Description

Technical Field

[0001] The invention belongs to the technical field of tissue embedding and solidification, and in particular relates to an ultra-large bone tissue embedding machine. Background Art

[0002] Photocuring generally refers to the photocuring of unsaturated polyester resin; the activation energy generated by ultraviolet light with the highest energy in the spectrum can break the C-C bond of the unsaturated polyester resin, generate free radicals and solidify the resin. When a photosensitizer is added to the unsaturated polyester resin, ultraviolet light or visible light is used as an energy source to trigger the resin to undergo a cross-linking reaction quickly, and the resin will continuously transform from liquid to solid. Existing photocuring machines are equipped with a fixed platform inside, and a plurality of fixed grooves are provided at the upper end of the fixed platform, and a mold is placed in the fixed groove. Liquid resin is poured into the mold, and then the liquid resin is treated with light by a curing yellow-violet light.

[0003] Specifically, when making slices or ultra-thin slices, it is difficult to directly make slices of uniform thickness because the tissue is soft or the local hardness is inconsistent. Therefore, it is necessary to use a certain substance to penetrate the inside of the tissue and use different polymerization methods to make the entire tissue harden in the same way, so as to facilitate cutting into thin slices. However, the current method adopted at home and abroad is to first cut the large tissue and then embed the cut tissue. During the light curing process, it is necessary to continuously fill the water tank with water to cool the embedding mold. The existing design only uses a circulating pump to pump water. The water temperature cannot be constant during the circulation process. At the same time, the flow path of the cooling water is not optimized. It is only discharged directly between the water inlet and the outlet. It is impossible to completely contain the embedding mold for sufficient cooling treatment, which leads to insufficient cooling of the inside of the embedding mold, affecting the overall effect of curing embedding.

[0004] In view of this, the present invention is proposed. Summary of the invention

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0039] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figures 1 to 9As shown, an ultra-large bone tissue embedding machine described in the present invention includes a water tank 7, an embedding mold is set up in the water tank 7, and the rear side of the water tank 7 is provided with a water inlet and a drain for filling and discharging cooling water into and out of the water tank 7. The embedding machine also includes a support plate 3, and two door bodies 2 are hinged on both sides of the support plate 3. The door body 2 has a surrounding edge, and when the plate surfaces of the two door bodies 2 are rotated to be parallel to each other, the embedding mold can be surrounded and closed.

[0042] Among them, a lamp group 6 consisting of a yellow light tube and a blue light tube is respectively arranged on the door body 2, and a base 1 is arranged on the front side of the embedding machine, and the rear side of the base 1 is connected to the support plate 3. Among them, there is a convex edge at the central position of the support plate 3, and the convex edge is fixedly connected to a vertically arranged fixed shaft 5 by bolts, and a lamp tube bracket 4 is slidably connected to the fixed shaft 5, and the lamp tube bracket 4 is also provided with a yellow light tube and a blue light tube, and each lamp tube is directly above the embedding mold. The lamp tube bracket 4 is locked by a lock buckle, so that the lock buckle can be flexibly adjusted when taking and placing the embedding mold and adjusting the height position of each lamp tube relative to the embedding mold. The overall curing embedding process is controlled by a controller 14.

[0043] Specific curing working principle: After the controller 14 is started, the duration of yellow-blue light irradiation is set on the interface of the controller 14, and the lamp group 6 to be started is selected;

[0044] Place the fresh tissue that has been processed in the previous stage into the corresponding embedding mold, pour in the photosensitive resin (the liquid level can be 1 mm or more above the height of the tissue sample), and place the entire mold on the water tank 7, cover it with a cover plate, and lock the buckle;

[0045] Adjust the lamp group 6 on the lamp holder 4 and the embedding mold to a suitable distance through the lock;

[0046] After the setting is completed, click the start button on the display interface of the controller 14, the yellow light tube starts, and after the yellow light setting time is reached, the yellow light tube goes out, and it automatically jumps to the blue light tube to start. After the blue light setting time is reached, the blue light tube goes out, and the entire light cycle ends. It should be noted that the light-cured embedding first uses low-intensity light and maintains the temperature below certain conditions to fully cure the embedding material. Then, the embedding material that has penetrated into the tissue is completely cured by using high-intensity blue light.

[0047] The photosensitive resin Technovit7200VLC is a product specially developed to improve thin-section grinding technology. It can completely penetrate hard tissues, has high mechanical strength, and can significantly improve thin-section grinding technology. With this technology, it is no longer necessary to decalcify the tissue.

