The present invention describes a variety of detachable secondary imaging endoscope devices, can be used together with endoscope to provide the additional visual field, so as to which the multiple regions of body cavity are imaged simultaneously. In some variations, secondary imaging endoscope device includes the second light source of the corresponding first light source and the second image-forming component and position what and the neighbouring second place in first position at the first position on endoscope attaching member, the first image-forming component and the position what endoscope attaching member being configured to be arranged on endoscope. In some variations, secondary imaging device includes the fluid conveying module with one or more ports with what fluid conveying. It can be combined or be arranged together by multiple synchronous images that secondary imaging endoscope device image-forming component and main endoscopic imaging element obtain, to form the successive views of body cavity.本發明描述了多種可拆卸式次級成像內窺鏡裝置，其可以與內窺鏡一起使用以提供附加的視野，從而可以同時對體腔的多個區域成像。在一些變型中，次級成像內窺鏡裝置包括構造成布置在內窺鏡上的內窺鏡附裝構件、第一成像元件和位於內窺鏡附裝構件上的第一位置處的對應的第一光源、以及第二成像元件和位於與第一位置鄰近的第二位置處的第二光源。在一些變型中，次級成像裝置包括具有用於流體輸送的一個或多個端口的流體輸送模塊。通過次級成像內窺鏡裝置成像元件和主內窺鏡成像元件得到的多個同步圖像可以被結合或布置在一起，以形成體腔的連續視圖。
