A surgical access assembly comprises a trocar and a surgical instrument. The trocar comprises a housing and an access tube extending distally from the housing. The housing comprises a hollow light emitter. The housing and the access tube define a lumen extending through the housing and the access tube. The hollow light emitter is configured to project light in the lumen. The surgical instrument comprises an end effector and a shaft extending proximally from the end effector. The shaft comprises an optical receiver positioned within reach of the light from the hollow light emitter. The shaft further comprises a light guide extending from the optical receiver along at least a portion of the shaft toward the end effector.

An endoscope insertion shape observation probe that is elongatedly formed along a longitudinal axis direction and is insertable into a channel provided in an endoscope insertion section or is incorporated in the endoscope insertion section includes an electronic component, a housing section having a recessed shape that houses the electronic component, a pair of electric connection sections provided in the housing section, a pair of electric connection terminal sections provided in the electronic component and engaged with and electrically connected to the electric connection sections, the electric connection terminal sections mechanically holding the electronic component in the housing section, a groove section formed in the housing section, and two attaching-direction defining terminal sections provided in the electronic component, the attaching-direction defining terminal sections engaging into the groove section and defining a direction around a longitudinal axis in which the electronic component is attached to the housing section.

An endoscope handpiece and system may include an angle of view selector, a depressible button, which may be connected to a lock disposed within a port of the endoscopic handpiece. The system may further provide an endoscope, which may be connected to the handpiece via the port and locked in place by the lock.

An insertion apparatus includes an insertion section, a rotational housing, a motor, and a controller. The motor rotates the rotational housing. The controller designates a rotational direction of the motor. The controller limits the rotational direction of the motor to allow the insertion section to move only in a removal direction when inspection control for inspecting an operation relative to an insertion direction of the insertion section is initiated.

An endoscope system includes an image pickup device that picks up an image of an inside of a subject, and outputs two or more digital signals, an electro-optical conversion section that converts the two or more digital signals outputted from the image pickup device into optical signals, and outputs the optical signals, an optical transmitting section that includes two or more optical transmitting members, and is adapted to transmit, in parallel, by the two or more optical transmitting members, two or more optical signals outputted from the electro-optical conversion section, and an output selection section provided between the image pickup device and the electro-optical conversion section, and being capable of combining, and outputting to one optical transmitting member, the two or more digital signals that are supplied to the two or more optical transmitting members, based on a transmission state of data optically transmitted by the optical transmitting section.

Apparatuses and methods for medical applications and, more particularly, to steerable flexible medical devices applicable to guide tools and devices in medical procedures, including endoscopes, cameras, and catheters are provided. The apparatuses and methods also include generating a panoramic image of an interior of a branching structure at or near the distal end of the flexible medical device wherein the panoramic image is generated based on the images of the branching structure.

A system for preventing motion sickness resulting from virtual reality or augmented reality is disclosed herein. In one embodiment, the system includes a virtual reality or augmented reality headset configured to be worn by a user, the virtual reality or augmented reality headset configured to create an artificial environment and/or immersive environment for the user; at least one fluidic lens disposed between an eye of the user and a screen of the virtual reality or augmented reality headset; and a fluid control system operatively coupled to the at least one fluidic lens. In another embodiment, the system includes at least one tunable prism disposed between an eye of the user and a screen of the virtual reality or augmented reality headset, the at least one tunable prism configured to correct a convergence problem associated with the eye of the user.

An endoscope tip part including a tip housing at least partially enclosing an interior cavity and including a window, and a vision assembly accommodated in the interior cavity and including an imaging subassembly including an image sensor viewing in an optical direction through the window of the tip housing, a light source comprising an illumination surface for emitting light, a separate frame component including a light shielding wall made of an opaque material and extending between the image sensor and the light source so as to at least partially shield the image sensor from light emitted from the light source.

A multi-organ imaging system including a camera lens, a stationary, multi-examination illumination unit (SMEIU), and an attachment holder is provided. An industrial camera unit (ICU) for imaging multiple organs, for example, ear, nose, throat, and skin, is housed in a camera body. The camera lens has a fixed focal length and an iris for optimizing examination and imaging of the organs. The SMEIU is integrated to the camera body and includes illuminators arranged in a geometrical configuration. The attachment holder accommodates an organ examination attachment selected for examining an organ. The illuminators, in optical communication with one or more reflective surfaces in the organ examination attachment, produce shadowless illumination during examination and imaging of each organ, without requiring replacement of the SMEIU for examining each organ. A display unit, accommodated in a display holder detachably attached to the camera body, assists in aiming the camera lens and visualizing each organ.

A bending operation device includes a bending operation lever, a wire pulling member, bending operation wires, and tubular members. The bending operation lever is tiltably supported to have an angle with respect to a longitudinal direction of an operation unit of an endoscope. The wire pulling member includes arm portions displaced in conjunction with tilt motion of the bending operation lever. The bending operation wires are connected to the arm portions. The bending operation wires cause bending motion of a bendable part disposed in an insertion section of the endoscope. A respective one of bending operation wires is inserted in each of the tubular members. The tubular members (i) change extension directions of the plurality of bending operation wires and (ii) guide the plurality of bending operation wires to the plurality of arm portions.
