Description
Technical field
This utility model relates to technical field of medical instruments, and particularly a kind of full femtosecond laser ophthalmologic operation is with inter-lamination of cornea lens separator.
Background technology
Full femtosecond laser operation is the up-to-date near-sighted ophthalmologic operation of treatment.In clinical, need under high magnified glass, the eyes inter-lamination of cornea be separated.There is significant impact in the quality of the instrument of the contact cornea that uses to the risk of operation.The inter-lamination of cornea lens separator of prior art is generally single hook-shaped detaching hook, is the uniform flat sheet-like of circle obtuse or width.The inter-lamination of cornea lens separator of circle obtuse and cornea to contact face amount less, tear or break cornea easily, cause malpractice.Because ophthalmologic operation need carry out under high magnified glass, the inter-lamination of cornea lens separator of flat sheet-like blocks doctor's sight line easily, the same risk that causes performing the operation and make mistakes that exists easily.
The utility model content
The purpose of this utility model is in order to solve the defective that above-mentioned existing inter-lamination of cornea lens separator exists, to provide a kind of and can improve the ophthalmologic operation safety coefficient, and full femtosecond laser operation easy to use is with inter-lamination of cornea lens separator.
In order to realize the foregoing invention purpose, the technical solution of this utility model is following:
The full femtosecond laser operation of this utility model comprises detaching hook handle, detaching hook front portion and detaching hook rear portion with inter-lamination of cornea lens separator.It is coaxial fixing that detaching hook handle one end is inserted at the detaching hook rear portion.The bending angle is 90 °～130 ° between detaching hook front portion and the detaching hook rear portion.The detaching hook front portion is flat elongate, and end is an operate portions.Directly separate at inter-lamination of cornea when operate portions is used to perform the operation, width is bigger, is flat soup ladle shape, and all the corner angle slyness of all polishing can obviously improve operation safety when operation.
Said detaching hook front portion and detaching hook rear portion are stainless steel part.Stainless steel part has enough rigidity and toughness, when pullling cornea, can not be out of shape, can aged deterioration when high-temperature sterilization, and long storage time can not produce rusty stain.Don't use the structure of electroplating surface, peel off, cause malpractice easily because of high-temperature sterilization is easy to generate electrodeposited coating.
According to the principle of being convenient to operate, obtain empirical value, confirm that said detaching hook width range anterior and the detaching hook rear portion is 0.3～1.0 millimeter; The width range of said operate portions is 0.5～1.2 millimeter, and length range is 1.0～1.8 millimeters; The forward thickness range of said detaching hook is 0.2～0.5 millimeter, and length range is 10～15 millimeters.
Preferably, said detaching hook width anterior and the detaching hook rear portion is 0.5 millimeter; The width of said operate portions is 1.1 millimeters, and length is 1.5 millimeters; The forward thickness of said detaching hook is 0.3 millimeter, and length is 12 millimeters.
Preferably, the bending angle is 120 ° between said detaching hook front portion and the detaching hook rear portion.
The other end of said detaching hook handle is provided with the needle-like detaching hook of circle obtuse.This end also can be equipped with other instruments commonly used in the operation, and the doctor can change instrument easily in operation.
The surface of said detaching hook handle is provided with annular knurl, so that increase the frictional force that contacts with hand.The detaching hook handle can be made by lightweight rustless metals such as titanium alloy or aluminium alloys, and the surface is provided with annular knurl can increase the frictional force that contacts with hand, and instrument falls in avoiding performing the operation.
The surface roughness at said detaching hook front portion and detaching hook rear portion is less than 0.2.Because of full femtosecond laser operation contacts fragile, meticulous human organs such as eyes cornea with inter-lamination of cornea lens separator; Full femtosecond laser operation need possess very high surface accuracy with inter-lamination of cornea lens separator; In order to avoid the damage organ avoids the dirty of tool surfaces to pollute organ.
The beneficial effect of this utility model is: 1, the anterior terminal operate portions of detaching hook is flat soup ladle shape, whole corner angle slynesses of all polishing, and width is bigger, and the pressure of contact cornea is less, can ensure that cornea can not break when tearing.2, the detaching hook front portion is flat elongate, under high magnified glass, also can not hinder doctor's sight line, has guaranteed the safety of operation.3, bending between detaching hook front portion and the detaching hook rear portion, the principle of ergonomic increases convenience and comfort level that the doctor uses.
Description of drawings
Fig. 1 is the structural representation of the full femtosecond laser operation of this utility model with inter-lamination of cornea lens separator;
Fig. 2 is the forward local amplification front elevation of detaching hook.
Among the figure: 01, detaching hook hands handle; 02, detaching hook rear portion; 03, detaching hook is anterior; 31, operate portions; 04, needle-like detaching hook.
The specific embodiment
Below in conjunction with accompanying drawing this utility model preferred embodiment is further specified, be not regarded as restriction this utility model protection domain.This utility model inter-lamination of cornea lens separator also is applicable to the ophthalmologic operation of all operations under magnifier.
Like Fig. 1, shown in Figure 2, the full femtosecond laser operation of this utility model comprises detaching hook handle 01, detaching hook anterior 03 and detaching hook rear portion 02 with inter-lamination of cornea lens separator.The surface of detaching hook handle 01 is provided with annular knurl.It is coaxial fixing that detaching hook handle 01 1 ends are inserted at detaching hook rear portion 02.The bending angle is 120 ° between detaching hook anterior 03 and the detaching hook rear portion 02, is stainless steel part, and surface roughness is less than 0.15.Detaching hook anterior 03 is flat elongate, and end is an operate portions 31.Directly separate at inter-lamination of cornea when operate portions 31 is used to perform the operation, width is bigger, is flat soup ladle shape, all the corner angle slyness of all polishing.The width at said detaching hook anterior 03 and detaching hook rear portion 02 is 0.5 millimeter; The width of said operate portions 31 is 1.1 millimeters, and length is 1.5 millimeters; The thickness of said detaching hook anterior 03 is 0.3 millimeter, and length is 12 millimeters.The other end of detaching hook handle 01 is provided with the needle-like detaching hook 04 of circle obtuse.This end also can be equipped with other instruments commonly used in the operation, and the doctor can change instrument easily in operation.
The full femtosecond laser operation of this utility model with the operation principle of inter-lamination of cornea lens separator is: during ophthalmologic operation, the doctor holds detaching hook handle 01 under high magnified glass, and operate portions 31 directly contacts the eyes cornea.The doctor makes corresponding diagnosis and treatment as required.The safety that the full femtosecond laser operation of this utility model has improved operation on cornea greatly with inter-lamination of cornea lens separator.
