[0027] The two ends of support frame 3 are fixedly connected with first magnetic force generator and second magnetic force generator respectively, support frame 3 and magnetic force device 2 cooperate to form U-shaped, and transmitter 1 is arranged in the middle part of support frame 3.Wound is located between first magnetic force generator and second magnetic force generator, and the transverse width of wound is less than the width between first magnetic force generator and second magnetic force generator.Wound is located between first magnetic force generator and second magnetic force generator, and the length of wound is less than the length of first magnetic force generator and second magnetic force generator.

[0028] The first and second magnetic generators each comprise several independent magnetic pole units 4. The magnetic pole units 4 are arranged in a horizontal straight line and are electrically connected to the control center. Each magnetic pole unit 4 generates a horizontal magnetic field B1 and a horizontal magnetic field B3. Magnetic field B1 guides the suture needle to move obliquely through the wound. Magnetic field B3 guides the suture needle to move obliquely outside the wound. Each magnetic pole unit 4 also generates a vertical magnetic field B2. Magnetic field B2 guides the suture needle to penetrate vertically inside and outside the wound.

Next, it shuttles outwards, and after a certain distance, L1 stops at B1, while R1 generates a vertically upward magnetic field B2, guiding the suture needle out of the wound until the needle tip 6 is fully exited. Finally, it shuttles externally, with R1 stopping at B2 and generating a magnetic field B3 pointing towards L1, guiding the suture needle to shuttle obliquely from outside the wound. Finally, it inserts externally, with R1 stopping at B3 after a certain distance, while L2 generates a vertically downward magnetic field B2, guiding the suture needle vertically into the wound. This process continues sequentially: internal shuttle, external exit, external shuttle, and external insertion, until the wound is completely sutured.
