BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical loupe apparatus, and more specifically, as a pair of magnifiers mounted on glasses are flipped up and down, it is possible to freely switch between a general view and an enlarged view. A flip-up type medical loupe device, which relates to a flip-up type medical loupe device, which can easily adjust the distance between magnifying glasses according to the distance between two eyes of a user.

In general, the loupe apparatus is a generic term for a lens device that has a short focal length to view an enlarged virtual image of an object, but is generally used for fine work such as watch repair and jewelry, or during medical work such as surgery. In other words, it refers to a compact converging lens device that enlarges details that are hard to see with the naked eye.

Surgical loupe apparatus should be able to be worn and used for a long time, and in spite of frequent change of eyes during surgery, it is necessary to magnify and display various objects located within a predetermined distance. Because of this, a typical medical loupe device is either a flip up or through the lens type with a magnifier in separate glasses or a magnifier in a head band. It represents the head band type, and the simple view of turning the head by constantly fixing the magnifying glass in front of the user through glasses or the headband provides a magnified view of various objects located within a certain distance. can see.

1 is a perspective view showing a so-called flip-up type as an example of a general medical loupe device.

As can be seen, a typical flip-up type medical loupe consists of glasses 10 and a loupe assembly (20) mounted thereon, of which glasses 10 serve as a frame to be placed on the user's face. It consists of a spectacle frame 12 and left and right spectacle lenses 16 and 18 fixed thereto and placed in front of the eyes of the user. The loupe assembly 20 is a bar-shaped loupe frame 22 that is hinged to the spectacle frame 14 so as to cross the front of the left and right eyeglass lenses 16 and 18, and is coupled to the lower ends of both sides thereof. And a pair of first and second magnifying glasses 36 and 38 arranged in front of the left and right eyeglass lenses 16 and 18. In this case, at least one lens is embedded in each of the first and second magnifying glasses 36 and 38 to show an enlarged virtual image of the object.

Therefore, when the user wears the glasses 10, the user can see an enlarged view of the object through the left and right eyeglass lenses 16 and 18 and the first and second magnifying glasses 36 and 38. As the first and second magnifying glasses 36 and 38 move away from the line of sight, the general field of view may be viewed through the left and right eyeglass lenses 16 and 18.

That is, the general flip-up type medical loupe exhibits a structural feature capable of flipping a pair of magnifying glasses 36 and 38 up and down according to a user's selection, and the first and second magnifying glasses 36 and 38 respectively have left and right glasses. Compared to the through lens type, which is permanently penetrated and fixed to the lenses 16 and 18, the tilt angles of the first and second magnifying glasses 36 and 38 can be freely adjusted to reduce neck pain. There is an advantage that can secure a relatively wide general field of view.

Looking at the general flip-up type medical loupe in more detail, the hinge end 24 of the predetermined length protrudes in the center of the loupe frame 22, the hinge connection (hinge bracket: 14) provided on the spectacle frame 12 On both sides of the loupe frame 22, first and second adjustment screws 32, through which first and second long holes 26 and 28 having a slit shape extending in the longitudinal direction, penetrate and are inserted, respectively, The first and second magnifying glasses 36 and 38 are fixed through 34.

Therefore, after the user wears the glasses 10, the user loosens the first and second adjustment screws 32 and 34 to adjust the distance between the first and second magnifiers 36 and 38, and then adjusts the first and second adjustments. By tightening the screws 32 and 34, the distance between the two magnifying glasses 36 and 38 can be fixed.

However, the general flip-up type medical loupe exhibits some inconveniences. As one of them, the process of adjusting the interval between the first and second magnifying glasses 36 and 38 is cumbersome and inconvenient.

That is, in the general flip-up type medical loupe, in order to adjust the gap between the first and second magnifiers 36 and 38, the first and second adjustment screws 32 and 34 are loosened and then each magnifier 36, 38), then retighten the first and second adjustment screws (32, 34) is essential, which is cumbersome because the process must be repeated for each user, and both hands are mobilized during this process. There is a discomfort that can not.

In addition, since the distance from the spectacle frame 12 to the first and second magnifiers 36 and 38 is fixed, the general flip-up type medical loupe may fix the first and second magnifiers 36 to the left and right spectacle lenses 16 and 18. (38), the imaging position is fixed, and therefore, when the first and second magnifying glasses 36, 38 are not placed correctly in front of the user's eyes, there is a disadvantage of forcibly raising or lowering the glasses.

