Insertion methods for robotic surgical devices

An insertable robot for minimally invasive surgery includes a tube array having a guide tube housed within a straightening tube. The guide tube includes a curved working end. The guide tube may be axially translated and rotated relative to the straightening tube such that the curved working end is constrained inside the straightening tube, causing the curved working end to achieve a smaller dimension. The tube array is inserted into a working channel on an endoscope, resectoscope or trocar. Once the tube array is inserted, the curved working end of the guide tube is translated forward beyond the distal end of the working channel, allowing the curved working end to return to its pre-formed shape. A surgical tool is inserted through the guide tube for an operation. The straightening tube allows the guide tube curved working end to be temporarily straightened during insertion and removal of the tube array.
