A
cutting and suturing mechanism of a labial
cutting anastomat comprises an outer protective shell, a
cutting nail pushing sleeve arranged in the outer protective shell, a nail bin sleeve installed at an opening of the outer protective shell and a pair of blades which are arranged between the outer protective shell and the cutting nail pushing sleeve and fixed to the cutting nail pushing sleeve. Two rows of nail bins are formed in the nail bin sleeve around the two sides of a nail bin sleeve cavity in an arc-shaped mode at intervals, suturing nails are arranged in the nail bins, suturing nail
gasket grooves are formed in the positions, located on the two rows of nail bins, of the side face, away from the cutting nail pushing sleeve, of the nail bin sleeve, suturing nail gaskets are arranged in the
gasket grooves, and a blade receding groove is formed in the position, corresponding to the blade, of the nail bin sleeve. When the cutting nail pushing sleeve moves forwards and pushes the suturing nail to act, the suturing nail can achieve suturing of the
labia after penetrating through the suturing nail
gasket. The device has the advantages that cutting and suturing can be completed at the same time under the condition that the
labia is turned outwards, the operation difficulty is reduced, the situation that a suturing nail is embedded into the
labia to cause pain to a patient is avoided, automatic falling of the suturing nail is facilitated, and the appearance after the labia is recovered is improved.
