Suturing end effector includes the first jaw member, the second jaw member and a helical needle. First and second jaw members are moved relative to each other, in open configuration. Each first and second jaw member defines that the first gang of wells limits the first spiral path when the first and second jaw members are in closed configuration. The helical needle rotates spiral path and retracts between extended position. The helical needle be configured to absorb water between deep the first jaw members of suture through tissue and the second jaw members helical needle rotatably advance through spiral path and be configured with independently of can relative to suture withdraw when from progressive position to retracted position.
