Description
Technical Field
[0001] This utility model relates to the field of wax block trimming technology, specifically to a multifunctional high-throughput wax block trimming instrument. Background Technology
[0002] Paraffin embedding is a key technique in pathology and biology for preparing tissue sections. The main steps involve immersing fixed, dehydrated, and cleared biological tissue in liquid paraffin. After the paraffin has penetrated, it cools and solidifies to form a solid paraffin block. This process effectively preserves the integrity of the tissue structure, facilitating the subsequent cutting of ultrathin sections (typically 2-5 micrometers) using a microtome. These sections are then stained for microscopic pathological diagnosis or scientific observation. Paraffin embedding offers advantages such as long preservation time and stable section quality, making it a routine pretreatment method for clinical pathological diagnosis and medical research.
[0003] In routine embedding procedures in pathology departments, after embedding using paraffin blocks, residual wax often remains on both sides of the blocks, preventing direct attachment to the microtome. This residual wax needs to be removed. In facilities without a paraffin block trimming device, technicians must manually trim individual blocks using a small scalpel, a method that is inefficient and carries a risk of cuts. Common paraffin block trimming devices typically have only one heating surface, requiring technicians to operate with one hand, trimming a small number of blocks at a time. After trimming one side, the block is flipped to trim the other side. While more efficient than the scalpel method, this requires holding the block continuously, interfering with other tasks, and the trimming process is tedious. Therefore, a technical solution is urgently needed to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a multifunctional high-throughput wax block trimming instrument to solve the problems in the prior art.
[0005] To solve the above-mentioned technical problems, this utility model specifically provides the following technical solution: a multifunctional high-throughput wax block trimming instrument, including an electrical control box base, a heating box fixedly installed on the top of the electrical control box base, a first heating plate fixedly installed on the bottom of the heating box, a receiving box placed on the first heating plate, a plurality of limiting clamps slidably installed inside the receiving box, wherein a wax block box is placed between every two of the limiting clamps, a box cover is rotatably connected to the top of the heating box, a second heating plate is fixedly connected to the bottom of the box cover, the first heating plate and the second heating plate are both electrically connected to the electrical control box base, an outlet groove for discharging wax liquid is opened at the bottom of the receiving box, and a collection box is fixedly installed on the side wall of the electrical control box base, and the top of the collection box is flush with the bottom of the outlet groove.
[0006] Based on a preferred embodiment of a multifunctional high-throughput wax block trimming instrument, both the electrical control box base and the heating box are inclined.
[0007] Based on a preferred solution provided by a multifunctional high-throughput wax block trimming instrument, multiple partitions are fixedly installed inside the container, and the multiple partitions divide the container into multiple storage compartments. Each storage compartment is fixedly installed with two guide rods, and the two ends of the limiting clamp are slidably connected to the two guide rods respectively.
[0008] Based on a preferred solution provided by a multifunctional high-throughput wax block trimmer, the bottom of all the guide rods is slidably connected to the same first slide plate, the top of all the guide rods is slidably connected to the same second slide plate, and the bottom of each guide rod is fitted with a spring, with the two ends of the spring respectively abutting against the inner wall of the container and the bottom of the first slide plate.
[0009] Based on a preferred embodiment of a multifunctional high-throughput wax block trimming instrument, the bottom of the container is provided with an inclined groove for collecting wax liquid, and the bottom of all the inclined grooves are connected to the outlet groove.
[0010] Based on a preferred embodiment of a multifunctional high-throughput wax block trimmer, a pressing handle is slidably mounted on the top of the heating box, and the bottom of the pressing handle penetrates the side wall of the container and abuts against the top of the second sliding plate.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] 1. This utility model utilizes a dual-heating-plate design (first and second heating plates) to simultaneously melt residual wax on both sides of the wax block box, eliminating the need for manual flipping. Compared to traditional single-heating-plate equipment, this reduces the time required for a single operation and completely avoids the safety risks associated with handling the wax block box.
[0013] 2. This utility model adopts a compartmentalized container design. Through partitioned storage compartments and spring-loaded clamps, the device can process dozens of wax block boxes at a time. Compared to the traditional one-by-one operation mode, processing efficiency is improved, and continuous operation is achieved through quick replacement of pre-loaded boxes.
