[0029] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the specified features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0031] In the description of this utility model, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the Figure 1 The orientation and position of the pathological specimen fixation device shown when normally placed are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0033] The utility model provides a pathological specimen fixing device, see Figure 1 , including multiple hooks 100, a traction mechanism 200 and a control mechanism 300. The specimen is hooked on all sides by the multiple hooks 100, and the traction mechanism 200 is driven to move by the control mechanism 300, so that the hooks 100 pull the specimen to the four sides and fix the specimen.

[0034] In one embodiment, see Figure 1-Figure 3 The traction mechanism 200 includes a guide device 210 and a linkage device 220. The guide device 210 is used to limit the moving direction of the hook 100, so that the hook 100 is stretched in a fixed direction to unfold the sample. The linkage device 220 is used to pull the hook 100 at the same time to unfold the entire specimen at the same time.

[0035] In one embodiment, see Figure 2 and Figure 4 The linkage device 220 includes a rotating shaft 221, a rotating disk 222, a plurality of connecting rods 223, and a plurality of movable plates 224. The rotating shaft 221 is mounted at the rotation center of the rotating disk 222. One end of the connecting rod 223 is rotatably connected to the rotating disk 222, and the other end of the connecting rod 223 is rotatably connected to the movable plate 224. The rotating shaft 221 serves as the rotation center of the rotating disk. The rotation of the rotating disk drives the connecting rods 223 to pull the movable plates 224, thereby causing all the connecting rods 223 and movable plates 224 to move.

[0036] For example, the shape of the turntable 222 is circular, square, polygonal, etc., which is not limited in the present invention. For example, in this embodiment, the turntable 222 is hexagonal.

[0037] For example, the number of connecting rods 223 and movable plates 224 is set correspondingly, and the number is 3-8, which is not limited by the present invention. For example, in this embodiment, the number of connecting rods 223 and movable plates 224 is 6, and the connecting rods 223 are connected to the apex of the rotating disk 222.

[0038] Exemplarily, the connecting rod 223 and the rotating disk 222 are hinged, and the connecting rod 223 and the movable plate 224 are hinged.

[0039] Exemplarily, a guide member is provided under the movable plate 224 so that the movable plate 224 moves in a guided direction.

[0040] In one embodiment, see Figure 1 and Figure 3The guide device 210 includes a guide plate 211 and a plurality of sliders 212. One end of the slider 212 is fixed to the movable plate 224, and the other end is located outside the guide plate 211. The guide plate 211 is provided with a plurality of guide grooves 214, along which the sliders 212 slide. When the movable plate 224 moves, the sliders 212 slide along the guide grooves 214, pulling the retractor 100 fixed to the slider 212 outward, so that the retractor 100 can unfold the specimen.

[0041] Illustratively, the guide device 210 further includes a rod 213 , which is fixed to the slider 212 , and one end of the retractor 100 is fixed to the rod 213 to increase the height of the retractor 100 .

[0042] In one embodiment, see Figure 1 The pathological specimen fixing device further includes a vessel 400. A groove is provided on one side of the guide plate 211. The vessel 400 is installed in the groove. The vessel 400 is used to place the specimen.

[0043] In one embodiment, see Figure 1-Figure 2 The pathological specimen fixing device further includes a protective mechanism 500, which includes a transparent box 510 and a transparent cover 520 covering the top of the transparent box 510. The traction mechanism 200 is installed in the transparent box 510. The specimen is placed in the protective mechanism 500 for easy movement to avoid contamination.

[0044] In one embodiment, see Figure 2 The pathological specimen fixing device further includes a support plate 600 , which is mounted on the periphery of the linkage device 220 and is used to support the guide plate 211 so that there is space between the guide plate 211 and the linkage device 220 without affecting the movement of the linkage device 220 .

[0045] In one embodiment, see Figures 1-4 The control mechanism 300 includes a threaded rod 310 and a threaded seat 320. The threaded seat 320 is fixed to the movable plate 224. One end of the threaded rod 310 is threadedly connected to the threaded seat 320. A bearing 511 is provided on the side wall of the transparent box 510. The other end of the threaded rod 310 passes through the bearing 511 and is located outside the transparent box 510. When the threaded rod 310 is rotated, the threaded rod 310 and the threaded seat 320 cooperate to pull the movable plate 224. The movable plate 224 pulls the connecting rod 223, which then rotates the turntable 222, thereby driving the other connecting rods 223 to pull the movable plate 224, which in turn drives the slider 212 to slide, pulling the retractor 100, so that the specimen is pulled apart and fixed. The cooperation between the threaded rod 310 and the bearing 511 can keep the retractor 100 stable, and thus keep the specimen stable.

[0046] In one embodiment, see Figures 1-4The control mechanism 300 further includes a rocker 330, which is connected to the threaded rod 310. The rocker 330 rotates to drive the threaded rod 310 to rotate, thereby completing the opening of the hook 100.

[0047] The specific implementation is as follows: place the specimen in the vessel 400, hook the specimen with the retractor 100, and rotate the rocker 330 to make the threaded rod 310 control the threaded seat 320 to drive the movable plate 224 to move. The connecting rod 223 on this movable plate 224 drives the rotating disk to rotate, and then drives the remaining movable plates 224 to move, so as to achieve the purpose of controlling the distance between the retractors 100. The specimen can be pulled and stretched in all directions at the same time. The cooperation between the threaded rod 310 and the bearing seat 511 can keep the retractor 100 stable, and then keep the specimen stable, thereby playing a role in fixing the specimen.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
