Abstract:
A medical observation system includes a multi-link structure in which a plurality of links is mutually coupled by joint parts, a medical observation apparatus attached on the multi-link structure, a control part configured to control the multi-link structure or the medical observation apparatus, and a user interface part by which a user inputs an instruction to change a visual field of the medical observation apparatus. When a user instructs to move a visual field of the medical observation apparatus vertically or horizontally, to rotate an oblique-viewing endoscope, or to change a magnification of the visual field via the user interface part, the control part controls the multi-link structure or the medical observation apparatus.
Abstract:
This specification discloses an excellent communication device of a field coupling type that increases field coupling efficiency between electrodes and realizes a small-sized device. This specification also discloses a communication system and an electrode. A communication device 100 includes: a first resonant circuit 121 connected in series to an electrode unit 110 formed with two conductor plates; and a second resonant circuit 122 connected in parallel to the electrode unit 110 and the first resonant circuit 121, which are connected in series. The constant of a resonant circuit is determined so that the voltage V2 to be applied to the electrode unit 110 becomes higher than the voltage V1 to be applied to the electrode unit 110 and the first resonant circuit 121 connected in series. In this manner, a field coupling electrode that has a very high coupling strength at a target frequency is obtained.

Abstract:
[Problem] To prevent sight of an observation target from being lost from a visual field of a monitor. [Solution] A surgical arm system includes: an articulated arm in which a plurality of joints is rotatably connected by a plurality of links and which is capable of supporting an oblique-viewing endoscope at a tip; and a control system which controls the articulated arm to change a position and a posture of the oblique-viewing endoscope. The control system controls at least one of a rotation speed and a movement speed of the oblique-viewing endoscope in a visual field imaged through the oblique-viewing endoscope based on a position of the observation target in the visual field.

A surgical imaging system including a surgical imaging device including identification information; a holding arm that holds and controls a position of the imaging device; a user interface configured to provide non-contact operation of the holding arm; and processing circuitry configured to control the holding arm according to the identification information and an output of the user interface.
Abstract:
A pointing device includes a casing, a tactile sense presentation section, and a sensor section. The sensor section detects an operation for the casing and outputs an operation signal for controlling a movement of a pointer on a screen. The control apparatus includes an area setting section and a signal generation section. The area setting section sets a first area that belongs to an inside of a display area of an object on the screen, a second area that belongs to an outside of the display area of the object, and a third area that belongs to a boundary portion between the first area and the second area. The signal generation section calculates a position of the pointer based on the operation signal to generate, when the pointer is located in the first area, a control signal by which the tactile sense presentation section is driven in a first drive mode and generates, when the pointer is located in the third area, a control signal by which the tactile sense presentation section is driven in a second drive mode.

Abstract:
The present technology relates to a control device, a control method, and a surgical system that enable an operator to implement operation without a burden. A control unit controls a plurality of patterns of operations of a surgical instrument, and an acquisition unit obtains motion information indicating a motion of a user. Furthermore, the control unit controls the operations of the respective patterns corresponding to the motion information obtained by the acquisition unit in parallel using only a single operation performed by the user as a trigger. The present technology can be applied to a control device of a surgical system.
