Medical knot on a fishing line. Learning to tie a surgical knot. Potential Uses

One of the stages of assembling feeder equipment is the creation of a single structure consisting of a feeder for complementary feeding and a leash with hooks. After which the resulting structure must be attached to the main line. The key to successful, enjoyable fishing is functional gear, so the methods of connecting all these elements should be simple and reliable. One of the optimal solutions in this matter is the use of a surgical unit.

Scope of application

Fishing gear is connected using synthetic fishing lines or cords. At the same time, their ends must be well fixed. In the design of the tackle, knots are used to fasten the leash, feeders, fasteners and any joints of parts of the fishing line with each other.

Feeder tackle requires the use of the following components:

• connecting the main line with leashes or hooks;
• for attaching fishing line to the reel;
• surgical (both knot and loop).

In the process of using feeders, conventional nodes perform, to put it mildly, unsatisfactorily. In case of heavy loads, they cannot always cope with them, so it would be more practical to tie surgical knots for the feeder. According to statistics, gear that uses surgical knots fails in one case out of thirty, which is almost three times less likely than using conventional bonding methods.

An important advantage of this joining method is the ability to connect fishing lines of different diameters with it. For example, it can be used with both monofilament and carbon, as well as braided fishing line. And if the load capacity of the gear is exceeded by increasing the thickness of the fishing line, there will be no problems in tying the same leash to a new fishing line, even directly during fishing.

Attention! The fishing line for feeder fishing should have a thickness of 0.2 to 0.4 mm. In fact, it depends on the depth of the pond and the weight of the feeder.

Advantages and Disadvantages

There are two main advantages of using nodes of this type on the feeder:

1. Connection strength.
2. Possibility of cutting the ends of connected elements as short as possible, almost to the base.

When feeder fishing, very serious requirements are set for the reliability and strength of all connections of the gear, since fishing involves not only hooks and a leash, but also a heavy feeder.

In addition, if the gear breaks during fishing, it is with the help of a surgical unit that you can quickly repair the gear. Despite the relative simplicity of the circuit, the reliability of such a connection is one of the highest among fishing units.

Externally, the surgical unit diagram is similar to the double running one, since it is implemented using two turns. The differences in their patterns are that for knitting a surgical knot it is permissible to use two fishing lines of different thicknesses.

A surgical loop can be used to attach a leash or feeder to the main line. It is believed that using a loop will give the bait a natural movement.

The main disadvantage of this connection is its large size, in particular its width. We should not forget that when tying it, you may encounter a significant bend and slope of the main line at an angle.

Installation features

The weaving sequence is as follows:
1. First, you need to put together the fishing line and what will be tied to it (leash, fishing line from the feeder, torn part, etc.)

2. You need to form a loop from the lines folded together and thread both ends through it once.

3.The ends are re-threaded through the loop to create a surgical knot.

4.After this, the resulting loop should be moistened with water and tightened tightly. Excess ends must be trimmed.

In some cases, not only a double, but also a triple knot of a similar shape can be used (the ends are threaded through the loop not twice, but three times). However, such a design on a fishing line is very cumbersome and inconvenient. It is used exclusively for thick lines, or for extremely powerful gear for catching large fish.

The weaving of the loop has slight differences from the given sequence:

• not two different fishing lines are taken, but one is folded in half;
• the fold is threaded through the loop once, not twice.

The loop is made by pulling the remainder of the fishing line into the knot ring.

This method of tying allows you to arbitrarily change the size of the loop. This is done by moving the tying point up and down along the doubled fishing line, as long as its length is sufficient.

Once the size of the loop has been determined and the tying point has been moved to the desired distance, you should wet the fishing line with water and tighten the loop.

Application with different gear

There are several equipment used for feeder fishing. The most popular are the following:

• symmetrical loop;
• asymmetrical loop;

The purpose and functions of these accessories are the same, but they have serious differences in the design and methods of fastening. All three schemes have connections that are preferably made using a surgical knot or loop. Let's look at them in detail.

