You can use this knot to close and secure bags, tie something to a pole or branch. ![]() This knot has diverse practical applications as it is very stable and can be. In contrast to the double throw of the Surgical Half knot, the Constrictor Knot tightens more readily and is less prone to slip. This quick lesson from the ITS Tactical YouTube channel explains how to tie the hard-binding constrictor knot. A type of knot or hitch often used to fasten the neck of a sack of grain or flour. This particular technique necessitates dividing the vessel prior to positioning and tightening the ligature – unacceptable in some circumstances.Īdvantages: The additional pass around the vessel enhances the constriction effect. To close the openings of sacks or bags tightly. Prior to cutting a vessel, a Constrictor Knot can be slipped over each of two forceps, which can then both be clamped onto the vessel, and the vessel cut between them.ĭisadvantages: The Constrictor Knot requires two passes around the vessel or pedicle and the knot itself requires learning.

Once perfected, it is by far the quickest method. Examples of binding knots include the Millers knot, the modified Millers knot or strangle knot and the constrictor knot. Description The constrictor knot is one of the most effective binding knots. More commonly the two sides of the first loop benefit from a little push. In some materials, the knot actually forms just by twisting the ends. Technique: In this animation, the Constrictor Knot is formed using the Twisting Method. Our paper has generated interest and, as a result, the Royal College of Surgeons has kindly made it Available On Line. For our research we used a modification of his test bench to confirm that the Constrictor Knot is the most secure ligature by a large margin because of its ability to stay tight 1. Research on the Constrictor Knot: Howard Taylor, a veterinary surgeon in Salisbury, England pioneered the use of the Constrictor Knot to ligate the uterine pedicle in a canine hysterectomy and prefers his Instrument Technique. Sliding the Constrictor Down the Forceps (shown here).Options: Four ways of tying it in surgery are compared: This Sliding Technique is one way to facilitate tying it. * The constrictor is also referred to as a Miller’s Knot in that it was used to tie the tops of bags of flour.Uses: The Constrictor Knot ( ABOK # 1188, p 216.) is uniquely suitable for use as a surgical ligature: it has superior binding properties, tightening smoothly and holding tight.

To use interchangeably with a clove hitch, except once the constrictor is pulled tight, it is quite hard to untie.Like a clove hitch, the constrictor can be tied using the end of the rope (see figures 19 and 20) or by forming a twisted loop and slipping it over a spar (see figures 21, 22, and 23). The constructor is based on the clove hitch, except that it has an extra half-knot that provides an extra hold when the knot is pulled tight. In the days when black powder was used for blasting in mining operations, this was the knot that was tied around the top of the bag containing the black powder to hold the fuse in securely hence, it’s other common name, the Bag Knot. i really like the centered, secure trapped alignment/nip of especially the BE in Constrictor/Bag, that is fairly unique here but seen in another EXCELLENT knot.
