An endoscope system for use with a light guide having an endoscope; and a reflector configured for placement between the endoscope and the light guide. The reflector has a translucent portion for transmitting light from the light guide and a reflective portion for reflecting light from the light guide back into the light guide.

A light therapy diagnostic device comprising a shaft, an optical waveguide disposed in a lumen of the shaft and being movable forward and backward in a longitudinal direction of the shaft, and a transparent member disposed in the lumen and located distal to the optical waveguide, wherein: the optical waveguide guides a first light and a second light; the shaft has a lateral emission window which allows the first light and the second light to be emitted toward a lateral direction and a distal emission window which allows the first light to be emitted toward a distal direction; the optical waveguide includes a core and a clad, wherein a distal end surface of the core is inclined with respect to an optical axis of the optical waveguide; the first light passes through the transparent member in a state where the optical waveguide is in contact with the transparent member.

Provided is an endoscope system that inexpensively guides an extra-fine endoscope using an overtube. An endoscope system includes an endoscope and an overtube. The overtube includes an endoscope channel that allows passage of the endoscope, being bendable according to an operation. The endoscope includes a light irradiation unit and an imaging unit.

An endoscope apparatus includes a processor. An image signal includes a first image signal corresponding to first light and a second image signal corresponding to second light. The processor determines at least one of whether or not a submucosa region or a bleeding region is included in an image based on the image signal. In a case where the submucosa region is included, the processor performs conversion processing that increases a combination ratio of the second image signal to the first image signal in an image region including the submucosa region, and allocates a combined image signal to a G-channel. In a case where the bleeding region is included, the processor performs conversion processing that increases a combination ratio of the first image signal to the second image signal in an image region including the bleeding region, and allocates the combined image signal to the G-channel.

A needle camera adaptor includes a tube-shaped body having a proximal end, a distal end, a longitudinal axis, and a lumen that extends along the longitudinal axis. A centrally-located lateral access opening is formed in an outer wall of the tube-shaped body. A needle securing channel is formed in the outer wall and extends between the lateral access opening and the distal end of the tube-shaped body. A curved suture needle is disposed within the needle securing channel. The needle securing channel and the curved suture needle extend along an axis that defines an oblique angle with the longitudinal axis of the needle camera adaptor. A visualization device, facing distally, is positioned within the lumen at the proximal end of the tube-shaped body. The lateral access opening, the needle securing channel, and the curved suture needle are located within a field of view of the visualization device.

A speculum having an elongated portion with two hinged jaws. In a first mode, the jaws are positioned adjacent each other and in a second mode, the jaws are spaced apart. The speculum is designed such that another identical speculum can be stacked on the original speculum.

A laryngoscope that includes a low-profile, straight laryngoscope blade that is thin and tapered in width and height, and designed to be intuitive in use and function. A distal tip of the blade may be configured to be placed in the anterior oropharynx with the angled camera (e.g., 10 degrees-40 degrees), thereby providing views of the airway and facilitating blade advancement. Real-time image data collected during a laryngoscopy may be communicated to a medical professional for immediate and ongoing feedback during a laryngoscopy or communicated to an electronic medical record. The laryngoscope provides first responders and airway managers of varying abilities a unique, portable, wireless laryngoscope to optimally manage airways and provide the greatest likelihood of safe, atraumatic airway access. The laryngoscope with the transformational laryngoscope blade design having an angled camera and wireless video forms a singular, effective instrument for airway managers and medical professionals.

A light source apparatus includes: a first light source; a second light source configured to emit light having a dimming resolution lower than a dimming resolution of the first light source; a holder configured to hold the first light source and the second light source on a first surface of the holder; a substrate provided to face a second surface of the holder, the second surface being different from the first surface, and a circuit configured to control driving of the first light source and the second light source being mounted on the substrate; a first wiring configured to electrically connect the first light source and the substrate; and a second wiring configured to electrically connect the second light source and the substrate, wherein a length of the first wiring is shorter than a length of the second wiring.

A computer program or the like having high ability of detecting a lesion is provided. A computer program causes a computer to execute processing of: acquiring an image captured by an endoscope; inputting the image captured by the endoscope to a first recognizer that recognizes a lesion section on the basis of the image and a second recognizer that recognizes the lesion section with higher recognition accuracy than the first recognizer on the basis of the image; acquiring provisional information including a recognition result recognized by the first recognizer; outputting an image including the acquired provisional information; acquiring confirmation information for the provisional information including a recognition result recognized by the second recognizer; and outputting an image including the acquired confirmation information.

An imaging module includes an imaging element including a light receiving surface, an electrode surface on a side opposite to the light receiving surface, and imaging element electrodes formed on the electrode surface, a substrate including a first surface, a second surface on a side opposite to the first surface, and a first end surface facing the electrode surface, a cable portion having a conductor electrically connected to the imaging element electrodes via a wire on the substrate, a sealing resin that covers at least the first surface and the second surface, and an identification resin attached to a portion of the sealing resin on the first surface or a portion of the sealing resin on the second surface.