Symmetrical loop

This equipment has high sensitivity, as it is used for catching crucian carp in standing waters. On it, a swivel with a carabiner is attached to a double piece of fishing line after its ends are twisted. It is at this attachment point, approximately 10 cm from the end, that the knot should be made.

Asymmetrical loop

It is usually used for catching small fish on a feeder, so it is quite sensitive. Although, this is not mandatory. The main point in the design of the tackle is that the feeder with complementary food goes slightly to the side of the leash with bait.

The design of such equipment itself uses monofilament, so the use of the unit in question in this case is the most rational.

The design of the equipment with an asymmetrical loop allows you to use a wide variety of devices for feeder fishing, changing them directly during fishing, while using a surgical knot or loop to connect them.

Gardner rig

Used for fishing in reservoirs with strong currents. The knot is used in all main connection points: at the end of the equipment, to connect the feeder with bait and for the leash.

The surgeon's knot is one of the simplest joints used in fishing. It is easy to tie, and at the same time, the connection with its help is highly reliable. An important advantage of the knot is its ability to connect fishing lines of different thicknesses, which is used in feeder equipment.

All nodes, used in surgical practice, double (sometimes triple). The first knot is the main one and should be tightened as much as possible. The second knot secures the first one, that is, it prevents it from untying or loosening. The third knot is applied when using catgut and synthetic ligatures for greater strength, since these threads are very elastic and their surface is slippery.

In surgery there are many types of nodes, but are considered basic simple, nautical And surgeons ical (Fig. 2.16).

We present classic way to tie a simple knot(Fig. 2.17).

The ends of the thread are grabbed by hand(see Fig. 2.17; 1).

When forming the first (main) node first, the position of the ends of the threads in the hands is changed - the left end of the ligature is taken in the right hand, and the right end in the left, thus forming a cross of threads (the thread in the left hand is placed on top of the thread fixed with the right hand) (see Fig. 2.17; 2). This cross is fixed between the II and I fingers of the left hand (II finger on top, the cross of threads is pressed to the base of its nail phalanx on the palmar surface, see Fig. 2.17; 3).

I and II fingers of the right hand fix the end of the thread, pull it and bring it under the protruding end of the nail phalanx of the second finger of the left hand. The gap between the threads can be widened with the third finger of the right hand (see Fig. 2.17; 4). Next, by turning the left hand with a nodding movement of the second finger, the end of the thread is drawn into the slot (see Fig. 2.17; 5).

The knot is tightened(see Fig. 2.17; 6).

For forming a simple knot the second (fixing) knot is tied in the same way as the first, but the second stage - repositioning the ends of the ligatures - is not performed.

Simple knot not strong enough, it slips and can be stretched by pulling one end of the ligature from the loops of the other.

When forming a sea node at the second stage, repeat all the steps from the beginning: grabbing the ends of the thread, shifting the ends of the thread from hand to hand (cross), passing one of the ends of the thread into the slot, tightening.

Surgical The knot differs from a simple one in that when tying the first (main) knot, the right end of the ligature is wrapped twice around the left end. When tightened, such a first knot is more firmly fixed as a result of friction and does not relax before tying the second one. This is the most reliable knot, but more cumbersome compared to a marine or simple one.

To successfully tie a knot the ends of the threads must be constantly taut.

Choosing a node type depends on the stage of the operation and the suture material used.

In addition to what is described classic way of tying a knot, in surgical practice there are many other ways to knit knots. However, as a result of any manipulations, one of the three types of nodes described above should be obtained.

Training video of the technique of tying a simple knot in surgery

For proper installation of the feeder, it is necessary to firmly fix the feeder and the leash into one structure; for this, a variety of connecting nodes are used, one of the most popular among professionals is the surgical loop node. For the catchability of the gear and the productivity of fishing, you need to be able to correctly knit a surgical loop, know all the nuances and weaknesses of this fastening method and practice a little. So, how to tie it correctly, where is it used and why do beginners often make the same mistake, which causes failures and the loss of all the equipment along with the “trophy fish”?

