Types of circular staples: laparoscopic circular stapler, eea 31 stapler, etc.

①Do not use the Single Use Circular Stapler on any tissue that will be compressed to less than 1mm in thickness as the staples will not be tight enough to ensure hemostasis.

②Do not use the disposable circular stapler on any tissue which cannot be compressed comfortably to 2.0mm for 21 mm and 23mm, 2.3mm for 25mm and 27mm, 2.5mm for 29mm, 31 mm and 33mm in thickness. Overly thick inverted tissue could be crushed when the instrument is closed. Failure to do it may result in poor heeding, or narrowing of the anastomosis.
