摘要

The present invention provides a surgical reamer (10), surgical reamer system, and kit including a surgical reamer. The surgical reamer has a domed shell (12) extending from the apex to the rim (13), a rotation axis (1), cutting teeth (14) disposed around the domed shell wherein a first connecting bar (15) having a first longitudinal axis and a first diameter is located on the inside surface of the domed shell, with its first longitudinal axis and a first diameter is located on the inside surface of the domed shell, with its first longitudinal axis being adjacent or closely adjacent to the rim and in which a second connecting bar (16) having a second longitudinal axis and a second diameter is located on the inside surface of the domed shell and spaced apart from the first connecting bar.

主权项

1. A surgical reamer comprising: a continuous, fully hemispherical domed shell extending from the apex to the rim, a rotation axis, cutting teeth disposed around the domed shell wherein a first linear connecting bar having a first longitudinal axis and a first diameter is located on the inside surface of the domed shell, with its first longitudinal axis being adjacent or closely adjacent to the rim and wherein a second linear connecting bar having a second longitudinal axis and a second diameter is located on the inside surface of the domed shell and spaced apart by a distance from the first connecting bar, wherein an angle between the first longitudinal axis and the second longitudinal axis is 90 degrees or less, wherein at least a portion of a first cross-section of the first diameter is disposed below the rim and a second cross-section of the first diameter is disposed above the rim, and wherein a second cross-section, of the second diameter is fully disposed below the rim and the first diameter.
