摘要:
An endoscopic treatment tool according to the present invention is an endoscopic treatment tool which is inserted into hollow organs via the mouth, nose, anus, or other natural orifice of the patient and performs suturing treatment within the hollow organs or abdominal cavities, includes: a hollow organ lining support which is smaller than the smallest diameter of a passage from a natural orifice of the hollow organ, the hollow organ lining support being able to expand so as to have a diameter larger than the smallest diameter of the passage from the natural orifice of the hollow organ.

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 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.
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 method for suturing a perforation of the present invention comprises the steps of: inserting an observation device into the hollow organ and confirming a proposed incision line for incising the hollow organ; determining a position to be sutured before incising the hollow organ along the proposed incision line; and suturing the perforation by tightening up a suture thread that penetrates through the hollow organ via the position to be sutured after incising the hollow organ along the proposed incision line and performing a medical treatment in an abdominal cavity through the perforation.
摘要:
The medical procedure via a natural opening according to the present invention includes: adjusting the patient's body so that a target site on the anterior wall of a hollow organ faces in the direction opposite to the direction of gravitational force; introducing a liquid inflow conduit in the vicinity of the target site, and flowing liquid into the hollow organ via the liquid inflow conduit, to form a liquid holding area and a gas retaining area inside the hollow organ; introducing an observation device into the hollow organ, and confirming the position of the target site from the position of the gas retaining area; and incising while observation the target area.
摘要:
A perforation suturing method has the steps of: inserting a needle into a wall of a hollow organ at a periphery of the perforation formed in the hollow organ, and piercing the wall; withdrawing the needle from the wall after delivery of an anchor attaching suture thread from the needle, and having the suture thread transit the wall; and tightening the suture thread so that the mated insertion points at the time of insertion of the needle into the wall approximately coincide after having the needle pierce the wall at the periphery of the perforation a plurality of times, and making surfaces of the wall where the insertion points are formed coincide with each other.
