Operation method of the staples used in surgery: An intestinal anastomosis is used to illustrate the use of the stapler. The anastomosis is sutured in the proximal intestine, placed in the staple holder and tightened. The stapler is inserted from the distal end, the central piercer of the stapler is threaded out and articulated with the central rod of the proximal stapler against the staple holder, and rotated close to the distal and proximal bowel walls. Adjust the distance between the staple holder and the base according to the thickness of the intestinal wall, generally by turning the hand tighter (with a tightness indicator pin on the handle).
Squeeze the closing anastomosis wrench to tighten the anastomosis, and the sound of the sound indicates that the cutting anastomosis is complete. Do not withdraw the anastomosis and check to see if the anastomosis is satisfactory and if other tissues, such as the mesentery, are embedded. After being dealt with accordingly, the anastomosis was unscrewed and gently pulled from the distal end to check for the integrity of the distal and proximal bowel resection rings.
Precautions for use of the stapler
(1) Before the operation, check whether the ruler and 0 scales are aligned, whether the assembly is correct, and whether the push-piece and tantalum nail are missing. A plastic washer should be installed in the resistor.
(2) The broken end of the intestine to be anastomosed should be fully free and stripped at least 2cm.
(3) The distance between the stitches of the purse suture should not exceed 0.5cm, and the margin should be 2~3mm so that too much tissue is easy to embed in the anastomosis and hinder the anastomosis. Be careful not to omit the mucosa.
(4) Adjust the spacing according to the thickness of the intestinal wall, with 1 to 2 cm being appropriate.
(5) Check the stomach, esophagus, and other adjacent tissues before hitting to prevent clamping into the anastomosis.
(6) The cut should be made quickly, and pressure should be applied at the end to make the staple into a "B" shape.
(7) Exit the surgical stapler gently and check whether the incised tissue is a complete ring.
