Description

Technical Field

[0001] The utility model relates to the technical field of slicers, in particular to a portable tissue slicer used for cutting animal soft tissues. Background Art

[0002] A tissue slicer is an instrument used to cut human diseased tissue or other materials into pathological slices or tissue sections. It is widely used in the fields of medicine and biology. It is mainly used for the general morphological structure detection of various tissues or cell components and lesions, providing strong support for pathological diagnosis and scientific research.

[0003] At present, the common tissue slicers on the market are divided into rotary slicers, sliding slicers, freezing slicers, vibrating slicers and ultra-thin slicers according to the tissue embedding method or slicing method. Rotary slicers are mainly used to provide paraffin slices; sliding slicers are mainly used for larger tissue slices embedded in collodion; freezing slicers are mainly used for slicing frozen tissues; vibrating slicers cut tissues by vibration and are suitable for certain specific types of tissue slices; ultra-thin slicers are mainly used to prepare extremely thin tissue slices to meet the needs of specific research. However, the above tissue slicers almost all require the tissue to be frozen or embedded before cutting, which will cause the cells to lose activity during the freezing or embedding process.

[0004] In the fields of biology, medicine and biotechnology research, it is necessary to observe active animal tissues or culture animal tissues in vitro, so as to intuitively understand the structure, function and interaction of cells, tissues and organs. However, since the above-mentioned tissue slicers need to freeze or embed the tissues before cutting, which will cause the cells to lose their activity, they cannot meet the needs of retaining tissue activity after tissue slicing and culturing tissue slices in vitro. In addition, most of the existing tissue slicers cut tissue blocks vertically, and the vertical cutting method is not convenient for fixing active animal soft tissues during cutting.

[0005] The purpose of the utility model is to provide a portable tissue slicer for animal soft tissue cutting, which has a simple structure and is easy to operate. It can achieve the limiting and rapid cutting of animal soft tissue blocks in the tissue slicer, so that the cut animal soft tissue slices remain active. The device is easy to assemble and disassemble, is lightweight and portable, and has strong practicality.

[0006] The technical solution adopted to achieve the purpose of this utility model is:

[0007] A portable tissue slicer for animal soft tissue cutting comprises, from bottom to top, a base, a dividing plate and a cover plate, wherein the dividing plate is movably connected to the base, and the cover plate is detachably connected to the dividing plate; the middle part of the bottom surface of the cover plate is suspended, and a cutting gap is formed between the suspended middle area and the dividing plate for a cutting tool to pass through; a placing boss is provided on the base below the cutting gap, an upper placing through hole matching the placing boss is opened on the dividing plate, and the placing boss extends into the placing through hole.

[0013] Furthermore, a positioning hole is provided at the bottom of the cover plate, a pin hole corresponding to the positioning hole is provided on the upper surface of the partition plate, and a positioning pin is provided in the pin hole.

[0014] Furthermore, a limiting circular groove matching the placement through hole is provided at the bottom of the cover plate, and the diameter of the limiting circular groove is greater than or equal to the diameter of the placement through hole.

[0015] Furthermore, the bottom of the cover plate includes contact portions at both ends and a suspended portion in the middle, and the suspended portion includes a limiting portion and tool positioning portions located on both sides of the limiting portion;

[0016] The contact portion is in close contact with the upper surface of the partition plate, the suspended portion is suspended and forms a cutting gap with the partition plate, and the limiting portion is located directly above the placement boss and the placement through hole;

[0017] The heights of the bottom planes of the contact portion, the limiting portion and the tool positioning portion increase in sequence in the vertical direction.

[0018] The device of the utility model is mainly suitable for cutting small animal active soft tissue.

[0034] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 7 As shown, a portable tissue slicer for animal soft tissue cutting comprises, from bottom to top, a base 1, a dividing plate 2 and a cover plate 3, the dividing plate 2 is movably connected to the base 1, and the cover plate 3 is detachably connected to the dividing plate 2; the middle part of the bottom surface of the cover plate 3 is suspended, and a cutting gap 4 for a cutting tool 24 to pass through is formed between the middle suspended area and the dividing plate 2; a placing boss 5 is provided on the base 1 below the cutting gap 4, and an upper placing through hole 6 matching the placing boss 5 is opened on the dividing plate 2, and the placing boss 5 extends into the placing through hole 6.

