A biopsy arrangement for taking a biopsy in a human or animal tissue, said biopsy arrangement comprising: a driver unit; and at least two different types of probes which can be releasably connected to the driver unit, said at least two different types of probes comprising at least a first probe type and a second probe type, wherein said driver unit comprises at least two different probe controlling devices which are controlling different probe modules in a connected probe, said at least two different probe controlling devices comprising a suction generating device and a needle moving device, and wherein probe modules of the first probe type comprise a suction transferring module and at least one needle manipulating module, wherein said suction transferring module is configured for transferring a suction from the suction generating device of the driver unit to a needle of the first probe type and wherein said at least one needle manipulating module is a first probe type needle manipulating module configured for providing longitudinal and/or rotational movement to at least a part of the needle of the first probe type, and wherein probe modules of the second probe type comprise at least one needle manipulating module, which is a second probe type spring loaded needle manipulating module which is configured for providing a spring loaded longitudinal movement to at least a part of a needle of the second probe type.

Biopsy arrangement

The invention relates to a biopsy tool () for removing a tissue sample. The biopsy tool () is configured to be altered between an incision state and a severing state. The biopsy tool () comprises: an elongated outer tubular member () wherein a distal end () of the outer tubular member () comprises a cutting edge (); an elongated inner tubular member () arranged inside the outer tubular member (); and a cutting wire (). The outer and inner tubular members () are rotatable in relation to each other around a rotational axis (R). The outer tubular member () comprises a first aperture () and the inner tubular member () comprises a second aperture (). The cutting wire () is spring biased and configured to be arranged in association with the first aperture () of the outer tubular member (). The biopsy tool () is configured to obtain the severing state by rotational movement of the outer tubular member () and/or the inner tubular member (), so that the first aperture () and the second aperture () overlap, whereby the cutting wire () is displaced perpendicularly to the rotational axis (R). The invention also relates to a method for removing a tissue sample by using a biopsy tool ().

Biopsy tool and method for removing a tissue sample

The present invention relates to an arrangement for taking a biopsy in a human or animal tissue, comprising an elongated hollow member having a circular cross-section in a plane perpendicular to a longitudinal axis, and a circular cutting edge at distal end. The circular cutting edge is provided with at least one cutting slit, running from the cutting edge in a proximal direction of the elongated hollow member. The arrangement further comprises a rotational member configured to apply rotational movement to the hollow member, wherein the rotational movement is applied in accordance to a rotational procedure such that the hollow member is rotated in one direction a predefined amount of rotations, and thereafter rotated in an opposite direction the same amount of rotations.

Distal tip tissue sampling arrangement

An arrangement for taking a biopsy in a human or animal tissue, comprising an elongated hollow member, comprising a proximal end and a distal end, wherein the elongated hollow member has a circular cross-section in a plane perpendicular to a longitudinal axis of said hollow member, and said distal end is provided with a cutting edge. The arrangement further comprising an elongated rod configured to fit inside said elongated hollow member, a longitudinal movement generating unit configured to generate an oscillating longitudinal movement of said elongated hollow member, or of an assembly of said elongated hollow member and said elongated rod via a connection assembly. The connection assembly is provided configured to assemble the elongated hollow member and the elongated rod by detachably fixating said elongated rod inside said elongated hollow member in a longitudinal position relative to said elongated hollow member.
