Abstract
The present invention provide it is a kind of can singlehanded control the trans- scissor core splitting knife of cataract operation, hook-shaped core splitting knife including knife handle one end is arranged in, cutter hub is made of two heads in the component of trans- hook solid, it is blade on the inside of crotch, to lens nucleus of riving, two cutter hubs are combined in scissor-shaped, and the scissor separation on core splitting knife head is realized by stirring the fastener being arranged on knife handle.The present invention can not only be stablized by the cutter head of trans- crotch-shaped holds crystal nuclear, but also the folding dynamics of cutter head can be effectively controlled by scissors control, achievees the purpose that voluntarily to separate crystal nuclear, to improve the safety and efficiency for splitting core by hand.
Description
Technical field
The invention belongs to medical instruments field, in particular to it is a kind of can singlehanded control trans- scissor core splitting knife, can answer
For in phacoemulsification art.
Background technique
Cataract refers to that intraocular crystalline lens because muddiness occurs for a variety of causes such as aging, physical and chemical damage, inflammation, is become by transparent
It is opaque, it hinders light to enter intraocular, is common blinding eye disease to affect vision.In current technology, hand
Art is unique effective ways of cataract therapy.Phacoemulsification is common mainstream art formula, hand in Present clinical
Art Shi doctor usually makes the cornea of 1.8~3.0 mm lengths or angle Gong Yuan notch, the equipment for then protruding into pen tip size are answered
It will be absorbed after muddy lens emulsification with ultrasonic energy, retain posterior lens capsule, and be implanted into accommodative foldable intraocular lens to compensate
The dioptric of natural lens acts on.Cataract surgery has that wound is small, notch does not have to suture, after-operation response is light and vision restoration
The advantages that fast.
When carrying out phacoemulsification, it usually needs will be white by the force action of super newborn syringe needle and core splitting hook
Cataract or glaucoma " is divided and rule ", and the lens nucleus of entire muddiness is both divided into several small core blocks and carries out emulsification absorption, to improve super
The validity and safety of breast conserving surgery.It splits and needs steadily hold using super newborn energy is rightly held in nuclear process
Core block is held, avoids capsule after excessive ultrasound injury again, it is therefore desirable to longer learning curve.Compared with conventional super newborn fragmentation nucleus,
Nuclear technology is split in pure craft can be greatly decreased phaco time, reduce damage of the ultrasonic emulsification for corneal endothelium.It is good
Manual core splitting knife should meet two conditions: 1, super newborn syringe needle can be replaced to cooperate core splitting hook, stablize and hold core block, crystal nuclear is avoided to revolve
Turn, overturning；2, pyrene dynamics can be controlled by one hand.
Summary of the invention
To solve the above-mentioned problems, it is promoted and splits nuclear safety and efficiency, conveniently split core operation, the present invention provides one kind can be with
The trans- scissor core splitting knife of one hand control, the core splitting knife is simple for structure, the core splitting knife body equipped with scissors shape, and can pass through one hand
Control its pyrene dynamics.
Concrete scheme of the present invention is as follows:
As shown in Figure 1, scissor-shaped core splitting knife of the present invention, by knife handle (1) and it is located at the hook-shaped of knife handle one end and splits core
Cutter hub (2) composition, cutter hub are made of two head ends in the component (3) of hook solid, and (5) are blade on the inside of crotch, to crystalline substance of riving
Shape body core.
It has been observed that two cutter hubs (7) (8) are combined in scissor-shaped, and are realized by stirring the fastener (4) being arranged on knife handle
The scissor on core splitting knife head separates.
It has been observed that two core splitting knife heads are in hook solid, the inside (5) of crotch is blade, and crotch least significant end (6) is blunt circle
Type structure forms a piece of blade when two panels hook type blade is combined.
It has been observed that the knife handle of core splitting knife scissor-shaped is embedded in pipe handle (1), wherein a knife handle (7) is fixed in the handle,
There are finger fastener (4) on another knife handle (8), is exposed to outside handle, to control the folding of cutter hub head end.Two cutter hub closures
When, fastener (4) partial embedding is in the small window (9) of knife handle.
It has been observed that the cutter hub of core splitting knife forms obtuse angle bending (10) at pleasing to the eye place, pleasing to the eye place folding distance (including itself
Thickness) it is no more than 3.0 millimeters, the maximum open distance of two cutter hub head ends (3) is no more than 4.0 millimeters, the blade on crotch head
(5) highly it is no more than 3.0 millimeters.
Effect of the invention, which is that the core splitting knife can not only be stablized by the cutter head of trans- crotch-shaped, holds crystal nuclear, but also can
Effectively to control the folding dynamics of cutter head by scissors control, achievees the purpose that voluntarily to separate crystal nuclear in art, be split to improve
The safety and efficiency of core.
Detailed description of the invention
Fig. 1 is the positive structure schematic of the trans- scissor core splitting knife of embodiment
Fig. 2 is the opening and closing state side schematic view of the trans- scissor core splitting knife of embodiment
Specific embodiment
As shown in Figure 1, trans- scissor core splitting knife of the present invention, by knife handle (1) and it is located at the hook-shaped of knife handle one end and splits
Core cutter hub (2) composition, core splitting knife head are in trans- hook solid, and the inside of crotch is blade (5), and crotch front end is blunt circle type knot
Structure (6) forms a piece of blade when two panels hook type blade is combined.Two cutter hubs are combined in scissor-shaped, and by stirring
The fastener (4) being arranged on knife handle realizes the scissor separation on core splitting knife head.The cutter hub of core splitting knife forms an obtuse angle at pleasing to the eye place
It bends (10), pleasing to the eye place's folding distance (including thickness itself) is no more than 3.0 millimeters, the maximum open of two cutter hub head ends (3)
Distance is no more than 4.0 millimeters, and the blade (5) on crotch head is highly no more than 3.0 millimeters.
As shown in Fig. 2, core splitting knife passes through cornea in closed state or Gong Yuan main notch in angle protrudes into camera oculi anterior, hold brilliant
After body core, to core pushed, reaches core center or when close to core center, the scissors fastener stirred on knife handle opens core splitting knife head
End, is about to crystal nuclear certainly and is divided into two.After turning core, repeat similar to splitting core operation to divide core block two to be four.After core operation is split in end,
Core splitting knife exits intraocularly in closed state.
