The present invention provides a prophylactic or therapeutic agent for dementia, Alzheimer's disease, attention-deficit hyperactivity disorder, schizophrenia, eating disorders, obesity, diabetes, hyperlipidemia, sleep disorders, narcolepsy, sleep apnea syndrome, circadian rhythm disorder, depression, allergic rhinitis or other diseases.A phenylpyrazole derivative represented by formula (1) or a pharmaceutically acceptable salt thereof: {wherein R1 and R2, which may be the same or different, each represent C1-C6 alkyl or C3-C8 cycloalkyl, or R1 and R2 are attached to each other together with their adjacent nitrogen atom to form a 4- to 7-membered saturated heterocyclic ring (wherein said saturated heterocyclic ring may be substituted with halogen or C1-C6 alkyl), n represents an integer of 0 to 2, T represents a hydrogen atom, halogen or C1-C6 alkyl, and R represents formula (I): or the like}.
Abstract:
A robot system for endoscopic treatment includes a gripping unit, a manipulator unit, a treatment instrument drive unit, a gripping force detection unit, a control unit. The gripping unit is inserted into a body cavity along with an endoscopic apparatus and grips desired living tissue using gripping members. The manipulator unit includes a multi-joint structure that enables bending and stretching. The treatment instrument drive unit pulls and pays out wires. The gripping force detection unit detects gripping force provided by the gripping members. The control unit instructs the treatment instrument drive unit to pull and pay out the wires for the gripping operation so that the gripping force detected by the gripping force detection unit falls within a predetermined range when the gripping unit in the gripping state moves.

Abstract:
A multijointed bending mechanism having a first bending piece, a second bending piece connected to the first bending piece so as to be rotatable around a first rotation shaft, a third bending piece connected to the second bending piece so as to be rotatable around a second rotation shaft, at least two first wires connected to the first bending piece to rotate the first bending piece and at least two second wires connected to the second bending piece to rotate the second bending piece. The second wires are disposed inwards of the first wires with respect to a vertical direction of the first and second rotation shafts.
Abstract:
An endoscopic therapeutic device includes an elongated insertion section which is inserted into a living body through a therapeutic device channel of an endoscope, a tubular puncture needle which is disposed at a distal end portion of the insertion section and is made to pierce a living body tissue, a syringe for sampling the living body tissue in a state in which the puncture needle pierces the living body tissue, and a freezing device for subjecting the living body tissue, which is collected by the syringe, to a process for analysis.
Abstract:
A multijoint manipulator apparatus includes a tubular-member, linear-motion-transmission-members, a drive-unit, a position-detector, a tension-detector, an operation-unit, and a movement-degree-calculation-unit. The linear-members are inserted in the tubular-member, one end and the other end of each of the linear-members being fixed to the vicinity of a joint of the tubular-member and the drive-unit, respectively. The drive-unit moves the linear-members. The position-detector and the tension-detector detect positions and tension of the linear-members, respectively. A desired position/posture of a point of interest is input to the operation-unit. The calculation-unit calculates a current position/posture of the point, a weighting factor serving to give priority to and move the linear-members the tension of which is relatively low among the linear-members, and movement degrees of the linear-members to move the point to the desired position/posture, and causes the drive-unit to pull the linear-members.
Abstract:
An endoscope bending control apparatus includes: an image feature value calculating section for calculating, based on an endoscopic image, an image feature value related to a luminal dark part; a bending control section for performing bending control on a bending portion in either one of a first bending operation mode in which a position of the luminal dark part is set as an insertion target and a distal end of the insertion portion is directed to the position and a second bending operation mode in which the distal end of the insertion portion is directed in a direction of the position of the luminal dark part; an operation mode switching section for switching an operation mode from one bending operation mode to the other according to a first switching condition based on the calculated image feature value; and a switching condition changing section for changing the first switching condition.
