Biopsy instrument driver apparatus
First Claim
1. A driver apparatus for use with a biopsy instrument which includes a plurality of relatively movable elongated members, the driver apparatus comprising:
- a housing;
an insertion mechanism including a carriage movably associated with the housing and being adapted to support the biopsy instrument to affect longitudinal movement of at least a portion of the biopsy instrument relative to the housing; and
a linear motion control mechanism adapted to move a tissue cutting element of the biopsy instrument from a first position to a second position relative to a tissue receiving portion of the biopsy instrument wherein the tissue cutting element cuts tissue extending into a tissue receiving portion of the biopsy instrument; and
a tissue retract mechanism which facilitates removal of a tissue specimen from the biopsy instrument without removing the entire biopsy instrument from a surgical site, the tissue retract mechanism including a retention member adapted to retain a portion of the biopsy instrument, the tissue retract mechanism further including a longitudinal guide member which slidably guides the retention member and is disposed relative to the housing in a manner to permit movement of the longitudinal side member relative to the housing.

Abstract
A driver apparatus is provided for use with a biopsy instrument, the driver apparatus including a housing and an insertion mechanism including a carriage movably associated with the housing and adapted to support the biopsy instrument to affect longitudinal movement of at least a portion of the biopsy instrument. A linear motion control mechanism is also included that is adapted to move a tissue cutting element of the biopsy instrument from a first position to a second position relative to a tissue receiving portion of the biopsy instrument. Further, a tissue retract mechanism is included which facilitates removal of a tissue specimen from the biopsy instrument without removing the entire biopsy instrument from a surgical site.

2. A driver apparatus for use with a biopsy instrument which includes a tissue receiving portion and a cutting element, the driver apparatus comprising:
-
a housing;
an insertion mechanism adapted to support a biopsy instrument thereon, the insertion mechanism including a carriage movably associated with the housing such that the carriage is movable from a retracted position to an advanced position to affect longitudinal movement of the biopsy instrument; and
a cutting element controller assembly operatively disposed on the housing, the controller assembly including;
a linear motion control mechanism adapted to move a tissue cutting element of the biopsy instrument from a first position to a second position relative to a tissue receiving portion of the biopsy instrument wherein the tissue cutting element cuts tissue extending into a tissue receiving portion of the biopsy instrument; and
a motor operatively associated with the cutting element when the biopsy instrument is mounted on the biopsy instrument driver apparatus, such that the motor facilitates movement of the cutting element relative to the tissue receiving portion; and
an enabling switch disposed relative to the linear motion control member and electrically connected to the motor such that movement of the linear motion control member from the second position to the first position, causes the switch to activate the motor. - View Dependent Claims (5, 6, 7, 8, 9)
