Description

Technical Field

[0001] This utility model relates to the field of pathological cutting, specifically a pathological tissue sampling and slicing device. Background Technology

[0002] Pathological tissue sectioning involves taking a lesion of a certain size and preparing it into a pathological section using histological methods. Typically, the lesion tissue is embedded in a paraffin block, sliced ​​into thin sections using a microtome, stained with hematoxylin and eosin (HE), and then further examined under a microscope to observe the lesion's development and progression, ultimately leading to a pathological diagnosis. A slide preparation apparatus is required for this process.

[0003] A pathological tissue sampling and sectioning device with announcement number CN218725411U, through the cooperative design of the operating table and the blade holder, when a pathological block needs to be sectioned to a specific thickness, the handwheel is used to turn the screw, thereby controlling the threaded block to drive the blade holder to move, adjusting the blade holder to the same scale position as the required section thickness, and sectioning the pathological block. After each sectioning, according to the scale position, the handwheel is used to continue to adjust the position of the blade holder, thereby obtaining pathological sections of the same thickness.

[0004] However, there are some shortcomings in its use. Users need to visually observe the graduated grooves to confirm the distance the pathological block has moved. Prolonged visual observation can cause eye fatigue, leading to errors and reducing the quality of the sliced ​​pathological blocks. Furthermore, the fixing frame interferes with the movement of the scalpel holder during slicing, requiring frequent movement of the pathological block to the side of the fixing frame for slicing, thus limiting the practicality of the device. Therefore, a pathological tissue sampling and slicing device is proposed to address these problems. Utility Model Content

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a pathological tissue sampling and sectioning device. (Refer to...) Figure 1 and Figure 4 A pathological tissue sampling and slicing device includes a base plate 1; a support base 2 is fixedly connected to the bottom of the base plate 1, a limiting mechanism 5 is provided on the surface of the base plate 1, and a slicing mechanism 3 is provided on the top of the base plate 1.

[0028] The slicing mechanism 3 includes a fixed plate 301 fixedly connected to the top of the base plate 1. A slow-speed cylinder 305 is mounted on the side of the fixed plate 301. A moving plate 304 is fixedly connected to the side of the slow-speed cylinder 305. A displacement sensor 303 is fixedly connected to the surface of the moving plate 304. A miniature cylinder 307 is mounted on the bottom of the moving plate 304. A cutting blade 306 is fixedly connected to the bottom of the miniature cylinder 307. A control plate 302 is fixedly connected to the surface of the fixed plate 301. The displacement sensor 303 is electrically connected to the control plate 302. Electrically connected to the micro cylinder 307 and the slow cylinder 305, the distance the cutting blade 306 moves can be monitored by the displacement sensor 303 and the information can be transmitted to the control board 302. When the set distance is reached, the control board 302 closes the slow cylinder 305 and starts the micro cylinder 307. The micro cylinder 307 drives the cutting blade 306 to move downward, thereby slicing the pathological block 506, making the slices of uniform thickness, thus improving the quality of the slices, avoiding manual operation, and improving the efficiency of slicing.

[0029] The limiting mechanism 5 includes a vertical plate 501 and a support plate 504 fixedly connected to the surface of the base plate 1. A drive motor 502 is installed on the side of the vertical plate 501, and a connecting plate 503 is fixedly connected to the output end of the drive motor 502.

[0030] Reference Figure 3 and Figure 4A connecting plate 503 is disposed on the side of a vertical plate 501 and is rotatably connected to the vertical plate 501. The bottom of the connecting plate 503 abuts against a support plate 504. A limit ring 5010 is fixedly connected to the bottom of the connecting plate 503. A threaded rod 509 is rotatably connected inside the limit ring 5010. The threads at both ends of the threaded rod 509 have opposite directions of rotation. A threaded sleeve 508 is threadedly connected to the outside of the threaded rod 509. A pressing plate 505 is fixedly connected to the top of the threaded sleeve 508. The pressing plate 505 is slidably connected to the connecting plate 503. The surface of plate 503 abuts against the pathological block 506, and the compression plate 505 abuts against the pathological block 506. The side end of the threaded rod 509 is fixedly connected to the turntable 507. The pathological block 506 can be compressed and fixed by the compression plate 505 to prevent the pathological block 506 from moving accidentally during slicing. At the same time, since the compression plate 505 is located on the side of the cutting blade 306, the compression plate 505 will not affect the movement of the cutting blade 306. After the slicing is completed, the connecting plate 503 is tilted, and the pathological slide falls into the collection box 4 for collection.

[0031] Reference Figure 1 and Figure 2 The cutting blade 306 is made of stainless steel and is triangular in shape. The cutting blade 306 is set on the top of the pathological block 506. The surface of the base plate 1 abuts against the collection box 4, which is set at the bottom of the connecting plate 503. The threaded rod 509 is made of stainless steel and is set on the side of the support plate 504.

[0032] Working principle: The pathological block 506 is placed on the surface of the connecting plate 503. Then, the turntable 507 is rotated, which in turn drives the threaded rod 509 to rotate. Through the threaded connection between the threaded rod 509 and the threaded sleeve 508, the extrusion plate 505 can be moved. The extrusion plate 505 abuts and limits the pathological block 506. Then, the slow-speed cylinder 305 drives the moving plate 304, displacement sensor 303, micro cylinder 307 and cutting blade 306 to move. The displacement sensor 303 monitors the distance the cutting blade 306 moves, and then the signal is transmitted. The information is transmitted to the control board 302, which stops the slow cylinder 305 from working. At the same time, the micro cylinder 307 drives the cutting blade 306 to move downward. The cutting blade 306 can slice the pathological block 506. This cycle is repeated to cut the pathological block 506 into equidistant pathological slices. After the cutting is completed, all external electrical switches are turned off. Then the cutting blade 306 is moved to the top of the pathological block 506. Then the drive motor 502 drives the connecting plate 503 and the pathological slice to tilt, so that the pathological slice moves into the collection box 4.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
