Abstract
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.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
145 words
A surgical assembly comprising: a) a lipoplastic cannula having an enclosed channel extending therein, a handle portion proximate to a first end thereof, and further having vent openings proximate to an end opposite said handle portion and communicating with said enclosed channel, said handle portion being suitable for use with a single hand of a surgeon and being less than twenty millimeters in diameter; b) a flexible bag reservoir containing a medicated liquid being a local anesthetic and a vasoconstrictor; c) a flexible clear tubing communicating said channel in said cannula with said flexible bag reservoir; and, d) a reversible pump means interposed between said cannula and said flexible bag reservoir for selectively communicating, via said flexible tubing, said medicated liquid from said flexible bag reservoir to said cannula, and for communicating body materials and liquids from a patient via said cannula to said reservoir.
Claim 2
Dependent Claim
