Surgical rotary capture instrument for gastric band closing

An endoscopic surgical instrument used in minimally invasive surgery for grasping and tightening a ligature band around an internal organ, wherein said ligature band comprises an elongated strap having a buckle end and a distal end, said buckle end having an aperture and a pull tab having a hole thereon and wherein said elongated strap is configured to encircle said internal organ and said distal end is configured to pass through and lockingly engage said aperture thereby tightening said ligature band around said internal organ, the instrument comprising:

• a hook tool configured to engage said hole and pull said pull tab in a first direction while said distal end is pushed through said aperture opposite to said first direction;
• a capture tool configured to engage a protuberance of said distal end and push said distal end after it has been threaded through said aperture;
• wherein said hook tool comprises a hook having a flat portion and a bend portion extending from said flat portion and wherein said flat portion is configured to slide along a flat surface of said pull tab and said bend portion has an inner surface radius matching a radius of said hole;
• and
• wherein said capture tool comprises a stationary jaw and a rotationally movable jaw and wherein said rotationally movable jaw is actuated by rotational motion of an elongated shaft.
