Description

Technical Field

[0001] The invention relates to the technical field of pathological section preparation, in particular to a device for quickly preparing pathological sections that is easy to operate. Background Art

[0002] Pathological sectioning refers to taking a certain size of diseased tissue and making pathological sections using pathological histological methods. The diseased tissue is usually embedded in a paraffin block and cut into thin slices using a microtome. The working principle of the microtome is to first clamp the paraffin block and lift it up and down, and then use the blade to slice it during the lifting process. Every time the sensor senses the lifting of the paraffin block, the stepper motor will drive the blade forward a certain distance so that the blade adapts to the remaining thickness of the paraffin block after each slicing, thereby achieving rapid slicing.

[0003] Existing microtomes use sensors to monitor the rise and fall of paraffin blocks and, based on this, use motors to drive the blades to slice the increasingly thin paraffin blocks to ensure uniform thickness of slices each time. However, this method relies on the accuracy and feedback speed of sensor detection, as well as the accuracy of the distance the stepper motor drives the blades to move each time, which places high demands on the accuracy and response speed of the motors and sensors.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a device for rapid preparation of pathological sections that is easy to operate is proposed. Summary of the Invention

[0007] Furthermore, the transmission type blade moving assembly also includes a pipeline valve and a return pipe. One side of the surface of the transmission box is connected to the return pipe through the pipeline valve, and the end of the return pipe is connected to the water tank.

[0008] Furthermore, the lifting plate is slidably connected to the surface of the slicer body through a motor screw or an electric telescopic rod, and the lifting plate has a U-shaped structure.

[0009] Furthermore, the bottom of the spring telescopic rod piston is fixedly connected to the top of the lifting plate, and the top structural shape of the spring telescopic rod piston is adapted to the internal structural shape of the rotating cylinder.

[0010] Furthermore, a blade assembly is fixed on the surface of the blade base, and the blade assembly includes a driving motor, a rotating screw and a movable sleeve base. The output end of the driving motor is connected to the rotating screw, and the outer wall of the rotating screw is provided with a movable sleeve base.

[0011] Furthermore, one end of the rotating screw rod away from the driving motor is rotatably connected to the blade base, and the rotating screw rod is arranged horizontally.

[0012] Furthermore, the blade assembly also includes a blade fixing seat, the outer sleeve of the movable sleeve base is provided with the blade fixing seat, and the blade fixing seat is arranged in an inclined shape, and the blade fixing seat is slidably connected to the blade base.

[0016] The present invention provides a device for rapidly preparing pathological sections that is easy to operate and has the following beneficial effects:

[0017] 1. This easy-to-operate rapid pathology section preparation device utilizes the principle that a lifting plate clamps a paraffin block and performs repeated lifting and lowering movements to inject a quantitative flow medium into the interior of the rotating cylinder each time the plate descends, and then injects a quantitative flow medium into the transmission box when the paraffin block rises, so that the blade body extends a fixed distance with each rise and fall of the paraffin block, thereby achieving rapid slicing of the paraffin block while ensuring the uniformity of each slice. In addition, the elastic expansion and contraction of the spring telescopic rod piston is utilized to cause a delay effect when the blade body moves each time the lifting plate rises, thereby preventing the blade body from extending as the paraffin block rises from the bottom, thereby preventing interference with the movement of the paraffin block.

[0018] 2. This easy-to-operate device for rapid preparation of pathological sections uses a spacer bar to divide the surface of the blade body into several slicing areas. After a paraffin block has been sliced ​​in one slicing area, the drive motor drives the rotating screw to rotate to move the blade body, so that the next slicing area of ​​the blade body replaces the used slicing area. As a result, the blade body will not use the same area for slicing each time it slices a paraffin block, thereby preventing the risk of cross-contamination of the slices. The spacer bar separates each slicing area to prevent the spread of slicing residues on the surface of each slicing area. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0026] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a device for quickly preparing pathological slices that is easy to operate, comprising a slicer body 1 and a transmission type blade moving assembly 5, a lifting plate 2 is provided on the front end surface of the slicer body 1, and a threaded rod 3 is threadedly connected to one side of the lifting plate 2, and a clamping plate 4 is rotatably connected to one end of the threaded rod 3, and the transmission type blade moving assembly 5 is fixed to the top of the slicer body 1, and the transmission type blade moving assembly 5 comprises a rotating cylinder 501, a first one-way valve 502, a first transmission pipe 503, a second one-way valve 504, a second transmission pipe 505, a transmission box 506, a telescopic piston 507, a blade base 508 and a spring telescopic rod piston 509, the back side of the rotating cylinder 501 is connected to the first transmission pipe 503 through the first one-way valve 502, and the end of the first transmission pipe 503 is connected to the water tank, and the side of the rotating cylinder 501 is connected to the second one-way valve 504. The valve 504 is connected to a second transmission pipe 505, and the end of the second transmission pipe 505 is connected to a transmission box 506. A telescopic piston 507 is provided on the back of the transmission box 506, and the end of the telescopic piston 507 is connected to a blade base 508. A spring telescopic rod piston 509 is provided at the bottom of the rotating cylinder 501. The transmission blade moving assembly 5 also includes a pipeline valve 510 and a return pipe 511. One side of the surface of the transmission box 506 is connected to the return pipe 511 through the pipeline valve 510, and the end of the return pipe 511 is connected to a water tank. The lifting plate 2 is slidably connected to the surface of the slicer body 1 through a motor screw or an electric telescopic rod, and the lifting plate 2 has a U-shaped structure. The bottom of the spring telescopic rod piston 509 is fixedly connected to the top of the lifting plate 2, and the top structural shape of the spring telescopic rod piston 509 is adapted to the internal structural shape of the rotating cylinder 501.

