Abstract
The present invention provides a kind of choroid restorers, including casing, guidance needle and fixed strip band, described sleeve pipe front end to be equipped with the through-hole for traversing casing, and the guidance needle is movably set in casing, and the fixed strip band penetrates to be pierced by by through-hole to be flexibly connected with casing；The choroid restorer, structure is simple, simple and quick, suitable for the reset of various and different parts outer choroidal detachments, has very important clinical practice meaning.
Description
Technical field
The present invention relates to the field of medical instrument technology, especially a kind of choroid restorer.
Background technique
Eye traumas can lead to choroidal a variety of damages, and such as choroidal serosity or hemorrhagic are detached from, choroid is broken
It splits, choroid dialysis, choroid bullet wound, choroid splitting, the coloboma of choroid, choroid shortens and holes etc..A portion
Case development is choroidal permanent disengaging.Choroidal this damage not only influences the visual function of patient, is also unfavorable for hurting
The eyeball structure of eye restores and intraocular pressure maintains, and the height of intraocular pressure directly determines that can hurt eye get rid of the strategic point of atrophia bulbi
Fortune.It is different from retina, choroid histologically elastic fibers and collagenous fibres rich in.Choroidal histology is special
Point determines tela chorioidea once being broken, and elastic fibers bounces back, and the choroid cripetura of dialysis is made to be difficult to paste with sclera again
It is attached.Therefore, the reparation of choroidal injury is both important in the treatment of eye traumas and unusual stubborn problem.
Currently, for the reparation of traumatic detachment of choroid, shortening, lacerated wound, there are several types of methods:
1. biological glue bond, this method is mainly seen in case report, and there are intraocular safety issue, clinical application effects
Fruit be not it is especially desirable, it is not expanded.
The close the break 2. sclera pressurizes, this method are primarily adapted for use in lesser choroid ceasma.
3. choroid suture is fixed, this method is suitable for the reset of large range of choroidal detachment, but complicated for operation, damage
Wound is big, is easy to bring new complication.The operation is to determine the model of choroid dialysis under illumination within the eye after vitreous excision
It encloses, and is sutured in corresponding sclera by scleral surface inserting needle, but not enough precisely.Disadvantage is that: on the one hand, suture
The large bending needle entrance needed is not intraocular easy to operate, be easy to cause the damage of its hetero-organization；On the other hand, suture needle needs to pass through repeatedly
Sclera passes in and out eyeball, larger to the damage of eyeball.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of choroid restorer.
In order to solve the above technical problems, the technical scheme is that
A kind of choroid restorer, including casing, guidance needle and fixed strip band, described sleeve pipe front end are equipped with and traverse casing
Through-hole, the guidance needle are movably set in casing, and the fixed strip band penetrates to be pierced by by through-hole to be flexibly connected with casing.
Preferably, above-mentioned choroid restorer, described sleeve pipe material are artificial lens haptics material.
Preferably, above-mentioned choroid restorer, described sleeve pipe material be polyimides (high temperature resistant up to 400 DEG C or more, for a long time
Use temperature range -200~300 DEG C) or TECNIS polymethyl methacrylate (PMMA, fusion temperature: 240~270 DEG C).
Preferably, above-mentioned choroid restorer, described sleeve pipe leading edge hole diameter are slightly larger than choroidal structure to be fixed.
Preferably, the material of above-mentioned choroid restorer, the guidance needle is titanium.
Preferably, above-mentioned choroid restorer, the material of the fixed strip band are polymethyl methacrylate.
Preferably, above-mentioned choroid restorer, the diameter for retaining in intraocular and fixed choroidal fixed strip band, which is less than, to be worn
The thorn outer diameter of casing.
The beneficial effects of the present invention are:
Above-mentioned choroid restorer, structure is simple, simple and quick, suitable for various and different parts outer choroids
The reset of disengaging has very important clinical practice meaning.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of choroid restorer of the present invention.
Fig. 2 is the application schematic diagram of choroid restorer of the present invention.
In figure: 1- casing 2- guides needle 3- fixed strip band
Specific embodiment
Technical solution of the present invention is further described combined with specific embodiments below.
Embodiment 1
As shown in Figure 1, a kind of choroid restorer, including casing 1, guidance needle 2 and fixed strip band 3, described sleeve pipe material
For polyimides (high temperature resistant up to 400 DEG C or more, -200~300 DEG C of long-term use temperature range), that TECNIS also can be used is poly-
The artificial lens haptics material such as methyl methacrylate (PMMA, fusion temperature: 240~270 DEG C)；It is described guidance needle material be
Titanium；The material of the fixed strip band is polymethyl methacrylate；Wherein, described sleeve pipe front end, which is equipped with, traverses the logical of casing
Hole, the guidance needle are movably set in casing, and the fixed strip band penetrates to be pierced by by through-hole to be flexibly connected with casing, are retained
It is less than the outer diameter of puncture casing in the diameter of intraocular and fixed choroidal fixed strip band, described sleeve pipe leading edge hole diameter omits
Greater than choroidal structure to be fixed.
In use process, as shown in Fig. 2, casing 2 is passed through sclera in the case where guidance needle 3 guides first, instrument is helped within the eye
The choroid across disengaging is helped down, by the through-hole of 1 threading of fixed strip band, 2 front end, fixed strip band can pass through casing front end
Hole, the process that casing is pulled out outward will drive fixed strip band, and fixed strip band can attach choroid and sclera, repeat into
Row operation is pulled out casing 2 up to fixed strip band 2 is by choroid and sclera outward until disengaging choroid is completely covered in fixed strip band
It is attached onto completely, suture wire size 7-0 is absorbable suture, and the extra of outer end is wiped out in 2 outer end of suture fixed sleeving to sclera
Casing 2.
Above-mentioned reference embodiment is illustrative rather than limits to a kind of detailed description that choroid restorer carries out
Property, can enumerate several embodiments according to limited range, thus the variation in the case where not departing from present general inventive concept and
Modification, should belong within protection scope of the present invention.
