Description
【Technical field】
The utility model is related to a kind of device shredding tissue block, more particularly to a kind of umbilical cord and placenta tissue block of shredding
Device.
【Background technology】
Umbilical cord mesenchymal stem cells (Mesenchymal Stem Cells, MSCs) refer to being present in neonatal umbilical cord tissue
In a kind of versatile stem cell, it can be divided into many kinds of histocytes, have wide potential applicability in clinical practice.
Fresh and healthy umbilical cord is taken, after being rinsed well with PBS, blood vessel is removed with scissors tweezers, strips out the Fahrenheit glue group of the inside
It knits, gained tissue is fully shredded to 1mm3~3mm3 sizes, α-MEM culture solutions are added and are placed in 37 DEG C, 5% CO2 incubators
It cultivates, 10%FBS, 100U/ml penicillin, 100U/ml streptomysins is contained in culture solution.After umbilical cord tissue culture 5-7 days, it is seen that have
Part cell climbs out of around tissue block, and form is in tiny fusiformis, and after a week, cell starts to be proliferated rapidly, forms size not
Deng cell colony, after cell covers with, with 0.25% trypsin digestion pass on.In umbilical cord mesenchymal stem cells culture,
The size of tissue block has cell culture important influence.Therefore, gained tissue is cut into the tissue of 1mm3~3mm3 sizes
Block is important a ring.
Technological deficiency at present：Medical scissors shred tissue block, such the disadvantage is that labor intensive, tissue block size cannot reach
It is irregular to 1mm3~3mm3, it influences cell and climbs out of rate, for this purpose, it is proposed that one kind shredding umbilical cord and placenta tissue block
Device.
【Utility model content】
The main purpose of the utility model is to provide a kind of devices shredding umbilical cord and placenta tissue block, can effectively solve
Certainly the problems in background technology.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of device shredding umbilical cord and placenta tissue block, including it is rotating bar, mechanical blades, the plate layer with sieve pore, single
Blade, appliance cover and tissue block collection device, the tissue block collection device top are equipped with the plate layer with sieve pore and set
The mechanical blades at the top of the plate layer with sieve pore are set, the mechanical blades are made of single blade, and single blade is specially more
Group, the mechanical blades top are provided with appliance cover, and the rotating bar passes through the center of appliance cover to be fixedly connected with mechanical blades.
Further, the slot size in the plate layer with sieve pore is 3 cubic millimeters.
Compared with prior art, the utility model has the advantages that：Entire liquid process of changing is simple and convenient, is easy to grasp
Make, reduces artificial take；Tissue is cut into required size, improves cell culture efficiency.And it can be used for placenta mesenchyma
Stem cell is cultivated, and tissue shreds.

【Specific implementation mode】
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
As shown in Figs 1-4, a kind of device shredding umbilical cord and placenta tissue block, including rotating bar 1, mechanical blades 2, with sieve
Plate layer 3, single blade 4, appliance cover 5 and the tissue block collection device 6 in hole, 6 top of the tissue block collection device are provided with
There is the plate layer 3 of sieve pore and the mechanical blades 2 at the top of plate layer 3 with sieve pore are set, the mechanical blades 2 are by 4 groups of single blade
At, and single blade 4 is specially multigroup, and 2 top of the mechanical blades is provided with appliance cover 5, and the rotating bar 1 passes through appliance cover
5 center is fixedly connected with mechanical blades 2.
Wherein, the slot size in the plate layer 3 with sieve pore is 3 cubic millimeters.
It should be noted that the utility model is a kind of device shredding umbilical cord and placenta tissue block, when work, 1, use
Tissue is cut into the tissue block of 1mm3~3mm3 sizes by machine power.
2, fresh and healthy umbilical cord is taken, after being rinsed well with PBS, blood vessel is removed with scissors tweezers, strips out the Fahrenheit glue of the inside
Tissue.
3, device for opening lid 5 removes power rail and mechanical blades 2, and tissue is placed on the plate layer 3 with sieve pore.
4, tissue block collection device 6 is connected with device is shredded, can be dismantled between the two.
5, mechanical blades 2 are connected, loads onto power in rotating bar 1, opens power supply, start to shear, shearing terminates, and collects tissue
Block carries out paving bottle culture.
6, mechanical blades 2 are detachably cleaned, sterilizing, using stainless steel.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
