摘要:
A link actuation device (51) includes a distal end side link hub (3) connected with a proximal end side link hub (2) through three or more sets of link mechanisms (4) for alteration in orientation. By means of an actuator (53) provided in the two or more set of the link mechanism (4), the distal end orientation, which is the orientation of the distal end side link hub (3) relative to the proximal end link hub (2), is changed arbitrarily. The operating device (55) includes an orientation designating unit (55a) for designating the distal end orientation aimed at by means of a coordinate position on the orthogonal coordinate system by an artificial manipulation, an orientation acquiring unit (55) for acquiring the distal end orientation that is expressed by an angular coordinate system through calculation, and an orientation information applying unit (55c) for applying information on the distal end orientation so acquired to a control device (54) for controlling the actuator (53).
摘要:
A remote controlled actuator includes an elongated spindle guide section (3), a distal end member (2) fitted to the distal end thereof for alteration in attitude, and a drive unit housing (4a) connected with a base end of the spindle guide section (3). The distal end member (2) rotatably support a spindle (13) holding a tool (1). The spindle guide section (3) includes a rotary shaft (22) for transmitting a rotation of the spindle (13) and an attitude altering member (31) for altering the attitude of the distal end member (2) both within an outer shell pipe (25) forming an outer shell. The attitude altering member (31) is reciprocally movably inserted in a guide pipe (30) within the outer shell pipe (25). A guide pipe restraining unit (50) is provided for restraining the guide pipe (30) from moving within the outer shell pipe (25).

An insertion device of a coil includes a delivery wire driving unit (10), a secondary catheter driving unit (20), and a control circuit (30). A platinum coil (100) for coil embolization is attached to the tip of a delivery wire (110). The delivery wire driving unit (10) is provided in the proximity of the entrance of a Y connector (131) such that the delivery wire (110) is advanced and moved back. The secondary catheter driving unit (20) is provided in the proximity of the entrance of a Y connector (132) such that the secondary catheter (124) is advanced and moved back. The control circuit (30) controls the delivery wire driving unit (10) so as to insert the delivery wire (110) by a predetermined insertion force. If the delivery wire (110) cannot be inserted, the control circuit (30) controls the secondary catheter driving unit (20) such that the secondary catheter (124) is advanced after being moved back, and then controls the delivery wire driving unit (10) so as to insert the delivery wire (110).
摘要:
A control device is provided which is operable to change the position of a distal end side link hub by driving each of arms, which are proximal end side links of a plurality of link mechanisms by means of an actuator. When in a series of operations, the position change of the distal end side link hub is mad by an angle greater than a predetermined angle, a relay position setting unit is provided for setting a relay point between a starting point and a terminating point of each of the arms so that the interference of the three axis arms may be relieved. A position change control unit performs a position control so as to pass simultaneously through the relay point so set.
摘要:
A remote controlled actuator assembly includes an elongated guide section (3), a distal end member (2) fitted to the guide section (3) for alteration in attitude, and an operating tool (1) retained by the distal end member (2). An attitude altering member (31) within the guide section (3) is reciprocally movably inserted by an attitude altering drive source (43) to alter the attitude of the distal end member (2). The attitude altering drive source (43) is controlled by an attitude altering controller (63). An attitude detection unit (9) detects the attitude of the distal end member (2) relative to the guide section (3). A calibrator (65), by use of the attitude information detected by the attitude detection unit (9), corrects or generates a command value which the attitude altering controller (63) outputs to the attitude altering drive source (43).

A remote controlled actuator (5) includes an actuator main body (10), a distal end member (2) fitted to a distal end of a spindle guide section (3) of the actuator main body (10) for alteration in attitude, and a tool (1) rotatably supported by the distal end member (2). The navigation system includes a tool processing member position estimator (55) for estimating the position of a processing member (1a) of the tool (1) from information on the position and attitude of a marker (7A), fitted to the actuator main body (10), that are detected by a marker detecting unit (8), information on the attitude of the distal end member (2) relative to the actuator main body (10), information on the relative position of the distal end member (2) relative to the marker (7A), and information on the shape of the tool (1).
