Description

Embedded eyeglass device with adjustable magnifying lens

The invention relates to a pair of surgical spectacles, in particular to an embedded spectacles device with an adjustable magnifying lens.

Since human vision is limited, doctors' vision is no exception. Therefore, the appearance and fine structures that patients can see in clinical symptoms or any part of the body are limited. Therefore, in the medical field, doctors often use head-mounted surgical magnifiers to magnify their vision. Through optical auxiliary equipment that can magnify images, doctors can perform various medical treatments, surgeries or related disease diagnoses for patients, which helps to carry out various medical behaviors.

Please refer to FIG. 1 , which shows a commonly used head-mounted surgical magnifier 1. The head-mounted surgical magnifier 1 includes a lens body 11 and two magnification modules 12 disposed on the lens body 11, wherein the two magnification modules 12 are respectively fixed on the lenses of the lens body 11. After wearing the head-mounted surgical magnifier 1, the user (including a doctor) can clearly see tiny targets, so as to perform various precise medical procedures for the patient.

Although the prior art has provided a surgical magnifying glass, it still has the following disadvantages when actually used:

1. Prone to occupational hazards: The magnifying glass in the currently commonly used head-mounted surgical magnifying glass 1 does not have a bending structure, and the light cannot be refracted. The user needs to lower his head, bend his waist or squint during surgery. If worn for a long time, it will cause occupational injuries to the user's cervical spine, back, waist, etc.

2. Unable to change magnification: The medical field of surgery is different, and doctors will need magnifying glasses of different magnifications (for example, tooth correction requires about 3.5 times, but root canal or dental implants require 5 times or more). The currently commonly used head-mounted surgical magnifying glasses1 cannot change the magnification. If you need to use a different magnification, you need to purchase an additional pair of glasses, but a pair of medical magnifying glasses is often expensive, and the quantity plus the cost is a burden for users.

3. Unable to adjust the working distance: Currently, the commonly used head-mounted surgical magnifier 1 does not have a focusing mechanism, and the user cannot change the focal length or adjust the working distance of the magnifier, which makes it difficult to meet the needs of various different surgical fields.

4. Cannot be cleaned with liquid: All frame-embedded direct-view magnifiers on the market are not waterproof in their structural design. They can only be cleaned by wiping, not flushing. In the long run, surgical magnifiers are the dirtiest medical instruments in the operating room.

5. Unable to filter blue light: Most direct-view magnifying glasses do not have a blue light filter on the inside of the lens barrel. However, the use of LED lighting in medical settings is essential. If there is no blue light filter design inside the lens barrel, long-term use will cause eye damage to the user.

6. Complicated service: Because everyone's body structure is different, and no face is symmetrical, and no two people have the same distance between their eyes, early surgical magnifiers must be customized for the position of the eyes. Not only is the manufacturing cost high, but other people cannot use them. Frame-embedded direct-view magnifiers are customized and need to be confirmed with the doctor for individual usage data. Service personnel need to make an appointment with the doctor one-on-one, confirm the pupil distance, working distance, eye height, habitual tilt, etc. with the doctor on site, and then make a pair of magnifiers one by one. Produced based on the doctor's personal data, if the pupil distance measurement and working distance are confirmed incorrectly, or even if the usage habits change, changing the setting parameters means that the whole pair needs to be redone and returned to the foreign manufacturer. The service and production time and money spent are huge costs. The frame-embedded direct-view magnifier needs to be produced one by one according to the different customer requirements. The position of the lens inside the magnifier, the position of the magnifier embedded in the lens frame, the up and down and inside and outside angles of the magnifier embedded in the lens, etc., all need to rely on the operators to make them one by one, and the cost cannot be reduced.

7. Unable to install lighting tools: Although there are lighting tools on the operating table, the surgical location will vary with the incision, and some surgical locations cannot be fully illuminated. In addition, the early surgical magnifying glasses had a general spectacle frame, and the structure of the main frame must be relatively weak. It is difficult to install lighting tools on the main frame, and the user must wear a headlamp to provide lighting for the surgical location.

Therefore, how to design a surgical magnifying glass that can adjust the position of the magnifying glass so that it is aligned with the user's eyes, can adjust the tilt angle, and can also set a lighting tool is a goal that relevant technical personnel urgently need to work hard on.

The curved frame divides the mechanism into the frame surface and the front edge of the temples, and metal is placed at the end of the temples. It is lightweight, highly enveloping and functional. Users will not feel discomfort when wearing it for a long time. In actual implementation, other plastic materials can also be used, and this should not be limited to this.

