A flexible tube insertion apparatus includes a flexible tube having flexibility and configured to be inserted into an object to be inserted, one or more external force detectors disposed on the flexible tube and configured to detect a force of an external force applied to the flexible tube when the flexible tube is twisted in at least one direction, and a providing device configured to provide twisting information regarding a twisting direction of the flexible tube for releasing a loop section formed in the flexible tube, according to a direction in which the flexible tube is twisted and the detected force of the external force.

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 endoscopic examination supporting apparatus includes at least one processor including hardware. The processor acquires insertion shape information indicating an insertion shape of an insertion section of an endoscope inserted into a subject, evaluates, based on the insertion shape information, a procedure including inserting operation for the insertion section performed by a user who operates the endoscope during an endoscopic examination, and generates procedure evaluation information.

An image processing apparatus includes a processor including hardware, the processor being configured to: determine whether or not an overlapping portion is present in imaging areas included in a plurality of images captured by a plurality of imagers, respectively, the plurality of imagers being are inserted into a subject to capture images of an observation target at different positions from each other; determine whether or not each of the plurality of imagers is inserted to a focal point position at which the observation target is in focus; and generate a composite image that is composed of the plurality of images when it is determined that each of the plurality of imagers is inserted to the focal point position and that the overlapping portion is present in the imaging areas.

The present disclosure relates to computer-implemented systems and methods for detecting a feature-of-interest in a video. In one implementation, a computer-implemented system may include a discriminator network and a generative network. The discriminator network may include a perception branch and an adversarial branch, the perception branch being configured to output detections of the feature-of-interest in the video. The generative network may be configured to receive detections of the feature-of-interest from the perception branch of the discriminator network and generate artificial representations of the feature-of-interest based on the detections from the perception branch. Further, the adversarial branch may be configured to provide an output identifying differences between the false representations and true representations of the feature-of-interest, and the perception branch may be further configured to be trained by the output of the adversarial branch so that false representations are not detected by the perception branch as true representations.

Surgical systems are provided. In one exemplary embodiment, a surgical system includes a first scope device having a first portion within an extraluminal space and a second portion positioned within an intraluminal space. The first scope device transmits image data of a first scene. A second scope device is disposed within the extraluminal space and transmits image data of a second scene. The first portion of the first instrument is present within the field of view of the second scope device to track the first scope device relative to the second scope device. A controller receives the transmitted image data of the first and second scenes, to determine a relative distance from the first scope device to the second scope device within the extraluminal space, and to provide a merged image. At least one of the first and second scope device in the merged image is a representative depiction thereof.

Systems, devices, and methods for controlling cooperative surgical instruments are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common body cavity of a patient from different approaches to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of surgical tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and operate in concert with one another to effect a desired surgical treatment.

In general, devices, systems, and methods for multi-source imaging are provided.

Systems, devices, and methods for controlling cooperative surgical instruments with variable surgical site access trajectories are provided. Various aspects of the present disclosure provide for coordinated operation of surgical instruments accessing a common surgical site from different approach and/or separate body cavities to achieve a common surgical purpose. For example, various methods, devices, and systems disclosed herein can enable the coordinated treatment of tissue by disparate minimally invasive surgical systems that approach the tissue from varying anatomical spaces and must operate differently, but in concert with one another, to effect a desired surgical treatment.

An endoscope processor device generates first video signals. A recognition processing processor device generates second video signals by reflecting a result of recognition processing based on the first video signals. A display displays any one of the second video signals or the first video signals switched from the second video signals on the basis of first video switching signals from the recognition processing processor device. The display displays that a result display of the recognition processing is being stopped in a case where the result display of the recognition processing by the second video signals is stopped.
