Endoscopic Clip Hook Structure for Secure Re-Grasping

The hook portion is pre-configured with a protrusion that will engage with the engaged portion before the locking operation is completed. This preliminary engagement structure ensures that once the arms are locked, the connection can be easily released by simply pulling the operation wire, as the hook portion is already positioned to disengage. The protrusion is designed to prevent unintended disengagement during the locking process while allowing easy release afterward.

The hook portion is designed with a protrusion at a specific location that creates a localized engagement feature. This protrusion fits into a corresponding recess in the engaged portion, creating a secure connection that prevents accidental disengagement. The local quality of the protrusion design ensures that the connection is secure during re-grasping operations while still allowing intentional release when needed.

The hook portion is segmented into distinct functional features: the main hook body for engagement, and a protrusion feature for preventing unintended disengagement. This segmentation allows each feature to perform its specific function independently. The protrusion is a simple additive feature rather than a complex mechanism, minimizing the increase in device complexity while achieving the desired reliability improvement.
