So today we're going to learn how to do a to hand tie for this. We'll need are not tying board our practice string or you can use suture o silk ties work best and gloves are optional, but I highly recommend them. It's always best to practice the skill the same way you're going to execute it in the operating room. Now, you can use this skill to secure any not and most attendings and residents will actually want you to show mastery of this not first before moving on to other ties such as a one handed tie to start, we'll put our not tying board in front of us and we'll thread our practice string behind the side that has the penrose drain. I'm going to put my blue side of my string on the left side and the white side of my string on my right side. Now, the key to making this knot is making L's and sees with our hands. And what I mean by that is for the beginning part of this, not, we're going to make two L's with both our hands. And when we move on to the second part, we're going to make to seize with both our hands. So what that looks like is if we pick up our string, making two owls with both of our hands are string is going to be draped as such around our index finger and this is how we're going to start or not. Now, if you're right handed, your right hand is going to be the post and your left hand is going to be the hand that moves first if you're left handed. No worries, we're going to make a whole set of videos just to demonstrate that as well. To start what we'll do is we'll take the string that's in our left hand and we'll cross it over our right index finger to make an X from here, we're going to pinch our thumb and index finger together and we're going to rotate our fingers. So our thumb goes through the loop and our index finger comes out on top. Once again, we'll rotate our fingers. So now our thumb is on the bottom and our index finger is on the top from here. We can unpinch our thumb and our next finger and we can use our left hand to drape the blue end of our string, laying it over top our thumb. Well, once again, pinch our thumb and our index finger together and we'll rotate our fingers back to where they started this time bringing the blue side of the string with us. Now, if you notice this isn't exactly a square. Not if we didn't cross our strings in the beginning. What we'll have to do is cross our hands here. So I'll cross my hands to lay down a nice square. Not now, this is just one half of are not in order to continue throwing square knots. What we'll have to do is switch to making the sees that we talked about before. So to do this, you'll pick up the same side of the string and the same hand that you had before. So for me, the blue side is in my left hand and the white side is in my right hand. But instead of making else this time, we'll make sees with the string draped around our thumb as such. Once again, if we're throwing right handed ties, what we'll do is we'll take our left hand and we'll cross it over the string that's on our right thumb to make an X very similar to what we did before. Well, pinch our thumb and our index finger together and well, once again, rotate them through the not. So now our thumb is on top and our index finger is on the bottom. Well, unpinch are index finger and our thumb and using our left hand will take the blue string and will drape it over our index finger. Well, once again, pinch are index finger and our thumb with the blue string in between them. And we'll rotate our hands back through bringing the blue end of the string with us. Now, since we crossed our hands last time, we don't eat across our hands this time to go ahead and throw down a nice square. Not to continue, you'll move back to making your elves with both of your hands to throw your next. Not and then back to your sees for the not after that, alternating back and forth your Alice and sees for each. Not so that way, then you'll always throw square knots and that is how you do a two handed not tie.
