Description

technical field [0001] The invention relates to the technical field of pathological tissue sections, in particular to an automatic dewaxing antigen retrieval system. Background technique [0002] Paraffin section is the most widely used method in routine histological preparation techniques. In pathological technical work, whether the paraffin sections are subjected to conventional HE staining or other special staining, it is necessary to remove the paraffin of the paraffin sections, that is, dewaxing. The dewaxing method of paraffin sections is generally to treat the paraffin sections with different reagents in a specific order, and the treatment process usually involves reagent concentrations and temperatures. [0003] At present, there are three main methods for dewaxing paraffin sections: [0004] 1. Manual method: Chinese patent CN 1975367A proposes a method for dewaxing tissue paraffin sections, which involves various reagents and reaction vessels, and involves the co...

Problems solved by technology

Its shortcomings and shortcomings are: (1) real-time monitoring is required by professionals, and the steps are cumbersome, inefficient, and high labor costs are required; (2) some reagents in the dewaxing reaction process not only pollute the environment but are also harmful to the human body ; (3) The reaction vessel and the hanging basket are generally general-purpose, and a large amount of reagents will be wasted in the process of processing, further increasing the cost

[0005] 2. Mechanical arm method: Chinese patent CN261023Y proposes a multifunctional pathological slice processor. This method uses a mechanical boom, which drives the movement of a hanging basket equipped with tissue paraffin sections, and puts the hanging basket into each reaction section in turn. The disadvantages and shortcomings of the reaction in the container are: (1) the prob
