Automatic anastomosis duramater system

The invention discloses an automatic anastomosis duramater system, which comprises a flexible latch system and an artificial duramater, wherein the flexible latch system is made from an absorbable material and the flexible latch system comprises an annular base and two semicircular clamping arms; the artificial duramater is fixed to the bottom face of the base; a communicating shaft is arranged in the middle of the base; two ends of the clamping arms are rotatably connected to the communicating shaft by virtue of torsional springs; a plurality of clamping grooves are formed in the top face of the base; a plurality of clamping pins are arranged on the bottom face of the clamping arms; and the clamping pins of the clamping arms are clamped in the clamping grooves of the base when the torsional springs are located on free positions. According to the automatic anastomosis duramater system provided by the invention, the artificial duramater on the base face of the base and an autogenous duramater on the top face of the base are fastened by virtue of the two semicircular clamping arms, and the artificial duramater and the autogenous duramater are automatically anastomosed as the base and semicircular latches are absorbed by a human body, so that an operating time in a surgery is greatly shortened and operative risks and operative complications are reduced.
