A uterine manipulator system comprising: 1) a shaft configured to pass through a stabilizer aperture; wherein the shaft contains a hollow inner channel coupling a distal end of the shaft to a proximal end of the shaft; and wherein the distal end of the shaft includes at least one of a distal shaft aperture in fluid communication with the hollow inner channel, and the proximal end of the shaft includes at least one of a proximal shaft aperture in fluid communication with the hollow inner channel; 2) a tip portion including a first portion, a second portion, and a third portion; wherein the second portion is located between the first portion and the third portion; wherein the first portion is configured for coupling to the distal end of the shaft; wherein the first portion, the second portion, and the third portion respectively include a first diameter, a second diameter, and a third diameter; and wherein at least one or more aperture is located on the second portion and is in fluid communication with the distal shaft aperture and the hollow inner channel; 3) a handle wherein the proximal end of the shaft is configured to couple to the handle; and 4) an inlet coupled to the handle and in fluid communication with the hollow inner channel of the shaft; characterized in that the tip portion is a bulbous tip portion having a maximum bulbous diameter greater than a maximum diameter of the shaft, that the second diameter of the tip portion is smaller than the first diameter and the third diameter; that said at least one or more aperture is located on the second portion of the bulbous tip portion of smaller diameter than the first diameter and the third diameter; that the maximum first diameter and third diameter is 5mm to 10mm; and that the bulbous tip portion includes a continuously convexly sloped perimeter extending distally from the third diameter and crossing the longitudinal axis to form a closed, rounded distal end of the bulbous tip portion. 1) a shaft configured to pass through a stabilizer aperture;
