An endotracheal intubation assistance apparatus is adapted to assist in insertion of an endotracheal tube into the trachea of a patient, and includes a movable tubular stylet, a graspable controller, and a viewing device. The stylet has a leading section, a body section, a tail section, and two slits extending through the body section and the tail section. The tail section is divided by the slits into first and second driven sheets. The viewing device includes an elongate body and a viewing head. The elongate body and the viewing head are movable through the graspable controller, and are extendable outwardly from the leading section. When the first and second driven sheets move relative to each other, the leading section swings synchronously a distal end of the endotracheal tube and the viewing head.一種插管輔助裝置，適用於將一氣管內管插入病人的氣管，該氣管內管包含一管身與一遠端，該插管輔助裝置包含一可動管狀通條、一握持控制器，及一觀看裝置。該可動管狀通條具可撓性，並沿一自身軸向具有一頭、身、尾段及一對貫穿該身、尾段的裂縫，該尾段被該對裂縫分割成一第一、第二被驅動片。該觀看裝置具有一細長本體及一觀看頭，該細長本體及該觀看頭能沿該軸向前後滑動地穿設於該握持控制器及自該可動管狀通條的該頭段的一內孔穿出，當該第一、第二被驅動片產生相對運動時，該頭段能同時帶動該氣管內管的遠端及該觀看頭擺動。
