Process for manufacturing drilled taper point surgical needles |
摘要 |
A process for manufacturing wire or needles having a taper point and mechanically drilled suture mounting holes in the proximal ends. Needle or wire blanks are cut from a roll of wire and mounted to a carrier strip. The carrier strip and needles are moved through a succession of forming and trimming and grinding stations. The blanks are coined in a coining die to produce lateral wings of constant thickness. The blanks are preferably rotated in the strip while being ground. The strip and needle blanks are then moved to a bank of at least two drills wherein the proximal suture mounting ends of the needles are drilled.
