The invention relates to a minimally-invasive fascia closer. The minimally-invasive fascia closer comprises an operating rod, a pair of rotating arms and a thread delivery needle, wherein the rotating arms are arranged at the lower end part of the operating rod and are controlled to open or close by a driving mechanism; the thread delivery passage which is used for enabling the thread delivery needles to penetrate through are formed in the rotating arms, and the protection mechanism which is used for preventing the needle head from puncturing tissue is arranged at outlet of the thread delivery passage. The minimally-invasive fascia closer provided by the invention has the aim that internal wall suture can be rapidly and safely achieved. The minimally-invasive fascia closer has the advantages that the protection mechanism is arranged at the outlet of the thread delivery passage in the rotating arms, so that the hazard that needle tips of the thread delivery needles prick and puncture internal organs of patients can be effectively avoided, and the speed of suture of operators is effectively increased; the external contour size of an axial cross section of the operating rod and closed rotating arms is smaller than that of an inner bore of a puncture outfit, and the operating rod can be inserted into a puncture hole by directly using the puncture hole formed by the puncture outfit, so that a process of finding the puncture hole again is avoided, the operation can be more convenient, and the surgery time is saved.
