 Good day everybody. Dr. Sanjay Sanyal, professor of department chair. So this is going to be a demonstration of a three-piece artificial pinot emplant, which was an external urinal sphincter. This is a sphincter ever. I'm standing on the left side I'm doing the narration as well as holding the camera. So first let's take a look at the parts of the three-piece pinot emplant We can see this structure here This is the reservoir. We have purposely collapsed the reservoir because we are going to show its function a little later This reservoir was implanted at the lower part of the left rectus abdominis muscle. This is the left rectus abdominis muscle This is the right rectus abdominis muscle And then we can see that going out through the rectus sheath is this tube here with its corrugations This tube I'm tracing it. It was tunnel in the subcutaneous tissue of the pubic region And it came to the left side and it was pushed inside the left scrotum and Inside the left scrotum we can see this structure here This is the pump below and The valve above and coming out from the valve. We can see this other tube coming out And I'm tracing it and this is the tube which then goes to the third piece That is to the external urinal sphincter itself And this was wrapped around the bulb of the corpus pangeosum. This is the penis We have cut the corpora cavernosa and this is the corpus pangeosum. So therefore we can see that it was wrapped around the bulb of Corpus pangeosum. So therefore this is the three piece panel implant which actually is an external urinal sphincter to summarize This is the reservoir This is the pump and the valve and this is the actual implant external urinal sphincter This is the diagrammatic representation of the sphincter to show three parts of the implant Now I shall demonstrate the mechanism of action because a little bit of the mechanism of action is still retained We know that this is the left scrotum because this is the left sphormatic code and that is the right sphormatic code I'm going to pull out this from the scrotal sac where it was implanted. I'm going to press on the pump So please take a good look when I press on the pump And if you notice when I press on the pump the corpus pangeosum was moving and The external urinal sphincter is contracting The one which was wrapped around the corpus pangeosum. So this was how it was working So when I press on the pump Which the person can do himself during life when it was inside the scrotum It caused external urinal sphincter wrapped around the corpus pangeosum to expand because it's wrapped around and it acts like a sphincter When he wants to release he will press the valve and when I press the valve if you notice It will cause inflation of this reservoir. If you watch carefully Reservoirs inflating when he wants to release the sphincter He will press on this valve and he will drain the fluid away from the sphincter there and push the fluid back into the reservoir So this is how the mechanism of action of the three-piece phenyl implant now I'm going to pull out the three-piece phenyl implant this corpus pangeosum I've taken it out from the corpus pangeosum and we can see that it is double lumen structure This is wrapped around the corpus pangeosum. We squeeze on this pump here. This inflates. So watch carefully We can see it inflating When I squeeze on this It inflates and when I squeeze on the valve it deflates and the reservoir inflates External urinal sphincter works and this is how it was implanted. Thank you very much for watching Dr. Sanjay Sanyal signing out. If you have any questions or comments, please put them in the comment section below. Have a nice day
