Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of pathological examination, and more particularly to a fully enclosed wax block freezing device and a method for using the same. Background Art
[0002] Pathological examination is a method of testing the nature of a disease by providing clear clinical evidence for pathological diagnosis through biopsy, exfoliation and fine needle aspiration cytology. Histopathological sections are made by clamping human tissues and going through a series of steps such as sampling, fixation, washing, dehydration, transparency, waxing, embedding, slicing, dewaxing, staining, dehydration, transparency, and sealing to produce glass slides that can be used to observe cells under a microscope. Paraffin sections are the most widely used method in conventional histological preparation techniques. Paraffin sections are not only used to observe the morphological structure of normal cell tissues, but are also the main method used by disciplines such as pathology and forensic medicine to study, observe and judge the morphological changes of cell tissues. They have also been widely used in research in many other disciplines.
[0003] The core operation step of tissue pathology preparation is pathological sectioning. The quality of the sectioning directly affects the pathologist's diagnosis of the disease. In addition, the pathological specimens are unique and difficult to obtain, so the sectioning process is particularly critical. Therefore, the quality of the wax block directly determines the quality of the sectioning. The wax block must be completely cooled below minus 20℃ before a 2-3um wrinkle-free and knife-mark-free slice can be cut out.
[0004] Currently, after the wax block is sliced, it is necessary to take out the wax block. However, in actual use, the wax blocks are prone to adhere tightly to each other, which makes it more troublesome to take out the wax block, reducing the work efficiency of the technicians. Summary of the invention
[0005] 1. Technical issues to be solved
[0006] Before slicing, the wax block will be exposed to room temperature for a long time after being taken out of the refrigerator. Therefore, in order to avoid the high temperature of the wax block affecting the quality of slicing, we need to freeze the wax block before cutting a high-quality wax slice. Moreover, the existing wax block freezing device is prone to the phenomenon that the wax blocks are tightly adhered to each other, and it is not possible to store a large number of wax blocks, which makes it more troublesome to take out the wax blocks, increases the workload of technicians, and reduces the work efficiency of technicians.
[0007] 2. Technical solution
[0008] To solve the above problems, the present invention adopts the following technical solutions.
[0009] A fully enclosed wax block freezing device comprises a freezing box body, wherein the freezing box body is provided with a plurality of evenly distributed wax block freezing grooves, wherein the wax block freezing grooves are slidably connected to a wax block storage drawer, wherein the wax block storage drawer is provided with a plurality of evenly distributed wax blocks in the storage grooves, wherein an outward push plate is provided in the storage grooves, wherein a pair of first compression springs are fixedly connected between the outward push plate and the bottom end of the wax block freezing grooves, and a raised dividing block is provided between two adjacent wax blocks, wherein a flapper is installed on the wax block storage drawer, wherein the flapper comprises an active hole bored at the upper end of the wax block storage drawer, wherein the active hole is located at the left side of the storage groove, wherein an insertion rod is inserted in the active hole, wherein the upper end of the insertion rod is fixedly connected to a contact circular plate, wherein a second compression spring is fixedly connected between the contact circular plate and the wax block storage drawer, and the second compression spring is located at the outside of the insertion rod, and the bottom end of the contact circular plate is fixedly connected to a contact spring located at the insertion rod. The beating block on the left side of the rod has a magnetic grinding plate embedded in the beating block, the upper and lower inner walls of the storage groove are both provided with strip-shaped through holes matching the beating block, the convex dividing block is provided with a built-in cavity, the left and right inner walls of the built-in cavity are both provided with a plurality of evenly distributed side through holes, the inner walls of the side through holes are fixedly connected with an elastic closing membrane, the built-in cavity is filled with magnetic fluid, and the contact circular plate is repeatedly pressed to force the beating block to extrude the wax block downward, thereby achieving separation of the wax block, and when the magnetic grinding plate contacts the convex dividing block, the magnetic fluid in the convex dividing block is attracted to promote the flow of the magnetic fluid to the left, thereby causing the elastic closing membrane on the right side to bulge outward, reducing the contact area between the wax block and the convex dividing block, thereby promoting the separation of the convex dividing block from the wax block, and after releasing the contact circular plate, the contact circular plate is reset under the reset action of the second compression spring, so as to facilitate the extrusion of the next wax block.
