Patent ID: 10959709

Abstract:
The present invention relates to a biopsy assembly for obtaining a tissue sample, comprising an outer tubular cannula provided with an oblique distal tip, and a stylet adapted to be disposed axially within said cannula and having an oblique distal tip. The stylet is provided with a recess arranged along a side of the stylet which is adapted to receive the tissue sample. The assembly further comprises a housing for guiding and manipulating the proximal ends of the cannula and the stylet and is provided with a rotating member configured to rotate the stylet or cannula around a common axis, such that the cannula and the stylet are rotated relative to one another. The rotating member is configured to rotate the stylet and cannula relative to one another prior to tissue sampling, such that a most distal edge of the oblique distal tip of said cannula is arranged at the same side as the recess when the tissue sampling is performed.
