A video processor receives first and second images respectively acquired by an endoscope at first and second timings before and after a predetermined function is applied to a subject, generates first and second correction images respectively using first and second images, generates first and second post-correction images respectively obtained by causing the first and second correction images to act on the first and second images, extracts color components in the second post-correction image to find first and second distribution characteristic values, and calculates a degree of change of the second distribution characteristic value from the first distribution characteristic value.

Image analysis apparatus, image analysis system, and method for operating image analysis apparatus

An image analysis apparatus includes a processor including hardware. The processor extracts parts from each of a first image and a second image acquired after the first image, each of the extracted parts including an annular peripheral portion and a central portion having a color different from a color of the peripheral portion. The processor also sets the central portion as the analysis object region and calculates a brightness decrease degree of the analysis object region in the second image relative to the analysis object region in the first image.

Image analysis apparatus, image analysis system, image analysis apparatus operation method to analyze brightness change of subject

An image analysis apparatus includes a region extraction unit configured to determine, as analysis target regions, respective predetermined regions in a first image and a second image that are acquired at timings before and after execution of a predetermined action to a subject and inputted through an image input unit in a state where an endoscope is continuously inserted in the subject, a distribution characteristic value calculation unit configured to obtain a first distribution characteristic value by extracting a color component of the analysis target region in the first image, and to obtain a second distribution characteristic value by extracting a color component of the analysis target region in the second image, and an image analysis unit configured to calculate the degree of change in the second distribution characteristic value with respect to the first distribution characteristic value.

Image analysis apparatus for calculating degree of change in distribution characteristic values, image analysis system, and method for operating image analysis system

A medical instrument of the present invention comprises a spiral shaped portion provided at an insertion portion main body, for generating a force at the insertion portion main body to advance/retreat in a subject by a contact with a body wall of the subject, a balloon provided so as to expand radially in a radial direction of the insertion portion main body and capable of contact with the body wall, a suction opening portion provided between the spiral shaped portion and the balloon in the insertion portion main body, and a suction pipeline communicating with the suction opening portion, inserted into the insertion portion main body and connected to a suction pressure controller on a rear end side of the insertion portion main body in the insertion direction.

Medical instrument, endoscope and endoscope device

An endoscope of the invention is the endoscope for applying a propulsion force in a direction of insertion axis of an insertion portion main body in accordance with rotation of the insertion portion main body based on driving force of a driving member, and the endoscope includes a flexible elongated inner layer tube configured as a shaft of the insertion portion; and a spiral-shaped portion rotatable around the inner layer tube as an axial center based on the driving force of a motor, the spiral-shaped portion forming an outer surface of the insertion portion main body, in which the spiral-shaped portion is formed by a nondensely wound coil and a resin thin film provided so as to cover gaps of a wire forming the metal coil.

Endoscope, endoscope system, and method of manufacturing endoscope

Three magnetic field generating coils on the distal end side of the shape detection probe are provided in the curvable portion, and the first coil at the leading end position is placed at the position corresponding to the leading end curvable piece, whereas the third coil at the position corresponding to the trailing end curvable piece. Further, the second coil is placed at a middle position between the leading end curvable piece and the trailing end curvable piece in the curvable portion. With this structure, the accuracy of detecting the shape of the curvable portion can be improved, and the production cost of the system as a whole can be lowered.

Endoscope

An endoscope includes an insertion section inserted into the body cavity and a probe provided inside the insertion section for detecting the form of the endoscope. The probe includes a plurality of coil portions arranged in the longitudinal direction of the insertion section of the endoscope and a wire electrically connecting the coil portions. The coil portions and the wire are covered with a flexible member. And the outer diameter of the covered wire is smaller than the outer diameter of the covered coil portions.
