Abstract
A biopsy apparatus includes a biopsy needle, a sample manifold, and a sample container. The sample manifold is coupled to the biopsy needle. The sample manifold has a receptacle and an insertion axis. The sample receptacle has an interior side wall and a mounting pin that projects inwardly from the interior side wall toward the insertion axis. The sample container is configured for insertion into the receptacle. The sample container includes a cap portion, a basket portion, and a hinge, wherein the cap portion is joined to the basket portion by the hinge.
Claims21
A biopsy apparatus, comprising:
- a biopsy needle;
- a sample manifold coupled to the biopsy needle, the sample manifold having a receptacle and an insertion axis, the sample receptacle having an interior side wall and a mounting pin that projects inwardly from the interior side wall toward the insertion axis;
- and
- a sample container configured for insertion into the receptacle, wherein the sample container includes a cap portion, a basket portion, and a hinge, wherein the cap portion is joined to the basket portion by the hinge.
A coaxial introducer cannula for use with a biopsy apparatus, the biopsy apparatus having a front plate having a catch, and a biopsy needle that extends from the front plate on a longitudinal axis, the coaxial introducer cannula comprising:
- a coaxial cannula sized to be coaxially and slidably received over the biopsy needle;
- and
- a hub, the hub being fixedly attached to a proximal portion of the coaxial cannula, the hub having a hub body, a latching lever, and a latch, the latch configured to rotatably engage the catch, and wherein the latching lever extends radially from the hub body relative to the longitudinal axis, the latching lever being longer than a height of the front plate so that the latching lever can be reached and rotationally operated to rotate the hub relative to the front plate of the biopsy apparatus, thereby facilitating single-handed rotation of the coaxial introducer cannula relative to the front plate, so as to effect a respective engagement or disengagement of the latch of the coaxial introducer cannula with the catch of the front plate.
