Abstract
An automated stitching device having a "C"-shaped arcuate needle which is incrementally advanced in a circular path. A toggle and drive plate arrangement is used to drive the needle, and a one-way clutch mechanism is used to engage and permit incremental advancement of the needle along its circular path. The "C"-shaped arcuate needle is mounted and driven at the distal end of an elongated shaft. The stitching device is particularly suited for microsurgery, laparoscopic surgery, and various less invasive surgical procedures, and particularly for the suturing of blood vessels including during cardiac bypass surgery.
