Abstract

A biopsy device for taking a 3D biopsy may comprise an outer sleeve, a hollow main shaft, a biopsy tube and a tube shaft. The hollow main shaft may have a distal end portion with a sideward facing notch, and the main shaft may be adapted to be accommodated within the outer sleeve. The biopsy tube may be provided for receiving cut and thus isolated tissue. A proximal end of the biopsy tube may be releasably attachable to a distal end of the tube shaft so that the biopsy tube is movable together with the tube shaft within the hollow main shaft between a proximal position in which the biopsy tube is not located in the notch, and a distal position in which the biopsy tube is located in the notch.

Claims14

Dependent claims

A biopsy device comprising

an outer sleeve,
a hollow main shaft, the main shaft having a distal end portion, wherein a sideward facing notch is formed in the main shaft in the distal end portion of the main shaft, wherein the main shaft is accommodated within the outer sleeve,
wherein the outer sleeve is movable relative to the main shaft between a first position in which the notch is not covered by the outer sleeve, and a second position in which the notch is covered by the outer sleeve,
a tube shaft movably accommodated within the hollow main shaft, and
a biopsy tube for receiving tissue to be resected, wherein a proximal end of the biopsy tube is releasably attachable to a distal end of the tube shaft so that the biopsy tube is movable together with the tube shaft within the hollow main shaft between a proximal position in which the biopsy tube is not located in the notch, and a distal position in which the biopsy tube is located in the notch.