[0048] When performing light-curing embedding operations, a large amount of heat is generated during the entire illumination process. To prevent the interior of the tissue sample from being damaged during the curing process, it is necessary to reduce the heat generated by the photosensitive resin during the polymerization process. The existing practice is to use an external water cooling system. However, in order to prevent the cooling water from overflowing, the water injection is only stopped when the water is filled to a height that contacts the bottom of the embedding mold. The embedding mold is cooled by the cooling water at the bottom. On the one hand, the surrounding wall of the entire embedding mold cannot be cooled. On the other hand, the overall water injection action is not performed continuously, so the heat dissipation efficiency is low and the effect is limited.

[0049] In order to overcome the above-mentioned defects, the present invention has also made the following improvements:

[0050] It also includes a plurality of partition plates 92, with a sleeve opening in the middle adapted to the embedding mold, and the plurality of partition plates 92 are sequentially sealed and sleeved along the height direction of the embedding mold, and the outer peripheral wall of the partition plate 92 fits with the inner wall of the water tank 7 to form a plurality of water-filled chambers, and the front side or the rear side of each partition plate 92 is alternately provided with through holes 921, so that each water-filled chamber is connected to form a water passage for cooling the embedding mold;

[0051] The cooling water tank 8 is externally connected to the water inlet and the drain outlet of the water tank 7 to form a circulating water circuit for continuously filling and draining the water tank 7 .

[0052] In the present invention, a plurality of partition plates 92 are arranged at intervals along the vertical direction on the inner wall of the water tank 7, wherein a sleeve is arranged on the central side wall of the partition plate 92, and a rubber layer is arranged on the side wall of the sleeve. The opening of the embedding mold has a flange, so that after the entire embedding mold is placed in the water tank, it can be erected therein by the flange. Then a cover plate is arranged on the top and locked by a snap. Through the partition plate 92 arranged between the embedding mold and the water tank 7, a plurality of water-filled chambers can be formed between the two. A through hole 921 is arranged on one side of the partition plate 92, and a through hole 921 is also arranged on the other side (i.e., the front and rear positions) of the adjacent partition plate 92. Through the through holes 921 arranged alternately in the front and rear, the various water-filled chambers can be connected to form a water passage. In addition, the water inlet in the water tank 7 is located above the drain port, so that during the process of filling cooling water, the cooling water can gradually flow from the top water-filled chamber to the lower water-filled chamber until it is discharged from the drain port, so that the overall cooling water flow path is longer, and the surrounding wall and bottom of the embedded mold can be fully cooled at the same time, so that the cooling efficiency and effect are significantly improved. In addition, a rubber layer is provided on the sleeve in the center of each partition plate 92, which can ensure the sealing between each water-filled chamber and the water flow path on the one hand; on the other hand, it increases the friction between the partition plate 92 and the embedded mold, preventing the embedded mold from having a tendency to "float" after being filled with cooling water, and effectively preventing cooling water from overflowing.

[0053] Furthermore, by adding a cooling water tank 8, cooling water is stored in the cooling water tank 8, and a circulating water path is formed with the entire water tank 7, so that the embedded mold in the water tank 7 can be continuously and sufficiently cooled, thereby improving the cooling efficiency.

[0054] Furthermore, each partition plate 92 is symmetrically provided with a U-shaped plate 91, and the upper and lower sides of the U-shaped plate 91 are respectively sealed and slidably provided with the side walls of the adjacent partition plates 92;

[0055] An elastic member is disposed on one side of the U-shaped plate 91 away from the embedding mold, and the free end of the elastic member is disposed against the inner wall of the water tank to adapt to the impact of cooling water on the U-shaped plate 91 and / or the embedding mold.

[0056] In the present invention, U-shaped plates 91 are symmetrically arranged between each partition plate 92, and the openings of the opposite U-shaped plates 91 are arranged opposite to each other. The U-shaped plates 91 can freely slide horizontally between adjacent partition plates 92, wherein there is a gap between the side wall of the opening end of the U-shaped plate 91 and the inner wall of the water tank 7, and an elastic member is arranged in this gap, so that the direction of the water flow cannot be controlled during the process of filling the cooling water. By using the setting of the U-shaped plates 91 that can slide freely on both sides and have an elastic reset function, the water pressure can be adaptively adjusted to adjust the gap between the U-shaped plate 91 and the embedding mold, thereby effectively preventing the cooling water from overflowing due to the water pressure shock.

[0057] Specifically, the elastic member includes an extrusion rod 93 and an extrusion spring 94 . The extrusion rod 93 is a telescopic rod, and an extrusion spring 94 is sleeved on the outside of the extrusion rod, and both ends of the extrusion rod are respectively against the U-shaped plate 91 and the inner wall of the water tank 7 .

