Cannula with retractable spring-loaded arced tip

A cannula arrangement comprising:

• a handle defined between a handle distal end and a handle proximal end;
• a rigid outer tube extending to an outlet port from the handle distal end of the handle, wherein no portion of the rigid outer tube is covered by another tube of the cannula arrangement from the handle distal end to the outlet port;
• an inner tube having only one passageway extending from a proximal tube end to a distal tube end;
• a suction-irrigation tip attached to the distal tube end, wherein the suction-irrigation tip comprises a plurality of perforations that maintain continuous fluid communication between an external environment and a suction-irrigation port at the proximal tube end which is configured to connect to a hose;
• the inner tube comprising a flexible tube segment interposed between the suction-irrigation tip and a rigid inner tube segment, the rigid inner tube segment extending from the flexible tube segment to the proximal tube end, wherein the inner tube is configured to contain only material consisting of air, irrigation fluid and/or bodily fluid when in operation;
• the inner tube slidingly engaged in the rigid outer tube, wherein when the inner tube is fully retracted in the rigid outer tube with the suction-irrigation tip abutting the outlet port, the flexible tube segment is entirely in the rigid outer tube and a majority of the rigid inner tube segment is in the rigid outer tube.
