FIELD: medical engineering. SUBSTANCE: device has handle, hollow tube and internal tie-rod. The tie-rod is mounted inside the hollow tube and is connected to the handle and working members having cutting edge. The working members are turned outwards from internal tie-rod axis and are arranged equidistantly one from another all over diameter. The working members enable one to open to the internal diameter of an internal organ by coming in engagement with conic surface and internal tie-rod bearing supporting casing. The casing is engageable with internal surface of each working member allowing the working members to restore their initial positions. EFFECT: allowed biopsy to be taken from the whole internal surface of tubular organ. 2 dwg |
