Surgical treatment is often required for conditions that result in nerve damage, severely affecting life. At present, the foramen mirror operation has become the mainstream technology of lumbar disc herniation.
The fibrous ring stitching technology under the intervertebral foraminicope is different from the stitching technology on the body surface, and needs a longer minimally invasive instrument to penetrate the suture into the fiber and fix the suture on the fibrous rings on the two sides of the intervertebral disc rupture, and the suture is locked by using a knot pusher after knotting, so that the fibrous ring rupture is tensioned and closed. There are some problems in clinic, and for some patients, the fiber hole is smaller, and the fiber hole can be effectively tensioned and closed when knotting. However, in the case of larger fiber ring openings, the fiber ring openings cannot be tensioned and closed when knotted, so that suture failure is caused.
At present, different treatment modes are needed to be adopted for suturing the fiber ring openings with different sizes, when the existing operators judge the fiber ring suturing treatment modes, the lengths of the fiber ring openings are usually visually detected according to experience of the operators, the length prediction failure of the fiber ring openings is easily caused, and an unsuitable treatment mode is adopted.