[0036] In the utility model, the base 1 mainly plays a bearing role, and its shape can be designed according to needs. The shape of the base 1 of the utility model is preferably a rectangular parallelepiped. The rectangular parallelepiped base 1 is relatively wide and has a large bottom support area, so it can be stably placed on the table. The edges and corners of the rectangular parallelepiped base 1 are all rounded, that is, chamfers are opened at each edge of the base 1 and the edges are processed into rounded corners. The corresponding parts of the base 1 are rounded to significantly improve safety, durability and aesthetics. Specifically, the rounding treatment can remove the sharp edges and corners on the base 1 and reduce the risk of injury to the staff; sharp edges and corners are prone to damage or wear of the base 1. The possibility of wear and damage can be reduced through rounding treatment, and the service life of the base 1 can be extended; after the rounding treatment, the sharp edges and corners of the base 1 become smooth, soft and rounded, making the appearance of the base 1 more beautiful and generous. The edges and corners of the dividing plate 2 are rounded, and the edges and corners of the cover plate 3 are rounded.

[0037] In the present invention, hand support parts 20 are left on both sides of the base 1. The hand support parts 20 are grooves or handles, which are convenient for the staff to use their hands to support during transportation. In order to reduce the overall weight of the device, the hand support parts 20 are preferably grooves. During transportation, the staff can lift the base 1 from below with their hands and put their fingers in the grooves to prevent accidental drops caused by hand sliding or device shaking. The groove is square in shape, and the depth of the groove can be designed according to actual needs. The present invention preferably has a depth of 5-10 mm. By designing the groove, the operator can save more effort during transportation and reduce hand fatigue.

[0038] The placement boss 5 provided on the base 1 is mainly used for placing the active animal soft tissue block to be cut. The dividing plate 2 is mainly used for limiting and fixing the active animal soft tissue block to be cut, and controlling the exposure of the active animal soft tissue block to be cut on the dividing plate 2, so as to facilitate subsequent cutting. The dividing plate 2 is movably connected to the base 1. In actual use, the dividing plate 2 can be fixed after moving up and down relative to the base 1, so as to control the height of the placement boss 5 extending into the placement through hole 6, and then after cutting a tissue piece, the active animal soft tissue block to be cut is exposed above the placement through hole 6 for subsequent cutting. The process in which the dividing plate 2 can move up and down relative to the base 1 can be manually pulled above the base 1 to move up and down, and then the dividing plate 2 is locked on the base 1 with the corresponding locking assembly 8. The placement boss 5 in the utility model is a truncated cone or a prism table, and can also be other shapes. The shape of the placement through hole 6 matches the shape of the placement boss 5. For ease of processing, the utility model preferably places The shape of the boss 5 is a truncated cone, and the top of the truncated cone is flush, and the edge is not chamfered. If the edge of the placement boss 5 is chamfered, the edge of the active animal soft tissue block may collapse, affecting the cutting effect. Therefore, the edge of the utility model is not chamfered.

[0039] A cutting slit 4 is formed between the suspended area in the middle of the bottom surface of the cover plate 3 and the dividing plate 2 for the cutting tool 24 to pass through, so as to facilitate cutting. In actual operation, the active animal soft tissue block to be cut is placed and then covered with the cover plate 3. Then the cutting tool 24 passes through the cutting slit 4 from one end of the cutting slit 4, and then the cutting tool 24 is pushed to move in the direction of the active animal soft tissue block to be cut until the cutting tool 24 cuts off the exposed part of the active animal soft tissue block on the dividing plate 2.

[0040] like Figures 1 to 5As shown, a buffer spring 7 is also provided between the base 1 and the dividing plate 2. The dividing plate 2 in the utility model is movably connected to the base 1, and the dividing plate 2 can be fixed after being moved up and down relative to the base 1. A buffer spring 7 is also provided between the base 1 and the dividing plate 2 to play a supporting role. The buffer spring 7 is a spiral spring. The number of buffer springs 7 is more than two, ensuring that at least one is provided at both ends of the base 1, so as to maintain the force balance of the base 1. In the utility model, the two ends of the buffer spring 7 can be fixed on the base 1 and the dividing plate 2 respectively, and a circular interface 21 for inserting the buffer spring 7 is provided on the base 1 and the dividing plate 2. Multiple circular interfaces 21 can be provided, and the specific position is designed according to actual needs. Multiple circular interfaces 21 include large diameter interfaces and small diameter interfaces, so as to facilitate the installation of buffer springs 7 of different diameters. Specifically, since the components such as the dividing plate 2 and the cover plate 3 need to bear weight, relevant circular interfaces 21 are provided, and buffer springs 7 of corresponding specifications can be placed when necessary to bear weight. In addition, since the partition plate 2 can be fixed after being moved up and down relative to the base 1, the buffer spring 7 can also play a buffering role during the up and down movement of the partition plate 2, preventing the partition plate 2 from being pressed down too fast and completely ejecting the active animal soft tissue blocks, and preventing the partition plate 2 from directly falling on the base 1 and impacting and colliding with the base 1. Preferably, in the present utility model, it should be ensured that when there is no external force, the elastic force of all buffer springs 7 can support the weight of the device carried by the upper part, that is, a spring with a suitable stiffness coefficient is selected to prevent the spring from being over-compressed and losing its deformation capacity.

