摘要：
An apparatus for anulus fibrosus repair includes a shaft, a pair of curved suturing needles mounted in parallel on the shaft, and a rotational driving mechanism connected to the shaft, which is configured to rotate the shaft and the pair of needles about a rotation axis of the shaft. Each needle includes a substantially semi-annular body having a proximal end, a distal end, an inner periphery, and an outer periphery, and an arm extending radially inward from the proximal end, in which a concavity is formed in the body proximate to the distal end extending in a direction away from it. Also disclosed is a suturing technique associated with use of the repair apparatus.
