Technical Field
The invention relates to the technical field of suture, in particular to a tension reducing suture.
Background
The stretch-reducing suturing method is a suturing technique for which there is a large skin tension at the incision, and the purpose is to prevent the incision from being ruptured. The tension reducing stitching method is applicable to the following cases: patients with poor nutritional status, elderly and frail patients, patients who have recently needed secondary surgery and re-enter the original incision, patients suspected of having an abnormal healing post-operative incision, etc.
Because the tension reducing suture is a full-layer suture to the skin, subcutaneous and muscle layers, compared with the common suture mode, the tension for splitting the incision is released in the subcutaneous layer, and the skin layer is prevented from splitting due to the tension. The traditional No. 10 silk thread is thinner, even if a rubber tube is added as an outer sleeve, the tension of a suture incision only acts on local tissues, the stress range of the tissues is small, skin and subcutaneous tissues are easy to cut, and thus the incision of a patient and surrounding skin are damaged again. Moreover, if the surgeon does not tie a knot to the suture firmly, the suture itself is easily worn and cannot provide sufficient suture tension, which may result in increased tension in the incision and may be detrimental to the healing of the incision. In severe cases, pain may be caused to the patient, and the incision may be opened again.
In summary, the traditional tension reducing suture can cause cutting damage to local skin of the incision, the suture ligature part can be loosened, the suture is easy to abrade, and the incision cannot be ensured to be cracked again.
