Abstract：Objective To perform an improved design of the rectovaginal fistula repair device based on magnetic compression
technique. Methods The defects of the original rectovaginal fistula repair device based on magnetic compression were analyzed, a
pinhole fixed structure scheme was put forward, and a magnetic anastomosis forceps for magnetic closure of rectovaginal fistula was
designed. Results The design of the pinhole structure could effectively prevent the magnet from slipping off. The structure of the
magnetic rod of the magnetic anastomosis clamp could play a role in fixing the anastomotic magnet and was favorable for placing
the anomaly magnet. Conclusion The improved design of the rectovaginal fistula repair device based on magnetic compression is
feasible and is beneficial to the anastomosis operation.
