A tip section of a multi-camera endoscope includes a front-pointing camera on a planar surface of a distal end of the tip section and two side-pointing cameras positioned in depressions on a cylindrical surface in proximity to the planar surface such that the side field of view provided by the two side-pointing cameras partially overlaps with the front field of view provided by the front-pointing camera. The tip section further includes a working channel configured for insertion of a surgical tool and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.マルチカメラ内視鏡の先端部であって、該先端部の遠位端に又はそれに近接して位置決めした２つ以上の側方向きカメラであり、該２つ以上の側方向きカメラのそれぞれが各自に関連する個別照明器を有し、２つ以上の側方向きカメラが提供する視野は前方視及び側方視に及ぶ２つ以上の側方向きカメラと、手術道具を挿入するよう構成した工具チャネルと、内視鏡が挿入される体腔の膨張及び／又は洗浄用の経路流体インジェクタとを備えた先端部を、本明細書において提供する。【選択図】図３
