Description

Technical Field

[0001] The invention relates to the technical field of pathological sampling, and in particular to a cardiovascular pathological sampling and slicing device. Background Art

[0002] Cardiovascular disease is one of the leading causes of death worldwide, and its pathological changes are often diagnosed and studied through pathological sections. As a basic medical diagnostic method, pathological sections can effectively help doctors understand the microstructure of tissues and make correct diagnosis and treatment decisions.

[0003] In cardiovascular pathology, paraffin sealing can fix tissue samples such as the heart and blood vessels to prevent the tissue from being corrupted, degraded or structurally changed after sampling, thereby maintaining the long-term stability of the sample. At the same time, paraffin sealing can make soft tissues harder and easier to cut. Therefore, the existing slicing devices are mainly used to slice pathological paraffin blocks. In a Chinese patent (application number: CN202321225655.X), a double-guide rail combined pathological paraffin slicer is disclosed, including a slicer base, on which a feeding device and a knife holder base are installed, and a knife holder is arranged on the knife holder base. The feeding device includes a transverse feeding device and a vertical base combination, on which a wax block clamp is installed, and the vertical base combination includes a column fixed on the base and a vertical slide seat that can slide back and forth along the column. The transverse feeding device is transversely penetrated and installed on the vertical slide seat, and the end of the column close to the wax block clamp and the end away from the wax block clamp are connected to the corresponding vertical slide seat through a pair of longitudinal guide rails.

[0004] This patent and the prior art have the following technical problems in actual use: 1. Since the required pathological sections are relatively thin, the cut pathological paraffin sections are usually curled. The curled paraffin sections will increase the difficulty of operation, especially when the sections are dewaxed, restained or otherwise processed. The curled sections are easily damaged or fall off, further affecting the progress of pathological analysis.

[0005] 2. At the same time, thinner pathological sections are prone to damage, cracks, warping or falling off during the collection and transportation process.

[0022] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Embodiment 1, as Figure 1-Figure 10 As shown, a cardiovascular pathology sampling and slicing device comprises a base 1, a driving assembly 2 is fixedly mounted on the top of the base 1, a slicing platform 4 is slidably connected to the top of the base 1, the slicing platform 4 is located on the left side of the driving assembly 2, a clamping assembly 3 is mounted on the left side of the driving assembly 2, the driving assembly 2 can drive the clamping assembly 3 to slide up and down, and can drive the clamping assembly 3 to approach the slicing platform 4, and the clamping assembly 3 can clamp the pathology wax block; The slicing platform 4 is tilted in design, and the right end is higher than the left end. A slicing knife 41 is fixedly installed on the right end of the slicing platform 4. A cutting opening 42 is provided through the top of the left half of the slicing platform 4. A film roller 45 is rotatably installed on the bottom of the slicing platform 4. A recycling roller 44 is rotatably installed on the left end of the slicing platform 4. The recycling roller 44 is driven by a recycling motor. A film guide hole is provided inside the slicing platform 4. The film guide hole is close to the slicing knife 41. The film on the film roller 45 passes through the film guide hole and is wound on the recycling roller 44. A heat setting component 5 is fixedly mounted on the top of the right half of the slice carrier 4, and the heat setting component 5 can heat-set the paraffin slice on the film. A cutting component 6 is arranged just above the cutting opening 42, and the cutting component 6 can cut the film.

[0024] When in use, the pathological wax block is clamped on the clamping component 3, the equipment is started, and the driving component 2 drives the clamping component 3 to move up and down. When the clamping component 3 descends, the slicing knife 41 cuts the pathological wax sheet, and the cut pathological wax sheet enters the heat-setting component 5, and the pathological wax sheet is heat-set on the film. At the same time, the recovery motor drives the recovery roller 44 to rotate, and the recovery roller 44 rewinds the film. The film brings the pathological wax sheet out of the heat-set pathological wax sheet and brings it to the cutting port 42 position. Then the cutting component 6 cuts the film, and the pathological wax sheet on the film falls through the cutting port 42 together with the film. Through the setting of the film, the pathological wax sheets can be stably stacked together after cutting, which is convenient for later layered analysis, and the shape of the pathological wax sheets remains stable during operation, and later processing is also more convenient. It should be noted that the width of the cutting port 42 is less than the width of the film, so the recovery roller 44 can stably rewind the excess film. When the clamping component 3 rises above the slicing knife 41, the driving component 2 drives the clamping component 3 to approach the slicing carrier 4, and the moving distance is the cutting thickness, so that pathological slicing can be continuously performed.

[0025] The film of the present invention adopts a polypropylene film, which has the following characteristics: the polypropylene film has good transparency, a smooth surface, and is resistant to chemical corrosion. Its surface can adhere to paraffin wax and is not easily deformed at high temperatures, so it helps to fix slices and improve the adhesion effect of paraffin wax.

