Abstract
The utility model relates to an aid for operations, in particular to a positioner for eye pupil operation of ophthalmology, and provides a sclera positioner assisting in intraocular lens sclera suture fixation operation, aiming to solve the problem that two loops of the intraocular lens cannot be guaranteed to rightly fix at 180-degree position of cornea center in existing operations.
Description
Technical field
This utility model relates to a kind of operation auxiliary implement, the locating apparatus of using when specially referring to the operation of ophthalmology pupil.
Background technology
Intraocular lens (IOL) implant surgery is the effective ways that various aphakia patients finally recover efficient visual acuity.Suture fixation of intraocular lens implantation in posterior chamber is capsule without issue or the ordinary operation of the residual rear capsule of periphery when being not enough to support the artificial intraocular lenses.Wherein the sclera suture fixation is the most frequently used modus operandi.2 scleral flaps of classics are the IOL suspension fixedly, and the purpose of operation is IOL to be sewed up be fixed in the ciliary groove, and the fixing position of crystalline lens two buttons loop is just in time spent through 180 of CC.But owing to only depend on episcleral relative 2 fixing two buttons loop of IOL, see clinically crystal displacement, the eccentric problem of optical center, the point that determines crystal positions is not the point of the outer inserting needle of sclera, but 2 points in the wall of eyeball, even outside point has aligned, 2 lines of eyeball inwall do not pass through the center, the position of crystal also will be eccentric (when pin passes the scleral walls deflection, 2 lines of inwall can not pass through the center, also can cause the crystal off normal, the position can not be ajusted by the degree of tightness of adjusting line).
Summary of the invention
Goal of the invention of the present utility model is: the sclera localizer when a kind of indirect labor's crystalline lens sclera suture fixing operation is provided solved in the past and can not guarantee the 180 degree problems that CC is just in time passed through in the fixing position of crystalline lens two buttons loop in the mobile phone.
For finishing the foregoing invention task, sclera localizer when this utility model is achieved in that a kind of indirect labor's crystalline lens sclera suture fixing operation, it is characterized in that: it comprises handle and location circle body, described handle is connected with the location circle body, the location circle body matches with people's pupil size, is arranged with at least two positioning tooths outside circle body; Described positioning tooth is divided circumference equally, and its line passes the center of circle.The size of centring ring can be made several side's styles and size in this patent, can be according to large extremely several of people's eyeball, make respectively a few money patterns, thereby when operation, according to patient's difference, select corresponding style, this patent is by mould customized, the point that will locate in advance is fixed on the centring ring by the form of positioning tooth, allows in advance the fixing position of crystalline lens two buttons loop just in time spend through 180 of CC.Just quite made things convenient for when using like this, as long as with above the mould cover, tap gently, produced the corresponding marking thereby allow on the eyeball, to make things convenient for the location of back.
It is an annulus that technique scheme is made the described location of further refinement circle body, and described annulus has certain height, described positioning tooth is fixed on the periphery of annulus, and crown is lower than annulus, forms four positioning tooth feet at grade.This programme can be implemented on the eyeball realizes marking location, thereby the sclera localizer when taking indirect labor's crystalline lens sclera suture fixing operation away still has the marking to exist, thereby more is conducive to the operation of performing the operation.
The root that technique scheme is done further to improve at handle is provided with anti-skidding volution.The top of handle is a cylindrical lever, is provided with a long bar that lacks at cylindrical lever.This programme adopts above-mentioned handle can remember the only landing of utensil; Frictional force when increasing operation, thereby the safety of assurance operation.
Technique scheme is done further to improve, and described positioning tooth is four.In described centring ring, be provided with the cross reference line that passes the center of circle, the junction point of described cross reference line and centring ring and positioning tooth sequence.In mobile phone, the fixing of this point only do not need two sometimes, sometimes can need a plurality ofly yet, and this programme has adopted mode commonly used, is provided with 4 points thereon.
Description of drawings
Fig. 1 is overall structure sketch map of the present utility model.
Fig. 2 is the top view of centring ring.
The specific embodiment
In order to illustrate further structure of the present utility model and advantage, below in conjunction with accompanying drawing this utility model patent is further described.
As shown in the figure, the sclera localizer during a kind of indirect labor's crystalline lens sclera suture fixing operation,
It comprises handle 2 and location circle body 1, and described handle 2 is connected with location circle body 1, and location circle body 1 is an annulus 11, and described annulus has certain height, and the location circle body matches with people's eyeball size, is arranged with at least two positioning tooths 12 outside circle body; Described positioning tooth 12 is divided circumference equally, and its line passes the center of circle.Positioning tooth is fixed on the periphery of annulus, and crown is lower than annulus, forms four positioning tooth feet at grade.In described centring ring, be provided with the cross reference line that passes the center of circle, junction point and the positioning tooth sequence of described cross reference line 13 and centring ring.Be 135 degree angles between described handle and the centring ring.Root at handle 2 is provided with anti-skidding volution 22.The top of handle is a cylindrical lever, is provided with a long bar 21 that lacks at cylindrical lever.Utilize above-mentioned localizer operating procedure as follows: 1. with sclera localizer location, strictly measure the predetermined sclera position of secondary suspensory intraocular lens (2 and 8 orientation of sclera, during measurement behind cornea center, location, the limbus of corneae 2mm position).2. centered by 2 of sclera localizer location, respectively 2: 8 o'clock the place do and be about 2mm, triangle scleral flap take corneoscleral junction as substrate, do corneosclera 5mm otch 11 o'clock; 3. 2 vertical sclera inserting needles of locating from the sclera localizer with the staight needle of 10-0 polypropylene suspention line, the 1ml syringe needle is from 8 vertical sclera inserting needles of sclera localizer location, the polypropylene pin enters in the 1ml syringe needle of hollow, via the syringe needle guiding, go out pin from 8 scleras.4. draw polypropylene suspention line with Tweezers for eye surgery through corneal incision, cut off from the centre.5. suspend suture in midair through the knotting of threading a needle of fastening with a rope, string, etc. up and down with polypropylene respectively, implant crystal from corneal incision, tension below scleral valve anchor suture; 6. close the sclera conjunctival incision.Art finishes.
