THERMAL FORMING OF REFRACTORY ALLOY SURGICAL NEEDLES AND FIXTURE AND APPARATUS
摘要
<p>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.</p>