[0026] Embodiment 2, on the basis of the above embodiment, further includes that the driving component 2 includes a machine head 21 fixedly mounted on the top of the base 1, a driving motor 22 is fixedly mounted inside the machine head 21, a crank wheel 23 is fixedly mounted on the output end of the driving motor 22, a lever 24 is rotatably mounted on the outer side of the crank wheel 23, a sliding window is opened on the left side of the machine head 21, a transmission slide frame 25 is slidably connected inside the sliding window, a transmission guide rail 26 is fixedly mounted on the right side of the transmission slide frame 25, the lever 24 is inserted into the transmission guide rail 26, and the distance from the lever 24 to the center of the crank wheel 23 is the same as the length of the transmission guide rail 26, a driving wheel is rotatably mounted inside the transmission slide frame 25, a telescopic screw 28 is threadedly connected to the inner side of the driving wheel, the telescopic screw 28 is fixedly mounted on the clamping component 3, and the clamping component 3 is slidably connected to the left side of the transmission slide frame 25.

[0027] When in use, the equipment is started, and the driving motor 22 is energized. The driving motor 22 drives the crank wheel 23 to rotate, and the crank wheel 23 drives the lever 24 to rotate. The lever 24 slides inside the transmission guide rail 26. At the same time, the lever 24 drives the transmission guide rail 26 to rise and fall, and the transmission guide rail 26 drives the transmission slide frame 25 to rise and fall, and the transmission slide frame 25 drives the clamping assembly 3 to rise and fall. The driving structure is simple. When the clamping assembly 3 rises above the slicing knife 41, the driving wheel rotates, and the driving wheel drives the clamping assembly 3 to approach the slicing carrier 4 through the telescopic screw 28, and the moving distance is the cutting thickness, so that pathological slicing can be performed continuously.

[0028] Embodiment three, on the basis of the above embodiments, further includes: the driving wheel is composed of a transmission ratchet 27 and an external gear 29, the external gear 29 is rotatably mounted on the outside of the transmission ratchet 27, a pawl 210 is hinged on the inner wall of the external gear 29, a support rod 211 is fixedly mounted inside the machine head 21, an electric telescopic rod 212 is fixedly mounted on the outside of the support rod 211, a mounting plate 213 is fixedly mounted on the telescopic end of the electric telescopic rod 212, a rack group 214 is fixedly mounted on the outside of the mounting plate 213, the rack group 214 is composed of a plurality of rack groups, and the lengths of the plurality of rack groups are different.

[0029] When the clamping assembly 3 descends, the rack set 214 causes the outer gear 29 to rotate. At this time, the outer gear 29 cannot drive the transmission ratchet 27 to rotate through the pawl 210, and the pathological wax block is sliced ​​normally. When the clamping assembly 3 rises above the slicing knife 41, the outer gear 29 engages with a group of racks in the rack set 214. At this time, the outer gear 29 can drive the transmission ratchet 27 to rotate through the pawl 210, and the transmission ratchet 27 drives the clamping assembly 3 to approach the slicing carrier 4 through the telescopic screw 28, and the moving distance is the cutting thickness, so that pathological slicing can be continuously performed. Therefore, the clamping assembly 3 can be telescopically controlled while it is rising and falling, and the structure is simple.

[0030] At the same time, since the rack group 214 is composed of multiple groups of racks, and the lengths of the multiple groups of racks are different, the electric telescopic rod 212 is controlled to operate, and the electric telescopic rod 212 drives the rack group 214 to move relative to the outer gear 29 through the mounting plate 213, so that different racks can mesh with the outer gear 29. Since the lengths of the multiple groups of racks are different, the telescopic distance of the clamping assembly 3 can be controlled at a single time, which is suitable for pathological wax block sections of different thicknesses, has a wide range of applications, and is easy to adjust. High-precision adjustment can be achieved by setting the number of teeth.

[0031] Embodiment 4, on the basis of the above embodiments, further includes that the clamping assembly 3 includes a clamping seat 31, the clamping seat 31 is fixedly mounted on the telescopic screw 28, a side slide plate 32 is arranged on the right side of the clamping seat 31, a sliding opening is opened on the left side of the transmission slide frame 25, the side slide plate 32 passes through the sliding opening, two groups of upper positioning blocks 33 are fixedly installed on the upper part of the left side of the clamping seat 31, a swing groove is opened in the middle of the left side of the clamping seat 31, a swing rod 34 is hinged inside the swing groove, a lower clamping block 35 is arranged at the bottom end of the swing rod 34, and a clamping top spring 36 is arranged between the swing rod 34 and the inner wall of the swing groove.

[0032] Furthermore, a sliding hole 37 is provided on the inner wall of the swing groove, and a locking slider 38 is slidably connected inside the sliding hole 37. The locking slider 38 is inclined at one end close to the swing rod 34. A threaded hole is provided on the outer side of the clamp seat 31, and the threaded hole penetrates into the sliding hole 37. A locking screw 39 is threadedly connected inside the threaded hole, and the locking screw 39 is rotatably connected to the locking slider 38.

