Pathological diagnosis specimen preparation device

Abstract

The invention relates to the technical field of microorganisms, in particular to a pathological diagnosis specimen preparation device which comprises a specimen preparation box. A specimen preparation assembly is arranged in the specimen preparation box, and a specimen displacement control part is arranged on the specimen preparation box; the specimen preparation assembly comprises a cross table, the cross table is formed by vertically crossing two support plates, and the support plates are respectively connected with the inner wall of the specimen preparation box; a sample box, a washing box, a containing table and a chute are sequentially arranged at the ends of the two support plates; a self-sealing bag opening part and a self-sealing bag closing part are arranged in the sample box; a first formaldehyde purification part and an auxiliary cleaning part are arranged in the cleaning box; opening and closing doors are respectively arranged at positions, corresponding to the sample box, the washing box, the containing table and the chute, on the specimen preparation box; the specimen displacement control part comprises a stepping motor, a first electric telescopic rod and a grabbing piece. A specimen making and storing device capable of reducing the toxic action of formalin is provided, and meanwhile, the purpose of safely and manually cutting specimens is achieved.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a pathological diagnosis specimen making device. Background technique [0002] Pathological diagnosis is a method for diagnosing diseases by performing fixed staining on tumor specimens removed during surgical resection or autopsy, and then performing histological examination under a microscope; Based on the observation of changes, etc., the cause of the disease, the pathogenesis, the morphological structure of the diseased body during the disease process, the change of functional metabolism and the outcome of the disease are studied, so as to diagnose and treat the disease. Pathological diagnosis is a disease diagnosis made by observing the gross (macroscopic) changes of organs, and observing the tissue structure and cell pathological characteristics under a microscope. Multiple diagnoses or possible diagnoses) and the diagnosis made by various images (such as ultrasound...

Problems solved by technology

[0003] The most important thing in the process of pathological diagnosis is the collection and production of surgical specimens. In the process of specimen preparation, it is necessary to manually remove the tissue samples from the formalin solution, and then manually cut the tissue samples to obtain the required specimens. , put the specimen into the embedding box and dehydrate it to obtain the required specimen sample; and the remaining tissue samples after cutting are returned to the formalin solution for fixation and preservation; during this operation, it is necessary to manually clean the tissue The sample is taken, placed and cut, and it is inevitable to contact a large amount of formalin during this operation; formalin is an aqueous solution of formaldehyde, generally containing 37-40% formaldehyde gas, and its appearance is colorless and transparent, with Corrosive, because the formaldehyde contained in it is extremely volatile, and it emits a strong pungent smell after opening the bottle; many scientific studies and animal experiments have pointed out that long-term exposure to formalin may cause cancer, and it has been listed as a A "suspected carcinogen". A small amount of formaldehyde metabolizes quickly in the human body, and its residue is not strong. About 35% of it can be metabolized into formic acid, which is excreted in the form of formate in the urine, and the remaining 65% can continue to be metabolized. It is used to remove carbon dioxide and water, but the biggest problem is that it may cause cell denaturation, and bacteria, human isolated cells, or animal cell gene mutation tests are positive, and the possibility of causing biological deformities cannot be ruled out; in addition, according to many medical reports. , if the human skin directly contacts formalin, it may cause allergic reactions, dermatitis or eczema, especially for people who need to contact formalin for a long time at work, such phenomena often occur. It can be seen that for long-term work For the staff who make pathological diagnosis specimen samples, long-term exposure to formalin will cause extremely adverse effects on health

[0004] The prior art discloses "a specimen preparation and preservation device", the application date is December 10, 2015, and the application number is "201510915145.1", which specifically discloses the following technical features: including specimen preparation head, top-opening liquid sample chamber and specimen storage box, which uses a specimen preparation head to cut specimens, and those skilled in the art know that pathologists can effectively judge whether pathological changes occur in tissues and organs after mastering histology, embryology and normal anatomical structures of the human body. There are many forms, such as tumor, verification, hemorrhage, infarction, etc., and even the same pathological change, its performance in different tissues and organs is also very different, so when sampling specimens, it is necessary to master the pathobiology and pathology Doctors perform selective cutting, so the above-mentioned technical solutions disclosed in the prior art carry out cutting with a specific scale, which is of little significance to the preparation of pathological diagnosis specimens
