A medical apparatus includes: a first image pickup section that is fixed to a body wall and picks up an image of an inside of a body cavity; a recording section that records in advance, in preparation for a case in which a predetermined image change occurs in a first image picked up by the first image pickup section, a predetermined image area in the first image or a coordinate for specifying the predetermined image area; and a display section that displays, when the predetermined image change occurs in the first image, the image area or the coordinate recorded in the recording section to be superimposed on the first image picked up by the first image pickup section.

Medical apparatus

A biopsy tissue sampling treatment instrument includes a stem portion having a predetermined length sufficient to puncture living tissue; a puncturing portion formed at a distal end of the stem portion and having a protruding surface portion expanding rearward along a puncture direction of the stem portion; a tissue holding surface provided on a rear side of the protruding surface portion in the puncturing portion and having an area large enough to hold the living tissue; a stopper member provided at a rear end of the stem portion and having an abutting portion capable of abutting against the living tissue punctured by the stem portion; and an operating member provided on the stopper member and configured to hold the stem portion to the living tissue, allowing the stem portion to puncture the living tissue. Consequently, the biopsy tissue sampling treatment instrument increases holding capacity for the living tissue to be extracted, allows living tissue to be extracted in sufficient sampling quantities, and makes it easy to take samples of living tissue at an intended depth in tissue.

A navigation apparatus includes: a storage portion that stores three-dimensional image data of an examinee that is previously acquired; an organ extracting portion that extracts a predetermined organ from the three-dimensional image data; a first region designating portion that designates a tumor in the three-dimensional image data; a blood vessel extracting portion that extracts a plurality of blood vessels that are inside the organ from the three-dimensional image data; a blood vessel classifying portion that classifies the blood vessels into either arteries or veins; and a second region extracting portion that, based on three-dimensional image information of the blood vessels, extracts a tumor resection region that is a region that is classified based on anatomical features of the organ and that includes a tumor.

Medical instrument and medical instrument control method

According to an insertion support system of the present invention, when a biopsy area is specified at a periphery of the bronchi, the barycenter of the biopsy area is extracted. A circle centering on the barycenter is determined as a search area. The search area is expanded until the bronchi are located within the search area. A point in the search area to which the bronchi first reach is determined as an end point. A first route choice connecting the end point and a start point is determined. If the first route choice has not been registered yet, the first route choice is registered as a first registered route. Accordingly, a location of interest can be specified as an arbitrary region, and navigation leading to the specified region is appropriately set.

In a camera head for an endoscope, a camera system for an endoscope, and an endoscope system of the invention, a camera head section has: an adaptor connection section to be connected to an eyepiece section of an endoscope that enables observation of inside of a body cavity of a subject; a CCD which picks up an observation image from the eyepiece section connected by the adaptor connection section; an image signal processing device which processes an image signal of the observation image picked up by the CCD; a cable including a connector as an output device which outputs the image signal from the image signal processing device; and a recording device which records the image signal.

Camera head for endoscope, camera system for endoscope, and endoscope system

With a bronchial tube insertion support system according to the present invention, a route setting unit comprises a route starting-point setting function for setting the insertion starting-point of a bronchial tube, a region-of-interest setting function for setting a region of interest serving as the insertion end-point of the bronchial tube, a route extracting function for extracting an insertion route from an insertion start point to an insertion end point, and a route verifying function for performing verification of the extracted insertion route. According to these functions, of multiple insertion routes, the most appropriate insertion route when performing insertion support is determined.

Insertion support system

In an insertion support system according to the present invention, on the basis of the rotation angle data of the VBS images stored in the memory, an image processing unit rotates and corrects the VBS image and the thumbnail VBS images to generate the insertion support screen.

In an endoscope devicein accordance with the present invention, a navigation screenis displayed. The navigation screenincludes: an endoscopic live image display areain which a live image produced by a bronchoscopeis displayed; a VBS image display areain which a VBS image is displayed; and a thumbnail VBS image areain which images constructed by reducing VBS images that represent all branch points on a route are displayed as thumbnail VBS images representing branch points. Consequently, an endoscope can be reliably navigated to reach a target region using guide images that represent actual branch positions.
