1. What is ligation surgery? Meaning
Vigation surgery is a permanent contraceptive method. The surgery is performed on men and women who have no need for reproduction. As long as one of the spouses undergoes the ligation surgery, they can achieve permanent contraception. Methods. Ligation surgery is to tie or cut off the female fallopian tube or the male vas deferens by certain means, causing the body to be unable to ovulate or sperm, in order to achieve the effect of contraception.

The advantage of ligation is that it is once and for all and has high contraceptive efficiency.
3. Rope ligation method
1. Purpose:: Prevents slipping or temporarily prevents the rope from continuing to unravel when the end of the rope opens.
2. Disadvantages: It is difficult to untie the knot when it is too tight or wet.
3. Purpose: It can be used as a temporary or simple stop and braking point on a rope.
4. Features: Even if both ends are pulled tightly, it can still be easilyUntie it.
5. Purpose: tie the two ends of the same rope together. It is suitable for connecting ropes of the same thickness and material; but it is not suitable for thicker ropes with smooth surfaces.
6. Features: Once the winding method is wrong, the result may become an incomplete slipknot, and the knot will fall apart when you pull hard. If the knot is pulled too tight, it will not be easy to untie; but if you hold the rope end with both hands and pull hard on both sides, it can be easily untied.
7. Introduction: Known as the king of knots, it is the most popular knot in the world and is used in various outdoor sports, even in all walks of life or in daily life. Frequently used in .
8. Use: Used when the rope is tied to other objects or formed into a loop at the end of the rope.
9. Characteristics: Easy to tie and untie, high security with coordination, wide range of uses, and varied.
10. Introduction: Used as the beginning and end of other knots.
11. Purpose: Usually used on items with equal force on both ends, suitable for horizontal pulling force.
12. Features: It has extremely high safety. However, if force is only applied on one end of the rope, the knot of the double knot may be messed up. or loosen.
13. Introduction: The function is the same as the double tack, but it is stronger.
14. Others: also known as Rolling Hitch, Magnus Hitch, Taut-line Hitch, and stop rope Knot (StopperHitch).
15. Introduction: This knot is very easy to tie, but difficult to open. Therefore, you should try to avoid using it on some ropes with good quality, and it is not suitable to use it on ropes that will be pulled very tightly, because after tightening, it will be difficult to untie.
16. Purpose: To connect two ropes together, usually two hard and soft ropes.
17. Introduction: It is called Prussian knot and mobile knot. Used for self-protection during travel and ascent.
18. Features: The grab knot can slide along the main rope when there is no force, and it will get stuck on the main rope when there is force.
19. Introduction: It allows you to move the knot up and down on the rope at any time.
20. Purpose: Shorten the long rope to avoid cutting it because it is too long. You can also use this method to strengthen the protection of the easily worn parts of the rope.
21. Characteristics: If the rope is too loose, the knot will easily loosen and lose its function.
22. Introduction: Have a circle that can be adjusted at will.
23. Purpose: binding and pulling items such as wood.
24. Characteristics: Although it is a convenient and reliable knot, it must be under tension, otherwise it will loosen and cause danger.
25. Also known as the square knot, among various types of knots, the flat knot is the most frequently used and well-known. Use a flat knot to connect ropes of the same thickness together. They are strong and easy to untie even if they bear a lot of tension.
26. You can use a flat knot to tie the rope to other objects. It is better to use a flat knot during rescue. It is very smooth and will not easily hurt the victim.
27. a. Place the right one on the left rope;
28 , b, loop downward, and then put the left rope end;
29, d, loop downward again. Check carefully, the two loops can slide against each other, and if threaded in the wrong position, it will not tie together (unravel), or it will be difficult to untie when tension is applied.
30. e. Pull the two ropes at the same time to tie the flat knot; or just use force from the loose end to ensure the tie.
31. f. After tying the flat knot, if you doubt whether it is reliable, you can tie another half knot of the live end of each end of the flat knot on the rope
32. Among all knots, the overhand knot is the simplest. First, bend the rope into a loop and pull the live end through the loop from behind.Tight and done.
33. The overhand knot has few uses other than tying a knot at the end of the rope (to prevent the rope from unraveling), but it Is a component of many other knots.
34. This knot is very fast to make. First, bend the rope into a loop, put the loop on a fixed object, pull it tightly, and then use the loose end and the Loop an overhand knot
35. Like the overhand knot, this knot can tie a knot at the end of the rope, but it is more effective than the overhand knot. First bend the rope into a loop, place the free end behind the fixed part of the rope, then wrap it around the fixed part and pass the free end through the front loop.
