SURGICAL REAMER AND METHOD OF USING SAME

摘要

A device for expedited reaming of a medullary canal and method of using the same are disclosed. The device includes a reamer head (20; 20') connected at the distal end of a rotatable drive shaft (102). The reamer head (20; 20') h as a cutting head (40) with a plurality of blades (41) and flutes therebetween. Each blade (41) has a front cutting portion. At least some of the blades hav e a front cutting portion that includes at least two and preferably at least three planar surfaces (51, 52, 53). The blades can also include a side cutti ng portion (44). The disclosed method for removing material from the medullary canal of a bone includes the steps of reaming an area of the medullary canal to remove material; irrigating the material to be removed while reaming to reduce generation of heat and move removed material from the reaming area; a nd aspirating the removed material while reaming to create a negative intramedullary canal pressure to assist in the removal of the material.
