This treatment device for endoscope is used for cutting body tissue while the treatment device is retractably projected from a catheter. The treatment device includes: a control wire inserted into the catheter; and a cutting electrode mounted at the distal end of the control wire with the cutting electrode being imparted a bent configuration in advance. The cutting electrode elastically deforms in a state where the cutting electrode is retracted into the catheter, thereby assuming such a shape as to resemble the configuration of the catheter.

A tissue fastener production method of clamping two living tissues together by bringing the two living tissues into close contact includes the following steps: fixing one end of a wire material made of a metal to a shaft body, and winding the wire material around an outer periphery of the shaft body while twisting the wire material round an axis of the wire material, thereby forming a coil on which a predetermined force is exerted in the winding direction; heat treating the wire material to impart superelasticity thereto; and deforming the wire material to which the superelasticity is imparted in a range in which the wire material is elastically deformable, and reversing the winding direction of the coil in a direction reverse to the winding direction of the coil wound in the step of forming the coil so as to obtain an initial tension corresponding to the predetermined force.
摘要:
A fistulectomy method of forming a fistula between a first duct and a second duct is provided. The method including: inserting an insertion portion of an endoscope having a channel into the first duct; inserting a treatment instrument into the channel; feeding a distal end of the treatment instrument into the second duct through the first duct; discharging a first magnet from the distal end of the treatment instrument to the second duct; pulling the treatment instrument from the second duct; discharging a second magnet to the first duct; and attaching the first magnet and the second magnet magnetically when the first and second ducts are between the first and second magnets.
摘要:
This capsule endoscope system includes: a capsule endoscope having an internal lumen; a catheter tube connected to the capsule endoscope; and a connection portion for connecting the distal end of the catheter tube to the capsule endoscope so that the catheter tube is communicatively connected with the internal lumen of the capsule endoscope.

摘要:
A fistulectomy method of forming a fistula between a first duct and a second duct includes sticking a puncture needle into the second duct from the inside of the first duct through a wall surface of the first duct and a wall surface of the second duct, arranging the puncture needle at a position of a central axis and sticking a coil needle around the puncture needle from the first duct toward the second duct to couple the first duct with the second duct, maintaining the coil needle in a state where the first duct communicates with the second duct, and forming the fistula on an inner side of the coil needle.
摘要:
A treatment method on tissues in a body cavity includes: a first step of forming a hole for communicating first body tissue with second body tissue while both are in close contact with each other; and a second step of endoscopically inserting a treatment device into the second body tissue through the hole.
摘要:
The applicator related to the present invention is provided with a flexible sheath longer than the overall length of an instrument channel of a flexible endoscope; an operation part used outside the instrument channel; a deployed section that can be made to protrude from the front end of the sheath by operating the operation part and to pierce a tissue; a tissue fastening tool made of a superelastic wire formed in coil shape and housed inside the deployed section in a substantially extended condition; and a pusher that pushes out the tissue fastening tool from the deployed section when the operation part is operated.
