1. Before the operation of the disposable stapler, check whether the scale is aligned with the 0 scale, whether the assembly is correct, and whether the push piece and the tantalum nail are missing. Install a plastic washer inside the needle seat.

2. The broken end of the intestinal tube to be anastomosed should be fully free and stripped at least 2 cm.

3. The purse stitch length is not more than 0.5 cm and the margin is 2 to 3 mm. Too much tissue is easily embedded in the anastomosis and hinders the anastomosis. Be careful not to miss the mucosa.

4. Adjust the spacing according to the thickness of the intestinal wall, preferably 1 to 2 cm.

5. Check the stomach, esophagus and other adjacent tissues before firing to prevent pinching into the anastomosis.

6. Stapler should be cut fast, pressurized at the end to make the staple into "B" type, and strive for a success, if you think it is not accurate, you can re-cut.

7. Withdraw the stapler gently, and check whether the cut tissue is a complete ring.
