{ THE SYSTEM COMPRISING A HEADLIGHT WITH 2 LIGHT SOURCES AND A BINOCULARS WITH RIGHT OBJECTIVE LENS AND LEFT OBJECTIVE LENS BEING NEARER}

The present invention relates to a combination of a headlight worn on a worker's head to illuminate the front and binoculars for magnifying a point illuminated by the headlight, and more specifically, the headlight includes an upper-line light source on the sagittal suture surface and It is divided into a sub-view light source, and the binoculars reflect the path of light using a prism or a flat mirror to see into the narrow hole with both eyes, thereby making the distance between the left and right objective lenses of the binoculars narrower than the distance between the left and right eyepieces. are binoculars

Otolaryngologists perform surgery on narrow and deep areas such as the ear and the inside of the nose. At this time, most of the operation is performed wearing a headlight. In the headlight, the light of the light source illuminates a narrow hole, and the light source is located not far from the center of the eyebrow so that the reflected light reaches the doctor's eye. However, if there is only one light source, the shadow by the surgical tool is thick, so it is better to spread the light source as wide as possible, but these two propositions are difficult to coexist with each other. In the end, the best position for the light source is at a point not far from the forehead that does not block the field of view. On the other hand, the human eye has two left and right, and the pupil distance is usually about 60mm~70mm. However, when surgery is required in a place such as the ear with a narrow entrance and deep depth, this pupil distance is too wide to see with both eyes, so it is difficult to see with both eyes. Either through a binocular microscope, or in general outpatient treatment, it is inevitably possible to see the operating unit with a single eye. Using a surgical microscope having a complex structure has many disadvantages, such as high cost and limited movement of the operator's head. Therefore, headlight binoculars with binoculars attached to the headlights are required. In this case, binoculars in which the distance between the left and right objective lenses is narrower than the distance between the left and right eyepieces is useful. That is, the best light source for the headlight avoids the position of the objective lens of the binoculars and is placed in two places just above the eyebrow and just below the eyebrow, and the distance between the left and right objective lenses is narrower than the distance between the left and right eyepieces. are binoculars

Binoculars are combined with two telescopes symmetrically with the sagittal plane of the wearer, and the eyepiece is configured to fit the left eye and the right eye. As the telescope, a Kepler type telescope and a Galilean type telescope are generally used. In this case, in order to make the distance between the left and right objective lenses of the binoculars narrower than the distance between the left and right eyepieces, it is possible by changing the direction of light using a total reflection prism or a flat mirror.

Such equipment is not only necessary for otolaryngologists. Its usefulness is the same in other fields where you have to work in narrow and deep places.

Although there have been products in which binoculars and headlights are combined in the prior art, the distance between the left and right objective lenses using a total reflection prism or a flat mirror is the distance between the left and right eyepieces, including two light sources: an upper-line light source and a lower-line light source. There is no headlight binocular system that incorporates narrower binoculars. In addition, conventional binoculars often use total reflection prisms [poroprisms] to change the direction of light. However, these prisms are heavy in weight and have disadvantages of lengthening the barrel due to refraction of light.

In order to solve this problem, the present invention proposes a system in which a headlight having two light sources, an upper-line light source and a lower-line light source, and binoculars in which the distance between the left and right objective lenses is narrower than the distance between the left and right eyepieces is combined. Also, we present a binocular using a plane mirror instead of a prism between the objective lens and the eyepiece of the binoculars.

This headlight binocular system enables binocular vision under optimal lighting when operating narrow and deep areas, is light in weight, and reduces manufacturing costs.

In the first or second embodiment of the present invention, the binoculars are Kepler type telescopes. The Kepler-type telescope is a telescope in which both the objective lens and the eyepiece are convex lenses, and an image composed of only the objective lens and the eyepiece is an inverted image. In order to establish such an inverted image, an erection system is usually disposed between the objective lens and the eyepiece, and there are various types of such an erection system. In the first embodiment of the present invention, this sizing system is composed of two poroprisms. Also, the second embodiment of the present invention is an example in which the two poroprisms are replaced with corresponding plane mirrors.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. 1 is a view from the side of a state in which the headlight binoculars of the first embodiment or the second embodiment proposed by the present invention are worn on the head, the headlight is the upper gaze light source 11 and the lower gaze light source 12 in the front ), and including a support 13 connecting the upper line of sight light source and the lower line of sight light source, the headband 14 in the form of a beam bent in a bow shape along the sagittal suture surface of the wearer from the upper end of the support. attached to the top of the support. Here, the light from the upper line-of-sight light source and the lower line-of-sight light source is installed at an angle to face one point in front. The binoculars 2 are positioned between the upper line of sight light source and the lower line of sight light source, are coupled with the support, and are installed at an angle so that the field of view of the binoculars is visible at the front one point. Figure 2 is a perspective view showing only the binoculars of the headlight binoculars of the first or second embodiment of the present invention. In the binoculars, two telescopes are symmetrically coupled to the frame 27, and the two telescopes are movable left and right according to the wearer's pupil distance. There is a hook 271 protruding from the front of the frame, and the hook is inserted into the support 13 of the headlight and coupled thereto. 3 shows the light source 11, the binoculars 2, and the operator's left and right eyes 31 of the headlight binoculars of the first or second embodiment of the present invention, and the light source and the objective lenses of the binoculars are all narrow. It is a partial view from above of the situation facing the deep hole bottom (0). 4 is a view showing the positional relationship of the upper light source 11, the lower light source 12, and the right objective lens 21 and the left objective lens 25 of the binoculars according to the first or second embodiment of the present invention. indicates the status. 5 is a cross-sectional view showing only optical parts of one telescope among the left and right telescopes constituting the binoculars of the first embodiment of the present invention. is composed of 6 is a cross-sectional view showing only optical components of one of the left and right telescopes constituting the binoculars of the second embodiment of the present invention. There are four planar mirrors 24 as an erecting system between the objective lens 21 and the eyepiece 22. If a flat mirror is used instead of a captive prism, weight can be reduced, and the length of the barrel can be shortened.

