The index-finger technique will be used here to perform the first throw. Either of them can be chosen to perform the first throw of the knot. The technique is composed of 2 basic steps called “index-finger” and “middle-finger” techniques. It is sometimes also referred to as a Hercules knot. The reef knot, or square knot, is an ancient and simple binding knot used to secure a suture or line around a tissue. The student of surgery should master first the construction of square type knots because knot security can usually be achieved with fewer throws than the granny-type knots. You can also go to the meat counter and ask about pigs feet - that works too. Surfaces - Get a chicken breast and suture that up. In all honesty, I instrument tied about 95 of the time though. The surgeons I was with wouldnt allow me to one-hand tie. When the surgeon attempts to shorten the resultant enlarged loop by advancing the knot, breakage of the suture may occur, requiring passage of another suture through the once punctured tissue. Knot tying - I would practice your instrument ties and two-hand tying the most. With the one-hand method, it is often difficult to maintain tension on the suture ends during the formation of the knot and slippage of the first or second throws will be encountered, especially by the inexperienced surgeon. An additional advantage of the two-hand tie is that the surgeon can apply continuous tension to the suture ends until a secure knot is formed. The two-hand technique of knot tying is easier to learn than the one hand. Each technique has distinct advantages as well as drawbacks. Hand tying of knots can be accomplished by either the two-hand or one-hand technique. Daily Calorie Calculator and Basal Metabolic Rate (BMR).
