The incision is often sutured after the surgical operation, and when the skin tension on two sides of the incision to be sutured is high, tension-reducing suturing is needed to prevent the incision from cracking. I.e., multiple layers of tissue are sutured simultaneously using relatively thick sutures, and liners are often used to reduce the cutting effect of the sutures on the tissue during suturing.

The existing suture mode adopting the tension reducing needle and the thick suture mainly has the following problems:

1. the outer wall of the suture is a cambered surface and lacks elasticity, after the suture is bound with tissues, even if the contact surface between the outer wall of the thick suture and the tissues is still small, the local pressure of the suture at the suture position to the tissues is very large, the suture obviously cuts the tissues, and the suture is more prominent particularly under the conditions of combined infection, larger tissue brittleness and longer suture retention time;

2. the liner used for reducing tissue cutting is mostly made of non-absorbable materials such as rubber and silica gel, and the incision needs to be completely removed after healing, so that the liner can be only placed below the exposed part of the annularly bundled suture, at the moment, the liner has a protection effect on body surface skin tissues covered by the liner, but the tension of the suture is increased due to the action of the liner, and the suture with increased tension can aggravate cutting on other annularly bundled tissues which are not covered by the liner;

3. when the tissue tension is lowered and the tissue is cut, the suture portion becomes loose, the closed state of the incision cannot be maintained, the tied suture knot is small and tight, and is difficult to untie and re-tie, and if the residual suture is too short after the suture knot is removed, the suture cannot be re-tied, and the too long pad used for reducing the tissue cutting is also not favorable for re-tying the suture.
