Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of in-vitro eyeball fixture.
Background technology
Eyes are one of most important sensory organ of the mankind, are also to allow people experience its sensory organ that is uncomfortable or pathological changes, and eyeball is made up of cornea, iris, crystalline lens and retina etc., its complex structure; When carrying out ophthalmologic operation (as retina transplantation art) or experimentation, usually needing using in-vitro eyeball as operational objectives, because in-vitro eyeball is very round and smooth, not easily fixing, bringing great inconvenience to operation; Up to the present, there is no the device being specifically designed to fixing in-vitro eyeball both at home and abroad, need people when operating and assist help to grip in-vitro eyeball, once coordinate not good, cause the damage of part tissue of eye, cause experimental error or operative failure.
Therefore, just need a kind of in-vitro eyeball fixture, stably can fix in-vitro eyeball, be convenient to ophthalmologist and on in-vitro eyeball, carry out the operation technique of various eye and researcher carries out separation picked-up to various part tissue of eye, improve operating efficiency and operational stability.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of in-vitro eyeball fixture, stably can fix in-vitro eyeball, be convenient to ophthalmologist and on in-vitro eyeball, carry out the operation technique of various eye and researcher carries out separation picked-up to various part tissue of eye, improve operating efficiency and operational stability.
In-vitro eyeball fixture of the present utility model, this device comprises the holder tool for support in-vitro eyeball, and the inner chamber of described holder tool forms eyeball rest area, is provided with the fixture for being fixed on by in-vitro eyeball in eyeball rest area in described holder tool.
Further, described fixture is one in the utricule of spill, and be provided with the cavity volume for containing fluid in described utricule, described utricule can produce with in-vitro eyeball and mutually extrudes and in-vitro eyeball is fixed in eyeball rest area.
Further, the inner chamber of described holder tool is in the spill with in-vitro eyeball mating shapes, and described utricule is covered in the inwall of holder tool.
Further, described utricule is made up of flexible membrane.
Further, described utricule is provided with the filling mouth for fluid-filling, and described filling mouth is connected with cavity volume.
Further, this device also comprises the supporting component for supporting bracket tool, and described supporting component comprises pole and base, and described holder tool, pole and base are connected successively, and described holder tool can the axis of pole be that rotating shaft rotates.
Further, described pole is provided with the resistance rotating part for stoping holder tool to rotate; Described base is provided with clamping mechanism.
The beneficial effects of the utility model: in-vitro eyeball fixture of the present utility model, first in-vitro eyeball is placed on the eyeball rest area of holder tool, in-vitro eyeball is made to be fixed on eyeball rest area by fixture again, stably can fix in-vitro eyeball, be convenient to ophthalmologist and on in-vitro eyeball, carry out the operation technique of various eye and researcher carries out separation picked-up to various part tissue of eye, improve operating efficiency and operational stability; This utility model structure is simple, and easy to use, reliability is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the in-vitro eyeball fixture of the present embodiment, this device comprises the holder tool 1 for support in-vitro eyeball, the inner chamber of described holder tool 1 forms eyeball rest area 2, is provided with the fixture for being fixed on by in-vitro eyeball in eyeball rest area 2 in described holder tool 1; Holder tool 1 profile can be spherical or square, and its top is recessed to form inner chamber downwards, and inner chamber is a part for eyeball rest area 2 (space occupied when namely in-vitro eyeball is placed); Holder tool 1 itself can have certain elasticity, thus fixes in-vitro eyeball by extruding; Preferably, the inner chamber of holder tool 1 in the spill of in-vitro eyeball mating shapes, increase the contact surface of itself and in-vitro eyeball, effectively fix eyeball; Such as, because normal eyeball back/forth diameter is 25.37 ± 1.38mm, transverse diameter is 24.93 ± 1.63mm, and holder tool 1 can be the hollow ball that an anteroposterior diameter and transverse diameter are under the positive spheroid of 28mm 2/3; First in-vitro eyeball is placed on the eyeball rest area 2 of holder tool 1, in-vitro eyeball is made to be fixed on eyeball rest area 2 by fixture again, stably can fix in-vitro eyeball, be convenient to ophthalmologist and on in-vitro eyeball, carry out the operation technique of various eye and researcher carries out separation picked-up to various part tissue of eye, improve operating efficiency and operational stability.
In the present embodiment, described fixture is one in the utricule 3 of spill, be provided with the cavity volume (not shown) for containing fluid in described utricule 3, described utricule 3 can produce with in-vitro eyeball and mutually extrudes and make in-vitro eyeball be fixed in eyeball rest area 2; Because utricule 3 directly contacts with in-vitro eyeball, for avoiding damaging eyeball tissue, utricule 3 is preferably made up of flexible membrane, and namely being enclosed by fexible film can the cystic structures of store fluid; Fluid both can be liquid, also can be gas; Utricule 3 is covered in the inwall of holder tool 1, by pasting or alternate manner realization, makes utricule 3 together recessed with holder tool 1 thus; Because utricule 3 is flexible, by the flowing of fluid in cavity volume, the surface profile of utricule 3 changes to some extent along with the contact of itself and in-vitro eyeball; In the present embodiment, described utricule 3 is provided with the filling mouth (not shown) for fluid-filling, described filling mouth is connected with cavity volume, in cavity volume, the volume of institute's fluid-filling determines the extruding dynamics of utricule 3 pairs of in-vitro eyeballs, this structure is conducive to adjustment extruding dynamics, adapt to the needs of the in-vitro eyeball of different size, improve the versatility of this device.
In the present embodiment, this device also comprises the supporting component for supporting bracket tool 1, and described supporting component comprises pole 4 and base 5, and described holder tool 1, pole 4 and base 5 are connected successively, and described holder tool 1 can the axis of pole 4 be that rotating shaft rotates; Holder tool 1 supports by supporting component, convenient operation; Holder tool 1 is rotatable, is convenient to the angle needing to adjust in-vitro eyeball according to operator; In the present embodiment, described pole 4 is provided with the resistance rotating part 6 for stoping holder tool 1 to rotate; Resistance rotating part 6 can be a nut, now can arrange corresponding external screw thread in pole 4 upper end, and the screw propulsion of nut can form extruding to bottom holder tool 1, thus stops holder tool 1 to rotate; Described base 5 is provided with clamping mechanism 51, and clamping mechanism 51 is clip structure, can be clipped in easily on operation tray or desktop, is convenient to use when operating.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
