Filed:

Aug 11, 2003

Appl. No.:

10/638519

Inventors:

Salvatore Privitera - West Chester OH, US

Assignee:

Devicor Medical Products, Inc. - Cincinnati OH

International Classification:

A61B 17/32

US Classification:

606167, 606170

Abstract:

A handheld biopsy device is provided for the collection of soft tissue samples from a surgical patient. In a preferred embodiment, the biopsy device comprises a handpiece, a fluid collection system, and a power transmission source. The handpiece is configured for grasping by a single hand, and being independently manipulatable by hand for movement of the instrument toward and away from the patient. An elongated piercer extends from the distal end of the handpiece. The piercer has a sharpened distal end for entering the tissue and a port located proximal to the sharpened distal end for receiving a portion of tissue mass. An elongated cutter is disposed coaxially relative to a piercer lumen of the piercer. A distal blade of the cutter slides distally past the port of the piercer to severe the tissue portion drawn into the port by vacuum. The cutter is retracted to a most proximal position for removal of the tissue portion from a cutter lumen of the cutter.
