Abstract
The invention discloses a fixed damage model cutter for the liver of a rat. The fixed damage model cutter comprises an annular bottom plate and an annular knife arranged in the center of the annular bottom plate and extending out of the annular bottom plate, wherein air holes used for air exhaust and steel wires used for cutting during rotation are formed on the annular bottom plate. According to the fixed damage model cutter for the liver of the rat, few tools are used, manual damage except a research object is reduced, the liver tissue with a fixed size can be cut, system errors are small, the number of experimental animals is further reduced, the cutter is convenient to operate, the operation time is shortened, and experiment and comparison results are more accurate.
Description
Technical field
The present invention relates to technical field of medical instruments, particularly relate to a kind of rats'liver and fix damage model cutting
Device.
Background technology
In order to make the contrast between different hemostasia products and scheme more meaningful, in experiment, standing putting fixes research
Object, fixed size damage model, for the manufacture of rule bleeding lesions model in more document, often make
Instrument be shears and scalpel, but between the damage model that produces of this type of method, difference is relatively big, no
Accurate evaluation can be used for.During such as Davidson, B R et al. tested in 2000, tear manufacture with hands dynamic
Thing hepar damnification, this type of way is serious to tissue injury beyond hepar damnification, and precision is not good enough, or impact is real
Test result.Even if mentioning in an experiment at nineteen eighty-three Heinz Jakob et al. and making a call to one on rats'liver lobus sinister
The hole of individual diameter 1cm thickness 2mm, but, concrete steps and explain in detail the most not mentioned.Different hemostasis
In product and project plan comparison, the mensuration of its bleeding stopping period is required the highest, excessively complicated damage instrument and
Method is unfavorable for mensuration and the record of bleeding stopping period, if the operating time is long, hemostasis can cause damage not in time
Injury blood is excessive, thus forms adhesion, if to different hemostasia products and side after experimental design certain time limit
Case carries out being adhered assessment, then stopping blooding the adhesion caused not in time owing to the operating time is long can be to experimental result
Cause the biggest impact.Such as Davidson, B R et al. in 2000 to a kind of tencel protein blocking
In the research of agent, manufacture the wedge shape damage of liver, after causing damage, needed to be relatively large in diameter tangent plane
Big blood vessel ligatures, secondly the area of tangent plane to be measured and take off the weight of tissue, complex steps,
Record pole inaccuracy to bleeding stopping period.
Summary of the invention
The technical problem to be solved is: provide a kind of rats'liver to fix damage model sickle,
Can cut the liver spleen tissue of fixed size, systematic error is little.
For solving above-mentioned technical problem, the technical scheme is that
A kind of rats'liver is provided to fix damage model sickle, including: annular bottom plate, and it is arranged on described
The endless knife of this annular bottom plate is also stretched out in annular bottom plate center；Be provided with on described annular bottom plate for
The pore of aerofluxus and in time rotating the steel wire of cutting.
Wherein, in above-mentioned rats'liver fixes damage model sickle, described steel wire is arranged on institute across
State on the end face of annular bottom plate, and described endless knife is divided into quarter.
Wherein, in above-mentioned rats'liver fixes damage model sickle, described pore is two, two institutes
State pore to lay respectively in two relative equal portions.
Wherein, in above-mentioned rats'liver fixes damage model sickle, the ring edge of described endless knife is equal
Have blade.
Wherein, in above-mentioned rats'liver fixes damage model sickle, described annular bottom plate is away from described ring
One end of shape cutter connects handle.
Have employed technique scheme, the invention have the benefit that
Compared with prior art, a kind of rats'liver of the present invention fixes damage model sickle, uses instrument
Few, decrease artificial to the damage beyond object of study, and the hepatic tissue of fixed size can be cut,
Systematic error is little, and then decreases the quantity of laboratory animal, the most easy to operate, shortens the operating time,
Make experiment and comparative result the most accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation that the rats'liver of the embodiment of the present invention fixes damage model sickle；
In figure: 1 is annular bottom plate；2 is endless knife；3 is pore；4 is steel wire；5 is handle.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is described in further detail.
Following example are used for illustrating the present invention, but can not be used for limiting the scope of the present invention.
Include as it is shown in figure 1, the rats'liver of the embodiment of the present invention fixes damage model sickle: the annular end
Plate 1, and be arranged on annular bottom plate 1 center and stretch out the endless knife 2 of this annular bottom plate 1.Annular
The ring edge of cutter 2 all has blade and thins, and facilitates circumgyration incision, annular bottom plate 1 is provided with use
In aerofluxus pore 3 and for rotate time cutting steel wire 4.The work of 1 fixing depth of cut of annular bottom plate
With, can prevent from, owing to operator overexerts, making depth of cut the deepest, thus cause deep damage,
This annular bottom plate 1 has handle 5 away from one end connection of endless knife 2 so that easy to operate.Pore 3
Be disposed to be exhausted in cutting process, in case intrinsic pressure excessive cause cutting difficulty.
In the present embodiment, steel wire 4 is arranged on the end face of annular bottom plate 1 across, and by endless knife 2
Being divided into quarter, pore 3 is two, and two pores 3 lay respectively in two relative equal portions.
During use, selecting a certain region of liver, left-hand finger fixes this region, and the right hand holds handle 5, is placed in
Liver surface, determines position, exerts a force downwards, is close to liver surface with annular bottom plate 1, multi-turn rotation,
Resection organization departs from bottom surface to utilize steel wire 4 and endless knife 2 to guarantee, removes sickle afterwards, uses tweezer
Son removes tangent plane residue tissue.Hemorrhage Model manufactures complete.
As it has been described above, a kind of rats'liver of the present invention fixes damage model sickle, use instrument few, subtract
Having lacked artificial to the damage beyond object of study, and can cut the hepatic tissue of fixed size, system is by mistake
Difference is little, and then decreases the quantity of laboratory animal, the most easy to operate, shortens the operating time so that real
Test the most accurate with comparative result.
The above-mentioned description to embodiment is to be understood that for ease of those skilled in the art and answer
Use the present invention.These embodiments obviously easily can be made various repairing by person skilled in the art
Change, and General Principle described herein is applied in other embodiments without through performing creative labour.
Therefore, the invention is not restricted to embodiment here, those skilled in the art are according to the announcement of the present invention, right
Improvement and the amendment made in the present invention all should be within protection scope of the present invention.
