Description
Technical Field
The utility model relates to the field of biological experiment tools, in particular to a simple and easy-to-use small blade for library construction.
Background
The gene library refers to a clone population containing the whole DNA sequence of an organism, and because of the numerous genes in the organism, the required target gene sequence is difficult to find, and after the gene library is constructed, the target gene sequence can be obtained through continuous replication, and the sequencing efficiency can be improved.
In the process of constructing a gene library, when a researcher wants to acquire the genome of a tissue at a specific part of an organism, the tissue at the specific part needs to be cut, and then the genome is sequenced. In the cutting process, a scalpel is usually used as a cutting tool, and the cutting tool is not a disposable device, so that the scalpel can be repeatedly used through disinfection and cleaning, most of the existing scalpel is in a plane shape, excessive tissues are easily cut when the scalpel is used, and due to the experiment requirement, a tissue block with a certain size can be needed to be cut, but in the prior art, the scalpel can only be used for cutting after the size is measured by a measuring tool, the process is multiple, and the use of an experimenter is inconvenient.
Disclosure of Invention
In order to solve the technical problems, the utility model discloses a simple and easy-to-use small blade for library construction, and the technical scheme of the utility model is implemented as follows:
a simple and easy-to-use knife blade for library construction, comprising: the cutting part, the cutter handle trepanning and the scale marks;
wherein,,
the cutting part comprises a first cutting part and a second cutting part;
the first cutting part and the second cutting part are integrated;
one side of the first cutting part is bent inwards, and the other side of the first cutting part is bent outwards to form an inwards concave arc;
the top of the first cutting part is a tip;
the second cutting part is a conical blade;
the cutter handle trepanning is arranged between the first cutting part and the second cutting part;
the scale mark is arranged on one side of the second cutting part.
Preferably, the length of the second cutting part is 2-4 cm.
Preferably, the first cutting part and the second cutting part are made of medical stainless steel.
Preferably, the length of the concave blade of the first cutting part is 2-3 cm.
By implementing the technical scheme of the utility model, the technical problem that excessive tissues are easily resected when the tissue cutting device is used in the prior art can be solved; by implementing the technical scheme of the utility model, the complete cutting can be realized by adopting the mode of adopting the first cutting part with the concave arc shape and the second cutting part with the conical blade and arranging the scale marks on the second cutting part, the tissues at other parts can not be excessively cut, and the tissue blocks with certain size can be cut through the second cutting part.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples
In a specific embodiment, as shown in FIG. 1, a simple and easy-to-use knife blade for library construction, comprising: the cutting part 1, the cutter handle sleeve hole 2 and the scale mark 3, wherein the cutting part 1 comprises a first cutting part 1-1 and a second cutting part 1-2, and the first cutting part 1-1 and the second cutting part 1-2 are integrated; the other side of the first cutting part 1-1 is bent inwards, the other side is bent outwards to form a concave arc-shaped double-edge blade, and when cutting, one surface bent outwards is used as a main cutting surface in most cases, and because the cutting surface is bent, the cutting is not performed in a moment like a plane-shaped blade in the whole, but is performed slowly, the angle and the used position can be adjusted when cutting, excessive tissues are prevented from being cut, the tip at the top of the first cutting part 1-1 is used, the cutting work between narrow tissues can be realized, and the middle part of the first cutting part 1-1 is used, so that the wide-range cutting work can be realized. Because the first cutting part 1-1 is a double-edged blade, and one inwards bent surface of the first cutting part 1-1 forms a concave arc line, when the blade works, the cutting work of the two surfaces can be completed without turning the blade, and the use is more convenient.
The second cutting part 1-2 is a conical blade, and when the second cutting part 1-2 is used, the blade needs to be removed from an external cutter handle, and the positions of the first cutting part 1-1 and the second cutting part 1-2 need to be adjusted. A graduation mark 3 is provided at one side of the second cutting part 1-2, and when it is required to cut a tissue mass of a certain size using the second cutting part 1-2, it is possible to observe whether the cut tissue mass reaches a size desired by an experimenter through the graduation mark 3.
The tool shank trepanning 2 is arranged between the first cutting part 1-1 and the second cutting part 1-2 and is used for connecting an external tool shank.
In a preferred embodiment, the length of the second cutting part 1-2 is 2-4 cm, and when the cutter handle is mounted, the second cutting part 1-2 is not required to be too long to influence normal use.
In a preferred embodiment, the first cutting portion 1-1 and the second cutting portion 1-2 are made of medical stainless steel, and have excellent corrosion resistance in biological tissues as compared with industrial structural stainless steel.
In a preferred embodiment, the length of the concave blade of the first cutting portion 1-1 is set to be between 2 and 3cm in order to prevent the blade of the first cutting portion 1-1 from damaging the tissue in the living body at the time of cutting.
It should be noted that the above-mentioned embodiments are only preferred embodiments of the present utility model, and are not intended to limit the present utility model, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
