摘要：In this paper, a new model of bionic biopsy needle was proposed, primary cutting angle of the needle was defined and main cutting angles calculation methods and general calculation formulas were derived. In addition, the processing method and processing platform were introduced. Multiple times of puncture sampling experiments were performed using the beak needles with different azimuth angles, conventional plane needle and lancet needle, which use pork liver as the experimental material, The experiment results showed that the new type of biopsy needle has better sampling performance than that of the conventional plane needle and Lancet needle.
