产科裂伤是阴道分娩常见的并发症，若修复不当易引发盆底功能障碍等远期问题，规范开展裂伤修复对提升产科质量具有重要意义。直肠阴道隔、会阴体及肛门括约肌复合体等是维持盆底结构完整与功能正常的关键结构，在阴道分娩过程中易发生损伤，故此类裂伤的修复需强调基于解剖学的结构与功能重建，修复策略应遵循“解剖复位优先、功能导向”的核心原则，缝合前应充分评估裂伤程度，通过充分止血、分层对合、重建肌肉筋膜的解剖连续性，并结合以功能恢复为核心的围术期综合管理，以促进患者盆底结构与功能的整体康复。

Obstetric lacerations are common complications of vaginal delivery，and inadequate repair is prone to inducing long-term complications such as pelvic floor dysfunction. Therefore，standardized repair of obstetric lacerations is of great significance for improving the quality of obstetric clinical practice. The rectovaginal septum，perineal body，anal sphincter complex and other structures are key components in maintaining the structural integrity and normal physiological function of the pelvic floor，and they are vulnerable to injuries during vaginal delivery. Hence，the repair of such obstetric lacerations should emphasize structural and functional reconstruction based on anatomy，and the repair strategy must abide by the core principle of "prioritizing anatomical reduction and functional orientation". Prior to suture，the degree of lacerations should be fully evaluated. Clinical interventions should include adequate hemostasis，layered apposition of injured tissues，and reconstruction of the anatomical continuity of muscles and fasciae. In addition，the implementation of comprehensive perioperative management centering on functional recovery is also essential，so as to promote the overall rehabilitation of the pelvic floor structure and function of patients.
