Abstract | A guidance system for assisting with the insertion of a needle into a patient body is disclosed. The guidance system utilizes ultrasound imaging or other suitable imaging technology. In one embodiment, the guidance system comprises an imaging device including a probe for producing an image of an internal body portion target, such as a vessel. One or more sensors are included with the probe. The sensors sense a detectable characteristic related to the needle, such as a magnetic field of a magnet included with the needle. The system includes a processor that uses data relating to the sensed characteristic to determine a 3-D position of the needle. The system includes a display for depicting the position of the needle. A needle assembly including a hub, cannula, and magnetic element is also disclosed, wherein the cannula is substantially non-magnetic so as to not distort the magnetic field of the magnetic element.
披露了一种用于帮助将针头插入患者体内的引导系统。该引导系统利用超声成像或其他合适的成像技术。在一个实施方案中,该引导系统包括成像设备,该成像设备包括用于产生诸如血管等体内部分目标的图像的探针。该探针 |