At this time, the poroprism or a plane mirror corresponding to the poroprism establishes the image and at the same time changes the direction of the light beam to separate the optical axis of the objective lens from the optical axis of the eyepiece, and as a result, the distance between the left and right objective lenses of the binoculars becomes the left and right eyepieces It also performs the function of making it closer than the distance between them.

Hereinafter, a first embodiment and a second embodiment of the present invention will be described in more detail with reference to FIG. 3 . Light from the light source 11 goes straight in the direction indicated by the dashed-dotted line to illuminate the hole, and the light reflected from the hole bottom 0 comes out in the solid line direction and enters the left and right objective lenses 21 and 28 of the binoculars. Light passing through the optical axis of the objective lens is changed in direction by the poroprism or planar mirror and passes through the optical axes of the left and right eyepieces 22 and 29 that are moved outward than the optical axes of the left and right objective lenses and enters the pupil of the wearer's eye 31 . If there is no such binoculars, or if you use binoculars composed of a general telescope in which the optical axis of the eyepiece and the optical axis of the objective lens are coincident, the gaze has no choice but to follow the dotted line from the pupil, so that the deep inside the hole (0) can be viewed with both eyes. can't

4 is a view showing the positional relationship between the light source of the headlight and the objective lens of the binoculars in the embodiments presented in the present invention, that is, the embodiment viewed from the front, that is, from the bottom of the hole (0). As described above, in this embodiment, there are objective lenses 21 and 28 of binoculars on the left and right, and the light sources 11 and 12 are arranged vertically. There is a dashed-dotted line connecting the centers of the left and right objective lenses and a dashed-dotted line connecting the centers of the upper and lower light sources. At this time, like the objective lens, if the distance between the upper and lower light sources is far from the forehead, light cannot enter the hole. That is, both the upper/lower light source and the left/right objective lens should be located close to the center of the eyebrow. In such a narrow area, the method that can avoid the interference of each part and reduce the shadow caused by the surgical tool the most is as shown in FIG. 4 that the distance from the eyebrow to the top and bottom of the eyebrow, the distance from the eyebrow to the objective lens of the binoculars, and the It is optimal to place the light sources at about the same point.

5 is a cross-sectional view showing only the optical component of one telescope according to the first embodiment of the present invention, and between the objective lens 21 and the eyepiece 22, two porographic prisms 23 are arranged in a right angle direction to establish an image. An example of the function of moving the optical axis of the eyepiece outward than the optical axis of the objective lens is shown. 6 is a cross-sectional view showing only the optical component of one telescope according to the second embodiment of the present invention. Four plane mirrors 24 are arranged at right angles to each other between the objective lens 21 and the eyepiece 22 to establish an image, It shows the state in which the optical axis of the eyepiece is moved outward than the optical axis of the objective lens. Here, as in the second embodiment, if a flat mirror is used instead of a poroprism, the weight can be reduced, the length of the barrel can be reduced, and manufacturing is easy. Of course, a system in which only one of the two poroprisms is replaced with a plane mirror is possible in consideration of the overall structure and function. In addition, there may be a method of using a loop prism instead of a poroprism to establish an image and spaced apart the optical axis of the objective lens from the optical axis of the eyepiece by using another total reflection prism or plane mirror. What is important is that the light source is divided up and down, and the distance between the eyebrows and the upper and lower light sources is similar to the distance between the left and right optical axes of the objective lens, which will be described later, from the forehead, and the distance between the left and right optical axes of the objective lens rather than the distance between the left and right optical axes of the headlight and the eyepiece. is that narrow binoculars must be combined.

7 shows a case in which the binoculars according to the third embodiment of the present invention are Galilean telescopes. In the Galilean telescope, the objective lenses 41 and 44 are convex lenses, and the eyepieces 43 and 46 are concave lenses. These Galilean telescopes are themselves upright. That is, there is no need for a sizing system to establish an image. However, in order to see a narrow hole, a system that narrows the distance between the optical axes of the left and right eyepieces rather than the distance between the optical axes of the left and right objective lenses is required. These systems can also use prisms or plane mirrors. The third embodiment of the present invention shows an example using a plane mirror among these systems. As described above, the reflected light from the bottom of the hole (0) travels along the optical axis of the objective lens (41, 44) made of a double-dotted line, is reflected by the two planar mirrors (42 or ) 45, and the optical axis of the eyepiece (43, 46) go into The combination of binoculars composed of such a telescope and a headlight with a light source dispersed up and down at a distance not far from the eyebrows is optimal for viewing and working in a narrow hole.
