A method for suturing a perforation formed in a hollow organ comprises the steps of: causing plural end portions of the suture thread to puncture a tissue around the perforation in the same direction as each other; connecting the end portions of the suture thread to each other; and tightening up the suture thread after connecting the end portions of the suture thread with each other.
摘要:
An over-tube of the present invention is an over-tube which guides a device having an insertion section to be inserted into a body of a patient, when inserting the insertion section into or retracting the insertion section from the body of the patient, wherein: a gas-supplying passage is defined between an inner face of the over-tube and the device to be inserted into the over-tube; the gas-supplying passage communicates with a gas-supplying port which is provided on a proximal end side of the over-tube, and a communicating port which is formed on an over-tube insertion section and supplies a gas into a trachea of the patient; and a first sealing member which secures an air passage for communicating the gas-supplying passage and the trachea of the patient via the communicating rod by sealing between a body wall of the patient and the communicating port, is provided on a periphery of an over-tube insertion section.

A medical procedure through a natural body orifice according to the present invention includes: introducing a first device having an insertion portion, from a patient's natural orifice into a hollow organ; performing a first medical procedure using the first device; withdrawing the first device from the body, and introducing a second device having an insertion portion, from a patient's natural orifice into the body; and performing a second medical procedure using the second device, wherein the first medical procedure is performed prior to the second medical procedure for performing the second medical procedure.
摘要:
The method for accessing the abdominal cavity according to the present invention, includes: introducing a first flow path into the abdominal cavity; introducing a second flow path into the hollow organ from the natural orifice of the living body, and performing a pressure control, using the first flow path and the second flow path, so that the pressure within the hollow organ is lower than the pressure of the abdominal cavity, and forming an opening in the wall of the hollow organ from the inside of the hollow organ when the pressure within the abdominal cavity, as accomplished by pressure control, is equal to or lower than the pressure of the abdominal cavity, and inserting a device for performing a medical procedure through the opening.
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:
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.
摘要:
A medical retainer is provided capable of independently controlling supplying air and water to a hollow organ like a stomach and a lumen of a small intestine. The medical retainer for sealing a fluid, the retainer being subject to be retained in a gastrointestinal tract of a patient, the medical retainer includes: a sealing section for sealing the fluid, the sealing section making contact with a wall of the gastrointestinal tract; a main body having passageways; and directional valves disposed in the passageways for allowing one of upward flow and downward flow of the fluid relative to the position of the retainer.
