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 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.
