Description
Technical field
This utility model relates to a kind of core splitting hook, more particularly, particularly relates to a kind of combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook.
Background technology
In recent years in surgical field, how Wicresoft's theory is become in all operation processs the focus of concern.Phacoemulsification technique is constantly updated, and reaches its maturity, has become the routine operation mode of current cataract therapy, and be progressively converted into refractive surgery.How to ensure under the prerequisite of operation safety Reduction surgery otch to greatest extent, reduce ultrasonic energy, shorten operating time, reduce endothelial cell to lose and tissue injury, improving procedure efficiency, as far as possible earlier obtain postoperative best vision, is the target that all ophthalmic surgeon are pursued.Core splitting hook is the apparatus best embodying cataract operation doctor individual character.Have multiple core splitting hook in the market and respectively have pluses and minuses, but ubiquity splits core efficiency deficiency on the low side.Though some core splitting hooks have double end, bipitch structure is the same, its function singleness, does not have the function that an apparatus is multiplex.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of structure ingenious, use flexible and respond well combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook.
The technical solution of the utility model is achieved in that a kind of combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, comprise handle, wherein the first hook portion is provided with in one end at handle, the described handle other end is provided with the second hook portion, this second hook portion by the second connecting rod, be vertically set on the second connecting rod free end knife for nucleus cutting and form along the some auxiliary cutter that knife for nucleus cutting length direction is disposed on knife for nucleus cutting blade both sides; Center line and the knife for nucleus cutting blade of the second connecting rod are in the same plane; The auxiliary cutter blade that the auxiliary cutter one_to_one corresponding being positioned at knife for nucleus cutting both sides is V-shaped and mutually corresponding is oppositely arranged.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, described first hook portion is made up of head rod and the core pin of splitting being vertically set on head rod free end; This splits core pin conically structure and free end is sphere.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, in the middle part of described handle, sidewall is relatively set with recess, two recesses lay respectively at knife for nucleus cutting blade both sides; The handle of recess both sides is interval with some anti-slip rings along its length.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, the length of described knife for nucleus cutting is 2-2.5mm, and knife back width is 0.2-0.25mm; Spherical structure is provided with at knife for nucleus cutting free end; The auxiliary cutter be oppositely arranged is uniform along knife for nucleus cutting length direction.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, described auxiliary cutter length is 0.2-0.4mm.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, be positioned at knife for nucleus cutting blade both sides and the angle α that the auxiliary cutter be oppositely arranged is formed is 55 ° ~ 65 °.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, described second connecting rod is V-shaped, and the angle β of this V-arrangement is 120 °.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilamellar core splitting hook, the spacing at homonymy and between two neighbours' two auxiliary cuttves is 0.2-0.3mm.
After this utility model adopts said structure, by arranging the hook structure of two different structures at handle two ends, compared with prior art, there is following advantage:
(1) wherein one end adopts auxiliary cutter to coordinate with knife for nucleus cutting, can be disposable by nucleus lentis, can reach nucleus lentis of riving at many levels, make it more broken, easier emulsifying, can ultrasonic energy be saved, shorten operating time, can alleviate post-operative cornea edema, vision restoration is fast.
(2) auxiliary cutter coordinates with knife for nucleus cutting, and by Multi-contact crystal nuclear, can make it to split in nuclear process more steady, special stone can reduce it and skid, and effectively can avoid the damage of Lens capsular, pouch and iris, abecedarian uses safer.
(3) on handle, design anti-slip ring and medial concavity structure, operator can be made to grip more comfortable, more steady.
(4) other end is designed to head rod and to split core pin mutually vertical, conveniently can be accustomed to the operator vertically splitting core.Such two end difformity designs, can be suitable for the different operator be accustomed to of performing the operation by an apparatus, or same doctor tackle dissimilar cataract patient.Therefore core splitting hook of the present utility model be both applicable to level split nuclear technology, be applicable to again vertically split nuclear technology; Both decrease training equipment cost, again save energy and operating time.
(5) core splitting hook of the present utility model, obviously can accelerate the cutting and grinding of crystal nuclear, emulsifying, effectively fixed crystal core, reduces the risk of Lens capsular, iris and pouch damage simultaneously.Easy to use, efficiently, decrease the probability of complication, reduce operation wound, reduce operation risk, be more suitable for abecedarian, be worthy to be popularized.
