Description : Arthroscopic Shaver failure
Problem : Shaver failed during surgery. Fractured piece was removed from
the shoulder by follow-on surgery and analyzed.
Analysis : Failure was caused by defective brazing that had bonded the outer
surface of the failed shaver tip to the inner surface of the
arthroscopic tool body.
Resolution & Recommendations :
Develop a brazing process validation plan and use NDI technique to
ensure the presence of sufficient braze volume.
