SENSING DEVICE AND METHOD FOR TRACKING A NEEDLE BY MEANS OF ULTRASOUND AND A FURTHER SENSOR SIMULTANEOUSLY

摘要

The invention relates to a sensing device (1) for providing guidance for a medical device (5), in particular a needle, comprising - a probe housing (2) and - an ultrasound sensor (3), which is at least partly surrounded by the probe housing (2), for acquiring target information concerning a medical target (6) by means of ultrasound (7), - wherein the sensing device (1) is configured to provide the target information for providing guidance in positioning the medical device (5), in particular the needle, relative to the medical target (6). To improve the tracking of the medical device (5), in particular the needle, it is envisaged that - a sensor unit (4) which is directly arranged at the probe housing (2), wherein the sensor unit (4) is configured to acquire position data concerning a position of the medical device (5), in particular the needle, by means of an acquisition principle, which is different from the ultrasound sensor (3).
