Pre Advanced Disposable Circular Stapler

Scope of Application

It is used for end-to-end, end-to-side and side-to-side anastomoses of the digestive tract in reconstruction of digestive tract such as esophagus, stomach and intestine

Usage

1. Before use, make sure the red safety button is closed, take off the blue protective cover, and check that there should be no missing titanium nails in the staple bin.

2. Place the stapler nail holder and the body into both ends of the organ tissue to be anastomosed, and make a purse suture around the nail holder circlip tube and the organ tissue at both ends of the body guide shaft respectively and tie them tightly;

3. In the end-end anastomosis and end-side anastomosis, for the convenience of making a purse, you can use the purse extension rod.

Insert the purse extension rod into the nail holder circlip tube, then put the nail holder into the tissue on the side to be anastomosed, make a purse suture around the circlip tube and tie it tightly, and then take out the purse extension rod by clamping the circlip tube with forceps.

4. Insert the nail holder into the body guide shaft, and a clear sound can be heard at this time. Then, rotate the adjusting nut clockwise to make the two broken ends of the anastomotic tissue close together and press tightly, ensuring that there is no excess tissue in the nail holder and the staple bin, and the indicator needle has entered the green area in the window. Determine the firing position according to the thickness of the tissue.

5. Confirm that the tissue that has been anastomosed at both ends has been inserted into the cavity of the nail holder and the body, open the red safety button, firmly grip the handle, and fire at once. At this time, a clear "click" sound can be heard, indicating that the firing has been completed, and keep a firm grip on the handle for 30 ~ 60 seconds.

6. Rotate the adjusting nut counterclockwise for 2～3 turns, then gently shake the instrument from side to side and slowly exit outward.

7. Unplug the nail holder and check the annular integrity of the cut tissue. If any incompleteness is found, several stitches must be added in the corresponding site.

Precautions

1. When using this product, aseptic operation specifications should be strictly followed;

2. Please read the instructions carefully before use;

3. This product is intended for use by physicians who have been trained in the expertise and techniques of stapler or under the guidance of a physician with relevant experience;

4. The product is limited to single-use and is sterilized by irradiation with a validity period of two years. It is strictly prohibited to use if the inner packaging is damaged or expired;

5. The product is prohibited from secondary sterilization;

6. After removing the stapler nail holder and the protective cover, the anastomotic staple in the staple bin should be visible under the light, and it is prohibited to use if there is a missing staple;

7. Before making the purse, clean the inner and outer walls of the anastomosis of the tissue to be anastomosed and remove them;

8. When making a purse, the purse line should be as perpendicular to the tissue axis as possible, so that the circumference of the purse line is the shortest and the excess tissue on the outside of the purse is removed, leaving only 2~3mm;

9. The adjusting nut should not be tightened too much, and in general, it is appropriate to indicate at 2 mm in the window (except for end-to-end rectal anastomosis and small bowel surgery);

10. Please note that during anastomosis surgery, the handle can only be held tightly once and must be firmly held to the end, and the safety button should be dialed up immediately after releasing the hand to avoid the secondary cutting misoperation;

11. End-to-side anastomosis is recommended for rectal surgery;

12. According to the size of the anastomosis, choose the anastomotic staples. If the stapler is not selected properly, the anastomosis nail can not meet the requirements of forming or can not be formed, the anastomosis is difficult to achieve success;

13. Please destroy it as required after use;

14. The instructions cannot be used as the basis for the guidance of clinical surgical anastomosis. Please refer to the professional literature or consult the company and its designated agents for the guidance on clinical surgical anastomosis techniques.

Contraindications

1. The use of anastomoses is not advisable if the esophageal mucosa is edematous, the muscular layer is thickened and the healing capacity is poor.

2. If the esophagus is too thin or the muscular layer of the tube wall is too thin, it is easy to tear the tube wall when the nail holder is placed;

3. If the first mechanical anastomosis fails, in principle, a second anastomosis is not advisable, because the esophageal cut edge is neat, and the tissue is severely compressed by the machinery, the blood supply is poor, the stomach wall mouth has been enlarged, so that it is difficult to obtain success with another anastomosis.

4. Mechanical anastomosis is also not advisable in cases where cancerous tissue is suspected to remain in the esophageal cut or where the esophageal muscle layer is damaged.
