20090012365 | ENDOSCOPE - A driving source unit is detachably coupled to a large-diameter section on a proximal end side of a scope section. When the driving source unit and the large-diameter section are coupled, working shafts of the large-diameter section are engaged with driving shafts of the driving source unit, and the driving shafts linearly move on the basis of a driving force that is generated from driving motor of the driving source unit. One of the working shafts is moved in accordance with the linear movement of the driving shafts. The movement of one of the working shafts, which is moved by the driving shaft, is transmitted via a pinion gear to the other working shaft in a direction opposite to a direction of the movement of the one working shaft. A bend operation wire is pulled by the movement of the working shaft that moves and a bending section is bent. | 01-08-2009 |
20090082621 | Electric Bending Endoscope Apparatus - The present invention has an object to provide an electric bending endoscope apparatus with a configuration which is always capable of securing favorable operability at a time of using an endoscope without placing a weight burden on an operator when operating the endoscope, and for the purpose, the electric bending endoscope apparatus includes at least an electric bending endoscope that is configured by an elongated insertion portion which is inserted into a body cavity, a bending drive section which electrically drives a part of the insertion portion to bend, and an operation portion configured to be separate from the bending drive section and electrically connected to the bending drive section, and performs observation and treatment of an inside of the body cavity, a system controller which is electrically connected to the electric bending endoscope and centrally controls the electric bending endoscope, and an endoscope holding device configured by a bending drive unit which contains the bending drive section and holds a part of the electric bending endoscope, and an arm portion which is connected to the bending drive unit and holds the bending drive unit, and is configured such that by the bending drive unit being attachably and detachably connected to a proximal end side of the insertion portion, the electric bending endoscope and the bending drive section are electrically connected. | 03-26-2009 |

20080200763 | ENDOSCOPE - An endoscope includes an elongated insertion section inserted into a body cavity from a distal end portion, a hard base section provided on a proximal end side of the insertion section, a transmission line, a holding portion, and a connector portion. The transmission line is extended from the inside of the insertion section to the base section and signals or light is transmitted through thereof. The holding portion is disposed in the base section and holds the transmission line while restricting movement of the insertion section and the base section in a direction perpendicular to an axial direction thereof. The connector portion is provided in the base section and connects an end portion of the extended transmission line to an external device through the holding portion. | 08-21-2008 |
20080310912 | ATTACHMENT AND DETACHMENT MECHANISM - An attachment and detachment mechanism includes convex and concave engaging portions provided in first and second couplings respectively and extending in a radial direction of first and second shaft portions, the convex engaging portion is to be slidably inserted into and removed from the concave engaging portion along a longitudinal direction of the concave engaging portion, the convex and concave engaging portions includes basic positions where the longitudinal directions of the convex and concave engaging portions correspond to the attachment and detachment direction of the first and second main body portions and the convex and concave engaging portions are insertable into and removable from each other, and the attachment and detachment mechanism further includes a guide mechanism to guide one engaging portion such that the one engaging portion is disposed at the basic position in conjunction with the attachment or detachment of the first and second main body portions. | 12-18-2008 |
20120078054 | BENDING MECHANISM - A bending mechanism includes a vertical driving portion with a central axis that extends along an X-axis direction, a horizontal driving portion with a central axis that extends along the X-axis direction and is adjacent to the vertical driving portion in a Y-axis direction, a vertical rotary portion that is coupled to the vertical driving portion and is rotated, and a horizontal rotary portion adjacent to the vertical rotary portion in the Y-axis direction that is coupled to the horizontal driving portion and is rotated. The binding mechanism further includes a holding portion holding a vertical operation wire extending from the vertical rotary portion to a rear surface on the side where the horizontal rotary portion is disposed, and holding a horizontal operation wire extending from the horizontal rotary portion to the rear surface on the side of the vertical rotary portion and further intersecting with a vertical operation wire. | 03-29-2012 |
20120277534 | ENDOSCOPE - An endoscope includes a control method input section provided in a bending operation input unit and configured to input a control method of a bending operation, and a control method detector provided in an operation section body and configured to detect the input control method of the bending operation. The endoscope includes an activated portion provided in the bending operation input unit and configured to change its activated state in response to the bending operation in a bending operation input section, an activated state detector provided in the operation section body and configured to detect the activated state of the activated portion, and a drive member provided in the operation section body and configured to be driven in accordance with the detected control method and the detected activated state, thereby bending a bending section. | 11-01-2012 |
