Document Type and Number:
Japanese Patent JP7027444
Kind Code:
B2
Abstract:
A method of attaching a surgical suture to a needle and testing the attachment includes dispensing a length of suture from a spool by using a first suture gripper, and using a surgical needle gripper for holding a surgical needle stationary. A leading end of the suture is inserted into and attached to a receiving end of the surgical needle. A second suture gripper is located between the first suture gripper and the spool. After the second suture gripper is closed for gripping the suture, the second suture gripper is advanced downstream toward the surgical needle to reduce the tension on the suture. The tension on the suture is reduced by moving the second suture gripper a pre-determined distance. The first suture gripper is opened for releasing the suture and the first suture gripper is moved toward the suture spool for re-grasping the suture at a location between the second gripper and the suture spool. The suture between the downstream side of the re-positioned first suture gripper and upstream side of the second suture gripper is cut. After the suture is cut, the second suture gripper is displaced toward the spool using a tension control system to increase the tension level between the needle and the second suture gripper.
