Abstract: An ultrasonic surgical liposuction apparatus comprises a piezoelectric crystal transducer assembly is connectable to an interchangeable operative probe and tip. The probe can be hollow, if aspiration of the fatty tissue is desired, or it can be solid. The tip is largely formed of a plastic material, to prevent the propagation of the ultrasonic waves to the distal end of the apparatus. Prevention of propagation of the ultrasonic energy to the distal end prevents unwanted damage of the tissues by an excessively hot tip. The tip can be removable or permanently affixed by a weld. The tip can have a metal jacket covering the lateral surfaces of the plastic tip body, to assist penetration of the fatty tissue, or the tip can be entirely made of plastic. The tip can also have an opening or series of openings for aspiration of the fatty tissue.

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the site, depositing the aspirated fat and tissue into the reservoir/bottle from which the tumescent solution was first withdrawn.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: A cannula for an eye-surgery instrument, employed to shatter the lens of the eye by high-frequency oscillation and to suction out the fragments. It accommodates a suction channel with a section that is wider toward the tip of the cannula. The wider section (20) comprises at least two straight bores (8, 9, & 10), one wider than another, extending coaxial with the suction channel (7) into the cannula (1) from its tip (5). Fragments of the shattered lens accumulate in the bores in accordance with size, where they can be further fragmented by ultrasound.

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.

A flexible backing plate is attached to the absorbent portion. Channels formed a long the backing plate direct the vacuum evenly across the absorbent portion of the device such that fluid is drawn evenly from the absorbent portion. Suction tubing connects the absorbent portion to the suction source. The absorbent portion and attached backing plate can be folded to fit into small areas.

Abstract: A medico-surgical suction system has a container with an outlet connected to a vacuum pump and an inlet connected to a suction catheter via a dual-lumen tube assembly one end of which is connected to the container and the other end of which is has a suction control and a coupling for the catheter. A valve located in the outlet of the container is connected to the suction control via a minor lumen of the tube. A side lumen enables the vacuum pump to apply reduced pressure to one end of the valve which holds the valve off against the action of a spring. Actuation of the suction control allows air to flow to the valve via the minor lumen so that the effect of the reduced pressure is overcome and the spring opens the valve.

Abstract: Recovery of blood from a wound site (12) during a surgical procedure is accomplished with low blood trauma that enables collection of increased amounts of blood having relatively little structural damage for return to the surgical patient.
