发明名称 SURGICAL NEEDLE MANUFACTURING PROCESS
摘要 A process for manufacturing a surgical needle incorporates at least one pressing operation which, preferably, in conjunction with a trimming and/or etching process, ultimately forms the sharpened needle end. The grinding operation i n the preferred process does not produce the primary sharpened edges of the needle , but, rather is incorporated, in one instance, to reduce excess needle material prior to the pressing operation. Consequently, the amount of flash material generated during pressing is substantially reduced. This feature desirably enhances the subsequent trimmi ng and etching operations, and produces a needle which is extremely sharp, durable and exhibits an improved retention of sharpness over periods of prolonged use.
