Abstract: A surgical technique in which a tumescent solution of local anaesthetic and a vasoconstrictor in injected into the site via a cannula. Using the same cannula, the surgeon aspirates fat and tissue from the site, depositing the aspirated fat and tissue into the reservoir/bottle from which the tumescent solution was first withdrawn. Preferably, both the injection and the aspiration is accomplished with the assist of a single peristaltic pump. By reversing the headstock of the peristaltic pump, and modulating the speed of rotation, the peristaltic pump both injects and aspirates the site. The aspirated fat and tissue is kept in a closed cycle so that contamination is minimized and exposure to the air by the fat is prevented; thereby permitting the aspirated fat to be used elsewhere for body contouring.

Abstract: An improved medical tool which combines tumescent anesthetic solution with lipoplastic. Using a peristaltic pump and a cannula, the surgeon directs the tumescent solution into the area of concern. The tumescent solution provides both a local anesthetic as well as a vasoconstrictor. The solution eliminates the need for a general anesthetic, thus eliminating problems associated therewith, and the solution causes the blood vessels to constrict, reducing the amount of blood loss during the procedure. Once the solution has had an opportunity to perform its function, the surgeon reverses the direction of the peristaltic pump and removes the fat and tissue through the same cannula used for the tumescent portion of the operation. Since the suction process is performed by the peristaltic pump (as opposed to manually by the surgeon), the cannula is reduced in size to a highly versatile and tactile instrument providing highly improved results.