[0014] 3. This utility model utilizes a tilted electrical control box base combined with a bottom inclined groove and an outlet groove, employing a fluid dynamic design to automatically guide molten wax to a collection box. This results in a low wax residue rate, reduces the burden of manual cleaning, and ensures a clean operating environment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] Example
[0026] like Figures 1 to 6 As shown, this utility model provides a multifunctional high-throughput wax block trimming instrument, including an electrical control box base 1. A heating box 2 is fixedly installed on the top of the electrical control box base 1, and a first heating plate 3 is fixedly installed on the bottom of the heating box 2. A receiving box 4 is placed on the first heating plate 3. Multiple limiting clamps 5 are slidably installed inside the receiving box 4, and a wax block box 6 is placed between every two limiting clamps 5. A box cover 7 is rotatably connected to the top of the heating box 2, and a second heating plate 8 is fixedly connected to the bottom of the box cover 7. Both the first heating plate 3 and the second heating plate 8 are electrically connected to the electrical control box base 1. An outlet groove 9 for discharging wax liquid is opened at the bottom of the receiving box 4. A collection box 10 is fixedly installed on the side wall of the electrical control box base 1, and the top of the collection box 10 is flush with the bottom of the outlet groove 9.
[0027] As a further explanation of this embodiment, the usage process of this device in this embodiment is as follows: Open the box cover 7, take out the container box 4, and place the wax block boxes 6 that need to be trimmed one by one into the limiting clamp 5. After the wax block boxes 6 are placed, put the container box 4 filled with wax block boxes 6 back into the heating box 2, close the box cover 7, and control the first heating plate 3 and the second heating plate 8 or simultaneously turn on the heating through the electrical control box base 1 (in this embodiment, the electrical control box base 1 is an abbreviation for the integrated power control device in the prior art, i.e., the box that controls the power supply or opening and closing) to control the heating. Due to the different wax block embedding operation process, it may be possible for residual wax to condense on one or both sides of the wax block box 6. In this embodiment, it is set that residual wax adheres to both sides of the wax block box 6. Since the first heating plate 3 and the second heating plate 8 are close to the two sides of the wax block box 6, the two sides of the wax block box 6 absorb heat and heat up rapidly, causing the wax blocks attached to the two sides of the wax block box 6 to melt into liquid, thereby achieving the trimming effect of the wax block box 6. As a preferred embodiment, the device can be equipped with multiple containers 4. While the heating box 2 is being heated and trimmed, the operator can place other wax block boxes 6 that need trimming into the containers 4 one by one to wait for the trimming operation. After the trimming operation of the previous batch of wax block boxes 6 is completed, the containers 4 can be replaced directly to quickly start the trimming operation of the next batch of wax block boxes 6, thereby improving the overall trimming efficiency of the wax block boxes 6.
[0028] As an embodiment of a multifunctional high-throughput wax block trimming instrument, both the electrical control box 1 and the heating box 2 are inclined.
[0029] As a further explanation of this embodiment, since the residual wax melts after absorbing heat and becomes liquid, in order to prevent the wax from flowing freely, the heating box 2 is placed at an angle, so that the wax is pulled down by gravity and flows into the collection box 10 through the outlet groove 9 at the bottom of the receiving box 4, thereby completing the collection of the wax. In this embodiment, the collection box 10 is sprayed with an anti-wax coating, so that the wax does not easily stick to the inside of the collection box 10 after cooling, which facilitates the cleaning and maintenance of the collection box 10. As a further preferred solution of this embodiment, the collection box 10 is detachably connected to the electrical control box base 1. A disposable plastic bag is placed inside the collection box 10. Simply pack the plastic bag containing the wax and replace it with a new plastic bag to ensure the cleanliness of the inside of the collection box 10. Alternatively, the collection box 10 can be removed directly, and the inside of the collection box 10 can be cleaned to maintain the cleanliness of the inside of the collection box 10. In addition, since the heating box 2 is tilted and the container box 4 is placed inside the heating box 2, all the wax block boxes 6 also tilt as the heating box 2 tilts. Therefore, when the residual wax on both sides of the wax block box 6 melts, the resulting liquid wax flows from top to bottom, which facilitates the collection of the liquid wax and prevents the liquid wax from stagnating on the side wall of the wax block box 6, ensuring that the side wall of the wax block box 6 does not become residual wax again after cooling.