[0041] like Figures 1 to 5 As shown, both ends of the base 1 are provided with locking assemblies 8 for cooperating with the partition plate 2; the locking assembly 8 includes a mounting block 801 fixed on the base 1, and a locking bolt 802 movably arranged on the mounting block 801, and the end of the locking bolt 802 abuts against the partition plate 2; both ends of the partition plate 2 are respectively provided with sliding grooves 9 cooperating with the ends of the locking bolt 802.

[0042] The locking assembly 8 is arranged at both ends of the base 1 and fixedly connected to the sides at both ends of the base 1, and its function is to lock the dividing plate 2 on the base 1. The mounting block 801 is a plate-like structure, and its lower part is fixedly connected to the base 1 by bolts, and the upper part is provided with a bolt hole that penetrates the mounting block 801, and the locking bolt 802 cooperates with the bolt hole. After cutting a piece on the active animal soft tissue block, take out the cut piece. If cutting is still needed at this time, the locking bolt 802 can be loosened, and then the dividing plate 2 is pressed down to the active animal soft tissue block to expose the placement through hole 6, and then the locking bolt 802 is tightened to achieve the fixing of the position of the dividing plate 2, and finally the cover plate 3 is covered to cut. If it is found that the thickness of the surface of the dividing plate 2 exposed by the active animal soft tissue block is too thick during the adjustment process, the locking bolt 802 can be loosened, and then the dividing plate 2 is lifted up to the active animal soft tissue block to expose the appropriate thickness, and then the locking bolt 802 is tightened to achieve the fixing of the position of the dividing plate 2, and finally the cover plate 3 is covered to cut.

[0043] On the one hand, the slide groove 9 provided on the dividing plate 2 can play a limiting role, limiting the end of the locking bolt 802 in the slide groove 9, preventing the end of the locking bolt 802 from tilting when it hits the dividing plate 2; on the other hand, it can also play a guiding role. During the up and down movement of the dividing plate 2, the locking bolt 802 has not completely withdrawn from the slide groove 9. The dividing plate 2 provided with the slide groove 9 can move in the vertical direction along the position of the end of the locking bolt 802, preventing the dividing plate 2 from swinging left and right, thereby improving the stability of the device.

[0044] like Figures 3 to 5 As shown, in the present invention, the bottom of both ends of the dividing plate 2 is also provided with a limit block 22 that matches the end of the locking bolt 802. The purpose of providing the limit block 22 is to prevent the dividing plate 2 from moving too far during the upward movement and pulling the placement boss 5 out of the placement through hole 6. In the present invention, a fixing groove 23 for fixing the limit block 22 is provided at the bottom of the dividing plate 2. After the limit block 22 is inserted into the fixing groove 23, it is connected to the dividing plate 2 by bolts. Figure 6 As shown. An L-shaped notch is provided at one end of the limit block 22 close to the locking assembly 8, so that the bottom of the limit block 22 protrudes, and the horizontal plane of the bottom protruding part of the L-shaped notch is located directly below the slide groove 9, and the width of the horizontal plane of the bottom protruding part of the L-shaped notch is greater than the depth of the slide groove 9, thereby ensuring that the limit block 22 plays a limiting role without affecting the normal operation of the partition plate 2. In the utility model, after the limit block 22 is embedded in the fixing groove 23, the bottom of the limit block 22 is flush with the bottom of the partition plate 2, and the side of the bottom protruding part of the L-shaped notch close to the locking assembly 8 is flush with the side of the partition plate 2. With this structure, the limit block 22 can be completely embedded in the partition plate 2, and the appearance is beautiful and generous.

