The invention discloses a liver puncture biopsy device for drug anti-liver fibrosis research. , the rotating shaft is fixedly connected with the output end of the external power source, the arc contour of the rotating shaft is fixedly connected with a first incomplete gear, and the arc contour of the rotating rod is fixedly connected with a second incomplete gear that intermittently meshes with the first incomplete gear. A complete gear, a chute is provided on the bearing plate, and a rack is slidably connected through the chute, and the rack is intermittently meshed with the first incomplete gear and the second incomplete gear. Sliced cutting mechanism. Through the cooperation of the overall structure, the present invention achieves the effect of not requiring a doctor's operation, reducing the doctor's workload and causing no further harm to the patient, and greatly reducing the operation difficulty of the doctor by setting the cutting mechanism. |
