1. An endoscopic surgical robotic system, comprising:
an endoscope pre-selected according to a lesion inside of an organ, wherein the endoscope comprises a fluid inlet channel for flowing an irrigation fluid to the organ;
a sheath for guiding the endoscope;
a suction channel located within the sheath for removing the irrigation fluid from the organ;
a pressure measuring channel located along the sheath, wherein the pressure measuring channel is connected to a pressure detector constructed to measure a pressure within the organ;
a pressure relief valve in fluid communication with the sheath, wherein once the pressure within the organ monitored via the pressure detector increases above a threshold, the pressure relief valve opens to allow removal of the irrigation fluid in the suction channel, thereby lowering the pressure within the organ;
a first holder for holding the sheath;
a second holder for holding the endoscope, wherein the first holder and the second holder are designed to move co-axially so as to move the endoscope in and out of the sheath; and
a robotic arm for controlling a movement of the sheath, wherein the robotic arm is connected to the first holder.
