ABSTRACT:
A safety penetrating instrument for introducing a portal sleeve into an anatomical cavity particularly useful in least invasive surgery includes a safety probe having a distal end configuration cooperating with the sharp distal tip of a penetrating member to protect the tip in an extended position and to expose the tip in a retracted position. The configuration of the distal ends of the penetrating member and the safety probe in the retracted position form a solid, continuous surface tissue penetrating tip for the safety penetrating instrument. The safety probe and penetrating member can be removed from the portal sleeve as a unit or the safety probe can be removed while leaving the penetrating member in place for use in further procedures. The safety probe can carry interchangeable protective bodies on the distal end thereof, the bodies being made of flexible, pliable and preferably resilient materials.
