The front end of the rinsing needle is closed; the top end of the needle does to need to be moved between corneal layers, and the cellular damage to corneal stroma is reduced. When the needle slides forward and backward, the rinsing for the upper part and the lower part between the corneal layers and the moistening for the surfaces of the corneal layers can be finished; a plurality of operating procedures can be finished at one time and the operative time is saved; and the cellular damage to corneal stroma is reduced while the moistening protection to corneas is finished, so that the operation is safer and faster.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments that is applied to excimer laser surgery field, particularly a kind ofly in excimer laser refractive situ keratomileusis (LASIK) art, use Syringe needle Irrigator.
Background technology
The Syringe needle Irrigator of applying in keratectomy is at present common passivity Syringe needle Irrigator, flushing liquor directly flows out foremost from syringe needle, in art, washing time is long, be difficult for cornea chip to rinse well completely, syringe needle can cause the damage of keratocyte in the movement of interlayer, and can not row anterior corneal surface when interlayer cornea rinses moistening, surgical operation step is many.
Summary of the invention
The object of this invention is to provide a kind of damage that reduces stromal cells, while sliding before and after syringe needle, just can complete the moistening of the upper and lower flushing of inter-lamination of cornea and anterior corneal surface, once complete in the excimer laser refractive situ keratomileusis art of a plurality of operating procedures and use Syringe needle Irrigator.
For achieving the above object, the technical solution used in the present invention is:
In a kind of excimer laser refractive situ keratomileusis art, use Syringe needle Irrigator, comprise: needle handle, the tail end of needle handle is with syringe Connection Block, it is characterized in that: a side and the needle handle of needle handle head end be in 90 °～and 120 ° of angle directions are provided with two syringe needles, and two syringe needles are respectively syringe needle and lower syringe needle; Needle handle is what communicate with upper syringe needle and lower syringe needle, the front end sealing of upper syringe needle and lower syringe needle; Upper syringe needle be provided with below 2 apopores, lower syringe needle be provided with 3 apopores above, lower syringe needle be provided with 5 apopores below.
According to using Syringe needle Irrigator in described excimer laser refractive situ keratomileusis art, it is characterized in that: 2 apopores below described upper syringe needle and the diameter of lower 3 apopores above syringe needle are 0.2mm; The diameter of 5 apopores below described lower syringe needle is 0.4mm; Described needle handle (4) head end one side becomes 120 ° of angle directions that two described syringe needles are set with needle handle.
According to using Syringe needle Irrigator in described excimer laser refractive situ keratomileusis art, it is characterized in that: the diameter 1.2mm of described needle handle; Described upper syringe needle 1 and lower syringe needle 2 be long 10mm all, and diameter is 0.6mm, spacing 0.3mm between upper syringe needle and lower syringe needle.
Syringe needle Irrigator front end sealing of the present invention, needle tip, without moving at inter-lamination of cornea, has reduced the damage of stromal cells.While sliding before and after syringe needle, just can complete the moistening of the upper and lower flushing of inter-lamination of cornea and anterior corneal surface; once complete a plurality of operating procedures; saved operating time; can be according to requiring to control flushing liquor flow in art; save flushing liquor; can when alleviating stromal cells damage, complete the moistening protection of corneal, in art, can remain the clear of corneal transparency and operating field, make to perform the operation safer, quick.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
In excimer laser refractive situ keratomileusis art of the present invention, use Syringe needle Irrigator using state as shown in Figure 1, comprise: needle handle 4, the tail end of needle handle 4 is with syringe Connection Block 5, one side and the needle handle of needle handle 4 head ends be in 90 °～and 120 ° of angle directions are provided with two syringe needles, preferably 120 ° of a side of needle handle 4 head ends and needle handle angles.Two syringe needles are respectively syringe needle 1 and lower syringe needle 2; Needle handle 4 is what communicate with upper syringe needle 1 and lower syringe needle 2, the front end sealing of upper syringe needle 1 and lower syringe needle 2.
As shown in Figure 1, Figure 2, Figure 3 shows, upper syringe needle 1(distinguishes upper and lower syringe needle with Fig. 1 using state of the present invention) be provided with below 2 apopores 7, lower syringe needle 2 be provided with 3 apopores 3 above, lower syringe needle 2 be provided with 5 apopores 6 below.
The diameter of 2 apopores 7 below upper syringe needle 1 and lower syringe needle 23 apopores 3 is above 0.2mm.The diameter of lower syringe needle 25 apopores 6 is below 0.4mm.
The diameter 1.2mm of needle handle 4; Upper syringe needle 1 and lower syringe needle 2 be long 10mm all, and diameter is 0.6mm, spacing 0.3mm between upper syringe needle 1 and lower syringe needle 2.
The invention discloses a kind of in excimer laser refractive situ keratomileusis (LASIK) art with Syringe needle Irrigator, this syringe needle has needle handle, syringe needle and apopore to form, after connect 5ml syringe.Syringe needle divides upper and lower two parts, and during operation, excimer laser lobe, between upper and lower syringe needle, can be taken into account excimer laser subcornea wash and anterior corneal surface moistening.Under lobe, syringe needle has upper and lower apopore, lower apopore flow is larger, can fully rinse the cornea chip that laser causes, upper water-out hole flow is slightly little, can reduce the damage of current stromal cells, and on lobe, the Syringe needle Irrigator water yield is less, when doing inter-lamination of cornea flushing, cornea can be completed moistening, in art, can better keep corneal transparency and prevent bitot's patches in art, making to get a clear view in operative process, performing the operation safer, quick.
