Abstract
The invention discloses a group of device for glaucoma operation, and provides a postoperative sclera flap adhesion preventive device for anti-glaucoma operation. The postoperative sclera flap adhesion preventive device comprises an abiological material, a graft and an accessory. The graft is cast in the abiological material and comprises a magnetic substance support component, and the accessory comprises an electromagnetic coil with adjustable current intensity and rhythm. The postoperative sclera flap adhesion preventive device has the advantages that glaucomatous postoperative sclera flap adhesion can be reduced by the aid of the postoperative sclera flap adhesion preventive device, an eyeball massaging effect can be realized after the operation, the intraocular pressure of a patient can be regulated after the operation, a long-term effect of the operation can be improved, and a failure rate of trabeculectomy can be reduced.
Description
Technical field
The equipment that the present invention relates to anti-postoperative scleral flap adhesion used in a kind of resisting glaucoma operation, belongs to area of medical devices.
Background technology
Glaucoma is a kind of irreversibility blinding oculopathy, and correct treatment can be avoided the generation of blind.It is its main risk factor that intraocular pressure raises.For a long time, trabeculectomy is to treat clinically at present the topmost operation method of glaucoma, and the object of operation is to control patient's intraocular pressure.
In glaucoma filtration surgery, keeping filtering the unobstructed of road is the key of successful surgery, is the main cause of operative failure and block fistula road collar extension.Traditional trabeculectomy is to treat at present the better modus operandi that glaucoma is the most generally applied, but also has postoperative tissue reaction and the synulotic shortcoming that has certain degree.Although related drugs, equipment have had very large development in the modus operandi of at present trabecular resection operation and art, the mortality in latter 2 years of performing the operation still reaches 15%～30%.Between failed main cause and postoperative filtration passage especially below scleral valve and sclera and conjunctiva, scar tissue hypertrophy is relevant.
After glaucoma operation, often need patient to massage eyeball, ophthalmic aqueous humor is flowed out from filtering passage, both can regulate intraocular pressure, can make again aqueous humor wash away filtering passage, reduce cicatrization.But the how relevant ophthalmology knowledge of glaucoma patient can not ensure the accurate of maneuver and dynamics in the time of massage, and incorrect eyeball massage not only can not reach required effect, also may cause damage to eyeball.
Therefore, need one can after glaucoma operation, both can reduce postoperative scleral flap adhesion, can play to eyeball again the equipment of massage effect.
Summary of the invention
The invention discloses equipment used in one group of operation for glaucoma, comprise the accessory of the electromagnetic coil of planting sheet and containing adjustable current intensity and the rhythm and pace of moving things being formed by non-biological material and casting magnetisable material support component in the inner.
Use the present invention, both can reduce the adhesion of green light Zhang Shuhou scleral flap, can play after surgery again the effect of eyeball massage, regulate postoperative intraocular pressure, can improve operation long-term effect, reduce the mortality of trabeculectomy.
Brief description of the drawings
Fig. 1 is for planting sheet front view, wherein, 1 non-biological material holding for outside, 2 is internal magnetization material, planting sheet is in rectangle or ladder diagram, to be rectangle), length and width require to be less than 4mm × 3mm.
Fig. 2 plants sheet side view, wherein, 1 non-biological material holding for outside, 2 is internal magnetization material, thickness requirement is less than 0.5mm.
Detailed description of the invention
According to operating equipment of the present invention, what comprise that an inside comprises that magnetisable material, surface wrap up by non-biological material plants sheet, and in this part operation, indwelling is in wall of eyeball below scleral valve; And an accessory that contains electromagnetic coil, this part is postoperatively to use outward at eyeball.Electromagnetism intensity and the rhythm and pace of moving things that electromagnetic coil produces all can regulate according to the required intraocular pressure of patient.
The described sheet of planting is rectangle or trapezoidal, and its length and width are less than 4mm × 3mm, and thickness is less than 0.5mm.Planting that sheet can be designed to according to the actual requirements can fixed pattern or sequestered, and planting the magnetisable material holding in sheet can be metal or Magnetitum thin slice, need have enough magnetic, can produce enough suction with extrabulbar electromagnetic coil accessory; The material requirements of planting sheet outside is inert substance, does not entangle to knit with wall of eyeball to stick together, can not rise rejection, and exterior material is enough thin, only plays and holds the effect of separating internal magnetization material, and can not affect the magnetic of inner material.
The major part of outside appurtenances is an electromagnetic coil that can regulate electromagnetism intensity and the rhythm and pace of moving things, its external structure can design according to actual needs, requirement can keep good laminating with upper eyelid, position, sheet place is just planted to ophthalmic in electromagnetic coil position, can plant sheet with ophthalmic and produce enough captivations.
Claims (7)
1. equipment used in one group of operation for glaucoma, it comprises plants sheet and the accessory that contains electromagnetic coil, described in plant sheet and formed by non-biological material and casting magnetisable material support component in the inner, the contained electromagnetic coil of described accessory can regulate current intensity and the rhythm and pace of moving things.
2. according to the equipment of claim 1, the wherein said sheet of planting is rectangle or trapezoidal.
3. according to the equipment of claim 2, wherein said length and width of planting sheet are less than 4mm × 3mm, and thickness is less than 0.5mm.
