Ligature needles refer to instruments for joining fabrics. They, like ordinary needles, contain an eyelet for inserting a thread and have a special semi-circular darling, which is exactly allowed to sew fabrics in the transverse direction of rounded tissues (stomach, intestines, etc.) They are divided into two types:
1 - a blunt ligature needle - Deschamps needle - used in tissues with a soft texture of a pierced organ;
2 - a sharp ligature needle - Cooper's needle allows to sew in a semicircle not only internal organs, but also connective tissue and skin.
