For the utensil in biological organization sample slice preparation processTechnical field
The present invention relates to a kind of utensils in biological organization sample slice preparation process.
Background technique
It is sliced one kind of (qiepian) slide sample.For the animal vegetable tissue of optical microscopy or electron microscope observationThin slice.Because requiring difference, free-hand section can be carried out with blade, tissue block can also be embedded in paraffin or collodion or with low temperatureFrost, uses microtome.5~10 micro flakes are cut into, for optical microphotograph sem observation.With epoxy resin or methacrylic acid packetThe ultra-thin section of tissue block cutting is buried, thickness is specialized in and observed under an electron microscope at 20~50 nanometer.General teachingAs the slice of the tip of a root, stem is generally called paraffin section.In biology and process of general chemistry teaching, or in experimental study usually, needTeacher or student or the hand-made slice of other experimenters are wanted, is needed at this time by biological organization sample in preparation process processIn be transferred in another liquid from a liquid, sample can be picked up carefully or directly be taken with hand by general experimenterIt takes, it is improper such as to control, and often will appear phenomena such as accidentally biological tissue samples are clipped broken or lost, destroys biological tissueThe integrality of sample, hampers experiment progress, loses sometimes very huge.Currently on the market still without dedicated for being sliced systemThe tool of biological organization sample is shifted during making.
Summary of the invention

Microprocessor, is arranged in the second end of the first or second gripping arm, the microprocessor respectively with it is describedRegulating device is connected with the range sensor, also prestored in the microprocessor biological organization sample slice thickness with it is describedFirst corresponding relationship of the distance between the web shape body of the first and second gripping arms prestores described first in the microprocessorSecond corresponding relationship of the chucking power size that the distance between web shape body of the second gripping arm is provided with the regulating device.
Preferably, in the described utensil in biological organization sample slice preparation process, the web shape body is by settingRouge material is made.
Preferably, in the described utensil in biological organization sample slice preparation process, the regulating device packetScrew and the nut that described screw one end is set are included, the outside of the first or second gripping arm is arranged in the nut, andThe nut is movably bolted on the screw, for adjusting the chucking power of the screw.
Preferably, in the described utensil in biological organization sample slice preparation process, described first and secondGripping arm is pivotally connected to one another in H-type.
Preferably, in the described utensil in biological organization sample slice preparation process, the reset spring isCompressed spring.
Preferably, in the described utensil in biological organization sample slice preparation process, the reset springBoth ends are separately fixed at the inside of the second end of nearly first and second gripping arm.
Preferably, in the described utensil in biological organization sample slice preparation process, the table of the web shape bodyFace is coated with shockproof cushioning layer.
The present invention is include at least the following beneficial effects:
When using this product, the thickness of sample to be moved can be set on the microprocessor first, according to first pairIt should be related to, the distance between web shape body of first and second gripping arm can be set, further according to the second corresponding relationship, micro- placeIt manages device and adjusts regulating device to a certain degree, so that the distance between clamping region can just accommodate sample to be moved, with canIt treats mobile example and suitable chucking power is provided.Also, the clamping region that the present invention is arranged is web shape body, treats mobile examplePackage ability is relatively good, and sample to be moved after not falling out or damaging ensure that the integrality of sample.
Present invention production is simple, and easy to operate, practical value is big.Slice preparation process in, by biological organization sample fromIt is transferred in another liquid in one liquid, protects the integrality of biological organization sample, improve the probability of Success in Experiment.
Further advantage, target and feature of the invention will be partially reflected by the following instructions, and part will also be by thisThe research and practice of invention and be understood by the person skilled in the art.
Detailed description of the invention
Fig. 1 is the structure for the utensil that the present invention is sliced in preparation process in one embodiment for biological organization sampleSchematic diagram.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification textWord can be implemented accordingly.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or moreThe presence or addition of a other elements or combinations thereof.
As shown in Figure 1, the present invention provides a kind of utensil in biological organization sample slice preparation process, feature existsIn, comprising:
