Testing method for left wheel type mammary gland rotary cutting biopsy gun

The invention provides a testing method for a left wheel type mammary gland rotary cutting biopsy gun. The testing method comprises the following steps: (1) testing the rigidity and puncture force of an outer needle; (2) testing the inner needle insertion continuity; (3) ultrasonic detectability testing of the outer needle and the inner needle; (4) testing the sampling amount of the inner needle; (5) testing the continuity of bin changing movement of the sample storage bin; and (6) testing the motion continuity of the firing mechanism. By adopting the complete testing method, various characteristics and movement continuity of the left wheel type mammary gland rotary cutting biopsy gun are ensured, so that the movement precision of a rotary cutting system is ensured, and the use is safer and more reliable. 本发明提供了一种用于左轮式乳腺旋切活检枪的测试方法，包括：(1)外针刚度及穿刺力测试；(2)内针进针连续性测试；(3)外针、内针超声可探测性测试；(4)内针取样量测试；(5)储样仓换仓运动连续性测试；(6)击发机构运动连续性测试。采取该完整的测试方法，使得左轮式乳腺旋切活检枪的各方面特性以及运动连续性得以保证，从而使旋切系统的运动精度得以保证，使用更加安全可靠。
