Abstract

The invention provides for a biopsy device comprising a body, a cutting edge, and at least one of; a movable safety cover, a depth adjustment member, and an arrangement for moving the cutting edge relative to a skin engaging surface.

Claims

1. A biopsy device comprising:

a body;

a cutting edge; and

at least one of;

a safety cover selectively lockable in at least one retracted position;

a safety cover selectively movable to at least one retracted position;

a safety cover axially retainable in at least one retracted position;

a safety cover axially lockable in at least one retracted position;

a movable safety cover;

a depth adjustment member; and

an arrangement for moving the cutting edge relative to a skin engaging surface.

2. The device of claim 1, wherein the body comprises the cutting edge.

3. The device of claim 1, wherein the device utilizes the depth adjustment member.

4. The device of claim 3, wherein the depth adjustment member is mounted to the body.

5. The device of claim 3, wherein the depth adjustment member is movably mounted to the body.

6. The device of claim 1, wherein the device utilizes the movable safety cover.

7. The device of claim 6, wherein the movable safety cover covers the cutting edge when in an initial position.

8. The device of claim 3, wherein the movable safety cover is movably mounted to a skin contacting end of the body.

9. The device of claim 1, wherein the device utilizes the depth adjustment member and the movable safety cover.

10. The device of claim 9, wherein movement of the movable safety cover is limited by the depth adjustment member.

11. The device of claim 1, wherein the device utilizes the movable safety cover and at least one spring for biasing the movable safety cover.

12. The device of claim 1, wherein the device further comprises a device for preventing reuse.

13. The device of claim 1, wherein the device further comprises a device movable from an initial position to a position preventing reuse of the device.

14. The device of claim 1, wherein the body comprises an elongated generally cylindrical body.

19. A method making the device of claim 1, the method comprising:

arranging a safety shield on a body.

15. A biopsy device comprising:

a body;

a skin engaging surface;

a cutting edge; and

at least one of;

an arrangement for moving the cutting edge relative to the skin engaging surface;

an arrangement for moving the cutting edge at least axially toward the skin engaging surface;

an arrangement for causing rotation of at least one of the cutting edge and the body; and

an arrangement for allowing at least one of the cutting edge and the body to be coupled to a rotatable portion of a powered device.

16. The device of claim 15, wherein the skin engaging surface is arranged on a cover mounted to the body and the cutting edge is arranged on an axially moveable holder at least partially disposed in the body.

17. The device of claim 15, further comprising a trigger system and a device for moving the cutting edge to a trigger-set position.

18. The device of claim 15, further comprising a depth adjustment system.

20. A single-use or disposable biopsy device comprising:

a cutting edge; and

a safety cover,

wherein at least one of;

the safety cover is movable relative to the cutting edge; and

the cutting edge is movable relative to the safety cover.
