Kraftunterstütztes Fettabsaugehandgerät

摘要

A power assisted liposuction/lipoinjection handpiece includes a handle (12) which provides power to reciprocate a cannula (10) back and forth during surgery The cannula (10) can be connected to the handle (12) by a connector (24) that is affixed to, integrally formed with, or selectively joinable to a reciprocating member (14). Benefits in sterilization, distribution and surgical use can be realized when the cannula (10) and connector (24) are joined together, such that the surgeon merely needs to remove the cannula (10) from the package and connect it to a reciprocating member of a powered handle (12). The handle (12) may be configured such that the reciprocating member (14) is selectively detachable; thereby, allowing the handle (12) to be used for additional surgical procedures such as sawing or drilling. A vacuum hose (26) is connected to the cannula (10) such that vacuum pressure can be exerted through the cannula (10) for aspirating severed fat tissue. Preferably, the connector (24) radially offsets the cannula (10) from the reciprocating member (14) to a position which is axially in alignment with the vacuum hose (26); thereby avoiding bend regions and enhancing suction.
