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.
Claims8
A medical observation device comprising:
- an imaging device configured to capture an observation target;
- a structural support that supports the imaging device 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 structural support, applies power to at least one joint of the plurality of joints, and rotates two of the arms connected at the at least one 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 configured to perform a first control operation that causes the motor to rotate in accordance with the user operation received by the operation receiver and perform a second control operation after the first control operation is completed and rotation of the motor is stopped, wherein
- the controller is further configured to perform the second control operation to rotate the motor in a reverse direction that is opposite to a direction in which the motor is rotated in the first control operation so that a first distance between first tooth surfaces of the two intermeshing gears, the first tooth surfaces meshing with each other in accordance with rotation of the motor in the reverse direction, and a second distance between second tooth surfaces of the two intermeshing 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, are respectively set to values smaller than an amount of backlash between the two intermeshing gears.