The two lens frame accommodating portions 32 are used to limit the moving range of the two outer lens frame supporting bodies 41. In the first embodiment, the two lens frame accommodating portions 32 are two grooves arranged on the main supporting body 31. Two moving blocks 411 are respectively arranged on the two outer lens frame supporting bodies 41. The two moving blocks 411 are respectively arranged in the two lens frame accommodating portions 32 and can be moved in the two lens frame accommodating portions 32, so that the two outer lens frame supporting bodies 41 can be moved left and right relative to the main supporting body 31, thereby adjusting the left and right positions of the two magnifying glass modules 61.

The two position marking portions 35 are used to respectively mark the positions of the two external lens frame supporting bodies 41. In the second embodiment, the two position marking portions 35 are respectively arranged on the main supporting body 31 near the two lens frame accommodating portions 32, and the two position marking portions 35 are marked with scales and corresponding position values to indicate the left and right positions of the two external lens frame supporting bodies 41.

The two movable strap buckles 34 are respectively pivoted to the outer sides of the two mirror leg support bodies 33 to provide a shoulder strap (not shown in the figure) for the user to carry the embedded eyeglass device with an adjustable magnifying lens around the neck using the shoulder strap.

The two pivot bodies 39 are respectively disposed on the two mirror leg support bodies 33. The two pivot bodies 39 themselves have a pivot structure, which can make the two mirror leg support bodies 33 bend themselves to adjust the inclination angle of the two outer lens frame support bodies 41, thereby adjusting the inclination angle of the two magnifying glass modules 61. In some embodiments, the mirror leg mechanism can be adjusted through the two pivot bodies 39 to achieve an adjustment of about 15 degrees in three upper and lower sections, but it is not limited to this. In addition, the embedded eyeglass device with an adjustable magnifying glass can also be adjusted by a rotating mechanism hidden in the middle beam of the lens frame, and the inclination angle of the magnifying glass module 61 can be adjusted about 5 degrees inward or outward. In actual implementation, other inclination angles can also be adjusted, and this should not be limited to this.

The vertical rail hole 37 is disposed at the inner side of the main support body 31, and the second support body 51 is movably disposed in the vertical rail hole 37 to adjust the relative height of the second support body 51 relative to the main support body 31, thereby adjusting the height of the two outer lens frame support bodies 41 and the two magnifying glass modules 61. In the first embodiment, the second support body 51 is a nose pad structure. In actual implementation, the second support body 51 can also be other structures that can adjust the height of the two outer lens frame support bodies 41 and the two magnifying glass modules 61, and should not be limited to this.

The elastic fastener 36 is arranged on the inner side of the main support body 31 and is an elastic plastic structure. The inner lens frame support body 43 can be detachably assembled on the elastic fastener 36. Myopia lenses, hyperopia lenses, or other lenses for adjusting vision can be arranged in the inner lens frame support body 43. The two outer lens bodies 42 arranged in the two outer lens frame support bodies 41 have perforations. The two magnifying glass modules 61 are arranged in the perforations of the two outer lens bodies 42. The lenses arranged in the inner lens frame support body 43 can adjust the user's vision and make the user's vision clearer.

In the first embodiment, the front lens setting portion 38 is disposed at the top of the main support body 31. The front lens setting portion 38 is a snap-on structure. The front lens setting portion 38 can be provided with a front lens object (not shown in the figure). In some embodiments, the front lens object can be a lighting tool to provide light to the user during surgery. In actual implementation, the front lens object can also be other items, which should not be limited to this.

The main support body 31 is a lens frame, and its inner side appearance is a flat front curvature, with two inward-retracted sides. The arc-shaped lens leg support body 33 has a built-in bendable iron wire. The main support body 31 and the lens leg support body 33 can cover the head shape and balance the weight of the magnifying lens module 61. The main support body 31 is designed with an arc shape on the front frame surface to fit the head shape. The frame surface is concave on both sides. The purpose is to use the characteristics of TR material to have elasticity to clamp both sides of the forehead, disperse the weight of the magnifying lens module 61, and improve the problem of weight concentration on the nose bridge. The mirror leg support body 33 is the mirror leg. Its arc shape can fit the facial curve and disperse the weight. Finally, the adjustable mirror leg support body 33 is used to hook the head shape to increase the fit and coverage of the ears to achieve a five-point balance. The rear of the new mirror frame is also equipped with a strap, which allows the user to place the center of gravity further back to the back of the head when necessary to achieve the most burden-free wearing experience.

