Arthroscopic nozzle for protecting tissue during arthroscopic surgery, has external compression system for compressing tissue wall crossed between system and unfolded dynamic distal anchoring, when lid is screwed by external screw

摘要

The nozzle has a dynamic system of distal anchoring, which prevents a detaching of the nozzle from a passage when the system is opened. The anchoring frees the nozzle to enter and come out from tissues, when the system folds up. An external compression system compresses a tissue wall crossed between the compressing system and the unfolded dynamic distal anchoring, when a lid of the system is screwed by an external screw.
