A laryngoscope blade which improves the transmission of light from the laryngoscope to enhance the amount of light reflected from an area of interest in a patient. The laryngoscope blade has a channel which extends at least partially though the blade and receives a light source. The channel has a substantially transparent end face which is situated towards the blade end and has an optical clement adapted to reduce the ambient light signal from the light source in the channel.

Provided is an endoscope that can easily perform the attachment and detachment work of a proximal end side of a wire without impairing the operability of an operating part. The an endoscope includes an operating part (22) including an erection operating lever (20), an insertion part (24), an elevator (30), a wire (60) that is disposed to be inserted into a wire channel (62) to be movable forward and backward therethrough and is attachably and detachably coupled to the elevator (30) on a distal end side thereof, an opening part (94) that is provided at a proximal end of the wire channel (62) and delivers the proximal end side of the wire (60) to the outside of the operating part (22), a rotating member (96) that is disposed to be exposed to the outside of the operating part (22) and is configured to be rotatable around a rotational axis (96A) having a component in a direction orthogonal to a longitudinal direction of the operating part (22) depending on the operation of the erection operating lever (20), an engaged part (144) that is provided in the rotating member (96), and an engaging part (98) that is provided on the proximal end side of the wire (60) and is engageably and disengageably engageable with the engaged part (144).

A dilator releasably connected with an endoscope to dilate a stricture as the dilator that is releasably connected to a portion of a cylindrical body of the endoscope passes through the stricture. The endoscopic dilator is moveable between an open position and a closed position configured to enable the dilator to be secured to the endoscope. When the dilator is in the closed position, an inner surface or a component on the inner surface of the dilator frictionally secures dilator to the portion of the cylindrical body of the endoscope. When in the open position, the dilator is not frictionally secured to the portion of the cylindrical body of the endoscope.

A clipping system includes a cap configured to be mounted over a distal end of an endoscope. A clip mountable over the cap to move between an insertion configuration, in which first and second jaws extend over opposing portions of the cap so that the first and second jaws are separated from one another, a review configuration, in which the clip is moved distally relative to the cap so that a portion of the clip extends distally until at least a portion of the clip extends into a field of view of the optical system of an endoscope on which the cap is mounted, and a deployed configuration in which the clip is moved distally off of the clip so that the first and second jaws are drawn toward one another under the bias of the at least one hinge to close over tissue received therebetween.

An endoscope includes a detachable wireless imaging device and an insertion tube having a distal end region. The attachment of the detachable wireless imaging device detachably attaches the detachable wireless imaging device to the distal end region of the insertion tube.

Provided are ultrasonic endoscope and a balloon with improved balloon detachment resistance.

An ultrasonic endoscope includes an ultrasound oscillator unit disposed in a distal end part of an insertion part, and a balloon attachably and detachably attached to the distal end part to cover an outside surface of the ultrasound oscillator unit, the distal end part is provided on at least one of a distal end side or a proximal end side of the ultrasound oscillator unit and has balloon attachment grooves formed in an outer peripheral surface of the distal end part along a peripheral direction, the balloon has a balloon body provided with openings, and a first annular locking part and a second annular locking part that are provided in the opening of the balloon body and are locked in the balloon attachment grooves, and the first annular locking part and the second annular locking part have a detachment prevention shape for restraining detachment from the balloon attachment grooves.

A medical device comprising a handle, a shaft extending from the handle, and an inflatable module at a distal portion of the shaft, the module including a camera, wherein the shaft includes a body defining a first channel extending between a first end configured to be in fluid communication with a fluid source, and a second end in fluid communication with the module, and wherein inflation of the module alters a viewing angle of the camera relative to an axis of the distal portion of the shaft.

An endoscope add-on assembly adapted to be attached to a target endoscope. The assembly includes an ultrasound imaging sub-assembly, including a communications cable connected to an ultrasound imaging head and an imaging head movement sub-assembly, including a conduit, holding a tension member that is attached to the ultrasound imaging head. Further included are connective elements, adapted to permit the endoscope add-on assembly to be attached to the target endoscope. Finally, the imaging head movement sub-assembly is detachable from the ultrasound imaging sub-assembly, thereby permitting the imaging head movement subassembly to be processed separately from the ultrasound imaging sub-assembly, after use.

A view optimizing assembly, method and kit for use in combination with a laparoscope having a lens located on the shaft tip of the laparoscope, and a source of insufflation CO.sub.2. The invention includes a multi-lumen sheath assembly, a deflector assembly in fluid communication with the lumens of the sheath assembly, wherein the flow of CO.sub.2 through the lumens forms a vortex when coming into contact with the deflector assembly, thereby preventing fogging of the laparoscope lens.

An ear examination tool comprises a handle and a speculum mount coupled to the handle. The speculum mount is configured for retaining a disposable speculum. An spacing element is coupled to the handle and extends from the handle. A smartphone mount is coupled to the spacing element, and the spacing element is configured to maintain an optical separation distance between the speculum mount and the smartphone mount. The tool enables a clear view of the ear canal while allowing access by, and manipulation of, a microsuction tool being inserted into the ear canal. The extensive optical and data processing functionality of a “smartphone” can be integrated at low cost into an ear examination tool to provide a substantially improved piece of equipment for assisting in ear examination and microsuction of the ear.
