Abstract:
1. A system for performing arthroscopic surgery comprising: an arthroscopic instrument; an extravasation minimization device disposed about an outer diameter of the arthroscopic instrument, said extravasation minimization device comprising a helical structure having a drainage lumen disposed therein, said helical structure characterized by a distal end, a proximal end and an inner diameter sized and dimensioned to be removably disposed over the arthroscopic instrument, and a plurality of drainage apertures disposed on the outer surface of the helical structure in fluid communication with the drainage lumen; and a vacuum source in fluid communication with the drainage lumen; wherein said helical structure is structured to allow fluid to flow through the drainage lumen, from a surgical site to a vacuum source, when said extravasation minimization device is disposed within an arthroscopic workspace; and wherein the arthroscopic instrument comprises a threaded surface working cannula wherein the helical structure is disposed between the lead of the screw threads.
