Title: SURGICAL TOOL WITH FLEX CIRCUIT ULTRASOUND SENSOR
Abstract:
A medical instrument includes a printed ultrasound sensor, a surface, at least one non-conductive material, and at least one pair of contacts. The ultrasound sensor includes an array of ultrasound transducers printed on a non-conductive surface of the medical instrument. The medical instrument contains multiple conductive and nonconductive layers. The at least one pair of contacts are electrically coupled to the ultrasound sensor and operably coupled to the conductive layer, the conductive layer coupled to a measurement device, which converts electrical signals from the ultrasound sensor into images displayed on a display unit. The location of the medical instrument can be visualized in real time on the display unit.
