Biopsy device incorporating an adjustable probe sleeve |
摘要 |
Devices and methods for varying the size of a tissue sample in a biopsy device are disclosed. The biopsy device includes a needle with a tissue aperture and an inner cutter which translates within the needle. The inner cutter may be controlled to selectively block the aperture thereby varying the sample size. A half cylindrical sleeve may be resiliently attached to the exterior of the needle in order to block the aperture. The sleeve includes gripping flanges on its bottom surface, and a beveled distal tip configured to avoid damage from the inner cutter. The distal tip may include an inner metallic guide or may be heightened to avoid contact with the cutter.
