Abstract

The invention discloses a puncturing sampling device for medical oncology. The puncturing sampling device comprises a sampling needle drum, a clamping mechanism, a pushing-pulling shaft, a sampling mechanism and a secondary picking mechanism, wherein the clamping mechanism is arranged on the right side of an outer ring of the sampling needle drum, the pushing-pulling shaft is movably clamped in aninner cavity of the sampling needle drum, the secondary picking mechanism is arranged in the middle of the left side of the sampling needle drum, and the sampling mechanism is installed on the left side of the secondary picking mechanism; the clamping mechanism comprises a rotating ring, an extending piece and an arc clamping plate; the sampling mechanism comprises a conical block, a containing groove, a first cutoff ring, a center shaft and a strong spring, the left side of the first cutoff ring is fixedly connected with the an outer ring of the right side of the conical block, and the leftside of the center shaft is fixedly welded to the center of the inner wall of the containing groove. The end inserted into the human body of the puncturing sampling device for medical oncology is designed through a closed solid, during needle inserting, the pain feeling is reduced, and compared with a hollow needle, it can be avoided that redundant tissue is sampled during needle inserting throughthe puncturing sampling device.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a puncture sampler for medical oncology. Background technique [0002] Tumor refers to the new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors, because this new organism is mostly a space-occupying blocky protrusion, also called neoplasm, according to the cell characteristics of the new organism and the According to the degree of harmfulness of the body, tumors are divided into two categories: benign tumors and malignant tumors. Cancer is the general term for malignant tumors. , the number of patients with various diseases is increasing, and the number of cancer patients is particularly changing. With the current technology and medical level greatly improved, the cure rate of various diseases is also increasing. [0003] In the field of medical oncology, it is often necessary to perform biopsy on patients durin...
