A manual compression device designed to flatten, compact, or sculpt implantable tissues and tissue reconstructive materials (e.g., bone, cartilage, bone/fascia graft, gel foam) prior to their use in a surgical procedure. It may be referred to as a tissue crusher and is typically in the form of two hinged plates with a tightening mechanism (e.g., screws) to press the plates together with the material between, or a pliers-like device with jaws that compress. It is typically made of metal. This is a reusable device.
