  • Medical suturing device, a single-strike die mechanism, and a method of using said die mechanism for forming the medical suturing device
    Patent number: 5411521
    Abstract: A single-strike die mechanism includes a rotatable cam drive ring driven to impart through a cam mechanism linear motion to at least three crimping dies. The crimping dies are symmetrically arranged within a die guide and simultaneously actuated to move in a radial direction toward a centerline of a surgical needle. A surgical suture is axially inserted within a hollow barrel end of the needle, and the barrel end is crimped by the crimping dies to secure the suture therein. A method for operating the single-strike die mechanizes the procedure for securing the suture within the barrel end of the needle.
