Abstract

The invention relates to the technical field of biopsy sampling, in particular to a biopsy sampling device for a medical oncology clinic. The device comprises a needle tube, a mounting block and a pull rod, wherein the right end of the needle tube is fixedly provided with the left side of the mounting block, the left end of the needle tube is fixedly provided with a puncture head for puncturing tissue, a cutting hole with an upward opening is formed in the side, close to the puncture head, of the needle tube, a transition cavity is formed in the left side in the mounting block, a connecting block is arranged in the transition cavity, the pull rod extending rightwards to the outside of the mounting block is arranged on the right side of the connecting block, a holding block is arranged at the end of the pull rod, and a spring is arranged between the holding block and the mounting block. According to the device, through the cutting hole, a cutting blade and an inclined groove, the tissueat the cutting hole can be sampled multiple times in one puncture process, so that the sampling operation difficulty is reduced, the sampling time is shortened, and the pain of a patient is reduced;and meanwhile, it is ensured that a plurality of pieces of sample tissue obtained through continuous sampling are prevented from slipping off or being lost, and the continuous sampling effect is ensured.

Description

technical field [0001] The invention relates to the technical field of biopsy sampling, in particular to a biopsy sampling device for clinical oncology. Background technique [0002] Tumor is a disease that seriously endangers human health and life. In recent years, the incidence rate has gradually increased, and the age of onset has gradually decreased. Early detection, correct diagnosis, and timely treatment have an important impact on prognosis. With the continuous improvement of examination methods and methods, the correct rate of diagnosis has gradually increased, but there are still a large part of tumors that do not have typical imaging features, making diagnosis more difficult. A correct diagnosis requires a combination of clinical, imaging, and pathological factors. Among them, pathological diagnosis plays a key role in the selection of treatment options. Needle biopsy is the main way to obtain pathological diagnosis. [0003] Among them, the biopsy puncture samp...
