On (b)(6) 2014 the hospital ordered parts to complete the required repair.The repair was completed by a 3rd party company.No additional info about the repair or the incident was provided to maquet.The back plate is mobilized on the table top by means of a form closure clamp.To adjust the back plate, an operator has to press a safety push-button, open the eccentric levers on each side of the tabletop, adjust the position of the back plate and then retighten the eccentric lever to secure the unit in place.The product is designed so that if one of the eccentric mechanisms is damaged or unsecured the other one should sufficiently support the pt.However, if these clamps are not properly secured, the proper interlocking of the tooth locking mechanism may be impeded, resting in excessive wear of the teeth and if left unresolved, the potential for slippage of the tooth lock washer as reported.Because the wear down of the components observed is a gradual process, the customer could have prevented this event with proper maintenance and inspection.Maquet (b)(4) provides product failure investigation, analysis and resolution for the device described in this report.
