Abstract
This utility model relates to a kind of pupil spreader in ophthalmic medical utensil field, the tetragon becket that comprises the smooth sealing that the length of side made by medical stainless steel silk is 5～6mm, four drift angle places of described tetragon becket bend respectively a spiral mouth circle helical ring toward the outer side, the pitch of described spiral mouth place helical ring is 1～1.2mm, and the diameter of described stainless steel silk is 0.05～0.08mm.Pupil spreader of the present utility model, the helical ring at four jiaos of places of tetragon becket, spiral mouth is outwardly for strutting and block the edge of pupil to periphery, in pupil dilation operation, as long as pupil edge is supported between the spiral mouth of four helical rings, just can be by tetragon becket by platycoria, in operation, the loading or unloading operation of pupil spreader is convenient, to pupil and iris not damaged, greatly improved the safety of ophthalmologic operation, reduce post-operative complication, and pupil spreader of the present utility model is reused after adopting metal material to make repeatedly autoclave sterilization.
Description
Technical field
This utility model relates to ophthalmic medical utensil field, a kind of pupil spreader while particularly needing because pupil is little in various ophthalmologic operations manually to expand pupil.
Background technology
Clinically, carry out, in the ophthalmologic operation in microcoria situation that a variety of causes causes, need to carrying out pupil dilation operation, to reduce medical apparatus contact iris, cornea, crystalline lens or other position etc., corresponding position is caused the risk of damage.The method of pupil dilation of the prior art, has plenty of to adopt and drip mydriatic, but mydriatic is inoperative to a part of patient, does not reach the object of pupil dilation; Have plenty of directly pupillary margin otch, can cause postoperative pupil irregular loose large, the complication such as patient's photophobia; The employing iris hooks also having is carried out pupil dilation, and this kind of method can additionally increase by 4 short keratonyxis mouths in art, and placement and taking-up drag hook time are long, and corneal causes additional injuries, corneal astigmatism to affect patient's visual quality.
Utility model content
The problem that this utility model exists for pupil dilation operation of the prior art, provides a kind of simple in structure, easy to operate, and can effectively reduce the pupil spreader of postoperative damage and complication.
The purpose of this utility model is to realize like this, a kind of pupil spreader, the tetragon becket that comprises the smooth sealing that the length of side made by medical stainless steel silk is 5～6mm, four drift angle places of described tetragon becket bend respectively a spiral mouth circle helical ring toward the outer side, the pitch of described spiral mouth place helical ring is 1～1.2mm, and the diameter of described stainless steel silk is 0.05～0.08mm.
Pupil spreader of the present utility model, the helical ring at four jiaos of places of tetragon becket, spiral mouth is outwardly for strutting and block the edge of pupil to periphery, in pupil dilation operation, as long as pupil edge is supported between the spiral mouth of four helical rings, just can be by tetragon becket by platycoria, in operation, the loading or unloading operation of pupil spreader is convenient, to pupil and iris not damaged, greatly improved the safety of ophthalmologic operation, reduce post-operative complication, and pupil spreader of the present utility model is reused after adopting metal material to make repeatedly autoclave sterilization.
As improvement of the present utility model, described tetragon becket is foursquare.
As further improvement of the utility model, the internal diameter of described helical ring is 1～1.5mm.
As of the present utility model, further improve, described stainless steel silk is that diameter is the titanium alloy wire of 0.05mm.
Accompanying drawing explanation
Fig. 1 is the structural representation of pupil spreader of the present utility model.
Fig. 2 is that the A of Fig. 1 is to the partial enlarged drawing of projection.
Fig. 3 is for adopting the block diagram of pupil spreader expansion pupil of the present utility model.
Fig. 4 is the block diagram that pupil spreader takes out.
The specific embodiment
Be pupil spreader of the present utility model as depicted in figs. 1 and 2, the tetragon becket 1 that comprises the smooth sealing that the length of side made by medical stainless steel silk is 5～6mm, four drift angle places of its tetragon becket bend respectively a spiral mouth circle helical ring 2 toward the outer side, the pitch of spiral mouth place helical ring 2 is 1～1.2mm, and the diameter of stainless steel silk is 0.05～0.08mm.In the present embodiment, the titanium alloy wire that the wire diameter of selecting is 0.05mm, being bent into the length of side is the square-shaped metal ring of 5.6mm, the internal diameter of four drift angle place helical rings 2 is 1.2mm.
Block diagram when pupil spreader is implanted and taken out while carrying out pupil dilation operation for employing pupil spreader of the present utility model as shown in Figure 3 and Figure 4, in figure, 3 is pupil, 4 is iris.As shown in Figure 3, when implantation pupil spreader carries out the operation technique of pupil dilation, in 12:00 position and 3:00 position, make respectively the main otch 5 of cornea and the cornea side otch 6 of 3.2 mm, in anterior chamber, inject adhered elastomer filling anterior chamber, get disposable intraocular lens injector, to in chuck, fill adhered elastomer, then pupil spreader is positioned in chuck, close up chuck; Chuck is connected with injector handle; Injector head is inserted to anterior chamber from the main otch 5 of cornea, slowly inject, make the helical ring 2 spiral mouths of a drift angle of pupil spreader block 6:00 position, below pupillary margin, the spiral mouth of drift angle place, both sides helical ring 2 blocks respectively 3:00 position and 9:00 position pupillary margin; Exit injector, from cornea side otch 6 and the main otch 5 of cornea, insert respectively two intraocular lenss card that hook completes 12:00 position pupillary margin of transposing and press, thereby complete the operation of pupil dilation, then carry out cataract ultrasonic emulsification and implantation of artificial lens.Postoperative while need taking out pupil spreader, from the main otch 5 of cornea, insert intraocular lenss' downward push-and-pull of drift angle that hook hooks 12:00 position pupil spreader of transposing, remove the card of pupil outer rim is pressed; Remove respectively again the card of all the other 3 position spiral mouths and press, finally from the main otch 5 use tweezers of cornea, press from both sides out pupil spreader.
While therefore adopting pupil spreader of the present utility model to carry out pupil dilation operation, the loading or unloading operation of pupil spreader is convenient, to pupil and iris not damaged, greatly improved the safety of ophthalmologic operation, reduce post-operative complication, and pupil spreader of the present utility model is reused after adopting metal material to make repeatedly autoclave sterilization.
