![]() Here holding the suture junction with the left hand is crucial.Ĭross the remaining suture of the short end from the loop with the help of the right hand’s index and middle finger and the knot to the base of the wound with the help of the index figure or thumb. Pull the Long End for tension and bring the short end onto the long end with the right hand’s index finger and middle finger and make ‘Figure Of 4’. Make sure to keep the short end above and the long end below for this technique. Hold the Long End between the thumb and ring finger with the index finger and middle finger straight and keep the left hand in the supine position. Hold the Short End between the thumb and ring finger with the index finger and middle finger straight and keep the right hand in the supine position. This is the most common surgical knot technique. Non-absorbable sutures should be left longer (around 10 mm) as they will require removal once the wound has healed, usually in 10–14 days. Minimal absorbable sutures should be left internally to reduce any tissue reactions that may occur. Knots may be hand tied or tied using instruments, but should not be over-tightened to avoid discomfort to the patient and to make the sutures easier to remove.Ībsorbable sutures may be cut fairly short, leaving a length of 2–3 mm. The knot consists of the loop, knot, and ears. The smaller the knot, the less tissue reaction, resulting in a more minimal scar. Knot security is defined by the quality of the surgical knot, the technique used, the type of suture used, the body tissue, the moisture content of the wound, and whether the infection is present. However, catgut is no longer used as it causes an inflammatory cellular reaction with the release of protease and may carry the risk of prion transmission if of bovine origin. Lister said that catgut soaked in chromic acid (a form of tanning) prevented early dissolution in body fluids and tissue, while Moynihan felt that chromic catgut was ideal as it could be sterilized, was non-irritant to tissues, kept its strength until its work was done and then disappeared. At the end of the nineteenth century, the textile industry provided major advancement, and both silk and catgut became popular as Suture Materials. In 1000bc, Indian surgeons were using horsehair, cotton, and leather sutures on the other hand, in Roman times, linen and silk and metal clips, called fibulae. Sutures are best made of soft thread, not too hard twisted that it may sit easier on the tissue, nor are too few nor too many of either of them to be put in. It was found that seven of Heraklas’ 16 knots and nooses were still applied surgically of late and that four of these have even been recently rediscovered for such applications. ![]() In the first century of our common era, the Greek physician Heraklas wrote a brief essay on how to tie 16 surgical knots and nooses for surgical and orthopedic purposes. Various surgical knot types and techniques are used in surgical practice and they form an important aspect of the basic surgical skillset for a surgeon. ![]() Surgical knots are a way of securely tying sutures over a specific tissue or while ligating blood vessels.
