This disclosure relates to instruments and methods of performing an endoscopy. An endoscope for producing images of a surgery in vivo may include a hub and an imaging rod extending from the hub, the imaging rod being configured to receive light and direct the light to an imaging sensor located adjacent to a distal end of the imaging rod, the hub and the imaging rod being attached to form an assembly having a center of mass established distally of the hub. In other implementations, the hub may be omitted.

A control device includes: a power source configured to supply a predetermined power-supply voltage to an imaging element; a voltage detector configured to detect an output voltage value of the power-supply voltage supplied by the power source; and a processor comprising hardware, the processor being configured to supply an adjusted voltage value from the power source to the imaging element based on a voltage value of the power-supply voltage detected in the imaging element and on the output voltage value detected by the voltage detector, calculate a delay time from timing when the voltage value of the power-supply voltage is detected in the imaging element until timing when the power source supplies the adjusted voltage value to the imaging element, and control supply timing when the power source supplies the adjusted voltage value based on the delay time.

An instrument drive system configured to attach to an instrument channel of an endoscope assembly and manage a relative feed position of an instrument using two drive wheels and a device application in a controller. The instrument drive system is attached directly to the instrument channel of the endoscope assembly. operation of the instrument drive system is proximate to the endoscope assembly and an inputs-controls and a deflection control thereof.

An endoscope system includes at least any one of a processor device that is attachable to and detachable from an endoscope or a light source device that is attachable to and detachable from the endoscope. In a case where the endoscope is mounted on the processor device or the light source device, the processor device or the light source device performs a request sequence in which a request signal, for requesting a start of execution of encoding processing with respect to digital image signals, is transmitted to the endoscope.

A system includes an endoscope connector and an endoscope adapter. The endoscope connector includes a first portion. The first portion includes a first magnetic coupling element and a first planar portion that is perpendicular to an axial direction of the endoscope connector. The endoscope adapter includes a second planar portion. The second planar portion includes a second magnetic coupling element and a substantially planar surface that is perpendicular to an axial direction of the endoscope adapter. The endoscope connector is non-mechanically attachable to the endoscope adapter using the first magnetic coupling element and the second magnetic coupling element. The first planar portion is alignable with the second planar portion such that: electroconductive contacts of the endoscope connector are axially aligned with electroconductive pins of the endoscope adapter and a port of the endoscope connector is axially aligned with a corresponding insertion port of the endoscope adapter.

A method performed by a video controller. The method receives a first video stream captured by an endoscope of a surgical system, and receives a second video stream that comprises surgical data. The method displays the second video stream superimposed above an area of the first video stream, and determines that the second video stream is to cease being superimposed. Responsive to determining that the second video stream is to cease being superimposed, the method continues to display the first video stream.
