[0002] A Chinese patent with the publication number of CN220437794U discloses a convenient pathological sampling device, which includes a placement plate. On both sides of the top end of the placement plate, there are support plates. Between the support plates, there is a fixing plate. At the bottom end of the fixing plate, there is an electric telescopic rod. At the telescopic end of the electric telescopic rod, there is a knife plate. At the bottom end of the knife plate, there is at least one cutting knife. On the placement plate, there is a sampling groove, and clamping and fixing plate structures are arranged on both sides of the sampling groove.

[0032] The following will, in conjunction with the drawings and embodiments, elaborate on the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0033] Please refer to Figures 1 to 7As shown in the figure, an embodiment of the present utility model provides a pathological sampling device, which includes a base 1. A reverse L-shaped plate 2 is fixedly welded to the top of the base 1. An electric push rod 3 is fixedly installed at the top of the reverse L-shaped plate 2. The lower end of the piston rod of the electric push rod 3 slidably penetrates through the upper end of the reverse L-shaped plate 2 and is detachably installed with a mounting plate 5. A plurality of cutting knives 8 are fixedly installed at the bottom of the mounting plate 5. A pressing plate 6 is installed at the bottom of the mounting plate 5 through a telescopic rod 7. A first spring 701 is sleeved on the telescopic rod 7. The upper end of the first spring 701 abuts against the bottom of the mounting plate 5, and the lower end of the first spring 701 presses on the top of the pressing plate 6. Among them, the telescopic rod 7 is composed of a sleeve and a T-shaped rod. The upper end of the T-shaped rod is slidably arranged in the sleeve, and the lower end of the T-shaped rod passes through the lower end of the sleeve. A plurality of knife holes 601 are opened on the pressing plate 6. When cutting a pathological sample, the lower end of the cutting knife 8 can penetrate through the knife holes 601, and the opening of the knife holes 601 gradually decreases from top to bottom. By providing the knife holes 601, after the cutting knife 8 cuts the pathological sample, it can be withdrawn from the knife holes 601, and thus the sections adhered to the cutting knife 8 are blocked by the knife holes 601 and fall off, avoiding the phenomenon of adhered section samples on the cutting knife 8. A sampling trough body 9 for storing the pathological sample to be cut is detachably installed on the top of the base 1 through a disassembly and assembly mechanism. In this embodiment, the disassembly and assembly mechanism includes a plug 901 and a pull rod 11. The plug 901 is fixedly connected to the bottom of the sampling trough body 9. A locking hole 902 is opened on one side of the plug 901. A limiting groove 102 is opened on the top of the base 1. The locking hole 902 is inserted into the limiting groove 102. An assembly groove 101 is opened inside the base 1. The assembly groove 101 is communicated with the limiting groove 102. One end of the pull rod 11 is slidably arranged in the assembly groove 101. The end of the pull rod 11 far from the assembly groove 101 slidably penetrates through the inside of the base 1 and is fixedly connected with a handle 10. A plug 13 is slidably arranged inside the assembly groove 101. The plug 13 is fixedly connected with one end of the pull rod 11. A second spring 12 is sleeved on the pull rod 11. One end of the second spring 12 abuts against one end of the assembly groove 101, and the other end of the second spring 12 abuts against one end of the plug 13. The plug 13 can be inserted into the locking hole 902.

[0034] Working principle: When in use, first pull the handle 10 outwards, retract the plug 13 into the assembly groove 101, then insert the insertion block 901 on the material taking groove body 9 into the limit groove 102. At this time, release the handle 10, and the plug 13 is inserted into the locking hole 902 under the elastic force of the second spring 12, then the installation of the material taking groove body 9 can be completed. Then, place the pathological sample to be cut into the material taking groove body 9, and then control the piston rod of the electric push rod 3 to quickly extend, so that the bottom of the pressing plate 6 presses on the pathological sample to be cut to prevent it from shifting during cutting. As the piston rod of the electric push rod 3 continuously moves down quickly, the telescopic rod 7 shortens, and the first spring 701 is compressed. The lower end of the cutting knife 8 penetrates out of the knife hole 601 to quickly cut the pathological sample to be cut. Then, control the piston rod of the electric push rod 3 to retract. The cutting knife 8 first retracts from the knife hole 601, and the section adhered to the cutting knife 8 is blocked by the knife hole 601 and drops;

[0035] When it is necessary to disassemble and clean the material taking groove body 9, just pull the handle 10 outwards, retract the plug 13 into the assembly groove 101, and then lift the material taking groove body 9 upwards to complete the disassembly of the material taking groove body 9.

[0036] Specifically, the top of the mounting plate 5 is fixedly connected with a mounting sleeve 501. The mounting sleeve 501 is sleeved on the lower end of the piston rod of the electric push rod 3. A threaded hole 302 is opened at the lower end of the piston rod of the electric push rod 3. A handle screw 503 is rotatably mounted on the mounting sleeve 501. One end of the handle screw 503 can be threadedly fixed inside the threaded hole 302. By adopting the above setting, it is convenient to remove the mounting plate 5 from the electric push rod 3, so as to facilitate the subsequent cleaning and disinfection of the cutting knife 8 and the pressing plate 6.

[0037] Specifically, a positioning block 502 is fixedly connected to the inner wall of the mounting sleeve 501. A positioning groove 301 is opened at the lower end of the piston rod of the electric push rod 3. The positioning block 502 is inserted into the positioning groove 301. Through this setting, it is convenient to quickly align one end of the handle screw 503 with the threaded hole 302 and improve the installation efficiency.

[0038] Specifically, a control button 4 for controlling the extension and retraction of the piston rod of the electric push rod 3 is fixedly installed on the top of the inverted L-shaped plate 2. Through this setting, it is convenient to control the extension and retraction of the piston rod of the electric push rod 3.