Please refer to Figure 5. The magnifying glass module 61 has an eyepiece component 611 connected to the outer lens body, a rhombus component 612 detachably connected to the eyepiece component 611, an objective lens component 613 detachably connected to the rhombus component 612, two window bodies 614 connected to the objective lens component 613, and a plurality of sealing rings 615.

The objective lens component 613 is provided with an adjustable telescopic structure for adjusting the length of the objective lens component 613 to change the magnification of the magnifying glass module 61. The two window bodies 614 are arranged in the objective lens component 613, and one of the window bodies 614 is close to the rhombus component 612. The two window bodies 614 are spaced apart from each other, and the spacing distance changes with the length of the objective lens component 613. The two window bodies 614 respectively close the opening of the objective lens component 613. Since the structure with adjustable magnification is a known technology, it will not be described in detail here. The two window bodies 614 can provide waterproof and dustproof functions for the objective lens component 613 and the rhombus mirror component 612 respectively.

A quick-release structure (not shown) is provided between the eyepiece component 611 and the rhombus component 612, which allows the eyepiece component 611 to be removed from the rhombus component 612 and replaced with another eyepiece component 611, so as to allow the user to replace lenses and adjust the user's vision, such as myopia, hyperopia, astigmatism, etc.

A screw structure 618 is provided between the rhombus component 612 and the objective lens component 613, so that the objective lens component 613 can be removed from the rhombus component 612 to be replaced with another objective lens component 613. The user can replace the magnifying glass module 61 with a different magnification by replacing the objective lens component 613 to cope with different surgical sites.

The plurality of sealing rings 615 are respectively arranged between the eyepiece component 611 and the rhombus component 612, between the rhombus component 612 and the objective lens component 613, and in the objective lens component 613. The sealing rings 615 are O-rings, which are respectively arranged in the quick-release structure between the eyepiece component 611 and the rhombus component 612, the screw structure 618 between the rhombus component 612 and the objective lens component 613, and the length-adjustable structure in the objective lens component 613. They can prevent moisture and water from entering the interior of the magnifying glass module 61 and also have a dust-proof effect.

Please refer to FIG. 5 and FIG. 6, wherein FIG. 6 is a partial enlarged view of the circle frame area in FIG. 5. The magnifying glass module 61 further includes an objective lens body 616 connected to the objective lens component 613, and a filter layer 617 connected to the objective lens body 616. The objective lens body 616 is the outermost transparent lens disposed in the objective lens component 613. The filter layer 617 is a coating coated on the surface of the objective lens body 616. The main purpose of the filter layer 617 is to filter blue light and protect the user's eyes. In actual implementation, the filter layer 617 can also use materials that filter other light waves, and should not be limited to this. Since the lighting in the operating room is strong and irradiates the surgical area for a long time, the blue light in the lighting light will damage the eyes of the doctor. The filter layer 617 effectively filters the blue light in the light to protect the user's eyes.

As mentioned above, the main innovative technologies of the magnifying glass module 61 of the new embedded eyewear device with adjustable magnifying glass are: 1. refractive optics; 2. replaceable objective lens; 3. adjustable working distance; 4. waterproof and dustproof; 5. blue light filtering; and 6. adjustable frame.

The key core technologies of the novel magnifying glass module 61 are:

1. Refraction optical path design simulation and modeling:

Traditional surgical magnifying glasses are "direct-view" optics, requiring only 1 convex and 1 concave lens to be assembled in the lens barrel, and the optical path design and processing are relatively easy. However, the new "refractive" product assembly requires an eyepiece component 611 (2 lenses, including 1 aspherical lens), a rhombus component 612, and an objective lens component 613 (2-3 lenses). The optical path from the objective lens to the eyepiece through the rhombus reflection is long and complex, and the design of a shared eyepiece is adopted. In order to have high-quality imaging, the optical path precision of the design simulation must be very high and needs to be repeatedly corrected.

2. Glass processing and coating:

To obtain high-quality images, the curvature of the glass processing must be precise, and additional anti-reflective coating treatment and the use of aspherical lenses are required during manufacturing to correct aberrations and chromatic aberrations.

3. Appearance and structure design, processing and assembly:

The external structure of the magnifying glass module 61 is divided into an objective lens mechanism, a rhombus lens mechanism, and an eyepiece mechanism. In addition to innovative functionalities such as a replaceable objective lens, waterproof and dustproof, and adjustable working distance, the processing precision requirements of the above three sets of external mechanisms must also be very high to ensure that the overall tolerance after assembly between the lens group and the mechanism group does not affect the original optical path design, and retains the functions of replacing the objective lens, waterproofing, dustproofing, and adjusting the working distance.

