Description
Technical field
The present invention relates to a kind of core splitting hook, more specifically, more particularly to a kind of combined type cataract ultrasonic emulsification is crystalline
Body multilayer core splitting hook.
Background technology
In recent years in surgical field, how by minimally invasive theory through turning into the heat of concern in all surgical procedures
Point.Phacoemulsification technique is constantly updated, and is reached its maturity, it has also become the routine operation mode of current cataract therapy, and
And refractive surgery is progressively converted into.How to ensure on the premise of operation safety Reduction surgery otch to greatest extent, reduce super
Acoustic energy, shortens operating time, reduces endothelial cell and loses and tissue damage, improves procedure efficiency, as far as possible earlier
Postoperative best vision is obtained, is the target that all ophthalmic surgeons are pursued.Core splitting hook is to best embody cataract operation doctor
The apparatus of individual character.There are a variety of core splitting hooks in the market and respectively there are advantage and disadvantage, but generally existing splits the relatively low deficiency of core efficiency.Have
Though core splitting hook have double end, bipitch structure is the same, and its function is single, without an apparatus use function.
The content of the invention
It is an object of the invention to for above-mentioned the deficiencies in the prior art there is provided a kind of clever structure, use flexibly and effect
Really good combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook.
The technical proposal of the invention is realized in this way：A kind of combined type cataract ultrasonic emulsification crystalline lens multilayer splits core
Hook, including handle, the first hook portion is provided with handle wherein one end, and the handle other end is provided with the second hook portion, second hook portion
By the second connecting rod, it is vertically set on the core splitting knife of the second connecting rod free end and is disposed on along core splitting knife length direction and split
Some auxiliary knife compositions of core knife blade both sides；The center line and core splitting knife blade of second connecting rod are in the same plane；Positioned at splitting
The auxiliary knife of core knife both sides corresponds V-shaped and mutually corresponding auxiliary knife blade and is oppositely arranged.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook, first hook portion is by head rod
Constituted with the core pin of splitting for being vertically set on head rod free end；It is sphere that this, which splits core pin in conical structure and free end,.
It is relative on the wall of the middle handle side to set in above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook
Recess is equipped with, two recesses are located at core splitting knife blade both sides respectively；It is interval with along its length on the handle of recess both sides
Some anti-slip rings.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook, the length of the core splitting knife is 2-
2.5mm, knife back width is 0.2-0.25mm；Spherical structure is provided with core splitting knife free end；The auxiliary knife being oppositely arranged is along core splitting knife
Length direction is uniform.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook, the auxiliary knife length is 0.2-0.4mm.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook, positioned at core splitting knife blade both sides and relatively
The angle α that the auxiliary knife set is formed is 55 °~65 °.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook, second connecting rod is V-shaped, the V
The angle β of shape is 120 °.
In above-mentioned combined type cataract ultrasonic emulsification crystalline lens multilayer core splitting hook, positioned at homonymy and two two adjacent auxiliary knives
Between spacing be 0.2-0.3mm.
The present invention is using after said structure, by setting the hook structure of two different structures at handle two ends, and existing
Technology is compared, and is had the advantages that following：
(1) wherein one end is coordinated using auxiliary knife with core splitting knife, can be reached and split at many levels disposably by lens nucleus
Lens nucleus is opened, is allowed to more broken, emulsification is more easy to, ultrasonic energy can be saved, shortens operating time, post-operative cornea oedema can be mitigated,
Vision restoration is fast.
(2) auxiliary knife coordinates with core splitting knife, by Multi-contact crystal nuclear, can be allowed in nuclear process is split more steady, especially firmly
Nuclear energy reduces its skidding, can be prevented effectively from the damage of Lens capsular, pouch and iris, beginner uses safer.
(3) anti-slip ring and medial concavity structure are designed on handle, can grip operator more comfortable, more steady.
(4) other end is designed to that head rod is mutually perpendicular to splitting core pin, can conveniently be accustomed to the vertical operation for splitting core
Person.The different shape design of such two end, can be suitable for the operator of different operation customs with an apparatus, or same doctor should
To different types of cataract patient.Therefore both suitable level splits nuclear technology to the core splitting hook of the present invention, is applied to vertically split core again
Technology；Both training equipment cost had been reduced, energy and operating time have been saved again.
(5) core splitting hook of the invention, can substantially accelerate the cutting and grinding of crystal nuclear, emulsify, and effectively fix crystal nuclear, together
When reduce Lens capsular, iris and pouch damage risk.It is easy to use, efficiently, the probability of complication is reduced, reduce operation
Wound, reduces operation risk, is more suitable for beginner, is worthy to be popularized.
