The user facility reported that the table articulated at an abnormal angle prior to the start of a patient procedure.No injury to patient or staff was reported in relation to the reported event.A steris service technician arrived at the user facility, inspected the surgical table and found that one of the table's set screws had loosened over time, allowing the pivot pin to detach from the table.The technician stated the pin and set screw could not be located anywhere in or around the table base.The technician removed the table from service for return to steris service engineering for further evaluation.An ot1200 table was provided to the facility in the interim for use.Each ot1000 series orthopedic surgical table contains four pivot pin assemblies which are comprised of a pivot pin and set screw.If the set screw is not properly installed into the pivot pin, the pin may not operate as designed, preventing the table from properly performing table articulations.In extreme situations, missing or improperly installed set screws can cause the table top to tilt at an extreme or abnormal angle during use.The issue identified with the user facility's ot1200 table was investigated by steris quality and engineering.While this was determined to be an isolated occurrence, steris has made the decision to inspect all ot1000 series surgical tables distributed to customers to ensure proper set screw installation.Steris corporation is implementing a field correction in which steris service technicians will remove and inspect each of the table's four pivot pin assemblies, verify proper set screw engagement, and reinstall the pivot pin on all affected ot1000 series orthopedic surgical tables.These inspections will be completed and monitored under steris field correction #1043572-05062016-001-c.
