20100234873 | DRIVE DEVICE, AND MEDICAL APPARATUS AND TRAINING APPARATUS INCLUDING THE SAME - A drive device for driving a linear body having flexibility includes a first roller, a motor for feeding the linear body in a direction of extension of the linear body by directly transmitting rotation force to the first roller to rotate the first roller, a motor drive portion for driving the motor by supplying a current to the motor, and a control unit for calculating force applied to the linear body in the direction of extension based on the current supplied to the motor. | 09-16-2010 |
20100292566 | LOAD DETECTION DEVICE AND LOAD DETECTION METHOD - According to this load detection method, load (Fi) in insertion of a linear body having flexibility in an inlet of a hollow tube inserted in a bending vessel in a body is detected, an image of the hollow tube or the linear body is taken, a degree of bending of the hollow tube or the linear body is detected based on the image, and load (Fo) at a tip end of the linear body is calculated based on the detected insertion load (Fi) and the degree of bending. Therefore, the load (Fo) at the tip end of the thin linear body can readily be detected. | 11-18-2010 |
20110046553 | DRIVE DEVICE FOR LINEAR BODY - There is provided a drive device for a linear body, that allows a treatment to be immediately, manually resumed when an emergency arises. A drive device for a linear body includes a securing portion capable of securing a Y connector having a through hole, and an actuator including a driving roller and a driven roller moving the linear body that is inserted in the through hole of the Y connector in the longitudinal direction of the linear body. The drive device allows the linear body and the Y connector to be integrally, manually attached to and detached from the securing portion. | 02-24-2011 |
20110077681 | INSERTION DEVICE AND INSERTION METHOD OF COIL - An insertion device of a coil includes a delivery wire driving unit, a secondary catheter driving unit, and a control circuit. A platinum coil for coil embolization is attached to the tip of a delivery wire. The delivery wire driving unit is provided in the proximity of the entrance of a Y connector such that the delivery wire is advanced and moved back. The secondary catheter driving unit is provided in the proximity of the entrance of a Y connector such that the secondary catheter is advanced and moved back. The control circuit controls the delivery wire driving unit so as to insert the delivery wire by a predetermined insertion force. If the delivery wire cannot be inserted, the control circuit controls the secondary catheter driving unit such that the secondary catheter is advanced after being moved back, and then controls the delivery wire driving unit so as to insert the delivery wire. | 03-31-2011 |
20110179894 | REMOTE-CONTROLLED ACTUATOR - A remote controlled actuator includes a spindle guide section of an elongated configuration, a distal end member fitted to a tip end of the spindle guide section for alteration in attitude, and a drive unit housing to which a base end of the spindle guide section is connected. The distal end member rotatably supports a spindle then holding a tool. The spindle guide section includes a hollow outer shell pipe, a rotary shaft and a guide pipe, and an attitude altering member for altering an attitude of the distal end member is inserted within the guide pipe. A hollow of the outer shell pipe includes a round hole portion at a center and a grooved portion depressed radially outwardly from the round hole portion. The rotary shaft is arranged within the round hole portion whereas the guide pipe is arranged within the grooved portion. | 07-28-2011 |
20110203825 | REMOTE-CONTROLLED ACTUATOR - A remote controlled actuator includes an elongated spindle guide section and a distal end member fitted to a distal end thereof for alteration in attitude. The distal end member rotatably supports a spindle for holding a tool. The spindle guide section includes a rotary shaft for transmitting rotation of a tool rotation drive source to the spindle. An attitude altering member inserted in a guide hole is selectively advanced or retracted by an attitude control drive source. An initial attitude hold control unit controls the attitude control drive source so that an initial attitude holding force necessary to maintain the distal end member in the initial attitude can be applied to the attitude altering member. An attitude alteration control unit controls the attitude control drive source so that the attitude of the distal end member can be altered by a force larger than the initial attitude holding force. | 08-25-2011 |
20110230868 | REMOTE-CONTROLLED ACTUATOR - A remote-controlled actuator includes a spindle guide section of an elongated shape, a distal end member fitted to a distal end of the spindle guide section for alteration in attitude and rotatably supporting a tool, and a drive unit housing having a base end of the spindle guide section connected therewith. A rotary shaft for transmitting rotation of a tool rotation drive source within the drive unit housing to the tool and an attitude altering member for altering the attitude of the distal end member by the drive of an attitude altering drive source within the drive unit housing are accommodated within the spindle guide section. A cutting force estimator is provided for estimating the magnitude of at least one component force of a principle force, a radial force and a feed force in a cutting force which the tool applies to a work to be processed. | 09-22-2011 |
