Abstract
A biopsy device may include a first jaw having a first distal tip configured to pierce tissue, and a second jaw movable relative to the first jaw between a closed configuration where the first jaw and the second jaw are axially aligned, and an open configuration where the first jaw and the second jaw are offset from one another, the second jaw having a second distal tip proximal to the first distal tip in the closed configuration.
Claims20
A biopsy device, comprising:
- a first jaw having a first distal tip and a pair of radially-outward facing surfaces forming a radially-outward facing sharp edge in between the pair of radially-outward facing surfaces, wherein the first distal tip is configured to pierce tissue, and the radially-outward facing sharp edge is configured to sever the pierced tissue;
- and
- a second jaw movable relative to the first jaw between a closed configuration where the first jaw and the second jaw are axially aligned, and an open configuration where the first jaw and the second jaw are offset from one another, the second jaw having a second distal tip proximal to the first distal tip in the closed configuration, the second distal tip is configured to sever the pierced tissue when the second jaw moves relative to the first jaw;
- wherein a collective width of the first jaw and the second jaw when in the closed configuration is equal to a width of the first jaw when in the open configuration.
A biopsy device, comprising:
- a first jaw having a first distal tip and a plurality of radially-outward facing surfaces terminating at the first distal tip, wherein the plurality of radially-outward facing surfaces form at least one radially-outward facing sharp edge at an intersection between each of the plurality of radially-outward facing surfaces, wherein the first distal tip is configured to pierce tissue, and the radially-outward facing sharp edge is configured to sever the tissue pierced by the first distal tip;
- and
- a second jaw having a second distal tip proximal to the first distal tip, wherein the second jaw is movable relative to the first jaw between a closed configuration and an open configuration, the second distal tip is configured to sever the tissue pierced by the first distal tip.
A biopsy device, comprising:
- a first jaw having:
- a first distally-directed tip configured to pierce tissue;
- a first proximal end including a protrusion configured to grasp tissue, wherein the first distally-directed tip extends transversely relative to the protrusion;
- and
- a first center portion positioned between the first distally-directed tip and the first proximal end;
- a second jaw having:
- a second distally-directed tip configured to contact the first center portion when the first jaw and the second jaw are in a closed configuration;
- and
- a second proximal end including an opening that extends through an outer surface of the second jaw, the protrusion being received through the opening to engage tissue positioned between the first jaw and the second jaw when the first jaw and the second jaw are in the closed configuration.
