Described herein is a video laryngoscope apparatus for inspection of an oral cavity region of a patient is disclosed. The video laryngoscope includes an apparatus body, a camera arm unit configured to receive and releasably attach thereto a disposable laryngoscope blade, a light source coupled to the camera arm unit, a communication unit, and a power source. The apparatus body includes a proximal end and a distal end, and the apparatus body is elongate and configured to be hand-held by an operator of the video laryngoscope. The camera arm unit includes a proximal end and a distal end with a camera, and the proximal end of the camera arm unit is connected to the distal end of the apparatus body utilizing an adjustable rotary position linkage member. The communication unit is connected via a linkage device to the proximal end of the apparatus body, and the power source is housed by the apparatus body.

An optical device includes an optical window, a gas/liquid supply nozzle that includes an opening from which gas and liquid are jetted and selectively jets the gas and the liquid to wash an effective region of the optical window, a disposition surface on which the optical window and the nozzle are disposed, and a first hydrophobic portion that has a hydrophobic surface property and is formed in a part of a region of the disposition surface present between the effective region and the nozzle and between two tangent lines intersecting with a jet direction of the nozzle and extending to be tangent to the effective region from both ends of the opening in a width direction along the disposition surface.

A tip section of a multi-camera endoscope includes a front-pointing camera on a planar surface of a distal end of the tip section and two side-pointing cameras positioned on a cylindrical surface in proximity to the planar surface such that the side field of view provided by the two side-pointing cameras partially overlaps with the front field of view provided by the front-pointing camera. The tip section further includes a working channel configured for insertion of a surgical tool; and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.

The present invention provides an improved visual laryngeal mask comprising a snorkel, an end of the snorkel is provided with a fixing seat. The fixing seat is provided with an airbag, and the fixing seat has a recess which is provided with an airway opening. The inner wall of the snorkel longitudinally extends an imaging cavity and a cleaning channel. The imaging cavity has a built-in imaging device, and the imaging cavity and the cleaning channel protrude forward relative to the airway opening to form a stopper which prevents an epiglottis from blocking the imaging device.

Connectors for connecting or linking one instrument or object to one or more other instruments or objects are disclosed herein. In some embodiments, a connector can include a first arm with a first attachment feature for attaching to a first object, such as a surgical access device, and a second arm with a second attachment feature for attaching to a second object, such as a support. The connector can have an unlocked state, in which the position and orientation of the access device can be adjusted relative to the support, and a locked state in which movement of the access device relative to the support is prevented or limited. Locking the connector can also be effective to clamp or otherwise attach the connector to the access device and the support, or said attachment can be independent of the locking of the connector.

An endoscope is provided to examine internal organs with front and rear views. The endoscope comprises a shaft extending from a distal end in a rearward direction along a longitudinal axis towards a proximal end, with the distal and proximal ends defining a hollow channel extended there-through. The endoscope further comprises a first lens positioned adjacent to the distal end and configured to receive a first image in a forward direction along the longitudinal axis, with the forward direction generally 180 degree from the rearward direction. The endoscope further comprises a rearview module positioned adjacent to the distal end. The rearview module comprises a second lens configured to be positioned adjacent to the distal end, and receive a second image in a target direction having a directional component in the rearward direction along the longitudinal axis, independently of the first lens receiving the first image in the forward direction.

An endoscope apparatus includes a processor. The processor conducts analysis whether an endoscope image has been appropriately captured or not on the basis of the endoscope image. The processor acquires correction restriction information that is at least one of a restriction regarding a size of a lumen of an image-captured portion or a restriction regarding a submucosa state of the image-captured portion. The processor generates correction information regarding correction of image-capturing conditions for allowing the endoscope image to be appropriately captured under a restriction of the correction restriction information in a case where it is analyzed that the endoscope image has not been appropriately captured, and outputs the correction information on a monitor.

A trocar including a trocar head attached to a cannula having a lumen with a distal opening, the cannula includes at least one elastomeric band positioned across said lumen.

An endoscope includes a distal end surface provided at a distal end of an insertion part; an observation window provided on the distal end surface; a nozzle; and a first protective projection, a second protective projection, and a third protective projection disposed at an outer peripheral part of the distal end surface and provided to project forward of the observation window. In all combinations of imaginary planes capable of coming into contact with the first protective projection, the second protective projection, and the third protective projection from a front side, the imaginary planes are disposed forward of the observation window, the imaginary planes are disposed at the same height as or forward of the nozzle, and the observation window and a portion of the nozzle are included within an outer ring region surrounded by the first protective projection, the second protective projection, and the third protective projection.