That is, the general flip-up type medical loupe can only flip the entire loupe assembly 20 up and down, and in the enlarged view state, the first and second magnifying glasses 36 and 38 separate from the left and right eyeglass lenses 16 and 18. There is no way to move it. However, according to the user, the wearing height of the glasses including the eye height is different from each other. Currently, when the first and second magnifying glasses 36 and 38 are not placed correctly in front of the left and right eyes, the glasses 10 are unnaturally raised or lowered. There are various inconveniences, such as the need to use or fix it with a separate adhesive tape.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to present a specific method that can more easily adjust the interval between the first and second magnifying glasses according to the distance between the eyes of the user.

In addition, another object of the present invention is a flip-up type medical loupe that can be used without any inconvenience even if the eye height of the user or the wearing height of the glasses are different, so that the image position of the first and second magnifying glasses with respect to the left and right eyeglass lenses can be adjusted freely up and down. The purpose is to provide.

In order to achieve the above object, the present invention is a flip-up type medical loupe comprising a pair of spectacle frame and the left and right eyeglass lens, the loupe frame connected to the hinge and the eyeglass frame so as to cross the left and right eyeglass lens; A joint interposed between both ends of the loupe frame; First and second pins threaded through opposite ends of the loupe frame so as to face each other in a straight line and screwed in opposite directions to both ends of the joint; A first and second magnifiers coupled to the first and second pins and disposed on the front of the left and right eyeglass lenses, and the flip between the first and second magnifiers increases or decreases according to the rotation direction of the joint; Provides an up type medical loupe.

At this time, the loupe frame is provided with a turnbuckle space rotatably mounted to the joint, the joint is characterized in that the outer surface is a roulette cylindrical shape, the hinge is connected to each of the spectacle frame and the loupe frame and It characterized in that it further comprises one or more connector pins for connecting the loupe frame, the connector pins are characterized in that two or more hinged to each other.

In addition, the first and second guide holes penetrated in the slit shape along both longitudinal directions of the loupe frame; And first and second adjusting screws inserted into the first and second pins through the first and second guide holes with a clearance therebetween, and penetrating the first and second pins, respectively. And then inserted into the first and second magnifying glass, characterized in that it further comprises a third and fourth adjusting screw for coupling the first and second magnifying glass to the first and second pins, respectively.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 and 3 are a perspective view and an exploded perspective view showing an example of a flip-up type medical loupe (hereinafter, simply referred to as medical loupe) according to the present invention, respectively, for convenience of the glasses 50 and the loupe mounted thereto. It can be divided into an assembly (60).

First, the eyeglasses 50 are composed of a frame 52, which serves as a frame to be worn on the wearer's ear and nose, and the left and right eyeglass lenses 56 and 68 fixed thereto and placed in front of the user's eyes. . At this time, if necessary, the eyeglasses 50 may have the form of goggles or other goggles, and the left and right eyeglass lenses 56 and 58 may represent a frequency suitable for a user's vision.

Next, the loupe assembly 60 is a bar-shaped loupe frame 62 hinged to the spectacle frame 52 so as to cross the front of the left and right spectacle lenses 56 and 58, and the left and right spectacle lenses fixed to both lower ends thereof. (56,58) consisting of first and second magnifying glasses 86,88 placed on their respective front surfaces. At this time, at least one lens is embedded in each of the magnifying glasses 86 and 88 to show an enlarged image of the object.

Therefore, when the glasses 50 are worn, the enlarged view of the target object can be seen as the left and right eyeglass lenses 56 and 58 and the first and second magnifying glasses 86 and 88 are placed in front of the eyes of the user. In addition, when the loupe frame 62 is bent up so that the first and second magnifying glasses 86 and 88 are out of view, the general field of view may be viewed through the left and right spectacle lenses 56 and 58.

At this time, the medical loupe according to the present invention can easily adjust the interval between the first and second magnifying glasses (86,88), and the first and second magnifying glasses (86,88) for the left and right eyeglass lenses (56,58) It is characterized in that it is possible to freely adjust the imaging position of the bar, the first and second magnifying glass (86,88) for the former represents a coupling structure of the turnbuckle (turnbuckle) via the loupe frame 62, For the latter, the spectacle frame 52 and the loupe frame 62 represent a multi-axis link connection structure by hinge connection.

