The cutting needle of the surgical suture needle, because its needle body has edges, it is easier to penetrate the tough tissues such as the skin. However, the cutting needle tip has a greater damage to the tissue, so the cutting needle of the surgical suture is generally not used to suture the connective tissuee and blood vessels.

Because of its smooth body and little damage to tissues, the round needle is used to sew the soft tissues such as subcutaneous soft tissues, connective tissues, viscera and blood vessels. However, this kind of needle is not easy to penetrate tough tissues such as skin, so it is generally not used to sew skin.

According to the length and radian of the needle, the cutting needle and round needle of the surgical suture needle can be divided into different types, and they are properly selected in different tissues and different parts.
