Description

Umbilical cord scissors

Technical Field

The utility model relates to a stem cell culture technical field specifically is an umbilical cord scissors.

Background

The umbilical cord stem cells are also called umbilical cord mesenchymal stem cells, generally refer to stem cells extracted from umbilical cord tissues of newborns, have the capacity of differentiating into various tissue cells, and can play roles in immunoregulation, promotion of hematopoietic function recovery, repair of damaged or diseased tissue organs and the like in clinical application.

When extracting stem cells from umbilical cord tissue, umbilical vessels are removed, Fahrenheit glue is peeled off, and then the umbilical vessels are cut into 1mm pieces by scissors³The small blocks are soft and tough, so that the umbilical cord tissues are easy to slide or misplace when being sheared by scissors, the thicknesses of the cut small blocks are different, the small blocks need to be trimmed again, and the shearing process needs a lot of time.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a: the utility model provides an umbilical cord scissors can shear into the fragment of thickness homogeneity with the umbilical cord tissue, improves shearing efficiency to it leads to the inhomogeneous problem of fragment thickness to slide easily when using ordinary scissors to solve.

The utility model adopts the technical scheme as follows:

the utility model provides an umbilical cord scissors, includes handle, cutting edge, the cutting edge includes first cutting edge, second cutting edge, the edge of first cutting edge is equipped with a plurality of antiskid teeth, antiskid teeth are in align to grid on the first cutting edge, be equipped with a plurality of first blades on the first cutting edge, be equipped with a plurality of second blades on the second cutting edge, first blade, second blade are just right.

Preferably, the first blades are arranged equidistantly on the first blade edge and the second blades are arranged equidistantly on the second blade edge.

Preferably, the anti-skid teeth are provided with 2 rows, and the first blade is positioned between the 2 rows of the anti-skid teeth.

Preferably, the first cutting edge and the first blade are arc-shaped, the second blade is semi-elliptical, and the width of the two ends of the second blade is greater than the width of the middle part of the second blade.

Preferably, the height of the anti-slip teeth is greater than the height of the first blade.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

(1) 2 rows of anti-skidding teeth are arranged, the height of each anti-skidding tooth is higher than that of the first blade, the anti-skidding teeth can be inserted into the umbilical cord tissue before the blades during shearing, the umbilical cord tissue is prevented from sliding between the first blade and the second blade, the thicknesses of the sheared fragments are uniform, and secondary trimming is not needed;

(2) the first blade is arc-shaped, so that the anti-skid teeth are also arranged into an arc shape, and the umbilical cord tissue can be bitten by the anti-skid teeth;

(3) the first blade and the second blade are provided with a plurality of blades with equal intervals, a plurality of processed umbilical cord tissues can be obtained by once shearing, and the shearing efficiency is improved by times.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following detailed description of the present invention is made with reference to the accompanying drawings and examples, and it should be understood that the specific examples described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention.

The utility model provides an umbilical cord scissors, including handle, cutting edge, handle and cutting edge are made by the stainless steel, the end connection of handle has 1 becket, the operator grips conveniently, the cutting edge includes first cutting edge 1, second cutting edge 2, the both sides edge of first cutting edge 1 respectively is equipped with 1 row of antiskid tooth 3, antiskid tooth 3 is evenly arranged on first cutting edge 1, be equipped with 4 first blades 4 on the first cutting edge 1, first blade 4 is located between 2 rows of antiskid tooth 3, the height of antiskid tooth 3 is 1mm higher than first blade 4, make antiskid tooth 3 contact with umbilical cord tissue earlier than first blade 4, be equipped with 4 second blades 5 on the second cutting edge 2, first blade 4, second blade 5 are just to, it means here to face "when first blade 4, second blade 5 interlock, the two take place the striking, and stagger like ordinary daily scissors.

The first blades 4 are arranged on the first blade 1 at equal intervals, the distance between every two adjacent first blades 4 is 1mm, the second blades 5 are arranged on the second blade 2 at equal intervals, the distance between every two adjacent second blades 5 is 1mm, and the umbilical cord tissue can be cut at intervals of 1 mm.

The first blade 1 and the first blade 4 are arc-shaped, are more attached to the shape of the umbilical cord, improve the anti-skidding effect of the anti-skidding teeth 3, and the second blade 5 is semi-elliptical, has the width at two ends larger than the width of the middle part thereof, is matched with the shape of the first blade 4, and is convenient for cutting the umbilical cord tissue.

The working principle is as follows: when the umbilical cord tissue is sheared, the umbilical cord tissue is placed on the first blade 1, one end of the umbilical cord tissue slightly extends out of the first blade 1, then the umbilical cord tissue is sheared, when the second blade 5 is in contact with the umbilical cord tissue, the umbilical cord tissue is pressed by the anti-skidding teeth 3 and the second blade 5 together, the anti-skidding teeth 3 are inserted into the umbilical cord tissue, the umbilical cord tissue is prevented from sliding between the first blade 1 and the second blade 2, then the umbilical cord tissue is cut by the second blade 5 and the first blade 4 together, because the first blade 4 and the second blade 5 are respectively provided with 4 slices, the distance is 1mm, a plurality of slices with the thickness of 1mm can be directly obtained, the obtained slices are continuously sheared for 2 times, and the umbilical cord tissue fragments with the size meeting the requirements can be obtained.

It should be noted that, the number of the first blades 4 and the second blades 5 is 4, which is not equivalent to the limit of the number of the first blades 4 and the second blades 5 in the present invention, and those skilled in the art can increase or decrease the number of the first blades 4 and the second blades 5 according to actual needs.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
