Abstract

The lipectomy device includes a generally hollow tubular housing to the open front end of which are releasably sealingly connected an elongated hollow tubular suction conduit, with a rounded closed front end bearing at least one opening, and a cutting blade with the shaft and cutting tip thereof wholly disposed in the conduit and spaced inwardly therefrom. The cutting blade is releasably connected to an electrical motor in the housing for rotation of the blade, and a suction line also runs into the front end of the housing to remove severed tissue sucked through the blade and/or conduit. The device may include an electrocoagulation component which includes the blade tip in the form of electrically resistive metal, and an electrical circuit between a housing switch, the blade tip and an external electrical power source. The device is compact, portable and efficient in removing lipoidal tissue by suction, with excision thereof by the blade tip as it rotates in the conduit and also providing electrocoagulation, as needed, by the blade tip of small blood vessels to avoid hematomas.

Claims9

Dependent claims

An improved lipectomy device, said device comprising, in combination:

(a) an elongated generally tubular suction conduit having a central passageway extending the length thereof, a rounded generally closed front end with at least one opening therein extending into said passageway, and a rear coupler;
(b) an elongated cutting blade releasably secured to said conduit in said passageway, and a front cutting tip adjacent said conduit front end and wholly within said passageway, said blade including a rear fitting;
(c) a tubular housing having an open front end communicating with a central cavity therein, a suction line connected to said central cavity in said front end and extending exterior of said housing for connection with a suction source, coupling means releasably connected to said rear coupler and said rear fitting for releasably sealingly securing said blade and said conduit in said housing front end to close the same, with said blade shaft and tip disposed in said conduit, and drive means in said housing releasably connected to said blade for rotation thereof in said conduit;
and
(d) electrocoagulation means connected to said blade tip, the blade tip being electrically conductive.
