Abstract

A single-use or reusable cap or an objective head to a scope can be used for integrating a laser fiber within the objective head but outside a working channel of the scope. The endoscope maintains an attached or embedded permanent laser fiber to ablate particulates that are suctioned into the endoscope assembly via a suction conduit. With such integration, there is no need to manipulate the laser fiber into a working channel; rather, a practitioner, e.g., physician, can move the medical device, including the laser fiber, as an entire unit into the patient toward the target stone and allow for suction of the stone through a working channel without blocking of the working channel by the laser fiber.

Abstract

This explanation support device includes a specification unit and an explanation basis acquisition unit. The specification unit receives, with respect to a first image, a first identification result and a first certainty factor output by a black-box type first inference engine, and, with respect to the first image, a second identification result and a second certainty factor output by a white-box type second inference engine. Furthermore, the specification unit receives at least one identification result and certainty factor from among the following: a third identification result and a third certainty factor output by a white-box type third inference engine different from the second inference engine, with respect to the first image; a fourth identification result and a fourth certainty factor output by the second inference engine, with respect to a second image separated by a predetermined number of frames from the first image; and a fifth identification result and a fifth certainty factor output by the second inference engine, with respect to a third image obtained by processing the first image. The specification unit identifies, from the certainty factors other than the received first certainty factor, a certainty factor closest to the first certainty factor, among the certainty factors associated with the same identification result as the first identification result. The explanation basis acquisition unit acquires identification basis information associated with the identified certainty factor and outputs the identification basis information to a monitor.

Abstract

A system for determining one or more procedure locations during an endoscopic medical procedure may comprise processing circuitry and memory with instructions stored thereon that when performed by the processing circuitry cause the processing circuitry to receive an input corresponding to the endoscopic medical procedure. The input may include an endoscopic video stream, a patient history, one or more organizational guidelines, or a current position of the endoscope in the anatomy of the patient. The processing circuitry may determine, based on the input one or more procedure locations in association with a map of a portion of the anatomy of the patient and display the map on a graphical user interface. The processing circuitry may further display graphical elements that indicate the one or more procedure locations on the displayed map and dynamically update the graphical elements during the endoscopic medical procedure to indicate whether the one or more procedure locations correspond to one of a completed or uncompleted procedure there.

Abstract

Provided are a medical assistance device, a medical assistance method, and a program that allow the temporal relationship between continuous information and discrete information to be identified. The medical assistance device comprises a processor. The processor: acquires examination data including at least one of endoscopic examination and treatment, the examination data including continuous information of one or more continuous states continuous in time on the same time axis from the start to the end of examination, and one or more pieces of discrete information on the same time axis; generates, on the basis of the examination data, chart information including the time axis from the start to the end of examination, continuous region information, and discrete region information, the continuous region information indicating a change in the continuous state of examination on the same time axis in a manner indicating continuity from the examination start time to a change start time and from the change start time to a change end time or a next change start time, and the discrete region information indicating the time of generation of the discrete information; and outputs the chart information.

Abstract

A needle holder includes a sheath, a grasper capable of grasping a target object, an operation portion capable of opening and closing the grasper, and an operation wire. The operation portion includes a main body, a slider, and an elastic member that is elastically deformable depending on an opening and closing position of the grasper. The slider is connected to the grasper via the operation wire. The grasper can release grasping of the target object and can grasp the target object with a first grasping force in response to an operation of moving the slider against a restoring force of the elastic member. The grasper can grasp the target object with a second grasping force smaller than the first grasping force when the restoring force of the elastic member and tension of the operation wire are balanced.

Abstract

An endoscope system includes a gas feeding apparatus that feeds carbon dioxide, and a light source apparatus provided with an air pump for supplying air. The endoscope system feeds the carbon dioxide or the air from a distal end of an endoscope when a gas/liquid feeding button provided to the endoscope is operated. The endoscope system includes a pressure meter and a processor. The pressure meter is provided inside the gas feeding apparatus and configured to detect a pressure of the carbon dioxide. The processor is configured to perform control for stopping feeding of the air by the air pump when determining that, after the carbon dioxide is fed by an operation of the gas/liquid feeding button, the pressure of the carbon dioxide detected by the pressure meter reaches a predetermined threshold.