[0030] As an embodiment of a multifunctional high-throughput wax block trimming instrument, multiple partitions 11 are fixedly installed inside the container 4, which divide the container 4 into multiple storage compartments 12. Each storage compartment 12 is fixedly installed with two guide rods 13, and the two ends of the limiting clamp 5 are slidably connected to the two guide rods 13 respectively.
[0031] As a further explanation of this embodiment, in this embodiment, multiple storage compartments 12 are formed by the partition 11, and the width of the storage compartment 12 is similar to the width of the wax block box 6, so that the container box 4 can hold more wax block boxes 6 at one time, thereby improving the overall edge trimming efficiency of the wax block boxes 6. In addition, the limiting clamp 5 in this application is completely attached to the side wall of the wax block box 6. The limiting clamp 5 separates the wax block boxes 6, avoiding direct contact between the wax block boxes 6 to form gaps, so that the melted wax flows into the wax block box 6 along the gaps.
[0032] As an embodiment of a multifunctional high-throughput wax block trimming instrument, the bottom of all guide rods 13 is slidably connected to the same first slide plate 14, the top of all guide rods 13 is slidably connected to the same second slide plate 15, and the bottom of each guide rod 13 is fitted with a spring 16, with the two ends of the spring 16 respectively abutting against the inner wall of the container 4 and the bottom of the first slide plate 14.
[0033] As a further explanation of this embodiment, in this embodiment, the elastic force provided by the spring 16 presses the limiting clamp 5 against the wax block box 6 to avoid gaps between the wax block box 6 and the limiting clamp 5. In addition, the two adjacent limiting clamps 5 in this application are provided with mutually cooperating barriers on both sides, which not only restricts the possibility of the wax block box 6 moving left and right, but also ensures that the two limiting clamps 5 will not be completely fitted when no wax block box 6 is placed between them, leaving a certain space so that the operator can move the two limiting clamps 5 when handling the wax block box 6.
[0034] As an embodiment of a multifunctional high-throughput wax block trimmer, the bottom of the container 4 is provided with a sloping groove 17 for collecting wax liquid, and the bottom of all sloping grooves 17 is connected to the outlet groove 9.
[0035] As an embodiment of a multi-functional high-throughput wax block trimmer, a pressing handle 18 is slidably mounted on the top of the heating box 2, and the bottom of the pressing handle 18 penetrates the side wall of the housing 4 and abuts against the top of the second sliding plate 15.
[0036] As a further explanation of this embodiment, in order to further improve the efficiency of trimming the wax block box 6, in this application, when the pressing handle 18 is pushed down, the bottom of the pressing handle 18 abuts against the second sliding plate 15, thereby causing all the wax block boxes 6 in the container 4 to slide down, thereby causing the first sliding plate 14 to compress the spring 16 downward. When the pressing handle 18 is pulled up again, the spring 16 returns to its original state and pushes the first sliding plate 14 upward, causing all the wax block boxes 6 to return to their original position. The above operation is repeated, and the pressing handle 18 is pushed and pulled repeatedly, so that all the wax block boxes 6 slide up and down in the container 4, passing through the wax blocks. The friction between box 6 and inclined groove 17 physically eliminates the residual wax adhering to the wax block box 6, reduces the thickness of the residual wax, and makes the residual wax easier to absorb heat and melt. The wax liquid at the top of the wax block box 6 flows downward faster during the up and down sliding process and flows into the inclined groove 17 along the side wall of the limiting clamp 5, further reducing the possibility of wax liquid residue. In addition, in order to further limit the flow direction of the wax liquid, a pad can be placed on one side of the bottom of the receiving box 4 when installing the receiving box 4, so that the receiving box 4 tilts left and right, and the wax liquid at the top of the wax block box 6 flows along the tilt direction, further improving the trimming efficiency of this device. As a further explanation of this embodiment, this device also has more ways of use. A third heating plate is provided on the surface of the lid 7. The third heating plate is electrically connected to the electrical control box base 1, and the surface of the third heating plate is provided with a slanted groove 17. This allows the device to be used without opening the lid 7. The wax block box 6 can be held directly and the side of the wax block box 6 with residual wax can be rubbed against the surface of the third heating plate. With the help of the slanted groove 17 on the surface of the third heating plate, the residual wax on the side wall of the wax block box 6 can be quickly removed. The third heating plate can be used when trimming a small number or individual wax block boxes 6, making the use of this device more flexible and versatile, and saving energy consumption.
