The present invention relates to medical science, more specifically relate to be used in the ophthalmology curing the cataractous artificial lenses that causes by any cause of disease.
Known a kind of artificial lenses, comprise arc-shaped support component (for example two circle holes) (ophthalmology, nineteen eighty-two, the 89th volume, N8, S128 that opticator (crystalline lens) and radial symmetric are provided with, the pC-60 type), the arm end of support component is fixed on the opticator.
During use, the structural requirement of this artificial lenses has fine inflexible support component, so that it can be fixed in the patient's eyes exactly, and can keep oneself position in the eye district of regulation, can not move and be out of shape.
But this support component elasticity is relatively poor, and their size can not have great variation when doing implant surgery, thereby operation is had any problem, and makes the time lengthening of operation.In addition, inflexible support component can cause the serious loss of cell of iris pigment sheet and posterior epithelium of cornea,epithelium posterius cornea when operation, and develops into the postoperative complication as insecondary glaucoma and chronic iridocyclitis and so on afterwards; The implant surgery apparatus that the requirement of the artificial lenses of major diameter size is special has prolonged the time of operation too; Also must make multiple size with the corresponding prosthetic lens of capsulociliary diameter.
Task of the present invention provides a kind of prosthetic lens, the structure of this lenticular support component makes can dwindle these size of component when carrying out implant surgery, can also keep simultaneously artificial lenses accurately is fixed on the desired rigidity in precalculated position in the patient's eyes, thereby the implant surgery time is shortened and reduce operation wound.
The measure that solves task of the present invention provides a kind of synthetical crystalline lens, comprise the arc-shaped support component that opticator and radial symmetric are provided with, the arm end of support component is fixed on the opticator, according to the present invention, there is linkage section at the middle part of each arch-shaped elements, the support component arm is connected with each other, and they can be rotated in the plane of arc-shaped support component relatively.
According to one embodiment of the present of invention, the linkage section that the support component arm is connected with each other is made the spiral circle that is positioned at the opticator next door.
Essence of the present invention is artificial lenses, comprising: opticator; Two symmetric arc-shaped support components that radially are provided with respect to opticator, each support component is made of the arm that is fixed on the described opticator; There is linkage section at the middle part of each arc-shaped support component, and holding arms couples together, and they can be rotated in the plane of arc-shaped support component relatively.
According to an alternative embodiment of the invention, the linkage section that the support component arm is connected with each other is made at least one recess that is arranged on the support component outside.
Best, on the outside of described spiral turns, have a recess at least.
There are spiral circle or at least one recess can reduce the rigidity of support component at the middle part of support component, and when carrying out implant surgery and clamp it with tweezers, the middle part of support component can be moved toward the opticator of artificial lenses, thereby the arm move toward one another of support component, the arm of every support component rotates with respect to its stiff end in the plane of support component.The displacement of support component arm is dwindled the size of support component, and the support component size amount of dwindling depends on the specific tasks of operation and the characteristics of the eyes that will have an operation.
Except above-mentioned advantage, the embodiment of the linkage section of described support component arm also has following advantage: can clamp support component with tweezers easily when implanting crystalline lens, and make the surgical operation that support component is put into phacocyst or ciliary groove become simple, when implanting crystalline lens, can not damage phacocyst, and reduce the wound of iris pigment sheet and posterior epithelium of cornea,epithelium posterius cornea cell.Use the present invention can reduce the off-centre as the relative eyes optical axis of prosthetic lens, the postoperative complication of insecondary glaucoma and iridocyclitis and so on.
Further specify the present invention below by embodiment and accompanying drawing, in the accompanying drawing:
Fig. 1 shows total figure of artificial lenses of the present invention;
Fig. 2 is identical with Fig. 1, but represents with side view;
Fig. 3 shows the linkage section that the support component arm is coupled together;
Fig. 4 shows another embodiment of the linkage section that the support component arm is coupled together;
Fig. 5 shows another embodiment of the linkage section that the support component arm is coupled together.
Artificial lenses comprises opticator 1(Fig. 1) and two arc-shaped support components 2 that radial symmetric is provided with, the arm end 3 of the arm 4 of support component 2 can be fixed on the opticator with any known method.The linkage section 5 that the middle part handlebar support component arm 4 of each arc-shaped support component 2 is connected with each other can rotate them relatively in the plane of arc-shaped support component.
According to Fig. 1,2 and 3, the linkage section 5 that the support component arm couples together is made the next door that a spiral circle 6 is positioned at opticator 1, perhaps be formed in as shown in Figure 4 have a recess 7(Fig. 4 on support component 2 outsides at least).
Corresponding to Fig. 5, holding arms couples together and the linkage section 5 of making spiral coil 6 forms has recess 8 in the outside of circle, and the quantity of recess can be one, two, three, as shown in Figure 5.
Prosthetic lens can be implanted in the following method.
Partly cutting cornea corresponding to the hour hands arrow locations between 11 and 13 in the dial plate, amplify pupil with 1% methadone (Me3atoH) solution-wet anterior chamber, capsule is extractd the nuclear and the lenticular material of finding time then before opening.The adjustable tweezers of reuse (Binkhorst) are clamped prosthetic lens and with cutting capsule hook (Γ Λ а ū ɡ) lower support element are put into down in the vault of capsule.
Then tweezers and a section capsule hook are shifted out from the eye chamber.
Clamp lower part (Fig. 1 of circle 6 with tweezers, 3,5) or recess 7(Fig. 4) central segment of upper support element 2 is moved (Fig. 1) towards the direction of opticator 1, at this moment, two arms of support component 2 move in opposite directions, and their stiff ends 3 with respect to arm in the plane of support component 2 rotate.Thereby the size of support component 2 is dwindled, simultaneously, make at linkage section 5 under the situation of circle 6, thereby the diameter that makes circle during owing to the arm move toward one another increases the support component size is dwindled, also the deflection owing to the support component arm is dwindled the size of support component, and makes at linkage section 5 under the situation of form of recess 7 just owing to arm dwindles the size of support component to the direction deflection of opticator.
Then, film back on the preceding capsule is inserted on support component top.Again preceding capsule is sealed and with isotonic saline solution its drastic reduction to 3.0mm finish the operation.
Because support component has the elasticity that the surface that can guarantee lens is adapted to surrounding tissue well, in implantable phacocyst of prosthetic lens and the ciliary groove.
Because when implanting prosthetic lens of the present invention, reduced the probability of operation and postoperative complication and patient's medical science and professional restored cycle are shortened.Like this, adopt prosthetic lens of the present invention can shorten the implant surgery time 25～30%.This is because the structure of this prosthetic lens guarantees that the operation that it is implanted in the phacocyst is simple, has reduced the surgery operating wound rate.Support component has the stability of enough rigidity and prosthetic lens position in phacocyst, and implant surgery simply makes and reduces when implanting or in postoperative ocular tissue wound, also reduced the damage of iris pigment sheet and the loss of cuticle theca cell.
