Abstract
The utility model discloses equipment used in one group of operation for glaucoma, comprise the electromagnetic coil of planting sheet and adjustable current intensity and frequency be made up of non-biological material and fixing magnetisable material support component in the inner.Use this utility model, both can reduce the adhesion of anti-glaucoma surgery scleral flap, and the effect of eyeball massage can have been played again after surgery, regulate postoperative intraocular pressure, operation long-term effect can be improved, reduce the mortality of trabeculectomy.
Description
Technical field
This utility model relates to the equipment of anti-postoperative scleral flap adhesion used in a kind of resisting glaucoma operation, belongs to area of medical devices.
Background technology
Glaucoma is the blinding oculopathy of a kind of irreversibility, and correct treatment can avoid the generation of blind.It is its main risk factor that intraocular pressure raises.For a long time, trabeculectomy is the topmost operation method of current clinical treatment glaucoma, and the object of operation is the intraocular pressure controlling patient.
In glaucoma filtration surgery, keep filtering the key that road unobstructed is successful surgery, and block the main cause that fistula road collar extension is operative failure.Traditional trabeculectomy treats the better modus operandi that glaucoma the most generally applies at present, but also exist and postoperatively have the tissue reaction of certain degree and synulotic shortcoming.Although at present in the modus operandi of Coffea arabiea and art, related drugs, equipment there has been very large development, in Post operation 2 years, mortality still reaches 15% ~ 30%.Failed main cause and postoperative filtration passage especially below scleral valve and between sclera and conjunctiva scar tissue hypertrophy relevant.
Anti-glaucoma surgery often needs patient to massage eyeball, ophthalmic aqueous humor being flowed out from filtering passage, both can regulate intraocular pressure, aqueous humor can be made again to wash away filtration passage, reduce cicatrization.But the many relevant ophthalmology knowledge of glaucoma patient, can not ensure the accurate of maneuver and dynamics when massaging, incorrect eyeball massage not only can not reach required effect, also may cause damage to eyeball.
Therefore, need one both can reduce postoperative scleral flap adhesion at anti-glaucoma surgery, the equipment of massage effect can be played again eyeball.
Utility model content
The utility model discloses equipment used in one group of operation for glaucoma, comprise the electromagnetic coil of planting sheet and adjustable current intensity and frequency be made up of non-biological material and fixing magnetisable material support component in the inner.Indwelling is in wall of eyeball below scleral valve in operation to plant sheet, and the accessory containing 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 in smooth arc, and be conduct magnetism metal, 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 comprising magnetisable material support component being positioned at below scleral valve, plant the pulse magnetic that sheet produces with electromagnetic coil and corresponding active force is produced to scleral flap, to prevent scleral flap adhesion.Plant sheet when magnetic force produces and have the trend be separated with sclera bed below it, be convenient to aqueous humor and discharge, thus regulate intraocular pressure by the interaction of planting between sheet and electromagnetic coil.
Use this utility model, both can reduce the adhesion of anti-glaucoma surgery scleral flap, and the effect of eyeball massage can have been played again after surgery, regulate postoperative intraocular pressure, operation long-term effect can be improved, reduce the mortality of trabeculectomy.

Detailed description of the invention
According to operating equipment of the present utility model, comprise an inside comprise magnetisable material, surface wrapped up by non-biological material plant sheet, in this partial surgical, indwelling is in wall of eyeball below scleral valve; And an accessory containing electromagnetic coil, this part is postoperatively to use outward at eyeball.The electromagnetism intensity that electromagnetic coil produces and frequency all can regulate according to intraocular pressure needed for patient.Normal intraocular tension scope is generally at 8-21mmHg, and the patient's intraocular pressure after operation for glaucoma often can higher than this scope.Equipment of the present utility model can be brought into use when postoperative patient intraocular pressure reaches more than 21mmHg or postoperative intraocular pressure raises rapidly.High current intensity and frequency can be selected when intraocular pressure overrun is more, to produce higher magnetic force, thus produce larger suction to planting sheet, intraocular pressure is reduced by a relatively large margin; Reduced-current intensity and frequency can be selected when intraocular pressure overrun is less, to produce lower magnetic force, thus produce less suction to planting sheet, intraocular pressure is reduced more by a small margin.Intraocular pressure is finally made to 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 to planting sheet and by the interaction of planting between sheet and electromagnetic coil, patient's intraocular pressure remained within the scope of 8-21mmHg.
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 fixed pattern or sequestered according to the actual requirements.Fixed pattern can be designed as plants sheet with suture hole, will plant sheet be fixed on the sclera bed of below during operation by suture; Sequestered then as shown in Figure 1-2, is directly paperwrapped in below scleral flap.Planting the magnetisable material held in sheet can be metal or Magnetitum thin slice, enough magnetic need be had, enough suction can be produced with extrabulbar electromagnetic coil accessory, to guarantee that planting sheet can produce enough active forces at scleral walls interlayer to the scleral flap above it when 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 play rejection with wall of eyeball tissue, and exterior material is enough thin, only plays the effect holding and separate 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 to produce good laminating with patient's eyelid in use, employing can the metal material of conduct magnetism, the magnetic force produced with effective conduct electricity magnetosphere, and all the other each several parts are inert material, conduction can not be produced, to avoid causing unnecessary interference to planting sheet during work to magnetic force.Position, sheet place is just planted to ophthalmic in electromagnetic coil position, can plant sheet produce enough captivations with ophthalmic.
