Mechanism for dicing cartilage
A cartilage dicing device according to an embodiment of the present invention includes blades disposed in a housing configured to mitigate entry of the cartilage into the housing of the device. The device includes a number of circular blades used to dice the cartilage in a uniform fashion. The blades are disposed in a housing with a base that prevents the tissue from entering the body of the housing, which ensures that more of the tissue is available to be diced and used in a medical procedure. The blades are spaced at uniform distance.
