Description

Immersion type multi-value regulation and control in-vitro eyeball fixator
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of immersion type multi-value regulation and control in-vitro eyeball fixator, can be used for micro-imaging or other accurate operations of in-vitro eyeball sample.
Background technology
In ophthalmology basic research and clinical care, usually need careful observation and dissect the eyeball of a large amount of animal, the eyeball tissue therefore winning all kinds of toy carries out in vitro micro-imaging, is the requisite step of ophthalmology diagnosis research field.
But eyeball has spherical, soft wet and slippery physiological feature, and the eyeball shape size difference of different animals is comparatively large, and these factors cause carrying out effective fixing very difficulty to eyeball sample in imaging experiment.In order to ensure the reproducibility of imaging results, and reducing the change to its morphological characteristic as far as possible, needing a kind of convenient reliable eyeball fixing means, the position stability of eyeball sample can be remained in imaging process.Meanwhile, to clear observation and the accurate operation of eyeball sample, be unable to do without and high-resolution micro-imaging is carried out to it.High-resolution optical and photoacoustic microscope all need to adopt immersion type object lens, therefore sample must be placed in water environment.And imaging and operation technique need location, visual field and the image acquisition of long period usually, so be eyeball tissue supply normal saline in time, can ensure the stable of sample morphology structure, avoid the irreversible breaking that extraneous dry environment causes.
Whether adjustable according to size, existing in-vitro eyeball fixator can be divided into two classes: a class realizes the fixing of eyeball sample by the combination of two or more parts, but do not possess adjustability; Another kind of is by the object clamping eyeball sample in same level dimension adjustable, is applicable to the eyeball sample of different size.Such as, Chinese patent application Authorization Notice No. is CN202568734U, and the patent that name is called " a kind of in-vitro eyeball fixator ", discloses a kind of in-vitro eyeball fixator, and it is covered by a threaded pressure and be with the pedestal of stud to screw up and fixes eyeball.But the pressure cover of this geomery can only fix the eyeball sample of specific size.In addition, the eyeball be placed in pressure cover limits the flexible adjustment at position, space, adds the difficulty of accurate imaging.Chinese patent application application publication number is CN103310681A, and the patent application that name is called " in-vitro eyeball fixator ", provides a kind of in-vitro eyeball fixator, fixes eyeball by hemispherical groove and four fixing cards.But it only can fix the eyeball of specific size, and easily destroy the anatomical structure of eyeball, limit it in accurate imaging and the application in operating.Only be suitable for the shortcoming of fixing specific large microphthalmia to overcome traditional non-adjustable in-vitro eyeball fixture, researcher has invented adjustable in-vitro eyeball fixator.In-vitro eyeball fixator that these are adjustable mainly passes through the size of alignment jig in same level, to be applicable to the eyeball sample clamping different size.Such as, Chinese patent application mandate publication number is CN203220456U, name is called the patent of " Pop-up eyeball fixture ", disclose a kind of Pop-up eyeball fixture, it fixes eyeball sample by annulus lock tube, but this device only can regulate the position of eyeball sample in the horizontal, the accurate manipulation of eyeball sample lengthwise position cannot be realized.In addition, only clamping scheme in the horizontal easily causes eyeball landing, and reliability is poor.And existing adjustable in-vitro eyeball fixator is all only applicable to on-liquid environment.
