[0048] In some embodiments, the high myopia posterior sclera reinforcement component further includes a reinforcing member 500. The reinforcing member 500 is connected to the support pad 100 to enhance the strength of the support pad 100.
[0049] In some embodiments, the reinforcement member 500 is a titanium sheet.
[0050] In some of the embodiments, a plurality of positioning holes 101 are provided on the third support bar 400 , and the reinforcement member 500 is connected to the support pad 100 through the positioning holes 101 .
[0051] In some of the embodiments, the edge of the support pad 100 has a chamfered design, so that after the scleral reinforcement component for high myopia is implanted in the human eye, the optic nerve will not be damaged even if the reinforcement member 500 such as a titanium sheet moves.
[0052] The position of the reinforcing member 500 in the support pad 100 has been improved, and the edge of the reinforcing member 500 is completely retracted in the support pad 100, that is, the edge of the reinforcing member 500 does not protrude from the edge of the support pad 100, so that the reinforcing member 500, such as a titanium sheet, can be prevented from protruding and cutting the optic nerve. In addition, the reinforcing member 500 can increase the top pressure of the product, so that the cracked part can be effectively improved or reset.
[0053] In some embodiments, the surface of the support pad 100 is an inwardly concave structure, and the surface of the inwardly concave structure of the support pad 100 is rounded. The inwardly concave structure of the support pad 100 can be designed by finely simulating the eye axis and eyeball with a computer.
[0054] In some of the embodiments, the thickness of the support pad 100 is 1.0-4.0 mm. Such a design makes the posterior scleral reinforcement component of high myopia thinner and lighter as a whole, which can reduce the patient's foreign body sensation during use and increase comfort. For example, in one specific example, the thickness of the support pad 100 is 1.0 mm, and in another specific example, the thickness of the support pad 100 is 4.0 mm. It is not difficult to understand that in other examples, the thickness of the support pad 100 can also be 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or other parameters.
[0055] In some embodiments, the surface of the first support bar 200 has a plurality of first grooves 201 that contact the eyeball to prevent the posterior scleral reinforcement component of high myopia from sliding in the eye. Preferably, the edge of the first groove 201 has a chamfer. The first groove 201 facilitates ligation and fixation of the posterior scleral reinforcement component of high myopia, avoiding the risk of the posterior scleral reinforcement component of high myopia falling off, and at the same time, the first groove 201 with a chamfer produces less foreign body sensation when it contacts the eye, which is safer.
[0056] In some embodiments, the surface of the second support bar 300 has a plurality of second grooves 301 that contact the eyeball to prevent the posterior scleral reinforcement component of high myopia from sliding in the eye. Preferably, the edge of the second groove 301 has a chamfer. The second groove 301 facilitates ligation and fixation of the posterior scleral reinforcement component of high myopia, avoiding the risk of the posterior scleral reinforcement component of high myopia falling off, and the chamfered second groove 301 produces less foreign body sensation when in contact with the eye, which is safer.
[0057] In some embodiments, the surface of the third support bar 400 has a plurality of third grooves 401 that contact the eyeball to prevent the posterior scleral reinforcement component for high myopia from sliding in the eye. Preferably, the edge of the third groove 401 has a chamfer. The third groove 401 facilitates ligation and fixation of the posterior scleral reinforcement component for high myopia, avoiding the risk of the posterior scleral reinforcement component for high myopia falling off, and the chamfered third groove 401 produces less foreign body sensation when in contact with the eye, which is safer.
[0058] In some of the embodiments, the angle between the first support bar 200 and the second support bar 300 is 120°-185°. For example, in one of the embodiments, the angle between adjacent first support bars 200 and second support bars 300 is 120°. In another embodiment, the angle between adjacent first support bars 200 and second support bars 300 is 185°. Preferably, in one of the embodiments, the angle between adjacent first support bars 200 and second support bars 300 is 170°.
[0059] In some embodiments, the support pad 100 is provided with elliptical through holes 102. The elliptical through holes 102 allow blood vessels to grow through these holes.
[0060] In some embodiments, the support pad 100 is provided with a central hole 103. The central hole 103 allows blood vessels to grow through the holes.
[0061] In some embodiments, the support pad 100 is provided with a plurality of surrounding holes 104 surrounding the central hole 103. The surrounding holes 104 allow blood vessels to grow through the holes.
[0062] In some embodiments, the edge of the support pad 100 is provided with a clearance portion 105, which can avoid damaging the optic nerve. The clearance portion 105 can be arranged between the first support bar 200 and the second support bar 300 and opposite to the third support bar 400.
[0063] When the above-mentioned high myopia posterior sclera reinforcement component is in use, the support pad 100 is implanted into the sclera corresponding to the macula of the eyeball, and the third support bar 400 can adjust the curvature according to the condition of the eyeball. The smooth structure at the end of the first support bar 200 and the second support bar 300 can facilitate the doctor to quickly pass the first support bar 200 and the second support bar 300 through the lateral rectus muscle, inferior rectus muscle and inferior oblique muscle.
[0064] Compared with the conventional posterior sclera reinforcement device, the above-mentioned high myopia posterior sclera reinforcement component has the following beneficial effects:
[0065] (1) The first support bar 200, the second support bar 300 and the end of the second support bar 300 of the above-mentioned high myopia posterior sclera reinforcement component are rounded, thereby avoiding the risk of damaging the eyeball and reducing the patient's foreign body sensation.
[0066] (2) The support pad 100 of the posterior scleral reinforcement component for high myopia is designed into a sunken structure that can wrap the eye axis and eyeball through computer precise simulation of the eye axis and eyeball, which can better fit the eye axis and eyeball and achieve better pressure effect.
[0067] (3) The first support bar 200, the second support bar 300 and the second support bar 300 of the above-mentioned high myopia posterior scleral reinforcement component are designed with clear scales, which can allow medical staff to better judge the implantation position during surgery.
[0068] (4) The first support bar 200, the second support bar 300 and the third support bar 300 of the above-mentioned high myopia posterior sclera reinforcement component are all provided with corresponding chamfered grooves, such as the first groove 201, the second groove 301 and the third groove 401, which can prevent the high myopia posterior sclera reinforcement component from sliding in the eye, making it safer.
[0069] (5) The elliptical through holes 102 on the support pad 100 of the posterior scleral reinforcement component for severe myopia can allow blood vessels to grow better.
[0070] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
