The aim of this study was to measure the sharpness of tip and cannula of needle of Automated Gun Biopsy, to find out the difference. Accuracy was measured using AIKOH Electric Push-Pull Standard Model MV-600N2, and 3mm thick silicon was used to reproduce the toughness of human skin. The needle part of the four automatic biopsy guns used in this hospital was cut and tested. The automatic biopsy guns used in the experiment are all 18G, and the cannula part which role of the tissue by covering the appearance of obturator needle and obturator needle with true cut method. is integrated. The average value was obtained from experiments which were performed on each needle 5 times in total, the unit was designated N. As a result, the sharpness of tip was more than 3N, and the degree of sharpness was higher in order of A → C → D → B. Cannula had degree of sharpness in the order of D → C → A → B and showed sharpness close to 1N. C and B products had the same order of sharpness of tip and cannula part, and A and D showed different sharpness. In conclusion, this study measured only the sharpness of four automatic biopsy guns, but it is necessary to study the operation method of the main body, safety, convenience of operation and to experiment various automatic biopsy guns of various manufacturers.
