Description

Technical Field

[0001] The utility model relates to the technical field of embedding machines, in particular to a biological tissue paraffin embedding machine. Background Art

[0002] An embedding machine, also known as a biological tissue embedding machine or a paraffin embedding machine, is a medical device that embeds human or animal and plant specimens after dehydration and wax immersion for histological diagnosis or research after sectioning. The principle is to place the biological tissue block in melted paraffin, fix it with paraffin, and then use a slicer to cut the tissue into thin slices for research.

[0003] The publication number of the existing public patent is: CN209979345U. A biological tissue paraffin embedding machine that is easy to operate, whose structure includes an embedding table, a power interface, an auxiliary mechanism, a control switch, a paraffin placement bin, a wax discharger, an embedding box bin, a bin cover, a working position, a collection box, a cooling table, a placement plate and an embedding box. The utility model is provided with an auxiliary mechanism at the right end of the front end surface of the embedding table, so that materials or some intelligent devices can be placed on a plate body in the mechanism, and the plate body can support the materials. A magnetic sheet is embedded in the plate body, which can adsorb some intelligent devices and fix the metal part on the back thereof, and exert force on two sets of connecting rods and a tray in the auxiliary mechanism, which can be adjusted at multiple angles to assist the user in embedding, with good effect, making the embedding work more convenient.

[0004] However, the above patent still has certain disadvantages when used: when embedding with paraffin, since there is still a certain distance between the wax discharger and the embedding box containing the biological tissue, the paraffin is easy to impact the bottom of the embedding box when falling, thereby causing the splash of the paraffin liquid, and when the paraffin inside the embedding box is almost full, it is necessary to add paraffin liquid to the inside of the embedding box, and the paraffin liquid at this time will splash out from the inside of the embedding box, splashing onto the surface of the embedding machine, thereby causing pollution to the surface of the embedding machine; at the same time, when the biological tissue is embedded, the staff needs to move the embedded embedding box to the cooling table to cool the paraffin liquid and biological tissue inside the embedding box. If the staff does not hold the embedding box when moving the embedding box, the paraffin liquid and biological tissue inside the embedding box may spill out, and the biological tissue needs to be re-embedded, thereby increasing the production cost of the biological tissue embedding machine, and the overall use effect is not very good, and it is not very convenient to re-take out the solidified paraffin later, which is easy to cause pollution to the hands of the staff and increase the operation intensity of the staff.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0032] In one embodiment, a driving shaft 20 is fixedly installed at the middle position of the bottom of the adjusting disk 2, and the bottom end of the driving shaft 20 is rotatably connected to the bottom end position inside the embedding machine body 1. The outer side of the driving shaft 20 is connected to the second motor 21 through a transmission chain. One end of the driving shaft 20 is located at a position just below one side of the bottom of the adjusting disk 2 and is surrounded by a plurality of groups of threaded rods 17 and sliding rods. A plurality of groups of cooling cylinders 16 are sleeved between the threaded rods 17 and the sliding rods. A plurality of groups of refrigeration fins 19 are arranged on the inner surface of the cooling cylinder 16. One end of the threaded rod 17 penetrates through the surface of one side of the embedding machine body 1 and is connected to the motor 18. The other end of the driving shaft 20 is located at a position just below the other side of the bottom of the adjusting disk 2 and is fixedly installed with a hydraulic rod 22. A ejection disk 23 is installed at the top of the hydraulic rod 22. The cooling cylinder 16 is distributed at a position just below one side of the adjusting disk 2. In this way, the embedding cylinder 3 can be cooled multiple times when its position changes, thereby improving the overall cooling effect, ensuring that the internal high-temperature paraffin can be fully solidified, and facilitating subsequent use.

[0033] In one embodiment, a sealing disk 14 is slidably connected to the interior of the embedding tube 3, an ejector rod 15 is fixedly installed at the middle position of the bottom of the sealing disk 14, and the ejector rod 15 is slidably connected to the bottom of the embedding tube 3.

[0037] In one embodiment, an anti-dropping disc is provided at the bottom of the ejector rod 15. The anti-dropping disc is a common disc structure, but its size is larger than the size of the slot at the contact position between the ejector rod 15 and the bottom of the embedding tube 3, which effectively prevents the ejector rod 15 from falling off from the slot when moving, thereby ensuring the use effect.

[0039] Working principle: In actual use, personnel can put paraffin into the wax discharger 7 and melt the paraffin through the electric heating wire inside the wax discharger 7. Then, the embedding tube 3 containing biological tissue can be placed in the mounting holes 12 at different positions on the surface of the adjusting disk 2 in sequence. Then, the operation of the second motor 21 can be controlled to drive the transmission chain to drive the driving shaft 20, thereby rotating the adjusting disk 2, so that the embedding tube 3 on the surface moves to the position directly opposite the fixed plate 4. Then, the operation of the first motor 8 can drive the screw rod 10 to rotate, thereby moving the moving seat 9 as a whole downward. At this time, the wax injection tube on its surface 5 will be inserted into the bottom end of the embedding tube 3. At this time, the paraffin in the wax discharger 7 can be discharged by opening the control valve 13. At the same time as the paraffin is discharged, the first motor 8 can also run in the reverse direction, thereby driving the movable seat 9 to move upward again as a whole. At this time, the wax injection tube 5 will also gradually move upward from the inside of the embedding tube 3. In this way, it can move as the paraffin gradually increases, ensuring that the paraffin can fully fill the inside of the embedding tube 3. At the same time, the height difference during wax injection can be avoided to cause the paraffin to splash, thereby improving the overall wax injection effect. Then, after an embedding tube 3 is filled, the operation of the second motor 21 can drive the adjustment The disk 2 rotates stably, and the unused embedding tube 3 is moved to the side position of the fixed plate 4. At this time, the embedding tube 3 filled with paraffin can be moved to the position just above the cooling tube 16. At this time, the operation of the motor 18 can drive the rotation of the threaded rod 17, and then the cooling tube 16 is moved to the outer position of the embedding tube 3. At this time, the embedding tube 3 can be cooled by the refrigeration plate 19 on the surface of the cooling tube 16, so as to realize the cooling and solidification operation of the internal paraffin. At the same time, the cooling tube 16 is arranged around the position just below the adjusting disk 2, so that the embedding tube 3 can be cooled multiple times when the position of the embedding tube 3 changes, ensuring that it can The ejector plate 23 is sufficiently cooled and solidified, and then after the cooling is completed, the hydraulic rod 22 on the other side can drive the ejector plate 23 to move upward as a whole. At this time, the ejector plate 23 will contact the ejector rod 15 and move it upward. At this time, the ejector rod 15 can drive the sealing plate 14 inside the embedding tube 3 to move. At this time, the sealing plate 14 can eject the paraffin and biological tissue, and the personnel can remove them conveniently without the need for excessive operation by the personnel, which can reduce the labor intensity of the personnel, improve the convenience of material collection, and facilitate subsequent use. The device as a whole has the advantages of anti-splashing of wax injection, convenient solidification and material collection, and less pollution during transfer between steps.
