Abstract

A biopsy device is disclosed that includes a housing maintaining a stylet and a cannula, a control device operable to actuate the stylet and the cannula with respect to the housing and a removable handle coupleable to the control device to load the stylet and the cannula, wherein the handle is configured to modify the device from to a loading configuration a delivery configuration such that the device has a reduced profile for obtaining a tissue sample.

Claims (42)

1. A biopsy device, comprising:

a housing maintaining a stylet and a cannula;

a control device operable to actuate the stylet and the cannula with respect to the housing, the control device including tabs extending through slots in the housing; and

a removable handle configured to facilitate arming of coupleable to the control device so as to load the stylet and the cannula by overcoming a biasing force imparted by a biasing member,

wherein the handle is configured to modify the device from a loading configuration to a delivery configuration such that the device has a reduced profile for obtaining a tissue sample, and

wherein the handle is adapted to engage the tabs in the loading configuration.

2. The biopsy device of claim 1 wherein the handle is configured to be foldable with respect to the housing.

3. The biopsy device of claim 1 , wherein the handle includes a body defining an inner perimeter configured to be positioned around the housing.

4. The biopsy device of claim 3 , wherein the handle further includes first and second wings extending from the body, the wings configured to be grasped by a user.

5. The biopsy device of claim 1 , further comprising:

a cannula insertion guide co-axially aligned with and accommodating the stylet and the cannula;

a longitudinal adjusting element coupled to the housing,

wherein the longitudinal adjusting element is adapted to co-axially adjust the position of the cannula insertion guide relative to the stylet and the cannula.

6. The biopsy device of claim 1 , wherein the housing includes a first button of the control device configured to sequentially actuate the stylet and the cannula and a second button configured to independently actuate the stylet.

7. The biopsy device of claim 1 , wherein the handle includes foldable wings extending from the housing, the wings being folded relative to the housing to modify the device to the delivery configuration.

8. A biopsy device, comprising:

a housing maintaining a stylet and a cannula;

a control device operable to actuate the stylet and the cannula with respect to the housing; and

a handle comprising a plurality of wings each foldable about a hinge and configured to facilitate arming of the control device so as to load the stylet and the cannula by overcoming a biasing force imparted by a biasing member,

wherein the handle is configured to modify the device from a loading configuration to a delivery configuration such that the device has a reduced profile for obtaining a tissue sample,

wherein the wings are configured to be grasped by a user.

9. The biopsy device of claim 8 wherein the wings are configured to be foldable with respect to the housing.

10. The biopsy device of claim 8 , wherein the control device includes tabs extending through slots in the housing, the handle adapted to engage the tabs in the loading configuration.

11. The biopsy device of claim 8 , wherein the handle includes a body defining an inner perimeter configured to be positioned around the housing.

12. The biopsy device of claim 8 , further comprising:

a cannula insertion guide co-axially aligned with and accommodating the stylet and the cannula;

a longitudinal adjusting element coupled to the housing,

wherein the longitudinal adjusting element is adapted to co-axially adjust the position of the cannula insertion guide relative to the stylet and the cannula.

13. The biopsy device of claim 8 , wherein the housing includes a first button of the control device configured to sequentially actuate the stylet and the cannula and a second button configured to independently actuate the stylet.

14. The biopsy device of claim 8 , wherein the wings extend from the housing, the wings being folded relative to the housing to modify the device to the delivery configuration.

15. The biopsy device of claim 8 , wherein the handle is configured to modify the device from a loading configuration to a delivery configuration such that the device has a reduced profile around the housing for obtaining a tissue sample.

16. The biopsy device of claim 8 , wherein the plurality of wings comprises a first wing and a second wing, the first and second wing extending from opposing sides of the housing.

17. A biopsy device, comprising:

a housing maintaining a stylet and a cannula, the housing including upper and lower slots;

a control device operable to actuate the stylet and the cannula, the control device including upper and lower tabs extending through the upper and lower slots of the housing, respectively; and

a removable handle including an inner perimeter shaped to be positioned around the housing, a body configured to engage the upper and lower tabs of the control device, and first and second wings each foldable about a hinge and extending from the body, the first and second wings shaped to be grasped by a user to facilitate arming of the control device to load the stylet and cannula by overcoming a biasing force imparted by a biasing member when the body engages the upper and lower tabs of the control device.

18. The biopsy device of claim 17 , further comprising:

a cannula insertion guide co-axially aligned with and accommodating the stylet and the cannula;

a longitudinal adjusting element coupled to the housing,

wherein the longitudinal adjusting element is adapted to co-axially adjust the position of the cannula insertion guide relative to the stylet and the cannula.

19. The biopsy device of claim 17 , wherein the housing includes a first button of the control device configured to sequentially actuate the stylet and the cannula and a second button configured to independently actuate the stylet.

20. The biopsy device of claim 19 , wherein the first button and the second button are positioned on a side of the housing maintaining one of the upper and lower slots.
