摘要：
A safety trocar assembly incorporating an airbag is provided to prevent overpenetration of the safety trocar assembly through an abdominal wall and into a body cavity. The safety trocar assembly includes an airbag cannula having an expandable airbag proximal of the distal end of the cannula. A sensing device is located at a distal end of the cannula for detecting changes in conditions at the distal end of the cannula. A trigger mechanism is provided on the cannula and operates to inflate the airbag in response to a change in condition detected by the sensing device.
