A method of thermal forming of refractory alloy suture needles is disclosed. Needle blanks made from refractory alloys are used to form surgical needles, which are heated to a temperature above the ductile to brittle transition temperature but below the recrystallization temperature of the refractory alloy. The heated needle blanks are then mechanically formed into a surgical needle. A Fixture (300) and an apparatus (500) for forming refractory alloy surgical needles using this method are also disclosed.
La présente invention concerne un procédé de thermoformage d'aiguilles de suture en alliage réfractaire. Des ébauches d'aiguilles en alliages réfractaires sont utilisées pour former des aiguilles chirurgicales qui sont chauffées à une température supérieure à la température de transition de l'état ductile à l'état cassant, tout en restant inférieure à la température de recristallisation de l'alliage réfractaire. Les ébauches d'aiguilles chauffées servent ensuite à former mécaniquement les aiguilles chirurgicales. L'invention porte aussi sur un dispositif de fixation (300) et un appareil (500) permettant de former les aiguilles chirurgicales en alliage réfractaire à l'aide de ce procédé.
