Hermetically sealed imaging system for medical applications

An imaging system comprising:

• an optical-system holding member for holding an optical system to form an optical image of a subject;
• an imaging-device holding member for holding an imaging device to obtain the optical image formed by the optical system;
• a case for hermetically enclosing the optical-system holding member and the imaging-device holding member, the optical-system holding member and the imaging-device holding member are connected through a retractable elastic member to constitute the case;
• a hermetic connector for hermetically sealing the case, the hermetic connector being electrically connected to the imaging device;
• a power generator for generating a driving force to move either the optical-system holding member or the imaging-device holding member, the power generator being arranged in the case and generating a driving force based on an electric energy supplied thereto via the hermetic connector;
• and
• a driving-force transfer member for connecting the power generator and either the optical-system holding member or the imaging-device holding member to transfer the driving force of the power generator to either the optical-system holding member or the imaging-device holding member.

• an imaging-device holding member for holding the imaging device, the imaging-device holding member being disposed in the internal space of the case;
• an optical-system holding member for holding the optical system so that the optical system is movable forward and backward along the optical axis relative to the imaging device, the holding member being disposed in the internal space of the case, the optical-system holding member having a slide contact surface which is slidable on the inner wall of the case, a protrusion on the outer surface of the optical-system holding member coming into contact with a contact portion on the inner wall of the case to restrict the forward movement of the optical-system holding member, and the rear end, including the protrusion of the optical-system holding member coming into contact with the imaging-device holding member to restrict the backward movement thereof along the optical axis;
• a power generator for generating a driving force to move the holding member, the power generator being arranged in the case and generating a driving force based on an electric energy supplied thereto via the hermetic connector;
• and
• a driving-force transfer member for connecting the power generator and the holding member to transfer the driving force of the power generator to the holding member.
