Method of lifting diseased part, tissue lifting system, and indwelling tool
A method includes providing an indwelling tool having a magnetic body at the inside of a luminal organ by inserting the tool into a working channel inserted from a natural opening of a living body to the luminal organ, in a manner such that an axis along a length of the magnetic body is arranged substantially parallel to a length direction of the working channel; disposing the tool in a vicinity of a diseased part of the luminal organ; applying a magnetic field to the magnetic body by using a magnetic field generating device provided at the outside of the luminal organ, so as to attract the magnetic body and make a side face of the magnetic body along the axis thereof push against a tissue in the vicinity of the diseased part; and lifting a tissue around a position of the tool, which includes the diseased part, by applying a magnetic force to the magnetic body by using the magnetic field generating device.
1 . A method of lifting a diseased part, comprising the steps of:
providing an indwelling tool having a magnetic body at the inside of a luminal organ by inserting the indwelling tool into a working channel which is inserted from a natural opening of a living body to the luminal organ, in a manner such that an axis along a length of the magnetic body is arranged substantially parallel to a length direction of the working channel;
disposing the indwelling tool in a vicinity of the diseased part produced in the luminal organ;
applying a magnetic field to the magnetic body by using a magnetic field generating device which is provided at the outside of the luminal organ, so as to attract the magnetic body and make a side face of the magnetic body along the axis thereof push against a tissue in the vicinity of the diseased part; and
lifting a tissue around a position of the indwelling tool, which includes the diseased part, by applying a magnetic force to the magnetic body by using the magnetic field generating device.
2 . The method of lifting a diseased part, in accordance with claim 1 , wherein the step of providing the indwelling tool at the inside of the luminal organ includes a step of providing the indwelling tool via the working channel which is of an endoscope having an observation device, the endoscope being inserted from the natural opening of the living body to the luminal organ.
3 . A tissue lifting system comprising:
an indwelling tool having an anchor fit to the inside of a luminal organ of a living body, and a magnetic body having an elongated shape, which is divided into two magnetized polar parts on either end along a longitudinal axis of the magnetic body, and
a magnetic force generating device which is provided at the outside of the luminal organ and has a magnetic body having two poles arranged on an end thereof toward the luminal organ, wherein said two poles correspond to said either end of the magnetic body of the indwelling tool.
4 . The tissue lifting system in accordance with claim 3 , wherein at least a part of a side face of the magnetic body of the indwelling tool is a plane which is parallel to the longitudinal axis.
5 . An indwelling tool comprising:
an anchor fit to the inside of a luminal organ; and
a soft magnetic body which is magnetized when being exposed in a magnetic field, wherein the soft magnetic body has a side face along a longitudinal axis of the soft magnetic body, the side face being pushed against a tissue inside the luminal organ, and a non-magnetic material is attached to either end of the magnetic body along the longitudinal axis.
6 . The indwelling tool in accordance with claim 5 , wherein at least a part of a side face of the magnetic body is provided with a plane which is parallel to the longitudinal axis.
7 . An indwelling tool comprising:
an anchor fit to the inside of a luminal organ in a living body, and
a magnetic body having an elongated shape, which is divided into two magnetized polar parts on either sides which interpose a longitudinal axis of the magnetic body.
