Title:
組織試料を切除するための生検ツールおよび方法
Document Type and Number:
Japanese Patent JP7392001
Kind Code:
B2
Abstract:
The invention relates to a biopsy tool (10) for removing a tissue sample. The biopsy tool (10) is configured to be altered between an incision state and a severing state. The biopsy tool (10) comprises: an elongated outer tubular member (20) wherein a distal end (22) of the outer tubular member (20) comprises a cutting edge (24); an elongated inner tubular member (30) arranged inside the outer tubular member (20); and a cutting wire (40). The outer and inner tubular members (20, 30) are rotatable in relation to each other around a rotational axis (R). The outer tubular member (20) comprises a first aperture (25) and the inner tubular member (30) comprises a second aperture (35). The cutting wire (40) is spring biased and configured to be arranged in association with the first aperture (25) of the outer tubular member (20). The biopsy tool (10) is configured to obtain the severing state by rotational movement of the outer tubular member (20) and/or the inner tubular member (30), so that the first aperture (25) and the second aperture (35) overlap, whereby the cutting wire (40) 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 (10).
