Directional puncture sampling equipment for treating hepatopathy

The invention belongs to the technical field of medical instruments, and particularly relates to directional puncture sampling equipment for treating hepatopathy, the directional puncture sampling equipment comprises a needle outer tube and a needle inner tube, the puncture end of the needle outer tube is fixedly connected with a baffle plate, the baffle plate is formed by splicing a plurality of base plates, and the base plates are made of elastic steel sheets; the inner needle tube is slidably mounted on the inner side of the outer needle tube, and the problems that existing sampling equipment is low in improvement accuracy, complex in process and inconvenient to use are solved. By arranging the baffle plate, tissues outside a target region are prevented from entering, the sampling accuracy is ensured, the tissues outside the target region are prevented from influencing the success rate of biopsy, a tissue sample of the target region is prevented from falling out during pulling out, and the tissue sample of
