Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a pathological slice forming device for clinical testing. Background Art

[0002] When the paraffin slicer is working, its driving device drives the cutting knife to rotate through the transmission system, and the sliding device pushes the sample clamp forward so that the sample is close to the cutting knife to complete the sample slicing. After the slicing is completed, the operator can observe through a microscope and select the best slice.

[0003] Pathological paraffin sectioning is a preparation technology widely used in disciplines such as pathology and forensic medicine. It is mainly used to observe and study the morphological changes of tissues and cells. The fixed specimens are sent to the pathology department, where pathologists take samples and place them in a fully automatic dehydrator for dehydration, which usually takes 16 hours. During this process, the specimens will undergo tissue fixation, dehydration, transparency, wax immersion and other steps. After embedding, the pathology technician places the wax block on the microtome for slicing.

[0004] However, in the process of pathological paraffin sectioning, the cut wax slices are often prone to wrinkles and breaks when stacked. In order to solve this problem, the technician needs to use a brush to carefully peel the wax slices from the blade immediately after slicing. This operation requires extremely high slicing skills from the technician, and requires experienced technicians to ensure the integrity and flatness of the wax slices. However, with the continuous rotation of the hand wheel, the number of wax slices gradually increases. If the wax slices cannot be separated in time, the wax slices need to be separated and resampled after stacking, which undoubtedly increases the difficulty of operation and sampling time. Although the prior art also attempts to place a conveyor belt on the knife holder to realize the transmission of the wax slices, the wax slices are still prone to wrinkles because the position of the wax slices cannot be guided and leveled in time, resulting in low efficiency of continuous sampling, and the molding degree of the wax slices is also affected.

When the slicing host drives the embedding block 103 on the second adjustment seat 102 to move, the sensor 303 receives a signal and can control the power source 508 to start through the controller. The power source 508 can drive the eccentric wheel 509 to rotate, and the second elastic member 308 can drive the moving seat 307 to move. The moving seat 307 drives the driving unit 5 to move and is always in contact with the eccentric wheel 509. The driving unit 5 drives the extraction unit 4 to move downward. As the extraction unit 4 moves downward, the extraction When one side of the part 4 contacts the inclined surface of the knife holder 3, it will rotate slightly on one side of the driving part 5, and the extraction part 4 drives the pathology glass slide 402 to gradually fit with the wax sheet from a position close to the blade 302. After the cam continues to rotate, the driving part 5 can be lifted up. When the driving part 5 moves upward, the protrusion 505 is squeezed by the swing arm 506 and rotates and moves, driving the driving wheel 503 to rotate unidirectionally, and the driving wheel 503 drives the second transmission wheel 504 to rotate. The second transmission wheel 504 drives the first transmission wheel 502 to rotate through the transmission belt 510, and the first transmission wheel 502 drives the rotating seat 501 and the extraction part 4 to rotate, so that the extraction part 4 can be controlled to rotate and turn over.

[0080] Reference Figure 6The extraction part 4 also includes: a rotating block 409, which is installed at one end of the extraction part 4, and a rotating seat 501 is installed on one side of the driving part 5, one end of the rotating seat 501 is connected to the first transmission wheel 502, and the other end is provided with a groove, and the rotating block 409 is connected in the groove; a third elastic member 410, one end of which is connected to the rotating block 409, and the other end is connected to the side wall of the groove. The third elastic member 410 adopts a coil spring and can also adopt a torsion spring. When the extraction part 4 drives the rotating block 409 to rotate, the third elastic member 410 can provide an initial position restoring force for the rotating block 409.

[0081] Reference Figure 1 and Figure 2 , a collecting tray 2 is installed on one side of the slicing part 1, and is used to collect wax fragments generated during the slicing process; a guide rail 201 is installed in the collecting tray 2, and the knife seat 3 is connected to the guide rail 201 to provide a smooth moving path for the knife seat 3; a first adjusting seat 101 is installed on the slicing part 1 to adjust the height and angle of the slice; a second adjusting seat 102 is installed on the first adjusting seat 101, and is used to fine-tune the embedding block 103 in the horizontal and vertical directions; the embedding block 103 is installed on one side of the second adjusting seat 102.

