ABSTRACT:
An endoscopic suturing device having an interlocking trigger assembly for preventing premature needle deployment. The suturing device comprises a handle assembly that includes a movable handle interlocking with a trigger. The suturing device further comprises an end effector having an upper jaw, a lower jaw and a needle/suture mechanism. The motion of the movable handle causes the upper jaw to move relative to the lower jaw. The activation of the trigger causes deployment of the needle/suture mechanism. The interlocking mechanism ensures that the needle/suture is deployed only when the upper jaw is below a maximum allowable distance from the lower jaw.
