Description

Technical Field

[0001] The utility model belongs to the technical field of tissue picking tools for biological detection, and more specifically, particularly relates to a tissue picking tool. Background Art

[0002] Biological genetic testing is a technology that detects DNA through blood, other body fluids, or cells. It is a method of taking peripheral venous blood or other tissue cells of the subject, amplifying their genetic information, and then using specific equipment to detect the DNA molecular information in the cells of the subject to analyze the gene types and gene defects it contains and whether its expression function is normal, thereby understanding the genetic information of the organism. When collecting biological tissues, specific parts (such as tissues with narrow sampling space) need to be sampled.

[0003] Based on the above, when sampling, the currently commonly used tissue samplers need the sampling personnel to rely on experience to place the tool at the tissue sampling location, and then need to repeatedly adjust the sampling tool. Most sampling picking tools are prone to damage to surrounding tissues during adjustment. At the same time, additional tools are required to peel off the sample after picking. At the same time, when the picking tool is idle, the picking component does not have a protective structure, and the picking component is prone to unnecessary wear. Utility Model Content
