Intraocular Lens Injector With Auto-Activated Haptic Folding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injectors for intraocular lenses require complex manual operations to fold and apply the haptics, which can be cumbersome and inefficient during surgical procedures.
Innovation Solution
The injector system includes a haptic slider that is automatically activated upon magazine attachment, simplifying the folding process by ensuring the haptic elements are folded before the lens is applied, with sliding elements that move in a coordinated manner to facilitate easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the haptic slider is manually activated separately, then the folding process can be controlled, but the operation becomes complex and time-consuming
Solution Approach 1:
The magazine is pre-configured with the haptic slider positioned to automatically fold the haptic element when attached to the injector. This preliminary arrangement eliminates the need for separate manual activation steps during surgery, reducing operational complexity and time loss.
Solution Approach 2:
The system is designed so that the act of attaching the magazine to the injector automatically triggers the haptic folding action through the haptic slider. The system performs the folding function autonomously during the attachment process, eliminating the need for additional manual intervention.
2Reliability
If the haptic element is folded manually before lens application, then proper positioning is achieved, but the procedure becomes cumbersome
Solution Approach 1:
The haptic folding function is merged with the magazine attachment process. The haptic slider is integrated into the magazine structure, and its activation is combined with the mechanical action of attaching the magazine to the injector, thereby simplifying the overall procedure while ensuring reliable haptic folding.
Solution Approach 2:
The haptic slider acts as an intermediary mechanism that translates the mechanical action of magazine attachment into the specific motion required for haptic folding. This intermediary component ensures reliable haptic positioning without requiring complex manual manipulation.
3Manufacturing precision
If multiple separate steps are used for haptic folding and lens application, then each step can be controlled precisely, but the overall process becomes inefficient
Solution Approach 1:
The haptic slider is pre-positioned in the magazine to ensure precise folding action occurs automatically during attachment. This preliminary configuration maintains folding precision while eliminating the need for separate controlled steps, thereby improving surgical efficiency.

AI summary
The invention relates to an injector (1) for intraocular lenses (2). The injector may comprise an automatically activatable haptic slider (31a, 31b). The injector (1) can be designed such that a folding element (13) for folding the intraocular lens (2) is disabled when the haptic slider (31a, 31b) is not activated. The invention further relates to a system comprising a container in which an intraocular lens (2) is stored in a magazine (30). When the magazine (30) is received by the injector housing (10), the haptic slider (31a, 31b) is automatically activated.
