Abstract

A biopsy device with a hollow shaft is suggested, the shaft having a wall and a distal end portion, wherein a sidewardly facing notch is formed in the distal end portion. At least two optical fibers are arranged in the wall of the shaft so that end surfaces of the fibers are arranged in a longitudinal direction at opposite positions with respect to the notch.

Claims

1. A biopsy device comprising

a hollow shaft, the shaft having a wall and a distal end portion, wherein a sidewardly facing notch is formed in the distal end portion,

at least two optical fibers arranged for sensing within a volume between respective end surfaces of the optical fibers, wherein the fibers are arranged in the wall of the shaft so that the respective end surfaces of the fibers are arranged in a longitudinal direction of the shaft at opposite positions with respect to the notch, and wherein the respective end surfaces of the optical fibers are arranged outside the notch, and

a cutting element being movably accommodated within the hollow shaft.

2. The biopsy device of claim 1, wherein the end surface of at least one of the optical fibers is inclined relative to a longitudinal axis of the hollow shaft.

3. The biopsy device of claim 2, wherein a reflective layer is provided at the inclined end surface of the at least one optical fiber.

4. The biopsy device of claim 2, wherein an additional optical fiber is arranged in the shaft in such a way that the additional optical fiber and the at least one of the optical fibers are optically coupled by the inclined end surface.

5. The biopsy device of claim 1, further comprising at least two additional optical fibers being arranged in a lateral direction at opposite positions with respect to the notch.

6. The biopsy device of claim 5, wherein the at least two optical fibers and the at least two additional optical fibers are arranged in a regular pattern.

7. The biopsy device of claim 1, wherein the at least two optical fibers include at least one source fiber for emitting light and at least one detector fiber for receiving light.

8. The biopsy device of claim 7, wherein the biopsy device further comprises a channel for injecting or extracting a fluid.

9. The biopsy device of claim 1, further comprising a suction device for applying vacuum, wherein the biopsy device further comprises a tissue retraction channel, wherein the suction device is adapted to apply vacuum to the channel.

10. The biopsy device of claim 1, further comprising a console including a light source, a light detector and a processing unit for processing the signals provided by the light detector, the console being adapted for in-vivo tissue inspection.

11. The biopsy device of claim 1, further comprising a means for electromagnetic tracking.

12. The biopsy device of claim 11, further comprising a radiopaque material at the distal end portion of the shaft.

13. The biopsy device of claim 12, wherein the distal end portion of the shaft is configured for cauterization.
