Device and method to display the angle of view endoscopically when using a multi-angle endoscope

摘要

An endoscope comprises an elongate shaft assembly, a window, a viewing angle adjustment assembly, and an indicator feature. The window is located at the distal end of the shaft assembly. The shaft assembly is configured to transmit a view acquired through the window. The viewing angle adjustment assembly is operable to selectively change a viewing angle associated with the window. The indicator feature is positioned to be visible within a view acquired through the window. The indicator feature is configured to indicate the viewing angle associated with the window.
