Abstract
A hand held instrument for harvesting a biopsy sample is provided. The instrument includes a housing, an annular blade on a distal end of said housing for cutting axially cutting a biopsy, a transverse blade unit for transversely cutting the biopsy, and a plunger unit positioned within the housing ejecting the biopsy sample away from inside the housing after said biopsy sample has been transversely cut.

A hand held instrument for harvesting biopsy comprising:
- a tubular like housing;
- an annular blade on a distal end of said housing for cutting axially cutting a biopsy;
- a transverse blade unit for cutting transversely said biopsy, said transverse blade unit including a blade holder with a pin in slot connection with at least 4 hemispherical transverse blades and said transverse blades having a pivotal connection with a capture head encircling said transverse blades, said pivotal connection with said capture head including a pin projecting from said capture head projecting through a hole in said blades, said pin being captured in an annular groove in said blade holder and said transverse blade unit being actuated by a linear motion push tab extending for said housing;
- and
- a plunger unit positioned within said housing pushing said biopsy from said housing, said plunger unit being actuated by pushing down on a head of said housing, and said plunger unit having a plunger formed by an upper and lower plungers connected together.
