Biopsy device handle

1. A biopsy device handle comprising:

an elongated housing, the length of the housing defining a longitudinal axis;

a carriage disposed within the housing and having a flexible abutment;

a catch overlapping at least a portion of the abutment in a longitudinal direction;

a first trigger disposed in the housing and movable longitudinally within the housing and contacting a portion of the flexible abutment wherein longitudinal movement of the first trigger causes a first contact force to be applied to the abutment;

a second trigger disposed in the housing and movable transversely within the housing and contacting a portion of the flexible abutment wherein transverse movement of the second trigger causes a second contact force to be applied to the abutment;

wherein the abutment is configured to flex away from the catch when forced by either the first or second contact force, such that the catch does not overlap a portion of the abutment.

2. The biopsy device handle of claim 1 , wherein the carriage is configured to slide longitudinally within the housing and the catch is disposed distally of the abutment when the catch is overlapping the abutment.

3. The biopsy device handle of claim 2 , wherein the carriage is biased in a distal direction by a biasing element.

4. The biopsy device handle of claim 1 , wherein the first trigger is a button disposed in an end of the housing and configured to depress into the housing.

5. The biopsy device handle of claim 1 , wherein the second trigger is a button disposed in a side of the housing and configured to depress into the housing.

6. The biopsy device handle of claim 1 , wherein the flexible abutment includes an inclined face at an angle to the longitudinal axis, the angled face deflecting at least partially in a transverse direction when a longitudinal force is applied to the angled face.

7. The biopsy device handle of claim 6 , wherein the inclined face is on a post extending from the abutment.

8. The biopsy device of claim 1 , wherein the abutment is generally T-shaped.

9. The biopsy device handle of claim 3 , wherein the biasing element forces the carriage in a distal direction when the abutment is flexed away from the catch.

10. The biopsy device handle of claim 1 , further including a channel having first and second opposing walls, wherein the catch extends inwardly from the first wall of the channel.

11. The biopsy device handle of claim 10 , wherein the abutment is flexed between the catch and the second wall of the channel.

12. The device of claim 11 , further comprising a switch on a side of the housing, the switch having an internal protrusion extending transversely within the housing and configured to slide longitudinally between a first position and a second position;

wherein the internal protrusion is disposed between an interior wall of the housing and the abutment in the first position, and the internal protrusion is misaligned with the abutment in the second position.

13. The biopsy device of claim 1 , further comprising a first biasing element disposed between a proximal end of the housing and the carriage and configured to bias the carriage in a distal direction, a lever operatively linked to the catch, a latch configured to slide longitudinally to releasably engage the lever in a proximal direction and a second biasing element disposed distally of the latch and configured to bias the latch in a proximal direction; wherein the lever is configured to move the catch distally of the abutment when opened and move the catch in a proximal direction when closed; and wherein the catch is configured to engage the abutment when the catch is moved in the proximal direction such that the carriage is forced against the first biasing element; and wherein the latch further includes a blocker configured to engage a proximal face of the carriage such that the latch is prevented from moving distally when the carriage is moved to a proximal position.
