The first terminal 13 is provided with a plurality of first protrusions 133 on one side facing the second terminal 14, the second terminal 14 is provided with a plurality of second protrusions 143 on one side facing the first terminal 13, the first protrusions 133 and the second protrusions 143 respectively abut against two sides of the filter screen body 2, the first protrusions 133 and the second protrusions 143 are arranged in a staggered manner with the through holes 21, the first protrusions 133 and the second protrusions 143 realize that the filter screen body 2 is axially and limitedly matched in the accommodating cavity 10, the positioning columns 132 and the positioning holes 142 have similar effects, and the filter screen body 2 can be prevented from being pushed by solid and liquid flowing in the accommodating cavity 10 and shifting when being crushed, and a better crushing effect can be obtained if the first protrusions 133 and the second protrusions 143 are combined.

One surface of the first terminal 13 facing the second terminal 14 is provided with a sealing flange 134, one surface of the second terminal 14 facing the first terminal 13 is provided with a sealing groove 144 matched with the sealing flange 134, the sealing flange 134 and the sealing groove 144 are both arranged at the edge of the cavity 10, and the sealing flange 134 is tightly fitted in the sealing groove 144, so that the sealing fit of the joint of the first terminal 13 and the second terminal 14 is realized, the sealing effect of the cavity 10 is improved, and the substance in the cavity 10 is prevented from overflowing from the gap between the first terminal 13 and the second terminal 14 in the crushing process.

Above-mentioned first terminal 13 or second terminal 14's surface is provided with direction indication mark 145, a direction of filtration for instruct the product, behind the filter screen body 2 who adopts suitable aperture, filter screen body 2 has the filter effect to the loose connective tissue in the adipose tissue, can stop loose connective tissue in one side of filter screen body 2 when broken adipocyte, realize filtering capability, therefore behind direction indication mark 145, can let operating personnel know more conveniently in which one end should be connected to the syringe that has adipose tissue, what one end should be connected to the empty syringe, and behind the repeated push-and-pull syringe many times, can distinguish clearly which is the target syringe (the syringe that does not contain loose connective tissue fast). In the present embodiment, the direction indicator 145 is provided on the surface of the second terminal 14.

The first connection tube 131 and the second connection tube 141 are both configured as standard luer connectors, which can improve the simplicity of the connection structure and the compatibility between different products, and accordingly, the present invention can be externally connected with a luer syringe in actual use.

Referring to fig. 5, one of the usage modes of the crushing device is as follows:

according to the direction indicator 145, a syringe with adipose tissue (including loose connective tissue a and fat cells B attached thereto, both shown in block form in fig. 5 to mainly indicate their positional relationship) and another empty syringe are connected to the first connection tube 131 of the first terminal 13 and the second connection tube 141 of the second terminal 14, respectively.

Referring to the upper part of fig. 5, in the process that the hollow syringe pushes adipose tissues to the hollow syringe in the right direction, the adipose tissues are injected into the cavity 10 and pass through the through holes 21 of the strainer body 2, the loose connective tissue a is blocked, the adipose cells B are pushed through the through holes 21 due to the aperture of the through holes 21 and the pressure on the left side, the sharp protrusions 22 in the through holes 21 cut the cell walls of the adipose cells B, so that the cell nuclei, cytoplasm and the like of the adipose cells B flow out to pass through the through holes 21 more easily, and the loose connective tissue a and the crushed adipose cells B are separated at both sides of the strainer body 2;

referring to the lower part of fig. 5, after the piston of the empty syringe is pushed back, the fat cells B on the right side of the filter screen body 2 pass through the through holes 21 again to be crushed again, and meanwhile, the loose connective tissue a shielded around the through holes 21 is pushed away, so that other fat cells B can pass through, and at the moment, the loose connective tissue a and the crushed fat cells B are on the left side of the filter screen body 2;

afterwards, after operating personnel pushed two syringes repeatedly, can carry out repeated breakage to adipocyte B, finally satisfy broken demand, loose connective tissue A in the adipose tissue is kept off in one side by filter screen body 2 all the time simultaneously, realizes filtering.

Through the scheme, the sharp bulge 22 is arranged on the inner wall of the through hole 21, so that the integral crushing effect can be improved without reducing the aperture on the basis of the conventional filter screen, and the operation is not more laborious; after the crushing device is applied, only the first opening 11 and the second opening 12 are respectively connected with the injector, and in the process of pushing and pulling the injector, the sharp bulge 22 on the inner wall of the through hole 21 can cut other connective tissues and fibrous tissues in the adipose tissues while scratching the cell walls of the adipose cells, so that the crushing effect is achieved; meanwhile, aiming at adipose tissues with different fineness extracted by liposuction needles or liposuction equipment with different apertures, a cutting filter screen with a through hole 21 aperture with a proper size can be reasonably selected, and the crushed adipose tissues are left on one side pointed by the arrow, so that subsequent treatment is facilitated; the invention has simple structure and convenient operation, does not need a high-cost crushing device, can realize the quick crushing of the fat cells only by manually operating the push-pull injector, and meets the clinical use requirement.
