It is the basic condition to ensure good healing, and it is also one of the basic operating techniques of important surgery. Different parts of tissues and organs need to be sutured in different ways and methods. Suture can be done with a needle holder or with a straight needle by hand. In addition, there are skin staplers, digestive tract staplers and closers.
Extended data:
It is necessary to ensure that the suture wound or the wound is well matched. Suture should be carried out in layers, according to the anatomical level of the tissue, so that the tissue level is tight, not involved in or sewn into other tissues, leaving no residual cavity to prevent hydrops, hematocele and infection. The distance between the wound edge and the needle distance of the suture must be the same, so that it looks beautiful. More importantly, the stress is consistent with the shared tension, and the suture is tight and does not leak.
Pay attention to the tension at the joint. The tightness of ligation suture should be based on the tight connection of incision edge, and should not be too tight. In other words, sooner or later, the wound healing is not completely proportional to the tightness, and too tight or too loose will lead to poor healing. When the wound is in a state of tension, tension-reducing suture should be performed. If the wound is too big, you can consider transferring skin flap to repair or skin grafting.
The choice of suture and suture needle should be appropriate. Sterile incision or lightly polluted wound can be treated with silk thread after debridement, disinfection and cleaning. Absorbable suture can be used for infected or seriously polluted wound, and corresponding non-invasive needle and thread should be used for vascular anastomosis.
