The super newborn crystal nucleus ripper of one hand ophthalmology described in the utility model, the advantage is that, the blade surrounded entirely can be square
Just patient utilizes one-handed performance, i.e., alternative implementation expanding or clipping two kinds split kernel mode.Blade of same size exists
Implement when dilatancy splits core more easily grasp dynamics, blank will not occur after being inserted into core and walk journey.Fixed blade protrusion
Cutter head can when insertion stress first, exert a force not against movable blades, stability is higher.Discoid cutter head can be
Prevent movable blades from slipping away when splitting core, art safety is applied in raising.The finger ring rotatably connected can provide the movement more increased
Dimension keeps one-handed performance more flexible.The setting of first acupressure probe can assist patient to have more when adjusting movable blades
More stress points improves stability.After second acupressure probe combines the first acupressure probe, stress point is further increased, stability also phase
It is due for promotion.

Specific embodiment
As shown in Figure 1-3, the one hand super newborn crystal nucleus ripper of ophthalmology described in the utility model includes sleeve 10 and is arranged in
Drive rod 33 in sleeve 10.Guide pipe 11 is extended in described 10 one end of sleeve, and the other end is equipped with connecting rod 31 and finger ring 32.It is described
31 one end of connecting rod extend into one end of connection drive rod 33 in sleeve 10,31 other end of connecting rod extends to connect outside sleeve 10 and refer to
Ring 32.The drive rod 33 extends guide pipe 11 far from the other end of connecting rod 31, and is equipped with the movable blades of right-angle steering
22.The guide pipe 11 extends the fixed blade 21 parallel with movable blades 22 in the extending direction of drive rod 33.It is described
Fixed blade 21 and movable blades 22 edge be equipped with continuous blade.
The fixed blade 21 and 22 blade of movable blades is of same size.21 cutter head of fixed blade is pointed structures, and
21 cutter head of fixed blade protrudes from 22 cutter head of movable blades.22 cutter head of movable blades is disc-shaped structure, and disk diameter is greater than knife
Body width.The connecting rod 31 and finger ring 32 is rotary connection.The sleeve 10 is equipped with diameter in the end close to finger ring 32
To the first acupressure probe 12 of extension.The sleeve 10 is equipped with parallel with the first acupressure probe 12 the in the end close to finger ring 32
Two acupressure probes 14 are equipped with the finger groove 13 for accommodating finger between first acupressure probe 12 and the second acupressure probe 14.
The mode of operation and working principle of the super newborn crystal nucleus ripper of one hand ophthalmology described in the utility model are as follows, and patient will
Thumb is inserted into finger ring 32, and middle finger and index finger are inserted into the finger groove 13 of 10 two sides of sleeve respectively, adjusts thumb using rotary structure
With the lateral position of other component.
Larger for core diameter, when needing to implement expanding to split core, the lengthwise position of adjustment finger ring 32 makes fixed blade
21 and movable blades 22 be overlapped, then by fixed blade 21 it is sharp cutter head alignment core be pierced into.With the first acupressure probe 12 and second
Acupressure probe 14 is stress support, and press or pull back finger ring 32, is moved away from fixed blade 21 and movable blades 22, due to fixation
Blade 21 and movable blades 22 are designed with the blade surrounded entirely, can specific location according to core and state flexible choice force side
To.Under the discoid cutter head limit of movable blades 22, core is not easy to slide, and operates more convenient.Expanding splits core and is suitble to ruler
Very little biggish core uses, but disposably can not completely split as both ends, can at least can proceed at this time there are fraction connection position
It is clipping to split core operation.
It is smaller for core size, or implemented after expanding splits core, it can implement and clipping split core.Adjust finger ring 32
Fore-and-aft distance, make the relative gap of fixed blade 21 and movable blades 22 be slightly larger than position to be split length, by fixed blade
21 and movable blades 22 be inserted into and be located at part two sides to be split, pressing or retract finger ring 32 makes fixed blade 21 and movable blades 22
Close to movement and clamp corresponding position of riving.
It finally extracts fixed blade 21 and core operation is split in the completion of movable blades 22.
By the super newborn crystal nucleus ripper of singlehanded ophthalmology described in the utility model, various sizes more flexible can be handled
Core, and can the modus operandi implemented of more flexible selection, reduce deposit and the replacement of device, the art time is applied in saving.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideas
The corresponding change of kind and deformation, and all these changes and deformation all should belong to the guarantor of the utility model claims
Within the scope of shield.
