The disposable curved cutter stapler is an instrument capable of hitting four rows of stapler staples staggered in a curved line, as well as an instrument capable of cutting off tissue. It has good cutting and suturing abilities.

It is applicable to mutilation, excision and suture in the operation of alimentary canal such as stomach and intestines.

1. The tissue has inflammation, edema or tumor.

2. The tissue is so thick (two layers of gastrointestinal wall, when compressed, is estimated to be more than 2.5~3mm) that the stapler cannot penetrate it.

3. The tissue is so thin that putting in the stapler may tear it.

4. In principle, it is inappropriate for mechanical suturing again if the first one fails.
