Description

Technical Field

[0001] The utility model specifically relates to the technical field of microscopic tissue sections, in particular to a multifunctional tablet press for resin semi-thin sections. Background Art

[0002] Making resin semi-thin sections has become a common method for observing microstructures. However, during the sectioning process, the sections are prone to curling and being scrapped. Therefore, auxiliary tools are often needed to press the sections to prevent curling. After preparing the sections, the section transfer is also a critical step. Sharp instruments can easily puncture the sections, thereby reducing the quality of the sections. Therefore, it is extremely important to have special tools.

[0003] However, there are no dedicated tablet pressing and transferring tools on the current market, and the tools currently used include but are not limited to mascara pens, tweezers, copper rings, etc. In fact, all of the above tools have disadvantages to varying degrees. For example, the hair has low hardness and is difficult to press, the copper ring cannot be pressed well due to its wide force area, and the tweezers are too sharp and often pierce the resin. At the same time, the metal material is easy to poke the blade, thereby damaging the blade, causing scratches on the slice, reducing the service life and increasing operating costs. In the process of slice transfer, tweezers are often used to clamp the edge of the slice, but this may pierce the slice. It is essential to be equipped with dedicated tools for tablet pressing, slice transfer, and slice scooping, but this often requires multiple tools. Utility Model Content

[0023] like Figure 1-2 As shown, the utility model is a multifunctional tablet press for semi-thin sections of resin, comprising a handle 3, a tablet pressing tip 1 and a transfer tool, one end of the handle 3 is connected to the tablet pressing tip 1, the tablet pressing tip 1 gradually becomes thinner from the connection with the handle 3 to the needle tip of the tablet pressing tip 1, and a layer of flexible cushion layer 2 is wrapped on the surface of the needle tip, and the other end of the handle 3 is separately connected to a detachable transfer tool, and the transfer tool includes a tablet mover 5 and a tablet scooper 6.

[0024] The tablet pressing tip 1 is made of stainless steel, and the diameter of the tablet pressing tip 1 gradually decreases from 1.5 mm to 0.6 mm. The flexible cushion layer 2 on the needle tip surface is made of thin polypropylene plastic. The selected materials are all common materials, which are easy to obtain and process, and have low cost.

[0025] When slicing, the tablet pressing tip 1 is used to press the resin slice, and the thin polypropylene plastic wrapping can effectively prevent damage to the slice and avoid waste; it can also prevent damage to the slicing knife and cause greater losses; the tablet pressing tip 1 has a smaller contact area with the slice due to its reduced diameter, making it easier to press the slice and flatten the slice.

[0026] The handle 3 is made of stainless steel, and the diameter of the handle 3 is 2 mm. The length of the handle 3 is 1.5 times the length of the tabletting tip 1. The handle 3 is convenient for the user to grasp and use. The connecting end of the handle 3 and the transfer tool is a concave cross head opening 4. The connection between the handle 3 and the concave cross head opening 4 is hollow. The hollow is used to install the concave cross head opening 4, and its depth is 3 mm. The concave cross head opening 4 is a separate part. The concave cross head opening 4 is convenient for the transfer tool to connect with the handle 3. The rest of the handle 3 is solid.

[0027] The transfer tool includes a film mover 5 and a film scooping tool 6. The film mover 5 and the film scooping tool 6 can only be used after being connected to the handle 3 separately and cannot be used at the same time. The two can be disassembled and used according to different needs.

[0028] One end of the slide mover 5 is an outwardly convex crosshead, and the other end is connected to a stainless steel disc with a thickness of 1 mm. After the slices are prepared, use the end of the disc to gently shovel 1 / 2-2 / 3 of the slices onto the disc, and then transfer them to the glass slide. The surface of the disc is smooth and flat, which can fully fit the slices to prevent the slices from falling during the transfer process.

[0029] The slice scoop 6 is made of stainless steel, one end of which is a convex cross head and the other end is connected to a ring. The inner diameter of the ring is 2.5 mm and the outer diameter is 3 mm. There are several small holes evenly distributed on the ring. When the slices immersed in the liquid need to be transferred, the ring of the slice scoop 6 is convenient for positioning and scooping. At the same time, the small holes on the ring make full use of the surface tension of water to protect the slices from damage during the scooping and moving process until they are safely transferred to the slide.

[0030] The convex cross heads of the film mover 5 and the film scooping tool 6 are inserted into the concave cross head opening 4 of the handle 3 and then rotated and clamped. This installation method is convenient for quick disassembly and assembly, and the overall operation difficulty is low.

[0031] The method of using a multifunctional tablet press for semi-thin sections of resin in this embodiment is as follows:

[0032] First, cut the sample with a hand-cranked resin slicer, turn the handwheel with your right hand to make the sample gradually contact and fit the blade, and then start to cut out partial slices. When cutting out partial slices, pinch the handle 3 and use the tablet pressing tip 1 to press the slice, continue to turn the handwheel with your right hand, and continue to press the slice with the tablet pressing tip 1 with your left hand, and keep it consistent with the rotation speed of the right hand until the slice is completely cut out.

[0033] Then use the slide mover 5 on the other side of the multifunctional slide press to scoop and move the slices, and use the disc of the slide mover 5 to gently scoop the slices so that 1 / 2-2 / 3 of the slices are located on the disc of the slide mover 5, and then transfer the slices to the glass slide with water droplets on it; if a water tank is needed to spread the slices, transfer the slices to the water tank, and then remove the slide mover 5, install the slice scooper 6, and use the slice scooper 6 to scoop up the slices, use the surface tension of water to protect the slices from damage, and safely transfer them to the glass slide.

[0034] The above embodiments are only for illustrating the technical idea of ​​the present utility model, and cannot be used to limit the protection scope of the present utility model. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present utility model shall fall within the protection scope of the present utility model.
