  • Publication number: 20190261841
    Abstract: There is provided a medical control apparatus including: a display control section configured to control a display of a medical captured image captured by an imaging device on the basis of a state related to a movement of the imaging device. In a case in which the state related to the movement of the imaging device is a first state in which the imaging device is immovable, the display control section causes the medical captured image to be displayed on a display screen, and in a case in which the state related to the movement of the imaging device is a second state in which the imaging device is movable, the display control section causes a medical still image to be displayed on the display screen, and changes a display of the display screen according to the movement of the imaging device.

  • Publication number: 20190015175
    Abstract: A medical observation apparatus (10) includes an imaging section (140), an arm section (110), and a control section (210). The imaging section (140) captures an observation target. The arm section (110) includes multiple links and joint sections (130) that join the links to each other, and supports the imaging section (140). The control section (210) controls a torque that drives the joint sections (130). When a surgeon imparts an external force to the arm section (110) or the imaging section (140), a torque (external torque) due to the external force acts on the joint sections (130). When a torque detection section (134) of the joint sections (130) detects the external torque, the control section (210) outputs a torque command value (?) such that a joint driving section (131) produces a torque in the same direction as the external torque. The torque command value (?) includes a component that cancels out a torque that a cable (495) twisted inside the joint sections (130) produces due to a restoring force.
