Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an eyeball marker ruler. Background Technology

[0002] Ophthalmology, short for "eye disease specialty," is the study of diseases affecting the visual system, including the eyeball and related tissues. Common eye diseases include: central serous retinopathy, dry eye syndrome, sympathetic ophthalmia, night blindness, blindness, amblyopia, astigmatism, trachoma, cataracts, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, heterochromia iridis, retinitis pigmentosa, central retinal artery occlusion, retinal detachment, myopia, hyperopia, styes, snow blindness, chalazion, glaucoma, and floaters. During ophthalmic surgery, markings are made on the eyeball, and the surgery is performed at these marked locations. A marking ruler is a device used to mark these locations on the eyeball. For example, laser eye surgery requires centered on the pupil, proceeding radially along the surface of the eyeball at equal or regular intervals.

[0003] The current method mainly relies on the doctor's work experience to manually mark intervals along the radial direction. This method is affected by the doctor's work experience, resulting in inconsistent intervals between the marks, which is not conducive to doctors performing ophthalmic surgery. At the same time, it will directly increase the difficulty for novice doctors to get started, and has the disadvantages of low operation efficiency, high difficulty and inaccuracy.

[0024] Please see Figure 1 and Figure 2 In one or more embodiments, an eyeball marking ruler is provided, including a marking disk 100, a hand handle 101 is provided on the surface of the marking disk 100, and scale lines 102 are provided on the front of the marking disk 100. There are two scale lines 102, which are symmetrically arranged about the horizontal line of the marking disk 100. The marking disk 100 is spherical.

[0025] In this embodiment, the doctor grips the hand lever 101, moving the marking disk 100 to the patient's eyeball position. The smaller arc-shaped edge of the marking disk aligns with the edge of the patient's pupil to achieve a positioning effect. One of the scale lines 102 is used for marking. Then, the doctor grips the hand lever 101 again, moving the marking disk 100 to the patient's eyeball position, with the smaller arc-shaped edge aligning with the edge of the pupil for positioning. Another scale line 102 coincides with the marking point. At this point, the unused scale line 102 is used for marking. Repeating the above operation achieves the effect of precise interval marking of the patient's eyeball, thereby effectively reducing the difficulty of operation and learning for the doctor. The interval between the marking points is fixed and precise.

[0026] Please see Figure 1 and Figure 2 In some embodiments, the two sides of the marking disk 100 are arc-shaped, and the size of the arc-shaped side on the left is smaller than that of the arc-shaped side on the right. The top and bottom of the marking disk 100 are straight. The centers of the two arc-shaped sides are the same point, and the extensions of the two straight sides converge at a point. The convergence point of the extensions of the two straight sides is the same point as the centers of the two arc-shaped sides.

[0027] In this embodiment, the smaller arc edge will fit the edge of the patient's pupil, thereby enabling the marker ruler to achieve a positioning effect, ensuring that the center of the circle remains consistent when the position of the marker disk 100 is changed multiple times, thus achieving position fixation during the marking process; wherein, in order to adapt to different patients' eyeball sizes and different surgical marking requirements, the overall size, curvature, arc edge and straight edge length of the marker disk 100 can be adjusted according to the actual situation.

[0028] Please see Figure 1 As shown in the figure, in some embodiments, the surface of the handheld lever 101 is provided with anti-slip texture 103, and the marking disc 100 is made of either stainless steel or titanium alloy.

[0029] In this embodiment, the anti-slip texture 103 is provided to increase the friction when the doctor grips the rod, thereby reducing the probability of the marking ruler slipping off; the material of the marking disc 100 in this application includes, but is not limited to, the above-mentioned materials, and it should be made of materials that are harmless to the human body, corrosion-resistant, and do not easily cause allergic reactions.

[0030] Specifically, the working principle of the eyeball marking ruler provided in this application is as follows:

[0031] The doctor grips the hand lever 101 firmly, moving the marking disk 100 to the patient's eyeball position. The smaller, curved edge of the marking disk 100 is aligned with the edge of the patient's pupil to achieve a positioning effect. One of the scale lines 102 is used for marking. The doctor then grips the hand lever 101 firmly again, moving the marking disk 100 to the patient's eyeball position, with the smaller, curved edge aligned with the edge of the pupil for positioning. Another scale line 102 coincides with the marking point. At this point, the unused scale line 102 is used for marking. Repeating the above operation achieves the effect of precise interval marking of the patient's eyeball.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
