Abstract
A surgical access device, such as in the form of a Veress needle or trocar/obturator, for use in providing access to a patient in a surgical setting is disclosed. The surgical access device incorporates one or more sensors to provide real-time data usable to evaluate an insertion position of the surgical access device and provide feedback to a live user or robotic insertion device. Additionally, a system and method for adjusting the flow of insufflation gas based on the real-time data and a sensed pressure at the surgical access device is described.

-10. (canceled)
A method for use in performing a laparoscopic surgical operation, the method comprising:
- inserting a laparoscopic access device, the laparoscopic device having an insertion tube comprising an outer sheath slidably connected to an inner sheath, into an abdominal wall of a patient;
- while inserting the laparoscopic access device:
- automatically monitoring a displacement of the outer sheath relative to the inner sheath;
- automatically monitoring, with at least one inertial measurement sensor embedded into the laparoscopic access device, an orientation and an acceleration of the laparoscopic access device;
- transmitting to a controller in communication with the laparoscopic access device, in real-time, data relating to the monitored displacement, orientation and acceleration;
- and
- providing feedback to a user of the laparoscopic access device regarding positioning of the laparoscopic access device based on the transmitted data.
