Adjustable compression staple and method for stapling with adjustable compression
First Claim
Patent Images
1. A compression-self-adjusting staple, comprising:
- a substantially U-shaped staple body having;
a bridge; and
two legs extending from said bridge at an angle thereto, each of said legs having;
a base end integral with said bridge; and
a deformable distal end defining a stapling point shaped to pierce material to be stapled;
a compression device;
at least partly disposed between said legs; and
having a bias portion with;
a compression surface movably disposed between said legs; and
a compression resistor;
connected to said bridge and to said compression surface; and
being formed to resist movement of said compression surface towards said bridge with a pre-set compressive force that ensures stapling within an optimal tissue compression range upon application of a stapling force and, after stapling, maintains the pre-set compressive force within the optimal tissue compression range; and
having a variation in cross-section including at least one of a variation in cross-section shape and a variation in cross-section thickness.

Abstract
A compression-self-adjusting staple includes a substantially U-shaped staple body and a compression device. The staple body has a bridge and two legs extending from the bridge at an angle thereto. Each of the legs has a base end integral with the bridge and a deformable distal end defining a stapling point shaped to pierce material to be stapled. The compression device is at least partly disposed between the legs and has a bias portion with a compression surface movably disposed between the legs and a compression resistor connected to the bridge and to the compression surface and formed to resist movement of the compression surface towards the bridge with a force.
