A method for manufacturing a surgical needle produced from a wire made of a hyperelastic or superelastic alloy including a Ni—Ti alloy base includes:
carrying out a cold shaping or a shaping at ambient temperature of the curved profile of the needle in an appropriate support;subjecting the needle in its support to a thermal treatment in order to memorize the imposed curved-profile geometry;cleaning the needle via a chemical stripping of the electrochemical or electrolytic polishing type or via a chemical solution in order to remove the layer of oxide deposited on the needle during its thermal treatment. |
