Technical Field

[0001] This utility model belongs to the technical field of cryosectioning devices, specifically relating to a pathological tissue cryosectioning device. Background Technology

[0002] Cryosectioning devices are integrated equipment systems used in pathology to rapidly prepare ultrathin sections from fresh biological tissues in a low-temperature, constant-temperature environment. Their core function is to provide technical support for rapid intraoperative pathological diagnosis by maintaining a constant low-temperature environment to reduce ice crystal damage and maintain tissue rigidity, thereby achieving rapid sectioning.

[0003] Currently, existing cryosection devices require medical personnel to open the device cover after sectioning, remove the tissue slices, and place them on a glass slide. However, because the tissue slices are relatively thin, they are easily damaged during the removal process. To address this issue, we provide a pathological tissue cryosection device. Utility Model Content

[0009] As a preferred embodiment, a T-shaped slider is slidably connected inside the T-shaped groove, and the right side of the T-shaped slider is fixedly connected to the left side of the moving plate.

[0010] As a preferred embodiment, the inner wall of the flip plate is threaded with two threaded shafts, and each of the two threaded shafts is fixedly connected to a fixing pad at one end close to the other. The two fixing pads are respectively in contact with the front and back sides of the glass slide.

[0011] As a preferred embodiment, each of the two threaded shafts is fixedly connected to a rotating plate at one end that is far apart from the other, and the outer surface of each rotating plate is covered with a layer of rubber.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) By utilizing the rotatable nature of the first spiral cylinder, the flip plate fixed on the outer surface of the first spiral cylinder and the glass slide inside the flip plate can cover the sample that has been sliced.

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] Please see Figures 1 to 6 As shown, this utility model embodiment provides a pathological tissue cryosection device, specifically including a slicing device body 1. An automatic mounting mechanism 2 is provided inside the slicing device body 1. The automatic mounting mechanism 2 specifically includes a moving plate 202. A first spiral cylinder 206 is rotatably connected to the inner wall of the moving plate 202. A flipping plate 201 is fixedly connected to the outer surface of the first spiral cylinder 206. A glass slide 205 is provided inside the flipping plate 201. A first hydraulic rod 204 is fixedly connected to the inner wall of the slicing device body 1. A first spiral shaft 203 is fixedly connected to the telescopic end of the first hydraulic rod 204. In this embodiment, the moving plate 202 slides within the T-shaped groove 402 via the T-shaped slider 403, moving the glass slide 205 above the sample slice. Then, the first hydraulic rod 204 is activated, and its telescopic end pushes the first spiral shaft 203 into the first spiral cylinder 206. Utilizing the cooperation between the surface stripes of the first spiral shaft 203 and the grooves on the inner wall of the first spiral cylinder 206, the first spiral cylinder 206 rotates 90 degrees clockwise, causing the flipping plate 201 to flip and cover the glass slide 205 onto the sample slice. This achieves the purpose of reducing contact between medical personnel and the sample, and reducing the probability of damage.

[0018] Please see Figure 3 and Figure 4As shown, the slicing device body 1 has an anti-rolling component 3 inside. The anti-rolling component 3 includes a rotating shaft 304, a baffle 301 fixedly connected to the outer surface of the rotating shaft 304, and a blade 306 fixedly connected to the outer surface of the slicing device body 1. The blade 306 facilitates sample slicing. A second hydraulic rod 302 is fixedly connected to the inner wall of the slicing device body 1. A second spiral shaft 305 is fixedly connected to the telescopic end of the second hydraulic rod 302. A second spiral cylinder 303 is fixedly connected to one end of the rotating shaft 304 near the second hydraulic rod 302. The second spiral shaft 305 is slidably connected inside the second spiral cylinder 303. By setting up the second spiral shaft 305 and the second spiral cylinder 303, and utilizing the sliding connection between the second spiral shaft 305 and the second spiral cylinder 303, the second spiral shaft 305 can drive the second spiral cylinder 303 to rotate when it moves.

[0019] Please see Figure 4 As shown, the slicing device body 1 is internally equipped with limiting components 4. Each limiting component 4 includes a fixing plate 401, the bottom surface of which is fixedly connected to the outer surface of the slicing device body 1. A T-shaped groove 402 is formed on the right side of the fixing plate 401. By providing the fixing plate 401 and the T-shaped groove 402, the fixing plate 401 can provide positional limitation for the sliding of the moving plate 202. A T-shaped slider 403 is slidably connected inside the T-shaped groove 402. The right side of the T-shaped slider 403 is fixedly connected to the left side of the moving plate 202. By providing the T-shaped slider 403, the sliding characteristic of the T-shaped slider 403 within the T-shaped groove 402 can limit the movement of the moving plate 202.

[0020] Please see Figure 6 As shown, the inner wall of the flip plate 201 is threadedly connected to two threaded shafts 405. Each threaded shaft 405 has a fixing pad 404 fixedly connected to its closest point. The sides of the fixing pads 404 that are close to each other contact the front and back of the glass slide 205, respectively. With the threaded shafts 405 and fixing pads 404, the threaded shafts 405 can push the fixing pads 404 to move, thus compressing and fixing the glass slide 205. Each threaded shaft 405 has a rotating plate 406 fixedly connected to its furthest point. The outer surface of each rotating plate 406 is covered with a layer of rubber. The rotating plates 406 facilitate the transmission of power to the threaded shafts 405.

[0021] In this invention, during slicing, the rotating plate 406 first rotates the threaded shaft 405, causing the fixing pad 404 to clamp the glass slide 205 and fix it inside the flipping plate 201. Then, the frozen sample is installed in the fixture above the blade 306. Subsequently, the slicing device body 1 can be controlled to adjust the position of the fixture. After the fixture position is adjusted, slicing can be performed with the blade. After the specimen slice is cut, the second hydraulic rod 302 can be controlled to run. The operation of the second hydraulic rod 302 will pull the second spiral shaft 305 forward. The spiral stripes on the surface of the second spiral shaft 305 will correspond to the spiral grooves opened in the second spiral cylinder 303, thereby driving the second spiral cylinder 303 to rotate. Therefore, the second spiral cylinder 303 will eventually rotate 90 degrees counterclockwise. As the second hydraulic rod 302 continues to contract, the second spiral shaft 305 will interact with the second spiral shaft 306. When the inner wall of the first spiral cylinder 303 comes into contact with the second spiral cylinder 303, the second spiral shaft 305 transmits power to the second spiral cylinder 303. The second spiral cylinder 303 then drives the moving plate 202 to slide. Therefore, it is understood that the friction between the second spiral shaft 305 and the second spiral cylinder 303 is less than the friction between the surface of the T-shaped slider 403 and the fixed plate 401. The moving plate 202 slides within the T-shaped groove 402 via the T-shaped slider 403, moving the glass slide 205 above the sample slice. Then, the first hydraulic rod 204 is activated, its telescopic end pushing the first spiral shaft 203 into the first spiral cylinder 206. Utilizing the fit between the surface stripes of the first spiral shaft 203 and the groove on the inner wall of the first spiral cylinder 206, the first spiral cylinder 206 rotates 90 degrees clockwise, causing the flipping plate 201 to flip, covering the glass slide 205 onto the sample slice. This reduces contact between medical personnel and the sample, lowering the chance of damage.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
