Description
Technical Field
The invention relates to the technical field of pathological sample slicing devices, in particular to a quick-freezing type pathological sample slicing device for a pathological laboratory.
Background
The pathological section is made up by using some pathological tissues or organs through the processes of various chemicals and embedding method, fixing and hardening them, cutting them into thin slices by microtome, sticking them on the glass slide, staining with various colours, and examining under the microscope to observe pathological change and make pathological diagnosis.
In conventional tissue preparation, slicing is one of the most important techniques, and the quality of the slicing directly influences the observation effect of the specimen. Good microtomes are an important part of the whole preparation process, and for preparing 1 good section, the pathologist must perfectly combine the technique, knowledge and skill. Firstly, the quality of a sample to be cut is a key factor, and the quality of the sample depends on the accuracy of the preliminary treatment work, including fixation, dehydration, embedding and the like; the correct type of slicer must be selected, along with the appropriate steel knife or disposable blade; the type, size and thickness of the sample need to be carefully considered during slicing, and the convenience and comfort of the operator are considered. Secondly, a high-quality slice is cut out, and a great experience of an operator is essential. The operator must understand the working principle of the microtome and make fine adjustments to the machine to achieve optimal results; common faults can be dealt with, and some potential influence factors are eliminated; whether a steel knife or a disposable blade is used, the cutting edge must be sharp and free of any nicks or foreign matter.
The conventional pathological sample needs to be subjected to multi-step processing operation before being sliced, each operation step is performed separately, a sample slicer is only used for slicing the processed sample, so that the processing time of a sample is inevitably increased, and the sample needs to be labeled in the processing due to the separate processing, markers need to be checked before each step and records are paired one by one, the situation of confusion is placed, the time of the whole processing flow is increased, the operation burden is also increased, and therefore the slicing device centralizes the whole flow on one device is provided, and the complexity in the sample manufacturing process is reduced.
