Master-slave system for moving slave unit based on motion commands inputted into two command input units held by each hand of operator
View Patent ↗There is provided a master-slave system including: a slave unit including an observation optical system imaging a subject A; a treatment part projecting from a surface on which the observation optical system is provided and at least part of the treatment tools is imaged along with the subject A by the observation optical system; a master apparatus including an operating unit held and operated by an operator; a control unit associating operation of the operating unit of the master apparatus with motion of the slave unit and motion of the treatment part; and a monitor screen displaying an image acquired by the observation optical system, wherein the operating unit includes a command input unit into which a motion command for a slave unit is inputted while the operating unit is held by the operator without changing a pose of the operating unit.
1. A master-slave system comprising:
a slave unit including an observation optical system imaging a subject, and a treatment part projecting from a surface on which the observation optical system is provided, at least part of the treatment part being imaged along with the subject by the observation optical system;
a master apparatus including an operating unit held and operated by an operator;
a controller associating operation of the operating unit of the master apparatus with motion of the slave unit and motion of the treatment part; and
a monitor screen displaying an image acquired by the observation optical system, wherein
the operating unit includes a command input unit into which a motion command for the slave unit is inputted while the operating unit is held by the operator without changing a pose of the operating unit,
the operating unit is provided at each of two positions so that each operating unit is held by each hand of the operator,
each operating unit is provided with the command input unit, and
the controller moves the slave unit based on an average value of motion commands inputted into two command input units.
2. The master-slave system according to claim 1 , wherein
the motion command is a rotational motion command, and
the controller associates operation of the operating unit of the master apparatus with rotation around an axial line intersecting the surface of the slave unit and with motion of the treatment part.
3. The master-slave system according to claim 1 , wherein
each of the two command input units is a force sensor that detects a direction of a force applied to a respective operating unit, and
the controller determines a motion direction of the slave unit in accordance with the direction of the force detected by the force sensors.
4. The master-slave system according to claim 1 , wherein each of the two command input units is an input device disposed at a position where the input device is operable with fingers other than the fingers holding the operating unit.
5. The master-slave system according to claim 1 , wherein each of the two command input units is a force sensor in 3 or fewer axial directions.
