this is what the really efficient surgeons do. The index-finger technique will be used here to perform the first throw. if you sew with your right hand, you should tie with your left. Background Training of basic laparoscopic psychomotor skills improves both acquisition and retention of more advanced laparoscopic tasks, such as laparoscopic intra-corporeal knot tying (LICK). 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. (b) The strands of suture material need to intertwine in alternate directions with each throw in order for the knot to square. (a) Adhere to the proper knot tying procedure strictly. Follow these general principles for tying a knot.
SURGERY KNOT TYING 2 HAND SKIN
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. Entering and exiting the skin at the same level. bond, obligation shoelace necktie, cravat, four in hand or bow tie fastening, ligature draw, tied score, dead heat. 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. While preclinical studies confirmed the speed of COR-KNOT use, no clinical studies have quantitatively compared the speed of suture fixation delivered by the COR-KNOT device with the speed of conventional hand-tied knots. Hand tying of knots can be accomplished by either the two-hand or one-hand technique. The COR-KNOT technology (LSI SOLUTIONS, Victor, New York USA) was developed to replace suture tying with a faster procedure during surgery.
