Embedding: The fixed specimens need to be embedded and embedded in wax blocks so that the integrity and stability of the specimens can be maintained during subsequent slicing. Slicing: The embedded specimens are sliced by a pathological slicing machine for easy microscopic observation.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, 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 should not be understood as a limitation on the present invention.
[0024] Example:
[0025] Reference Figure 1-Figure 4A pathological specimen picking and placing clamp comprises two groups of herringbone-shaped splints 1, the ends of the splints 1 are rotatably connected with adjusting plates 2, and the ends of the splints 1 are also fixedly connected with connecting shafts 101 fixedly connected with the ends of the splints 1, a connecting seat 4 is fixedly connected to the adjusting plate 2, and the connecting shaft 101 is rotatably connected to the connecting seat 4, and sliding grooves 5 are provided on the inner walls of the splints 1 and the adjusting plate 2, and a limiting plate 6 is slidably connected in the sliding grooves 5, and the limiting plate 6 can slide to the middle of the junction of the splints 1 and the adjusting plate 2, and extension plates are provided on both sides of the limiting plate 6, and the extension plates are slidably connected in the sliding grooves 5.
[0026] When the device is not used, the limit plate 6 can be pushed upward from the slide slot 5, and the position of the limit plate 6 is moved and adjusted. Figure 4 As shown in the figure, the adjustment plate 2 and the clamping plate 1 can be folded at this time. When the device needs to be used, the position of the limiting plate 6 is changed to move it to the middle of the junction of the clamping plate 1 and the adjustment plate 2, thereby limiting the position of the adjustment plate 2.
[0027] In addition, multiple groups of contact blocks 7 in a trapezoidal shape are fixedly connected to the outside of the clamping plate 1 and the adjusting plate 2, respectively. Figure 2 As shown in the figure, the contact blocks 7 on the splint 1 and the adjusting plate 2 are staggered with each other. When the adjusting plate 2 is rotated to the outer wall of the splint 1, multiple groups of contact blocks 7 are engaged with each other to limit the position. On the one hand, such contact blocks 7 can make it easier for medical staff to contact the splint 1, increase the friction of the outer wall of the splint 1, provide better grip and anti-slip properties, and make the operation more stable and safe. On the other hand, it can also make the adjusting plate 2 engage with the splint 1 to form a superimposed state, so that it can completely protrude to the surface of the desktop, which is more conducive to the medical staff to take the splint 1 placed on the desktop again.
[0028] In addition, a chuck piece 3 is detachably connected to the inner wall of the adjustment plate 2, and the chuck end of the chuck piece 3 can extend to the outside of the adjustment plate 2, and the surfaces of the chuck piece 3 and the adjustment plate 2 are parallel to each other, which can ensure that the clamping direction of the chuck piece 3 is consistent with the adjustment plate 2, and a placement groove 201 is opened on the adjustment plate 2, and a screw 202 is fixedly connected in the placement groove 201, and a through hole is opened in the middle of the chuck piece 3, and the chuck piece 3 is connected to the screw 202 through the through hole, and a locking nut 203 is threadedly connected to the screw 202, which can be used to lock or disassemble the chuck piece 3.
[0029] The two ends of the chuck piece 3 are respectively fixedly connected with a pointed chuck 301 and a flat chuck 302. In addition, a slender chuck and a blunt chuck can be fixed at the two ends of the chuck piece 3, which can be changed according to the needs of medical staff. When medical staff take and place pathological specimens, they need to perform appropriate fixation treatment, usually using chemical reagents such as formalin to maintain the morphology and structure of the tissue. Embedding: The fixed specimen needs to be embedded in a wax block so that the integrity and stability of the specimen can be maintained during subsequent slicing. Slicing: The embedded specimen is sliced by a pathological slicing machine for easy microscopic observation.
[0030] Secondly, the pointed chuck 301 on the chuck sheet 3 is suitable for clamping thinner pathological specimens, such as cytological specimens or thin-layer tissue sections. The pointed design can clamp thin and fragile specimens more easily to avoid damaging the specimens, and the flat chuck 302 is suitable for clamping thicker pathological specimens, such as tumor tissue or bulk tissue specimens. The flat head design can provide a wider clamping area and more uniform pressure to ensure clamping stability, and the slender chuck is suitable for clamping slender specimens, such as tubular tissue or cells. The slender head design can clamp and control slender specimens more easily to avoid sliding or deformation, and the blunt chuck is suitable for clamping thicker and harder specimens, such as bone tissue or hard nodules. The blunt head design can provide a stronger clamping force to ensure clamping firmness, and then a double set of chucks of different styles can be used to adapt to the use of pathological specimens of different thicknesses, reduce economic costs, and the applicable chuck will not cause damage or deformation of the specimen to improve the practicality of the device.
[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
