Abstract
A needle camera adaptor includes a tube-shaped body having a proximal end, a distal end, a longitudinal axis, and a lumen that extends along the longitudinal axis. A centrally-located lateral access opening is formed in an outer wall of the tube-shaped body. A needle securing channel is formed in the outer wall and extends between the lateral access opening and the distal end of the tube-shaped body. A curved suture needle is disposed within the needle securing channel. The needle securing channel and the curved suture needle extend along an axis that defines an oblique angle with the longitudinal axis of the needle camera adaptor. A visualization device, facing distally, is positioned within the lumen at the proximal end of the tube-shaped body. The lateral access opening, the needle securing channel, and the curved suture needle are located within a field of view of the visualization device.
