ABSTRACT:
A semi-automated machine 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 needle singulation station, a precise positioning station, a suture feeding station, a swage station, a pull-test station and an off-load station. 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 opening about the suture to secure said suture thereto and form therefrom a needle and suture assembly. An off-load station provides an apparatus for assembling a predetermined number of need-suture assemblies in a bundle for subsequent packaging. The bundles are collected in a plurality of buckets that are circumferentially arranged on a rotating table. A needle stripping device ensures discharge of the needle suture assembly into the bucket.
