Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a puncture sampler for an oncology department.
Background
The tumor is a new organism formed by that certain cells of local tissues lose normal regulation and control on the growth of the local tissues at the gene level under the action of various carcinogenic factors, so that the local tissues are clonally abnormally proliferated. It is generally accepted that tumor cells are monoclonal, i.e., all tumor cells in a tumor are progeny of a mutated cell. Tumors are generally classified into two broad categories, benign and malignant. Benign tumors are commonly referred to as "tumors", malignant tumors from epithelial tissue as "carcinomas", and from mesenchymal tissue as "sarcomas". Certain such malignant tumors may also be referred to as "tumors" or "diseases," such as malignant lymphoma, seminoma, leukemia, hodgkin's disease, and the like. All malignant tumors are customarily known as cancers or carcinomas.
In the case of confirming a tumor or a suspected tumor, pathological analysis is generally required, and a common means is to sample the suspected tumor and then to perform pathological detection on the sampled sample, while the conventional pathological sampling method includes the steps of inserting a positioning needle into the tumor, separating a syringe from the positioning needle, inserting the sampling needle into the positioning needle, tightly connecting the sampling needle with the positioning needle, and pressing the end part to perform sampling, so that the sampling step is a separated intermittent operation, the continuity is not strong, the operation time is relatively long, and the number of the sampled samples is limited and the position of the sampled sample has specificity.
