The operation portion includes a correction algorithm calculating portion in which the output range of instruction signal of the joystick is converted to coincide with the predetermined output range of the bending instruction portion instruction-signal being the operation signal outputted by the operation portion according to the joystick being the bending instruction portion to be fitted to the operation portion, to generate the bending instruction portion operation-signal. | 10-23-2008 |
| 20080281158 | MEDICAL APPARATUS - A medical apparatus includes a power unit serving as a first connector portion, an insertion-section-side body serving as a second connector portion having an electrical contact portion which is to be connected to the power unit, a first wiper serving as a removing member which removes moisture on the electrical contact portion in a predetermined direction when the power unit and the insertion-section-side body are connected, and a second wiper serving as a prevention member which prevents entrance of moisture from a direction which is different from the direction of moisture removal by the first wiper. Thereby, even if moisture adheres to the electrical contact portion, the moisture is removed in the process of connecting the connection section, there is no concern that the moisture that is removed adheres to the electrical contact portion again, and the reliability can be improved. | 11-13-2008 |
| 20090048488 | ENDOSCOPE - There is provided an endoscope capable of obtaining operability for changing a shape of a bending portion and improving responsiveness. | 02-19-2009 |
| 20090149711 | ENDOSCOPE SYSTEM - An endoscope system includes an endoscope with a bending portion installed on a distal side of an insertion portion; a bending drive unit which drives and bends the bending portion electrically; a map information storage unit which stores map information digitized by associating an amount of bending and a corresponding three-dimensional position and direction of a distal end of the insertion portion with each other, with a position near a rear end of the bending portion being designated as a reference position; a position and direction detecting unit which detects the position and direction of the distal end of the insertion portion; and a bending control unit which controls the bending drive unit to orient the distal end of the insertion portion into a target direction using the map information. | 06-11-2009 |
| 20090287055 | Electric bending operation device and medical treatment system including electric bending operation device - An electric bending operation device can be mounted to an insertion portion of a medical instrument for observation including an electric bending portion. The electric bending operation device includes: an insertion portion mounting mechanism; a rotation mechanism; an insertion portion operation section; and a support column. The insertion portion mounting mechanism includes a pressing portion that is provided integrally with a rotary cylinder through which the insertion portion is passed and presses and holds the insertion portion. Switching can be performed between a state where the pressing portion presses the insertion portion and the rotary cylinder is integral with the insertion portion and a state where the insertion portion is advanced or retracted with respect to the rotary cylinder. The rotation mechanism is provided in the insertion portion mounting mechanism. The rotation mechanism rotates the rotary cylinder to rotate the insertion portion around an axis thereof when the rotary cylinder is integral with the insertion portion. The insertion portion operation section includes a bending portion operation section and a twisting operation portion. The bending portion operation section performs bending operation of the electric bending portion provided in the insertion portion. The twisting operation portion rotates the rotary cylinder to rotate the insertion portion. The support column integrally connects the insertion portion operation section and the insertion portion mounting mechanism. | 11-19-2009 |
