The present invention discloses an endoscope head apparatus comprising a head mechanism, an elastic element, a support portion, a first wire, a second wire and a bilaterally flexible body. The elastic element is connected to the head mechanism and has a first accommodating space therein. The support portion is connected to the elastic element and has a second accommodating space therein. The first wire and the second wire are connected to head mechanism. The bilaterally flexible body is located at the first accommodating space, and connected to the head mechanism and the support portion respectively, and has a first bendable surface and a second bendable surface. The bilaterally flexible body can swing toward the first surface or the second surface by pulling the first wire or the second wire.本發明係揭露一種內視鏡擺頭裝置,包含擺頭機構、彈性元件、支撐部、第一線體、第二線體及雙向可撓體。擺頭機構具有內視鏡頭及相面對之第一、第二連接部。彈性元件係連接於擺頭機構,此彈性元件內具有第一容置空間。支撐部係連接於彈性元件,此支撐部具有第二容置空間。第一、第二線體,係各別連接第一連接部及第二連接部。雙向可撓體係位於第一容置空間,一端連接擺頭機構,另一端連接支撐部,雙向可撓體具有可彎折之一第一面及一第二面。可藉由拉動第一線體或第二線體,各別朝第一、第二面擺動。1‧‧‧內視鏡擺頭裝置2‧‧‧擺頭機構20‧‧‧內視鏡頭21‧‧‧第一連接部211‧‧‧第一連接孔22‧‧‧第二連接部3‧‧‧彈性元件31‧‧‧第一容置空間4‧‧‧支撐部5‧‧‧雙向可撓體51‧‧‧第一面52‧‧‧第二面61‧‧‧第一線體62‧‧‧第二線體
