1.  Exceptional hemostatic effect;

2.  The special design of the outer ring prevents anastomotic tissue from excessive squeezing;

3.  48three-row titanium screws around can effectively close the tissue;

4.  A greater lumen of the staple cartridge can hold more diseased tissue;

5.  Stainless steel anvil and stainless-steel guide shaft to make the closing and firing more stable;

6.  two symmetrical sutures help the tissue to enter into the equipment;

7.  The sharp circular knife can effectively cut;

8.  0.75mm suture clearance compress the mucosa of the best hemostatic effect;

9.  Fool-firing position;

10.  Improved B-type staple make the anastomotic a higher tensile strength.
