Provided is a microscope apparatus including: a microscope section configured to perform magnified observation of a subject's eye while obtaining a red reflex caused by irradiating a fundus of the subject's eye with illuminating light; a holding section configured to hold the microscope section; and a tilting section configured to tilt an illumination optical axis which is an optical axis of an illumination optical system, and an observation optical axis which is an optical axis of an observation optical system in the microscope section, around a tilt reference point in an interior of the subject's eye as a base point, while maintaining a substantially coaxial state between the illumination optical axis and the observation optical axis.

Microscope apparatus and control method

There is provided a medical observation apparatus including: a determination unit which determines an apparatus to be used based on a captured image for medical use captured by an imaging device; and a display control unit which causes a related image for medical use corresponding to the determined apparatus and the captured image for medical use to be displayed.

Medical observation apparatus and control method

A medical observation apparatus includes: a camera including a first imager including a plurality of pixels and configured to image a first medical captured-image in which an observation target is imaged, and a second imager including a plurality of pixels, and configured to image a second medical captured-image in which the observation target is imaged, the second imager including more effective pixels than the first imager; and a display controller configured to cause displays to display the first medical captured-image and an image that corresponds to a region set to the second medical captured-image on a display screen of the respective one of the displays corresponding thereto, wherein one of the first medical captured-image and the second medical captured-image is a medical captured image for a right eye, and another one of the first medical captured-image and the second medical captured-image is a medical captured image for a left eye.

Hard disk drive with magnetic-disk substrate

There is provided a medical observation apparatus including: a determination section configured to determine, on a basis of distance between a part corresponding to a sterile region and an object existing in a periphery of the part corresponding to the sterile region, if an approaching state in which an object is approaching the part corresponding to the sterile region exists; and a notification control section configured to cause a notification of the approaching state to be issued, on a basis of a determination result of the approaching state.

Medical observation apparatus and state notification method

There is provided a medical sterile cover including: a layered structure in which a plurality of covering members that cover a medical observation apparatus to ensure a sterile state of the medical observation apparatus is layered; and a detachment section configured to detach the layered plurality of covering members layer by layer.

Medical sterile cover and medical observation apparatus

A drape maintains a sterile state of a surgical microscope by covering the surgical microscope that enlarges and observes a minute portion of an observation object, and includes: a main body portion that is folded in an unused state and expanded in an in-use state to cover the surgical microscope; and a handle portion that promotes a state change of the drape from the unused state to the in-use state.
