Abstract

An integrated biopsy needle assembly for use with a conventional biopsy gun comprises a hollow cannula, a stylet, a cannula hub operatively fixed to the proximal end of the cannula, a stylet hub operatively fixed to the proximal end of the stylet, and a hub strap operably associated therewith. The cannula hub is operatively fixed to the hub strap, while the stylet hub is capable of movement relative to the hub strap. The hub strap includes a top member, at least one side wall and at least one bottom member, thereby forming an inner channel. The cannula and stylet hubs further include a base and a cap, with the cannula and stylet hub caps being maintained at all times within the inner channel of the hub strap.

Claims (27)

1. An integrated biopsy needle assembly comprising:

a cannula having a distal end and a proximal end, and a hollow cross-section therebetween;

a stylet having a distal end and a proximal end, the stylet being adapted for sliding movement within the cannula;

a cannula hub operatively fixed to the proximal end of the cannula;

a stylet hub operatively fixed to the proximal end of the stylet; and

a hub strap operably associated with the cannula hub and the stylet hub, the cannula and stylet sharing a common longitudinal axis, in which at least a portion of said stylet reciprocates telescopically within at least a portion of said cannula, wherein the cannula hub is restrainably fixed to the hub strap to preclude longitudinal movement of both the cannula and the cannula hub relative thereto and the stylet hub, and, in turn, the stylet, is configured to be longitudinally movable relative to the hub strap.

2. The biopsy needle assembly of claim 1 , wherein the hub strap comprises a top member, at least one side wall and at least one bottom member, thereby forming an inner channel.

3. The biopsy needle assembly of claim 2 , wherein the cannula hub and the stylet hub each comprise a base and a cap.

4. The biopsy needle assembly of claim 3 , wherein the cannula hub cap and the stylet hub cap are retained within the inner channel of the hub strap.

5. The biopsy needle assembly of claim 3 , wherein at least one of the cannula hub base and the stylet hub base has a width at least equal to the width of the hub strap.

6. The biopsy needle assembly of claim 2 , wherein the cannula hub further comprises at least one outward projection.

7. The biopsy needle assembly of claim 6 , wherein the hub strap further comprises at least one notch associated with one of the top member, the at least one side wall and the at least one bottom member.

8. The biopsy needle assembly of claim 7 , wherein the at least one outward projection is retained within the at least one notch, thereby preventing movement of the cannula hub relative to the hub strap.

9. The biopsy needle assembly of claim 2 , wherein the hub strap further includes at least one end wall to restrain the movement of the stylet hub within the inner channel.

10. The biopsy needle assembly of claim 1 , wherein the stylet further comprises a tissue sampling recess proximate the distal end thereof.

11. The biopsy needle assembly of claim 1 , in which the distal end of the stylet is sharpened so as to facilitate penetration of tissue.

12. The biopsy needle assembly of claim 1 , in which the distal end of the cannula is sharpened so as to facilitate penetration of tissue.

13. The biopsy needle assembly of claim 1 , in which the cannula hub, stylet hub and hub strap are constructed from a plastic material.

14. An integrated biopsy needle assembly comprising:

a cannula having a distal end and a proximal end, and a hollow cross-sectional therebetween;

a stylet having a distal end and a proximal end, the stylet being adapted for sliding movement within the cannula;

a cannula hub operatively fixed to the proximal end of the cannula;

a stylet hub operatively fixed to the proximal end of the stylet; and

a hub strap operably associated with the cannula hub and the stylet hub, wherein the cannula hub is operatively fixed to the hub strap and the stylet hub is oriented so as to be movable relative to the hub strap;

wherein the hub strap comprises a top member, at least one side wall and at least one bottom member, thereby forming an inner channel;

wherein the cannula hub and the stylet hub each comprise a base and a cap; and

wherein at least one of the cannula hub base and the stylet hub base has a width greater than the width of the hub strap.
