Chapters Transcript Video Philips CVX-300 Laser System in-service Learn about Laser safety, how to operate the CVX-300, it’s parts and the calibration technique. Hello. My name is Davis. I worked with Philips I G T. D. As a field service engineer on the CB X 300 laser. And I'm going to be demonstrating today the in service portion and functionality of the CB X 300 laser. The first thing I want to discuss is laser safety. Laser safety is very important because this is a Class four laser which is the highest level for a potential I hazard. And you are going to want to have these laser safety signs placed it on every door and every entrance to your controlled environment. It is very important to maintain a controlled environment when using this laser system. Mm hmm. This laser system is going to have the word danger. The universal symbol for a laser visible. Invisible laser radiation avoid skin or eye exposure or direct scattered radiation eye protection required. This is a 308 nanometer which is on the U. V spectrum eczema laser Class four. There's also a 670 nanometer diode laser which is 38 which is less dangerous. It's on this. It's for the laser pointer. With regards to laser safety. You're gonna want to utilize the laser safety goggles that are assigned to this laser. You will see the name spectrum ethics here but also you can use any other number of laser safety goggles as long as they are optical density six or higher. In this case for the 1 92 3 80 nanometer wavelengths. This is rated at optical density greater than nine. So these are actually really good for protection of the U. V. Laser light that comes out of the C. V. X. 300 laser and you can actually adjust the legs here to fit your ear size and they fit quite nicely even over large glasses like these. The next thing I want to discuss is the moving of the CTX 300 laser. Obviously it's very heavy as you can see this rear handle, you can push it from this rear area if you're going in a straight line, if you want to be making some turns, you're gonna definitely want to use inserts here because the swivel wheels are on this side. There is a foot brake down here that sometimes is harder on some days and some systems and others lift it up like soda release and then you can turn it quite easily from this side. It's very difficult and you must not try to turn it from this side because you end up having a tough time getting it around corners. Another thing you want to be careful of is when you're you're going pushing it, you want to go over smooth surfaces, you don't want to jar it, bump it. It can knock the laser system out of alignment, which could result in a failed calibration of your fibers. This is the rear portion of the laser where the power cord is located. It's wound up around this black rear door, we're gonna unwind it And this is a special outlet. It's a 208 twist lock outlet. It's going to be labeled as to 50 volts A C 30 amps. This goes in like so mhm There's a little safety lock so that you won't be able to pull it out. Also, you're going to ensure that your circuit breaker is pushed towards the one zero is off, one is on and then now you're laser system is ready to power on. There's also an emergency stop here. This is for any type of emergency. You want to turn off the laser right away. This is where you, you press the button and you will hear that audible tone. That means the emergency stop is engaged. Un engage it, You twist it to the right like this and it turns off and now you're ready to power on your laser system. In order to power on the laser system, you need to turn it on with the key, there's two keys that come with every later system you will see that. The position it starts in is zero And you turn it over a quarter turn to the right to turn it on. You're gonna get all the lights turned on minus that one. That is the software 3.818. That's the latest and most current software and it's testing. Yeah mm hmm mm hmm. From here, you will see a power error light illuminate its testing the bean block. That is not an actual error is just testing the functionality of the laser system. The laser will now enter warm up mode for five minutes. This is very important to the laser operation because this is a high voltage powered laser. These high voltage components do need that five minute warmup period in order to truly function the way they're supposed to during the setup of the system. You see that there is the foot switch light is illuminated and the fiber light, is it? These are the needs of the machine. We're gonna go with the foot switch plug in first. There's a foot switch storage door located right here in the front of the system. This is typically where you will see the laser foot switch stored. This is a metal braided shielded cable and you're gonna want to take care good care of this that it doesn't fall and it's always in good condition and untangled, poured this foot switch plugs in in the rear part of the lady. And I'm going to demonstrate how to plug it in the I'm here at the rear of the laser where the foot switch plugs in. You're going to see the foot switch word there and a four pin connector. You're also gonna see this red dot On the 12 o'clock of the foot switch connection site and you're gonna plug it in like so it's a locking plug. Once it's locked, it will not come off unless you pull it off like this. You hear that tone, that means that the foot switch lite is now illuminated and what we should see on the display is after you plug in the foot switch and lock it all the way that the foot switch light will turn off on the display here, we're back at the front of the laser, you can see that the foot switch lite is now turned off but we do have the fiber light is still illuminated. So we're going to plug in our test fiber or 2.5 reference catheter. We're gonna plug it into the the system, it only goes in one way, there's a little pin code here and it will Turn off the laser fiber light and it will give you the automatic settings for the fiber calibration. In this case it's 45 25. Our warm up is now complete. As you can see the warmup light is not on and it is no longer counting down. So now we are ready to test the laser out. Okay, now, once you have the laser catheter plugged in, you can go ahead and raise this post here. This is sort of a guide, You can place the the laser catheter to help keep it out of the way or to sort of aim it towards the operator's table so we're gonna position it like so and now we've turned everything off. The foot switch light is off, the fiber light is off, there's no other warnings or cautions here. The warm up is now complete as you can see the warmup light is off. And now we're going to proceed with the calibration of the test catheter, the 2.5 reference catheter. So this is the 2.5 reference catheter. You will see it says here, not for human use, obviously it's very short, it won't do anything, there's no over the wire action on it. You will see how it plugs in, plugs in with this pin code and it only goes in one way. The purpose of this fiber is uh simply a test fiber to check the functionality of the laser prior to opening a sterile fiber. The calibrate light is on. So we are going ahead. I'm going to make sure everyone's wearing their laser safety glasses and go ahead and press the calibrate button like. So you will hear the laser sort of turn itself onto the ready mode. And now you're going to follow the instructions to aim the fiber, aiming the fiber means that you're going to position it here. You can see the laser pointer here, you're gonna position it here using this uh guide as a stick. This sticker as a guide and you're going to aim it right at the center and perpendicular of the calibration. You will go ahead and press the foot switch. Yeah. And you're going to hold the foot switch until you see, cal okay illuminated, The laser system will place itself back into standby mode and then now you are actually ready to laze in the ready mode like. So yeah you can place the laser back in standby after every fiber is pork. It's going to re illuminate this fiber light and re illuminate the calibration like this is there to ensure that every new fiber that is placed into the laser system is calibrated once again. Mhm. Now the fiber light is off to calibrate light stays illuminated, you have to recalibrate the fiber so once you have your laser positioned in place you may or may not want to use the foot brake. The foot brake is located here in the front of the laser and it's simply pushed down and to unlock it. Now that is completely locked. The laser will not move from there if you want to unlock it, you get underneath it and then you lift like so some of these may be a little stiff and you may have to reach down with your hand to pull it up. Once the position has decided that he no longer needs the laser, you can go ahead and turn off the laser system like this. Mhm. Once the laser system is off you can commence to removing the fiber like so you can lower this post like this, there's a little slide once you slide it over this can go down and please close the dust cover because that protects the optics to disconnect the foot switch, you're gonna need to pull it from this centerpiece in order to unlock it. That's how it unlocks. You can wind up the court and place it back in the storage door. Of course after cleaning it, it's very important to maintain this chord clean. Once you have a nice clean foot switch you can go ahead and open this front door and store it. Okay. In order to unplug the laser, you have to remember that. This is a twist lock cord. Do not force it out because you can damage the outlet, grab it from this portion here, do that slight twist left and then you can pull it out and commenced to wrapping the cord on the rear of the laser like so. Okay, okay. Published February 25, 2022 Created by
