[0028] A box body 1, the upper end of the box body 1 is open, and the side wall and the lower end of the box body 1 are both provided with a first leakage hole 8 communicating with the inside and the outside;

At the same time, the fixed end is arranged in the side wall of the box body 1 and can also lower the lowest position of the top cover 3 to ensure that the pressing plate 6 can press the pathological tissue.
[0030] The top cover 3 is fixedly connected to the movable end of the lifting mechanism 2, and the top cover 3 is arranged above the opening of the box body 1. The lower end of the top cover 3 is provided with a pressing plate 6, and the top cover 3 and the pressing plate 6 are both provided with a second leakage hole 9; preferably, the top cover 3 is arranged directly above the box body 1, and the surface area of the pressing plate 6 is less than or equal to the upper end opening area of the box body 1 to ensure that the pressing plate 6 can enter the box body 1.
[0031] A transverse clamping mechanism 4, which is disposed in the box body 1 and is slidably connected to the inner wall of the box body 1;
[0032] The longitudinal clamping mechanism 5 includes a horizontal clamping plate 51 and a vertical clamping plate 52. A plurality of vertical clamping plates 52 are provided. The vertical clamping plate 52 and the horizontal clamping plate 51 are detachably connected. The horizontal clamping plate 51 and the transverse clamping mechanism 4 are detachably connected.
[0033] The pathological tissue is clamped around by the transverse clamping mechanism 4 and the longitudinal clamping mechanism 5, and the upper end of the pathological tissue is pressed by the pressing plate 6, so that the pathological tissue will not produce curling that increases the complexity of the pathological operation, and the tissue shrinkage activity that causes secondary tissue damage. The first leakage hole 8 and the second leakage hole 9 on the box body 1, the cover plate and the pressing plate 6 facilitate the circulation of the liquid medicine when soaking in the liquid medicine, thereby improving the liquid medicine soaking effect of the pathological tissue.
[0034] In the present embodiment, specifically, the front and rear side walls of the box body 1 are both provided with a first sliding track 12, the transverse clamping mechanism 4 includes two first telescopic rods 41, two second sliding tracks 42, a clamping plate 43 and a locking bolt 44, the fixed ends of the two first telescopic rods 41 are relatively arranged on the left and right side walls of the box body 1, the movable ends of the two first telescopic rods 41 are respectively connected to a second sliding track 42, the two ends of the second sliding track 42 are respectively slidably connected to the first sliding track 12, the locking bolt 44 is arranged on the outside of the box body 1, and is rotatably connected to one end of the second sliding track 42, the clamping plate 43 and The second sliding rail 42 is slidably connected, and the clamping plate 43 and the horizontal clamping plate 51 are detachably connected; the second sliding rail 42 is locked by screwing the locking bolt 44. When in use, loosen the locking bolt 44, and manually push the two second sliding rails 42 to move along the first sliding rail 12 to contact the left and right sides of the pathological tissue respectively, and then tighten the locking bolt 44. By screwing the locking bolt 44, it is abutted against the outer wall of the box body 1, thereby fixing the second sliding rail 42; the first telescopic rod 41 is set to assist in correcting the deviation of the second sliding rail 42 and prevent the second sliding rail 42 from being skewed during movement.
[0035] In this embodiment, specifically, the transverse clamping mechanism 4 also includes a bidirectional screw rod 45 and a knob 46. The bidirectional screw rod 45 is arranged in the second sliding track 42. One end of the bidirectional screw rod 45 is rotatably connected to the inner wall of the second sliding track 42, and the other end of the bidirectional screw rod 45 passes through the second sliding track 42. The knob 46 is arranged on the outside of the box body 1. The knob 46 and the bidirectional screw rod 45 are fixedly connected, and a clamping plate 43 is respectively arranged on both sides of the bidirectional screw rod 45; the knob 46 is preferably manually operated, and the bidirectional screw rod 45 drives the clamping plate 43 thereon to move relative to each other, thereby driving the longitudinal clamping mechanism 5 to slide to abut against the pathological tissue.
[0036] In this embodiment, specifically, a snap-in slot 53 is provided on the front side of the horizontal card plate 51, a socket slot 54 is provided on the bottom end of the horizontal card plate 51, and a plug plate 10 is provided at the top end of the vertical card plate 52 and the top end of the snap-in plate 43. The plug plate 10 is provided with a bolt hole 11 for passing a first fastening bolt, and the plug plate 10 is plugged into the socket slot 54, and the bolt hole 11 is connected to the snap-in slot 53; the vertical card plate 52 is plugged into the socket slot 54 through the plug plate 10, and the number of vertical card plates 52 on the horizontal card plate 51 is adjusted according to the spacing between the two second sliding rails 42. Preferably, there is a gap between the vertical card plates 52, and the size of the gap is selected according to actual conditions.
