Description
The present invention relates to a kind of operating on because of cataract and the crystal of eyeball is taken out the back substitute the intraocular lens insertion of being used when this crystal inserts ophthalmic with deformable lens and use utensil, particularly the insertion tube of retaining member is through the deformable apparatus for inserting lens into eyes of improvement.
When generally making the excising operation of cataract eyeglass, (in-cision) is littler for the otch that cuts on the eyeball, and it is littler that scattered-light probability takes place in the operation back.
For this reason, be developed out a kind of so-called ultrasonic crystal emulsifying suction (KPE) of using ultrasound emulsifying suction device.Skill is to utilize above-mentioned ultrasound emulsifying suction device according to this, the crystal of nebulousurineization is smashed and emulsifying after with its sucking-off.So only can be with lens extraction to the otch of the about 4mm of eyeball incision.This compares with the traditional ECCE (ECCE) that need cut the otch of about 10mm when the extracting lens, and is obviously progressive.
For cooperating above-mentioned little cutting operation method, the intraocular lens that existing a kind of at present otch from childhood inserts ophthalmic is developed.Traditional intraocular lens is to have the optic of being made by hard materials such as glass or plastic cement (optical part), and the otch size when therefore transplanting must be greater than the diameter of this optic.Multiple occasion, the otch size is at 6.5mm or bigger.Because this kind relation, even if, when inserting the intraocular lens of hard, otch need be cut expansion once again according to the KPE otch extracting lens from childhood of performing the operation.
In the clear 58-18005 of Japanese Patent Application, have and disclose a kind of deformable eyes buitin lens that can insert from the little otch of eyeball.These lens 1 are the optic 2 that form of the deformable elastomer by the memory characteristic fixed to have and the support sector 3 that 2 of this optic are held in ophthalmic are constituted as shown in Figure 6.Support sector 3 and optic 2 are to form with different types of pliability material, base portion 3a are imbedded the peripheral part of optic 2 and are fixed, with first end 3b bending and the 3 symmetric configurations of two support sectors.Another kind is as shown in Figure 7, has the optic 2 identical with optic shown in Figure 6, and in the outwards outstanding laminar support sector 4 of the formation of the periphery subtend of this optic 2 and one to support the structure of optic 2.
As for deformable apparatus for inserting lens into eyes, then have for example to be disclosed in the flat 3-14206 person of Japanese Patent Application.This inserts utensil, as shown in Figure 8, have: leading section is provided with the roughly tubular apparatus body 5 of the formerly distolateral assembling ditch 5a in its narrow wide position, by the release axle 6 that is intercalated in vessel 5 and for making these push-off pin 6 advance and retreat be screwed into the ejecting mechanism 8 that the cylindrical shell 7 in the apparatus body constitutes, reach and insert the distolateral retaining member 12 of elder generation that tube (insertion mouth) 11 protrudes in the lens maintaining part 10 that has switching mechanism 9.
Said lens maintaining part 10 lies in being provided with of rear end one of inserting tube 11 and fixes half 13, simultaneously subtend is set freely in fixing half 13 movable half 14 in opening and closing near the rear end of inserting tube 11, borrow hinge to link and fix half 13 and movable half 14 lower edge, but and in fixing half 13 and movable half 14 prominent upward respectively fixation clip 15 and the dynamic pressure plate 16 established of upper limb.
In addition, but constitute switching mechanism by movable half 14, hinge and dynamic pressure plate 16.When closing this switching mechanism 9, movable half 14 is touched and fixes half 13 but dynamic pressure plate 16 touches fixation clip 15, it is formed and inserts tube 11 co-axial tubulars.The internal diameter of base end side that inserts tube 11 is for fixing, and it is and fix, engages the cylindrical portion internal diameter that forms with the footpath for movable half 13,14, only the gradually thin frustum-like shape (taper) of end 11a formation tip formerly.
When utilizing this kind insertion utensil that deformable eyes buitin lens 1 is substituted eyeglass insertion ophthalmic, in switching mechanism 9 open states, intraocular lens 1 is arranged at the lens maintaining part 10 that unloads from the retaining member 12 of apparatus body 5, closing switching mechanism 9 subsequently can make intraocular lens be deformed into less shape, keep under this shape, but the major part beyond the fixing dynamic pressure plate 15,16 of retaining member 12 is flush-mounted in the first end of apparatus body 5 by assembling ditch 5a, and makes above-mentioned pressing plate 15,16 protrude in the top of assembling ditch 5a.
