ABSTRACT:
An endoscopic surgery cannula insertable into a surgical site in a patient for coaxially slideably receiving an endoscopic surgical tool. The cannula comprises a distal portion insertable into the surgical site. The cannula further comprises a proximal portion accessible to surgical personnel for receiving an endoscopic surgical tool and having a passage through which the distal portion of the surgical tool can be brought into the surgical site. The cannula proximal portion comprises a lock mechanism transversely slidable for interfering with axial movement with the tool therein and elastomeric loop structure stretchable for resiliently urging the lock mechanism transversely on the cannula to a lock position retaining the surgical tool in the cannula and which may be resiliently overcome to permit removal of the tool from the cannula.
