Abstract

A suture method includes a first arrangement step of using a first treatment device including first/second grasping pieces to hook the first grasping piece to a first position of peripheral tissues of a lesion; a second arrangement step of hooking the second grasping piece to a second position of the peripheral tissues; a grasping step of grasping the first position and the second position while pressing the first position and the second position to the peripheral tissues; a retracting step of retracting the lesion site toward a proximal end side of the first treatment device while drawing the first position and the second position grasped by the first treatment device; and a suturing step of suturing a first suturing position at an external side of the first position and a second suturing position at an external side of the second position in the peripheral tissues.

Claims10

Dependent claims

A suture method for suturing peripheral tissues of a lesion site, the method comprising:

cauterizing the peripheral tissues of the lesion site to form a first marking and a second marking, the first marking and the second marking being positioned opposite to each other across an entirety of the lesion site;
putting a first grasping piece of a forceps in the first marking;
putting a second grasping piece of the forceps in the second marking;
grasping the entirety of the lesion site by the first grasping piece and the second grasping piece while the entirety of the lesion site is between the first grasping piece and the second grasping piece;
retracting the forceps toward a proximal direction of the forceps while the entirety of the lesion site is grasped between the first grasping piece and the second grasping piece;
and
suturing a first suturing position of the peripheral tissues of the lesion site at an external side of the first marking and the second marking relative to the lesion site in a radial direction.
