Surgeon's Knot
The surgeon's knot is a surgical knot and is a simple modification to the reef knot. It adds an extra twist when tying the first throw, forming a double overhand knot. The additional turn provides more friction and can reduce loosening while the second half of the knot is tied. This knot is commonly used by surgeons in situations where it is important to maintain tension on a suture, giving it its name. Surgeon's knots are also used in fly fishing, in tying quilts, and for tying knots with twine; it is particularly useful in tying raw meat with butcher's twine, as the wet meat creates similar risks of loosening as surgery. Some sources categorize the surgeon's knot as a bend, since it can be effective as such. Like the reef knot, the surgeon's knot capsizes and fails if one of the working ends is pulled away from the standing end closest to it.

Reef Knot
The reef knot, or square knot, is an ancient and simple binding knot used to secure a rope or line around an object. It is sometimes also referred to as a Hercules knot or Heracles knot. The knot is formed by tying a left-handed overhand knot between two ends, instead of around one end, and then a right-handed overhand knot via the same procedure, or vice versa. A common mnemonic for this procedure is "right over left; left over right", which is often appended with the rhyming suffix "... makes a knot both tidy and tight". Two consecutive overhands tied as described above of the same handedness will make a granny knot. The working ends of the reef knot must emerge both at the top or both at the bottom, otherwise a thief knot results. The reef knot is not recommended for List of bend knots, tying two ropes together, because of the potential instability of the knot when not stabilized; something that has resulted in many deaths (see #Misuse as a bend, Misuse as a bend). ...

Double Overhand Knot
The double overhand knot or barrel knot is simply an extension of the regular overhand knot, made with one additional pass. The result is slightly larger and more difficult to untie. It forms the first part of the surgeon's knot and both sides of a double fisherman's knot. According to ''The Ashley Book of Knots'', "A double overhand knot tied in a cat-o'-nine-tails is termed a blood knot." When weighted, it can be difficult to untie, especially when wet. The strangle knot is a rearranged double overhand knot made around an object. It is sometimes used to secure items to posts. Instructions for tying # Tie an overhand knot at the end of a rope but do not tighten the knot down. # Pass the end of the line through the loop created by the first overhand knot. # Tighten the knot down while sliding it into place at the end of the line. Be sure to leave some tail sticking out from the end of the knot. Alternatively, the working end of the rope can be wrapped around the standing e ...

Surgical Knot
Surgical knots (ligatures) are the knots used to bind suture materials together while binding tissue in surgery. They are used in medical and veterinary settings. History Surgical knots have been used since the first century when they were described by Ancient Greek medicine, Greek physician Heraklas in a monograph on surgical knots and sling (implant), slings. In the past, the training of astronauts has included the tying of surgical knots. Application The effective tying of surgical knots is a critical skill for surgeons since if the knot does not stay intact, the consequences may be serious such as after pulmonary resection, laparoscopic cholecystectomy, and hysterectomy. The primary goal of surgical knot tying is to allow the capacity of a knot (or ligature) to be tightened and remain tight. Ligatures are locked and finished multiple overhand knots. Nevertheless, slipping sometimes happens before the addition of the final knot, particularly during an instrument tie. Knots ...

Surgery
Surgery is a medical specialty that uses manual and instrumental techniques to diagnose or treat pathological conditions (e.g., trauma, disease, injury, malignancy), to alter bodily functions (e.g., malabsorption created by bariatric surgery such as gastric bypass), to reconstruct or alter aesthetics and appearance (cosmetic surgery), or to remove unwanted tissue (biology), tissues (body fat, glands, scars or skin tags) or foreign bodies. The act of performing surgery may be called a surgical procedure or surgical operation, or simply "surgery" or "operation". In this context, the verb "operate" means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments, operating theater, surgical facility or surgical nurse. Most surgical procedures are performed by a pair of operators: a surgeon who is the main operator performing the surgery, and a surgical assistant who provides in-procedure manual assistance during surgery.

Surgical Suture
A surgical suture, also known as a stitch or stitches, is a medical device used to hold Tissue (biology), body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a Sewing needle, needle with an attached length of thread (yarn), thread. There are numerous types of suture which differ by needle shape and size as well as thread material and characteristics. Selection of surgical suture should be determined by the characteristics and location of the wound or the specific body tissues being approximated. In selecting the needle, thread, and suturing technique to use for a specific patient, a medical care provider must consider the tensile strength of the specific suture thread needed to efficiently hold the tissues together depending on the mechanical and shear forces acting on the wound as well as the thickness of the tissue being approximated. One must also consider the elasticity of the thread and ability to adapt to differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly Fishing
Fly fishing is an angling technique that uses an ultra-lightweight lure called an artificial fly, which typically mimics small invertebrates such as flying and aquatic insects to attract and catch fish. Because the mass of the fly lure is insufficient to overcome air resistance, it cannot be launched far using conventional gears and techniques, so specialized tackles are used instead and the casting techniques are significantly different from other forms of angling. It is also very common for the angler to wear waders, carry a hand net, and stand in the water when fishing. Fly fishing primarily targets predatory fish that have significant amount of very small-sized prey in their diet, and can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species (notably black bass). In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bend (knot)
A bend is a type of knot used to join two lengths of rope. Bends are used in a variety of situations, including climbing, sailing, and Load securing, securing loads. They are classified based on their ability to be tightened or Knot#Releasability, released, their resistance to Slipping (knot), slipping, and their Knot strength, strength. Some common types include the sheet bend, the double fisherman's knot, and the double figure-eight bend. Bends allow two ropes to be securely joined together, enabling the combined ropes to support weight or transmit force. It is important to choose the appropriate bend for the specific task at hand, as some may be stronger or more Knot#Security, secure than others. Misuse of reef knot as a bend The common reef knot, reef knot (square knot) is sometimes mistakenly tied as a bend. When used as a bend rather than a binding knot, the reef knot will Capsize (knot), capsize under sufficient tension. For this reason, the reef knot is insecure as a ...

List Of Knot Terminology
This page explains commonly used terms related to knots. B Bend A bend is a knot used to join two lengths of rope. Bight A bight is a slack part in the middle of a rope, usually a curve or loop. "Any slack part of a rope between the two ends, particularly when curved or looped." Knots that can be tied without access to either end of the rope are called knots ''in the bight''. To tie a knot ''with a bight'' is to double up the rope into a bight and then tie the knot using the double rope. Binding knot Binding knots are knots that either constrict a single object or hold two objects snugly together. Whippings, seizings and lashings serve a similar purpose to binding knots, but contain too many wraps to be properly called a knot. In binding knots, the ends of rope are either joined together or tucked under the turns of the knot. Bitter end Another term for the working end.

List Of Bend Knots
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

List Of Binding Knots
A binding knot is a knot that may be used to keep an object or multiple loose objects together, using a string or a rope that passes at least once around them. There are various binding knots, divided into two types. Friction knots are held in place by the friction between the windings of line. Knotted-ends knots are held in place by the two ends of the line being knotted together. Whipping knot, Whipping and seizing are binding knots, but are more complex since they contain many turns, like a lashing (ropework), lashing.
