[0002] Tissue microtome machines are frequently used in the field of biological tissue sectioning. These precision instruments cut biological tissue samples into extremely thin sections (typically a few micrometers thick) and are widely used in pathology, biology, and medical research to observe the microscopic structure of cells and tissues under a microscope. The sections cut by a microtome are extremely thin and therefore highly susceptible to static electricity. Static electricity is invisible to the naked eye and is constantly generated, significantly affecting the efficiency and quality of sectioning. Utility Model Content

Detailed Implementation
[0033] like Figure 1 , Figure 2 As shown, the present invention provides an electrostatic eliminator for the medical industry, comprising a base plate 10, a vertical support 20, a horizontal support 30, and an ion generator 40. The base plate 10 can be used to place target instruments such as tissue slicers. The vertical support 20 is fixed to the base plate 10. The connecting end of the horizontal support 30 is fixed to the vertical support 20 and its height can be adjusted. The ion generator 40 is fixed to the cantilever end of the horizontal support 30.
[0034] The ion generator 40 includes a housing 41, a mounting base 42, a high-voltage generator, a stainless steel needle holder 43, a fan 44, a speed controller 45, a filter screen 46, a lighting lamp, and a lower screen cover 47.
[0035] The fixed base 42 is fixed to the horizontal support 30 and has two horizontally spaced out support arms;
[0036] The housing 41 is connected to one arm of the fixed base 42 by a bolt on each side, so that the housing 41 can rotate around the line connecting the two bolts to adjust the pitch angle of the housing 41.
[0037] The high-voltage generator is fixed to the housing 41, which is internal in this embodiment and therefore not shown in the figure.
[0038] The stainless steel needle holder 43 is fixed inside the housing 41. The housing 41 has openings at the top and bottom corresponding to the stainless steel needle holder 43. The ion needle electrode 431 of the stainless steel needle holder 43 faces the downward opening. The stainless steel needle holder 43 is connected to the high voltage generator. The high voltage generated by the high voltage generator can form a strong electric field around the ion needle electrode 431 on the stainless steel needle holder 43, causing nitrogen and oxygen molecules in the air to ionize and generate a large number of positive and negative ions.
[0039] The fan 44 is fixed inside the housing 41 and located above the stainless steel needle holder 43. It blows air from top to bottom, which can blow positive and negative ions toward the base plate 10 to form an ionization field area.
[0040] The speed regulator 45 is fixed on one side of the housing 41 and connected to the fan 44. It can adjust the speed of the fan 44 and control the air volume. It can adopt a stepless speed regulation structure or a gear speed regulation structure.
[0041] The filter screen 46 is fixed at the opening above the housing 41 to filter impurities in the air and ensure the purity of the air blown out by the fan 44.
[0042] The lighting lamp (not shown) is fixed on the housing 41 and is used to shine light towards the base plate 10 to illuminate the operating area;
[0043] The lower mesh cover 47 is fixed at the opening at the bottom of the housing 41 to prevent foreign objects from entering the housing 41;
[0044] The front side of the housing 41 is also provided with a wind speed indicator 48 and a fault alarm light 49. The wind speed indicator 48 is used to display the rotation speed of the fan 44, and the fault alarm light 49 can light up when the instrument malfunctions to display fault information.
[0045] like Figure 3 , Figure 4 As shown, the filter screen 46 is composed of a support frame 461, filter cotton 462, and a top cover 463; the support frame 461 is fixed to the housing 41, and the top cover 463 engages with the support frame 461 to clamp the filter cotton 462; the housing 41 is provided with four blind holes 411 around the perimeter of the filter screen 46 to cooperate with the pry plate 50 to pry open the top cover 463;
[0046] The pry bar 50 is a strip-shaped plate with a pry tongue 501 extending from its lower end. A support wing 502 is provided on the side of the lower end opposite to the pry tongue 501. When the filter cotton 462 needs to be replaced, the pry tongue 501 of the pry bar 50 is inserted into the blind hole 411, and then the upper end of the pry bar 50 is moved. Using the support wing 502 as a lever fulcrum, the pry tongue 501 is used to pry open the upper cover 463.
[0047] like Figure 5 , Figure 6As shown, the lower mesh cover 47 is equipped with a cleaning brush 51 for cleaning function. The cleaning brush 51 has a knob 511 located in the center and a cantilever 512 extending integrally outward from the knob 511. A brush 513 is fixed at the end of the cantilever 512. A fixing hole 471 is provided in the center of the lower mesh cover 47, and the knob 511 of the cleaning brush 51 is assembled in the fixing hole 471. One end of the knob 511 protruding from the lower mesh cover 47 forms an operating groove. When cleaning is required, a motor or manual handle can be used to connect with the operating groove of the knob 511 to drive the cantilever 512 and the brush 513 to rotate. The brush 513 can interfere with the ion needle electrode 431 of the stainless steel needle holder 43 to clean the dust accumulated on the surface of the ion needle electrode 431.
[0048] like Figure 7 , Figure 8 , Figure 9 As shown, the connecting end of the horizontal support 30 is fixed with a connecting block 32 by bolts. A T-shaped slider 33 (in this embodiment, four T-shaped sliders 33 are arranged) is installed on the connecting block 32 with fastening bolts 31. The T-shaped slider 33 is connected to the sliding groove 21 arranged vertically in the vertical support 20. The end of the fastening bolt 31 exposed on the connecting block 32 is a drive end that can be rotated to loosen or tighten with a wrench or screwdriver. When the fastening bolt 31 is loosened, there is a gap between the T-shaped slider 33 and the sliding groove 21, and the T-shaped slider 33 can slide up and down in the sliding groove 21 to adjust the height of the horizontal support 30. When the fastening bolt 31 is tightened, the T-shaped slider 33 is pressed against the sliding groove 21 to achieve locking.
[0049] like Figure 10 , Figure 11 As shown, a receiving space is formed on the rear side of the base plate 10 for the power cord 52 to pass through (the power cord 52 can be connected to the high voltage generator through the interior of the vertical bracket 20 and the horizontal bracket 30). A fixing bracket 53 is fixed on the side wall of the receiving space. The fixing bracket 53 is generally L-shaped and has a screw hole on one side for fixing to the side wall of the receiving space. Two pairs of limiting grooves 531 are formed on both sides of the other side. The power cord 52 passes through one side of the fixing bracket 53 and is fixed to the two pairs of limiting grooves 531 of the fixing bracket 53 with two cable ties 54, which can effectively prevent the power cord 52 from rotating, stretching or moving.
[0050] The static eliminator of this invention uses a blower 44 to blow ions into the slicer's operating area, which can effectively eliminate static electricity in the operating area.
