Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pathological specimen production, in particular to an adjustable fixator for taking bone tumor pathological specimens. Background Art
[0002] Bone tumors are tumors that occur in bones or their accessory tissues, which can be divided into benign and malignant. Benign bone tumors are easy to cure and have a good prognosis. Malignant bone tumors develop rapidly, have a poor prognosis, and a high mortality rate. When making a pathological diagnosis of bone tumors, the diseased tissue needs to be processed through many procedures to make a specimen glass slide, and the morphology of the diseased tissue is observed under a microscope to obtain a correct diagnosis.
[0003] During the production of pathological specimens, a certain size of diseased tissue needs to be taken and made into a pathological section by histological methods. During the production process, the diseased tissue is first taken and placed on a glass slide, then certain processing is carried out on it, and finally, it needs to be sealed to make a glass slide specimen. When sealing, the upper glass slide needs to be limited and fixed to ensure that it does not shift. Moreover, the sizes of the glass slides required for different pathological specimen situations are also different. In the pathological department, there is no adjustable fixing device for fixing the upper glass slide. Content of the Utility Model

Specific implementation manners
[0021] Next, in combination with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Embodiment 1
[0023] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, an adjustable fixator for taking bone tumor pathological specimens includes a base 1, a fixing plate 2 is fixedly connected to the base 1, not less than one and evenly arranged specimen preparation grooves 5 are provided in the fixing plate 2, a stroke through groove 6 is provided above the specimen preparation grooves 5 in the fixing plate 2, a moving long rod 7 is slidably arranged in the stroke through groove 6, a holding plate 8 cooperating with each specimen preparation groove 5 is fixedly connected to the moving long rod 7, arc-shaped grooves are provided on the holding plates 8 to facilitate grasping and pressing the holding plates 8, electric push rods are provided in the holding plates 8, pressing plates 17 cooperating with the upper glass slides are fixedly connected to the lower ends of the electric push rods, a back plate 3 is fixedly connected to the upper end of the fixing plate 2, not less than one and evenly arranged placement racks 4 are provided on the back plate 3, and other items can be placed on the placement racks 4.
[0024] With the above structure, the upper glass slide can be pressed by using the electric push rod in cooperation with the pressing plate 17. If the position of the moving long rod 7 is fixed, the specific structure is as follows:
[0025] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, limiting moving plates 9 are fixedly connected to both ends of the moving long rod 7, fixed limiting plates 10 are fixedly connected to both sides of the base 1, plate body stroke grooves 11 cooperating with the limiting moving plates 9 are provided in the fixed limiting plates 10, the surface of the limiting moving plate 9 is attached to the inner wall of the plate body stroke groove 11, sliding rods are fixedly connected to the fixed limiting plates 10, rod body stroke grooves 12 cooperating with the sliding rods are provided on one side of the plate body stroke groove 11 in the fixed limiting plates 10, a threaded rod 13 is fixedly connected to one end of the sliding rod, and a locking nut 15 cooperating with the fixed limiting plate 10 is threadedly connected to the threaded rod 13.
[0026] With the above structure, the position of the moving long rod 7 can be fixed.
[0027] Embodiment 2
[0028] AsFigure 1 and Figure 2 As shown in Figure 2 , one end of the locking nut 15 is fixedly connected with a handle 14, and a rotating rod 16 is fixedly connected to the locking nut 15.
