Adjustable Compression Staple and Method for Stapling With Adjustable Compression

摘要

A method for applying and maintaining compression with a staple includes piercing a material with deformable ends of staple legs. The legs enter the material until the material applies a pre-set compressive force within a pre-defined compression range to a compression device disposed at least partly between the legs. The compression device has a compression resistor connected to a compression surface. The compression surface is movably disposed with respect to the bridge. Movement of the compression surface towards the bridge is resisted with a force imparted by the compression resistor. The legs are deformed to maintain at least some of the compressive force between the material and the compression device. Forces greater than the pre-set force are absorbed with the compression resistor. The pre-set compressive force to the material is maintained within the pre-defined compression range throughout a state change of the material.
