Description

A kind of mouse in-vitro eyeball materials jaw type clamper

Technical field

The utility model belongs to medical experiment apparatus technical field, more particularly to a kind of mouse in-vitro eyeball materials jaw type Clamper.

Background technology

In ophthalmology Basic Experiment Study, widely used mouse is frequently necessary to implement eye to mouse as experimental subjects Ball is quickly won, and then carries out separation materials to the tissue of in-vitro eyeball.At present, experimenter's progress eyeball of mouse is quickly won During work, most commonly used apparatus is tweezers, can be put into after by tweezers, eyeball of mouse is quickly won in liquid environment And under microscope, but there is the characteristics of small volume, wet and slippery and fragile in in-vitro eyeball, be difficult to clamp in liquid environment and fix, The tissue separation for wanting accurately to complete eyeball of mouse is drawn materials, and its difficulty also increases considerably, and can also increase experimental error, so as to Reduce the success rate of experiment.Although someone specially devises in-vitro eyeball fixator, it has higher cost and more complicated Structure, and eyeball size and experimental implementation angle are had higher requirements, are also not easy to make under the microscope and in liquid environment With.In addition, the use of in-vitro eyeball fixator not only adds laboratory operating procedures, and when virtually also increasing experiment Between, the quick fixation won with in-vitro eyeball of particularly eyeball of mouse needs to use two sets of apparatuses that (tweezers and in-vitro eyeball are consolidated Determine device), the operating efficiency of integral experiment will necessarily be reduced.

Therefore, it is necessary to design a kind of brand-new experiment apparatus, it should be provided simultaneously with eyeball and quickly win and in-vitro eyeball Fixed ability, and have the advantages of simple in construction and cost is low concurrently.

Utility model content

The problem of existing for prior art, the utility model provide a kind of mouse in-vitro eyeball materials jaw type clamper, It is provided simultaneously with eyeball and quickly wins the ability fixed with in-vitro eyeball, and have the advantages of simple in construction and cost is low concurrently, conveniently exists Used under microscope and in liquid environment, effectively improve the operating efficiency and success rate of experiment.

To achieve these goals, the utility model adopts the following technical scheme that：A kind of mouse in-vitro eyeball materials jaw type Clamper, including clamp handle, the pincers cheek and jaw, clamp handle cross-articulation at the pincers cheek, are provided with locking teeth button between clamp handle, Clamp handle end is provided with dactylostyle；Be respectively arranged with left semi-clamp spoon and right semi-clamp spoon in the jaw end, and left semi-clamp spoon with Right semi-clamp spoon closes to form complete pincers spoon, and the complete spoon that clamps is spherical structure；In the left semi-clamp spoon and the interface of right semi-clamp spoon Docking sawtooth is provided with, and docks sawtooth and uses without sword circle obtuse broached-tooth design.

The left semi-clamp spoon and right semi-clamp spoon have the rear elevation angle relative to clamp handle, and the rear elevation angle is 30 °~45 °.

The spherical radius that the complete pincers spoon formed is closed by the left semi-clamp spoon and right semi-clamp spoon is 4.5mm~5mm, and complete The hollow depth of whole pincers spoon is 2mm~2.5mm.

The length of the clamp handle is 50mm~60mm.

The beneficial effects of the utility model：

Mouse in-vitro eyeball of the present utility model is drawn materials jaw type clamper, quickly won particular for eyeball of mouse and from The tissue separation materials of body eyeball are designed, and with reference to mice eye anatomical structure feature, have been firstly introduced the pincers of spherical structure Spoon, and make pincers spoon that there is certain rear elevation angle relative to clamp handle, eyeball of mouse of being so more convenient for is won；Meanwhile in two halves Clamp and be also provided with docking sawtooth on the interface of spoon, and dock sawtooth and employ no sword circle obtuse broached-tooth design, not only can be with Accidental injury of the pincers spoon to eyeball of mouse side wall is reduced, folder of the pincers spoon to internal rectus muscle, musculus rectus lateralis and optic nerve can also be increased Holding force.In addition, after eyeball of mouse is quickly won, in-vitro eyeball can be by direct fixed clamp in pincers spoon, thus synchronously realizes Eyeball of mouse is won and fixed, and effectively increases the operating efficiency of experiment.Further, the utility model also have it is simple in construction and The advantages of cost is low, and conveniently use under the microscope and in liquid environment, and the success rate of experiment can be effectively improved.

Embodiment

The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.

As shown in Figure 1, 2, a kind of mouse in-vitro eyeball materials jaw type clamper, including clamp handle 1, the pincers cheek 2 and jaw 3, institute The cross-articulation at the pincers cheek 2 of clamp handle 1 is stated, locking teeth button 4 is provided between clamp handle 1, the end of clamp handle 1 is provided with dactylostyle 5； The end of jaw 3 is respectively arranged with left semi-clamp spoon 6 and right semi-clamp spoon 7, and left semi-clamp spoon 6 has been formed with right semi-clamp spoon 7 closure Whole pincers spoon, the complete spoon that clamps is spherical structure；Docking sawtooth 8 is provided with the interface of the left semi-clamp spoon 6 and right semi-clamp spoon 7, And docking sawtooth 8 is using without sword circle obtuse broached-tooth design.

The left semi-clamp spoon 6 and right semi-clamp spoon 7 have the rear elevation angle relative to clamp handle 1, and the rear elevation angle is 30 °~45 °.

The spherical radius that the complete pincers spoon formed is closed by the left semi-clamp spoon 6 and right semi-clamp spoon 7 is 4.5mm~5mm, and The hollow depth of complete pincers spoon is 2mm~2.5mm.

The length of the clamp handle 1 is 50mm~60mm.

Illustrate first use process of the present utility model below in conjunction with the accompanying drawings：

During original state, left semi-clamp spoon 6 and right semi-clamp spoon 7 are open configuration, and thumb and forefinger hold two dactylostyles respectively 5, left semi-clamp spoon 6 and right semi-clamp spoon 7 are first respectively placed in eyelid medial canthal and the outer canthus portion of death assay mouse, then firmly push Clamp handle 1, make the gradual bulging of eyeball of mouse, until the complete bulging of eyeball of mouse and between left semi-clamp spoon 6 and right semi-clamp spoon 7 Afterwards, thumb and forefinger are firmly close so that left semi-clamp spoon 6 and right semi-clamp spoon 7 gradually close, and then by internal rectus muscle, musculus rectus lateralis with And optic nerve clamps, while the realization of locking teeth button 4 fastens, last vertically outwards to exert oneself, and eyeball of mouse is in vitro.Locking Under the button force action of tooth button 4, what eyeball of mouse was stablized is clamped between left semi-clamp spoon 6 and right semi-clamp spoon 7, can incite somebody to action afterwards The clamper for being clamped with eyeball of mouse is moved on under microscope, and eyeball of mouse is immersed in liquid environment and carries out follow-up tissue point From materials, and eyeball of mouse now is stably fixed in clamper, be ensure that the precision of tissue separation materials, is reduced The operation difficulty of tissue separation materials.

Scheme in embodiment simultaneously is not used to limit scope of patent protection of the present utility model, all without departing from the utility model Carried out by equivalence enforcement or change, be both contained in the scope of the claims of this case.
