33. When you�re called down to the OR because the endoscope system isn�t operating well, it�s very important to quickly isolate the failure mode so the right component can be fixed. Similarly during preventive maintenance, you need to know what�s working right and what�s not, so that the proper device can be sent out and the repairs done in a cost-effective manner. There really aren�t many different things that can go wrong as a result of hospital personnel and procedures. Unfortunately, what can go wrong is often catastrophic. You�ll notice that the bulk of failure modes are the result of incorrect actions during repair, when the lens systems and fiberoptics may be worked on. This is more common than you may suspect. There are at least 150 third-party endoscope repair companies in the United States alone. The quality of work ranges from excellent to well� less than excellent. That�s why we don�t want to wait until the scope is in a patient to check the device quality.

34. Companies do an excellent job in providing you with tools to validate and perform preventive maintenance on virtually all of your hospital equipment. Unfortunately, the same can�t be said for optics. Biomeds have sometimes adapted various generalized optical test equipment like photometers to try to get some quantitative data but scopes are quite unique optical devices and its very difficult to get meaningful data with what is available commercially. How many people here get involved in endoscope repair? Do scopes go through your department before going out for repair?Companies do an excellent job in providing you with tools to validate and perform preventive maintenance on virtually all of your hospital equipment.

35. I�d like to discuss some more difficult measurements that are no less important to the surgeon. The first test is system leakage or a broken optical component.I�d like to discuss some more difficult measurements that are no less important to the surgeon.

36. Most hospitals have a leak tester for identifying mechanical leakage in their flexible scopes. This is a really good investment because if the leak is identified before the scope is flooded with sterilization liquids, the cost of repair may be thousands of dollars less expensive.Most hospitals have a leak tester for identifying mechanical leakage in their flexible scopes.

37. Rigid scopes can also leak but aren�t able to be checked with a mechanical leak tester. Fortunately, there are simple devices that can be used for looking inside the scope on each of the lens surfaces in the shaft. Here�s a device that Lighthouse has developed, the ELT-1. It�s an inexpensive and simple endoscope testing device which lets you see if there is any moisture inside the scope or if a lens is broken or the adhesive separated.Rigid scopes can also leak but aren�t able to be checked with a mechanical leak tester.

38. Lighthouse Imaging worked closely with Sonora Medical Systems to design a product that biomeds can use for testing the optics and fiberoptics used in your hospital. Sonora recently introduced this product, called The Firefly, to test the light levels throughout endoscope systems. So, basically, the biomed measures the output of the lightsource, then measures both the lightsource and the light guide, and then finally the lightsource, light guide, and endoscope. In this way, you have a way of isolating which portion of the system has a problem and quickly and cost-effectively troubleshooting it. Ideally, you would measure your equipment when its operating correctly and perform regular preventive maintenance to track equipment degradation before it becomes unusable. We also have typical data that is provided with the Firefly in case the �as-new� measurements are not available for a particular device.Lighthouse Imaging worked closely with Sonora Medical Systems to design a product that biomeds can use for testing the optics and fiberoptics used in your hospital.

39. So, I wouldn�t tell you about this technique if I didn�t have a piece of equipment that would measure MTF. The EndoBench has been in production for more than 10 years and has proven very useful in performing rigorous quality measurements on endoscopes. Most of the EndoBenches sold have gone to manufacturing facilities and this is what its been optimized for. In fact, most of the rigid endoscopes sold in this country are manufactured at facilities that have at least 1 EndoBench. As you would expect, this product tend to be quite complicated and expensive. I want to give you a sneak preview of a new product that will be introduced next month that is geared to the biomed.So, I wouldn�t tell you about this technique if I didn�t have a piece of equipment that would measure MTF.
