ABSTRACT:
An endoscopic surgical instrument for releasably grasping a curved needle, the instrument employing a handle at a first end of a shaft, the handle for operating a set of opposed jaws at a second end of the shaft. The jaws are serrated and have a channel through the top jaw and an arcuate groove in the top surface of the bottom jaw. The nose of the jaws is slotted to receive the forward portion of the curved needle while the central portion of the curved needle rests in the groove in the top surface of the bottom jaw, and the rear portion of the curved needle extends through the channel. With the jaws compressed and holding the needle in place, the surgeon may then insert the combination through a canulus to suture the tissue at a remotely-located operation site.
