Biopsy system with a core collector that remains radially centered in an outer cannula while severing a tissue sample

A core collector is shaped as a crescent in cross-section and has lateral sides formed into axially extending rows of axially spaced teeth. The arc angle of the crescent shape is sufficient to keep the core collector radially centered in a cannula by having the crescent's lateral sides bear aga...

Zusammenfassung:A core collector is shaped as a crescent in cross-section and has lateral sides formed into axially extending rows of axially spaced teeth. The arc angle of the crescent shape is sufficient to keep the core collector radially centered in a cannula by having the crescent's lateral sides bear against the inside of the cannula. The set of a core collector and cannula can be used in a known biopsy system to replace the known cannula and core collector of can be used in a new core biopsy instrument.
