A keypad includes a support, a snap disk on a first side of the support transformable from a released state to a loaded state, a cover forming a seal over the first side, a pocket in the cover, a magnet and a plunger disposed in the pocket, the plunger adapted to engage and transform the snap disk to the loaded state, a magnetic field sensor on a second side of the support, the second side opposite the first side and logic circuitry adapted to obtain a value of a strength of a magnetic field from the sensor, compare the value against a predetermined threshold value that corresponds at least approximately to the strength of a magnetic field, and when the plunger has transformed the snap disk to the loaded state and the value reaches or exceeds the threshold value, output a signal indicating that a key press occurred.

Hyperspectral videostroboscopy imaging is described. A system includes an emitter for emitting pulses of electromagnetic radiation and an image sensor comprising a pixel array for sensing reflected electromagnetic radiation. The system includes a controller configured to cause the emitter to emit the pulses of electromagnetic radiation at a strobing frequency determined based on a vibration frequency of vocal cords of a user. The system is such that at least a portion of the pulses of electromagnetic radiation emitted by the emitter comprises electromagnetic radiation having a wavelength from about 513 nm to about 545 nm, from about 565 nm to about 585 nm, or from about 900 nm to about 1000 nm.

An endoscope body of an endoscope can include a handle, a shaft extending distally from the handle, and a distal portion at a distal end of the shaft. The handle can include a light guide that can receive illumination from a light source that is separate from the endoscope body. The light guide can include an illumination splitter that can split the received illumination into a target illumination and a handle illumination. The light guide can propagate the target illumination to the distal portion to illuminate a target. The distal portion can optionally include a camera that can capture an image of the illuminated target. The illumination splitter can propagate the handle illumination to illuminate at least a portion of the handle, such as an instrument port that can provide access to a proximal end of an instrument sheath that extends to the distal portion.

An external mechanism for endoscope includes a bending wheel, a motor, a housing case, a case detachably fixing member, and a mounting restricting member obstructing mounting of a housing case on a sub operation section by interfering with a second bending upward and downward fixing lever in a state where the second bending upward and downward fixing lever is at a position other than a release position.

Disclosed embodiments include apparatuses for holding an endoscope handle and locking out an angulation lever of an endoscope handle. Given by way of illustration only and not of limitation, in an embodiment an illustrative apparatus includes: a frame; a support mechanism attached to the frame and configured to hold thereon an endoscope handle having an angulation lever; an attachment device configured to hold an endoscope handle in place on the support mechanism; and an angulation lever engagement mechanism configured to prevent an angulation lever of an endoscope handle from returning to a neutral position.

The present invention relates to a fluid supply device for an endoscope, including: a liquid supply unit for supplying liquids to the endoscope; a gas supply unit for supplying gases to the endoscope; and a control unit for controlling operations of the liquid supply unit and the gas supply unit, wherein the control unit includes: a foot switch located on the floor of an operating room to receive control commands on the operations of the liquid supply unit and the gas supply unit from a surgeon who uses the endoscope; and a controller for selectively operating the liquid supply unit and the gas supply unit according to the control commands received.

There are provided an endoscopic image processing device, an endoscopic image processing method, an endoscopic image processing program, and an endoscope system that appropriately notify region-of-interest information about a region of interest included in an endoscopic image according to an endoscope operator's action. An endoscope operator's action on a portion to be observed of an endoscopic image is recognized from endoscopic images, and first emphasis display where region-of-interest information is displayed in the endoscopic image at a first emphasis level and second emphasis display where the region-of-interest information is displayed at a second emphasis level relatively lower than the first emphasis level are switched according to a recognition result.

A mounting member includes: a body portion provided in a camera head including an image sensor, the body portion being rotatable about a first axis that passes through the body portion and connectable with an endoscope; a locking protrusion provided in the body portion and configured to lock with the endoscope; a detachable button configured to be movable with respect to the body portion and control attachment and detachment of the endoscope to and from the body portion; and a spring whose load applied to the locking protrusion changes according to an advancing/retreating operation of the detachable button with respect to the body portion. The detachable button includes a sliding portion extending in an advancing/retreating direction with respect to the body portion and configured to slide with respect to the body portion. The body portion includes a guide portion configured to guide a moving direction of the sliding portion.

The endoscopic device includes a main member having a front slot and a shaft member having a spiral strip selectively running through the slot. The spiral strip is connected to a rotational element whose front end is provided with an optical element. A camera support element is extended from the main member and a camera element is supported by the camera support element. By running the spiral strip through the slot to turn the rotational element and the optical element, a viewing direction of the camera element is altered by the optical element.

A medical observation system includes a multi-link structure in which a plurality of links is mutually coupled by joint parts, a medical observation apparatus attached on the multi-link structure, a control part configured to control the multi-link structure or the medical observation apparatus, and a user interface part by which a user inputs an instruction to change a visual field of the medical observation apparatus. When a user instructs to move a visual field of the medical observation apparatus vertically or horizontally, to rotate an oblique-viewing endoscope, or to change a magnification of the visual field via the user interface part, the control part controls the multi-link structure or the medical observation apparatus.