[0027] The specific operation is as follows: the paraffin block is placed on the inner side of the lifting plate 2, and the clamping plate 4 is made to slide along the surface of the lifting plate 2 by rotating the threaded rod 3, so that the lifting plate 2 cooperates with the lifting plate 2 to clamp the paraffin block, and the end surface of the paraffin block protrudes from the end surface of the clamping plate 4 and the lifting plate 2 to receive the slices, and the lifting plate 2 is lifted and lowered by the driving source inside the slicer body 1, such as the motor screw or the electric push rod. When the lifting plate 2 descends, the spring telescopic rod piston 509 itself first extends downward from the contracted state. When it extends to the limit, the spring telescopic rod piston 509 descends as a whole due to the continued descent of the lifting plate 2. At this time, the first one-way valve 502 is opened and the second one-way valve 504 is closed, so that the flow in the water tank The medium is injected into the rotating cylinder 501 along the first transmission pipe 503. When the lifting plate 2 is lifted with the paraffin block, the spring telescopic rod piston 509 first changes from an extended state to a retracted state. When it is retracted to the limit, the spring telescopic rod piston 509 rises as a whole. At this time, the first one-way valve 502 is closed and the second one-way valve 504 is opened. At this time, the flowing medium inside the rotating cylinder 501 enters the transmission box 506 along the second transmission pipe 505, causing the telescopic piston 507 to extend with the blade base 508, thereby making the blade body 605 close to the paraffin block at a fixed distance. The above operation is repeated continuously. Since the blade body 605 moves a fixed distance each time, the paraffin block can be evenly cut into several thin slices.

[0028] When the fluid medium is injected into or discharged from the rotating cylinder 501, it is after the spring telescopic rod piston 509 is fully extended or fully retracted. For example, after the paraffin block rises to a height exceeding the height of the blade body 605, the spring telescopic rod piston 509 is fully retracted, and then the fluid medium is injected into the transmission box 506. At this time, the blade body 605 is extended, thereby preventing the blade body 605 from extending as the paraffin block rises from the bottom, thereby preventing the paraffin block from interfering with the movement of the paraffin block.

[0029] After slicing is completed, the pipeline valve 510 is opened, allowing the fluid inside the transmission box 506 to return to the water tank through the return pipe 511. At this time, the telescopic piston 507 and the blade base 508 carrying the blade body 605 naturally retract and return to their original position for the next use.

[0030] Based on the above description, the present invention utilizes the principle that the lifting plate 2 clamps the paraffin block for repeated lifting and lowering movements to inject a quantitative flow medium into the interior of the rotating cylinder 501 each time it descends, and injects a quantitative amount of the flow medium inside the rotating cylinder 501 into the transmission box 506 when the paraffin block rises, so that the blade body 605 extends a fixed distance adapted to its adaptation with each lifting and lowering of the paraffin block, thereby achieving rapid slicing of the paraffin block while ensuring the uniformity of each slice, and utilizing the elastic expansion and contraction of the spring telescopic rod piston 509 itself, so that the blade body 605 will produce a delay effect each time it moves with the lifting plate 2, so as to avoid the blade body 605 extending as the paraffin block rises from the bottom, thereby interfering with the movement of the paraffin block.

