Claim 6:
7. A method for suturing along a path by utilizing the apparatus according to claim 1, comprising following steps:
S1, embedding the metallic stent to be sutured into the groove, and then sheathing the inner strut inside the sutured material, installing the driving mechanism at the rear end of the spiral suturing needle and compressing the spiral suturing needle;
S2, rotating, by the driving mechanism, the spiral suturing needle, to enable the suturing needle tip to repeat a process of piercing into the sutured material, bypassing a metal wire of the metallic stent, and piercing out of the sutured material, so that the compressed spiral suturing needle recoveries elasticity with the rotating action and continuously moving forward along the path of the groove;
S3, rotating, after the spiral suturing needle completes the process along the path, the suturing needle tip out of the groove, disabling the action of the driving mechanism, installing the recovery mechanism at the front end of the spiral suturing needle, and providing, by the suture-feeding mechanism, the suture to the suture-piercing hole;
S4, rotating, by the recovery mechanism, the spiral suturing needle, so that the spiral suturing needle is rotated out of the groove, and binding, by using the suture at the tail portion of the spiral suturing needle, the metallic stent and the sutured material;
S5, taking up, by the suture-taking-up mechanism on the path of the groove, the suture, tightening, by the recovery mechanism and the suture-feeding mechanism, the suture, and repeating the taking-up and tightening operations; and
S6, removing, after the rear end of the spiral suturing needle is rotated out of the groove, the spiral suturing needle and the recovery mechanism, knotting two ends of the suture to complete the suturing around the path.
