The invention discloses an instrument used during glaucoma surgery and discloses an instrument used during anti-glaucoma surgery and used for preventing post-operation sclera flap adhesion. The instrument used during anti-glaucoma surgery and used for preventing post-operation sclera flap adhesion comprises a corneal graft and an electromagnetic coil, wherein the corneal graft is composed of non-biological materials and a magnetic substance fixing component fixed into the non-biological materials, and the current intensity and the frequency of the electromagnetic coil can be adjusted. By the adoption of the instrument used during anti-glaucoma surgery and used for preventing post-operation sclera flap adhesion, the possibility of sclera flap adhesion occurring after the glaucoma surgery can be reduced, an eyeball can be massaged after the glaucoma surgery, the eye pressure is adjusted after the glaucoma surgery, the long-term effect of the surgery can be improved, and the failure rate of trabeculectomy is lowered.
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 passage 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 by non-biological material and fix the electromagnetic coil of planting sheet and adjustable current intensity and frequency that magnetisable material support component in the inner forms.Indwelling is in wall of eyeball below scleral valve in operation to plant sheet, and the accessory that contains electromagnetic coil uses outward at eyeball after surgery.
Electromagnetic coil is set to the pattern of adjustable current intensity and frequency, produces pulsed magnetic after energising.Its external structure one side is smooth arc, is conduct magnetism metal, and this metal covering can fit tightly with upper eyelid.The magnetic force that electromagnetic coil produces produces suction by the conduction of the metal covering in laminating upper eyelid to the sheet of planting that comprises magnetisable material support component that is positioned at below scleral valve, plant sheet, with the pulse magnetic of electromagnetic coil generation, scleral flap is produced to corresponding active force, to prevent scleral flap adhesion.When magnetic force produces, planting sheet has the trend separating with its below sclera bed, is convenient to aqueous humor and discharges, thereby regulate intraocular pressure by the interaction of planting between sheet and electromagnetic coil.
Use the present invention, both can reduce scleral flap adhesion after glaucoma operation, 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
Following accompanying drawing is schematic diagram, and its shape and ratio are only illustrative, are not construed as limiting the invention.

Fig. 4 is the front view of the outside appurtenances that contains electromagnetic coil, and wherein, 3 is electromagnetic coil, and 4 are and the metal covering of upper eyelid laminating.
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 frequency that electromagnetic coil produces all can regulate according to the required intraocular pressure of patient.Normal intraocular tension scope is generally at 8-21mmHg, and the patient's intraocular pressure after operation for glaucoma often can be higher than this scope.More than postoperative patient intraocular pressure reaches 21mmHg or when postoperative intraocular pressure raises rapidly, can bring into use equipment of the present invention.When intraocular pressure overrun is more, can select high current intensity and frequency, to produce higher magnetic force, thereby produce larger suction to planting sheet, intraocular pressure is reduced by a relatively large margin; When intraocular pressure overrun is less, can select reduced-current intensity and frequency, to produce lower magnetic force, thereby produce less suction to planting sheet, intraocular pressure is reduced more by a small margin.Finally make intraocular pressure remain in normal range.The electromagnetism intensity of electromagnetic coil and frequency can be regulated by external controller (not shown), concrete electromagnetism intensity scope and frequency range are determined according to concrete electromagnetic coil, and condition is that it produces suction and can patient's intraocular pressure be remained within the scope of 8-21mmHg by the interaction of planting between sheet and electromagnetic coil planting sheet.
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.Plant sheet and can be designed to according to the actual requirements fixed pattern or sequestered.Fixed pattern can be designed as plants sheet with suture hole, will plant sheet be fixed on the sclera bed of below when operation by suture; Sequestered as shown in Figure 1-2, is directly paperwrapped in scleral flap below.Planting the magnetisable material holding in sheet can be metal or Magnetitum thin slice, need there is enough magnetic, can produce enough suction with extrabulbar electromagnetic coil accessory, to guarantee that planting sheet can produce enough active forces to the scleral flap above it at scleral walls interlayer in the time that the electromagnetic coil in outside appurtenances produces magnetic force.The material requirements of planting sheet outside is inert substance, does not stick together, can not rise rejection with wall of eyeball tissue, 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 frequency, its external structure is designed to keep good laminating with upper eyelid, curved before it, to ensure can to produce good laminating with patient's eyelid in use, employing can conduct magnetism metal material, the magnetic force producing with effective conduct electricity magnetosphere, all the other each several parts are inert material, can not produce conduction to magnetic force, cause unnecessary interference to planting sheet when avoiding work.Position, sheet place is just planted to ophthalmic in electromagnetic coil position, can plant sheet with ophthalmic and produce enough captivations.
