Biopsy sampling and collecting device for clinical medicine

Abstract

The invention discloses a biopsy sampling and collecting device for clinical medicine. The biopsy sampling and collecting device comprises a sampling portion and an operating handle, wherein the sampling portion comprises a puncture needle and a needle tube, the top end of the puncture needle is provided with a tip end, the surface of the puncture needle is provided with a sampling groove, the sampling groove is provided with a sampling knife, the puncture needle is connected in the needle tube in a sliding manner, the operating handle is provided with a connector, one end of the sampling portion extends into the operating handle to be connected with a moving seat, and the operating handle is provided with a long hole. An operating block is arranged on the long hole, and a sliding key isarranged on the operating block. Due to the arrangement of the needle tube and the puncture needle, the puncture needle can accurately reach the sampling point, the resistance of the beak-shaped tip of the puncture needle is smaller, the puncture needle is convenient to penetrate deeply, the key is turned to control the rapid extension and retraction of the puncture needle, the sampling knife cutsand samples a sample to the sampling groove, and the sample is retracted into the needle tube, so that the sample is prevented from being tilted out in the process of extracting the needle tube, virus cells are not diffused, and the puncture needle is safer. Due to the arrangement of the sampling groove, the taken sample can be taken out more conveniently.

Description

technical field [0001] The invention relates to the technical field of medical sampling, in particular to a biopsy sampling collection device for clinical medicine. Background technique [0002] Biopsy (biopsy) referred to as "biopsy", also known as surgical pathological examination, referred to as "external examination"; refers to the need for diagnosis and treatment, to remove diseased tissue from the patient's body, such as cutting, forceps or puncture, for pathological examination. Check the technique. It is the most important part of diagnostic pathology. It can make a clear histopathological diagnosis for the vast majority of cases submitted for inspection, and it is used as the final clinical diagnosis. [0003] However, most of the existing sampling devices use a syringe-style structure to suck the sample under negative pressure. Because the needle tube used for sampling is relatively small, the sample sucked is less, and it is easy to be blocked. The hollow needle ...

Problems solved by technology

[0003] However, most of the existing sampling devices use a syringe-style structure to suck the sample under negative pressure. Because the needle tube used for sampling is relatively small, the sample sucked is less, and it is easy to be blocked. The hollow needle tube has low strength and is easy to work. The bending causes inaccurate sampling, and the collected samples are not easy to take out
