A biopsy support device that supports an inspection using a living tissue sampled by a sampling instrument which is used by being inserted into an endoscope having an imaging element, the biopsy support device including a processor configured to recognize that the living tissue has been sampled by the sampling instrument on the basis of captured image data obtained by capturing an image using the imaging element; and generate identification information corresponding to the living tissue in a case where the living tissue is recognized to have been sampled.

An image processing unit includes a shake amount calculation section and a static image-storage control section, and the shake amount calculation section includes a shake amount-calculation processing section and an algorithm switching section. The algorithm switching section applies an algorithm varying for each image, and selects images of which the shake amounts calculated by the shake amount-calculation processing section are small. A first image and a second image, which are selected as the images of which the shake amounts are small, are stored in a static image-storage unit. A display control unit displays static images for storage.

Some of the embodiments of the present disclosure are directed to a dental measurement method comprising: measuring an orientation of a dental measurement device includes a user interface; and displaying information on said user interface based on said orientation.

A system for preventing motion sickness resulting from virtual reality or augmented reality is disclosed herein. In one embodiment, the system includes a virtual reality or augmented reality headset configured to be worn by a user, the virtual reality or augmented reality headset configured to create an artificial environment and/or immersive environment for the user; at least one fluidic lens disposed between an eye of the user and a screen of the virtual reality or augmented reality headset; and a fluid control system operatively coupled to the at least one fluidic lens. In another embodiment, the system includes at least one tunable prism disposed between an eye of the user and a screen of the virtual reality or augmented reality headset, the at least one tunable prism configured to correct a convergence problem associated with the eye of the user.

An endoscope assembly comprising a handle incorporating a liquid reservoir and injection system, a flexible or rigid cannula attaching to the handle, and a distally attached miniature imaging head. The imaging head is a transparent tubular shaped body having an essentially closed proximal end, and a tubular wall extending from the closed proximal end to the distal open end of the body. An optical source is attached to the closed proximal end, and its emitted illumination directed into the tubular wall of the body, such that said illumination is internally reflected within the tubular walls and is emitted from the distal open end. A detector array is disposed within the inner surfaces of the tubular wall section, and a lens images light reflected back into said imaging head, onto the detector array. The optical source is disposed radially inwards of the outer dimensions of the tubular shaped body.

A tubular insertion device includes a tubular device including a flexible tube portion to be inserted into a subject, a sensor which detects a disposition state of the flexible tube portion in the subject, a prediction calculator which calculates next operation information that is information regarding an operation to be performed next by the tubular device, based on the disposition state detected by the sensor and stored data regarding an operation of the tubular device corresponding to each disposition state of the flexible tube portion, and an output circuit which outputs the next operation information calculated by the prediction calculator.

A robot arm controller controlling a treatment tool having a robot arm with an electrically driven joint has a driver configured to drive the treatment tool; a manipulator configured to accept a manipulation input for the treatment tool; and a processor. The processor is configured to: store a position of a distal end portion of the treatment tool as a teaching point when a teaching operation is detected from the manipulator, calculate an interpolation curve passing a plurality of teaching points and an interpolation point on the interpolation curve, control the driver to move the distal end portion of the treatment tool to the interpolation point, and store the position of the distal end portion of the treatment tool as a treatment point when a treatment operation is detected from the manipulator. The interpolation curve is updated so as to pass the plurality of teaching points and the treatment point.

A surgical system for controlling fluid pressure during a surgical procedure is provided. Example systems include an inflow pump coupled to a fluid source and defining an outlet port. An inflow cannula is coupled to the outlet port of the inflow pump and includes a barcode disposed thereon. An endoscope extends from a proximal end to a distal end and includes a shaft. A camera is coupled at the proximal end of the endoscope and provides visualization of a surgical site through the shaft and output a corresponding imagery signal. A pump control unit is coupled to the inflow pump and controls an outlet pressure of the inflow pump. A camera control unit is coupled to the camera and to the pump control unit and receives the imagery signal and decodes the barcode and conveys information indicative of a pressure loss across the inflow cannula to the pump control unit.
