A balloon is attachably and detachably mounted on an insertion part of an endoscope. A distal end part provided at a distal end of the insertion part includes an image pickup optical system, an illumination optical system, and a beam light-emitting unit. A subject is irradiated with measurement light by the beam light-emitting unit. It is possible to recognize the position of a spot from a subject image, and to measure an observation distance to an object to be observed, the size of the object to be observed, and the like.

An endoscope includes an image-capturing module. The image-capturing module includes a lens barrel housing an optical system, an image sensor, a sensor holding member that relatively fixes the lens barrel and the image sensor, and a flexible substrate through which a signal of the image sensor is transmitted to a transmission cable. The flexible substrate is bendable at an arbitrary number of bending portion.

A compound-eye endoscope includes two or more image-capturing modules, a sub-frame, and an outer shell. The two or more image-capturing modules are formed in the same outer shape, and each of the image-capturing modules includes a lens barrel housing an optical system, an image sensor, and a sensor holding member that relatively fixes the lens barrel and the image sensor. The sub-frame relatively fixes each of the two or more image-capturing modules. The outer shell accommodates and fixes the sub-frame and the two or more image-capturing modules.

A cable connection structure is provided with an electronic component including electrodes on an electrode-forming surface, a cable including electric wires connected to the electrodes respectively, and a buried member which is composed of a cured resin and embedded with the electric wires. At least three electric wires are separating wires including separating regions being separated from each other in the normal direction as being distant from the electrode-forming surface. At least three electrodes are arranged side by side on a virtual circle. At least three separating wires are connected to the at least three electrodes. The separating regions of the at least three separating wires are provided to be located eccentric radially outwardly in the virtual circle as being distant from the electrode surface in the normal direction of the electrode-forming surface. An angle between the separating region and the normal direction of the electrode-forming surface is 10 degrees or more and 45 degrees or less.

Provided herein is a tip component of a multi camera endoscope, the tip component accommodates a plurality of cameras configured to jointly provide a field-of-view (FOV) of at least about 270 degrees and a plurality of front illumination modules; wherein the tip component includes a plurality of window elements of sapphire glass soldered using a noble-metal, within respective openings on the housing thereof, wherein each of the cameras and illumination modules is positioned behind a respective window element. Further provided are methods of manufacturing the tip component and methods of using the same.

A true-seeing infrared industrial endoscope endoscope includes an external shell protective unit including a housing and an electrical appliance component box connected to a rear end of the housing. A cavity of the housing is provided with a dual capturing-imaging unit including at least two capturing-imaging subunits. Each of the capturing-imaging subunits includes a light splitter, an image capturing lens, an infrared imaging tube, and a visible light imaging tube. The electrical appliance component box is provided with a communication module and a power supply electrically connected to the dual capturing-imaging unit and the communication module. The communication module is communicatively connected to the dual capturing-imaging unit and an upper computer via a communication bus, and the power supply is electrically connected to the dual capturing-imaging unit via a power bus.

An imaging condition set in a first region of a three-dimensional model of a subject and an imaging condition set in a second region of the three-dimensional model are different from each other. A processor of an observation device determines whether or not the imaging condition that has been set in the first region or the second region including a position on the three-dimensional model is satisfied. The position is identified on the basis of a position of an imaging device and a posture of the imaging device. The processor displays observation information on a display on the basis of a result of determination. The observation information represents whether or not the first region or the second region including the position on the three-dimensional model has been observed.

The present disclosure involves object recognition as a method of registration, using a stereoscopic camera on Augmented Reality (AR) glasses or an endoscope as the image capture technology. Exemplary objects include surgical tools, anatomical components or features, such as bone or cartilage, etc. By detecting just a portion of the object in the image data of the surgical scene, the present disclosure may register and track a portion of the patient's anatomy, such as the pelvis, the knee, etc. The present disclosure also optionally displays information on the AR glasses themselves, such as the entire pelvis, the femur, the tibia, etc. The present disclosure may include combinations of the foregoing features, and may eliminate the need for electromagnetic, inertial, or infrared stereoscopic tracking as the tracking technology.

A camera head includes an airtight case which includes an image pickup unit having an image pickup device and the like as a heat source in an inner portion and includes a partition wall to secure air-tightness with respect to an outside of the airtight case, a heat transfer sheet which connects the heat source and an inner surface of the partition wall to transfer heat generated at the heat source to the partition wall, a heat sink arranged on an outer side of the partition wall of the airtight case, and a spring member which is interposed between an outer surface corresponding to the inner surface of the partition wall of the airtight case connected to the heat transfer sheet and the heat sink to transfer heat from the outer surface of the partition wall to the heat sink.

Dental periscopes having mounting clips configured to couple to mobile devices are disclosed. A patient can mount the dental periscope to a mobile device by coupling the mounting clip of the periscope to the mobile device. The patient can then use the mobile device-mounted dental periscope to capture image and/or video data of one or more dental structures. The captured image/video data can be sent to a remote system to obtain a remote dental diagnosis based on the captured data. The remote diagnosis may be an automated diagnosis generated by a trained machine learning classifier.
