An endoscope includes a distal end portion main body arranged at a distal end portion of an insertion portion, the distal end portion main body including a recess, the distal end portion main body including at least one screw hole in at least one of a periphery of the recess or an interior of the recess, a lid configured to cover an opening of the recess, the lid including at least one through-hole at a position corresponding to the screw hole, a resin configured to fill a gap between the lid and the distal end portion main body, at least one screw configured to fix the lid to the distal end portion main body, the screw being inserted through the through-hole and screwed into the screw hole, at least one screw cover having an insulation property and configured to cover an upper surface of the screw, the screw cover being disposed closer to a proximal end side than to the recess, and a distal end cover configured to cover a part of the distal end portion main body.

An electronic module includes a three-dimensional wiring board including a cavity portion in which a bottom surface and four wall surfaces are formed, a plurality of electrodes being provided on the bottom surface, and a plurality of electronic components mounted on the plurality of electrodes and including a plurality of chip components and an image pickup module configured to pick up an image in an opening section direction of the cavity portion. A wall surface among the four wall surfaces that corresponds to a direction in which the plurality of chip components are arrayed is an inclined surface having an inclination with respect to the bottom surface.

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).

An elongated access device used in a medical system. The elongated access device slidably receives a medical tool and an ultrasound probe. The elongated access device includes a sheath and an intraluminal tip attached to the distal end of the sheath. The intraluminal tip includes ramp and nose donuts being spaced apart from one another and configured to be attached to one or more elongated sleeves. One or more orientation pins are engaged with the respective ramp and nose donuts and may be anchored within the sheath. The medical tool is engaged with a ramp formed in the ramp donut or a ramp received within the ramp donut. The ultrasound probe is configured to engage with the intraluminal tip so as to ensure that the medical tool directionality is oriented toward a target during a procedure.

An endoscope includes an insertion section, a channel, a raising base and a sterilizing device. The insertion section includes a distal end portion, and the distal end portion includes a recess. The channel is disposed in the insertion section, the channel communicating with the recess and the channel configured to receive a treatment instrument. The raising base is disposed in the recess, the raising base configured to guide the treatment instrument to protrude from the recess. The sterilizing device is disposed in the distal end portion, the sterilizing device configured to sterilize one or more of the channel and the recess and the raising base.

A coupler device for an endoscope that includes a main body having a proximal end configured to attach to the distal end portion of the endoscope, and a protective cover to reduce the ingress of debris, fluid, bacteria, or other unwanted matter from the working end of the endoscope which could lead to infection and decreased performance of the scope. The coupler device further includes a visualization section on the main body between the camera lens and light source of the endoscope and the target site within the patient. The visualization section includes one or more optical components configured to reduce an amount of reflected light from the surface and/or to inhibit condensation of water droplets on the surface. Reducing the glare and/or fogging of the visualization section significantly improves the surgeon's view of the target site through the optical coupler.

Apparatuses (e.g., devices, systems, etc.) and methods that may provide access to one or more tools to a remote site in the body including expandable and external working channels that may be part of a tube that is coupled to an outer surface of an elongate medical device, such as an endoscope.

Devices and methods for treating rhinitis are provided. An integrated therapy and imaging device is provided for single handheld use. The device may have a hollow elongated cannula, a therapeutic element coupled to a distal portion of the cannula, an imaging assembly coupled to the cannula to provide visualization of the therapeutic element, and an articulating region operably coupled to the imaging assembly to articulate the imaging assembly. The imaging assembly may be articulated so as to translate vertically, laterally, axially, and/or rotationally.
