Endoscope and method of use

An endoscopic device for use with a tool, the endoscopic device, comprising:

• an elongated shaft having an open passageway extending therethrough;
• a sensor assembly comprising an image sensor;
• an inner sleeve disposed within the open passageway;
• a flex circuit coupled to the sensor assembly and disposed within the open passageway, wherein the flex circuit comprises a flex circuit deflecting surface, wherein the flex circuit deflecting surface is configured to displace upon advancement of the tool against the flex circuit deflecting surface;
• and
• a flexible arm structure, wherein the flexible arm structure has a first living hinge portion and a second living hinge portion, the first living hinge portion and the second living hinge portion both having inherent spring forces, wherein the flexible arm structure has a flexible arm deflecting surface distal to the first living hinge portion, a first end coupled to the sensor assembly, and a second end within the open passageway and affixed to the inner sleeve, and wherein the flexible arm structure comprises an insertion position when restrained within the elongated shaft such that the flexible arm structure positions the sensor assembly such that an optical axis of the image sensor is angled relative to a shaft axis of the elongated shaft.
