摘要： The present disclosure provides a medical observation device to achieve improvement in functionality resulting from switching of optical elements and miniaturization of the device. The medical observation device includes: an imaging optical system configured to capture an image of a subject; an image sensor configured to photoelectrically convert the image of the subject captured by the imaging optical system; and an element holding frame configured to hold a plurality of optical elements and to be capable of being rotated around a rotation shaft. An axial direction of the rotation shaft is set to a direction orthogonal to an optical axis direction that is a direction of a line from the imaging optical system to the image sensor, and the element holding frame is rotated and thus at least one of the optical elements among the plurality of optical elements is positioned on an optical axis.

摘要： To enable a moving object to be movable even when electromotive driving of the moving object is not possible and prevent inconvenience from occurring during medical procedures. A medical observation device includes: an imaging optical system configured to capture an image of a subject; an image sensor configured to photoelectrically convert the image of the subject captured by the imaging optical system; a driving force transmission mechanism configured to have a transmission gear and to transmit a driving force to a moving object; a manual manipulation knob configured to be manipulated to rotate in an axial rotation direction of a fulcrum shaft and to be capable of moving between a first position and a second position in an axial direction of the fulcrum shaft; a switch gear configured to be connected to the manual manipulation knob and to be integrated with the manual manipulation knob and rotate in the axial rotation direction, and to be integrated with the manual manipulation knob and move in the axial direction between a meshing position and a non-meshing position; and a driving motor configured to give a driving force to the moving object. Meshing of the switch gear and the transmission gear is released at the non-meshing position, and the switch gear and the transmission gear mesh with each other at the meshing position.
