Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary instruments, in particular to an instrument for measuring the tilt angle of eyes. Background Art

[0002] The eye, also known as the eye or the iris, is the organ that most animals use to receive light and form images in the brain. For humans, the eye is one of the most important sensory organs and the most visible part of the human body. Aestheticians call it the window to the soul, so beautiful eyes often add the finishing touch to a person's appearance. Everyone cherishes beauty. However, the beauty of eyes isn't solely determined by whether they have a single or double eyelid. Many factors influence their appearance and demeanor. Besides eye length, height, and the degree of iris exposure, another crucial indicator is the angle of the eye, also known as palpebral fissure inclination. Palpebral fissure inclination refers to the angle between the line connecting the inner and outer corners of the eye and the horizontal line.

[0003] The inclination of the palpebral fissure can also be adjusted through plastic surgery. Before performing eye plastic surgery, the inclination of the palpebral fissure needs to be accurately measured. However, some measuring instruments on the market cannot accurately measure the exact data of the inclination of the palpebral fissure, which often leads to the failure of plastic surgery. Therefore, we propose an instrument for measuring the inclination angle of the eye to solve the above problem. Summary of the Invention

[0004] In view of the deficiencies raised in the above background technology, the present invention provides an instrument for measuring the tilt angle of the eye.

[0005] The utility model adopts the following technical solutions:

[0013] As a further improvement, an axial hole is provided at the right end of the measuring skeleton, and a rotating shaft is provided at the head end of the measuring rod. The rotating shaft is arranged to rotate in the axial hole, and the rotating shaft is made of a transparent material.

[0014] As a further improvement, a slide groove is passed through the front of the ruler, and a sliding shaft is provided at the end of the measuring rod. When the measuring rod rotates, the sliding shaft slides in the slide groove, and the handle is provided at the top of the sliding shaft to extend and retract, and the diameter of the handle is larger than the width of the slide groove.

[0015] As a further improvement, a threaded hole is provided on the top of the sliding shaft, an inwardly recessed mounting groove is provided on the end face of the handle head, and a mounting hole is provided on the end face of the handle tail that passes through the mounting groove.

At this time, the scale value pointed to by the pointer on the handle on the ruler is the inclination angle of the eye, that is, the inclination of the palpebral fissure. During the process, the level of the measuring skeleton is detected by the spirit level, so that the measuring skeleton can be kept level when measuring the inclination of the palpebral fissure, avoiding the tilt of the measuring skeleton affecting the accuracy of the palpebral fissure inclination measurement result.

[0027] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0028] As attached Figure 1 and Figure 2As shown, an instrument for measuring the eye inclination angle includes a measuring skeleton 1, a ruler 2, a measuring rod 3, a handle 33 and a level 4.

[0029] As attached Figure 2 、 Figure 3 、 Figure 4 and Figure 8 As shown, a scale 2 is fixed to the left end of the measuring skeleton 1. The scale 2 is a fan-shaped structure, and a scale 22 is provided on the front of the scale 2. The right end of the measuring skeleton 1 is hinged to the head end of the measuring rod 3, and the end of the measuring rod 3 is provided on the scale 2 for sliding. A handle 33 is provided on the end of the measuring rod 3 for moving the measuring rod 3. Specifically, an axial hole 11 is opened at the right end of the measuring skeleton 1, and a rotating shaft 31 is provided at the head end of the measuring rod 3. The rotating shaft 31 is provided and rotates in the axial hole 11. The 0 scale line of the scale 22 on the scale 2 is on the same horizontal line as the axis of the rotating shaft 31 to facilitate subsequent readings. At the same time, a slide groove 21 is passed through the front of the scale 2, and a sliding shaft 32 is provided at the end of the measuring rod 3. A handle 33 is provided at the top of the sliding shaft 32. When the measuring rod 3 rotates, the sliding shaft 32 is provided in the slide groove 21. When in use, the measuring frame 1 is placed horizontally in front of the eyes, so that the rotating shaft 31 is aligned with the inner corner of the eye, and then the measuring rod 3 is rotated by the handle 33 until the measuring rod 3 is aligned with the outer corner of the eye. At this time, the value of the scale 22 on the ruler 2 that the end of the measuring rod 3 is aligned with is read, which is the eye tilt angle, that is, the inclination of the palpebral fissure. Among them, the setting of the handle 33 can facilitate the rotation of the measuring rod 3, so that the fingers can be kept away from the eyes when rotating the measuring rod 3, avoiding scratches on the eyes and injuring the eyes or surrounding skin. The width of the measuring rod 3 can be reduced as much as possible, making it convenient to read the value while reducing measurement errors. In addition, a pointer 34 can be set on the outer side of the end of the handle 33, and the pointer 34 points to the scale 22. When reading the measurement value of the measuring rod 3, the value of the scale 22 on the ruler 2 that the pointer 34 is aligned with is used as the standard, which can also effectively reduce the reading error of the value and make the measurement result more accurate.

