The puncture instrument includes a puncture tip section (2); a first tubular body (3) connected to the puncture tip section (2) at the distal end; and an outer tubular body (5) at least partially covering the first tubular body (3). The first tubular body (3) is formed to be rotatable around an axis along the longitudinal direction. The first tubular body (3) has an outer diameter smaller than an inner diameter of the outer tubular body (5). A drug solution supply path (5a) is provided on the outside of the first tubular body (3).

Abstract: To be capable of efficiently transmitting appropriate information on the motion improvement to a person in motion. A motion evaluation system includes a sensor unit, an information processing device, and an information presentation device. The information processing device includes a communication device, a storage device, and an arithmetic device.

Abstract: To accurately recognize observed objects. An observed-object recognition system includes an observation region estimation portion, an existence region estimation portion, and an object recognition portion. The observation region estimation portion estimates an observation region that is relatively highly likely to be an observation point in at least one first-person image in a first-person video (a video based on the first-person perspective). Based on the observation region, the existence region estimation portion estimates an existence region that belongs to the first-person image and causes an observed object to exist. The object recognition portion recognizes an object in the estimated existence region of the first-person image.

Abstract: A monitor is arranged on the opposite side of a surgery table to a main doctor so that an assistant is able to view a surgery area directly without being blocked by the monitor. A camera has a working distance of more than or equal to 60 cm and is therefore above a view field for the main doctor to view the monitor, so that the visibility of the monitor is not hindered. The working distance is not more than 100 cm so that the resolution of the camera is not lowered too much.

Abstract: The present invention is provided to notify a person who makes a movement of a part to be improved in the movement. A movement evaluation system includes: a proficiency degree estimating unit generating a proficiency degree score on the basis of movement data obtained by detecting a movement of a user; an improvement point extracting unit specifying a part of the movement of the user as an improvement point on the basis of the movement data; and an information generating unit generating suggestion information to be presented to the user, on the basis of the improvement point.

Abstract: A position information server receives position information of a subject from a distance sensor, decides a position information generation process to be executed by the distance sensor on the basis of the received position information, and transmits instruction information related to the position information generation process to the distance sensor.

Abstract: The present invention discloses a posture estimation system including a range image camera for acquiring and outputting range image and an attitude estimation device connected via the network to the range image camera. The range image camera includes a range image sensor, a range image generator that extracts a region including foreground pixels from the input range image acquired from the range image sensor and generates a range image including the extracted area, a first posture estimator that estimates a first joint position from the range image, and a first communicator that transmits the range image and the estimated first joint position.

Abstract: A surgical microscope apparatus includes a stand base to which a stand post is fixed. The stand post supports a stand body so that the stand body horizontally turns around the stand post without turning the stand post. The stand body, therefore, is turnable with small force. Load applied to a rotary part at a top part of the stand post is only the weight of the stand body, and therefore, a bearing of the rotary part can be downsized.

Abstract: A surgical stereoscopic observation apparatus includes an objective optical system having an optical axis and emits two focusing beams in parallel with the optical axis toward the objective optical system. If a focal point of the objective optical system agrees with a surgical field, the two focusing beams converge to a single spot on the surgical field, and if disagrees with the surgical field, form two spots on the surgical field. According to the state of the spots, it is possible to quickly determine with naked eye or on a monitor whether or not the focal point is on the surgical field.

Abstract: The present invention provides a quantification technique of an installation state of a range image camera in a range image camera system provided with a plurality of range image cameras. In the range image camera system provided with the plurality of range image cameras and the range image camera cooperative processing device for cooperatively processing the plurality of range image cameras, the installation information of the range image cameras is generated from a range distribution of the range image photographed by the range cameras and a luminance distribution of the luminance image to photograph the reflected light of the irradiation light of the range image camera arranged adjacently.

Abstract: An image processing device for evaluating a classifier which recognizes a target object within an input image and classifies the target object into one among a plurality of classes, includes: a classification unit which obtains a classification performance of the classifier by using the classifier and classifying the target object included in each of a plurality of verification images in which a class of the target object is known, and outputting one among the plurality of classes for each of the verification images; and an evaluation unit which outputs an evaluation result of the classifier based on the classification performance of the classifier obtained with the classification unit.

Abstract: A stand apparatus for a surgical microscope includes a stand body and a parallel linkage. The parallel linkage is rotatably attached to the stand body by attaching a lower-end joint thereof instead of a vertical intermediate part thereof to the stand body. When the parallel linkage is tilted frontward, no part of the parallel linkage protrudes rearward. Weight balance of the frontward tilted parallel linkage is maintained by, instead of a counterweight, a compression spring arranged along a rear sub-arm.
