Abstract

A semi-automated machine and method for singulating individual surgical needles from an bulk supply and attaching a suture to the surgical needle is described. Each of the surgical needles has a suture receiving opening formed therein for receiving a suture. The machine includes a singulation station having a sliding surface that assists an operator in singulating needles and depositing them in a pair of drop locations for subsequent automatic handling. Indexing conveyors, an articulated robot and a precision conveyor are used with a precise positioning station for orienting each needle for automatic handling. A universal gripper mounted on a rotary indexing device automatically receives each individual needle in a predetermined orientation and conveys the needle for sequential processing from station to station to form the needle-suture assembly. A suture feeding and cutting station automatically cuts an indefinite length of suture material to a definite length suture strand and automatically inserts an end of the definite length suture strand into the suture receiving opening formed in the needle. A swage station is provided for swaging the needle to close the suture receiving op…
