All kinds of knotting methods in surgery?
summary
Knotting is a very important technique in surgical operation, and it is one of the most basic operations. It runs through the whole process of surgical operation. Now more and more people are interested in medicine, especially in surgery. Surgery is a branch of medicine. Many people are more interested in surgery. Let's take a look at the following.
All kinds of knotting methods in surgery?
First: square knot, also known as flat knot, is composed of two single knots with opposite directions. The greater the tension in the coil, the tighter the ligation, and it is not easy to slip.
Second: when making a square knot, due to unskilled and uneven force of both hands, the knots are vertically overlapped with each other and cannot be tied firmly, thus forming a sliding knot instead of a square knot. Attention should be paid to avoid it. Changing the distribution and direction of pulling force can avoid it. This knot should not be used in operation, especially in ligation of large vessels.
Third: triple knot, also known as triple knot, is to repeat the first knot on the basis of square knot, and the direction of the third knot is opposite to that of the second knot, so as to strengthen the friction force between ligation lines and prevent loose and slippage of the lines, so it is firm and reliable. It is often used for ligation of larger blood vessels and more tissues, and also for suture of tissues with greater tension. This knot is also commonly used for tying nylon thread and catgut. The disadvantage is that the head of ligation thread in the tissue is large, so that large foreign bodies are left in the tissue.
matters needing attention
Firm and reliable ligation depends on skillful and correct knotting technique. The speed and quality of knotting is not only related to the length of operation time, but also affects the quality of operation and the prognosis of patients, even endangers the life safety of patients. Therefore, it is necessary to master the surgical knotting technique correctly and skillfully.
