Patent ID: 8518044

Claim:
A low cost disposable flexible reamer assembly for medical applications, comprising: a. a torque transmitting flexible cylindrically braided shaft in the form of a tube having a first end and second end, said cylindrically braided shaft being metallic; b. said first end of the flexible cylindrically braided shaft having a bonded first end element with male screw threads of sufficient length for attachment to said modular reamer assembly; c. said male element screw threads being counter clockwise, to prevent loosening of said modular reamer assembly during the bone reaming procedure; d. said flexible cylindrically braided shaft having a bonded second end element with a matching fitting sized to fit to a chuck of a power drive; e. said cylindrically braided shaft having a central aperture that carries a polymeric flexible tube element with a central aperture, said polymeric flexible tube element extending through said cylindrically braided shaft; f. a guide pin adapted to be affixed to a bone cavity, the guide pin being adapted to enter a central aperture of said modular reamer assembly and extend into the central aperture of polymeric tube element with close diametrical tolerance, and to set the direction of reaming action as guided by the surgeon; and g. said reamer being hollow; whereby a surgeon guides said low cost disposable flexible shaft with said modular reamer to reach a precise aim point within the bone cavity set by the guide pin positioned along the reaming direction selected by the surgeon.
