Abstract: An endoscope includes an insertion portion that is inserted into a subject, and a suction channel that suctions a liquid along with a crushed calculus. The suction channel includes a channel main body, which is inserted in the insertion portion, and a small-diameter channel portion that is provided on a distal end side of the channel main body and has an inner diameter smaller than an inner diameter of the channel main body. The suction channel is configured to satisfy the relational expression R1/R2>1.27, where R1 represents the inner diameter of the channel main body and R2 represents the inner diameter of the small-diameter channel portion.

Abstract: Method of removing a calculus, such as a kidney stone, from within the calyx involves inserting the distal end portion of a medical tube into the calyx, positioning the distal end portion of the medical tube within a region of the calyx, such as the inferior calyx, while referring to a radiolucent image showing the distal end portion, pumping fluid into the calyx through the lumen of the medical tube, and draining the calculus from inside the calyx through the gap between the inner wall of the calyx and the outer circumferential surface of the distal end portion of the medical tube.

Abstract: An endoscope system includes an endoscope that acquires an image of a subject and a processor. The processor acquires position and posture information of the endoscope, estimates a three-dimensional shape of the subject based on the image and the position and posture information, generates, based on the position information, a cross section crossing a trajectory on which the endoscope passed, and determines an erroneous estimation portion based on a shape characteristic of the three-dimensional shape on the cross section.

Abstract: A medical apparatus includes a model-image generating section configured to generate a model image obtained by modeling a shape of an inside of a subject, a coordinate calculating section configured to detect a three-dimensional position of a feature point of the inside of the subject, set a polar coordinate on the basis of a position of the feature point, and calculate an arbitrary three-dimensional position of the inside of the subject according to the polar coordinate, and an image generating section configured to show the arbitrary three-dimensional position of the inside of the subject on the model image on the basis of one angle component among components of the polar coordinate calculated by the coordinate calculating section and a value obtained by correcting the one angle component according to another angle component.

Abstract: A navigation system includes an alignment unit configured to generate corrected position information in which position information of a viewpoint of an endoscope that is inserted in a subject is aligned with a three-dimensional image of a luminal organ, a determination unit configured to determine performance/non-performance of observation of a branch conduit based on the corrected position information, a target setting unit configured to set one unobserved conduit as a first target region based on a distance between the position information of the current viewpoint and the unobserved conduit, and a navigation information generation unit configured to generate navigation information for the first target region.
