ABSTRACT:
A surgical suturing device for repairing wounds and incisions. In a first aspect of the invention, a slender elongated rod is connected to a movable handle to bring together a pair of pivotally connected needle holders. The needle holders have a pair of phased latches which control wire-like retainers which move in and out of end portions of the pivotally connected needle holders. The wire-like retainers interlock with circular grooves in opposite thread and point end portions of a surgical needle. Each time the slender rod is advanced toward the needle holders, the needle holders pivot toward each other and the rod simultaneously contacts the latches to alternately hold and release the thread and end portions of the needle. In a second aspect of the invention, each time the slender rod is advanced toward the needle holders, resilient members on sides of the needle holders simultaneously depress to alternately hold and release the thread and point end portions of the needle.
