Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, the heterogeneity biological cornea of a kind of improvement
Transfering device.
Background technology
Keratopathy is one of topmost reversibility in the world today, blinding oculopathy, keratopathy
Morbidity is many, and annual China waits that the patient of corneal transplantation probably has ten thousand example more than 30, and this
Numeral is just presenting the trend risen year by year.Corneal transplantation be clinical treatment keratopathy most preferably
Selecting, but China's donor's cornea lacks, according to statistics, each big ophthalmologic hospital of annual China completes
About corneal graft only 7,000 example.The wretched insufficiency of cornea of the same race, promotes people continuous
The new material that can substitute cornea of the same race is found in research, makes a general survey of the research history of artificial cornea,
The glass cornea occurred the most the earliest or the macromolecule cornea being applied to now clinic, suffer from
Such as simple in construction, poor biocompatibility, degradable etc. shortcoming.At present, substantial amounts of research
It is concentrated mainly in acellular cornea stroma materials and this two class of engineered corneal material.But
Generally speaking, up to the present this class of acellular cornea stroma materials is achieved with breakthrough, other
Engineered all also in the theoretic discussion stage.Therefore cell hetero stroma of cornea material is gone to exist
Apparatus to be used in production does not the most improve, and shows according to relevant research data, greatly
Partly the cornea in such research, only produces as clinical research, typically takes Laboratory Production.
Wherein, the pipetting of corneal stroma in process of production, producers use metal under normal circumstances
Tweezers, the operation of metal tweezers is the most convenient, the bad control of power, it is easy to corneal substrate is made
Becoming abrasion thus cause conforming product rate low, metal tweezers are easy to get rusty simultaneously, polluted product.
Utility model content
The technical problems to be solved in the utility model is to provide the heterogeneity biological cornea of a kind of improvement
Transfering device, it is possible to solve the deficiencies in the prior art, low cost, simple for production, simple to operate,
Easily preserve, can repeatedly sterilizing use.
For solving above-mentioned technical problem, technical solution adopted in the utility model is as follows.
The heterogeneity biological cornea transfering device of a kind of improvement, including hemispherical spoon body and handle, hemisphere
Being evenly arranged with several pod apertures in shape spoon body, the surface configuration of handle has screw thread layer, handle
Long 15cm, a diameter of 1cm, a diameter of 1.5cm～5cm of hemispherical spoon body, hemispherical spoon
The degree of depth of body is 0.5cm～2cm.
As preferably, described hemispherical spoon body is provided with mounting groove, bottom mounting groove, passes through bullet
Spring body connects rubber fastener, is provided with and the draw-in groove of handle selectivity clamping in rubber fastener.
As preferably, it is convex that the inner surface of described hemispherical spoon body is evenly arranged with several arcs
The portion of rising, arc convex portion is positioned between adjacent pod apertures, and the outward flange of pod apertures is provided with tiltedly
Face, the edge in arc convex portion is connected with each other with inclined-plane, the surface configuration in arc convex portion have with
The guiding gutter of inclined-plane connection.
What employing technique scheme was brought has the beneficial effects that: this utility model is used for pipetting
Remove cell hetero stroma of cornea, do not have useful metal tweezers to pipette the shortcoming of cornea method, the side of having
Just operate, the advantage such as time saving and energy saving.Through hole is used for filtrate, and screw thread layer can be with increasing friction force.
Handle is by mutually connecting and fixing with rubber fastener, and dismounting is flexible, and handle can be with difference
Angle inserts draw-in groove, thus realizes the connection of handle and hemispherical spoon body different angles.Arc is convex
The portion of rising can avoid cornea to block pod apertures, and the guiding gutter connected with inclined-plane can be with accelerating liquid
Discharge.

Detailed description of the invention
The standardized element used in this utility model all can commercially, shaped piece root
All can carry out customized according to the record with accompanying drawing of description, the concrete connected mode of each part
All use bolt, rivet ripe in prior art, weld, the conventional means such as stickup, at this
No longer describe in detail.
Embodiment 1
With reference to Fig. 1, the heterogeneity biological cornea transfering device of a kind of improvement, including hemispherical spoon body 1
With handle 2, hemispherical spoon body 1 is evenly arranged with several pod apertures 3, the table of handle 2
Face is provided with screw thread layer 4, the long 15cm of handle 2, a diameter of 1cm, hemispherical spoon body 1 straight
Footpath is 1.5cm, and the degree of depth of hemispherical spoon body 1 is 0.5cm.This transfering device is used to pipette
Cell hetero stroma of cornea, does not has useful metal tweezers to pipette the shortcoming of cornea method, has conveniently
Operation, the advantage such as time saving and energy saving.Through hole is used for filtrate, and screw thread layer can be with increasing friction force.
Embodiment 2
With reference to Fig. 2, the present embodiment is the improvement carried out on the basis of embodiment 1, is first
The diameter of hemispherical spoon body 1 changes into 5cm, and the degree of depth of hemispherical spoon body 1 changes 2cm into, its
