This invention provides a continuous suture system, including an outer component, an inner component, a locking component, multiple anchor assemblies, and sutures. The outer component has a sleeve and a shaft connected to the distal end of the sleeve. The inner wall of the sleeve has multiple annular grooves arranged axially. The inner component has a handle and a movable part connected to the distal end of the handle. The movable part has a pair of elastic parts that can be laterally elastically deformed toward each other. Each elastic part has a locking part on its outer side. The elastic parts can be in a laterally elastic rebound state when the locking part is inserted into the annular groove and in a laterally elastic compression state when the locking part is located between the annular grooves and disengaged from the annular grooves. The locking component has a locked state that restricts the elastic parts to the laterally elastic rebound state and an unlocked state that allows the elastic parts to deform to the laterally elastic compression state. According to this invention, the operator can only move the locking parts of a pair of elastic parts and insert them into the proximal adjacent annular grooves at a time, ensuring accurate replacement of one anchor assembly.

The angle of the suture needle can be quickly adjusted in the pleural cavity, continuous suture is facilitated, unnecessary side injury caused by repeated access of the suture needle to the chest is avoided, free chest tissues such as lung tissues, arteriovenous and trachea can be assisted, and unnecessary fatal injury such as massive hemorrhage can be reduced.

The invention discloses a uniknot continuous suturing method for postpartum perineum anatomy reconstruction, and relates to the field of medical suturing methods, the uniknot continuous suturing method comprises the following steps: S1, initial suturing and fixing; s2, continuously suturing vaginal mucosa and involution hymen rings; s3, continuously suturing the perineum subcutaneous tissue; s4, performing continuous intradermal sewing; s5, rebuilding navicular fossa, and selecting a forward stitching method or a reverse stitching method according to the operation field direction to realize three-dimensional fine involution; and S6, removing residual lines and checking. According to the method, an integrated suturing mode of single knot starting and continuous walking is adopted, the postpartum perineum suturing operation process is simplified, the suturing operation time is shortened, the number of knots is reduced, and tissue foreign matter reaction and postoperative pain are reduced. According to the method, three-dimensional fine involution of key anatomical structures of the perineum is achieved through the specific navicular fossa reconstruction step, complications such as traumatic granuloma hyperplasia, scar contracture and poor healing of the perineum can be effectively prevented, long-term fast recovery of anatomical forms and functions of puerperae is guaranteed, and good clinical benefits are achieved.