[0045] In one embodiment of the utility model, in order to prevent the locking bolt 802 from being screwed out of the horizontal part of the L-shaped notch of the limit block 22 when being loosened, a marking line is provided on the locking bolt 802, and the distance from the marking line to the locking head is less than the length of the locking screw exposed above the limit block 22 after the locking screw is tightened. Specifically, the locking bolt 802 includes a locking screw and a locking head, one end of the locking screw is fixedly connected to the locking head, and the other end is suspended after passing through the mounting block 801 and cooperates with the limit block 22. A marking line is provided at one end of the locking screw close to the locking screw, and the distance from the marking line to the locking head is less than the length of the locking screw exposed above the limit block 22 after the locking screw is tightened. In actual use, when tightening the locking bolt 802, the marking line is hidden in the limit block 22. When loosening the locking bolt 802, the locking screw retreats so that the length of the locking screw exposed above the limit block 22 becomes shorter and shorter. If it is loosened too much, the end of the locking screw close to the limit block 22 may be completely hidden in the limit block 22. The utility model designs a marking limit portion on the locking bolt 802 so that the degree of retreat of the locking screw can be observed when loosening the locking bolt 802. If the scale line close to the end of the locking head can be seen, it means that the locking screw exposed above the limit block 22 is about to be completely hidden in the limit block 22. If it is loosened further, it may not play a limiting role. At this time, the locking bolt 802 has been loosened, and the staff can stop tightening the locking bolt 802 and proceed to the next step.

[0046] In the present invention, the locking screw can also be divided into two sections from the marking line, and the two sections are painted with different colors. When loosening the locking bolt 802, observe the degree of retreat of the locking screw. If you can see that the locking screw near the locking head end reveals another color, it means that the locking screw exposed above the limit block 22 is about to be completely hidden in the limit block 22. Loosening it further may not play a limiting role. At this time, the locking bolt 802 has been loosened, and the staff can stop tightening the locking bolt 802 and proceed to the next step.

[0047] like Figures 1 to 5 As shown, fixing seats 10 are further provided at both ends of the upper surface of the dividing plate 2 , and the cover plate 3 is located between the two fixing seats 10 ; a clamping assembly 11 cooperating with the cover plate 3 is also provided on the fixing seat 10 .

[0048] The fixing seat 10 is fixed to the partition plate 2 by bolts, and is mainly used to fix the clamping assembly 11; the clamping assembly 11 is mainly used to cooperate with the cover plate 3, and the cover plate 3 is detachably connected to the partition plate 2, and the cover plate 3 is clamped to the partition plate 2 by the clamping assembly 11. The fixing seat 10 is also provided with a groove or a protrusion on the side in contact with the cover plate 3, and the cover plate 3 is provided with a protrusion or a groove matching the groove or protrusion on the cover plate 3. The fixing seat 10 and the cover plate 3 adopt the method of matching the groove and the protrusion to play a preliminary clamping role, which is convenient for the rapid positioning of the cover plate 3 during the installation process.

[0049] The clamping assembly 11 includes an adjusting bolt 111 and a pressing block 112 sleeved on the adjusting bolt 111; the adjusting bolt 111 passes through the fixing seat 10, and the dividing plate 2 is provided with a receiving through hole 12 for accommodating the adjusting bolt 111; the pressing block 112 can press both ends of the pressing block 112 on the cover plate 3 by rotating around the adjusting bolt 111. The base 1 is provided with a receiving blind hole 25 for accommodating the adjusting bolt 111. The pressing block 112 is an arched strip structure as a whole, and the opening of the arched pressing block 112 faces downward; the outer periphery of the adjusting bolt 111 located on the upper surface of the fixing seat 10 is also sleeved with an adjusting spring 13, and the adjusting spring 13 is divided into two sections, one section is sleeved on the outer periphery of the adjusting bolt 111 above the arched pressing block 112, and the other section is sleeved on the outer periphery of the adjusting bolt 111 above the arched pressing block 112.

