When performing surgery, the protective cover 5 is removed, and the tissue to be cut is placed between the staple cartridge frame 1 and the suturing base on the stapler. The suturing base and the staple cartridge frame 1 are used to press the tissue to be cut. When pressing, the suturing base pushes the tissue to squeeze the pressing strip 19.

When performing surgery, the protective cover 5 is removed, and the tissue to be cut is placed between the stapler frame 1 and the suturing base on the stapler. The suturing base and the stapler frame 1 are used to press the tissue to be cut. When pressing, the suturing base pushes the tissue to squeeze the pressing strip 19. Under the action of the pressing spring 17, the pressing strip 19 is pushed to clamp and fix the tissue between the stapler frame 1 and the suturing base, thereby ensuring that the tissue to be cut does not slide during cutting, thereby ensuring the cutting quality and the effect of subsequent suturing.

After the suturing slider 8 moves to the left side of a suturing top block 12, the left suturing top block 12 cooperates to suturing, when the cutting of the tissue is completed, the suturing slider 8 moves to the leftmost side of the nail magazine frame 1, thereby completing the suturing operation of the cut tissue. The device uses the adjacent side walls of the suturing top block 12 and the suturing slider 8 to adopt inclined surfaces to achieve synchronous movement of the left and right ends of the suturing nail 15 in the vertical direction, thereby ensuring the suturing effect. After the operation is completed, the nail magazine frame 1 can be removed for replacement.
