Abstract
A pushing tool of the present invention includes a tissue pushing part having a shaft portion that is formed in a rod-shape, a linear portion including a pressing portion that is connected to the shaft portion and extends in a longitudinal direction, and a stopper maintaining an angle between the shaft portion and the linear portion at a desired angle when the pressing portion is closely pressed against an outer surface of a hollow organ.
Claims3
A method of suturing a hollow organ comprising:
- manipulating a pushing tool having a shaft portion and a linear portion including a pressing portion, so as to form an angle between the shaft portion and the linear portion;
- pressing closely the pressing portion extending in a longitudinal direction against an outer surface of the hollow organ;
- reducing an internal pressure of the hollow organ to invert a first site with which the pressing portion is in contact while maintaining a state in which the pressing portion is closely pressed against the outer surface;
- and
- suturing a second site and a third site, which face each other across an inversion line formed by inverting the first site, such that a predetermined positional relation is maintained,
- wherein the angle formed between the shaft portion and the linear portion is a right angle.
