Push and Twist Mechanism for Interfacing IOL Cartridge with Handpiece

The handpiece and cartridge are designed with a universal interface mechanism that allows the same attachment system to work across different handpiece and cartridge configurations. The standardized interface includes complementary geometric features (protrusions and recesses) that enable interchangeable attachment while maintaining functional compatibility across multiple device variants.

The interface mechanism employs nested geometric features where protrusions on one component fit into recesses on the mating component. This nesting arrangement creates a hierarchical structure of interlocking elements that provide both attachment security and ease of engagement through simple linear motion followed by rotational locking.

The locking mechanism transitions from a static locked state to a dynamic unlocking state through rotational motion. The geometric features are designed to lock securely in the engaged position while allowing controlled detachment through a simple rotational movement, providing both security and ease of operation through dynamic state change.

The attachment and detachment process follows a periodic cycle: linear insertion, rotational locking, secure holding, rotational unlocking, and linear removal. This periodic action pattern ensures reliable attachment during surgery while enabling quick detachment when needed, with each phase of the cycle serving a specific functional purpose.
