| 摘要 |
An orthopedic reamer cutting tool (10) is disclosed that incorporates a first material (41) and a second material (47) such as graphene having a greater coefficient of thermal conductivity than the first material, to remove heat generated at the tissue cutting surface during use. The reamer is constructed having a hemispherical cutting shell (12) that extends from an equatorial base (14) to an apex (20) at a distal end (22). A plurality of cutting teeth (40), each having a tissue cutting surface (42), extend from the exterior of the cutting shell. A reamer driver interface (32) may be positioned spanning the diameter of the reamer base. The second material, having increased thermal conductivity, may be applied to the interior (28) and/or exterior (26) shell surfaces. In addition, the second material may be incorporated within the shell or the driver interface. |
