Description

The iris suture device

Technical field

This utility model relates to a kind of iris suture device.

Background technology

Iris suture operation is one of routine operation clinically, and sewing method of the prior art is generally: penetrate from a side angle film with minute hand; After getting into ophthalmic; Pass and tear the iris both sides of the edge, pass from the offside cornea then, the direction that minute hand carries out is vertical with the direction of iridocoloboma.Cut off the suture needle of line end, implant otch from last square crystal, with lenticular hook the suture two ends are pulled out from ophthalmic, after the knotting, the two ends of elastic threads slowly are pushed into iris breach place with the toe-in of accomplishing fluently with artificial intraocular lenses's position adjuster outside otch; And then use the same method and make a call to second and tie and push ophthalmic, be i.e. Mc Cannel method.But there is following defective in it: the tractive to iris is bigger, line end pull out the use lenticular hook, push and use artificial intraocular lenses's actuator, be easy to damage iris and corneal endothelium.

Iris suture is fixedly in the posterior chamber intraocular lens operation; By the corneal incision inserting needle; Near lens haptics, pass perimembranous in the iris, walk around lens haptics to back room, pass iris through the offside of this button loop and return the anterior chamber; Pass the periphery cornea and go out pin, line end pulls out that to push method and the iris suture operation of ophthalmic similar with toe-in.

In the prior art,, only be the difference of method, the special-purpose apparatus of iris suture operation is not arranged though the sewing method of some improvement is arranged.

Summary of the invention

To above-mentioned prior art, this utility model provides a kind of medical apparatus and instruments that is specifically designed to the iris suture operation, that is: iris suture device.

This utility model is realized through following technical scheme:

The iris suture device comprises iris suture holder and toe-in pusher, and wherein, the iris suture holder comprises handle and fixed bar, and fixed bar is connected with handle, and the fixed bar end is provided with " Y " type bifurcated; The toe-in pusher comprises handle and push rod, and push rod is connected with handle, and the push rod end is provided with toe-in shelves bolt, and toe-in shelves bolt end is provided with boss, because the existence of toe-in shelves bolt and boss forms groove in toe-in shelves bolt both sides.

Use: as when carrying out the reparation of iris laceration, operation as follows: at the transparency cornea otch of iridorhexis side work one about 1.5mm, the iris suture holder gets into the anterior chamber from otch; With " Y " type bifurcated stationary burst iris edge; Penetrate from a side angle film with minute hand then, behind the entering ophthalmic, pass and tear the iris both sides of the edge; Pass from the offside cornea then, the direction that minute hand carries out is vertical with the direction of iridocoloboma.Remove holder, cut off the suture needle of line end, the suture two ends are pulled out from ophthalmic with the vertical groove of toe-in pusher from otch, after the knotting, the two ends of elastic threads slowly push to iris breach place with the toe-in of accomplishing fluently with the vertical groove of toe-in pusher outside otch; Using the same method pushes ophthalmic with second knot, and operation is accomplished.

The iris suture device of this utility model comprises two apparatuses: iris suture holder and toe-in pusher, and iris received the tractive degree when iris suture holder can reduce iris suture, was convenient to thread a needle at iris; The toe-in pusher makes things convenient for the propelling movement with toe-in of pulling out of line end, owing to be blunt nosed, safer in anterior chamber's turnover.

The iris suture device of this utility model is applied in the threading knotting of iridoplasty and iris fixation posterior chamber intraocular lens; In operation, use at present, facts have proved, unite and use these two apparatuses to be beneficial to stitching; And saving operating time; Time can foreshorten to original 1/3, because alleviated the stimulation to iris and corneal endothelium, has reduced post-operative complication.

It should be noted that the operation that the iris suture requirement is meticulous, the patient must have consummate operation skill, keeps airtight anterior chamber, keeps normal intraocular pressure; Iris suture minute hand gets into the anterior chamber will avoid corneal endothelial damage.Incorrect operation can cause a lot of complication, as:

(1) hemorrhage: as if tractive iris strength is excessive, can to cause bleeding in the art.

(2) iris damage: incorrect operation often brings the iris damage in the art, and for example iris scissors is hindered, torn, iris is deviate from, iris pigment takes off mistake etc.

(3) corneal injury: common reason has when separating and cutting off anterior synechia, and apparatus inwardly passes in and out number of times too much or too near posterior surface of cornea, but its tip corneal endothelial damage and descemet's membrane.

(4) lens damage: because misoperation, especially when the anterior chamber is more shallow, but the instrument tip direct friction, oppress or puncture anterior lens capsule.

(5) apparatus suspensorius lentis fracture, vitreous body are deviate from: during iridodiastasis, apparatus suspensorius lentis exposes.If apparatus passes in and out the anterior chamber repeatedly at this position, can damage Suspensory ligament and cause vitreous body and deviate from.

(6) uveitis: its reason is because apparatus passes in and out the anterior chamber repeatedly, and operations such as separation, tractive, excision, incision and stitching iris have damage in various degree to stimulate to iris.

Therefore, when operation, operation should be light and handy, avoids as far as possible or alleviate iris damaging.

The iris suture device of this utility model, for being used for the special equipment of iris suture operation, it has advantages such as simple in structure, easy to use, that result of use is good, and suggestion is applied.
