Abstract: A cannula includes a first tubular member having a first longitudinal axis, a second tubular member having a second longitudinal axis, a connector that connects the first and second tubular members in series, and a rear bearing that supports the second tubular member in a three-dimensionally pivotable manner around an axis intersecting the second longitudinal axis. The first tubular member has a first through-hole into which a flexible and elongated medical treatment device is insertable, and is supported by a trocar in a state where the first tubular member extends through the trocar attached to a body wall of a patient. The second tubular member has a second through-hole into which the medical treatment device is insertable. The connector connects the first and second tubular members in a pivotable manner around an axis orthogonal to a plane including the first longitudinal axis and the second longitudinal axis.

Abstract: Provided is a stereoscopic endoscope device including a single objective lens that collects light from a subject and forms an image of the light; a light splitting section that splits the light collected by the objective lens; image-capturing devices that capture optical images of the subject at imaging positions of the split beams of the light; focal-position adjusting sections that give optical path lengths different from each other to the split beams of the light; a calculation section that calculates an object distance between each point on the subject and the objective lens from 2D images acquired by the image-capturing devices; and a parallax-image generating section that generates a plurality of viewpoint-images of the subject when observed from a plurality of viewpoints, by using the calculated object distance.

Abstract: An appropriate stereoscopic image of a subject is readily acquired. Provided is a stereoscopic endoscope device including two image capture elements spaced apart from each other and disposed at a distal end of an insertion section to be inserted into a subject; an angle changing mechanism that changes a relative angle between optical axes of the image capture elements; a distance sensor that detects the distance from the image capture elements to the subject; and a controller that controls the angle changing mechanism on the basis of the distance detected by the distance sensor.
