A biopsy tool and method for removing a tissue sample

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).

Description

technical field [0001] The present invention relates to biopsy tools for removing tissue samples. The invention also relates to methods of removing tissue samples by using such biopsy tools. Background technique [0002] A biopsy involves taking a sample of tissue for analysis. Biopsies can be performed with a variety of instruments and methods, and can take tissue samples from almost anywhere on or inside the body, including skin, organs, and other structures. A biopsy removes cells and tissue that are analyzed to identify abnormal cells, which can help diagnose a particular condition. Skin biopsies are commonly used to diagnose skin disorders such as inflammatory diseases, autoimmune diseases, skin cancer, and other cancers in the skin. It can also be used for radical resection of small melanoma lesions. Cancer is the leading cause of death worldwide, and the number of cancer diagnoses is increasing. Therefore, in order to detect cancer at an early stage, it is very i...
