Description
Technical Field
The invention relates to the technical field of medical treatment, in particular to an improved tumor nursing sampling device.
Background
Tumor (tumor) refers to a new organism (neograwth) formed by local tissue cell proliferation of the body under the action of various tumorigenic factors, because the new organism is mostly in the form of space-occupying block-shaped protrusion, also called neoplasms (neoplasms). It has been found that tumor cells exhibit metabolic changes that differ from normal cells, while the tumor cells themselves can adapt to changes in the metabolic environment by switching between glycolysis and oxidative phosphorylation (OXPHOS).
According to the cellular characteristics of the new organism and the degree of harm to the organism, tumors are divided into two major categories, namely benign tumors and malignant tumors. Malignant tumors can be classified into carcinomas and sarcomas, and carcinomas refer to malignant tumors derived from epithelial tissues. Sarcoma refers to malignant tumor of mesenchymal tissue including fibrous connective tissue, fat, muscle, vessel, bone and cartilage tissue, such as carcinoma formed by large intestine mucosa epithelium, which is called large intestine mucosa epithelial cancer, and is called large intestine cancer for short. The skin epithelium is called skin epithelial cancer, skin cancer for short, and the like. Therefore, if a doctor says that a person suffers from cancer, it indicates that the patient is a malignant tumor; if a person suffers from gastric cancer, it means cancer formed by gastric mucosal epithelium of the patient, and if the patient suffers from gastric sarcoma, it indicates that the malignant tumor is not formed by mucosal epithelial cells, may be caused by malignant change of smooth muscle cells, or belongs to malignant lymphoma of the stomach. But he may also be said to suffer from cancer in general.
The hospital all receives tumour patient every day, need sample when carrying out tumour inspection to the patient and confirm pathology, the tradition can lead to the crooked tissue of injury of syringe needle because of the human factor at the in-process of taking a sample with the cylinder direct sampling, increase the misery for patient, and the tradition sample makes the cell sap flow out and lead to the sample difficulty owing to do not exert pressure around tumour tissue, need sample many times, increase medical staff's burden, traditional cylinder sampling method drawback is the too thick sample difficulty of syringe needle, the syringe needle blocks up easily too thin, be not convenient for use.
