摘要： A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

摘要： A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.
