Background
The slice scanning refers to scanning and splicing the traditional glass slices, and finally converting the traditional glass slices into digital slices. Compared with the traditional glass slice real object, the digital slice has the advantages of flexibility, convenience and low cost in the aspects of slice information storage, management, observation, analysis and the like, so that the slice digitalization has market advantages.
Digital slice scanners place high demands on the autofocus technology of the microscope. The automatic focusing technology of the microscope is realized by adjusting the distance between the focal point of the microscope and the vertical direction of the section. In most scanning systems, the focal length of the microscope objective is very small, and the stability of the slice holding device has a significant effect on the focusing effect of the slice during the autofocus process of slice scanning.
The adverse effect of the slice holding device on the focusing of the slice scan includes the following aspects. Firstly, the slice clamping device centre gripping is cut into slices and is crossed pine or tension, and the pine can lead to the section not hard up excessively, and tension causes the section to damage easily. Secondly, the verticality between the slice clamping device and the objective lens can not be guaranteed, so that the local focusing effect is poor. The traditional slice clamping device usually adopts a mode of directly locking a slice by a mechanical thread to position, fix and lock the slice. The two small iron sheets are connected with the fixed cover plate of the slice clamping device through threads, so that the locking of the slices is realized. Because of the limitation of the optical principle in the precision focusing process of slice scanning, the distance between the microscope lens and the cover glass of the slice is very close. At the same time, two thirds of the area of the section carry information, while the field of view of the microscope is relatively small. The microscope and the slice are required to move relatively, so that full-information and all-directional scanning can be realized. In the process of relative movement of slice information scanning, in a traditional slice clamping structure, namely a slice clamping fixed thread structure, a screw head is easy to collide with a microscope lens.
In order to solve the above problems, the present invention has developed a slice clamping device for slice scanning. The section clamping device can generate interference-free clamping force with proper size in the section scanning process, thereby realizing the research of biological cell tissues applicable to optical microscope imaging, pathology, biomedical diagnosis, life science research and the like.