Under this state, retaining member 12 is advanced, pressing plate 15,16 is pressed into the narrow wide portion of assembling ditch 5a, and switching mechanism 9 dresses are taken off assembling freely, insertion tube 11 is given prominence to from the tip of apparatus body 5, can finish inserting the utensil assembling.
According to after above-mentioned assembling finishes, the operation tube 7a of cylindrical shell 7 rearward end of utensil is inserted in turn, make push-off pin 6 shift-in forward that is in going-back position, then can borrow the first end of push-off pin 6 with intraocular lens, the lens maintaining part 10 of self-sustaining member 12 is released via inserting tube 11, and the otch via the about 4mm that is formed at eyeball that continues inserts intraocular lens in the eyeball, this moment, the optic 2 of intraocular lens 1 was to return to the preceding former big shape of distortion by being deformed into little shape attitude by shape memory characteristic.
The apparatus body 5 of above-mentioned insertion utensil, push-off pin 6 and cylindrical shell 7 are the integrally formed product of the flexual synthetic resin of tool for 12 of metal silks system retaining members.
Yet, because inserting with utensil system, above-mentioned traditional intraocular lens will make optic be out of shape the intraocular lens of less shape in the lens maintaining part of retaining member, borrow the push-off pin of ejecting mechanism to go in the eyeball via inserting the tube interpolation, so lens end in the first end of arriving at the insertion tube, system is keeping the shape of being out of shape in the lens maintaining part, can't make optic be deformed into littler shape sharp in the first end of inserting tube, so following problem is arranged.
Promptly, for making intraocular lens otch insertion from childhood ophthalmic, the first end of inserting tube must be made tinyly, must make optic be deformed into littler shape in the lens maintaining part for this reason, be difficulty very but make big shape before the distortion in the lens maintaining part optic is deformed into little shape maturely.Make distortion easily then the size after the distortion than desired size for big, the result inserts the first end gesture of tube must be thicker, this will make lens be difficult to from childhood otch inserts in the eyeball.Therefore, the distortion easiness of lens maintaining part and through little otch inserts intraocular easiness the two can't get both.
The present invention has solved above-mentioned problem via the improvement of inserting tube, provide a kind of lens maintaining part in the retaining member setting can with lens distortion Cheng Gengxiao and simultaneously justice can make and be easy to that via little otch lens are inserted intraocular improvement deformable intraocular lens and insert and use device.
The deformable intraocular lens of the present invention that can reach above-mentioned two purposes simultaneously inserts and has with utensil: the deformable intraocular lens of optic that can decide the deformable elastic system of memory characteristic with having is deformed into little shape and it is remained in the retaining member of the lens maintaining part that has switching mechanism; The ejecting mechanism that the intraocular lens that utilizes push-off pin will remain in the said lens maintaining part is released; And, it is characterized by in that the elder generation of the lens maintaining part of above-mentioned retaining member is distolateral and be connected with one and above-mentioned intraocular lens can be divided into most sections by above-mentioned maintaining part to first end opening and be out of shape and make it become the used insertion tube of littler shape in order to the apparatus body of this ejecting mechanism and above-mentioned retaining member to be installed.
Deformable intraocular lens of the present invention inserts uses utensil, as shown in Figure 3, system will be arranged at the top of the distolateral insertion tube of the elder generation of lens maintaining part of retaining member, form a par from the intermediate portion to first end, and the first end that will insert tube forms to the gradually thin truncated cone portion of tip, utilize ejecting mechanism optic to be become the intraocular lens propelling movement of little shape with push-off pin in the lens maintaining part, and make this optic be deformed into littler shape in above-mentioned par, and then be deformed into littler shape once again in the above-mentioned portion of pulling out that pushes away, promptly in inserting tube, divide most sections to make the intraocular lens distortion become institute's phase size after by in the otch insertion eyeball.
Therefore, tying up to the lens maintaining part according to the present invention is deformed into above-mentioned conventional case intraocular lens onesize, so can make lens distortion easily in above-mentioned maintaining part, become littler shape in inserting a lens that endogenous cause of ill mark section is out of shape above-mentioned maintaining part simultaneously, so can make more tinyly than conventional case with inserting the first end opening of tube and near part thereof, the result can insert anamorphote in the eyeball via less otch.
