Non-contact Endoscopy at Covid-19 Outbreak

After an overnight fasting and drinking 1000 mL water and simethicone for gastric dilatation and preparation, the study subject positions himself (herself) on the examination bed in Room A, while the operating doctor sits in Room B at the remote control workstation instructing her to swallow the capsule via the audio-visual exchange system. After the capsule entering the stomach, the doctor manipulated the two joysticks on the remote control workstation, mobilizing the robotic magnetic arm, and simultaneously driving the precise movement and rotation of the capsule to perform the gastric examination.
