POLYMER 4-IN-1 FEMORAL CUTTING BLOCK |
摘要 |
An orthopaedic surgical instrument including a polymer 4-in-1 femoral cutting block having a chamfer cutting slot defined therein, and a chamfer cutting guide assembly secured within the chamfer cutting slot. The chamfer cutting guide assembly includes a first planar surface, a second planar surface spaced apart from, and extending parallel to, the first planar surface, a third planar surface connected to the second planar surface and extending at an angle relative to the first planar surface and a fourth planar surface connected to the first planar surface and extending parallel to the third planar surface. The first planar surface and the second planar surface define a first metallic planar cutting guide, and the third planar surface and the fourth planar surface define a second metallic planar cutting guide. The chamfer cutting guide assembly may include a pair of metallic bushings. |

1. An orthopaedic surgical instrument comprising:
a polymer 4-in-1 femoral cutting block having a chamfer cutting slot defined therein, a first metallic planar cutting guide secured within the chamfer cutting slot, the first metallic planar cutting guide being defined by (i) a first planar surface and (ii) a second planar surface spaced apart from, and extending parallel to, the first planar surface, a second metallic planar cutting guide secured within the chamfer cutting slot, the second metallic planar cutting guide being defined by (i) a third planar surface extending at an oblique angle relative to the first planar surface, and (ii) a fourth planar surface extending parallel to, spaced apart from, the third planar surface, a first metallic bushing secured within the chamfer cutting slot of the polymer 4-in-1 femoral cutting block, an outer surface of the first metallic bushing being positioned at a lateral end of each of the first and second metallic planar cutting guides, and a second metallic bushing secured within the chamfer cutting slot of the polymer 4-in-1 femoral cutting block, an outer surface of the second metallic bushing being positioned at a medial end of each of the first and second metallic planar cutting guides. |