Look at each one in detail.

First, the medical loupe according to the present invention adopts a turnbuckle or similar coupling structure so that the distance between the first and second magnifying glasses 86 and 88 can be easily adjusted. In this case, 'turn buckle' refers to a connecting part used for pulling or slowing a support wire rope, etc., and a pair of threads provided with opposite left and right threads at both ends of a joint having a common nut. A pin is screwed together. Therefore, the distance between the two pins can be far or narrow depending on the rotation direction of the joint.

Accordingly, the medical loupe according to the present invention penetrates both ends of the joint 76 interposed between both ends of the loupe frame 62 and both ends of the loupe frame 62 so as to face each other in a straight line. First and second pins 72 and 74 are screwed in opposite directions to the left and right, and the first and second magnifying glasses 86 and 88 are attached to the first and second pins 72 and 74, respectively. I'm joining. Therefore, the distance between the first and second magnifiers 86 and 88 including the first and second pins 72 and 74 is adjusted according to the rotation direction of the joint 76. The user rotates the joint 76. By the operation alone, the distance between the first and second magnifying glasses 86 and 88 can be matched to the distance between the two eyes.

More specifically, Figure 4 is a partial cross-sectional view of the medical loupe according to the present invention, in particular showing a cross-section of the first and second pins 72, 74, including the loupe frame 62.

2, 3, and 4, the medical loupe according to the present invention includes a loupe frame having first and second pins 72 and 74 having left and right threads 72a and 74a opposite to each other at one end thereof. While inserted through both ends of the (62) to face in a straight line, between the first and second pins (72, 74) through the joint 76, the first and second pins (72, 74) are each screwed in. At this time, the screw hole (76a) in the longitudinal direction is passed through the joint 76, the opposite ends are provided with separate left and right threads (76b, 76c) opposite each other. The first and second magnifying glasses 86 and 88 are fixed to the other ends of the first and second pins 72 and 74, respectively.

As a result, the joint 76 and the like including the first and second pins 72 and 74 adopted in the medical loupe according to the present invention exhibit a structure and a working relationship similar to the turnbuckle, and the joint 76 in any one direction. Rotating the first and second pins 72, 74 away from each other to open the gap between the first and second magnifying glasses 86, 88, and rotating the joint 76 in the opposite direction, the first and second pins The 72 and 74 are closer to each other, and the interval between the first and second magnifying glasses 86 and 88 is narrowed.

At this time, although not shown in the drawings, instead of passing through the screw holes in the opposite directions to each of the first and second pins 72 and 74, the shafts having opposite threads to both ends of the joint 76 are provided. It may be extended to penetrate both ends of the loupe frame 62, and then screwed into the first and second pins 72 and 74. The operation is performed by rotating the joint 76 in the same manner as before. The spacing between the first and second magnifying glasses 86, 88, including the second pins 72, 74, increases or decreases. That is, the biggest feature of the medical loupe device according to the present invention is to apply the principle of the turnbuckle, to adjust the interval between the first and second magnifying glasses (86, 88) only by the operation of rotating the joint 76, Details of the joint 76 and both ends thereof as long as they are essential components of the first and second pins 72 and 76, which are screwed in opposite directions to each other and the first and second magnifying glasses 86 and 88 coupled thereto, respectively. The form can be changed as much as possible.

In addition, if necessary, as shown in the drawing, a separate turnbuckle space 70 may be provided in the loupe frame 62 so that the joint 76 may be rotatably mounted, and the joint 76 may be a roulette on a cylindrical outer surface. ) It is desirable to increase the frictional force by providing unevenness by processing. Accordingly, the user can more easily adjust the distance between the first and second magnifying glasses 86 and 88 by rotating the joint 76 exposed from the turnbuckle space 70 with a finger or the like.

