Improved flexible robotic endoscopy system

An endoscope system comprising:

• (a) an endoscope with a control body, an insertion portion, a first user interface and a plurality of channels,
• (i) wherein the channels include at least one of a gas feeding channel, a water feeding channel and a suction channel;
• (ii) wherein the first user interface controls valve functions of at least one of the gas feeding, the water feeding and the suction;
• (b) a valve control unit comprising:
• (i) one or more electrical valves to control flow through at least one of the gas feeding channel, the water feeding channel and the suction channel;
• (c) a surgeon console unit (SCU) including a second user interface, wherein the second user interface controls valve functions of at least one of the gas feeding, the water feeding and the suction;
• and
• (d) a priority control module for processing one or more control signals from the first user interface and the second user interface based on a set priority, wherein the control signals are transmitted to control the corresponding electrical valves.

An endoscope comprising:

• (a) an insertion portion having a flexible insertion tube and a distal end with a distal end face, wherein the insertion portion has a first surgical instrument channel and a second surgical instrument channel;
• (b) a first quadrant, a second quadrant, a third quadrant and a fourth quadrant arranged on the distal end face;
• (i) wherein the first quadrant and third quadrant are at opposite sides of the center of the distal end face;
• (ii) wherein the second quadrant and the fourth quadrant are at opposite sides of the center of the distal end face;
• (iii) wherein the quadrants are arranged in a quadrant sequence;
• (c) an objective camera lens located in the first quadrant;
• (d) a first surgical instrument channel outlet located in the second quadrant;
• (e) an auxiliary channel outlet located in the third quadrant;
• and
• (f) a second surgical instrument channel outlet located in the fourth quadrant.
