Biopsy arrangement

Abstract

A biopsy arrangement for taking a biopsy in a human or animal tissue, said biopsy arrangement comprising: —a needle arrangement () comprising an elongated inner needle part () and an elongated outer needle part (), which outer needle part () is a hollow member in which the inner needle part () fits coaxially, wherein the two needle parts can be provided in at least two different positions in relation to each other; —an activator () which is arranged in the biopsy arrangement () such that it can be moved within the biopsy arrangement, said activator () comprising: —a first activating part () which is configured to control a needle locking device () provided in the biopsy arrangement () to lock or not lock the inner needle part () and the outer needle part () to each other; and —a second activating part () which is configured to control a needle translation device () provided in the biopsy arrangement () to change a position of the inner () and outer needle parts () in relation to each other, said needle translation device () being connected to at least one of the inner or outer needle parts (), whereby a movement of the activator () within the biopsy arrangement () can affect a position of both the first and the second activating parts () whereby both the needle locking device () and the needle translation device () can be controlled.
