Description

Technical Field

[0001] The utility model relates to the technical field of tissue sectioning, in particular to a tissue sectioning device capable of increasing the adhesion force of samples. Background Art

[0002] Tissue sectioning devices are mainly used to cut biological tissues into extremely thin sections for observation and analysis under a microscope. It can provide key sample preparation means for medical diagnosis, biological research, pathological examination, etc. Through precise sectioning, the cell structure, pathological changes and other microscopic features of tissues can be shown, providing a basis for disease diagnosis and scientific research.

[0003] In the prior art, such as the utility model with the publication number CN220699688U, a tissue wax block sectioning device is disclosed. The tissue section of the biological tissue wax block is directly humidified and de-electrified by a humidifier, which can avoid the problem that the cut wax slices are adsorbed to each other and agglomerated due to the existence of static electricity. And because the humidification process of the humidifier to the biological tissue wax block is instantaneous and continuous, no additional de-electrification operation is required in the middle, so the overall sectioning efficiency is high and the sectioning effect is good. The main structure of this application includes a main base, a wax block clamp seat, a knife seat, a reciprocating mechanism and a feed seat, and a blade is provided on the knife seat; it also includes a spray humidifier, which includes a machine body, a water tank, a fog generator, a spray pipe and a diversion fan. There is a fog generation space in the water tank, the inlet end of the spray pipe is communicated with the fog generation space, and an air inlet hole communicated with the fog generation space is provided on the water tank; the diversion direction of the diversion fan is from the inlet end of the spray pipe to the outlet end of the spray pipe, and the outlet end of the spray pipe faces the wax block clamp seat, solving the problem that in a dry environment (such as the working environment in autumn and winter), static electricity is likely to be generated, and the static electricity easily makes the sections (wax slices) adsorb to each other and agglomerate, resulting in the inability to perform subsequent spreading and fishing of slices.

[0004] In daily work, it is found that when the existing tissue sectioning device is in use, the tissue is usually wrapped in a wax block and then sectioned by the sectioning device. However, when clamping the wax block and the tissue, a splint is usually used to clamp the wax block. Since paraffin has a certain softness at a certain temperature, when the clamping force of the tissue sectioning device acts on the tissue wrapped with paraffin, the paraffin may undergo slight deformation. This deformation may cause the tissue to be unstable during clamping, resulting in shaking and affecting the sectioning, and further leading to the problem of poor stability of the existing sectioning device.

A breathable cloth 54 is provided on one side of the clamping seat 2, and a connecting component 59 is provided between the breathable cloth 54 and the clamping seat 2.

[0024] In this embodiment: when limiting the tissue wrapped with paraffin, the tissue can be first placed in the clamping seat 2, and then the screw rod 51 is rotated. The screw rod 51 drives the clamping plate 52 to clamp the tissue wrapped with paraffin. After clamping, the two telescopic rods 53 are opened, and the two telescopic rods 53 drive the moving plate 55 to move in the cavity 57. Thus, the suction holes 58 cooperate with the breathable cloth 54 to adsorb the tissue wrapped with paraffin, increasing the adhesion force of the tissue and making the sectioning more stable. The breathable cloth 54 can play a role in intercepting and filtering the suction holes 58.

[0025] Specifically, the plurality of suction holes 58 opened on the surface of the clamping seat 2 are arranged at the center of the clamping seat 2, and the plurality of suction holes 58 are equidistantly distributed.

[0026] Specifically, the connecting component 59 includes two inserting blocks 596. The two inserting blocks 596 are respectively fixedly connected to the surface of the breathable cloth 54. Two sliding rods 592 are respectively fixedly connected to both sides of the clamping seat 2. A hollow sleeve 591 is slidably connected to the surface of the sliding rod 592.

The inserting rod 594 is released, and the second spring 595 releases the elastic force, driving the inserting rod 594 to reset. The inserting rod 594 is inserted into the inner wall of the inserting block 596. Then, the elastic force of the first spring 593 can pull the hollow sleeve 591 to one side. The hollow sleeve 591 pulls the inserting block 596 and the breathable cloth 54, so that the breathable cloth 54 is better attached to the clamping seat 2. The tissue wrapped with paraffin is placed in the clamping seat 2. The screw rod 51 is rotated, and the screw rod 51 drives the clamping plate 52 to clamp the tissue wrapped with paraffin. After clamping, the two telescopic rods 53 are opened, and the two telescopic rods 53 drive the moving plate 55 to move in the cavity 57. Thus, the suction holes 58 and the breathable cloth 54 can adsorb the tissue wrapped with paraffin, increasing the adhesion of the tissue and making the slicing more stable.
