Description

Technical Field

[0001] The present invention belongs to the technical field of tumor sample slicing equipment, and specifically refers to a pathological slice detection device for oncology. Background Art

[0002] Tumor slicing is a key technology for clinically diagnosing the nature of tumors. By surgically removing the diseased tissue and making it into a thin slice with a thickness of 3-4 microns, after staining, the cell morphology and tissue structure are observed under a microscope to judge the benign and malignant nature, type, and degree of differentiation of the tumor, etc.

[0003] Currently, when slicing tumor samples, it is necessary to appropriately increase the height of the tumor sample or decrease the height of the cutting tool. Multiple cuts of the sample require multiple adjustments of the spatial height. At the same time, it is also necessary to freeze and shape the surface of the tumor sample to ensure that the thickness of the cut sample slices is uniform. Summary of the Invention

[0004] In view of the above situation, in order to ensure the structural stability of the cutting area of the tumor sample and be able to reciprocate and cut the tumor sample with a constant thickness multiple times, the present invention provides a pathological slice detection device for oncology, which can not only freeze and shape the cutting area before cutting, but also perform reciprocating cutting operations on the tumor sample with the same thickness. The device has a simple structure and is easy to operate.

The tumor support plate 31 is fixedly installed in the housing 1. The splint chute 33 is fixedly arranged in the tumor support plate 31. The horizontal splint 32 is slidably engaged in the splint chute 33. The horizontal splint 32 is connected to the splint chute 33 by a spring. The splint limit groove 34 is fixedly arranged on the upper wall of the horizontal splint 32. The splint limit insertion plate 35 is slidably engaged and installed on the tumor support plate 31.

[0033] A block hiding groove 38 is provided in the tumor support plate 31. A positioning block slot 39 is provided on the horizontal splint 32. A limiting block 40 that is slidably engaged is provided in the block hiding groove 38. The limiting block 40 is slidably engaged in the positioning block slot 39. An electromagnet 41 is provided in the block hiding groove 38. An electromagnet 42 is provided on the limiting block 40. A spring is used to connect the block hiding groove 38 and the limiting block 40.

[0034] The semiconductor refrigeration sheet 5 is slidably engaged and installed on the horizontal translation rack 24.

[0035] There are two groups of tumor support plates 31. A slidably engaged support plate 23 is provided between the two groups of tumor support plates 31.

[0036] During specific use, the tumor sample is placed at the middle position between the two groups of tumor support plates 31. The tumor sample presses on the splint limit insertion plate 35, causing the splint limit insertion plate 35 to slide down. Since the splint limit groove 34 is designed as a triangular structure, when the splint limit insertion plate 35 moves downward, it pushes the horizontal splint 32 to slide horizontally, and the sample fixing plate 37 fixes both sides of the tumor sample. During the horizontal movement of the horizontal splint 32, the pressing action of the side wall of the horizontal splint 32 on the limiting block 40 disappears. The spring in the block hiding groove 38 pushes the limiting block 40 outwards, and the limiting block 40 enters the positioning block slot 39, so that the position of the horizontal splint 32 relative to the tumor support plate 31 is fixed. Insert the semiconductor refrigeration sheet 5 into the card slot on the horizontal translation rack 24. The semiconductor refrigeration sheet 5 is powered on to work, playing a role in cooling and shaping the surface of the tumor sample. Press the slicing cutter head 26 into the tool sleeve 25. The bottom of the first flipping bracket 27 is pressed by the cutter head, thus breaking the balance of the first flipping bracket 27. The first flipping bracket 27 rotates, and the upper end of the first flipping bracket 27 presses the top wall of the slicing cutter head 26. During the rotation of the first flipping bracket 27, the first bracket limiting protrusion 29 pops out from the first protrusion clamping groove 30. The first bracket limiting protrusion 29 restricts the rotation direction of the first flipping bracket 27, and the slicing cutter head 26 is fixed relative to the tool sleeve 25. Slice the tumor sample. Push the tool sleeve 25 horizontally. The slicing cutter head 26 cuts the upper surface of the tumor sample. Since the slicing cutter head 26 is connected to the semiconductor refrigerating sheet 5 through a horizontally moving rack 24 with a fixed structure, when the semiconductor refrigerating sheet 5 leaves the surface of the tumor sample, the slicing cutter head 26 slices the leaving area. When the horizontally moving rack 24 moves, it drives the first transmission gear 8 to rotate. The kinetic energy of the first transmission gear 8 is transmitted through the bracket and moves to the sun gear 9. Through the transmission of the planetary gear 10 structure, the angular velocity is attenuated in equal proportion. The second transmission gear 13 is fixedly connected to the three-phase bracket 12 through the bracket. When the three-phase bracket 12 rotates, the second transmission gear 13 obtains the kinetic energy transmitted from the three-phase bracket 12 and squeezes the steering limiting block 16 in the second tooth ring 14, causing the steering limiting block 16 to squeeze the steering limiting groove 15. At this time, the steering limiting block 16 cannot hide into the steering limiting groove 15 and can only press on the side wall of the steering limiting groove 15, driving the second tooth ring 14 to rotate. The rotation of the second tooth ring 14 causes the second upward pushing rack 22 to move upward along the direction of the second rack clamping groove 21, pushing the tray 23 upward. The tray 23 drives the tumor sample to move upward, and the sample fixing plate 37 moves upward with the tumor sample. Since the spatial height position of the cutter head remains unchanged and the position of the tumor sample rises, it is beneficial for the second cutting of the tumor sample. Move the semiconductor refrigerating sheet 5 backward to return to the area where the tumor sample is located. The horizontally moving rack 24 moves in the reverse direction, and the first transmission gear 8 rotates in the reverse direction. The second transmission gear 13 rotating in the reverse direction obtains the power of reverse rotation. However, the second transmission gear 13 rotating in the reverse direction squeezes the steering limiting block 16, and the steering limiting block 16 is squeezed into the steering limiting groove 15 and cannot drive the second tooth ring 14. Therefore, the second upward pushing rack 22 does not have the effect of moving, ensuring the relative fixation of the spatial position of the tumor sample. When a group of samples is cut, when replacing with a new group of samples, the first electromagnet 41 and the second electromagnet 42 are energized, and the limiting block 40 hides into the block hiding groove 38. The sample on the tumor tray 31 loses the pressing of the horizontal clamping plate 32, and the sample can be removed. To restore the spatial height of the support plate 23, the horizontal displacement limit pull rod 18 is shifted, causing the external sleeve 17 to drag the second gear ring 14 to move horizontally. The second gear ring 14 separates from the second upward push rack 22, and the spring at the bottom of the second upward push rack 22 pulls the second upward push rack 22 downward, causing the support plate 23 to move downward. Then, the limit pull rod 18 is released, and the spring in the sleeve limit tube 20 pushes the second gear ring 14 to the concentric position with the second transmission gear 13 for subsequent cutting operations.
