Title:
可撓性を有する先端部を備えた医用器具
Document Type and Number:
Japanese Patent JP3920219
Kind Code:
B2
Abstract:
A biopsy device includes a flexible distal portion for obtaining a biopsy sample. The device includes a coring cannula defining a coring relief notch adjacent its distal end having a length longer than a diameter of the cannula. A wire is slidably disposable within the lumen of the coring cannula and defines a sampling cavity adjacent its distal end. A wire relief notch is positioned adjacent the sampling cavity that has a length longer than its width. A firing mechanism engaged to the proximal ends of the coring cannula and the wire is operable to move the coring cannula relative to the wire between a first position retracted within the lumen so that the coring cannula covers the sampling cavity and a second position wherein the distal end of the wire is extended away from the coring cannula to trap tissue from the biopsy site in the cavity.
