Title
(EN) POST LASER DRILLING STRESS RELIEF OF SURGICAL NEEDLES MADE OF REFRACTORY ALLOYS
(FR) RELAXATION DE CONTRAINTE POST-FORAGE LASER D'AIGUILLES CHIRURGICALES RÉALISÉES EN ALLIAGES RÉFRACTAIRES
Abstract
(EN) A method of stress relieving drilled surgical needles is disclosed. At least the metal about a drilled bore hole is heat treated to relieve stress without annealing.
(FR) L'invention porte sur un procédé de relaxation de contrainte d'aiguilles chirurgicales percées. Au moins le métal autour d'un trou d'alésage percé est traité thermiquement pour relaxer les contraintes sans recuit.
