[Object] To make it possible to execute the insertion of an endoscope into an inside of an observation object more promptly, and to reduce the burden of an endoscope operator more.

[Solution] An endoscope apparatus according to the present disclosure includes: an endoscope unit at least a part of which is inserted into an inside of an observation object and that propagates an image of the inside of the observation object irradiated with illumination light; a light source unit that emits the illumination light illuminating the inside of the observation object to the endoscope unit; an imaging unit that captures an image of the inside of the observation object having been propagated from the endoscope unit and generates a captured image of the inside of the observation object; and a control section that performs driving control for the endoscope unit, the light source unit, and the imaging unit. A radiation angle of the illumination light is changeable, and the control section changes the radiation angle of the illumination light in accordance with whether an insertion portion being a part of the endoscope unit having been inserted into the inside of the observation object is moving in the inside of the observation object or has stopped.

An endoscopic system including an endoscope including an optical element including a marker disposed thereon, an optical formation device that changes an angle of view, and an image capturing device receiving light from the optical element via the optical formation device and processing circuitry that identifies the angle of view from an image captured by the image capturing device based on the marker in the image.

Illumination light is continuously emitted and auxiliary measurement light is emitted in the form of a pulse at a specific frame interval. A subject illuminated with illumination light is imaged to obtain a first taken image. A subject illuminated with illumination light and auxiliary measurement light is imaged to obtain a second taken image. A specific image where a measurement marker obtained from the second taken image is displayed in the first taken image is displayed on a display unit.

This invention relates generally to a medical device, and more specifically, to a vaginal surgical apparatus. In one embodiment, an apparatus includes, a vaginal manipulator probe that is at least partly insertable into a vagina, the vaginal manipulator probe including an end portion that includes a bullous tip and that includes a space that accommodates a cervix therewithin; and at least one prominence incorporated with the vaginal manipulator probe operable to assist with identifying one or more positions of at least one anatomical structure or orienting the vaginal manipulator probe.

An illumination optical system includes a diffusion element that diffuses illumination light entering from a light source, the diffusion element emitting the illumination light. The diffusion element is formed by dispersing fine particles of at least one kind in a homogeneous medium that is made of a material different from the fine particles, and the diffusion element satisfies a specific conditional expressions.

In certain embodiments, an illuminating endoprobe system includes one or more light sources, a housing, a vitreous visualization fiber, and a general illumination fiber. The light sources generate a visualization light and an illumination light. The housing receives the visualization and illumination light, and has a probe tip with a probe axis. The vitreous visualization fiber transmits the visualization light through the probe tip. The visualization light has a visualization axis and a visualization beam angle at the probe tip. The general illumination fiber transmits the illumination light through the probe tip. The illumination light has an illumination axis and an illumination beam angle at the probe tip. The illumination beam angle is greater than the visualization beam angle, and the illumination axis is at an offset angle relative to the visualization axis, where the offset angle greater than 5 degrees.

An illumination lens consists of two lenses consisting of a first lens and a second lens arranged in this order from a light source side, and surfaces of all the lenses have a planar shape or a convexly spherical shape. An incident surface of the first lens is a convex surface, and an emission surface of the second lens is a flat surface. An intersection of a ray incident in parallel to an optical axis at a height of 0.25H and a ray incident in parallel to the optical axis at a height of 0.5H is positioned only inside the illumination lens in a case in which an outer diameter of the first lens is denoted by 2H. Predetermined Conditional Expression related to a focal length of the illumination lens and a focal length of the first lens is satisfied.

The invention aims at providing a measurement support device, an endoscope system, and a processor for an endoscope system capable of displaying an accurate indicator with a simple configuration. In a measurement support device related to one aspect of the invention, the coordinates of a spot, and coordinates of points indicating an actual size of a measurement target in a subject and indicating a circular marker distorted in accordance with distortion aberration of an imaging optical system are stored in association with each other in a storage unit, the coordinates of the points indicating the circular marker are acquired with reference to the storage unit on the basis of the measured coordinates of the spot, and the circular marker is displayed on the basis of the acquired coordinates. Thus, the distance measurement is unnecessary, the configuration is simple, and the processing load is low. Additionally, since the circular marker is displayed in the vicinity of the spot (for example, centering on a spot position), there is little deviation between the spot position and a marker position, the circular marker is accurate as an indicator. Additionally, since the indicator is not widely displayed, there is little processing load.
