20090299136 | ENDOSCOPIC SYSTEM FOR SURGICAL INSTRUMENT POSITION CONTROL AND POSITION CONTROL METHOD THEREOF - In an endoscopic system, when an affected area of a biomedical tissue in an image is treated with a scalpel and a holding pair of forceps which movably extend from a distal portion of an endoscope through the endoscope while the image taken by the endoscope in a body cavity in a time-series manner is being observed, a treatment is performed in which the holding pair of forceps holds the affected area detached from the biomedical tissue by the scalpel. When any motion is detected in the distal portion of the endoscope included in the image, a motion direction and a motion amount of the distal portion of the endoscope attributed to the motion are detected, and the distal portion of the endoscope is curved to return the scalpel to an original treatment position. | 12-03-2009 |
20090326325 | MULTIJOINTED BENDING MECHANISM AND MULTIJOINTED MEDICAL EQUIPMENT HAVING MULTIJOINTED BENDING MECHANISM - 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. | 12-31-2009 |
20100004508 | MULTIJOINTED BENDING MECHANISM AND MULTIJOINTED MEDICAL EQUIPMENT HAVING MULTIJOINTED BENDING MECHANISM - 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 first wires are disposed inwards of the second wires with respect to a vertical direction of the first and second rotation shafts. | 01-07-2010 |
20100004509 | MULTIJOINTED BENDING MECHANISM AND MULTIJOINTED MEDICAL EQUIPMENT HAVING MULTIJOINTED BENDING MECHANISM - 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 first wires and the second wires are disposed concentrically with respect to a vertical direction of the first rotation shaft and the second rotation shaft. | 01-07-2010 |
20100016666 | SURGICAL INSTRUMENT POSITION CONTROL APPARATUS FOR ENDOSCOPE - An endoscopic system includes a surgical instrument position control apparatus. The surgical instrument position control apparatus estimates motion of an endoscope main body with respect to a target site, based on an image picked up in conjunction with movement of an endoscope. To determine the moving amount of the surgical instrument, the surgical instrument position control apparatus calculates the amounts of operations, such as bending, rotation, and forward and backward movements, of each joint of a surgical arm section which amounts are required to move the surgical instrument from a position taken by the surgical instrument after movement of the endoscope to a surgical procedure position. The surgical instrument position control apparatus thus bends each joint to move the surgical section to the original surgical procedure position so as to hold the position of the surgical instrument every time the endoscope is moved. | 01-21-2010 |
20100022837 | SURGICAL INSTRUMENT AND ENDOSCOPE SURGICAL SYSTEM HAVING SURGICAL INSTRUMENT - A surgical instrument having a surgical unit which operates on an operating portion in a body cavity, an accommodation portion capable of accommodating the surgical unit. The surgical instrument having movement manipulation mechanism connected to the surgical unit for moving the surgical unit to a position at which the surgical unit is accommodated in the accommodation portion and to a position at which the surgical unit is exposed from the accommodation portion along the inside of the accommodation portion. | 01-28-2010 |
20130096423 | ENDOSCOPE SYSTEM - An endoscopic system includes an insertion portion inserted into a tubular body, a ranging mechanism, an insertion path calculation unit and a presentation unit. The insertion portion includes a distal end and a bending portion defining a driving face. The ranging mechanism acquires distance information on the driving face between an inner wall of the tubular body on a far side and the distal end of the insertion portion while the distal end is placed on a near side in the tubular body. The insertion path calculation unit calculates an insertion path for the distal end of the insertion portion extending from the near side on which the distal end is placed, to the far side, based on the distance information. The presentation unit presents the insertion path for the distal end of the insertion portion extending from the near side to the far side. | 04-18-2013 |
20130261392 | TUBULAR INSERTION SYSTEM - A tubular insertion system includes an insertion unit including a bendable portion, a bending operation mechanism that operates the bendable portion. The tubular insertion system further includes a bending operation amount detection/calculation device that calculates bending operation amount information, a bent shape detection/calculation device that calculates bent shape information, and a first operation support information acquisition unit that acquires first operation support information based on at least one of the bending operation amount information and the bent shape information. | 10-03-2013 |
