Description

Technical Field

[0001] This utility model relates to the technical field of sampling devices, and in particular to a pathological slide sampling device. Background Technology

[0002] A pathological section sampling device is a specialized tool used to obtain tissue samples and prepare them into pathological sections. Its core function is to cut paraffin-embedded tissue blocks to generate thin sections of uniform thickness for microscopic observation.

[0003] When using the pathological section sampling device, the fixed and dehydrated tissue sample is embedded in paraffin or freezing medium. Then, the paraffin containing the sample tissue is fixed on the microtome, and the paraffin block containing the tissue is cut into thin slices of uniform thickness through the cutting mechanism.

[0004] When using the pathological section sampling device, the paraffin itself is quite slippery, and the vibration generated during sectioning can cause the paraffin block to slightly slide or shift on the mounting base. This results in uneven thickness or even breakage of the sections, especially when cutting thin sections or cutting quickly. Furthermore, the surface of the paraffin is not smooth, so it is necessary to fix the paraffin on the mounting base before sectioning and repeatedly turn the handwheel to cut off the uneven areas, which is quite troublesome. Utility Model Content

[0005] The purpose of this invention is to provide a pathological slide sampling device to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A pathological slide sampling device includes a sampling device body, a rotating wheel rotatably connected to one side of the sampling device body, a movable seat slidably connected to the front of the sampling device body, a controller mounted on the front of the sampling device body, a slicing blade provided on the front of the sampling device body, a mounting box fixedly connected to the front of the movable seat, a fixing component provided inside the mounting box, the fixing component including a knob, a worm gear fixedly connected to one end of the knob, a worm wheel meshing with the surface of the worm gear, a transmission rod fixedly connected to the bottom of the worm wheel, a gear fixedly connected to the bottom of the transmission rod, a strip tooth meshing with both sides of the gear, a connecting rod fixedly connected to one side of the strip tooth, and a clamping plate fixedly connected to the bottom of the connecting rod.

[0008] In some embodiments, the bottom of the mounting box is provided with a sliding groove, which is slidably connected to the connecting rod.

[0009] In some embodiments, the inner side of the clamp is provided with anti-slip texture, which is a horizontally arranged raised structure.

[0010] In some embodiments, the back of the fixing component is provided with a slicing component, the slicing component includes a motor, the motor is fixedly connected inside the mounting box, the output end of the motor is fixedly connected with a first conical tooth, the surface of the first conical tooth is meshed with a second conical tooth, the bottom of the second conical tooth is fixedly connected with a lead screw, the surface of the lead screw is threaded with a buckle plate, and the bottom of the mounting box is fixedly connected with a cutter.

[0011] In some embodiments, a connecting block is fixedly connected to the front of the movable seat, and the connecting block is slidably connected to the back of the buckle plate.

[0012] In some embodiments, a collection box is fixedly connected to the front of the sampling device body, the top of the collection box is provided with a leakage hole, a sludge collection box is slidably connected inside the collection box, and a handle is fixedly connected to the front of the sludge collection box.

[0013] In some embodiments, a limiting block is provided at the bottom of the lead screw.

[0014] In some embodiments, the cutting edge of the cutter facing the clamping plate has a horizontal straight structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (i) The operator turns the knob, which, through the transmission components such as worm gears and gears, causes the clamping plates on both sides to move synchronously to clamp or release the sample. The bidirectional symmetrical clamping ensures that the sample is subjected to uniform force, prevents tilting and displacement, ensures the stability of the slice, and allows the clamping plate spacing to be adjusted to accommodate samples of different shapes and sizes.

[0017] (ii) When the surface of the paraffin is irregular and needs to be trimmed, place it between the cutter and the clip plate, press the paraffin down and start the motor. The screw is driven to rotate through the conical gear transmission, so that the clip plate moves in a straight line along the axis. The upward-moving clip plate works with the cutter to cut the paraffin, which can effectively trim the local protrusions or depressions of the paraffin and meet the requirements of pathological sections.

[0026] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Given that in current technology, when using pathological slide sampling devices, the paraffin itself is slippery, and the vibration generated during slicing causes the paraffin block to slightly slide or shift on the mounting base, resulting in uneven slice thickness or even breakage. This problem is more likely to occur when slicing thin slices or slicing quickly. Furthermore, the surface of the paraffin is not smooth, so it is necessary to fix the paraffin on the mounting base before slicing and repeatedly turn the handwheel to cut off the uneven areas, which is very troublesome.

[0029] like Figure 1-6 As shown, this utility model embodiment provides a pathological slide sampling device, including a sampling device body 1. A rotating wheel 101 is rotatably connected to one side of the sampling device body 1. A movable seat 102 is slidably connected to the front of the sampling device body 1. A controller 103 is installed on the front of the sampling device body 1. A slicing blade 104 is provided on the front of the sampling device body 1. A mounting box 3 is fixedly connected to the front of the movable seat 102. A fixing component 4 is provided inside the mounting box 3. The fixing component 4 includes a knob 401. A worm gear 402 is fixedly connected to one end of the knob 401. A worm wheel 403 is meshed with the surface of the worm gear 402. A transmission rod 404 is fixedly connected to the bottom of the worm wheel 403. A gear 405 is fixedly connected to the bottom of the transmission rod 404. A strip tooth 406 is meshed with both sides of the gear 405. A connecting rod 407 is fixedly connected to one side of the strip tooth 406. A clamping plate 408 is fixedly connected to the bottom of the connecting rod 407.

