Abstract
The present invention relates to field of medical technology, especially a kind of sclera stay suture fixator, including retainer body, the retainer body is specially that polymethyl methacrylate materials are made, and the entire length of retainer body is 2.4mm, width is 2.2mm, the retainer body is in shuttle-type, limited block is additionally provided with retainer body, and limited block one end is connected with suture, the suture is connected with suture needle through retainer body, and the retainer body is made up of circular central bore, the first neck, the second neck, the 3rd neck with the 4th neck.For the present invention by the more convenient fixed suture of design of the Y type necks of uniqueness, the fixator, which designs, slight radian, can preferably be attached at sclera.
Description
Technical field
The present invention relates to field of medical technology, suitable for lens-dislocation, is particularly suitable for use in and departs from the bigger trouble of scope
Person, more particularly to a kind of sclera stay suture fixator.
Background technology
Crystalline lens relies on its suspensorium and linking for ciliary body and is maintained on certain position, and its malposition has two
Kind reason：First, wound causes zonular breaking, second, congenital apparatus suspensorius lentis hypoplasia or relaxation are powerless,
Luxation or subluxation of the lens can be caused.According to the degree and form of Lens luxation, crystal incomplete dislocation can be divided into and taken off completely
Position.Following complication often occurs after lens-dislocation：Seriously ametropia, uveitis, secondary glaucoma, retina
Disengaging, corneal injury etc..Because the crystal for extracing dislocation is bigger than general cataract extraction risk, blindly operation may cause eyesight
Infringement even eyeball forfeiture.Therefore the therapeutic scheme that should cautiously determine.Traditional operation mode is luxated lens together with crystalline substance
Shape somatocyst bag is extractd together, suspension type artificial lens is implanted into after excision, although having recovered certain visual quality, it is destroyed
Ocular physiology is dissected, while brings a series of complication such as：Bulbi hypertonia, bleeding, artificial lens off normal, suspention thread breakage are manually brilliant
Body falls into vitreous chamber etc., at present, needs to be implanted into a lens capsule being made up of annulus after known eye lens dislocation
Bag tension link, plays a supporting role, but existing sclera stay suture fixator fixes inconvenience, limits its use, it is therefore proposed that
A kind of sclera stay suture fixator.
The content of the invention
The invention aims to solve defect present in prior art, and a kind of sclera suture proposed is fixed
Device.
To achieve these goals, present invention employs following technical scheme：
A kind of sclera stay suture fixator is designed, including retainer body, the retainer body are specially polymethyl
Methyl acrylate material is made, and the entire length of retainer body is 2.4mm, and width 2.2mm, the retainer body is in shuttle
Type, is additionally provided with limited block in retainer body, and limited block one end is connected with suture, and the suture is through retainer body
Suture needle is connected with, the retainer body is by circular central bore, the first neck, the second neck, the 3rd neck and the 4th pocket set
Into.
Preferably, the length of first neck, the second neck, the 3rd neck and the 4th neck is 0.08mm, and the
One neck, the second neck, the 3rd neck and the 4th neck are in Y-shaped.
Preferably, a diameter of 0.08mm of the circular central bore.
A kind of sclera stay suture fixator proposed by the present invention, beneficial effect are：The sclera stay suture fixator passes through uniqueness
Y type necks the more convenient fixed suture of design, have slight radian in fixator design, can preferably be attached at sclera.
Brief description of the drawings
Fig. 1 is a kind of structural representation of sclera stay suture fixator proposed by the present invention.
In figure：It is 1 retainer body, 2 suture needles, 3 the 3rd necks, 4 the 4th necks, 5 second necks, 6 first necks, 7 spacing
Block, 8 sutures.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.
Reference picture 1, a kind of sclera stay suture fixator, including retainer body 1, retainer body 1 are specially poly- methyl-prop
E pioic acid methyl ester material is made, and avoids and eyeball is damaged in prolonged fix, and the entire length of retainer body 1
For 2.4mm, width 2.2mm, retainer body 1 is in shuttle-type, has slight radian in the retainer body 1 design, can be preferably
It is attached at sclera.
It is additionally provided with limited block 7 in retainer body 1, and the one end of limited block 7 is connected with suture 8, suture 8 is through fixation
Device body is connected with suture needle 2, and retainer body 1 is by circular central bore, the first neck 6, the second neck 5, the 3rd neck 3 and the 4th
Neck 4 forms, and the first neck 6, the second neck 5, the length of the 3rd neck 3 and the 4th neck 4 are 0.08mm, and the first neck
6th, the second neck 5, the 3rd neck 3 and the 4th neck 4 are in Y-shaped, and unique Y designs are more convenient to fix suture, and prevents
It comes off.
A diameter of 0.08mm of circular central bore.
In use, sclera stay suture fixator is positioned over into scleral tissue surface, implements suspension type tension link and suspention is artificial
Suture is suspended during crystal in midair after 3.5-4mm scleras pass from after corneoscleral junction, the circular central bore into retainer body 1,
The elasticity of Suture lines adjustment, suspention suture is caught in the first neck 6, suitably adjusts and enters homonymy around sclera stay suture fixator
Another is caught in the second neck 5, is similarly caught in the 3rd neck 3 and the 4th neck 4, is stitched from the 4th neck 4 around the first neck 6
Line card is lived, and wipes out unnecessary suture, and suture head is placed in below sclera stay suture fixator, avoids suture head to conjunctival tissue
Stimulate, reduce the sense of discomfort of patient, suture, which is fixed, to be completed, and bulbar conjunctiva is covered in above fixator, bulbar conjunctiva is sutured, has performed the operation
Into.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
