Description
Technical Field
The invention relates to the field of medical equipment, in particular to a diagnostic instrument for early gastrointestinal tumors.
Background
At present, digestive system tumors such as esophagus cancer, gastric cancer, colorectal cancer and the like become clinically high-incidence diseases, and early diagnosis and early treatment have very important significance for prolonging the survival time of patients and reducing the death rate. The fecal examination is an effective means of clinical examination and the most common method for general survey, and has the characteristics of simplicity, convenience, easy operation, low cost, no wound and suitability for large-scale crowd screening. With the development of molecular biology, early screening of gastrointestinal tumors by fecal examination is attracting increasing attention. Calprotectin (CPT), for example, was first isolated from neutrophils by Fagerhol in 1980 and was named L1 protein, after which it was found to contain calcium in its structure and to have antimicrobial properties. Heterodimers are formed by the non-covalent association of two heavy chains 14 and one light chain 8, each chain being capable of binding two calcium ions; and has the capability of chelating zinc ions to have heat resistance. Calprotectin is a heterozygous calcium-binding protein, has protease resistance activity in the presence of calcium ions, is stable in the intestinal cavity and the external environment for a long time, and is not damaged by various enzymes and bacteria; is an important protein in the cytoplasm of neutrophils and activated macrophages and can be used as a marker for the activation of acute inflammatory cells; it is extremely stable in feces and is superior to the prior feces marker. Foreign research shows that the content of calprotectin in feces is obviously increased during UC activity, the activity change of the UC can be dynamically reflected, the histological change in the activity period presents the characteristic of coexistence of acute and chronic inflammations, and the neutrophil granulocytes are considered as a key index for distinguishing the acute and chronic inflammations of the UC. The sensitivity of calprotectin to adenomas is 55%, while the sensitivity of FOB to adenomas is only 10%, the detection of calprotectin has higher value for early detection of adenomas, because the malignant transformation period of adenomas is 5-7 years, adenomas are the only tumors that can be detected before malignant transformation, and the detection of calprotectin has extremely important significance. The fecal calprotectin is very stable in feces, can accurately distinguish intestinal organic diseases and functional diseases by detection, and has higher accuracy in the aspect of identifying IBD and colorectal cancer. Compared with a colonoscope, the system has the advantages of simplicity, convenience, economy, no wound and the like, can avoid the pain of colonoscopy to a certain extent, and makes up the defect that a patient cannot be rechecked at any time. Compared with fecal occult blood, fecal calprotectin can be quantitatively detected, early stage non-bleeding focus can be found, and the result is not affected by the whole body condition, dietary components, common medicines and nutrition supporting treatment. Has important guiding significance for monitoring the condition of the diagnosed cases, evaluating the curative effect of the medicine, and the like.
However, the existing gastrointestinal tract diagnostic apparatus cannot work continuously, needs to be cleaned and reused after one-time measurement, has low detection efficiency, is inconvenient to clean and affects the diagnostic precision.
Therefore, it is necessary to develop a diagnostic apparatus for early stage gastrointestinal tumor to solve the above problems.
