This utility model provides a medical laboratory sample slicing device, which employs the cooperation of a slicing concave stage, a moving plate, a sample positioning shell, and a uniform speed pushing mechanism. The sample is placed on an L-shaped tray and clamped and positioned by a clamping plate on the front side, then locked by a locking assembly.

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1 As shown, this utility model provides a medical laboratory sample slicing device, including a slicing platform 1, a control panel 2 at the rear end of the outer wall of the slicing platform 1, a base 10 fixedly connected to the bottom of the slicing platform 1, a moving plate 3 fixedly connected to the right side inside the slicing platform 1, a sample positioning shell 4 fixedly connected to the left side of the top of the moving plate 3, a semi-circular groove 401 opened at the left end of the sample positioning shell 4, a uniform speed pushing mechanism 5 at the right end of the slicing platform 1, and the left end of the outer wall of the uniform speed pushing mechanism 5 penetrating into the interior of the sample positioning shell 4, a slicing mechanism 6 at the outer wall of the slicing platform 1 near the semi-circular groove 401, and the bottom of the outer side of the slicing mechanism 6 penetrating into the top of the base 10, a scraping component 7 at the front side of the slicing platform 1 near the outer side of the slicing mechanism 6, an internally and externally penetrating discharge port 8 at the front end of the slicing platform 1 near the scraping component 7, and a guide ramp 9 fixedly connected to the rear side of the inner wall of the slicing platform 1 near the discharge port 8.

[0025] The system comprises a slicing platform 1, a control panel 2, a moving plate 3, a sample positioning shell 4, a uniform speed pushing mechanism 5, a slicing mechanism 6, a scraping component 7, a discharge port 8, a guide ramp 9, and a base 10. Through the coordinated operation of the uniform speed pushing mechanism 5 and the slicing mechanism 6, after the sample is clamped and fixed, the uniform speed pushing mechanism 5 is operated to push the sample out along the surface of the moving plate 3 at a uniform speed along the semi-circular groove 401 inside the sample positioning shell 4, allowing the slicing mechanism 6 to slice the sample, ensuring that the thickness of the sample slices remains uniform. During the slicing process, the scraping component 7 scrapes away any sample slices adhering to the slicing mechanism 6 to prevent adhesion.

[0026] like Figure 2 As shown, this utility model provides a technical solution for a medical laboratory sample slicing device: the uniform speed pushing mechanism 5 includes an electric telescopic rod 51, an L-shaped support plate 52, two clamping plates 53, two anti-slip pads 54, and a locking assembly 55. The output end of the electric telescopic rod 51 penetrates into the interior of the slicing recess 1 and is fixedly connected to the bottom of the L-shaped support plate 52 in the vertical direction. The outer walls of the two clamping plates 53 are respectively set on the front and rear sides of the transverse surface of the L-shaped support plate 52. The surfaces of the two anti-slip pads 54 are respectively fixedly connected to the opposite surfaces of the two clamping plates 53. The anti-slip pads 54 are provided to increase the friction between the clamping plates 53 and the sample, preventing the sample from shifting during slicing. One end of the rear clamping plate 53 is fixedly attached to the rear side of the inner wall of the L-shaped support plate 52 in the vertical direction. A movable groove 520 is provided on the top of the vertical side near the front of the clamping plate 53. A limiting groove 5201 is provided on the top of the horizontal surface of the L-shaped support plate 52 near the front of the clamping plate 53. A groove 301 is provided on the top of the movable plate 3. A slider 521 is fixedly connected to the bottom of the horizontal surface of the L-shaped support plate 52. The outer wall of the slider 521 is slidably connected to the inner wall of the groove 301. The limiting block 531 slides along the groove 301, which limits the movement trajectory of the L-shaped support plate 52 driven by the output end of the electric telescopic rod 51. A limiting block 531 is fixedly connected to the right end of the front clamping plate 53. The outer wall of the limiting block 531 is slidably connected to the inner wall of the limiting groove 5201. The limiting block 531 slides along the limiting groove 5201, which limits the movement direction of the front clamping plate 53.

