摘要：
A biopsy device is proposed comprising a shaft and a tubular member. The shaft is movably, i.e. rotatably as well as shiftably accommodated within the tubular member and comprises a spiral at a distal end portion of the shaft, wherein the spiral is formed by a twisted sheet. Such a spiral may be considered as a laterally open thread having no solid core.
