摘要：
A surgical instrument system for use in a surgical procedure is disclosed. The surgical instrument system may include an instrument configured to puncture the tissue of a patient and detect when the instrument has entered a lumen of the patient's body. The surgical instrument system may include one or more capacitive sensors near a tip of a needle and electrical circuitry to monitor the capacitance of the capacitive sensors. The capacitance of the capacitive sensors may change as the needle is inserted into different tissue of lumens of the patient's body, allowing for the position of the needle to be determined based on analysis of the capacitance of the capacitive sensors.