Often, for such loops, synthetic cords and fishing lines are used that have high strength values, while the ends of the gear are tightly fixed so that no problems arise. A surgical loop is knitted when it is necessary to attach a leash or feeder, as well as in some special cases when the ends of the fishing line are connected. Sometimes it can save you even if you do not have a spare main line, and the length does not allow you to use the remaining piece.

1. Assembly for attaching to a reel.
2. Surgical node.

But still, not a single knot can compare with a surgical loop when attaching a feeder, since most of the parts simply cannot withstand heavy loads, while the loop can withstand even sharp jerks of massive fish, which will help hook and pull out a trophy specimen, which, in otherwise, it would break loose and float away along with all your equipment.

However, there are also cases when even a surgical knot cannot withstand the load, but this is due either to poor implementation or to debris at the bottom of the reservoir to which the tackle clings.

The name itself confuses many people not involved in fishing, but the assumption that the knot is used by surgeons themselves is actually correct, only in medical practice it is the other way around - it is called “marine”. The main advantage of fasteners in both areas is that strong adhesion due to the frictional force in the loop allows you to get rid of “shoots” under the base, which is necessary not only for doctors, but also for fishermen, especially for the mobility of gear. But with a heavy feeder in addition to a hook and weight, when you fish with feeders, reliability becomes of paramount importance, especially when the tackle is attached between two different types of fishing line.

1. For feeders, fluorocarbonate or braid is often used.
2. For comfortable and long casts, monofilament fishing line is better suited.

The clear advantage of the surgical loop is its strong grip and the ability to shorten the protruding ends of the knot, which minimizes the possibility of snagging or untying the knot. But when using a feeder, the strength of the main and auxiliary fishing lines is very important, and not only the materials from which they are made play an important role, but also the methods of connecting the equipment to the fishing rod. After all, the fishing rod is loaded not only by weights and a hook, but also by a massive feeder, of which sometimes up to several pieces are attached.

In order for everything to work out correctly, strictly follow the instructions, namely:

1. Place the leash and main line together.
2. Form a loop from the resulting structure and pass the ends of both lines through it.
3. Repeat the previous action.
4. Wet the resulting knot with water and tighten it, thereby checking the connection for strength and further strengthening it.
5. Trim the remains to fit the base.

After this, you will have a strong connection that can survive the most massive predators and stormy bodies of water.

The main thing is to practice before using it and don’t be afraid to tighten the knot tighter, it’s not a “bow”, and you obviously don’t have to untie it.

A surgical feeder knot will help the angler while fishing. It is quite simple, universal, and although often not the best choice, you can master and apply it quickly enough. Used for tying two fishing lines, tying a shock leader and tying loops.

This knot, as the name suggests, was first used in medicine by surgeons. It is used to tie two suture threads together during surgery, as well as to secure the thread at the beginning of the suture. This knot must be simple and very reliable, since if the seam comes apart, the consequences can be very tragic. It is used at the beginning and end of a seam, as well as for tying two threads. Many medical schools recommend that surgeons, especially beginners, use this unit exclusively.

How to tie two threads with a simple surgical knot

The easiest way to master this knot is with two ropes. When you begin to understand what and how to do, it’s easier to switch to fishing line, braided cord or other materials. The knot used for two threads can be easily transferred to loops. The knitting sequence is as follows:

• Take two ends of the ropes, one in the left hand, the other in the right
• Two ropes are twisted together to form something like a spiral. For a high-quality assembly you need to make at least four turns.
• Then the ends of the ropes are placed on top of each other to form a loop between the spiral and the ends.
• One of the ends is passed into this loop. It is better to do this twice, but the knot on the ropes will hold even after one pass.
• By pulling the ends, the knot is tightened.

The result should be a fairly strong and simple connection.

How to fix the thread at the base of a surgical suture

Of course, this has an indirect relation to fishing. However, in order to tie a swivel at the end of a fishing line, and for other purposes, it is quite suitable. A description will be given of how to make a fixation using your hands. Experienced surgeons do everything using available tools - clamps, tweezers. This is one of the main advantages of such a knot - the ability to make it using a tool, but more on that later. The use of the instrument saves the surgeon’s fingers from pricks, which saves the doctor from infections when performing operations on patients, for example, HIV or tuberculosis, as well as minimizing contact with large surfaces such as gloves to reduce the likelihood of microbes from the outside being introduced into the treated wound.