[0030] The rotating wheel 101 drives the movable seat 102 to slide along the front of the sampling device body 1 by manual rotation. The controller 103 controls the operating parameters of the entire device, while the slicer 104 performs slicing operations on the sample. The controller 103 (model HHQ-3658) is used for this purpose.

[0031] When it is necessary to fix the sample to be sliced, the operator turns knob 401, which drives worm gear 402 to rotate. Worm gear 402 meshes with worm wheel 403, causing worm wheel 403 to rotate. Worm wheel 403 drives transmission rod 404 to rotate, which in turn drives gear 405 to rotate. Gear 405 meshes with the strip teeth 406 on both sides, causing the strip teeth 406 to move. The strip teeth 406 drive connecting rod 407 to slide within slide groove 301, and connecting rod 407 drives clamping plate 408 to move, thereby clamping or releasing the sample. Gear 405 engages with the strip teeth 406 on both sides. When gear 405 rotates, it simultaneously drives the strip teeth 406 on both sides to move, thereby causing the connecting rods 407 and clamping plates 408 on both sides to move synchronously. This bidirectional symmetrical clamping method ensures that the sample is subjected to uniform and symmetrical clamping force in the horizontal direction, avoiding tilting or displacement of the sample due to uneven force, and ensuring the stability of the sample during slicing. Furthermore, the operator can precisely control the moving distance of clamping plates 408 by rotating knob 401 at different angles, thereby adjusting the spacing between clamping plates 408. This allows the device to adapt to samples of different shapes and sizes.

[0032] Furthermore, the bottom of the mounting box 3 is provided with a sliding groove 301, which is slidably connected to the connecting rod 407.

[0033] During the movement of the connecting rod 407, its bottom slides within the slide groove 301. The slide groove 301 guides the movement of the connecting rod 407, ensuring that the connecting rod 407 can only move in a straight line along the direction of the slide groove 301.

[0034] Furthermore, the inner side of the clamp 408 is provided with anti-slip texture, which is a horizontally arranged raised structure.

[0035] When the clamp 408 clamps the sample, the anti-slip texture on the inner side of the clamp 408 comes into contact with the sample surface, increasing the friction between the clamp 408 and the sample.

[0036] Furthermore, a slicing assembly 5 is provided on the back of the fixing assembly 4. The slicing assembly 5 includes a motor 501. The motor 501 is fixedly connected inside the mounting box 3. A first conical tooth 502 is fixedly connected to the output end of the motor 501. A second conical tooth 503 is meshed with the surface of the first conical tooth 502. A lead screw 504 is fixedly connected to the bottom of the second conical tooth 503. A buckle plate 505 is threadedly connected to the surface of the lead screw 504. A cutter 506 is fixedly connected to the bottom of the mounting box 3.

[0037] When the surface of the paraffin wax is irregular and needs to be trimmed, place the paraffin wax between the cutter 506 and the retaining plate 505, hold the paraffin wax with one hand to prevent it from shaking during cutting, and then start the motor 501. The output end of the motor 501 drives the first conical tooth 502 to rotate. The first conical tooth 502 meshes with the second conical tooth 503, causing the second conical tooth 503 to rotate. The second conical tooth 503 drives the lead screw 504 to rotate. The lead screw 504 is threadedly connected to the retaining plate 505. Under the rotation of the lead screw 504, the retaining plate 505 moves linearly along the axis of the lead screw 504. As the retaining plate 505 moves upward, the paraffin wax is gradually cut by the cutter 506. This setting allows the paraffin wax, whether locally protruding or concave, to be effectively trimmed by the sectioning component 5, ensuring that the trimmed paraffin wax meets the requirements of pathological sections.

[0038] Furthermore, a connecting block 1021 is fixedly connected to the front of the movable seat 102. The connecting block 1021 is slidably connected to the back of the buckle plate 505. When the buckle plate 505 moves linearly under the drive of the lead screw 504, its back is slidably connected to the connecting block 1021. The connecting block 1021 provides support and guidance for the buckle plate 505, enabling the buckle plate 505 to smoothly drive the movable seat 102 to move.

[0039] Furthermore, a collection box 2 is fixedly connected to the front of the sampling device body 1, and a leakage hole 201 is provided on the top of the collection box 2. A sludge collection box 202 is slidably connected inside the collection box 2, and a handle 203 is fixedly connected to the front of the sludge collection box 202.

[0040] During the slicing process, the sample debris cut off falls into the collection box 2 through the drain hole 201. The sludge collection box 202 slides inside the collection box 2. When the sludge collection box 202 is full of debris, the operator can pull the sludge collection box 202 out of the collection box 2 through the handle 203 for cleaning. This can effectively collect the debris generated during the slicing process and keep the working environment clean.

[0041] Furthermore, a limiting block is provided at the bottom of the lead screw 504, which can restrict the axial movement of the lead screw 504.

[0042] Furthermore, the cutting edge of the cutter 506 facing the clamping plate 408 has a horizontal line structure, and the horizontal straight cutting edge of the cutter 506 is completely in contact with the paraffin surface, forming a flat cutting surface during cutting.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