[0082] During use, after the embedding block 103 is securely installed on the second adjustment seat 102, the slicing host begins to accurately control the movement of the embedding block 103. When the embedding block 103 contacts the blade 302, the blade 302 quickly and accurately slices the embedding block 103. When roughly trimming the pathological section, the sensor 303 is turned off, and the extraction part 4 is not working at this time. Before slicing, the sensor 303 is turned on, and the sliced ​​wax sheet immediately slides into the narrow space between the extraction part 4 and the material receiving platform 301. While the slicing host drives the embedding block 103 to move, the sensor 303 immediately captures the action signal and instructs the power source 508 to start through the controller. The power source 508 is quickly activated to drive the eccentric wheel 509 to start rotating. At this time, the second The effect of the elastic member 308 is apparent. It pushes the moving seat 307 to move smoothly, ensuring that the driving part 5 always maintains close contact with the eccentric wheel 509. As the eccentric wheel 509 rotates, the driving part 5 drives the extracting part 4 to move slowly downward. When one side of the extracting part 4 contacts the inclined surface of the knife seat 3, it will rotate slightly under the action of the driving part 5, and at the same time drive the rotating block 409 to rotate. In this process, the third elastic member 410 provides the necessary restoring force for the rotating block 409 to ensure the smooth and precise rotation. As the extracting part 4 continues to move downward, the pathology glass slide 402 gradually fits with the wax sheet from the position close to the blade 302, realizing the damage-free collection of the wax sheet. Subsequently, the eccentric wheel 509 continues to rotate, and its raised part lifts up the driving part 5, so that it moves upward. At this time, the protrusion 505 is squeezed by the swing arm 506 and rotates and displaces. This mechanism ensures the unidirectional rotation of the driving wheel 503. The rotation of the driving wheel 503 further drives the rotation of the second transmission wheel 504. The second transmission wheel 504 transmits power to the first transmission wheel 502 through the transmission belt 510. After receiving the power, the first transmission wheel 502 drives the rotating seat 501 and the extraction part 4 to rotate together, realizing the automatic turning function of the extraction part 4. When the eccentric wheel 509 completes a full circle of rotation and returns to the initial position, the second elastic member 308 plays a role again, pushing the moving seat 307 and the driving part 5 to reset, preparing for the next downward pressing action. In the process of the driving part 5 moving downward, the swing arm 506 It rotates due to the squeezing of the protrusion 505, and at the same time drives the rotating block 511 to rotate in the rotating groove 304. The first elastic member 305 ensures that the rotating block 511 can be accurately reset after each rotation. During the rotation of the entire extraction part 4, the connecting rod 407 always remains perpendicular to the ground on the rotating seat 406. During the continuous slicing process, multiple pathology slides 402 can be collected continuously. After multiple pathology slides 402 are collected and sliced, they are uniformly removed and replaced with new ones. When the conductive contacts on the connecting rod 407 come into contact with different power connectors 408, the circuit can be automatically switched to ensure that the heating element 401 is energized and the heating function is turned on in time when needed, providing a constant heat source for the pathology slide 402 and ensuring the flatness and integrity of the wax sheet.

[0083] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0084] Through the multi-faceted design of the extraction part 4, the wax slices can be continuously collected and gradually adhered to the wax slices during the slicing process, effectively solving the problems of wrinkles and breaks when the wax slices are stacked. The non-parallel setting of the extraction part 4 and the coordination with the inclined surface of the knife holder 3 enable the wax slices to be flatly and continuously attached to the pathology glass slide 402, greatly improving the molding and flatness of the wax slices.

[0085] Through automation and intelligent design, the operation process is greatly simplified, the slicing technology requirements are reduced, and there is no need to use a brush to manually peel off the wax slices, which reduces the errors and uncertainties of human operation and improves work efficiency and sampling quality.

[0086] The continuous and stable extraction and flipping of wax sheets are realized, the separation and resampling problems caused by wax sheet stacking are avoided, the efficiency of continuous sampling is improved, and the operation difficulty and sampling time are reduced.