4. Development and design of multifunctional mirror frames:

The biggest highlight of the development of the multifunctional frame with an embedded eyeglass device with an adjustable magnifying lens is that it reduces the cost of customization while meeting the needs of customization. The multifunctional frame has the following key functions: (1) adjustable pupil distance; (2) adjustable internal and external tilt; (3) adjustable pupil height; (4) adjustable vertical tilt; (5) lightweight; and (6) good wrapping. However, the reliability and weight of the above functions combined with the frame require constant adjustment and testing.

The optical imaging method of the magnifying glass module 61 is composed of an eyepiece component 611, a rhombus component 612, and an objective lens component 613. After the object image reaches the rhombus (not shown in the figure) of the rhombus component 612 from the object lens body 616 of the objective lens component 613, it will be refracted to the eyepiece (not shown in the figure) of the eyepiece component 611 to form an image. The rhombus can change the direction of light. The user does not need to lower his head during surgery, but only needs to look straight ahead to see the image below.

The magnifying glass module 61 is provided with 3.5x and 5x objective lenses, wherein the eyepiece component 611 and the rhombus component 612 are shared at each magnification. By replacing objective lenses of different magnifications, the magnification can be changed. Since the 5x objective lens has a higher magnification, the optical path length of the objective lens is longer than that of 3.5x, the optical path design is more complicated, and the lenses used are more than that of 3.5x. In actual implementation, the magnifying glass module 61 can also use other magnifying glass structures, and should not be limited to this.

Since the use environment may be contaminated by dust, dirt, and even blood, cleaning and washing are very important to keep the inside of the magnifying glass module 61 clean. Therefore, the eyepiece component 611 and the objective lens component 613 in the magnifying glass module 61 are each designed with multiple rubber sealing rings 615 (O-rings) of different sizes, with three O-rings inside and one O-ring inside the eyepiece component 611. The compact mechanism design can achieve a high level of waterproof and dustproof effect.

The anti-blue light film coated in the magnifying glass module 61 can filter out blue light above the 450-wavelength band. In other words, it reflects the light in the 450-wavelength band and transmits the light outside the 450-wavelength band, so that the light received by the user's eyes does not have the light in the 450-wavelength band. In terms of processing, the glass will first be roughed and then finely ground and subsequently coated. Due to the increase in LED lighting equipment in modern environments, the blue light in the lighting will harm the eyes, especially when using a magnifying glass. Therefore, the lens in the magnifying glass module 61 will be added with a blue light filtering and anti-reflection coating process. Among them, the glass will need to open 5 sets of molds, including 3.5 times grinding and polishing molds, 3.5 times coating frame molds, eyepiece aspherical injection molding molds, 5 times grinding and polishing molds, 5 times coating frame molds, etc.

The design of the new embedded eyewear device with adjustable magnifying lens must take into consideration the comfort of wearing and the balance of weight, and the functionalities of adjustable pupil distance, pupil height, inclination angle, and vertical tilt angle are added.

Please refer to Figures 7, 8 and 9, which are a second embodiment of the new embedded eyeglass device with an adjustable magnifying lens. The second embodiment is substantially the same as the first embodiment, and the similarities are not described in detail here. The difference is that the material of the main support body 31 and the two mirror leg support bodies 33 is selected from metal materials. In some embodiments, the material of the main support body 31 and the two mirror leg support bodies 33 is titanium alloy, which has very good elasticity and can be bent by the user. In actual implementation, other metal materials can also be used, and should not be limited to this.

The front-lens setting portion 38 is arranged on the front side of the main support body 31, and can provide a front-lens object (not shown in the figure) for setting, wherein the main support body 31 is provided with a plurality of fixing holes, and the front-lens setting portion 38 can be fixed in the fixing holes by using fixing columns. The front-lens setting portion 38 can adjust the height to adjust the height of the front-lens object relative to the main support body 31.

In the second embodiment, the frame receiving portion 32 is not only a groove provided on the main support body 31, but also has a top opening 321 provided on the top of the main support body 31, a plurality of side openings 322 provided on the inner side of the main support body 31, and a bottom opening 323 provided on the bottom of the main support body 31. The number of the side openings 322 can be one, but should not be limited thereto. The top opening 321, the side openings 322, and the bottom opening 323 are connected.

7, 8, and 10, the outer frame support body 41 has a moving block 411 and a plurality of adjustment components 412 disposed on the moving block 411. The moving block 411 is disposed in the frame receiving portion 32 from the bottom opening 323. The plurality of adjustment components 412 are respectively disposed from the top opening 321 and the side opening 323. 322 is exposed to the outside, and the moving block 411 can move left and right in the frame accommodating portion 32 to adjust the position of the two external lens frame supporting bodies 41 relative to the main supporting body 31. The adjusting assembly 412 can display the position of the two external lens frame supporting bodies 41, and can also provide the user with the ability to adjust the position of the two external lens frame supporting bodies 41, thereby providing the user with the ability to adjust the pupil distance.