Furthermore, the slit-shaped first and second guide holes 66 and 68 pass through both longitudinal directions of the loupe frame 62, and the first and second guide holes 66 and 68 are spaced apart. The first and second adjusting screws 92 and 94 can be inserted into the first and second pins 72 and 74 so that the first and second adjusting screws 92 can be rotated by rotating the joint 76. The first and second pins 72 and 74 are moved together with the first and second pins 72 and 74 while being guided by the first and second guide holes 66 and 68, respectively. Of the first and second magnifiers (92,94) by tightening the first and second adjustment screws (92,94) when the first and second magnifying glasses (86,88) reach their proper positions. ) Position can be fixed. In this case, the first and second guide holes 66 and 68 may penetrate the bottom surface of the loupe frame 62 so that the first and second adjusting screws 92 and 94 may be inserted from the bottom upwards, respectively. .

In addition, in order to couple the first and second magnifying glasses 86 and 88 to the first and second pins 72 and 74, respectively, the first and second pins 72 and 74 pass through the first and second pins 72 and 74, respectively. Third and fourth adjusting screws 82 and 84 inserted into the second magnifying glass 86 and 88 may be used, and if necessary, the third and fourth adjusting screws 82 and 84 may be rotated to rotate the first and second adjusting screws 82 and 84. It is also possible to rotate the magnifying glasses 86,88.

Next, the medical loupe according to the present invention is characterized in that the imaging position of the first and second magnifying glasses 86 and 88 with respect to the left and right spectacle lenses 56 and 58 can be adjusted up and down. ) And one or more connector pins 102 and 104 hinged to the loupe frame 62, respectively.

5 is an enlarged view illustrating the inside of the circle of FIG. 2. Referring to the case where two connector pins 102 and 104 are used as shown in FIGS. 2, 3, and 5, the first and second connector pins 102 and 104 are used. Are hinged to each other to represent the hinge frame connected to the spectacle frame 52 and the loupe frame 62, respectively. At this time, the hinge frame 54 may be provided on the spectacle frame 52, and the hinge end 64 may protrude from the loupe frame 62.

That is, the first connector pin 102 hinged to the hinge bracket 54 of the spectacle frame 52 by the first hinge shaft s1 is hinged to the second connector pin 104 by the second hinge shaft s2. The second connector pin 104 is hingedly connected to the hinge end 64 of the loupe frame 62 by a third hinge axis s3. Accordingly, the first connector pin 102 is tilted up and down with respect to the hinge bracket 54 with respect to the first hinge axis s1, and the second connector pin 104 is formed with reference to the second hinge axis s2. The first connector pin 102 is flipped up and down, and the hinge end 64 of the loupe frame 62 is flipped up and down relative to the second connector pin 104 based on the third hinge axis s3.

Therefore, by adjusting the degree of each of these, the entire loupe assembly 60 can be moved up and down with respect to the spectacle frame.

In this case, although not shown in a separate drawing, two hinge shafts appear when one connector pin is used, and four hinge shafts appear when three connector pins are used. On the other hand, the width of the up and down movements increases, so it may be sagging due to its own load. Therefore, it is preferable to use two to three connector pins.

Thus, after the user wears the glasses 50, the user properly adjusts the distance between the upper and lower positions of the loupe assembly 60 and the first and second magnifiers 86 and 88 so that the first and second magnifiers 86 are placed in front of both eyes. , 88) can be exactly matched.

In summary through the use method for the medical loupe according to the present invention described above, the user wears the medical loupe according to the present invention by the operation of wearing glasses (50). Thereafter, by rotating the joint 76 with a finger or the like, the distance between the first and second magnifying glasses 86 and 88 is adjusted to be suitable for the binocular spacing, and if necessary, the first and second adjusting screws 92 and 94 are adjusted. Tightening can fix the gap between the first and second magnifying glasses 86,88. The user can also align the first and second magnifying glasses 86 and 88 in the desired direction using the third and fourth adjusting screws 82 and 84, respectively, via the first and second connector pins 102 and 104. The entire loupe assembly 60 linked by the multi-axis hinge to the spectacle frame 52 can be moved up and down to accurately position the first and second magnifying glasses 86 and 88 in front of both eyes.

As described above, the medical loupe according to the present invention has an advantage of easily adjusting the interval between the first and second magnifying glasses according to the distance between two eyes of the user. In addition, the medical loupe according to the present invention can freely adjust the imaging position of the first and second magnifiers with respect to the left and right eyeglass lenses, and thus can be used without any inconvenience even if the eye height of the user or the wearing height of the glasses are different. have.
