EEA ANVIL SNAP RING ACTIVATOR

摘要

A surgical fastening apparatus and associated method of use is disclosed. The surgical fastening apparatus includes a handle assembly, a central body portion extending from the handle assembly, and a distal head portion including an anvil head assembly. The anvil head assembly includes an anvil head defining an interior recess, an activator plate, a deformable member, and a securing member. The anvil center rod assembly defines a longitudinal axis and is pivotably connected to the anvil head assembly about a pivot axis. The anvil center rod assembly includes a configured to contact the anvil head assembly upon an actuation of the surgical fastening apparatus. Upon the actuation of the surgical fastening apparatus, the deformable member is configured to deform such that the activator plate is advanced distally into the interior recess to facilitate the anvil head pivoting about the pivot axis.

主权项

1. An anvil assembly for use with a surgical fastener apparatus having a handle configured to move through at least one firing stroke to deliver fasteners, the anvil assembly comprising:
an anvil center rod configured for coupling with the surgical fastener apparatus and defining a longitudinal axis; an anvil head mounted to the anvil center rod, the anvil head configured for pivotal movement relative to the anvil center rod between an initial condition and a pivoted condition; an activation portion configured to engage the anvil head to secure the anvil head in the initial condition, the activation portion configured for longitudinal movement from an initial position to an advanced position upon movement of the handle through the at least one firing stroke to release the anvil head to permit pivotal movement to the pivoted condition; a deformable portion supported with the anvil head adjacent the activation portion, the deformable portion configured to deform during the at least at least one firing stroke to permit longitudinal movement of the activation portion to the advanced position; and a securing portion configured to secure the activation portion in the advanced position.
