Medical suture needles are mainly used for suturing tissues and transfixtion ligation, and are required to be made of high-quality and high-toughness stainless steel.

① Its strength should ensure that they can carry the suture through the tissue with minimal resistance and the drag of the tissue is minimized;

② Its toughness should ensure that they tend to bend before breaking, so that the operator can feel this signal in advance in order to take timely measures;

③ Its structural design should ensure the stability and reliability during operation, so that doctors can operate more smoothly and at ease.
