Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically a constant temperature preservation box for liver cancer tissue slices. Background Technology
[0002] Liver cancer is a malignant tumor of the digestive system. The primary purpose of biopsy analysis in liver cancer is to determine its pathological nature. Currently, because tumors are often large and involve a wide area, longer sections are needed to comprehensively observe the lesion and include the entire tumor tissue. If the tumor is small and localized, the section length can be shorter. For example, a liver cancer with a diameter of 8 cm may require a longer section, while a small liver cancer may only require a shorter section. Different lengths of sections require different sizes of slides and coverslips. The current procedure for preparing liver cancer tissue sections generally involves medical staff laying the tissue sample flat on a slide, covering it with a coverslip, sealing it, and then placing the entire sample in a preservation box.
[0003] Based on the above, the inventors have discovered the following problems: the current preservation box is not adjustable in size, which makes it unsuitable for liver cancer tissue slices of different sizes. The tissue slices cannot be placed stably, which increases the risk of damage to the tissue slices during preservation and transportation, thereby reducing the practicality of the preservation box.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a constant temperature preservation box for liver cancer tissue slices, in order to achieve a more practical value. Utility Model Content
[0005] The purpose of this invention is to provide a constant temperature preservation box for liver cancer tissue slices to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A constant temperature preservation box for liver cancer tissue slices includes a preservation box body and a size adjustment component. The size adjustment component is located below the preservation box body and is used to adjust the distance between the fixed base and the adjusting base. The preservation box body includes a box body with a circular chamber inside. Several fixed bases are installed on the inner wall of the circular chamber. The size adjustment component includes a base with a mounting hole at the center of the upper end of the base. A hollow cylinder is installed inside the mounting hole. Several moving grooves are formed on the outer wall of the hollow cylinder. Adjusting bases are slidably installed inside each of the moving grooves. Each adjusting base is aligned with one of the fixed bases. A vertical groove is formed at the opposite end of each adjusting base and fixed base. The adjusting bases are inclined near the bottom on the side away from the vertical groove. A circular hole is formed at the bottom of each adjusting base. A lifting platform is provided inside the circular hole. Several wedge blocks are installed on the outside of the lifting platform. The wedge blocks are respectively attached to the inclined side of each adjusting base on the side away from the lifting platform.
[0008] Furthermore, each of the wedge-shaped blocks has a sliding groove inside, and each of the sliding grooves has a sliding strip slidably connected inside. Each of the sliding strips is fixedly connected to the inclined side of the adjustment seat on the side away from the lifting platform.
[0009] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the slide groove and the slide bar, the slide groove is set on the wedge block outside the lifting platform, and the slide bar is installed on the inclined surface of the adjusting seat. When the lifting platform moves up or down, under the sliding connection of the slide bar and the slide groove, as well as the action of the wedge block and the inclined surface of the adjusting seat, the adjusting seat moves smoothly through the moving groove.
[0010] Furthermore, a ball screw is rotatably connected to the bottom of the base, one end of which extends through the lifting platform to the outside, and a screw nut is threaded onto the outside of the ball screw. The outside of the screw nut is connected to the inner wall of the lifting platform, and one end of the ball screw is connected to the upper inside of the hollow cylinder via a bearing. The wedge block has a gap between its side away from the lifting platform and the inner wall of the circular hole.
[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting a ball screw, the working principle of the ball screw is common knowledge. The ball screw surface has threaded grooves and the screw nut contains balls. When the ball screw rotates, the balls roll between the ball screw and the screw nut, pushing the screw nut to move along the axial direction of the ball screw, thereby realizing the linear movement of the lifting platform.
[0012] Furthermore, the ball screw has a worm gear sleeved on the outer side of the end away from the hollow cylinder, and a worm is provided inside the base near the worm gear. The two ends of the worm are respectively connected to the inner wall of the base through bearings, and the worm and the worm gear mesh with each other.
[0013] The beneficial effect of adopting the above further solution is that by using the worm and the worm wheel in combination, when the worm rotates, due to the meshing of the worm and the worm wheel, the rotation of the ball screw is realized. At the same time, the worm and the worm wheel have self-locking properties, thus preventing the reverse rotation of the ball screw.
[0014] Furthermore, one end of the worm penetrates through the base and is provided with an internal hexagonal groove.
[0015] The beneficial effect of adopting the above further solution is that by providing an internal hexagonal groove at one end of the worm, the internal hexagonal groove matches with one end of an internal hexagonal wrench. When the user inserts one end of the internal hexagonal wrench into the interior of the internal hexagonal groove, the worm can be rotated by the internal hexagonal wrench.