[0031] like Figure 1-Figure 5 As shown, a blade assembly 6 is fixed on the surface of the blade base 508, and the blade assembly 6 includes a driving motor 601, a rotating screw 602 and a movable sleeve base 603. The output end of the driving motor 601 is connected to the rotating screw 602, and the outer wall of the rotating screw 602 is provided with a movable sleeve base 603. The end of the rotating screw 602 away from the driving motor 601 is rotatably connected to the blade base 508, and the rotating screw 602 is arranged horizontally. The blade assembly 6 also includes a blade fixing seat 604, and the outer sleeve of the movable sleeve base 603 is provided. A blade fixing seat 604 is provided, and the blade fixing seat 604 is arranged in an inclined shape, and the blade fixing seat 604 is slidably connected to the blade base 508. The blade assembly 6 also includes a blade body 605. The blade body 605 is inserted into the interior of the blade fixing seat 604. The blade assembly 6 also includes a spacer 606. The spacer bars 606 are evenly distributed on the surface of the blade body 605. The bottom end of the spacer bar 606 is fixedly connected to the surface of the blade fixing seat 604, and the top of the spacer bar 606 is located at the cutting edge of the blade body 605.

[0032] The specific operation is as follows: each time the blade base 508 moves with the blade body 605, the displacement sensor inside it senses the movement, and the driving motor 601 drives the rotating screw 602 to rotate so that the movable sleeve base 603 on its surface carries the blade fixing seat 604 and the blade body 605 to move a preset distance. The preset distance is the distance between two adjacent spacer bars 606. The spacer bars 606 divide the surface of the blade body 605 into several slicing areas. After the paraffin block has been sliced ​​in a slicing area, the driving motor 601 drives the rotating screw 602 to rotate to move the blade body 605, so that the next slicing area of ​​the blade body 605 replaces the used slicing area. As a result, each time the blade body 605 slices the paraffin block, the same area will not be used for slicing, so as to prevent the risk of cross-contamination of the cut slices. The spacer bars 606 separate each slicing area to prevent the slicing residues on the surface of each slicing area from spreading, so that there is no need to frequently replace the blade body 605 to ensure the cleanliness of each slice.

[0033] In summary, when the easy-to-operate device for rapid preparation of pathological slices is used, the paraffin block is first placed on the inner side of the lifting plate 2, and the clamping plate 4 is made to slide along the surface of the lifting plate 2 by rotating the threaded rod 3, so that the lifting plate 2 cooperates with the lifting plate 2 to clamp the paraffin block, and the lifting plate 2 is lifted and lowered by a driving source such as a motor screw or an electric push rod inside the slicer body 1. When the lifting plate 2 descends, the spring telescopic rod piston 509 itself first extends downward from a contracted state. When it extends to the limit, the spring telescopic rod piston 509 descends as a whole due to the continued descent of the lifting plate 2. At this time, the first one-way valve 502 is opened and the second one-way valve 504 is closed, so that the flowing medium in the water tank moves along the first one-way valve 502. The transmission tube 503 is injected into the interior of the rotating cylinder 501. When the lifting plate 2 is lifted with the paraffin block, the spring telescopic rod piston 509 first changes from an extended state to a retracted state. When it is retracted to the limit, the spring telescopic rod piston 509 rises as a whole. At this time, the first one-way valve 502 is closed and the second one-way valve 504 is opened. At this time, the fluid inside the rotating cylinder 501 enters the transmission box 506 along the second transmission tube 505, causing the telescopic piston 507 to extend with the blade base 508, thereby making the blade body 605 close to the paraffin block at a fixed distance. The above operation is repeated continuously. Since the blade body 605 moves a fixed distance each time, the paraffin block can be evenly cut into several thin slices.

[0034] When the fluid medium is injected into or discharged from the rotating cylinder 501, it is after the spring telescopic rod piston 509 is fully extended or fully retracted. For example, after the paraffin block rises to a height exceeding the height of the blade body 605, the spring telescopic rod piston 509 is fully retracted, and then the fluid medium is injected into the transmission box 506. At this time, the blade body 605 is extended, thereby preventing the blade body 605 from extending as the paraffin block rises from the bottom, thereby preventing the paraffin block from interfering with the movement of the paraffin block.

[0035] Each time the blade base 508 moves with the blade body 605, the displacement sensor inside it senses the movement, and the driving motor 601 drives the rotating screw 602 to rotate so that the movable sleeve base 603 on its surface carries the blade fixing seat 604 and the blade body 605 to move a preset distance. The preset distance is the distance between two adjacent spacer bars 606. The spacer bars 606 divide the surface of the blade body 605 into several slicing areas. After the paraffin block has been sliced ​​in a slicing area, the driving motor 601 drives the rotating screw 602 to rotate to move the blade body 605, so that the next slicing area of ​​the blade body 605 replaces the used slicing area, thereby ensuring that the same area will not be used for slicing each time the blade body 605 slices the paraffin block.

Many modifications and variations will be apparent to those skilled in the art.
