An endoscopic surgical instrument includes a flexible tube, a grasping and fastening end effector coupled to the distal end of the tube, and a manual actuator coupled to the proximal end of the tube. The manual actuator is coupled to the end effector by a plurality of flexible cables which extend through the tube. The tube contains a lumen for receiving a manipulable endoscope and the end effector includes a passage for the distal end of the endoscope. The end effector has a store for a plurality of male fastener parts, a store for a plurality of female fastener parts, a rotatable grasper, a rotatable fastener head for aligning a female fastener part and a male fastener part with tissues therebetween, and a firing member for pressing a male fastener part through tissues grasped by the grasper and into a female fastener part. According to a presently preferred embodiment the overall diameters of the flexible tube and the end effector (when rotated to the open position) do not exceed approximately 20 mm so that the instrument may be delivered transorally to the fundus of the stomach. The manual actuator is provides with a lock-out feature which prevents firing male fastener parts before the fastener head is closed. The instrument is advantageously utilized in a fundoplication procedure.
[ What is claimed is:] [1.] An endoscopic surgical instrument for deploying a two part fastener having a male fastener part and a female fastener part, comprising:a) a flexible tube having a proximal end and a distal end;b) at least one control cable having a proximal end and a distal end and extend
[ What is claimed is:] [1.] An endoscopic surgical instrument for deploying a two part fastener having a male fastener part and a female fastener part, comprising:a) a flexible tube having a proximal end and a distal end;b) at least one control cable having a proximal end and a distal end and extending through said tube;c) an end effector coupled to said distal end of said tube, said end effector configured to hold the male fastener part and the female fastener part in opposed relation and including a rotatable member having a connected end and a free end, the rotatable member being configured to rotate between a first position in which the free end is located distally of the connected end and a second position in which the connected end is located distally of the free end;d) a movable fastener coupled to said distal end of said at least one control cable, said movable fastener configured to move one of the male fastener part and the female fastener part into locking relation with the other of the male fastener part and the female fastener part; ande) an actuator coupled to said proximal end of said tube and said proximal end of said at least one cable to move said movable fastener.
