A medical instrument includes a medical needle configured to puncture a tissue, and a tissue-supporting member configured to be inserted into the lumen of the medical needle and supports the tissue. The medical needle includes an insertion portion that has a longitudinal axis, a lumen that is formed along the direction of the longitudinal axis of the insertion portion, an opening portion that is formed at the distal end of the insertion portion while being connected to the lumen, and a puncturing portion that is formed in the periphery of the opening portion and has a pair of projections sharply protruding in a direction extending toward the distal end from the proximal end of the insertion portion.

An endoscope treatment instrument provided with a flexible transmitting member, a treatment portion that is attached to the distal end of the transmitting member, and an actuator which is attached to the proximal end of the transmitting member and is for operating the treatment portion, this endoscope treatment instrument being designed to transmit the action of the actuator to the treatment portion via the transmitting member. The transmitting member consists of the connection in the longitudinal direction of a first coil sheath that has excellent rotation follow-up and good relative bending properties, and a second coil sheath that has excellent rotation follow-up and good ease of motion in the relative longitudinal direction.

A selective cannulation method for a lumenal tissue's branch section includes: a first step for guiding an endoscope having a channel to an aperture section of the lumenal tissue; a second step for inserting a distal end of an endoscopic treatment instrument through the channel into the aperture section of the lumenal tissue; a third step for having the distal end of the endoscopic treatment instrument make contact with a pipe wall extending from the aperture section of the lumenal tissue to the branch section at two opposed points on the pipe wall by deforming the distal end of the endoscopic treatment instrument; a fourth step for sliding and moving the distal end of the endoscopic treatment instrument to the branch section while having the distal end of the endoscopic treatment instrument make contact with the pipe wall; and a fifth step for inserting the distal end of the endoscopic treatment instrument into a predetermined branch lumen divided from the branch section.

An intraluminal endoscope inserting method according to the present invention is a method of forming a first opening in a wall of a first luminal organ while observing optical and ultrasonic images formed by an ultrasonic endoscope inserted into a first luminal organ through a natural opening, forming a second opening in a wall of a desired second luminal organ adjacent to the first luminal organ through an abdominal cavity space from the first opening, leading the ultrasonic endoscope into a second luminal organ from a second opening and performing observation and treatment, and after the treatment and the like, stitching the openings. This makes it possible to insert the endoscope with a skill same as that required for a normal endoscope test and makes it easy to insert the endoscope even into luminal organs irregularly connected to with one another in a body cavity.

Endoscopic surgical operation method includes: a step of lifting a living tissue including an diseased tissue located distally relative to an operation channel of an endoscope inserted through a natural orifice; a step of suturing a proximal region and a distal region of the living tissue positioned basal relative to the diseased tissue lifted by a suturing means section projecting distally from the operation channel of the endoscope after the lifting; and a step of resecting the living tissue between the sutured regions and the diseased tissue endoscopically after suturing the proximal region and the distal region of the living tissue surrounding the diseased tissue.
