The needle holder cooperates with the suture needle (1), which is connected with the suspension wire (8), the intraocular lens is fixedly connected with the suture needle (1) through the suspension wire (8), the needle holder is composed of a needle head (2), a needle seat (3) and a handle (4), the needle head (2) has an internal hollow needle tube structure, and is arc-shaped corresponding to the suture needle (1), the needle seat (3) is connected between the needle head (2) and the handle (4), a magnetic block is arranged at a connecting position of the needle seat (3) and the needle head (2). According to the invention, the operation is easy to realize, the operating time can be saved, and the safety is good.
Description
Technical field
The invention belongs to ophthalmic medical instrument, be specifically related to a kind of suspention artificial crystal device of easy implantation.
Background technology
The most row extracapsular cataract extractions of cataract operation or ultrasonic emulsification (phaco) method of modern ophthalmology are extractd cataract, after this retain complete crystal pouch, with implantable artificial crystal (lol).In clinical operation, if posterior lens capsule breaks or during crystal Suspensory ligament dialysis, pogoniasis is implanted suspention artificial intraocular lenses, the more general artificial intraocular lenses's of this artificial intraocular lenses feature is, its crystal loop has aperture, can frap by this hole threading, and its stitching is fixed in the ciliary groove of eyeball in art.
Existing suspention artificial crystal device is independent artificial intraocular lenses and with the suspention line of Curved seaming needle, suture needle and artificial intraocular lenses are the structure being separated from each other, in art, need under the microscope respectively two Curved seaming needles to be connected with two crystal loop apertures by suspention line, then by two Curved seaming needles respectively in eyeball ciliary groove pass outside nose temporo side sclera.Now, because of opereating specification limitation, sclera toughness is strong, suture needle institute is changeable through the tortuous direction of route, therefore operation is very difficult and dangerous, careless slightly, just can cause the great complication such as eyeball internal hemorrhage, retina shedding, operation time is long, operating difficulty and dangerous large.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, a kind of processing ease safe easy implantation suspention artificial crystal device of realizing, save time is provided.
The present invention is achieved in that a kind of easy implantation suspention artificial crystal device, comprises artificial intraocular lenses, suspention line, Curved seaming needle and connects pin device, and connect pin device and match with suture needle, suture needle is connected with suspention line, it is characterized in that:
Described artificial intraocular lenses is connected and fixed by suspention line and suture needle;
The described pin device that connects consists of syringe needle, needle stand and handle, and the needle tubing structure that syringe needle is boring, has the radian corresponding with suture needle, and needle stand is connected between syringe needle and handle, and the position that needle stand is connected with syringe needle arranges magnetic piece.
As a further improvement on the present invention, the connection angle between needle stand and handle is preferably 140 °.
Advantage of the present invention is:
1, artificial intraocular lenses is connected and fixed by suspention line and suture needle, omitted perform the operation in the troublesome operations of microscope underpass, shortened operating time.
2, the present invention designs the special pin device that connects, in suture needle, enter after ciliary groove, the sharp spike that connects pin device front end is punctured into ciliary groove and suture needle junction from ready-made triangle below scleral valve, because magneticaction syringe needle and suture needle are easily joined, Curved seaming needle is penetrated to syringe needle tube intracavity, under magnetic piece magnetic force and the drive of operator's external force, easily suture needle is taken out of outside eyeball.The present invention by connect pin device directly from eyeball below scleral valve thrust ciliary groove suture needle taken out of, highly difficult high risk operation is to the transformation of simple and safe method from ciliary groove passes sclera to have realized suture needle, operating time is short, safety is good.
3, the connection angle between needle stand and handle is preferably 140 °, and through practice test, this angle is conducive to surgical staff operation, can further save operating time, improves surgical effect.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
In figure: 1, suture needle, 2, syringe needle, 3, needle stand, 4, handle, 5, magnetic piece, 6, optic, 7, crystal loop, 8, suspention line.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
As shown in the figure, artificial intraocular lenses consists of optic 6 and the crystal loop 7 that is connected to optic 6 upper and lower parts.The two ends of suspention line 8 are connected and fixed with suture needle 1 and crystal loop 7 respectively.Suture needle 1 adopts and is suitable for arriving through lesser ring of Merkel from top corneosclera otch the arc of ciliary groove.Connect pin device and consist of syringe needle 2, needle stand 3 and handle 4, syringe needle 2 is that front end is sharp, the needle tubing structure of boring, has the radian corresponding with suture needle 1, and needle stand 3 is connected between syringe needle 2 and handle 4, and the position that needle stand 3 is connected with syringe needle 2 arranges magnetic piece 5.Needle stand 3 is connected with 140 ° of degree angles with handle.
Occupation mode of the present invention is: complete cataract extraction, carry out eyeball top corneoscleral junction otch and both sides triangle scleral flap, by suspention artificial intraocular lenses optic 6 be placed in top otch near, left-handed pin device, 1/3 place after clamping in suture needle 1, from top, otch enters anterior chamber of eyeball, through lesser ring of Merkel, enters ciliary groove, and needle point rushes right side; The right hand is held and is connect pin device handle 4, connecing pin device syringe needle 2 punctures from right side below scleral valve, enter ciliary groove and suture needle 1 junction, suture needle 1 is aligned and penetrated in syringe needle 2 needle tubings, under the magnetic attraction of magnetic piece 5, suture needle 1 is positioned in syringe needle 2 needle tubings preferably, then by two Handball Association's active forces, suture needle 1 is pulled out from eyeball right side below scleral valve.The suture needle 1 another being connected with crystal loop 7 with method is pulled out from eyeball left side below scleral valve, and optic 6 is implanted to ciliary groove.Tension both sides suspention line 8, is fixed on below scleral valve.
Operation technique of the present invention is simple, has saved the threading step of general artificial intraocular lenses while implanting, and particularly simplifies difficult complexity and dangerous operation when having improved suture needle 1 and passing in eyeball, and safety is time saving and energy saving.
