insertion.
Innovation Solution
An implantation device with a pointed tip and a conical-cylindrical design that integrates with standard IOL delivery systems, allowing precise insertion of medical devices into the eye, minimizing discomfort and ensuring secure placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a blunt tip is used for corneal incision, then the device can be integrated with standard IOL delivery systems, but the procedure becomes stressful for patients and may lead to dislocation due to placement variability
Solution Approach 1:
The device applies local quality by having different tip geometries for different functions: a blunt tip for the initial corneal incision (compatible with standard systems) and a pointed tip for precise sub-conjunctival insertion (reducing dislocation risk). This resolves the contradiction by optimizing each local interaction point for its specific purpose.
Solution Approach 2:
The delivery device is segmented into multiple functional components with distinct tip characteristics. The system divides the insertion process into stages: initial penetration with a blunt tip, followed by precise placement with a pointed tip. This segmentation allows each component to specialize in reducing specific harmful effects.
2Object-affected harmful factors
If a pointed tip is used for precise insertion, then patient comfort and placement security improve, but the device cannot be integrated with standard IOL delivery systems
Solution Approach 1:
The invention merges two previously separate delivery approaches into a single integrated device. The blunt tip section maintains compatibility with standard IOL delivery systems, while the pointed tip section provides precise sub-conjunctival insertion. This combination resolves the contradiction by unifying both functional requirements in one device.
Solution Approach 2:
The delivery device achieves multi-functionality by incorporating both blunt and pointed tip capabilities. It can perform both the initial corneal incision (blunt tip function) and the precise sub-conjunctival insertion (pointed tip function), making it universally applicable to both standard IOL delivery systems and precise implantation requirements.
3Reliability
If sub-conjunctival placement requires carving a pocket with separation of conjunctiva, then the insert can be positioned, but the procedure becomes complex and may result in loose placement requiring closure of snip
Solution Approach 1:
The device performs preliminary action by creating a pre-formed pathway through the conjunctiva with the pointed tip before insert deployment. This eliminates the need for post-insertion adjustments or closure procedures, as the pathway is precisely created in advance to accommodate the insert securely.
Solution Approach 2:
The invention extracts the complex pocket-carving procedure from the implantation process. Instead of requiring separation of conjunctiva and formation of a pocket space, the pointed tip directly creates a precise insertion channel, simplifying the overall procedure while maintaining reliable insert placement.