[0037] By adjusting the gap size and the number of vertical clamping plates 52, it is possible to adapt to the spacing between any second sliding rails 42. At the same time, the setting of the gap can also facilitate the circulation of the medicine during the immersion process, further improving the medicine immersion effect of the pathological tissue. Preferably, the gap sizes between the vertical clamping plates 52 are the same. Compared with irregular gap settings, uniform gaps can further improve the fluidity of the medicine.
[0038] Preferably, during installation of the vertical clamping plate 52, the clamping slot 53 is located on a side away from the pathological tissue, thereby preventing the first fastening bolt fixing the vertical clamping plate 52 and the clamping plate 43 from directly contacting the pathological tissue and causing damage to the pathological tissue.
[0039] In this embodiment, specifically, the heights of the longitudinal clamping mechanism 5 and the transverse clamping mechanism 4 are both lower than the thickness of the pathological tissue; the heights of the longitudinal clamping mechanism 5 and the transverse clamping mechanism 4 are both lower than the height of the pathological sample to ensure that the pressing plate 6 can press the pathological sample. At the same time, lowering the heights of the longitudinal clamping mechanism 5 and the transverse clamping mechanism 4 is also beneficial to the contact between the liquid medicine and the pathological sample during the immersion process, thereby improving the immersion effect.
[0040] In this embodiment, specifically, a plurality of evenly distributed elastic members 7 are provided between the top cover 3 and the pressing plate 6; by providing the elastic members 7, after the pressing plate 6 presses the pathological tissue, the elastic members 7 will contract to achieve a buffering effect, thereby reducing the possibility of excessive pressure under the pressing plate 6 damaging the pathological tissue, and the elastic member 7 is preferably a spring.
[0041] Both the transverse clamping mechanism 4 and the longitudinal clamping mechanism 5 are lower than the thickness of the pathological tissue. After the pressing plate is pressed down, the lower end of the pressing plate 6 and the top of the transverse clamping mechanism 4 and the longitudinal clamping mechanism 5 will clamp part of the pathological tissue. Under the action of the spring 7, the shrinkage process can keep the pressing plate 6 pressing the pathological tissue, further preventing the pathological tissue from producing a certain activity after shrinking.
[0042] In this embodiment, specifically, the lifting mechanism 2 includes four evenly distributed second telescopic rods, the four second telescopic rods are respectively arranged at the four corners of the box body 1, the fixed end of the second telescopic rod is provided with a second fastening bolt, the movable end of the second telescopic rod is fixedly connected to the top cover 3, and the second telescopic rod is locked by the second fastening bolt. When in use, first loosen the second fastening bolts on the four lifting rods, and then manually press the top plate down, tighten the second fastening bolt after pressing it into place, and lock the second telescopic rod.
[0043] At the same time, there are steps in the use of the pathology box that require it to be completely immersed in the medicine solution. The horizontal clamping mechanism 4, the longitudinal clamping mechanism 5 and the lifting mechanism 2 are all adjusted manually to the corresponding positions, thereby reducing the cost and weight of the pathology box, and avoiding the use of motors and other driving parts to prevent the life of the driving parts from being damaged after being immersed in the medicine solution, or even affecting the quality of the medicine solution and causing the possibility of experimental errors.
[0044] The use of the utility model:
[0045] Loosen the locking bolt 44 on the first telescopic rod 41, manually push the two second sliding rails 42 to move along the first sliding rail 12, respectively contact the left and right sides of the pathological tissue, tighten the locking bolt 44, and lock and fix the second sliding rails 42 through the locking bolt 44;
[0046] According to the spacing between the two second sliding rails 42, the number of vertical clamping plates 52 on the horizontal clamping plate 51 is adjusted, leaving gaps between the vertical clamping plates 52. After the installation is completed, the horizontal clamping plate 51 is placed on the clamping plate 43, and a clamping plate 43 on the second sliding rail 42 is inserted into each side of the horizontal clamping plate 51. After the fixation is completed, it is fixed by the first fastening bolt, and the bidirectional screw rod 45 is driven to rotate by manually tightening the knob 46, thereby driving the horizontal clamping plate 51 to slide until it abuts against the front and rear ends of the pathological tissue.
[0047] After the pathological tissue is abutted all around, first loosen the second fastening bolts on the four lifting rods, then manually press the top plate down, tighten the second fastening bolts after it is pressed down to the right position, and lock the lifting rods to achieve circumferential fixation of the pathological tissue.
[0048] When removing the pathological tissue, just follow the steps in reverse order.
