Robotic suturing device includes a slender bodies, actuator and needle holder. Slender bodies includes that distal end extends along longitudinal axis. Actuator can be between the first operating position and the second operating position. Curved needle holder extends outwardly away from end section or the slender bodies for being provided as part thereof of end section. Curved needle holder includes the farthest tip with distal portions, and limits curved channel and distal openings close to farthest side end. The curved needle holder being parallel between the place of longitudinal axis measurement starts curve and leaves longitudinal axis, or elongate body start to buckle away from longitudinal axis slender bodies connection handle can be at about 10 centimetres to about 20 centimetres. Equally, farthest tip can deviate the longitudinal axis and be less than about 7 millimeters along the distance perpendicular to the longitudinal axis.
