V. Instructions for Operation
1. Take the instrument out of the package in the sterile purifying area. To avoid any damage, the instrument shall be handled gently.
2. Open the free handle cover, separate the cutter assembly from the anvil, and then remove the cartridge cover.
3. Clamp the tissue to be cut and sutured between the cartridge and the anvil support, and then press the free handle cover to the locking position (Note: The free handle cover must be pressed to its place).
4. Hold the cutter stapler in one hand and push the ejector pad with the thumb and forefinger of the other hand to the firing position (as the cutting knife still does not start cutting, the hand feel is light), and then continue pushing the ejector pad uniformly forwards to the front end (the hand feel is heavy, indicating that the cutting knife starts cutting the tissue and suturing the tissue at both sides).
5. Reset the ejector pad (there is red indication on the instrument, as shown in figure 1). Pay attention that the stapler cannot be lifted immediately. The free handle cover must be first released and the cartridge and anvil support shall be separated; after that, the instrument shall be removed, and then the operation is completed.
