Description

Technical Field

[0001] This utility model belongs to the field of slide-assisted positioning technology, specifically relating to a tumor slide positioning device. Background Technology

[0002] The core function of tumor slides is to clarify the nature (benign or malignant), specific type (e.g., carcinoma, sarcoma, or lymphoma), and stage of the tumor through microscopic observation and analysis of cell morphology, arrangement, and tissue structure. This provides direct evidence for clinical treatment plans (surgical scope, chemotherapy drug selection, or targeted therapy). Furthermore, slide results can assess tumor invasiveness, metastatic risk, and prognosis, and can assist in molecular testing (e.g., gene mutation analysis) to further guide personalized treatment. The conclusions are considered the "gold standard" of pathological diagnosis, directly influencing treatment decisions and efficacy evaluation.

[0003] A known patent application with application number 202222729676.7 discloses a tumor sample slicing positioning device: a base plate, one end of which is movably connected to a placement plate for placing tumor samples via a hinge. Rectangular grooves are formed around the four sides of the placement plate, and guide rails are fixedly connected to each of the four rectangular grooves. First sliders are symmetrically slidably connected to the left and right guide rails, and second sliders are symmetrically slidably connected to the front and rear guide rails. The second sliders are equipped with second baffles that can slide up and down, and the first sliders are equipped with first baffles that can slide up and down. This invention adjusts the positions of the second and first baffles by sliding the second and first sliders along the guide rails, thereby adjusting the size of the slicing space formed between the second and first baffles. This allows for the fixing of tumors of different sizes, and then the tumor is cut along the vertical direction of the placement plate.

[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: When in use, the two sets of baffles are misaligned, making it difficult to ensure stability during clamping time. Using a fixed limiting length to position the baffles on both sides makes it difficult to correctly position the slice in special circumstances. After long-term use, gaps are very likely to appear. Therefore, a tumor slice positioning device is proposed to solve the above problems. Utility Model Content

[0005] This invention proposes a tumor slice positioning device, which solves the problems in related technologies where the misalignment of the two sets of baffles during use makes it difficult to ensure stability during clamping. Using a fixed limiting length to position the baffles on both sides makes it difficult to correctly position the slice under special circumstances, and gaps are likely to appear after long-term use.

[0006] The technical solution of this utility model is as follows: a tumor slice positioning device, comprising: a device plate, a fixing plate, a placement plate and a clamping frame, wherein the placement plate is rotatably connected to a plurality of fine-tuning screws, and the outer wall of the device plate is fixedly connected to a plurality of threaded grooves, wherein the fine-tuning screws are threadedly connected to the inner wall of the threaded grooves.

[0007] The clamping frame is fixedly connected to the outer wall of the placement plate. The outer peripheral wall of the clamping frame is provided with a side moving groove and a fixed groove. Multiple limiting blocks are slidably connected inside the side moving groove.

[0008] The inner wall of the limiting block is fixedly connected to a first clamping rod, the first clamping rod having a through groove inside, and the inner wall of the limiting block is fixedly connected to a second clamping rod, the second clamping rod passing through the through groove.

[0009] Preferably, the upper wall of the limiting block is provided with a fixing buckle, and the extension rod of the fixing buckle passes through the fixing groove.

[0010] Preferably, the inner wall of the device plate is threaded with a plurality of leveling bolts, and the outer wall of the fixed plate is fixedly connected with a plurality of rotating seats, the ends of the leveling bolts being sleeved on the inner wall of the rotating seats.

[0011] Preferably, a first level is fixedly connected to the side wall of the device plate, and a second level is fixedly connected to the side wall of the device plate, wherein the first level and the second level are set perpendicularly to the same horizontal plane.

[0012] Preferably, a laser scribing device is fixedly connected to the lower wall of the device plate. The laser scribing device is a plumb bob, and the output light of the laser scribing device is on the same plane as the outer wall of the clamping frame.

[0013] Preferably, a backlight is fixedly connected to the outer wall of the device plate, and the backlight is located at the center of the clamping frame.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] The combined arrangement of two sets of clamping rods makes the device more secure and stable when clamping slices. The second clamping rod passes through the first clamping rod, allowing the first and second clamping rods to clamp the slices more effectively. This avoids the instability caused by gaps forming between the staggered clamping rods during long-term use. The fixing buckle allows the limiting block to be clamped to the clamping frame when needed, enabling stepless fixing of the two sets of limiting rods and accommodating a wider range of slices.

If it is unbalanced, adjust the angle of the placement plate 3 by rotating the fine adjustment screw 15 so that the horizontal frame 4 is in a horizontal state. Then move the two sets of clamping rods to the outermost position, then first clamp the slice with the second clamping rods 8 on both sides, then bend the fixing buckle 10 so that the fixing buckle 10 and the clamping frame 4 cooperate with each other to fix the two second clamping plates 8. Then clamp the upper and lower ends of the slice with the two first clamping rods 7, and fix the slice completely with the fixing buckle 10. After fixing, turn on the backlight 12 so that the shape of the slice can be observed more clearly when performing subsequent work.

[0028] Furthermore, a fixing buckle 10 is provided on the upper wall of the limiting block 11, and the extension rod of the fixing buckle 10 passes through the fixing groove 6.

[0031] Specifically, the angle of the device plate 1 can be adjusted by adjusting the leveling bolt 15 to avoid deviation between the observed structure and the actual structure due to the angle of the device plate 1 during use.

[0032] Furthermore, a first level 17 is fixedly connected to the side wall of the device plate 1, and a second level 18 is fixedly connected to the side wall of the device plate 1. The first level 17 and the second level 18 are set vertically on the same horizontal plane.
