Methods, systems, and devices for attaching a surgical suture to a surgical needle and testing an installed surgical needle

摘要

A method of attaching a surgical suture to a suture needle and testing the attachment includes dispensing a length of suture from a spool by using a first suture grasper, and attaching the surgical suture needle to the needle. Using a surgical suture needle gripper to secure and hold. The suture tip is inserted into and attached to the receiving end of the surgical suture needle. The second suture grip is positioned between the first suture grip and the spool. After the second suture grasper is closed to grasp the suture, the second suture grasper is advanced downstream toward the surgical suture needle to reduce suture tension. The tension on the suture is reduced by moving the second suture gripper a predetermined distance. The first suture grasper is opened to release the suture and the first suture grasper is for regripping the suture at a location between the second grasper and the suture spool. Is then moved toward the suture spool. The repositioned suture between the downstream side of the first suture gripper and the upstream side of the second suture gripper is cut. After the suture has been cut, the second suture gripper is directed toward the spool using a tension control system to increase the tension level between the suture needle and the second suture gripper. Displaced.
