Endoscopic surgery device
First Claim
1. An endoscopic surgery device comprising:
- a guide member configured to penetrate through a body wall to be inserted into a body cavity;
an endoscope insertion path which is provided inside the guide member, and into which an endoscope configured to observe an inside of the body cavity is inserted in a back-and-forth movable manner;
a treatment tool insertion path which is provided inside the guide member, and into which a treatment tool configured to inspect or treat a diseased part in the body cavity is inserted in a back-and-forth movable manner;
a position sensor configured to detect a movement amount of the treatment tool with respect to the guide member when the treatment tool inserted into the treatment tool insertion path moves back and forth; and
an image capture controller, wherein a range of an observation image acquired by the endoscope is not changed if the movement amount of the treatment tool is within a predetermined range when the movement amount of the treatment tool is detected by the position sensor, and the range of the observation image is changed in accordance with the movement amount of the treatment tool if the movement amount of the treatment tool is not within the predetermined range,wherein outside the predetermined range, a ratio of a movement amount of the endoscope to the movement amount of the treatment tool is equal to one.
