Mechanical arm for shooting bone marrow smears and working method thereof

Abstract

The invention discloses a mechanical arm for shooting bone marrow smears. The mechanical arm comprises an X-direction translation mechanism, a Y-direction translation mechanism, a Z-direction translation mechanism and a base, wherein the X-direction translation mechanism comprises an X-axis mounting plate, an X-direction translation assembly and an X-direction distance measurement assembly; the Y-direction translation mechanism comprises a connecting plate, a Y-axis mounting plate, a Y-direction translation assembly and a Y-direction distance measurement assembly; the Z-direction translation mechanism comprises a Z-axis mounting plate, a Z-direction translation assembly and a Z-direction distance measurement assembly; the X-axis mounting plate is mounted on the base; a connecting plate can slide on the X-axis mounting plate through the X-direction translation assembly; the Z-axis mounting plate can slide on the Y-axis mounting plate through the Y-direction translation assembly; and an electric clamping jaw is mounted on the Z-direction translation assembly and can slide on the Z-axis mounting plate through the Z-direction translation assembly. The invention also discloses a corresponding working method. The mechanical arm can be applied to rapid and accurate movement of bone marrow smears in the X-axis direction, the Y-axis direction and the Z-axis direction; and efficient and high-accuracy image acquisition under low load and low power consumption is achieved.

Description

technical field [0001] The invention relates to the technical field of pathological image acquisition, in particular to a mechanical arm for taking bone marrow smears and a working method thereof. Background technique [0002] At present, in domestic collection of images of pathological slices, such as the shooting of bone marrow smears, most of the slices are placed on the three-dimensional stage, so that the stage also needs to move together during the whole slice scanning process, especially during the focusing process. As a result, the whole process has a large load and low structural rigidity. Therefore, it is difficult to avoid the vibration caused by unstable operation for objects with shallow depth of focus, high repeat positioning accuracy and fast scanning, which will affect the image acquisition accuracy. Contents of the invention [0003] The present invention proposes a mechanical arm for taking bone marrow smears and its working method to solve the above tech...

AI Technical Summary

Problems solved by technology

As a result, the load in the whole process is heavy and the structural rigidity is low. Therefore, it is difficult to avoid the vibration caused by unstable operation for the target with shallow depth of focus, high repeat positioning accuracy and fast scanning, which will affect the image acquisition accuracy.
