Abstract
Abstract A biopsy device, primarily for cervical biopsy, comprising a generally arrowhead-shaped tool substantially V-shaped in cross section and having outer longitudinal knife edges intersecting at the sharp tip of the device. In use, the device is inserted into the tissue from which the specimen is to be taken. To separate the specimen from the adjacent tissue, a scalpel is run forwardly along longitudinal converging guide means- a groove or ribprovided on each inside face of the device just below each knife edge. The two converging guide grooves or ribs terminate at a central hole, which functions as a stop to limit forward movement of the scalpel. The separated specimen is thus held in the receptacle provided by the V-cross section tool, in which it is carried for removal from the body.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
79 words
In a biopsy instrument, a generally pointed device having converging cutting knife edges, means defining a receptacle between said knife edges comprising two substantially flat planar portions disposed at an angle to each other intersecting along a longitudinally extending line to provide a tapered, substantially V-shape in transverse cross section, said converging cutting knife edges being respectively positioned at the outermost longitudinal edges of the planar portions, and means disposed between the knife edges for guiding a cutting tool.
Claim 2
Dependent Claim