[0058] Furthermore, a liquid level port is provided at the rear side of the water tank, and the liquid level port is connected to a vertically arranged branch pipe 12 , and a liquid level meter 11 which can be sealed and slid up and down is provided in the branch pipe 12 for detecting the liquid level of the cooling water inside the water tank 7 .

[0059] In the present invention, two liquid level ports are symmetrically arranged on the rear side of the water tank, wherein the liquid level ports are connected through a branch pipe 12, and a liquid level gauge 11 is slidably arranged on the vertical pipe of the branch pipe 12, wherein the outside of the liquid level gauge 11 is in sealing contact with the inner wall of the branch pipe 12. The water level height to be filled is selected according to the material inside the embedding mold, and during the cooling water flow, the water level in the water tank 7 is continuously detected by the liquid level gauge 11 to prevent the water flow from being too large or too small to affect the cooling water level, thereby affecting the heat dissipation effect set during the entire embedding curing process.

[0060] Specifically, the liquid level gauge 11 is adjusted in height by the driving mechanism 10. The driving mechanism 10 includes a driving motor 101, a screw 102, a threaded sleeve 103, and a limiting rod 104 and a limiting sleeve 105 for limiting functions, wherein the driving motor 101 is electrically connected to the controller 14. According to the heat dissipation requirements of the embedding mold, it is necessary to limit the cooling water level filled in the water tank 7, and then the liquid level gauge 11 is adjusted to a set height by the driving motor 101.

[0061] Furthermore, a cooling water tank inlet pipe 81 is provided at the water inlet of the cooling water tank 8, and the cooling water tank inlet pipe 81 is provided with at least a telescopic hose 83 between the water inlet of the cooling water tank 8 and the water outlet of the water tank 7, and a support rod 106 is provided on one side of the liquid level meter 11, and the support rod 106 is connected to the outer wall of the telescopic hose 83.

[0062] In the present invention, a cooling water tank inlet pipe 81 is connected to the water inlet of the cooling water tank 8, wherein the water inlet pipe has a telescopic section, that is, a telescopic hose 83 is provided at the end of the cooling water tank inlet pipe 81, and a support rod 106 is provided on the outside of the liquid level meter 11, and a hanging hole is provided at the bottom of the support rod 106, and the telescopic hose 83 is passed through the hanging hole and connected to the cooling water tank 8 and the water tank 7 respectively. The telescopic hose 83 is lifted to a pointed state through the hanging hole of the support rod 106. Since the water level inside the water tank is detected by the liquid level meter 11, and the detection corresponding to different water level heights is performed by adjusting the height of the relative liquid level port of the liquid level meter 11, in the process of moving the liquid level meter 11, the support rod 106 will drive the telescopic hose 83 to protrude upward to form pointed heads of different heights. At this time, the highest position of the telescopic hose 83 is consistent with the water level height of the internal water tank. On the one hand, the water level inside the water tank can be judged by observing the height of the pointed head of the telescopic hose 83, and on the other hand, a certain liquid level difference is formed, so that the appropriate water pressure can be adjusted when the water tank 7 is drained. That is, the height of the telescopic hose 83 is correlated with the set water level height and water pressure, ensuring that the overall circulation of cooling water is more controllable.

[0063] Furthermore, the partition plate 92 has a hollow cavity inside, and an air outlet and an air inlet are respectively arranged on the rear side thereof. Each air inlet is connected to an air inlet pipe 95 and is connected through a three-way pipe. The bottom air inlet pipe 95 is connected to an induced draft fan; each air inlet pipe 95 is connected to an air outlet pipe 96.

[0064] In the present invention, each partition plate 92 has a hollow cavity inside, wherein at the through hole 921 located on the partition plate 92, there is a channel inside to separate it from the hollow cavity, that is, the hollow cavity is not connected to the through hole 921. The left and right sides of each partition plate 92 are respectively provided with an air inlet and an air outlet, and each air inlet and air outlet is led out through an air inlet pipe 95 and an air outlet pipe 96, and is connected between two adjacent air inlet pipes 95 and two adjacent air outlet pipes 96 through a three-way pipe, and is led out or introduced through a total air inlet pipe 95 and air outlet pipe 96. Specifically, an induced draft fan is provided at the pipe mouth of the air inlet pipe 95, so that cold air can be introduced into each partition plate 92 through the induced draft fan, so that the embedded mold can be further cooled and heat-dissipated.

