    摘要: A surgical instrument for the presence and/or location of a foreign body is disclosed. The surgical instrument is hand-held. In some embodiments, the surgical instrument includes transducers adapted for emitting and/or receiving signals. In such embodiments, the surgical instrument utilizes pulse-echo measurements to determine characteristics and/or location of the foreign body. In other embodiments, the surgical instrument includes a measurement circuit for detecting the presence and/or location of a foreign body by a change in the characteristics of the measurement circuit. The surgical instrument may be utilized to determine such things as the size of a foreign body, the orientation of a foreign body with respect to patient anatomy and/or another foreign body, and whether the foreign body has been completely removed.
