Description

Technical Field

[0001] This utility model belongs to the technical field of slicing devices, specifically relating to a slicing device for paraffin-embedded tissue blocks. Background Technology

[0002] Innovative drug development requires in-depth research into the mechanisms of action of drugs on target organs and tissues. Therefore, it necessitates the use of slicing devices to cut paraffin-embedded tissue blocks into thin sections, providing a foundation for subsequent observation. For example, in anticancer drug research, tumor tissue treated with the drug is embedded in paraffin. After slicing, staining can be used to observe cell apoptosis and morphological changes. Nucleic acids can also be extracted to analyze gene expression changes, clarifying the drug's targets and effects. This provides intuitive and precise data support for the safety and efficacy evaluation and optimization of innovative drugs, thus accelerating the new drug development process.

[0003] In the paraffin-embedded tissue sectioning process, which is widely used in current innovative drug research and development and pathological analysis, the paraffin debris generated during the operation of existing sectioning devices can be initially collected by the collection base. However, due to the adhesion characteristics of the debris to the inner wall of the base, operators need to manually scrape it with auxiliary tools such as brushes. This process requires repeated disassembly of the base components, increasing the risk of equipment damage, and therefore has significant limitations. Utility Model Content

[0004] The purpose of this invention is to provide a paraffin-embedded tissue block slicing device to solve the problem of difficult waste removal in existing slicing devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paraffin-embedded tissue block slicing device, comprising...

[0006] The body has a wax block holder that can move up and down back and forth on the front surface;

[0007] A material collection base is installed on the bottom front surface of the machine body;

[0008] The cutting component is installed inside the aggregate base and is positioned entirely below the wax block placement seat;

[0009] The material collection base is internally equipped with a collection component, which includes a collection part and a cleaning part, wherein:

[0010] The collecting component is embedded inside the material collection base, while the cleaning component is slidably disposed inside the collecting component.

[0011] Preferably, the collecting component includes a collection bin, the outer wall of which is fully fitted with the inner wall of the collection base, and handles are provided on both sides of the collection bin, which can be quickly and easily pulled out from the inside of the collection base.

[0012] Preferably, the bottom surface of the collection bin has a placement groove, and a bottom plate is provided inside the placement groove. The end of the handle extends through the placement groove and is fixedly connected to the bottom plate. The thickness of the bottom plate is equal to the inner depth of the placement groove. When it is necessary to clean the chips collected inside the collection bin, first pull the handle upward, and then pull the collection bin out from the collection base. Then, stop holding one of the handles, and the handle at that point will descend under gravity, causing the bottom plate to separate from the placement groove. Then, hold the bottom plate and flip the entire collection bin over to realize the dumping of the collection bin. Alternatively, the collection bin can be shaken back and forth by the bottom plate to achieve efficient material discharge.

[0013] Preferably, the front and rear surfaces inside the collection bin are both fixed with slide rails, and a scraper is slidably arranged on the inner side of the slide rails. During slicing, the main chips are concentrated in the middle position of the collection bin. When the chips in the middle position are high, the chips can be guided to the sides by moving the scraper back and forth. The scraper has an opening at its end, and the inner wall of the opening is recessed outward. The upper and lower end faces of the slide rail are formed with grooves to fit the recess, thereby realizing the sliding connection between the scraper and the slide rail.

[0014] Preferably, it also includes a knife holder, and the inside of the material collection base is formed with an integral placement platform, and one end of the material collection bin has a concave portion that partially wraps around the placement platform; the knife holder is installed at the top of the placement platform.

[0015] Preferably, the cutting component includes a blade holder positioned directly below the wax block holder. A blade is mounted on top of the blade holder, positioned in front of the wax block holder. During slicing, paraffin wax is placed on the wax block holder, and then a handwheel is rotated to move the wax block holder up and down, causing the paraffin wax to contact the blade and be cut into slices. This working principle is existing technology and will not be described further here.

[0016] Preferably, a handwheel is also installed on the outside of the machine body. The handwheel is connected to the wax block placement seat for transmission. The reciprocating lifting and lowering of the wax block placement seat is realized by rotating the handwheel. The working principle and structure of this part are existing technologies, so they will not be described in detail here.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By adding an independent and detachable collection bin to the traditional collection base, waste materials can be collected in a unified manner. When cleaning is required, the operator only needs to remove the entire collection bin from the collection base for cleaning. This not only avoids the risk of flying chips and cross-contamination caused by traditional brush scraping, but also eliminates the need to disassemble the collection base. This improves the shortcomings of the existing device in cleaning. Attached Figure Description
