Teaching video of surgical knotting method

Knotting is one of the most commonly used and basic operations in surgery, because both hemostasis and suture need ligation, and the correct ligation depends on the operator's proficiency in knotting methods. The quality and speed of knotting not only affect the length of operation, but also affect the quality of operation and the prognosis of patients. Therefore, every learning surgeon must master this important basic operation technique.

The method of knotting the right hand in surgery (graphic)

The right-handed knot is similar to the left-handed knot, except that the single knot is mainly tied by the right hand. The positional relationship between the two lines is the same as that of the left-handed knotting method, but the knotting order is different. The first knot is tied with the index finger, and the second knot is tied with the thumb.

1. Pick up the lower thread end with your left hand, hold the upper thread end with your three fingers and palm of your right hand, and put the two threads together. Hook the thread below the right thread end with your right index finger and move it to the left (Figure 1).

2. Hook the left thread with the index finger of the right hand and lift the left thread to form a ligature loop with the index finger of the right hand in it (Figure 2).

3. Put the index finger and thumb of the right hand together, hold the intersection of lines, rotate the right hand, release the finger, and let the index finger and thumb in the ligation ring exchange positions (Figure 3).

4. Lift the left hand line, and hold the distal end of the left hand line with the thumb and forefinger of the right hand (Figure 4).

5. When the right hand rotates, the index finger puts the left thread into the ligature ring, the left hand releases the thread, pulls the left thread out of the ligature ring, and holds the left thread again (Figure 5).

6. Fasten, press the line with the index finger, and complete the single knot. At this time, the tying direction is that the right hand is close to the body and the left hand is opposite (Figure 6).

7. At the beginning of the second simple knot, press the right thumb on the end of the right hand line, and the line is attached to the back of the thumb. At the same time, the thumb abducts, and the left hand thread moves to the ventral side of the right thumb, forming a ligature loop with the thumb in it (Figure 7).

8. Put the thumb and forefinger of the right hand together, turn the wrist and replace the thumb in the ring with the forefinger (Figure 8).

9. The thumb and forefinger of the right hand are close together again, and the left hand thread is inserted into the ligation ring. The thumb of the right hand is still in the ligation ring, and the end of the left hand thread is taken out from the ligation ring, and the ligation is completed (Figure 9).
