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 a light source for illumination of a region of tissue of interest and an imaging chip for imaging the 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 providing electrical power to the light source and 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 a light source for illumination of a region of tissue of interest and an imaging chip for imaging the 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 providing electrical power to the light source and 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.
