Double cannulated osteotome

摘要

DOUBLE CANNULATED OSTEOTOME A cannulated osteotome (11) for cutting a bone surface in which two circular depressions have been previously reamed comprising a cutting blade (19) in the form of a continuous loop having two arcuate end surfaces (25a, 25b) and two straight lateral surfaces (23a, 23b) that depends from a body that includes two cannulae (41) in the form of two parallel passageways that extend transversely through the body. Stops (27) extend beyond the opposite arcuate ends of the cutting blade which determine the depth to which the cutting blade can be inserted into the surface of bone from which the circular depressions have been reamed. There is described a method of inserting an implant having a substantially flat undersurface from which two pegs protrude into a surface of a bone using such an osteotome.
