Abstract
A device insertion method for observing the lateral wall of the lumen includes: rotating a hollow organ by changing a body position; turning the tip of the device to the lateral wall of the lumen by rotating the device; and retracting the organ with the device itself by rotating the device, In other embodiments, an endoscope insertion method for observing the lateral side of the organ includes: rotating a body cavity by changing a body position; turning the tip of the flexible endoscope to the lateral side of the organ by rotating the flexible endoscope; and retracting the organ with the flexible endoscope itself by rotating the flexible endoscope.
Claims14
A device insertion method, comprising inserting a device having a holding portion and a tip into a lumen of a hollow organ, the method further comprising:
- (a) rotating a hollow organ by 45 to 135 degrees by changing a body position of a patient to a semilateral, lateral, or semiprone position for observing a lateral wall of a lumen of the hollow organ, wherein the body position was a supine, semi-recumbent, sitting, lithotripsy, or prone position,
- wherein if the patient is placed in the body position other than the semilateral, lateral, or semiprone position and the body position must be changed to the semilateral, lateral, or semiprone position during a procedure, the device remains inserted, or the device is removed, the body position is changed, and the device is reinserted, and if it is known from a beginning of the procedure that the lateral wall of the lumen of the hollow organ will be observed, the patient is placed in the semilateral, lateral, or semiprone position at the beginning of the procedure;
- (b) inserting the device into the lumen while rotating a holding portion of the device clockwise or counterclockwise from the perspective of a person operating the device;
- turning a tip of the device to the lateral wall of the lumen by rotating the holding portion of the device counterclockwise after inserting the device while rotating the holding portion of the device clockwise, or clockwise after inserting the device while rotating the holding portion of the device counterclockwise;
- and
- examining the lateral wall of the lumen;
- (c) inserting the device into the lumen while rotating the holding portion of the device counterclockwise by 360 degrees from the perspective of a person operating the device, wherein the device forms a loop for avoiding contact with organs, securing the visual field or securing the insertion route;
- (d) retracting an organ inside the hollow organ with the device itself by rotating the holding portion of the device counterclockwise or clockwise from the perspective of the person operating the device for securing the visual field or securing the insertion route, wherein the device is rotated counterclockwise or clockwise while the device is not pulled to prevent the effect of retraction from weakening;
- (e) retracting the organ inside the hollow organ with the device itself by pulling or pushing the device while applying an upward angle for securing the visual field or securing the insertion route, wherein the device is pulled or pushed while the device is not rotated for preventing the effect of retraction from weakening;
- and
- (f) retracting the organ inside the hollow organ with the device itself by pushing the device while applying a downward angle for securing the visual field or securing the insertion route, wherein the device is pushed while the device is not rotated for preventing the effect of retraction from weakening.

A flexible endoscope insertion method, comprising inserting a flexible endoscope having a holding portion and a tip into a body cavity, the method further comprising:
- (a) rotating a body cavity by 0 to 90 degrees by changing a patient's body position to a desired position for observing a lateral side of an organ in the body cavity,
- wherein if the body position must be changed during a procedure, the flexible endoscope is remain inserted, or the flexible endoscope is removed, the body position is changed, and the flexible endoscope is reinserted, and if it is known from a beginning of the procedure that the lateral side of the organ in the body cavity will be observed, the patient is placed in the desired position at the beginning of the procedure;
- (b) inserting the flexible endoscope toward the organ while rotating an insertion portion of the flexible endoscope clockwise or counterclockwise from the perspective of a person operating the flexible endoscope;
- turning a tip of the flexible endoscope to the lateral side of the organ by rotating the holding portion of the flexible endoscope counterclockwise after inserting the flexible endoscope while rotating the holding portion of the flexible endoscope clockwise, or rotating the holding portion of the flexible endoscope clockwise after inserting the flexible endoscope while rotating the holding portion of the flexible endoscope counterclockwise;
- and
- examining the lateral side of the organ;
- (c) inserting the flexible endoscope toward the organ inside the body cavity while rotating the insertion portion of the flexible endoscope counterclockwise by 360 degrees from the perspective of a person operating the flexible endoscope, wherein the flexible endoscope forms a loop for avoiding contact with organs, securing the visual field or securing the insertion route;
- (d) retracting an organ inside the body cavity with the flexible endoscope itself by rotating the insertion portion of the flexible endoscope counterclockwise or clockwise from the perspective of the person operating the endoscope for securing the visual field or securing the insertion route, wherein the flexible endoscope is rotated counterclockwise or clockwise while the flexible endoscope is not pulled to prevent the effect of retraction from weakening;
- (e) retracting an organ inside the body cavity with the flexible endoscope itself by pulling or pushing the flexible endoscope while applying an upward angle for securing the visual field or securing the insertion route, wherein the flexible endoscope is pulled or pushed while the flexible endoscope is not rotated to prevent the effect of retraction from weakening;
- and
- (f) retracting an organ inside the body cavity with the flexible endoscope itself by pushing the flexible endoscope while applying a downward angle for securing the visual field or securing the insertion route, wherein the flexible endoscope is pushed while the flexible endoscope is not rotated to prevent the effect of retraction from weakening.
