Abstract
The invention relates to an artificial intraocular lens capsular sac adopting loop filaments for intraocular fixing, which comprises a capsular sac part and loop filaments for fixing. The capsular sac part is a transparent sac consisting of a front capsular membrane and a rear capsular membrane. The center of the front capsular membrane is provided with a hole. Small holes are also distributed on the front capsular membrane. More than one loop filaments for fixing are distributed in a central symmetry manner. Body parts of the loop filaments are provided with expanded parts. The artificial intraocular lens capsular sac can be used for treating aphakia without the intraocular lens capsular sac.
Description
Technical field
The present invention relates to a kind of artificial intraocular lenses's capsule bag, specifically, relate to and a kind ofly make the fixed artificial intraocular lenses's capsule of ophthalmic bag with button loop silk.
Background technology
Cataract is common oculopathy, and the form fix that in the cataract therapy process, need the artificial intraocular lenses be supported through button loop is in the capsule bag of natural lens.Pathological changes, wound or postoperative complication possibly cause lenticular capsule bag or fixedly the Suspensory ligament of capsule bag is impaired, thereby the artificial intraocular lenses can not be implanted in the lens capsule bag.
At present when lens capsule bag or Suspensory ligament are impaired can't carry out that the artificial intraocular lenses implants in the capsule bag time, fixedly the artificial intraocular lenses mainly contains several kinds of modes: method of clamping and suture fixed form:
Method of clamping is the different aspects that the artificial intraocular lenses are attached to tissue, holds such as iris clamping artificial intraocular lenses or artificial intraocular lenses's capsule sackholder, and it is slightly difficult that this mode is operated the supporting way of fastening with a rope, string, etc., and needs specific tissue and exist and can accomplish.If, then can't carry out when lens capsule bag or Suspensory ligament damage when serious.
The suture fixed form is will suture be passed the tissue back through toe-in artificial graft's thing to be fixed; This mode requires low to the integrity of tissue; But enclosed space within the eye knotting is unusual difficulty, and the operation technique difficulty is big, operating time be the button loop supporting way ten surplus times.
Summary of the invention
The technical problem that will solve of the present invention provides a kind of artificial intraocular lenses's capsule bag; It penetrates scleral walls through the fixed mode of button loop silk; With the elasticity of button loop silk and the part of expanding artificial intraocular lenses's capsule bag is fixed on the scleral walls, thereby has avoided fixing this type complicated operation operation of suture.
For solving the problems of the technologies described above, artificial intraocular lenses's capsule bag of the present invention comprises capsule bag part and the fixing button loop silk of using, wherein:
Said capsule bag is the transparent bag for being made up of anterior capsule and back cyst membrane partly, and anterior capsule central authorities are porose, and on anterior capsule, also are distributed with aperture;
The said number of fixedly using button loop silk is greater than 1 and for centrosymmetry distributes, and in the filament portion that fastens with a rope, string, etc. the part of expanding arranged.
Preferably, the outer circumference diameter of said capsule bag part is 8-12mm, and cyst membrane thickness is 0.2-0.6mm, and the aperture of anterior capsule medium pore is 4-6mm.
The current of buying a house in installments that act as of said anterior capsule aperture lead to, and preferred, the number of said aperture is 1-3, and diameter is 0.2-0.25mm.
Preferably, be distributed with number on the cyst membrane of said back greater than 1 and be the circular-arc projection of centrosymmetry distribution, it is placed in the middle to be used to limit intraocular lens optic portion.Preferred, the formed interior diameter of circular-arc projection that said centrosymmetry distributes is 5.5-7mm.
Preferably, be distributed with aperture on the cyst membrane of said back, and the position of the aperture on the position of this aperture and size and the above-mentioned anterior capsule and big or small corresponding.
Preferably, cyst membrane central authorities in said back have diameter to be not more than the hole of 6mm, are used to keep avoid forming dead space with extraneous the communication in the hyaline membrane.
Preferably, the number of said fixedly use button loop silk is 3 or 4, and length is 5-7mm, and thickness is 0.3-0.5mm, and width is 0.4-0.6mm, and the top of said button loop silk is anti-slip T shape, zigzag, barb-like structure.
Saidly expand acting as of part and be stuck in the sclerotic puncture mouth and sentence and reach the fixed purpose of ophthalmic; Preferably; Said number of expanding part is 1-3, when expanding the number of part during greater than 1, can select a place to expand part according to the size of eyeball and fix.
Preferably, on said anterior capsule, also further be distributed with the crack, operating theater instruments is conveniently used in acting as of this crack.More preferably, the number in said crack is 1-3, and length is 1.5-2.5mm.
Preferably, above-mentioned capsule bag part uses the button loop silk by any identical or different biocompatible materials with fixing, and includes but not limited to silica gel, polyethylene, PMMA (polymethyl methacrylate), acrylic ester etc.
Preferably, above-mentioned capsule bag part is one-body molded through casting film with the fixing button loop silk of using, and waits reworking thereby need not polish punching, after cleaning, encapsulation, sterilization, can supply clinical use.
Artificial intraocular lenses's capsule bag of the present invention can be used for treating the human eye of cataract with lens capsule bag or Suspensory ligament pathological changes or aphakia, plays the effect of crystal capsule bag.
When artificial intraocular lenses's capsule bag of the present invention is implanted in operation; Earlier artificial intraocular lenses's capsule bag is curled after implantation device is implanted the anterior chamber, treat that it launches naturally after, will fasten with a rope, string, etc. with entry needle through the sclerotic puncture mouth thread is directed to outside the sclera; Because button loop wire material elastical retraction; Select a place to expand part according to the needs of eyeball size and be stuck in sclerotic puncture mouth place, prunes unnecessary button loop thread then in the sclera flaggy, bury fixing, do not need extra sunken cord fixing.
Carrying out follow-up artificial intraocular lenses when implanting, can be with the direct implantable artificial crystal of artificial intraocular lenses capsule bag, the button loop horizontal positioned also can partly be stuck in intraocular lens optic between the circular-arc projection of artificial intraocular lenses's capsule bag.
