摘要: An improved ophthalmic needle and method for manufacturing the same for use with an ophthalmic instrument for extracapsular removal of a cataract. The needle comprises a coaxial tube portion, a separated tube portion, and a tank portion, interposed therebetween for flow conversion purposes. A metal-to-metal seal is effectuated between tubes at the coaxial portion by a spinning method employing a forming die in conjunction with a lathe. A unique use of fixtures is employed to properly orient the various tubes with respect to the tank and to effectuate joint sealing.