[0030] It is worth mentioning that, as Figures 5 to 8As shown, the handle 33 can be mounted on top of the sliding shaft 32 of the measuring rod 3 and can be extended and retracted. Specifically, a threaded hole 321 is provided at the top of the sliding shaft, an inwardly recessed mounting groove 331 is provided on the front end of the handle 33, and a mounting hole 332 is provided on the rear end of the handle 33 that extends through the mounting groove 331. During installation, the rear end of the handle 33 is placed on top of the sliding shaft 32, and the screw 351 of the screw 35 is passed through the mounting groove 331 and the mounting hole 332 in sequence before being tightened into the threaded hole 321, thereby connecting the handle 33 to the sliding shaft 32. At this point, the handle 33 slides over the outside of the screw 35. Furthermore, a spring 36 is provided within the mounting slot 331. When the screw 351 is screwed into the threaded hole 321, the screw 351 passes through the interior of the spring 36. When the screw 351 is then tightened into the threaded hole 321, the two ends of the spring 36 respectively press against the bottom of the mounting slot 331 and the surface of the screw head 352 of the screw 35. The screw head 352 then compresses the spring 36, pressing the handle 33 against the front of the scale 2. During measurement, the handle 33 can be pulled outward along the screw 35, further compressing the spring 36 and releasing it from the front of the scale 2, ensuring smooth rotation of the measuring rod 3. After measurement, the handle 33 can be released. The elastic restoring force of the spring 36 then re-presses the handle 33 against the front of the scale 2, securing the measuring rod 3 and preventing it from sliding down. This facilitates adjustment of the measuring rod 3's position during subsequent repeated measurements and inspections, thereby ensuring the accuracy of the measured data and facilitating accurate subsequent readings. The diameter of the handle 33 is larger than the width of the slide groove, ensuring that the handle 33 can be pressed against the front of the ruler 2 under the elastic force of the spring 36 to fix the measuring rod 3.

[0031] In addition, as attached Figures 5 to 7 As shown, the screw 35 has a fixing portion 353 with a regular polygonal cross-section disposed between the screw head 352 and the screw rod 351. The mounting hole 332 is adapted to the fixing portion 353. When the handle 33 slides on the outside of the screw 35, the mounting hole 332 slides on the outside of the fixing portion 353. The corners of the fixing portion 353 limit the sliding direction of the handle 33, preventing the handle 33 from rotating during the sliding process, which would cause the pointer 34 on the handle 33 to not accurately point to the scale 22. Furthermore, the diameter of the screw head 352 is larger than the diameter of the mounting slot 331. This not only limits the sliding distance of the handle 33, preventing the handle 33 from excessively compressing the spring 36 during sliding, thereby shortening the service life of the spring 36, but also reduces the risk of the spring 36 detaching from the screw head 352 and ultimately falling out of the mounting slot 331 during use.

[0032] In addition, as attached Figure 2 and Figure 8As shown, the measuring frame 1 is provided with a spirit level 4, which can specifically be a bubble level. The principle of a bubble level is to use the property of an air bubble in a glass tube, which always remains at the highest position, to verify the levelness of the mounting surface. During use, the spirit level 4 checks the levelness of the measuring frame 1, ensuring that the measuring frame 1 is level when measuring the eye fissure inclination, and preventing the measuring frame 1 from tilting and affecting the accuracy of the eye fissure inclination measurement results.

[0033] Among them, as attached Figure 2 and Figure 4 As shown, the measuring skeleton 1, the ruler 2, the rotating shaft 31 and the measuring rod 3 are all made of transparent materials, specifically transparent plastic or glass. Instruments made of transparent materials can, on the one hand, observe the eyes and the surrounding areas of the eyes at any time to avoid hurting the eyes or the surrounding skin, and on the other hand, avoid hindering the use of the instrument and the reading of measurement data.

[0034] In summary, when the present invention is used, the measuring skeleton 1 is placed horizontally in front of the eyes, so that the hinge point between the measuring skeleton 1 and the measuring rod 3 is aligned with the inner corner of the eye, and then the measuring rod 3 is toggled by the handle 33 so that the measuring rod 3 is aligned with the outer corner of the eye. At this time, the value of the scale 22 pointed to by the pointer 34 on the handle 33 on the ruler 2 is the eye tilt angle, that is, the inclination of the palpebral fissure. During the process, the level of the measuring skeleton 1 is detected by the level 4, so that the measuring skeleton 1 can be kept level when measuring the inclination of the palpebral fissure, avoiding the tilt of the measuring skeleton 1 affecting the accuracy of the palpebral fissure inclination measurement result. After the measurement, the handle 33 can be retracted and pressed against the front of the ruler 2 to fix the measuring rod 3 and prevent the measuring rod 3 from sliding down, making it convenient to adjust the position of the measuring rod 3 during subsequent repeated measurements and inspections, thereby ensuring the accuracy of the measurement data and facilitating accurate readings later. The utility model accurately measures the accurate data of the inclination of the palpebral fissure through the mutual cooperation between the measuring skeleton 1, the measuring rod 3, the ruler 2, the handle 33 and the level 4, so as to make preoperative preparations for plastic surgery and ensure the smooth progress of the plastic surgery. The measuring steps are simple and easy to use.

[0035] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
