Abstract

A medical procedure and a system are provided so that two visions are obtainable through natural orifices by means of two observational apparatuses, or one the two visions is selectable. The medical procedure through a natural orifice comprises: forming an orifice in a hollow organ by using a device inserted into the hollow organ from a natural orifice of a patient; introducing a first observation device from said orifice formed in said hollow organ into an abdominal cavity; introducing a second observation device from said orifice formed in said hollow organ into the abdominal cavity; arranging said second observation device in a position different from that of said first observation device; simultaneously or selectively displaying an image obtained from said first observation device and an image obtained from said second observation device; and performing a desired procedure in the abdominal cavity while confirming the images.

Claims

1. A medical operation comprising:

introducing a holding member having a first holding portion which is provided at a distal end of an insertion portion into an abdominal cavity through an opening which opens percutaneously;

introducing an introducing device having a second holding portion which detachably holds an observational device having a connecting member which is detachably connected to said first holding portion into the abdominal cavity through a natural orifice;

fixing said first holding portion to said connecting member of said observational device;

detaching said second holding portion from said first holding portion which is fixed to said observational device and to said connecting member after fixing said first holding portion to said connecting member; and

observing said abdominal cavity by controlling a position and direction of said observational device that is fixed to said first holding portion by operating said holding member, in the state where said observational device is separated from said second holding portion.

2. The medical operation according to claim 1, wherein the introducing of the introducing device comprises introducing a laparoscope into the abdominal cavity, and said second holding portion is a grasping device which grasps said observational device.

3. The medical operation according to claim 1, wherein the introducing of the introducing device comprises introducing a flexible endoscope into the abdominal cavity through a natural orifice, and said first holding portion is a manipulator which holds said observational device.

4. The medical operation according to claim 1, wherein said observational device is a capsule endoscope.

5. The medical operation according to claim 4, wherein the connecting of said first holding portion and said observational device comprises connecting said first holding portion and said observational device in a direction which is perpendicular to an observation direction of said capsule endoscope.
