Tissue cutting device

Devices and methods for efficient severing or cutting of a material or substance, such as soft tissue, suitable for use in open surgical and/or minimally invasive procedures, such as percutaneous procedures in breast tissue, are disclosed. A tissue cutting device may generally include a probe, a cutting assembly configured to be in a storage configuration or a preformed cutting configuration for cutting the specimen, a tissue fixator and a specimen retriever. When in the cutting configuration, the cutting assembly may be configured to move and cut the specimen relative to the tissue fixator along an axis of the probe. The tissue fixator may facilitate in stabilizing a region of tissue during cutting of the specimen. The region of tissue may be the specimen and/or tissue adjacent to and/or near the specimen. The specimen retriever may optionally be coupled to the cutting assembly and integrated as part of the tissue fixator.
