1.  The green one of indicator can easily show the thickness of tissue to be cut and anastomosed; 

2.  Reasonable number of staples conduce to reduce the postoperative bleeding; 

3.  Imported titanium staples with higher intensity and tenility; 

4.  Integral shaping anvil to ensure the shape of staples; 

5.  Large diameter ratio, avoids anastomotic stenosis effectively; 

6.  Minimum gap between anvil and cartridge to avoid the damage to tissue caused by over pressure; 

7.  Streamline design is accordant with the human engineering, with as a comfortable powerful operation feel.
