Event or Problem Description
Olympus medical systems corp.(omsc) was informed from the user facility that after the reprocessing of the unspecified endoscope with the subject device, it was found that the connecting tube was disconnected from the connecting tube connector.The user facility replaced the subject device to another connecting tube and reprocessed the endoscope again, because there was concern about detergency.This issue occurred with three connecting tubes (maj-1500) including the subject device in this report.There was no report of patient injury associated with this event.
Additional Manufacturer Narrative
This report is being supplemented to provide additional information based on the legal manufacturer's investigation and the subject device's inspection.The subject device was returned to, and evaluated by olympus.The customer's complaint was confirmed.The distal end of the device was inspected under a microscope and found the probe tip was broken.The missing probe was not returned for evaluation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.Based on the results of the legal manufacturer's investigation, the phenomenon likely occurred due to contact with a surgical instrument or the non-insulated area of the the grasping section.A review of the instruction manual identifies the following descriptions related to this event: - "do not activate output in seal & cut mode while the grasping section is closed without contacting tissue or vessel, or ensuring that tissue is transected.Otherwise, a local increase of the temperature due to a friction between the probe tip and the grasping section may result in various forms of damage in the probe tip and/or the tissue pad, such as premature wear, breakage, deformation, and/or falling off inside the body cavity and/or partial separating." - "when cutting and vessel sealing is performed in seal & cut mode, apply light tension on the tissue so that users can confirm it is transected.Also, stop activation immediately after tissue is transected.Otherwise, the grasping section, the tissue pad, or the probe tip may break and fall off, and partial separating of the tissue pad may occur due to a local increase of temperature caused by the friction between tissue pad and the probe tip during activation." - "the thunderbeat instrument should be used for soft tissue.Do not activate output while grasping hard tissue such as bone or highly calcified tissue, or hard objects such as metal clips, stapler, or other instruments (e.G., uterine manipulator, forceps, and others).Otherwise, it may cause the probe tip to be scratched or come into direct contact with the metal area of the grasping section as the heat generated by the friction between the hard object and the probe tip could cause wear/deforming/splitting/protruding/partial separating of the tissue pad.In turn, the probe may break before displaying an error window or generating an alarm tone." - "do not grasp or let the probe tip contact hard objects such as metal clips, stapler, or other instruments (e.G., uterine manipulator).Also, be careful to avoid contacting the probe tip with those accidentally.Particularly during activation, a scratch on the probe tip could occur due to ultrasonic vibration, which leads the probe tip to break and fall off into the body cavity.In addition, the high-frequency (rf bipolar) current flows through the metal and generates spark discharge, which may cause burns and decrease functionalities.".
