  • Biopsy apparatus having integrated thumbwheel mechanism for manual rotation of biopsy cannula
    Patent number: 10575833
    Abstract: A biopsy apparatus includes a housing, a biopsy cannula mounted to the housing, and a cannula rotation mechanism mounted to the housing. The cannula rotation mechanism has a thumbwheel, a first gear, and a second gear. The thumbwheel is configured to rotate about a rotational axis, with the rotational axis being perpendicular to the longitudinal axis of the biopsy cannula. The first gear is mounted in fixed attachment to the thumbwheel. The second gear is mounted in fixed attachment to the biopsy cannula. The first gear is in mesh with the second gear such that the first gear is directly drivably engaged with the second gear to rotate the biopsy cannula about the longitudinal axis when the thumbwheel is rotated.

  • Biopsy apparatus having integrated thumbwheel mechanism for manual rotation of biopsy cannula
    Patent number: 9655599
    Abstract: A biopsy apparatus includes a driver assembly and biopsy probe mechanism drivably coupled to the driver assembly. The biopsy probe mechanism includes a biopsy cannula having a cylindrical side wall that defines a lumen and has a side port located near a distal end that extends through the side wall to the lumen. A thumbwheel mechanism includes a thumbwheel mounted to the driver assembly to rotate about a first rotational axis, the first rotational axis being substantially perpendicular to the longitudinal axis. A first gear is mounted to the thumbwheel for coaxial rotation with the thumbwheel about the first rotational axis. A second gear is mounted to the biopsy cannula for coaxial rotation with the biopsy cannula about the longitudinal axis, the second gear being located to be drivably engaged by the first gear. The housing is grasped and the thumbwheel rotated with a single hand.