[0016] Furthermore, one side of the upper end of the box body is hinged with a box cover. A semiconductor refrigeration sheet is installed at the bottom end of the box cover. A plurality of heat dissipation fins are installed at the upper end of the semiconductor refrigeration sheet. The upper ends of the plurality of heat dissipation fins all penetrate through the box cover and extend to the outside. A heater is installed inside the box body. A temperature sensor is installed on the inner wall of the circular chamber between a pair of fixed seats.
[0017] The beneficial effect of adopting the above further solution is that by using the semiconductor refrigeration sheet, the heater and the temperature sensor in combination, when the semiconductor refrigeration works, it cools the interior of the circular chamber of the box body. When the heater works, it heats the interior of the circular chamber of the box body. At the same time, by setting the temperature sensor to monitor the temperature inside the circular chamber of the box body, a constant temperature environment inside the circular chamber of the box body is maintained.
[0018] Furthermore, the bottom end of the box cover is in contact with the upper end of the box body. The bottom end of the box cover and the upper end of the box body are respectively provided with a first installation groove and a second installation groove. A first magnet ring and a second magnet ring are respectively installed inside the first installation groove and the second installation groove. The first magnet ring and the second magnet ring are magnetically attracted to each other. The first installation groove, the second installation groove, the first magnet ring and the second magnet ring are all in the shape of a "hui" character.
[0019] The beneficial effect of adopting the above further solution is that by using the first magnet ring and the second magnet ring in combination, due to the magnetic attraction between the first magnet ring and the second magnet ring, magnetic adsorption realizes the quick sealing of the box cover and the box body.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This constant temperature preservation box for liver cancer tissue slices, by setting a ball screw, when the ball screw rotates, the balls roll between the ball screw and the screw nut, pushing the screw nut to move along the axial direction of the ball screw, thereby realizing the linear movement of the lifting platform. Through the cooperation of the sliding groove and the sliding bar, the sliding groove is set on the wedge block outside the lifting platform, and the sliding bar is installed on the inclined surface of the adjusting seat. When the lifting platform moves up or down, under the sliding connection of the sliding bar and the sliding groove, and the action of the wedge block and the inclined surface of the adjusting seat, the adjusting seat moves smoothly through the moving groove, thereby causing several adjusting seats to expand outward or contract inward, making the distance between the aligned adjusting seats and the fixed seat smaller or larger, thus facilitating the placement of liver cancer tissue slices of different sizes. Since vertical grooves are opened at the opposite ends of the fixed seat and the adjusting seat, it is convenient to place liver cancer tissue slices formed by the combination of coverslips and slides between a pair of vertical grooves.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0028] Please see Figures 1-5 This utility model provides a technical solution: a constant temperature preservation box for liver cancer tissue sections, including a preservation box body 1 and a size adjustment component 2. The size adjustment component 2 is disposed below the preservation box body 1 and is used to adjust the distance between the fixed seat 15 and the adjusting seat. The preservation box body 1 includes a box body 11, and a circular cavity is formed inside the box body 11. Several fixed seats 15 are installed on the inner wall of the circular cavity. The size adjustment component 2 includes a base 21, and a mounting hole is formed at the center of the upper end of the base 21. A hollow cylinder 22 is installed inside the mounting hole. Several moving grooves 24 are formed on the outer wall of the hollow cylinder 22. Adjusting seats 25 are slidably arranged inside each of the several moving grooves 24. The several adjusting seats 25 are respectively aligned with the several fixed seats 15. A vertical groove is formed at the opposite end of each adjusting seat 25 and the fixed seat 15. The several adjusting seats 25 are located away from the vertical groove. One side is inclined near the bottom. The bottom of the adjusting seat 25 has a circular hole 23. Inside the circular hole 23 is a lifting platform 28. Several wedge blocks 29 are installed on the outside of the lifting platform 28. The wedge blocks 29 on the side away from the lifting platform 28 are respectively attached to the inclined side of the adjusting seat 25. When the lifting platform 28 moves up or down, the adjusting seat 25 moves smoothly through the moving groove 24 under the action of the wedge blocks 29 attached to the inclined surface of the adjusting seat 25. This causes the adjusting seats 25 to expand outward or contract inward, making the distance between the aligned adjusting seats 25 and the fixed seat 15 smaller or larger. This makes it easier to place liver cancer tissue slices of different sizes. Since the fixed seat 15 and the adjusting seat 25 both have vertical grooves on their opposite ends, it is easy to place liver cancer tissue slices formed by the combination of coverslips and slides between a pair of vertical grooves.

