Description

Technical Field

[0001] The utility model relates to the technical field of bone grinding slices, in particular to a hard bone grinding slice. Background Art

[0002] Bone slices are the microscopic morphology of bone tissue, such as the shape and size of the Haversian canals, the number of bone plate layers and osteons, and other morphological features that need to be examined using an optical microscope. Therefore, the bones need to be made into thin slices that can transmit light and observe the internal structure. By observing the bone slices, the number of osteons in the cortical bone, the number of old osteons, the thickness of the outer ring osteons, and the number of non-Haverian canals can be examined to determine the species and age of the bones.

[0003] Among them, patent number CN209729145U discloses a hard bone grinding slice for teaching, including a glass slide and a cover glass. The glass slide and the cover glass are interlocked with each other through the cooperation of an insertion rod and a socket. The insertion rod is arranged on the cover glass, and the socket is arranged on the glass slide. A bone grinding slice body is arranged between the glass slide and the cover glass, and the bone grinding slice body is arranged in a placement groove, and the placement groove is arranged on the front side of the glass slide. A buffer strip is arranged on the back side of the cover glass, and the buffer strip abuts against the bone grinding slice body.

[0006] Therefore, the purpose of the utility model is to provide a hard bone grinding slice, which solves the problem that the separation design proposed in the background art leads to cumbersome steps for loading the bone grinding slice and easily causes the loss of accessories.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A hard bone grinding slice comprises a glass slide and a cover glass, wherein the cover glass is installed above the glass slide, rotating rods are provided on both sides of one end of the cover glass, the outer walls of the two rotating rods are sleeved with torsion springs, one end of the two torsion springs are fixedly connected to the rotating rods, bases are fixedly installed on both sides of one end of the glass slide, mounting grooves are provided inside the two bases, the torsion springs are fixedly installed inside the mounting grooves, the two rotating rods are rotatably connected to the base, and a pressing mechanism is provided inside the cover glass.

[0009] Preferably, the pressing mechanism includes a glass pressing plate, a plurality of connecting rods and a plurality of springs, the glass pressing plate is arranged below the cover glass, the plurality of connecting rods are fixedly installed above the glass pressing plate, the plurality of springs are all installed above the connecting rods, a plurality of spring grooves are opened inside the cover glass, the plurality of springs are all fixedly installed in the spring grooves, and the plurality of connecting rods and the spring grooves are slidably connected.

[0012] Furthermore, a handle is fixedly provided on one end of the cover glass.

[0013] Preferably, the four corners of the glass slide are wrapped with anti-collision rubber sleeves.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model makes the cover glass and the slide glass become an integrated design through the rotation connection of the rotating rods on both sides of the cover glass and the base of the slide glass, and then the cover glass and the slide glass are clamped with the bone grinding piece by the torsion spring. Because of the torsion spring, there will be a tilt angle between the cover glass and the slide glass, and the tilt angle is eliminated by the pressing mechanism, thereby reducing the manual steps of loading the bone grinding piece, and can also better make hard bone grinding slices.

[0016] 2. The utility model evenly opens a plurality of spring grooves inside the cover glass, installs a spring and a connecting rod inside each spring groove, and the plurality of connecting rods are connected to the glass pressing plate. Under the action of the springs, the glass pressing plate can be pressed on the bone grinding piece in parallel with the glass slide.

[0017] 3. In the utility model, when manufacturing and using the slicing device, it is necessary to manually break open the cover glass, because the cover glass is made of glass and may be damaged by frequent use. By installing a U-shaped metal frame around the cover glass, the strength of the cover glass is improved, thereby increasing the number of times the slicing device can be used.
