The eyeball fixing device is formed by buckling two lock buckles, the animal eyeball samples can be conveniently and reliably fixed, the use performance is good, the experiment efficiency can be favorably improved, the experiment operation difficulty can be reduced, meanwhile, the fixing device can be repeatedly used, the material waste is avoided, and the experiment cost is favorably reduced.

Description

Eyeball fixture

Technical field

This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of eyeball fixture.

Background technology

Along with modern medicine, the development of technology such as biology, zoopery is widely used in the various researchs, especially the operations research of ophthalmology common disease, general all is experiment sample with the animal eyeball, wherein with the various ophthalmology experiments of rat eye as experiment sample, account for more than 65% of animal ophthalmology experiment, after taking the rat eye sample, rat eye is fixed, experiment then undergos surgery, check feasibility and the therapeutic effect thereof of operation method by the rehabilitation situation of observing rat eye, in the prior art be that sample is when doing experiment with the animal eyeball, usually it is fixing to adopt nylon wire that animal eyeball is bundled, and binding nylon wire and knotting operation are inconvenient, waste time and energy; After knotting, nylon wire easily gets loose, and fixing unreliable, and nylon wire easily is infected with dirt, is not easy to clean, and generally do not reuse, and causes the waste of material.

Therefore, for addressing the above problem, need a kind of animal eyeball sample-specific fixture, not only make the convenient fixing, reliable of animal eyeball sample, and can reuse, reduce cost.

The utility model content

In view of this, the purpose of this utility model provides a kind of eyeball fixture, can make things convenient for, reliably the animal eyeball sample be fixed, and serviceability is good, is beneficial to improve conventional efficient, reduction experimental implementation difficulty; This fixture is reusable simultaneously, and no waste of material is beneficial to the reduction experimental cost.

Eyeball fixture of the present utility model comprises snap close I and snap close II; Described snap close I and snap close II can be fastened and connected and form the fixedly annular lock tube of animal eyeball sample.

Further, described snap close I and snap close II are adsorbed fastening mutually by magnetic field force.

Further, described snap close I and snap close II are semicircular arc; The radius of snap close I and snap close II is identical and be not more than the radius that needs fixing animal eyeball sample.

Further, described snap close I and snap close II one end are hinged, and the other end fastens.

Further, the jointed shaft of described snap close I and snap close II is perpendicular to snap close I and plane, snap close II place.

The beneficial effects of the utility model are: eyeball fixture of the present utility model, and adopt two snap closes to fasten and form, can be convenient, reliably the animal eyeball sample is fixed, serviceability is good, is beneficial to improve conventional efficient, reduction experimental implementation difficulty; This fixture is reusable simultaneously, and no waste of material is beneficial to the reduction experimental cost.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further described:

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Fig. 1 is structural representation of the present utility model, and as shown in the figure: the eyeball fixture of present embodiment comprises snap close I 1 and snap close II 2; Described snap close I 1 can be fastened and connected with snap close II 2 and form the fixedly annular lock tube of animal eyeball sample, this annular lock tube can be made as circle also can be made as polygon, and the multiple size that setting is corresponding with different animals eyeball sample is as arranging the rat eye fixture that a kind of size conforms to it for the more rat eye sample of use; The two ends of snap close I 1 can be distinguished snapping with the two ends of snap close II 2 and be connected, and also an end of snap close I 1 and an end of snap close II 2 can be articulated and connected the other end snapping of the other end of snap close I 1 and snap close II 2; The syndeton of snapping can be eye-splice or bonding by magnetic field force, all can realize this utility model purpose; Earlier the animal eyeball sample is positioned in the snap close I 1 during use, then snap close II 2 and snap close I 1 fastening is locked the animal eyeball sample.

In the present embodiment, described snap close I 1 is adsorbed fastening with snap close II 2 mutually by magnetic field force, fixedly installing a Magnet (4,5) respectively by the snapping end in snap close I 1 and snap close II 2 realizes, during use snap close I 1 and snap close II 2 make-ups can be fastened under the magnetic field force effect, simultaneously can produce certain magnetic field absorption affinity, can make things convenient for, reliably the animal eyeball sample be fixed, serviceability is good; This fixture is reusable simultaneously, no waste of material.

In the present embodiment, described snap close I 1 and snap close II 2 are semicircular arc; The radius of snap close I 1 and snap close II 2 is identical and be not more than the radius that needs fixing animal eyeball sample, snap close I 1 and snap close II 2 are made as semicircular arc, and to make snap close I 1 and snap close II 2 fasten the annular lock tube that forms rounded, be complementary with the animal eyeball sample shape, be beneficial to maintenance animal eyeball sample shape after fixing, reduce the crimp to the animal eyeball sample.

In the present embodiment, described snap close I 1 is hinged with snap close II 2 one ends, the other end fastens, snap close I 1 and snap close II 2 are connected as one, structural integrity is good, also can carry out simultaneously spacingly mutually between snap close I 1 and the snap close II 2, during use snap close II 2 be rotated to fasten with snap close I 1 around its jointed shaft 3 and get final product, can improve the quality of fit of snap close I 1 and snap close II 2.

In the present embodiment, the jointed shaft 3 of described snap close I 1 and snap close II 2 is perpendicular to snap close I 1 and plane, snap close II 2 place, and is rational in infrastructure, can form bigger opening, is convenient to the fixing of animal eyeball sample.

Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment this utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
