Abstract

The embodiment of the invention provides a suture device of a surgical operating instrument and the surgical operating instrument. The stapling device includes an end housing and an end stapling mechanism. The end housing includes a top portion and a bottom portion. The end stapling mechanism includes a staple channel, a staple pusher, and an anvil. The suturing nail channel is located between the top and the bottom and extends in the first direction, and a plurality of suturing nails are arranged in the suturing nail channel in a stacked mode in the first direction. The nail pushing device is located between the suturing nail channel and the top and is arranged to push the suturing nails out of the suturing nail channel in the second direction so that the suturing nails can stretch out of the bottom, and the second direction is perpendicular to the first direction. An anvil is located between the staple channel and the bottom, the anvil being configured to cooperate with the staple pusher to bend the staple. According to the suturing device, the number of suturing nails contained in the suturing nail channel can be increased, and the internal structure of the end suturing mechanism is more compact.
