1. A surgical bone rasp for the surgical working of bone material by oscillating movement of said bone rasp for preparing a bone to receive a prosthesis, said surgical bone rasp comprising:
- a toothed, elongate working section having teeth with cutting edges, said teeth extending from a distal end to a proximal end of said working section, anda connecting section arranged at said proximal end for the connection of said bone rasp to an impact tool, wherein said toothed working section including said teeth and cutting edges is made of only plastic or carbon fiber reinforced plastic material, andwherein said toothed, elongate working section is provided with a longitudinally extending bore with a distal and proximal end, said bore being open at the distal end of said working section and being open at the proximal end of said working section, and said connecting section is arranged at an angle to said longitudinal bore at said proximal end of said working section such that the proximal end opening of said bore in said working section is connectable to a flushing and suction line when said connecting section is connected to an impact tool.
