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 Greek physician Heraklas in a monograph on surgical knots and 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 The constrictor knot is the knot ...

Diagrams Illustrating Various Surgical Stitches And Knots
A diagram is a symbolic Depiction, representation of information using Visualization (graphics), visualization techniques. Diagrams have been used since prehistoric times on Cave painting, walls of caves, but became more prevalent during the Age of Enlightenment, Enlightenment. Sometimes, the technique uses a Three-dimensional space, three-dimensional visualization which is then graphical projection, projected onto a two-dimensional surface. The word ''graphics, graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphics, graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links.

Strangle Knot
The strangle knot is a simple binding knot. Similar to the constrictor knot, it also features an overhand knot under a riding turn. A visible difference is that the ends emerge at the outside edges, rather than between the turns as for a constrictor. This knot is a rearranged double overhand knot and makes up each half of the double fisherman's knot. See also *List of binding knots *List of knots *Clove hitch The clove hitch is a type of knot. Along with the bowline and the sheet bend, it is often considered one of the most important knots. A clove hitch is two successive half-hitches around an object.

List Of Knots
This list of knots includes many alternative names for common knots and lashings. Knot names have evolved over time, and there are many conflicting or confusing naming issues. The overhand knot, for example, is also known as the thumb knot. The figure-eight knot is also known as the Savoy knot or the Flemish knot. A * Adjustable Bend – can be easily lengthened or shortened * Adjustable Grip Hitch – a simple hitch which may easily be shifted up and down the rope while slack *Albright Special – used to tie two different diameters of line together, for instance to tie monofilament to braid *Alpine Butterfly (also known as Butterfly Loop) – a static loop mostly used by mountain climbers and rappellers for securing a carabiner to static rope. * Alternate Ring Hitching – covering a ring in hitching can prevent damage * Anchor Bend – attaching a rope to a ring or similar termination *Angler's Loop – knot which forms a fixed loop.

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 and seizing are binding knots, but are more complex since they contain many turns, like a lashing. This is a list of binding knots. * Boa knot *Bottle sling * Constrictor knot * Corned beef knot *Granny knot *Ground-line hitch *Miller's knot *Packer's knot *Reef knot * Strangle knot *Surgeon's knot *Thief knot *Jamming knot *Sheet bend *Sheepshank *Common whipping See also *List of bend knots *List of knots *Rope splicing Rope splicing in ropework is the forming of a semi-permanent joint between two ropes or two parts of the same rope by partly untwisting and then interweaving the ...

List Of Bend Knots
This is a list of bends. A bend is a knot used to join two lengths of rope. They are used in a variety of situations, including climbing, sailing, and securing loads. Bend knots are classified based on their ability to be tightened or released, their resistance to slipping, and their strength. Some common types of bend knots include the double fisherman's knot, the double overhand knot, and the double figure-eight knot. Bend knots are important because they 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 knot for the specific task at hand, as some bend knots may be stronger or more secure than others. The sheet bend is the classic bend. Misuse of reef knot as a bend The common 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 under sufficient tension. For this reason, the reef k ...

Quiet Eye
Definition Quiet eye (QE) is a period of extended visual attention that helps in optimizing the control and execution of motor skills, particularly in high-pressure situations or tasks that require precise movements. In simple terms, it is a technique reported to improve outcomes in various tasks requiring human visual attention. It has been the subject of several articles in journalistic periodicals, and of scientific studies that evaluate it in relation to activities such as sports and surgical training. A meta-analysis conducted twenty years after the initial QE study was published has identified the QE as one of three gaze behaviours that reliably distinguish professionals from non-experts. Experts had a QE duration on average that was roughly 62% longer than that of non-experts. Moreover, there were 580 QE records discovered in all, demonstrating the region's tremendous expansion in recent years. History Professor Joan Vickers is credited as the originator of quiet eye theo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surgical Suture
A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of 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 different tissues, as well as the memory of the threa ...

Hemostasis
In biology, hemostasis or haemostasis is a process to prevent and stop bleeding, meaning to keep blood within a damaged blood vessel (the opposite of hemostasis is hemorrhage). It is the first stage of wound healing. This involves coagulation, which changes blood from a liquid to a gel. Intact blood vessels are central to moderating blood's tendency to form clots. The endothelial cells of intact vessels prevent blood clotting with a heparin-like molecule and thrombomodulin, and prevent platelet aggregation with nitric oxide and prostacyclin. When endothelium of a blood vessel is damaged, the endothelial cells stop secretion of coagulation and aggregation inhibitors and instead secrete von Willebrand factor, which initiate the maintenance of hemostasis after injury. Hemostasis involves three major steps: * vasoconstriction * temporary blockage of a hole in a damaged blood vessel by a platelet plug * blood coagulation (formation of fibrin clots) These processes seal the injury or ho ...

Hemoclip
An endoclip is a metallic mechanical device used in endoscopy in order to close two mucosal surfaces without the need for surgery and suturing. Its function is similar to a suture in gross surgical applications, as it is used to join together two disjointed surfaces, but, can be applied through the channel of an endoscope under direct visualization. Endoclips have found use in treating gastrointestinal bleeding (both in the upper and lower GI tract), in preventing bleeding after therapeutic procedures such as polypectomy, and in closing gastrointestinal perforations. Many forms of endoclips exist of different shapes and sizes, including two and three prong devices, which can be administered using single use and reloadable systems, and may or may not open and close to facilitate placement. Structure and function The endoclip was first described by Hayashi and Kudoh in 1975, and was termed the "staunch clip". Initial attempts to incorporate the clip into applications in end ...

Von Leffern Knot
The term ''von'' () is used in German language surnames either as a nobiliary particle indicating a noble patrilineality, or as a simple Preposition and postposition, preposition used by commoners that means ''of'' or ''from''. Nobility directories like the ''Almanach de Gotha'' often abbreviate the noble term ''von'' to ''v.'' In medieval or early modern names, the ''von'' particle was at times added to commoners' names; thus, ''Hans von Duisburg'' meant "Hans from [the city of] Duisburg". This meaning is preserved in Swiss toponymic surnames and in the Dutch language, Dutch or Afrikaans ''Van (Dutch), van'', which is a cognate of ''von'' but does not indicate nobility. Usage Germany and Austria The abolition of the Monarchy, monarchies in Germany and Austria in 1919 meant that neither state has a privileged nobility, and both have exclusively republican governments. In Germany, this means that legally ''von'' simply became an ordinary part of the surnames of the people w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knot Pusher
A knot is an intentional complication in cordage which may be practical or decorative, or both. Practical knots are classified by function, including hitches, bends, loop knots, and splices: a ''hitch'' fastens a rope to another object; a ''bend'' fastens two ends of a rope to each another; a ''loop knot'' is any knot creating a loop; and ''splice'' denotes any multi-strand knot, including bends and loops. A knot may also refer, in the strictest sense, to a stopper or knob at the end of a rope to keep that end from slipping through a grommet or eye. Knots have excited interest since ancient times for their practical uses, as well as their topological intricacy, studied in the area of mathematics known as knot theory. History Knots and knotting have been used and studied throughout history. For example, Chinese knotting is a decorative handicraft art that began as a form of Chinese folk art in the Tang and Song Dynasty (960–1279 AD) in China, later popularized in t ...
