To provide an imaging apparatus, a display system and a surgery system capable of coping with various surgical procedures and affected parts and widely applying endoscopic surgery.SOLUTION: An imaging apparatus 10 is configured to be capable of imaging a body cavity, and includes an imaging element 11, an opening member 12, an optical member 13, and a fixing member 14. The opening member 12 includes a tubular portion 120 extending from a body surface 5 to an abdominal cavity 2. The optical member 13 is a member that receives light reflected in the abdominal cavity 2 and guides the incident light to the imaging element 11. The fixing member 14 is a member which fixes at least one of the optical member 13 and the imaging element 11 to the opening member 12.SELECTED DRAWING: Figure 2【課題】 種々の術式や患部に対応することができ、内視鏡下手術を広く適用することが可能な撮像装置、表示システムおよび手術システムを提供する。【解決手段】 撮像装置１０は、体腔を撮像することが可能に構成されており、撮像素子１１と、開口部材１２と、光学部材１３と、固定部材１４と、を有する。開口部材１２は、体表５から腹腔２まで延びる筒状部分１２０を含む。光学部材１３は、腹腔２内で反射された光が入射され、その入射光を撮像素子１１まで導く部材である。固定部材１４は、光学部材１３および撮像素子１１の少なくとも一方を開口部材１２に固定する部材である。【選択図】 図２
