PHACOEMULSIFICATION NEEDLE WITH IMPROVED SAFETY AND MANUFACTURABILITY

摘要

An ultrasonic phacoemulsification needle with improved safety and manufacturability, comprising: a metal connection body and a plastic needle in a splitting structure. The plastic needle is connected at the distal end of the metal connection body, and the metal connection body is connected to the distal end of an ultrasonic hand piece. The ultrasonic phacoemulsification needle employing a design of splitting the connection body and the needle alleviates the difficulties for manufacturing otherwise caused by the conventional phaco tip designs. It reduces the surgical costs from patients. In addition, the ultrasonic phacoemulsification needle using a plastic body reduces the likeliness of punctuating the capsule bag, which otherwise easily occurs in the metal needle case due to the extremely sharp rigid tip at the end of the needle, thus the risks of surgery are reduced and safety is improved.
