Abstract
The utility model relates to an intraocular lens suitable for ligamentopexis between wicresoft sclera layer, includes intraocular lens optics portion, connect about intraocular lens optics portion both ends, be 2 intraocular lens buttons loop of " C " style of calligraphy, its characterized in that intraocular lens button loop trailing end connection has the pull wire, and the trailing end connection of pull wire pulls the needle.
Description
Technical field
This utility model relates to field of medical technology, particularly a kind of artificial intraocular lenses being applicable to fixation between Wicresoft's Scleral shell.
Background technology
In normal cataract procedure, in the lenticular pouch of Intraocular implantation, but for the Intraocular implantation supported without cyst membrane, as in cataract procedure, cyst membrane breaks accidentally, or the cyst membrane that causes of the reason such as wound is imperfect when can not support artificial intraocular lenses, people generally adopt artificial intraocular lenses's suspension, namely the two button loop nonabsorable lines of artificial intraocular lenses are fixed in scleral walls, in ciliary groove.This operation method is because needing in art tied a knot with nonabsorable prolene suture and be fixedly sutured in scleral walls by artificial intraocular lenses's two buttons loop, operation technique is wasted time and energy and because of the too thin operating difficulties of suture, and the postoperative toe-in that also has exposes and causes that patient is uncomfortable, endophthalmitis equivalent risk even occurs foreign body sensation.Recent research also finds, toe-in has the danger of generation fracture within the eye for more than 10 years and causes Dislocated IOL, again need perform the operation, increase the weight of sufferer misery.For addressing this problem, we design a kind of artificial intraocular lenses, in art without the need to crystal two fasten with a rope, string, etc. suture knotting, two buttons loop of this artificial intraocular lenses can also be fixed between Scleral shell easily, and otch is little, wound is little, and position of intraocular lens is satisfied, and postoperative artificial intraocular lenses is not easily shifted, reduce toe-in to stimulate, reduce endophthalmitis probability of happening, postoperative patient vision restoration is fast, and can increase the postoperative comfort of patient etc.
Utility model content
This utility model is in order to solve the problem, and providing a kind of does not need the two button loop knotter work crystal of prolene suture artificial intraocular lenses.
A kind of artificial intraocular lenses being applicable to fixation between Wicresoft's Scleral shell, comprise intraocular lens optic portion, be connected to two ends, left and right, intraocular lens optic portion, 2 artificial intraocular lensess button loop in " C " font, it is characterized in that described artificial intraocular lenses tail end of fastening with a rope, string, etc. is connected with draught line, the tail end of draught line is connected with pull needle.
Further, described artificial intraocular lenses's button loop is in " C " font.
Further, described draught line is connected directly between artificial intraocular lenses and fastens with a rope, string, etc. tail end.
Further, intraocular lens optic portion is limpid, flexible folding acrylic acid.
Further, artificial intraocular lenses two fastens with a rope, string, etc. as blue core polymethyl methacrylate materials, band flour milling.
Further, draught line is polypropylene material, and diameter is 10-0 line, and line length is 2cm.
Further, pull needle is rigid material, solid, and diameter is 0.16mm, the long 5mm of pin.
Accompanying drawing explanation
Fig. 1 is this utility model schematic diagram.
Detailed description of the invention
With reference to figure 1, wherein fasten with a rope, string, etc. 1b and artificial intraocular lenses of about 1a two ends, intraocular lens optic portion compact siro spinning technology artificial intraocular lenses fastens with a rope, string, etc. 2b, and fasten with a rope, string, etc. 1b and artificial intraocular lenses of artificial intraocular lenses fastens with a rope, string, etc. 2b in " C " font, and end is compact siro spinning technology draught line 1c and draught line 2c respectively; Draught line 1c and draught line 2c tail end compact siro spinning technology pull needle 1d and pull needle 2d respectively.
Intraocular lens optic portion 1a is limpid, flexible folding acrylic acid, with chemical covalent bonds in conjunction with UV absorbent.Its refractive power-10.0 is to+30.0D, and increment is 0.5D.
Artificial intraocular lenses 1b and the artificial intraocular lenses 2b that fastens with a rope, string, etc. that fastens with a rope, string, etc. is blue core polymethyl methacrylate materials, slightly elasticity, band flour milling.When fasten with a rope, string, etc. 1b and artificial intraocular lenses of artificial intraocular lenses fastens with a rope, string, etc. when 2b is fixed between Scleral shell and increase frictional force, artificial intraocular lenses is not easily dislocated.Draught line 1c and draught line 2c is polypropylene material, 10-0 line, each 2cm in line length two ends, nonabsorable, in art until artificial intraocular lenses fasten with a rope, string, etc. 1b and artificial intraocular lenses fasten with a rope, string, etc. 2b pull out sclera outer after, this draught line 1c and draught line 2c can wipe out completely.
Pull needle 1d and pull needle 2d is rigid material, solid 30G, slightly about 0.16mm, reduces the wound to wall of eyeball in art, and belong to Minimally Invasive Surgery, long 5mm, with draught line 1c and draught line 2c compact siro spinning technology.In art until artificial intraocular lenses fasten with a rope, string, etc. 1b and artificial intraocular lenses fasten with a rope, string, etc. 2b pull out sclera outer after, this pull needle 1d and pull needle 2d can wipe out completely together with draught line 1c and draught line 2c.
Perform the operation for patient's right eye:
Patient's right eye routine disinfection drape, after local anaesthesia is satisfied, right eye puts eye speculum, conjunctival sac povidone iodine cotton balls wiping twice, normal saline flushing.
Do along limbus of corneae 3 and 9 places the conjunctival flap that 4*5mm take fornix as substrate, electric coagulation hemostasis, does the Lamellar scleral flap that 3*4mm take limbus of corneae as substrate at 3 o'clock to 9 o'clock respectively under conjunctival flap.
3.0mm transparency cornea edge otch is done in 12, top, anterior chamber injects viscoelastic agent, 9 place's below scleral valves, 2mm place is about apart from limbus of corneae, penetrate 27G drag spring thimble to ophthalmic pupillary margin place, pull needle 1d through pupillary margin, fills in 27G drag spring thimble through 12 cut-out of limbus corneae by described a kind of pull needle 1d being applicable between Scleral shell fixing artificial intraocular lenses, extract 27G drag spring thimble, take advantage of a situation and take pull needle 1d, draught line 1c and artificial intraocular lenses out of and fasten with a rope, string, etc. outside 1b to 9 place's sclera.Intraocular lens optic portion 1a is folded, and fills in ophthalmic from limbus of corneae 12.Fasten with a rope, string, etc. 1b to outside sclera from 3 pull needle 1d, draught line 1c taking the other end out of and artificial intraocular lenses with above-mentioned same method.So far 2 artificial intraocular lensess 1b that fastens with a rope, string, etc. takes out of respectively to outer 9 points of sclera, 3 places.Wipe out draught line 1c completely, and pull needle 1d.
9 place below scleral valve 27G drag spring thimbles are most advanced and sophisticated does scleral tunnel along crystal 2 directions of fastening with a rope, string, etc., and takes advantage of a situation and fills in scleral tunnel by button loop 2, and the same method 1b that the artificial intraocular lenses of the other end fastened with a rope, string, etc. fills in 3 place's scleral tunnels.Adjust 2 artificial intraocular lensess and fasten with a rope, string, etc. the position of 1b and 1a position, intraocular lens optic portion to satisfied, sew up scleral incision and conjunctival incision.Operation completes.
