【摘要】 针对临床上乳腺穿刺手术中精确定位穿刺枪的需求,设计出一款能匹配于国产乳腺机的立体定位穿刺导向架,以帮助医生提高手术质量。该装置包括运动模块、位移测量模块及显示模块,可实现三个方向相互垂直的直线运动,能实时显示三方向的运动位移。实验结果表明,该装置能与国产乳腺机良好匹配,使用感觉良好,各个运动方向的定位精度和重复性均较好,通过观察显示值,操作者可以准确改变穿刺枪的空间位置。更多还原

【Abstract】 To meet the need of accurate positioning for biopsy gun in the breast biopsy operation, a new stereotactic biopsy guide device have been developed to adapt to the domestic mammary machine, which can help physician to carry out biopsy operation more accurately and effectively. The guide device has the motion model, measurement model and display model and can realize linear motion and display real-time displacement values in X, Y and Z direction. The experimental results showed that the guide device could be well fxed in the domestic mammary machine, and achieved good accuracy and repeatability in each direction. Depending on the displacement values, physician can change the space of biopsy gun accurately.更多还原
