Description

Adapter device of adaptation frozen section machine and embedded box directly link adapter subassembly Technical Field The invention relates to the technical field of frozen microtomes, in particular to an adapter device for adapting to a frozen microtome and an embedded box direct-connection adapting assembly. Background In pathological diagnosis work, a frozen microtome is a key device for rapid pathological diagnosis in operation, and the frozen microtome can be used for slicing a tissue sample after rapid freezing, so that a timely diagnosis basis is provided for clinical operation. However, there are three significant problems within the industry: Firstly, the device compatibility is poor. The interface specifications of the sample head and the sample holder of the frozen microtome produced by different manufacturers lack unified standards, so that the sample holder cannot be commonly used when the same sample is transported between different devices or cooperatively processed by multiple devices, and the adapting part is required to be frequently replaced or the tissue sample is required to be transferred, thereby not only increasing the operation complexity and the time consumption of work, but also easily causing tissue damage in the transfer process and improving the error risk. Secondly, the specimen identification is not standard. In the frozen section process, the traditional sample support lacks a uniform and stable identification carrier, the pathological numbering is marked by handwriting, labeling and other modes, the problems of missing numbering, blurring, falling off and the like are easy to occur, the sample is confused or archived in error, the accuracy of subsequent diagnosis and the traceability of the sample are seriously influenced, and great hidden danger is brought to pathological quality control work. Thirdly, the sample storage and archiving process is complicated. The residual sample on the sample support is difficult to directly store and keep in a file after frozen section, in the existing operation, the residual sample is required to be taken down from the sample support after frozen section is completed, the tissue is opened in a chemical mode and air-dried, and then the residual sample is transferred into a plastic embedding box for paraffin embedding treatment, so that long-term preservation and archiving can be completed, the whole process is multiple in steps and complex in operation, the labor capacity of workers is increased, the risks of tissue damage and sample confusion are increased in the process of transferring the sample for many times, and the working efficiency of pathological section making is reduced. Therefore, how to systematically solve the three technical problems to simplify the working flow and improve the working efficiency is a technical problem to be solved in the prior art. Disclosure of Invention It is therefore an object of the present invention to provide an adapter for a cryostat that systematically solves the three aforementioned problems by being used with existing universal sample holders and embedding cassettes.
