Fibrous ring minimally invasive suturing instrument

The utility model discloses a fiber ring minimally invasive suturing instrument which adopts a single-needle-tube suturing instrument, two ends of a suturing line are respectively inserted into two sides of an incision by a needle, so that two line knots of the suturing line penetrate into the two sides of the incision, finally, the incision is bound by the suturing line, and the incision suturing is completed. The ejector rod of the rod-shaped ejector pin is controlled by the safety knob and the secondary limit switch to operate twice in the needle tube of the straight needle. Due to the fact that the suture knots are arranged at the two ends of the suture line, the suture knots of the suture line cannot be withdrawn from soft tissue after entering the soft tissue. The needle distance between the two needles and the direction of the suture needles can be automatically controlled, so that the suture process is more accurate, the suture is more reliable, the problems that the needle distance between the two ne