[0065] Furthermore, a reset control valve 97 is provided at the air inlet of each air inlet pipe 95 and the corresponding partition plate 92, and an extrusion portion 107 is provided on one side of the support rod 106, extending from the side wall of the support rod 106 close to the reset control valve 97, and the extension length is not greater than the reset stroke of the reset control valve 97.

[0066] In the present invention, a reset control valve 97 is provided between the three-way pipe at the bottom or the air inlet pipe 95 at the bottom and the air inlet of the partition plate 92. When the support rod 106 is driven upward by the liquid level meter 11, the reset end of the reset control valve 97 can be squeezed in sequence by the action of the extrusion part 107, so that the reset control valve 97 is turned on, and then the air path of the partition plate 92 of the corresponding height can be turned on, so that the opening of the reset control valve 97 at different heights can be determined according to the actual heat dissipation requirements of the embedded mold, thereby more intelligently controlling the air outlet mode of the air cooling, and the overall air cooling is more controllable.

[0067] Furthermore, a sliding plate that can slide horizontally is provided inside the cooling water tank 8 to divide the cooling water tank 8 into two left and right chambers, namely a heat dissipation chamber and a water storage chamber. An electromagnetic one-way valve for connecting the two chambers is provided on the sliding plate. A water pump 84 is provided in the water storage chamber. The water pump 84 is connected to a cooling water tank outlet pipe 82, which is connected to the water inlet of the water tank 7, for filling the cooling water into the water tank 7.

[0068] In the present invention, a vertically arranged sliding plate is arranged in the cooling water tank 8, wherein the sliding plate divides the cooling water tank 8 into a heat dissipation chamber and a water storage chamber on the left and right sides, wherein an electromagnetic one-way valve capable of controlling whether the two chambers are connected is arranged on the sliding plate. By using a water pump 84 arranged on the water storage chamber, the cooling water in the water storage chamber can be pumped into the water tank 7 through the cooling water tank outlet pipe 82. After part of the cooling water is pumped in, the pressure in the water storage chamber is reduced to form a negative pressure, and the corresponding heat dissipation chamber will be fed with cooling water that takes out the heat in the embedded mold through the cooling water tank inlet pipe 81, and the cooling water in the heat dissipation chamber is cooled to cool the water temperature. That is, the cooling water with heat will not be directly circulated and mixed with the cooling water in the water storage chamber, thereby ensuring that the water temperature of the cooling water filled in the water tank 7 is always constant and meets the heat dissipation standard.

[0069] Furthermore, a temperature sensor is provided in the heat dissipation cavity for detecting the temperature of the cooling water filled into the heat dissipation cavity. The temperature sensor is electrically connected to the electromagnetic one-way valve and is controlled by an external controller 14 .

[0070] In the present invention, a temperature sensor is arranged in the heat dissipation chamber to continuously detect the water temperature of the cooling water filled therein. When the water temperature detected by the temperature sensor meets the temperature of the heat dissipation standard or is consistent with the water temperature of the water storage chamber, the electromagnetic one-way valve can be opened by the controller 14 to fill the water in the heat dissipation chamber into the water storage chamber, thereby ensuring that the water pump 84 can continuously extract cooling water of constant temperature that meets the heat dissipation standard from the water storage chamber.

[0071] Furthermore, a plurality of heat dissipation fins 1306 are provided outside the cooling water tank 8 and are arranged at intervals along the horizontal side wall of the cooling water tank 8;

[0072] A sliding rod 1302 is connected to one side of the sliding plate. The sliding rod 1302 penetrates the side wall of the cooling water tank 8 and is connected to a retractable heat dissipation film 1305 . The heat dissipation film 1305 at least covers the top of the heat dissipation cavity and contacts the heat dissipation fins 1306 .

[0073] In the present invention, a plurality of heat dissipation fins 1306 are arranged outside the cooling water tank 8 to assist the cooling water in the heat dissipation cavity of the cooling water tank 8 to exchange heat with the outside. A sliding plate is provided with a transversely arranged sliding rod 1302 on one side of the water storage cavity, and the sliding rod 1302 penetrates the side wall of the cooling water tank 8 and is sealed and slidable. Specifically, a linkage assembly 13 is arranged on the outside of the cooling water tank 8, wherein the linkage assembly 13 includes a mounting frame 1301 arranged on the outside of the cooling water tank 8, and a guide hole is also arranged on the mounting frame 1301, and the free end of the sliding rod 1302 passes through the guide hole and is connected to an L-shaped rod 1304, and the free end of the L-shaped rod 1304 is connected to a retractable heat dissipation film 1305, and the coverage of the heat dissipation film 1305 is the same as the top length of the heat dissipation cavity.
