When sewing the wound in figure 8, a silk thread with the length of 10 cm prepared in advance is clamped at the horizontal line of the perineal wound, and the silk thread is knotted after sewing. When removing the thread, just cut the real knot at the lower end, lift the silk thread and pull it gently, and the thread will be removed.
Suture refers to the application of suture materials to repair or close wounds, incisions or re-establish channels, so that tissues can gather together and promote healing.
