Abstract
A needle driver (100) for fixedly positioning a curved suture needle (101) in a channel (114) of an inner rod (109) thereof and in a preferred 90 degree orientation with respect to the longitudinal axis of the inner rod. The needle driver includes an outer tube (102) with a beveled edge (110) positioned transversely at the distal end thereof. The beveled edge includes a substantially straight segment (119) inclined at a preferred angle with respect to the longitudinal axis of the outer tube. The channel of the inner rod includes an undercut surface (116) and an intermediate surface (117) extending longitudinally therefrom. The undercut surface is formed at a preferred angle with respect the longitudinal axis of the inner rod, whereas the intermediate surface is substantially parallel to the axis. The inclined, substantially straight segment of the outer tube beveled edge and the undercut and intermediate surfaces of the inner rod channel cooperate when urged toward each other to fixedly position a curved suture needle in the desired 90 degree orientation. The needle driver also includes a generally U-shaped spring handle (107) attached proximate the proximal ends (122, 134) of the inner rod and outer tube for urging the outer tube beveled edge and inner rod channels toward each other.