Referring to FIG. 9 and FIG. 11 , in the second embodiment, the second supporting body 51 has a cross bar 511 detachably disposed on the main supporting body 31, two supporting bars 512 disposed on both sides of the cross bar 511 and extending downward, and two pads 513 disposed at the bottom of the two supporting bars 512, wherein the main supporting body 31 is provided with a plurality of fixing holes, and the second supporting body 51 The cross bar 511 is provided with a through hole, and the second support body 51 uses a plurality of fixing columns to fix the cross bar 511 to the main support body 31. The plurality of fixing holes have a height difference for adjusting the height of the second support body 51 relative to the main support body 31, thereby adjusting the height of the two outer lens frame supports 41 and the two magnifying glass modules 61, so as to adjust the nose bridge mechanism and adjust the pupil height.

In the second embodiment, the outer lens body 42 disposed in the two outer lens frame supporting bodies 41 is also provided with through holes, and the two magnifying lens modules 61 are disposed in the through holes of the two outer lens bodies 42 .

From the above description, it can be seen that the new embedded eyeglass device with adjustable magnifying lens has the following effects:

1. Refraction application technology: Dentists and surgeons often perform operations for two to three hours or more. Wearing ordinary magnifying glasses for a long time will cause neck pain. In the embedded eyeglass device with adjustable magnifying glasses, the common rhombus component 612 for deflecting the optical path, the common eyepiece component 611, and the objective lens component 613 with different magnifications allow users to see the magnified image below by simply looking straight ahead. The magnified image can be clearly seen without bending the neck, which can alleviate long-term occupational injuries of doctors.

2. Magnifying glasses with replaceable magnification: Currently, the magnification of magnifying glasses on the market is fixed. The embedded eyeglass device with adjustable magnifying glasses has a design for replacing the magnification of the magnifying glasses. The eyepiece component 611 and the diamond mirror 612 are shared in each magnification state. By replacing the eyepiece component 613 with different magnifications, the function of changing the magnification is provided. The user can freely replace the required magnification, which not only improves the flexibility of use but also reduces the user's purchase cost.

3. Adjustable working distance: The structure of the embedded eyewear device with an adjustable magnifying lens is designed with a focusing mechanism, which shares the eyepiece component 611. By changing the length of the objective lens component 613, the working distance can be adjusted to meet the various conditions and different situations of the user.

4. Waterproof and dustproof design: Currently, almost all magnifying glasses in the world are not waterproof and dustproof. They can only be wiped on the surface with water and cannot be rinsed. The embedded eyeglass device with an adjustable magnifying glass is designed with a sealing ring 615 (O-ring) with high temperature sterilization level and the two window main bodies 614, and combined with high-precision processing design, it can achieve the effect of waterproof and dustproof.

5. Filter blue light to protect eyes: Currently, there are LED surgical lights in all surgical fields. The incision of the upper and lower surgery is small, and most doctors will also wear LED headlights. If the lens barrel of the magnifying glass does not have the function of filtering blue light, the doctor's eyes may be directly exposed to blue light for a long time through the magnifying glass, which may cause eye problems. The lens of the new embedded eyeglass device with adjustable magnifying glass is provided with a filter layer 617 for filtering blue light, which effectively protects the user's eyes.

6. Adjustable frame: Generally, medical magnifying glasses are customized products. However, after customization, due to user habits or incorrect data provided, the magnified image may not be clearly seen or even overlapped, and the glasses must be remade, wasting money and time. The two moving blocks 411 are respectively arranged in the two frame receiving parts 32, and can be moved in the two frame receiving parts 32, so that the two outer frame support bodies 41 can move left and right relative to the main support body 31, thereby adjusting the left and right positions of the two magnifying glass modules 61. The second support body 51 is movably arranged in the vertical rail hole 37 to adjust the The heights of the two outer lens frame supports 41 and the two magnifying glass modules 61 are such that the positions of the two magnifying glass modules 61 match the positions of the user's eyes. The two pivot bodies 39 are respectively disposed on the two lens leg supports 33. The two pivot bodies 39 themselves have a pivot structure, which can bend the two lens leg supports 33 to adjust the inclination angle of the two outer lens frame supports 41, thereby adjusting the inclination angle of the two magnifying glass modules 61.