[0050] The pressing block 112 is a strip-shaped structure, and its end can be rotated to be placed on the cover plate 3, thereby pressing the cover plate 3 and clamping it above the dividing plate 2. In actual operation, the length of the pressing block 112 exposed above the fixing seat 10 can be adjusted by rotating the adjusting bolt 111, thereby controlling the compression degree of the adjusting spring 13. Since the end of the arched pressing block 112 is in contact with the fixing seat 10 or the cover plate 3, the adjusting spring 13 located above the pressing block 112 is compressed during the process of rotating the adjusting bolt 111 to move downward, and a downward elastic force is applied to the pressing block 112, thereby increasing the pressure on the cover plate 3 when the pressing block 112 clamps the cover plate 3. The adjusting spring 13 located below the pressing block 112 is hardly compressed, and it can adjust the pressure on the cover plate 3 while supporting the pressing block 112. It is mainly reflected in that: when the pressing block 112 is buckled to the cover plate 3, it is equivalent to directly adding a part of the gravity of the pressing block 112 to the cover plate 3. If the active animal soft tissue block exposed outside the placement hole 6 is too thick, the cover plate 3 will be lifted up to a slightly higher height. When the pressing block 112 is closed tightly, the cover plate 3 will be over-squeezed. At this time, the adjustment spring 13 located under the pressing block 112 has a certain upward support for the pressing block 112, reducing the pressure of the pressing block 112 squeezing the cover plate 3 downward, thereby protecting the cover plate 3 from being damaged.

[0051] Based on the above structure of the present invention, the staff can adjust the compression degree of the adjustment spring 13 located above the pressure block 112 by adjusting the length of the bolt 111 exposed above the fixing seat 10, thereby controlling the pressure applied to the cover plate 3 when the pressure block 112 clamps the cover plate 3.

[0052] like Figure 3 and Figure 4 As shown, a positioning hole 14 is also provided at the bottom of the cover plate 3, a pin hole 15 corresponding to the positioning hole 14 is provided on the upper surface of the partition plate 2, and a positioning pin 16 is provided in the pin hole 15. The positioning pin 16 cooperates with the positioning hole 14 to achieve rapid alignment and positioning when the cover plate 3 is installed, thereby improving work efficiency.

[0053] like Figure 3 , Figure 4 and Figure 7 As shown, a limiting circular groove 17 matching the placement through hole 6 is further provided at the bottom of the cover plate 3 , and the diameter of the limiting circular groove 17 is greater than or equal to the diameter of the placement through hole 6 .

[0054] The limiting circular groove 17 is used to accommodate part of the active animal soft tissue block exposed on the dividing plate 2, clamp the active animal soft tissue block, play a certain limiting role, and ensure the smooth cutting of the active animal soft tissue block.

[0055] like Figure 7 As shown, the bottom of the cover plate 3 includes contact portions 18 located at both ends and a suspended portion 19 located in the middle, and the suspended portion 19 includes a limiting portion 191 and tool positioning portions 192 located at both sides of the limiting portion 191;

[0056] The contact portion 18 is in close contact with the upper surface of the partition plate 2, the suspended portion 19 is suspended and forms a cutting gap 4 with the partition plate 2, and the limiting portion 191 is located directly above the placement boss 5 and the placement through hole 6;

[0057] The heights of the bottom planes of the contact portion 18 , the limiting portion 191 and the tool positioning portion 192 in the vertical direction are successively increased.

[0058] The above-mentioned structure of the utility model can make the gap between the tool positioning part 192 and the dividing plate 2 larger, so that the cutting tool 24 can be quickly inserted into the cutting gap 4; and the gap between the limiting part 191 and the dividing plate 2 is smaller, so that the cutting tool 24 can cut along the horizontal plane when cutting the active animal soft tissue block, reducing the up and down tilt of the cutting tool 24, so that the thickness of the part cut off the active animal soft tissue block is more uniform.

[0059] The utility model divides the bottom of the cover plate 3 into contact parts 18 at both ends and a suspended part 19 in the middle, which can ensure that the cover plate 3 and the dividing plate 2 can be tightly connected while reserving a cutting gap 4 for the cutting tool 24 to move. The limiting circular groove 17 is set in the limiting part 191 to ensure that it can cooperate with the placement boss 5 and the placement through hole 6.

[0060] The tissue slicer of the present invention is only for slices of one thickness specification, and the specific size of the distance from the bottom of the thickness limiting circular groove 17 to the top of the placement through hole 6 can be designed according to actual needs.

[0061] In the device of the utility model, the internal spring and connecting screws are all metal parts. Except for the necessary metal parts inside, other structures are all made of transparent acrylic material for easy observation.

[0062] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the scope of the utility model should be included in the protection scope of the utility model.
