Abstract
Abstract A trocar penetration depth indicator has a first, inner housing including a first threaded section and longitudinally extending gripping fingers, and a second, outer housing including a camming surface and a second threaded section to engage the first threaded section. The first and second housings slidably mount onto a trocar tube and can be secured relative to the guide tube by rotatably tightening the housings to cause the gripping fingers to firmly grip the trocar tube. Depth penetration indicia is provided on the guide tube surface and sufficient guide tube grasping force is obtained to prevent the depth indicator from being dislodged during trocar insertion. A guide tube positioning device is provided to engage the penetration depth indicator and to secure the guide tube relative to the surrounding skin of the patient in order to prevent inadvertent withdrawal or further insertion of the trocar.
