This application is directed to the field of surgical gear. In particular, the application is directed to surgical loupes and eyewear used in the field of surgery.
Surgeons, dentists and hygienists use surgical loupes to magnify the area where they perform theft work. Traditional surgical loupes use a telecentric design where the user has to tilt their head downward so as to view the working area below them. The tilting of their head can lead to neck and back pain. For people in these professions, according to the American Dental Association, roughly 29% of disabilities are related to musculoskeletal disorders. These disabilities can lead to early retirement and loss of income.
Briefly described, aspects of the present disclosure relate to surgical loupes and eyewear.
An aspect of the present disclosure is surgical loupes. The surgical loupes have a housing portion, wherein the housing portion comprises a bridge, wherein a first lens housing is located at a distal end of the bridge and a second lens housing is located at an opposite distal end of the bridge, wherein the housing portion further comprises an attachment member adapted to be secured to eyewear; wherein each of the first lens housing and the second lens housing have located therein a mirror coated Littrow prism, wherein the mirror coated Littrow prism reflects light from the mirror coated portion of the Littrow portion through the hypotenuse portion the Littrow prism to eyes of a user; and wherein each of the first lens housing and the second lens housing have located therein at least one plano convex lens.
Another aspect of the present disclosure is a system. The system has an eyewear portion, surgical loupes operably connected to the eyewear portion, wherein the surgical loupes comprise; a housing portion, wherein the housing portion comprises a bridge, wherein a first lens housing is located at a distal end of the bridge and a second lens housing is located at an opposite distal end of the bridge, wherein the housing portion further comprises an attachment member adapted to be secured to eyewear; wherein each of the first lens housing and the second lens housing have located therein a mirror coated Littrow prism, wherein the mirror coated Littrow prism reflects light from the mirror coated portion of the Littrow portion through the hypotenuse portion the Littrow prism to eyes of a user; and wherein each of the first lens housing and the second lens housing have located therein at least one double concave lens or triplet lens.
To facilitate an understanding of embodiments, principles, and features of the present disclosure, they are disclosed hereinafter with reference to implementation in illustrative embodiments. Embodiments of the present disclosure, however, are not limited to use in the described systems or methods and may be utilized in other systems and methods as will be understood by those skilled in the art familiar with this disclosure.
Aspects of the present invention apply principles related to surgical loupes disclosed in Applicant's U.S. Pat. No. 10,247,965, incorporated herein by reference. The surgical loupe design utilizes a lens arrangement and an aluminum mirror coated Littrow prism to redirect a user's view and magnify the area where the user is working. This is accomplished while still allowing the user to maintain a straight neck and head posture.

A doublet lens is a type of lens made up of two simple lenses paired together. Such an arrangement allows for more optical surfaces, thicknesses, and formulations, especially as the space between lenses may be considered an “element” with respect to the lens design. A triplet lens is a compound lens consisting of three single lenses. A triplet lens provides a number of degrees of freedom to allow the lens design to overcome potential Seidel aberrations. Overcoming potential aberrations sharpens the image along with displaying a larger viewing area.

The mirror coated Littrow prism 510 is positioned proximate to a user's eye, with its slanted surface (the hypotenuse of the triangle formed by the cross-section of the prism) positioned proximate to viewing lens 121 through which the user looks. In an embodiment, an additional doublet lens is placed between the Littrow prism 510 and the viewing lens 121. In an embodiment, a triplet lens is placed between the Littrow prism 510 and the viewing lens 121. In an embodiment, both doublet and triplet lenses are used in various combinations between the Littrow prism 510 and the viewing lens 121. The lenses used depend on the desired magnification. In an embodiment, the lenses are positioned downward at an angle above one another. In an embodiment, the lenses are positioned centric to another with a tilt of approximately 60 degrees due to the ray deviation of the prism. In an embodiment, the lenses are grouped in three sections, which permits the user to rotate and shift the group of lenses inward or outward. The center lens or group of lenses can move as the left lens housing 112 or the right lens housing 114 is rotated. Groups of lenses permit reduction of aberrations and display a sharper image. Moving the respective location of the lenses permit the lenses to zoom in and out of the working area.

Bone conduction audio allows users implementing the surgical loupes to transmit music and other sounds to the user's inner ear through vibration of the cochlea, without involving the eardrum. This allows the user of the surgical loupes implementing the vibration mechanism to be able to interact and be aware with theft surroundings, yet be able to listen to podcasts/music/audiobooks while doing surgery.

In an embodiment, lenses may be inserted within the arrangement of the lenses for the surgical loupes that block blue spectrum light. Blue spectrum light blocking lenses are inserted into the surgical loupes to reduce harmful blue lights. Constant viewing of blue light from digital devices, sunlight, mobile devices, computer monitors, and LED illumination light at the surgery site can cause eye stains/damage and disrupt sleep patterns and the circadian cycle. In dentistry blocking blue spectrum light further prevents viewing curing lights that are within blue light emitting devices used to activate and cure composite filling materials and cement. Looking at them with regular clear glasses can damage a user's eyes.
In an embodiment, the anti-blue spectrum light protection is coated along with UV protection, to protect against light in the ultraviolet and blue-violet spectrum can damage the human eye, as well as leading to painful inflammation of the conjunctiva and cornea. The coatings can be applied on the loupes lenses so that the user doesn't magnify the entrance of the blue light. Similar to holding a magnifying glass and converging the rays into a point, which can generate a lot of heat.

Mounting portion 1116 permits the camera 1114 to be secured to a portion of the surgical loupes. Adjustment screw 1117 permits the lens portion 1118 to be adjusted via adjustment screw 1117. By twisting the adjustment dial 1119 the lens portion 1118 moves with respect to the adjustment screw 1117. The lens portion 1118 is able to be moved back and forth with respect to the area that is being recorded thereby adjusting the depth and focus of the camera 1114. Additionally, the lens portion 1118 is able to be removed and lenses with different zoom capabilities are able to be obtained. For example a 2× or 3× lens may be used. In some embodiments, lenses within the range of 1.5× to 10× are able to be used with the camera 1114. The camera 1114 is adapted to be used with any of the surgical loupes discussed above.