The sliding strips 26 are fixedly connected to the inclined side of a plurality of adjusting seats 25 on the side away from the lifting platform 28. A ball screw 27 is rotatably connected to the bottom of the base 21. One end of the ball screw 27 extends through the lifting platform 28 to the outside. A screw nut is threaded onto the outside of the ball screw 27. The ball screw 27 is externally connected to the inner wall of the lifting platform 28. One end of the ball screw 27 is connected to the upper inner end of the hollow cylinder 22 via a bearing. The wedge block 29 has a gap between its side away from the lifting platform 28 and the inner wall of the circular hole 23. A worm gear 211 is sleeved on the outside of the end of the ball screw 27 away from the hollow cylinder 22. A worm 212 is provided inside the base 21 near the worm gear 211. Both ends of the worm 212 are connected to the inner wall of the base 21 via bearings. The worm 212 and the worm gear 211 mesh with each other. One end of the worm gear 212 passes through the base 21 and has an internal hexagonal groove 213. This groove 213 matches one end of an internal hexagonal wrench. When the user inserts the wrench into the groove 213, the worm gear 212 rotates. Because the worm gear 212 meshes with the worm wheel 211, the ball screw 27 rotates. The balls roll between the ball screw 27 and the screw nut, pushing the screw nut along... The ball screw 27 moves axially, thereby realizing the linear movement of the lifting platform 28. Through the cooperation of the slide groove 210 and the slide bar 26, the slide groove 210 is set on the wedge block 29 outside the lifting platform 28, and the slide bar 26 is installed on the inclined surface of the adjusting seat 25. When the lifting platform 28 moves up or down, under the sliding connection of the slide bar 26 and the slide groove 210 and the action of the wedge block 29 and the inclined surface of the adjusting seat 25, the adjusting seat 25 moves smoothly through the moving groove 24.
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0032] Please see Figures 1-5, the present utility model provides a technical solution: One side of the upper end of the box body 11 is hinged with a box cover 12. A semiconductor refrigeration sheet 13 is installed at the bottom end of the box cover 12. A plurality of heat dissipation fins 14 are installed at the upper end of the semiconductor refrigeration sheet 13. The upper ends of the plurality of heat dissipation fins 14 all penetrate through the box cover 12 and extend to the outside. A heater is installed inside the box body 11. A temperature sensor is installed on the inner wall of the circular chamber between a pair of fixed seats 15. The bottom end of the box cover 12 is in contact with the upper end of the box body 11. First installation grooves and second installation grooves are respectively formed at the bottom end of the box cover 12 and the upper end of the box body 11. A first magnet ring 16 and a second magnet ring are respectively installed inside the first installation groove and the second installation groove. The first magnet ring 16 and the second magnet ring attract each other magnetically. The first installation groove, the second installation groove, the first magnet ring 16 and the second magnet ring are all in the shape of a "hui" character. Through the coordinated use of the semiconductor refrigeration sheet 13, the heater and the temperature sensor, when the semiconductor refrigeration works, the circular chamber inside the box body 11 is refrigerated. When the heater works, the circular chamber inside the box body 11 is heated. At the same time, by setting the temperature sensor to monitor the temperature inside the circular chamber of the box body 11, the constant temperature environment inside the circular chamber of the box body 11 is maintained. Through the coordinated use of the first magnet ring 16 and the second magnet ring, since the first magnet ring 16 and the second magnet ring attract each other magnetically, magnetic adsorption realizes the quick sealing of the box cover 12 and the box body 11.
[0033] Specifically, the working principle of this liver cancer tissue slice constant temperature preservation box is as follows: During use, a ball screw 27 is used. When the ball screw 27 rotates, the balls roll between the ball screw 27 and the screw nut, pushing the screw nut to move axially along the ball screw 27, thereby achieving linear movement of the lifting platform 28. Through the cooperation of the sliding groove 210 and the sliding strip 26, the sliding groove 210 is set on the wedge block 29 outside the lifting platform 28, and the sliding strip 26 is installed on the inclined surface of the adjusting seat 25. When the lifting platform 28 moves upward or downward, under the sliding connection of the sliding strip 26 and the sliding groove 210, and the contact between the wedge block 29 and the inclined surface of the adjusting seat 25, the adjusting seat 25 smoothly passes through the moving groove 24, thereby causing several adjusting seats 25 to expand outward or contract inward, allowing each... The distance between the aligned adjustment seat 25 and the fixed seat 15 can be reduced or increased to facilitate the placement of liver cancer tissue slices of different sizes. Since vertical grooves are opened at the opposite ends of the fixed seat 15 and the adjustment seat 25, it is convenient to place liver cancer tissue slices formed by the combination of coverslips and slides between a pair of vertical grooves. The lid 12 is closed, so that the lid 12 and the box body 11 are closed under the magnetic attraction of the first magnetic ring 16 and the second magnetic ring. Through the cooperation of the semiconductor cooling chip 13, the heater and the temperature sensor, when the semiconductor cooling is working, it cools the circular cavity of the box body 11. When the heater is working, it heats the circular cavity of the box body 11. At the same time, the temperature sensor is set to monitor the temperature in the circular cavity of the box body 11, thereby maintaining a constant temperature environment in the circular cavity of the box body 11.
