Abstract
A medical observation device includes: an imaging device; a support unit that supports the image-capturing unit and includes arms and joints rotatably connecting the arms; a motor that applies power to at least one of the joints, and rotates two of the arms connected at the joint relative to each other; a gear mechanism that includes two intermeshing gears and is disposed in a power transmission path from the motor to the at least one joint; an operation receiver that receives a user operation; and a controller that performs first control for causing the motor to rotate in accordance with the user operation received by the operation receiver and performs second control after the first control is completed and rotation of the motor is stopped.
Claims7
A medical observation device comprising:
- an imaging device configured to magnify an observation target and image the magnified observation target;
- a support unit that supports the image-capturing unit at a distal end and includes a plurality of arms and a plurality of joints rotatably connecting the arms;
- a motor that is provided in the support unit, applies power to at least one of the joints, and rotates two of the arms connected at the joint relative to each other;
- a gear mechanism that includes two intermeshing gears and is disposed in a power transmission path from the motor to the at least one joint;
- an operation receiver that receives a user operation;
- and
- a controller that performs first control for causing the motor to rotate in accordance with the user operation received by the operation receiver and performs second control after the first control is completed and rotation of the motor is stopped, wherein
- the controller performs the second control to rotate the motor in a reverse direction that is opposite to a direction in which the motor is rotated in the first control, and to adjust a first distance between first tooth surfaces of the two gears, the first tooth surfaces meshing with each other in accordance with rotation of the motor in the reverse direction, and adjust a second distance between second tooth surfaces of the two gears, the second tooth surfaces being out of meshing engagement with each other in accordance with the rotation of the motor in the reverse direction, to a smaller value than an amount of backlash between the two gears.