36. This is a fairly effective knot for tying a rope to an anchor. It can be used when the object (anchor) is too high to fit the knotted knot. First, make a loose \”8\”-shaped knot on the rope, wrap the live end around the object and pull it back, make a new \”8\”-shaped knot along the line of the original figure-8 knot, and then tie it up
37. Used to connect two ropes of the same or different thicknesses, which is more effective than a flat knot tied by two ropes of the same thickness. This knot is ideal for ropes made of different materials, especially wet or icy ropes.
38. This knot is simple to make and easy to untie when the rope is not under tension. If it is made correctly and the tension is steady and regular, the knot will not slip apart.
39. 1. Bend one rope into a ring shape, turn the live end a of the other rope to the right, go around the ring from behind, and then bend the live end from Pass this rope through the loop between another rope.
40. 2. Tighten. This knot automatically tightens when the tension increases.
41. Double braiding is stronger and more durable than single braiding, and works well on wet ropes, especially when the thickness of the two ropes is very different. However, even if both ropes are thick, the double braid connection is very knotty. If the tension on the rope is unstable, the ordinary single knot will easily slip. At this time, the advantages of the double knot will be more obvious.
42. 1. Bend the thicker rope into a ring, pass the live end a of the thin rope through the ring, and first move it to the live end of the thick rope. Next, go around the ring again starting from the front, and then pass the live end of the thin rope between the thin rope and the thick rope live end from the back.
43. 2. Wrap the live end of the thin rope around once again, and then pass it through the same place (between the thin rope and the thick rope live end).
44. 3. Tighten. If the knot is not tightened, the knot will easily loosen when stressed. It is not suitable to use smooth ropes, such as nylon fishing lines, to make this knot.
45. This knot can be used when connecting two soft ropes (or other materials), such as vines or metal wires. It is also useful for wet or slippery ropes, especially suitable for them. Connect the fishing line for fishing.
46. First soak the fishing line in the water to make it soft. Use this knot to connect the thin line tightly and firmly, but it is not easy. Untie, you can try this knot when you are not sure whether a flat knot or a single knot is effective. However, this knot cannot be used with thick ropes or nylon lines.
47. 1. Put the two threads together, with the ends in opposite directions, and wrap the live end of one thread around the other thread to make a simple overhand knot.
48. 2. Repeat with the other live end of the thread in the same way. 49. 3. Slightly tighten the two overhand knots, and then slide them towards each other. , make the two knots close together, and then tie the two knots
50. This knot works well for connecting materials with smooth surfaces, such as belts and cloth tapes. . When the situation is urgent and there is a lack of rope, you can even try it with sheets or other fabrics
51. 1. Make an overhand knot with the loose end of a strap. , do not tighten.
52. 2. Pass the live end of the other strap through the knot in the opposite direction of the overhand knot\’s motion.
53. 3. The loose end should be just inside the knot, so that the loose end will not slip when tightened.
54. This ring can slide and be tightened at will. First make a small single ring, and then pass the long end of the rope through this ring.
55. Do not tie the removable single ring around your waist, especially when mountaineering. The function of this ring is similar to a noose, which can be fatal.
56. This is another way toIt consists of a sliding lasso knot, but this knot has an obvious circular ring and is suitable for throwing and lassoing something, so it is a kind of lasso.
57. The lasso has various functions, but when surviving in the wild, if there is only one rope, then a lot of time and energy are spent trying to use this kind of rope. It is not wise to capture animals as this requires long practice. By the time you really need the rope, it may have been damaged by hunting. However, it\’s worth taking the time to practice hunting this way. Once you master the skill, it pays off in real tough situations.
58. 2. Bend a loop at a distance from the end of the rope.
59. 3. Fold the rope into a half-ring between the overhand knot and the loop.
60. 6. Pass the long end of the rope through the new rope loop.
Four. 8-character ligation method
1. First, tie the rope The end of the rope is folded towards the direction of the main rope.
2. Then wrap the end of the rope around the back of the main rope.
3. Next, pass this section through the rope loop on the right.
4. Finally, tighten the knot so that a single figure-8 knot is completed.
5. In Italy, people call the figure-eight knot the \”royal knot\” because the shape of the knot is exactly what the Italian royal family emblem looks like.
6. The figure eight knot also symbolizes honest love and unchanging friendship. Therefore, some people call the figure eight knot the knot of love.
7. The well-known figure eight knot is just like its name. The knot will appear in the shape of \”8\” after being tied. Mainly used for anti-slip. When the rope is thicker, cross the rope segments first, and the rope head goes around the main rope and passes through the rope loop before tightening; when the rope is thin, pass the rope head through the rope loop and tighten it. Even if the ends are pulled tightly, they can still be easily untied.
8. Application areas: navigation, rock climbing, outdoor sports, wild survival. Function: prevent ropes from detaching and preventing slipping.
