The National Medical Products Administration (NMPA) issued a recall event report on July 21, 2010, regarding Medical Linear Accelerators manufactured by Varian Medical Systems, Inc., with its Chinese responsible unit being Varian Medical Systems TRADING Co., Ltd. The recall, reported on July 2, 2010, involved 275 units globally of the Clinac 600C/D model, used for patient radiotherapy. The main issue identified was "Clinac Abnormalities in the aperture and treatment bed," which could lead to "incorrect patient or field positioning," posing a risk to patient safety during treatment. As a corrective action under the NMPA's regulatory framework, Varian's China Customer Support Center was required to issue an "Emergency Notice on On-site Safety Matters" to all affected Chinese users. This notification aimed to alert users to the potential hazard and reinforce safety protocols, with the notification process to Chinese users confirmed as completed.
