An endoscope device having one or more processors configured to perform a control process including: processing an imaging signal to generate image data of a display image of a subject, wherein the image signal is generated by an image sensor, wherein the image sensor is arranged at a distal end of an insertion portion, and wherein a bending actuator is configured to bend the distal end; setting a first measurement point and a second measurement point on the display image; calculating a first subject distance from the first measurement point to a reference point of the image sensor, and a second subject distance from the second measurement point to the reference point; calculating a difference value between the first subject distance and the second subject distance; and controlling the bending actuator to bend the distal end of the insertion portion such that the difference value is decreased.

An adapter for use with an endoscope. The adapter including: at least first and second axis-shifted lenses, each of the first and second axis-shifted lenses including a truncated portion, the first and second axis shifted lenses being arranged side by side so that respective first and second optical axes are parallel to each other; and a prism arranged further distally than the first and second axis-shifted lenses, the prism being configured to change a viewing direction of each of the first and second axis-shifted lenses; wherein at least a portion of each of the truncated portions of the first and second axis-shifted lenses is arranged further outward in the radial direction than the prism.

A device comprises a cannula having a first end, a second end, and a channel between the first end and the second end; an imaging probe couplable to the first end of the cannula, where the imaging probe includes: a transducer, and a reflective surface; and a biopsy device coupled to the cannula, where the biopsy device is configured to collect a tissue sample from an organ of a patient.

A beam combining device for combining light from a first light source and light from a second light source of a light-source device for a medical apparatus includes a body made of a transparent material, a face which reflects in at least either a dichroic or polarization-dependent manner and is situated in or on the body, which face is transparent to light having a first spectrum or a first polarization and reflects light having a second spectrum or a second polarization, and a light-entrance face on the body, which light-entrance face is provided and arranged so that light enters the beam combining device through the light-entrance face. At least either the light-entrance face or the face reflecting in a dichroic or polarization-dependent manner is curved.

An image capturing device comprises an elongated body, an imaging window coupled to a distal end of the elongated body, and a heat source within the elongated body. The heat source is configured to apply heat to the imaging window to remove condensation from or prevent condensation from forming on the imaging window.

Exemplary apparatus, systems, methods of making, and methods of using a configuration in an optical arrangement for spectrally encoded endoscopy (SEE) probe can be provided. For example, the probe can comprise a fixed guiding portion and a rotatable dispersive portion.

A light source apparatus includes an optical illumination unit that converts optical characteristics of primary light emitted from a light source unit and emits secondary light different from the primary light; and an adapter unit that outwardly emits illumination light generated based on the secondary light emitted from the optical illumination unit and that is attachable to/detachable from the optical illumination unit. A radiation angle control member converts a traveling direction of the secondary light so that the secondary light allowed to emit from a light conversion member toward the radiation angle control member in the secondary light allowed to emit from the light conversion member travels toward the adapter unit through the secondary light emit portion.

There is provided an endoscope imaging unit including parallel electric wires, an image sensor located on a front end side by being separated from front ends of the respective electric wires, and having a light incident surface substantially perpendicular to the electric wires, a flexible substrate located between the electric wires and the image sensor, having a circuit, and conductively connecting the respective electric wires to the circuit, an image sensor mounting peninsula portion bent with respect to the substrate, and mounting the image sensor thereon by conductively connecting the image sensor to the circuit, and a circuit mounting peninsula portion extending from the substrate, located by being bent to a side opposite to the image sensor before the image sensor mounting peninsula portion, and mounting and conductively connecting an electronic component or the circuit pattern to the circuit.

An endoscope having an elongate shaft and a system tube, which extends inside the shaft and in which an image carrier is arranged, the system tube is held in an axial direction of the shaft by means of at least one resilient latching element, and a method for producing such an endoscope and to a latching element for such an endoscope.

An endoscope capable of both improving accuracy of position control of a treatment tool and ensuring a gap for sucking a liquid is provided. The endoscope includes an insertion portion having a round tubular shape to be inserted into a body lumen, and includes: a treatment tool passage having one end opened on a distal tip surface of the insertion portion, penetrating the insertion portion in an axial length direction, and allowing a treatment tool to pass through; and a fluid passage having one end opened on the distal tip surface of the insertion portion, penetrating the insertion portion in the axial length direction, and allowing a fluid that has flowed from the one end to flow through, in which the treatment tool passage and the fluid passage are partially continuous in a cross-sectional view.
