Prefabricated suture for fixing sclera plate layer of artificial lens
Technical Field
The invention relates to the field of suture medical supplies for ophthalmic surgery, in particular to a preformed suture for fixing an artificial lens sclera plate layer and an application and a using method thereof.
Background
Dislocation of the crystalline lens is a common complication of ocular trauma, and can also occur in normal people or in lens dislocation families (a familial genetic disease), which can cause vision loss, and the subsequent glaucoma can cause the eye blindness to be unable to compensate, and the like. The common surgical treatment for dislocation of the crystalline lens is fixation of the intraocular lens, i.e. the crystalline lens is taken out first and then a single intraocular lens is fixed on the wall of the eye. In this operation, the thread fixed by the suture will rub the eyeball and cause severe pain to the eyeball if the thread is left outside the eyeball, so the suture is embedded in the scleral layer, and the conventional method of the operation is very tedious, and though the improvement of many years, the thread is still one of the most complicated and most 'frightened' operations of the ophthalmology. The specific steps of the conventional surgery are as follows: 1. and (4) making a conjunctival flap, stopping bleeding, a scleral flap, taking out the dislocated crystalline lens, cutting the anterior vitreous body, and suturing an incision. 2. Nasal and temporal conjunctival scissors and conjunctival flaps are made. Stopping bleeding under conjunctiva. 3. The scleral flap on both sides was made separately. 4. The two flaps of the intraocular lens are tied and fixed by two 10-0 polypropylene sutures respectively, the intraocular lens and the sutures are implanted into the eyes, a needle head with the diameter of 1mm is used for penetrating into the eyes from the outside to the inside and a corresponding needle with the diameter of 10-0 mm is used for penetrating, a needle with the diameter of 1mm is used for leading out, and the intraocular lens is knotted and fixed under the scleral flap (one needle is fixed on each of the nasal side and the temporal side). Then, one to two needles of the scleral flap and two needles of the conjunctival flap are sutured respectively.
In order to solve the above-mentioned problems and simplify the above steps, it is necessary to invent a simple method for fixing an intraocular lens, which simplifies the procedure of the intraocular lens fixing operation, reduces the surgical complications, and improves the success rate of the operation.
