I. Product name, model, specification of arc cutting stapler
Table 1 The basic dimensions of a disposable arc stapler Unit: mm
| Model and specification | Suture length L1 | Tolerance | Cutting length | Tolerance | Staple height | Tolerance |
| PHX-A-45 | 45 | ±2 | 40 | ±2 | 4.8 | ±0.2 |

II. Arc cutting stapler performance:
The single-use arc stapler should be able to be assembled and disassembled smoothly; each moving part should be easily pushed, and there should be no jams or looseness; the nail seat and components should be firm after being installed, and the nail tip in the nail bin should face outward There must be no lack of nails. The staples should not fall off after being shaken. The staple heads should be sharp. The arc-shaped cutting stapler should have good anastomosis and cutting performance. The staples after the anastomosis should be B-shaped, and the cutting edge after each anastomosis It should be neat and free of burrs. The length of the anastomotic line is at least 1.5 times longer than the length of the cutting line. The nail length should be flexible and safe to use. The spring should have enough elasticity to be quickly reset when the handle is released. The suture opening of the disposable arc stapler after suture should be able to withstand a pressure of no less than 36kPa, and there should be no water leakage or tearing.
III. Main structure of arc cutting stapler:
The PHX-A-45 type disposable arc stapler is mainly composed of a staple seat, a staple cartridge, a component splint, a positioning pin, a positioning button, a reset button, a fixed handle, a movable handle, a cutting knife and suture staples, and other components.
The PHX-B-40 type disposable arc stapler is mainly composed of a staple seat, a staple cartridge, a component splint, a reset button, a fixed handle, a closed handle, a firing handle, a cutter, and staples.

VI. Contraindications of arc cutting stapler:
1. The arc component of 4.8 nails is suitable for tissue thickness of 2.0mm, and it is prohibited to use when the tissue thickness is much larger than the corresponding tissue thickness or much smaller than the corresponding tissue thickness.
2. Prohibited on ischemic or necrotic tissues;
3. It is forbidden on main blood vessels that lack proximal or distal control.
VIII. Instructions for arc cutting stapler use:
How to use the disposable arc stapler (PHX-A-45 type);
1. Take out the stapler from the packaging box in the aseptic area, and place the tissue to be sutured between the staple cartridge and the staple seat according to Figure .
2. Perform a grip action according to Figure to make the movable handle move backwards to about half of the movable range. The movable handle does not reset when the hand is released. At this time, the tissues in the stapler cartridge and the staple seat can be adjusted appropriately. The position between them makes the organization properly placed, and the organization has no overlap. After adjusting the tissue, you can continue the gripping action, so that the movable handle is pressed to the final position, and a "click" can be heard. At this time, the stitched tissue is compressed between the staple cartridge and the staple seat, and the movement is released. The handle and the movable handle automatically return to the open position, as shown in the figure: but the sutured tissue has been clamped by the staple seat and staple cartridge.
3. Do the gripping action again to bring the movable handle to the final position, as shown in Figure (4). At this time, the staples in the staple cartridge are fired, and the tissue is sutured and cut.
4. The movable handle is locked, completing the suture cutting process.
5. Press the reset button, the movable handle will automatically pop up, return the positioning button, and exit the stapler.
