BIOPSY INSTRUMENT
Document Type and Number:
Japanese Patent JPS63279828
Kind Code:
A
Abstract:
A biopsy device including a two- or multi-lumen biopsy cannula has a biopsy channel of constant cross section over its entire length and at least one application channel. On its proximal end, it is provided with connection facilities for an aspiration device and at least one application device. In order to enable the collection of tissue specimens of an unchanged structure with the most careful handling possible of the tissue and the application of auxiliary substances into the puncture channel without tissue specimens getting into the application cannula and obstructing the same, the cutting edge is formed by an acute-angularly designed end of the biopsy channel wall alone. At least one application channel is formed by a tube eccentrically slipped over the biopsy channel wall. The biopsy channel wall projects out of the tube with its cutting edge and the tube end encloses an obtuse angle with the biopsy channel.
