Take a certain size of the lesion tissue biopsy report, prepared by histological methods [usually pathological lesions embedded in paraffin blocks, the use slicer sliced, then hematoxylin - eosin (HE) staining ], further examination with a microscope lesions. Lesions occur in the development process, and finally make a pathological diagnosis. The production of the part or the diseased tissue and organs through a variety of chemical methods of treatment buried, so that the fixed cured, sliced ??on a microtome, adhered on a glass slide, stained with various colors, for under the microscope check to observe pathological changes, make the pathological diagnosis, provide help for clinical diagnosis and treatment. To cut and a knife slicing, first of all have a sharp knife. Brothers is engaged in one of the most fundamental and technical personnel slice biopsy techniques, knife grinding good or bad, is directly related to the quality of the slice. Sharpening the way everyone is different, but they all require force uniform, so that the knife-edge and full access to the grindstone, both hands firmly on the blade should point, rather than on the back of a knife. Knife grinding application once again, only 10 to 15 minutes each, over a long period of sharpening, easy to grind the blade has worn away, check whether the sharp knife and try to touch the knife-edge method of hand is not very Science, not only can not prove that the knife is really sharp, and easy to damage the blade, the easiest way is to try to get a wax block cut after a good look at each mill. After each wear a good knife should grindstone biopsy cover with a lid to prevent dust off the grindstone, with gray grindstone sharpening, knife will produce many small gaps. Many units now have bought Grinder, Grinder for opening blade and grinding gap really good, but because of the angle and time is not easy to accurately grasp the knife, so the effect is not ideal. Based on our experience biopsy What does it mean, really difficult to use the machine's blade grinding out. Disposable blade largely solved this problem. As with disposable blades, blade must be replaced. A knife cut into small samples should not exceed 20 to 25 wax block, cut into large specimens should not exceed 10 to 15 wax blocks.
