Errors in a blended stream that would result in non-display or obscuring of a live video stream from a medical device may be automatically detected, and a failover stream corresponding to the first live video stream may be displayed to medical personnel. For example, one or more second input streams that are being blended may contain no data or invalid data which may result in the blended stream not displaying (or obscuring) the live video stream (if the blended were displayed). Switching from blending to a failover buffer may occur within the time to process a single video image frame. Upon detection (prior to display) that the blended stream would not display the live video stream, display of the live video stream from the failover buffer may be initiated. Other aspects are also described and claimed.

Various embodiments are directed to battery packs for use with surgical instruments. The battery packs may comprise a plurality of cells and at least a portion of the plurality of cells may not be electrically connected to one another. The battery packs may comprise a switch or other mechanism for interconnecting the plurality of cells and may also comprise, or be used in conjunction with, a discharge switch or plug configured to electrically connect an anode of the battery pack to a cathode of the battery pack, for example, via a resistive element.

A catheter, comprising: a flexible tubular member having at least one lumen therethrough and a proximal end and a distal end; a plurality of conductive cables extending through at least one of the at least one lumen; and at least one electrically operated component, attached at the distal end and powered by at least one electrical current driven on at least one of the plurality of conductive cables. Some of the plurality of conductive cables are attached to the distal end such that the flexible tubular member is deformed by exerting at the proximal end a tensile force on one of the some of the plurality of conductive cables and a compressive force on another of the some of the plurality of conductive cables, while the at least one electrical current is driven on the some of the plurality of conductive cables.

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 bronchoscope has a handle with a suction port and a flexible scope port. A carrier tube extends from the handle and has first and second passageways. The first passageway communicates with the suction port and the second passageway communicates with the flexible scope port. A flexible scope assembly is insertable into the second passageway of the carrier tube. The flexible scope assembly includes a camera wire with a camera on one end and a transmission connector on an opposite end. The flexible scope assembly has a sheath extending around the camera wire that seals the camera wire and the transmission connector and the camera wire and the camera. The camera includes an imaging device and lighting elements. The flexible scope assembly is removably connectable to the handle at the flexible scope port. The flexible scope assembly may be sanitized when removed from the handle.

An endoscope power supply system includes an endoscope including an imaging unit that images an object, a housing apparatus to which the endoscope is detachably connected, a plurality of power source units that are provided in the housing apparatus and configured to output electric power different from one another, switches each provided in an output stage of each of the power source units of the housing apparatus and formed of two FETs that are back-to-back connected, and a controller that is provided in the housing apparatus, selects a power source unit necessary to operate the endoscope from the power source units, and controls the switches to output electric power generated by the selected power source unit to the endoscope.

A control section outputs a control signal. An actuator is connected to a drive section and operates based on the control signal. An operation information acquisition section acquires operation information related to an operation status of the actuator. A storage section stores correction information included in control information which includes a relationship between an operation status and the control signal. The correction section determines whether or not the control signal and the operation status are consistent with the control information, and when inconsistent, corrects correction information for consistency.

A hybrid detection apparatus including a detection device and a functional circuit is provided. The detection device is configured to execute a first detection function, so as to obtain first detection information. The functional circuit is suitable to be removably connected to the detection device. When the functional circuit is connected to the detection device, the detection device controls the functional circuit for performing a second detection function, so as to obtain second detection information. One of the first and the second detection functions is an image capturing function, and another one of the first and the second detection functions is a temperature detection function.

An endoscope system includes: a scope that has an imaging sensor; a frame that houses a portable information terminal; and an interface adapter that converts an imaging signal obtained by the imaging sensor into image data displayable by the portable information terminal and sends the image data to the portable information terminal, and the interface adapter is fixed to the frame.

A power supply control system includes a power supply circuit that supplies power, an electronic component that is operable by the power supplied from the power supply circuit, starts shutdown processing in response to an input of a stop instruction signal, and operates when an operation instruction signal is input, and a signal control circuit that receives a power input state signal or a power cutoff state signal as a power state signal indicating a state of the power supply circuit, outputs the stop instruction signal when the power cutoff state signal is input, outputs the operation instruction signal when the power input state signal is input, and outputs the stop instruction signal at least during the shutdown processing when the power input state signal is input in a case in which the shutdown processing of the electronic component is not finished.
