Surgical Needles Design

Key factors in the surgical needle basic design include the quality of its alloy, surface coating, and needle geometry. While the needle alloy defines needle bending strength and ductility, the silicon coating maintains the sharpness and consistency of needle penetration. The design of needle tips is also based on the type of tissue where they will be used1


How are Peters Surgical needles made?  

Peters Surgical needles are made from 300 series austenitic stainless steel, providing better bending resistance and ductility compared to 400 series alloy needles available on the market2. Our needles come in multiple configurations to meet the specific needs of your procedure.
