Intraocular Lens Interface Bracket for Secure Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intraocular lens (IOL) surgery systems face challenges in securely handling and positioning the small IOL interface, which can be difficult to grasp manually, especially during surgical procedures, and often require separate assembly devices, leading to potential loss and increased complexity.
Innovation Solution
An IOL insertion system comprising an IOL insertion cartridge with a detachable bracket that secures the IOL interface via friction, featuring protuberances and a detent mechanism to stabilize and prevent accidental advancement, allowing for easier handling and engagement with surgical tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the IOL interface is made small for precise positioning, then positioning precision is improved, but ease of manual handling deteriorates
Solution Approach 1:
The system is divided into distinct components: a small IOL interface for precise positioning and a larger IOL insertion cartridge for easy handling. The interface can be separately loaded into the cartridge, allowing each component to optimize its size for its specific function.
Solution Approach 2:
The IOL insertion cartridge acts as an intermediary between the small IOL interface and the surgeon's hand. The cartridge provides a larger grip surface while maintaining precise control over the small interface through its structured design with wings and engagement features.
2Measurement precision
If the IOL interface is made small, then positioning precision is improved, but risk of loss increases
Solution Approach 1:
The small IOL interface is nested within the larger IOL insertion cartridge. The interface fits into a receptacle or cavity within the cartridge body, ensuring it remains contained and secured during storage, preparation, and insertion procedures.
Solution Approach 2:
The IOL interface and IOL insertion cartridge are combined into a single integrated assembly. The interface is securely attached to the cartridge through friction fit, mechanical interlocking, or adhesive bonding, ensuring they move together as one unit and eliminating the risk of the small interface being lost.
3Stability of the object's composition
If a detachable bracket is added to secure the IOL interface, then stability is improved, but device complexity increases
Solution Approach 1:
The bracket is designed as a detachable component that can be removed after the IOL interface is secured to the cartridge. This allows the bracket to provide temporary stability during assembly and insertion, then be discarded or reused, avoiding permanent complexity in the final system.
Solution Approach 2:
The bracket transitions from a static securing mechanism to a dynamic, detachable component. It is engaged during assembly to provide stability, then detached after the IOL interface is securely attached to the cartridge, allowing the system to evolve from a complex assembly state to a simpler final state.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures stable positioning and secure handling of the IOL interface, reducing the risk of loss and simplifying the surgical process by integrating the interface with the larger cartridge, facilitating intuitive engagement with insertion tools and eliminating the need for additional assembly devices.
Implementation Method 1
The cavity is sized to hold the IOL interface in place by friction between the IOL interface and the bracket and the IOL insertion cartridge
Implementation Method 2
the detent may be used for storing energy in the IOL interface to aid in removing it from the system

AI summary
Various systems, apparatuses, and processes may be used for intraocular lens surgery. In particular implementations, a system for intraocular lens surgery may include an intraocular lens insertion cartridge and an intraocular lens interface adapted to engage an intraocular lens for advancement through the intraocular lens insertion cartridge. The system may also include a bracket that is detachably attached to the intraocular lens insertion cartridge and that facilitates securing the intraocular lens interface relative to the intraocular lens insertion cartridge.