[0027] like Figure 3As shown, this utility model provides a technical solution for a medical laboratory sample slide device: the locking component 55 includes a knob 551, a screw 552, and a rubber protrusion 553. The upper end of the screw 552 is fixedly connected to the middle of the knob 551, and the lower end of the screw 552 is fixedly connected to the top of the rubber protrusion 553. A locking block 532 is fixedly connected to the right end of the front clamping plate 53. The outer surface of the locking block 532 is set on the top of the moving groove 520, and a groove is opened in the middle of the locking block 532 to connect with the screw. A threaded hole 5320 that is compatible with and extends vertically is provided. The lower end of the outer wall of the screw 552 passes through the bottom of the threaded hole 5320 and is threadedly connected to it. A locking groove 5202 is provided on the top of the moving groove 520. The outer wall of the rubber protrusion 553 is engaged with the inner wall of the locking groove 5202. By rotating the screw 552, the rubber protrusion 553 is moved downward, and the rubber protrusion 553 is squeezed into the locking groove 5202, which facilitates the locking effect of the front clamping plate 53.

[0028] like Figure 4 As shown, this utility model provides a technical solution for a medical laboratory sample slicing device: the slicing mechanism 6 includes a rotary motor 61, a connecting roller 62, a circular cutter 63, a nut 64, and a rubber ring 65. The output shaft of the rotary motor 61 is fixedly connected to the lower end of the connecting roller 62. A threaded groove 620 is provided on the top of the outer wall of the connecting roller 62. A through-hole 630 is provided in the middle of the circular cutter 63. An arc-shaped groove 631 is provided on the outer wall of the circular cutter 63 near the through-hole 630. The inner wall of the rubber ring 65 is fixedly connected to... The outer wall of the connecting roller 62 is pressed against the surface of the rubber ring block 65, further increasing the frictional force of the connection between the circular cutter 63 and the outer wall of the connecting roller 62. The inner wall of the connecting roller 62 is sleeved with the inner wall of the insertion hole 630. The upper surface of the rubber ring block 65 overlaps with the lower surface of the circular cutter 63. The inner wall of the nut 64 is threadedly connected to the threaded groove 620 on the connecting roller 62. The bottom of the rotary motor 61 is fixedly connected to the top of the base 10. The nut 64 rotates along the threaded groove 620 on the connecting roller 62, which facilitates the assembly and disassembly of the circular cutter 63.

[0029] like Figure 5 As shown, this utility model provides a technical solution for a medical laboratory sample slicing device: the scraping component 7 includes a scraper 71, a connecting block 72, and a fixing post 73. One end of the connecting block 72 is fixedly connected to one side of the outer wall of the scraper 71. The top of the fixing post 73 is fixedly connected to the bottom of the connecting block 72. The bottom of the fixing post 73 is fixedly connected to the inside of the slicing recess 1. One end of the outer wall of the scraper 71 overlaps with the outer wall of the circular blade 63. The scraper 71 scrapes the surface of the rotating circular blade 63 to prevent the sample after slicing from sticking to the circular blade 63.

[0030] The working principle of this medical laboratory sample slicing device will be explained in detail below.

[0031] like Figure 1-5 As shown, when using this device to perform slicing tests on samples obtained in a hospital laboratory, firstly, the sample longer than the L-shaped tray 52 is placed on the L-shaped tray 52. ​​Then, according to the width of the sample, the front clamping plate 53 is slid along the limiting groove 5201 via the limiting block 531 to clamp and position the sample surface. Then, by rotating the knob 551 downwards, the rubber protrusion 553 is pressed into the locking groove 5202 for fixation, thereby locking the front clamping plate 53 to prevent displacement. Then, the electric telescopic rod 51 and the rotary motor 61 are activated. The output end of the electric telescopic rod 51 drives the L-shaped tray 52 to move to the left at a uniform speed, and the limiting block 531 slides along the groove 301, so that the sample is positioned along the sample positioning shell 4. Remove the semi-circular groove 401. The output shaft of the rotary motor 61 drives the circular cutter 63 to rotate through the connecting roller 62. The high-speed rotating circular cutter 63 slices the sample through the arc groove 631. The scraper 71 scrapes off the sliced ​​sample adhering to the outer wall of the circular cutter 63. The sliced ​​sample slides out from the discharge port 8 through the guide ramp 9. After the circular cutter 63 has been used for a long time, the nut 64 can be unscrewed along the threaded groove 620. A new circular cutter 63 can be put on the connecting roller 62 through the insertion hole 630. Then, the nut 64 is rotated down along the threaded groove 620 to the upper surface of the circular cutter 63. This causes the lower surface of the circular cutter 63 to press and adhere to the surface of the rubber ring block 65, increasing the friction of the connection.

[0032] The specific types and structures of the electric telescopic pole and rotary motor used are all existing products, as are the specific circuit connection structure and control relationship between the control panel and the electric telescopic pole and rotary motor. These will not be elaborated upon here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