[0010] Furthermore, the outer end of the elastic closing membrane is fixedly connected to a residual wax layer, and a magnetic powder needle is embedded in the residual wax layer. The magnetic grinding plate includes a connecting piece fixedly connected to the beating block, and the outer end of the connecting piece is fixedly connected to the beating block. The magnetic powder layer is formed by the aggregation of multiple magnetic powder needles. When the elastic closing membrane contacts the magnetic grinding plate, part of the magnetic powder needles can be embedded in the surface of the residual wax layer through mutual friction between the two, and under the attraction of the magnetic powder needles to the magnetic fluid, the elastic closing membrane is maintained in a raised state. Therefore, when the residual wax layer on the surface of the opposite through hole is washed with water, the magnetic powder needle can be repeatedly swung by arranging a repeatedly moving magnet block on the outside. On the one hand, it can promote the separation of the residual wax layer and the elastic closing membrane, and on the other hand, it can also collect the magnetic powder needles remaining in the residual wax layer.
[0011] Furthermore, a base is fixedly connected to the bottom end of the freezing chamber, and the base is made of rubber material. By providing the base, the possibility of vibration of the entire freezing chamber can be reduced when the contact circular plate is pressed, thereby improving the stability of the entire device during operation.
[0012] Furthermore, a hook is fixedly connected to the left end of the freezing box body. By providing the hook, the freezing box body can be conveniently hung up when not in use.
[0013] Furthermore, the rear end of the freezing box is electrically connected to a power plug, and the power plug can be conveniently powered on during use.
[0014] Furthermore, a handle is fixedly connected to the outer end of the wax block storage drawer, and the surface of the handle is engraved with anti-slip grooves. By providing the handle, the wax block storage drawer can be easily pulled out of the wax block freezing tank. By providing the anti-slip grooves, the possibility of the technician's hand slipping when touching the handle can be reduced.
[0015] Furthermore, a pressing groove is fixedly connected to the upper end of the contact circular plate, and the diameter of the pressing groove is 1.5-2.5 cm. By providing the pressing groove, it is convenient for technicians to press the contact circular plate.
[0016] Furthermore, the second compression spring and the first compression spring are made of stainless steel.
[0017] Furthermore, the surfaces of the second compression spring and the first compression spring are coated with anti-rust paint. By using stainless steel to make the second compression spring and the first compression spring, the second compression spring and the first compression spring are not easily corroded during long-term use, thereby increasing the service life of the second compression spring and the first compression spring.
[0018] A method for using a fully enclosed wax block freezing device comprises the following steps:
[0019] S1. By repeatedly pressing the contact circular plate, the beating block is forced to squeeze the wax block downward, thereby separating the wax block;
[0020] S2. When the elastic sealing film contacts the magnetic grinding plate, the mutual friction between the two can make part of the magnetic powder needles embedded in the surface of the residual wax layer, and under the attraction of the magnetic powder needles to the magnetic fluid, the elastic sealing film is maintained in a convex state, which is convenient for cleaning the convex separator block and collecting the residual magnetic powder needles;
[0021] S3. When the magnetic grinding plate contacts the raised separator block, it attracts the magnetic fluid in the raised separator block, promoting the magnetic fluid to flow to the left, thereby causing the elastic sealing membrane on the right to bulge outward, promoting the separation of the raised separator block from the wax block.
[0022] 3. Beneficial effects
[0023] Compared with the prior art, the advantages of the present invention are:
[0024] (1) This solution separates the wax block by repeatedly pressing the contact circular plate to force the beating block to squeeze the wax block downward. When the magnetic grinding plate contacts the raised separator block, it attracts the magnetic fluid in the raised separator block and promotes the magnetic fluid to flow to the left, thereby causing the elastic sealing membrane on the right to bulge outward, promoting the separation of the raised separator block and the wax block. When the elastic sealing membrane contacts the magnetic grinding plate, the mutual friction between the two can make part of the magnetic powder needle embedded in the surface of the residual wax layer, and under the attraction of the magnetic powder needle to the magnetic fluid, the elastic sealing membrane is maintained in a raised state, which is convenient for cleaning the raised separator block and collecting the residual magnetic powder needle.
[0025] (2) A base is fixedly connected to the bottom of the freezer body, and the base is made of rubber material. By setting the base, the possibility of vibration of the entire freezer body can be reduced when the contact circular plate is pressed, thereby improving the stability of the entire equipment during operation.