• At the beginning of the suture, the surgeon threads the needle through the edges of the wound.
• He then makes a loop, which he crosses on his finger, placing one end of the thread over the other.
• After this, one end of the thread is passed through the loop several times.
• A loop is formed, and it tightens, tightening the edges of the wound.
• Then make another loop on top, passing one end of the thread into it and tightening it. It secures the knot from unraveling quite reliably.

Expert opinion

Federation of Fishing Sports of the Moscow Region

This type of knot is used by all surgeons, without exception, at least once in their practice.

Every practicing doctor knows how to tie a surgical knot of one kind or another. Also, people of other professions or hobbies, for example, fishermen, also know some techniques. They also often use a variety of surgical knots to weave nets. What types of nodules exist in medicine, and what properties should they have?

Requirements for surgical nodes

Surgeons don't like to use the word "strength" because it's not really the basic requirement for surgical nodules. After all, you can pull the threads very, very tightly, but this will injure the tissue and cause bleeding and suppuration. The correct node must be reliable, i.e. incapable of spontaneous divergence due to sliding of the threads. And only a professional and experienced doctor can correctly achieve such a balance.

If we list all the requirements applied to nodes in surgery, we will get a whole list:

1. easy to perform;
2. quick in education;
3. eliminates self-tightening in the process of changing the nature of the seam;
4. the properties of the nodule are preserved for the entire period of wound healing (it does not diverge, does not tear, does not move);
5. has a minimum volume (this especially applies to cosmetic seams);
6. the first loop is the strongest, each subsequent one is weaker;
7. The tightening technique corresponds to the chosen suture material.

The most difficult thing to work with is monofilament threads. They are slippery and smooth, they have a high “shape memory”. Therefore, knots made from such threads tend to return to their original state and straighten out. Braided suture material is the easiest to tighten because the knot is held in place by the interlocking of the threads.

A similar example can be given from everyday life: it is easy to tie a regular sewing thread, but a knot tied with the same force on a smooth elastic fishing line will quickly come undone.

Types and methods of tying surgical knots

The entire classification of methods for tightening and securing suture material is more correctly called knots in surgery. And the surgical (or marine) knot is one specific type that consists of two loops. The first (main) is double: one end, for example, the left one, wraps around the second, right, twice. This allows you to fix the knot more firmly. The second loop is single, but it is knitted in the other direction: the right thread around the left.

Curious! It turns out that doctors call such a knot a marine one. And sailors consider it a medical invention, which is why it is often called surgical.

In surgery, knots are knitted differently from laces: without crossing the ends of the threads and twisting them behind each other. There are special tying techniques that require dexterous finger manipulation. This is specially taught in medical schools. In practice, during operations, knots are often knitted with instruments. It is more convenient, faster and more reliable.

In addition to surgical knots in medicine, there are several other types of knots (not to be confused with the classification of sutures), differing in knitting technique and ultimate strength. They are used depending on the selected suture material and the organ being operated on.

• Female (ladies', women's, woman's). Elementary, from two simple loops.
• Academic. Complex, parallel and uniform. Consists of three loops. There is also double academic: this means that there is a double weave in each loop.
• Triple sea. The same as the surgical one, but with three loops, modifications of which can be combined (for example, one double and two simple, or outer double and the central simple, etc.).
• Parisian's knot. Sliding, blocked, consists of four loops that are formed in a specific way.

Experienced practicing surgeons do not keep in mind the names of the types of surgical nodes. During suturing, they automatically tie knots, focusing on the surgical field. Sensitivity also plays a role: if the doctor understands that the skin in this place is very stretched and the stitches may come apart, he adds another knot. If your hands feel that a double knot is enough, then the surgeon will not create a third loop.

A correctly tied surgical or other knot is a guarantee of maintaining the quality of the suture and the normal condition of the tissues. It’s these little things that make up the professional work of surgeons, who have been developing practice for years and decades in order to masterfully knit knots literally with their eyes closed.
