Abstract

A biopsy device includes a body, a needle, a cutter, and a cutter drive assembly. Body includes an outer housing. The needle extends distally from the body. The cutter is configured to rotate and translate relative to the needle. The cutter drive assembly includes a cutter overmold secured to a portion of the cutter. The cutter overmold includes a threaded portion and one or more channels. The threaded portion is configured to drive translation of the cutter. The one or more channels are configured to drive rotation of the cutter. The outer housing defines a resilient member extending inwardly from an inner surface of the outer housing.
