The Single Use Circular Staplers places a circular, double staggered row of titanium staples when it is activated. Immediately after staple formation, the circular knife blade resects the excess tissue and creates a circular anastomosis. The circular stapler uses is very wide.

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.

③The circular stapler uses should not be used if the instrument is too large for the diameter of the structure, which could be stretched or thinned out by introducing the instrument. Failure to that leakage and narrowing of the anastomosis could occur.

④Do not use the Single Use Circular Stapler unless sufficient tissue presents and allows proper inversion of tissue edges, so that staples may be placed securely.

⑤Do not use the disposable circular stapler unless adequacy of hemostasis can be visually verified after firing.
