An article of personal protective equipment (PPE) for covering a wearer's face when wearing loupes and/or a light mounted to an eyeglass frame, the apparatus including a set of adapters, each adapter mounted or configured for mounting to an eyeglass frame, wherein each adapter has an outward extending protrusion; and a transparent face shield with opposing sidewalls joined by a convex front with upper and lower portions angled inward to cover the wearer's face when wearing the loupes and/or light, each sidewall configured to engage one of the protrusions to align an apex of the convex with the loupes and/or light.

A head-mounted extended reality (XR) display device includes a rigid mounting element coupled to a frame. The XR display device further includes right-side and left-side visible light cameras coupled to the rigid mounting element, right-side and left-side near-infrared (NIR) cameras coupled to the rigid mounting element, and an NIR light-emitting diode (LED) configured to illuminate a region within a field of view of the NIR cameras. The visible light cameras are configured to capture stereoscopic visible light images within a field of view of the user when the user is wearing the frame, and the NIR cameras are configured to capture stereoscopic NIR images within the field of view of the user when the user is wearing the frame.

An endoscope and related method comprise a proximal handle and a distal shaft having an insertion end. A housing comprising a camera assembly may be mounted on an insertion end of the shaft and include at least one lens and an image sensor. The camera assembly housing is rotatable about an axis perpendicular to the long axis of the shaft, giving the camera assembly a variable field of view. The rotatable camera assembly housing may be mounted to the insertion end of the shaft so that the rotatable housing of the camera assembly comprises the distal-most element of the endoscope shaft or insertion end. The endoscope may include a circuit board having a first portion disposed within the proximal handle and one or more extension portions that extend within the shaft to the camera assembly and/or to a light source near the distal end of the shaft. At least one light emitter may be mounted on the insertion end of the shaft and configured to project light in a direction either toward or away from the field of view of the camera assembly. The light emitter may also be mounted on the camera assembly housing to direct light toward the field of view of the camera assembly. Power and communication lines can be co-located within a lumen of the shaft of the endoscope used for fluid irrigation or suction.

Disclosed is a method and system to construct a head strap for a dental or medical pair of magnifying loupe glasses. Key features of the disclosure are that the head strap is hygienic and very easy to disinfect, while at the same time being easy and quick to adjust and securely attach to the head, and quickly and securely attach to the temples of a standard loupe.

A head strap (120) for medical loupe glasses is provided, comprising two tubes (130, 132) of flexible wipe-clean material and a magnet (134, 136) located on each tube, the magnets (134, 136) being connectable by magnetic forces to effect securement.

This application concerns a loupe-based wearable device that is enhanced by a mounted visualization aid on the housing body of at least one of the loupe eyepieces, the aid providing a dual light source, a beam splitter, and a camera directed in the same optical path as a user's eyesight such that both visible light and fluorescent dye exciting light can be directed at a site of operation to enhance real time visualization of tissue resection.

Aspects of the disclosure are presented for a multifunctional platform that is configured for surgical navigation and is portable for use in different locations. The system includes a hardware component and a software component. The hardware component may include a portable or wearable device that can obtain multiple types of input data that can be used in remote visualization of a surgical setting. The hardware may include a headset with various types of cameras, such as a position camera and a visual camera for capturing 2D and 3D data, and circuitry for fusing or overlaying the 2D and 3D images together. In other cases, the hardware may include a bar attachment to a mobile device, such as a smart pad, with multiple camera sensors built in. In some embodiments, the hardware also includes a portable navigation system that can fulfill the functions of both surgical navigation and a surgical microscope.

Dental loupes feature a light source, a composite lens, and a blacklight lens. Each lens may be hingedly coupled to the light source to prevent composite from curing or cause composite to fluoresce. The dental loupes have magnets for securing the position of each lens and/or may have a formfactor configured to allow ease of rotation and positioning. In some examples, the dental loupes include a first bracket coupled to and rotatable about a second bracket via a pin. The first bracket has a first aperture configured to hold a light source. The second bracket has a second aperture configured to hold a composite lens and a third aperture configured to hold a blacklight lens. In a first configuration, the light source aligns with the composite lens, preventing curing of composite. In a second configuration, the light source aligns with the blacklight lens, causing composite to fluoresce.

A neckband-type medical headlight system includes a lighting unit and a magnifying glass provided in glasses or a headset, a control unit configured to control the lighting unit, and a battery and a power cable configured to supply electric power to the lighting unit. The control unit for controlling the lighting unit is composed of a neckband type to be seated around a user's neck. A pedal-type wireless control unit is further provided to enable a user to turn on and off the lighting unit using a foot.
