Clip applier configured to prevent clip fallout

A surgical clip applier, comprising:

• a shaft;
• jaws formed on a distal end of the shaft;
• a jaw closing mechanism extending through the shaft and coupled to the jaws;
• a preloaded joint associated with the jaw closing mechanism and being advanceable distally during a closing stroke, the preloaded joint being configured to prevent a clip from falling out of the jaws when a force applied to close the jaws is at least partially released during the closing stroke, and the preloaded joint including a biasing element disposed in a recess that includes at least one ridge formed therein configured to maintain the biasing element at a substantially constant load during a closing stroke and up through full closure of the jaws.

A surgical clip applier, comprising:

• a shaft;
• first and second jaws formed on a distal end of the shaft;
• and
• an assembly coupled to the jaws and adapted to prevent clip fallout when a force applied to close the jaws is at least partially released during a closing stroke, the assembly including a recess and a biasing element formed in the recess, the recess including at least one ridge configured to prevent the biasing element from deflecting under compression during final stages of a closing stroke.
