When using sutures for surgery, depending on the fragility of body tissues, organs and blood vessels, the sharpness of the needle tip and the size of the needle eye must be taken into account to avoid tissue trauma; depending on the depth of the organ parts, pay attention to the needle when selecting The angle of the bend. The triangular needle is easy to tear the tissue when it passes through the tissue, so it is often used in tough connective tissue and skin. There are many types of needles used now,
