A method for assembling an imaging endoscopy system for use in gastroscopy, the imaging endoscopy system comprising a base unit; a hand controller; an umbilical section releasably connecting the base unit and the hand controller; an insertion section having a proximal end connected to the hand controller and a distal end for insertion into a subject, the distal end having a steering section and a distal tip, wherein: the hand controller includes two rotational drive wheels for controlling bending of the steering section; the distal tip includes an imaging chip for imaging a region of tissue of interest; the insertion section includes four steering wires connecting the rotational drive wheels of the hand controller and the steering section, the steering section having two axes of bending; the insertion section further including an electrical conductor for conducting electrical signals from the imaging chip to the proximal end of the insertion section; the insertion section further including lumens adapted to: deliver insufflation gas to the distal tip; deliver irrigation liquid to the distal tip; provide suction at the distal tip; provide a conduit for at least one surgical tool to be inserted along the insertion section to the distal tip; wherein the method comprises: disconnecting a used umbilical section from the base unit and disposing of said used umbilical section, along with a connected used hand controller and insertion section; opening at least one sealed container containing: a hand controller, in sterile condition; an umbilical section, in sterile condition; and an insertion section, in sterile condition, and connecting the sterile umbilical section to the base unit to provide an imaging endoscopy system ready for use. a base unit; a hand controller; an umbilical section releasably connecting the base unit and the hand controller; an insertion section having a proximal end connected to the hand controller and a distal end for insertion into a subject, the distal end having a steering section and a distal tip, the hand controller includes two rotational drive wheels for controlling bending of the steering section; the distal tip includes an imaging chip for imaging a region of tissue of interest; the insertion section includes four steering wires connecting the rotational drive wheels of the hand controller and the steering section, the steering section having two axes of bending; the insertion section further including an electrical conductor for conducting electrical signals from the imaging chip to the proximal end of the insertion section; the insertion section further including lumens adapted to: deliver insufflation gas to the distal tip; deliver irrigation liquid to the distal tip; provide suction at the distal tip; provide a conduit for at least one surgical tool to be inserted along the insertion section to the distal tip; deliver insufflation gas to the distal tip; deliver irrigation liquid to the distal tip; provide suction at the distal tip; provide a conduit for at least one surgical tool to be inserted along the insertion section to the distal tip; wherein the method comprises: disconnecting a used umbilical section from the base unit and disposing of said used umbilical section, along with a connected used hand controller and insertion section; opening at least one sealed container containing: a hand controller, in sterile condition; an umbilical section, in sterile condition; and an insertion section, in sterile condition, and connecting the sterile umbilical section to the base unit to provide an imaging endoscopy system ready for use. disconnecting a used umbilical section from the base unit and disposing of said used umbilical section, along with a connected used hand controller and insertion section; opening at least one sealed container containing: a hand controller, in sterile condition; an umbilical section, in sterile condition; and an insertion section, in sterile condition, and a hand controller, in sterile condition; an umbilical section, in sterile condition; and an insertion section, in sterile condition, and connecting the sterile umbilical section to the base unit to provide an imaging endoscopy system ready for use.
