  • Patent number: 11259862
    Abstract: A coaxially-driven tissue aspiration instrument having a hand-supportable housing with a stationary tubing connector provided at the rear of the housing and receiving a length of flexible tubing connected to a vacuum source. A twin cannula assembly is coupled to a an electromagnetic cannula drive mechanism disposed within a guide tube structure mounted in the hand-supportable housing and powered by electrical power signals so as to periodically exert forces on the a front-loaded cannula base device slidably supported within the guide tube structure, and to which the inner cannula is releasably connected. The coaxially exerted forces cause the front-loaded cannula base device, and thus inner cannula, to reciprocate within the guide tube structure, while tissue is being aspirated along the inner cannula lumen, through the reciprocating front-loaded cannula base device, and through the stationary tubing connector, and along the flexible tubing towards the vacuum source.