[0033] When clamping, the upper part of the swing rod 34 is pushed to the left, and the swing rod 34 drives the lower clamping block 35 to swing to the right. At this time, the pathological wax block is placed between the upper positioning block 33 and the lower clamping block 35, and then the swing rod 34 is released, and the clamping top spring 36 pushes the swing rod 34 to reset, and the swing rod 34 drives the lower clamping block 35 to clamp the pathological wax block. After clamping is completed, the locking screw 39 is rotated, and the locking screw 39 drives the locking slide block 38 to approach the swing rod 34. The locking slide block 38 gives the upper part of the swing rod 34 a rightward thrust through the inclined surface, causing the lower clamping block 35 to have a tendency to swing to the left, thereby improving the clamping stability and being able to lock the swing rod 34 for easy clamping.

[0034] Embodiment 5, on the basis of the above embodiment, further includes: the heat setting component 5 includes an outer sliding frame 51 fixedly mounted on the slicing platform 4, the inner sliding frame 51 is slidably connected with a setting slide plate 52, the setting slide plate 52 is composed of a sliding portion and a flattening portion, a setting distance is arranged between the sliding portion and the slicing platform 4, the flattening portion is designed to be parallel to the clamping component 3, and the top end of the flattening portion is inclined away from the clamping component 3, a heating cylinder 53 is fixedly mounted on the top of the sliding portion, a fan 54 is fixedly mounted on the top of the heating cylinder 53, a heat setting head 55 is arranged inside the sliding portion, and the heat setting head 55 is connected to the heating cylinder 53 through a hot air pipe.

[0035] Furthermore, an adjusting motor 56 is fixedly installed on the outer side of the outer sliding frame 51 , an adjusting screw 57 is fixedly installed on the output end of the adjusting motor 56 , an adjusting nut 58 is fixedly installed on the top of the sliding part, and the adjusting nut 58 is threadedly connected to the adjusting screw 57 .

[0036] When the clamping assembly 3 rises above the slicing knife 41, the outer gear 29 meshes with a group of racks in the rack group 214. At this time, the outer gear 29 can drive the transmission ratchet 27 to rotate through the pawl 210, and the transmission ratchet 27 drives the clamping assembly 3 to approach the slicing platform 4 through the telescopic screw 28. The cut surface of the pathological wax block is pressed against the flattening part. When the clamping assembly 3 descends, the flattening part can flatten the cut surface to improve the subsequent cutting quality. At the same time, the distance between the right side of the flattening part and the slicing knife 41 is just the cutting distance, which prevents the uncut part from being broken in advance and ensures high cutting quality. The cut pathological wax sheet enters the shaping distance, and the fan 54 blows cold air into the heating cylinder 53, and the airflow is heated. The heated airflow is blown onto the pathological wax sheet through the heat setting head 55. While blowing the pathological wax block flat, the pathological wax sheet can be softened so that it can be attached to the film, and the heat setting effect is good.

[0037] By controlling the adjustment motor 56 to be energized, the adjustment motor 56 drives the adjustment screw 57 to rotate, and the adjustment screw 57 drives the shaping slide plate 52 to slide through the adjustment nut 58, thereby changing the distance between the right side of the flattening portion and the slicing knife 41 so that the distance is the same as the cutting thickness of the pathological wax film.

[0038] Embodiment 6, on the basis of the above embodiment, further includes: the cutting assembly 6 includes a bracket 61 fixedly mounted on the slicing carrier 4, a tension spring 62 is fixedly mounted on the inner side of the bracket 61, a cutting frame 63 is fixedly connected to the bottom of the tension spring 62, the cutting frame 63 can pass through the cutting opening 42, a guide column 64 is fixedly mounted on the top of the cutting frame 63, the guide column 64 is slidably connected in the bracket 61, a cutting motor 65 is fixedly mounted on the outer side of the bracket 61, a cam 66 is fixedly mounted on the output end of the cutting motor 65, the cam 66 touches the top of the cutting frame 63, a cam opening is opened inside the bracket 61, and the cam 66 is located in the cam opening.

[0039] Furthermore, the fan 54 is connected to the cutting frame 63 through a cold air duct.

[0040] During cutting, the recovery motor drives the recovery roller 44 to rotate, and the recovery roller 44 reels the film. The film brings the pathology wax sheet out of the heat-set pathology wax sheet to the cutting port 42 position, and then the cutting motor 65 drives the cam 66 to rotate, and the cam 66 drives the cutting frame 63 to descend. The cutting frame 63 cuts the film through the cutting port 42. At the same time, the fan 54 delivers cold air to the cutting frame 63 through the cold air duct, which can cool the heat-set pathology wax sheet, so that the pathology wax sheet can better fit on the film. At the same time, the cut film can be blown off the cutting port 42 to prevent the film from remaining in the cutting frame 63, and the cutting and unloading effect is good.

[0042] After the initial position of the slicing platform 4 is adjusted, the locking bolt 47 is screwed down to fix the slide 46 on the base 1, thereby locking the slicing platform 4 to prevent it from moving during the cutting process. By setting the unloading inclined bucket 43, the film can be unloaded more stably and the unloading effect is good.
