Description
Technical Field
The utility model relates to a section clamping device, concretely relates to section clamping device for section scanning. The utility model is suitable for a field such as optical microscope formation of image, pathology, biomedical diagnosis, life science research.
Background
The slice scanning refers to scanning and seamless splicing of traditional glass slices to generate a full-view digital slice. Through computer and network system, digital slice storage, management, observation, analysis, discussion, etc. are carried out. Compared with the traditional mode, the method is not limited by space and time, is more convenient to use, has stronger functions and is more widely applied. With the digital section, a new application direction is certainly injected for teaching, pathological diagnosis, remote consultation, scientific research and the like.
The digital slice scanning refers to the automatic scanning of the traditional glass slice under a certain multiplying power by combining a microscope and a motion platform with an automatic operation technology. The microscope automatically scans the whole section in a full-information and all-round way, so that the appearance of the traditional section is converted into a digital image.
Digital slice scanning devices are mainly related to three aspects of technology: the automatic focusing technology of the microscope, the focusing technology of the moving platform and the image processing technology. The automatic focusing technology of the microscope is realized by adjusting the distance between the focal point of the microscope and the section in the vertical direction, and the focusing technology of the moving platform is realized by connecting the moving platform with the space motion of the section, so that the whole section is scanned in all directions in full information.
In most scanning systems, the focal length of the microscope objective is very small. In the auto-focusing process of slice scanning, the key and difficulty is the focusing of the slice. The centering of light path, the stability of motion platform, the stability of section clamping device all can produce very big influence to sliced focus effect.
Many aspects of the slice clamping device clamping the slice have a non-negligible effect on the focus of the slice scan. Wherein the slice clamping device can not clamp the slice or damage the slice due to too tight clamping for design reasons, resulting in poor slice scanning effect. In addition, the conventional slice clamping device usually adopts a cantilever type structure, most of the structure for bearing the slices is suspended, and no support is provided. The entire slice holding device may be inclined downward along the suspended portion under the influence of gravity. The parallelism of the whole section relative to the microscope lens can not be ensured, and great influence is generated on the focusing and the final scanning imaging in the scanning process of the section.
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.
The magnitude of the applied clamping force is completely artificially controlled. If the clamping force is too large, the slide may be damaged. Affecting the imaging effect of the slice scan and even damaging the information carried by the slice.
The utility model discloses in the face of above-mentioned demand, through design ingeniously. One side of the slice is fixed, the other side of the slice is clamped tightly through the slice clamping elastic sheet, and the thread structure is distributed on the innovative design of the edge of the slice clamping fixed cover plate, so that the slice clamping device for slice scanning is developed. 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.
