Abstract

There is provided an endoscopic inserting system. The system includes an endoscope which is inserted into a lumen inside a body through a natural opening of a human body, an opening member which forms an opening for inserting the endoscope into a thoracic cavity or an abdominal cavity from the lumen inside the body at a wall portion of the lumen, and a retracting member which, when forming the opening, retracts the wall portion of the lumen.

Claims

1. An endoscopic inserting system comprising:

an endoscope which is inserted into a lumen inside a body through a natural opening of a human body;

an opening member which forms an opening for inserting the endoscope into a thoracic cavity or an abdominal cavity from the lumen inside the body at a wall portion of the lumen; and

a retracting member which, when forming the opening, retracts the wall portion of the lumen.

2. An endoscopic inserting system according to claim 1, further comprising an introducer into which the endoscope is capable of being inserted.

3. An endoscopic inserting system according to claim 2, wherein the retracting member is provided at the introducer.

4. An endoscopic inserting system according to claim 1, wherein the retracting member comprises:

a sucker which provides a negative pressure; and

a tubular member to maintain a negative pressure at a region in which the opening member acts.

5. An endoscopic inserting system according to claim 4, wherein the tubular member is a hood which is removable at a distal end of the endoscope.

6. An endoscopic inserting system according to claim 4, wherein the tubular member is an over-tube through which the endoscope is capable of being inserted.

7. An endoscopic inserting system according to claim 1, wherein the retracting member has a gripping member by which the wall portion of the lumen is capable of being gripped.

8. An endoscopic inserting system according to claim 7, wherein the endoscope comprises:

a tubular member which has a distal end portion, through which the gripping member is capable of being inserted, and which has a distal end; and

a tubular member mounted at a distal end portion of the endoscope, and the gripping member is inserted into the tubular member.

9. An endoscopic inserting system according to claim 7, wherein the tubular member is an over-tube through which the endoscope is capable of being inserted and at which a channel is provided, and the gripping member is capable of being inserted into the channel.

10. An endoscopic inserting system comprising:

an endoscope which is capable of being inserted into a lumen inside a body through a natural opening of a human body;

an over-tube through which the endoscope is capable of being inserted; and

an introducer into which the endoscope inserted through the over-tube is capable of being inserted.

11. An endoscopic inserting system according to claim 10, further comprising:

an opening member which forms an opening for inserting the endoscope into a thoracic cavity or an abdominal cavity through a lumen inside a body at a wall portion of the lumen; and

a retracting member which, when forming the opening, retracts a lumen wall.

12. A balloon dilator comprising:

a distal end portion;

a center portion;

a proximal end portion;

a distal maximum external diameter portion disposed at a distal side more than the center portion, the distal maximum external diameter portion having a diameter which is greater than the center portion;

a proximal maximum external diameter portion disposed at a proximal side more than the center portion, the proximal maximum external diameter portion having a diameter which is greater than the center portion;

a surface portion; and

a marker provided at the surface portion.

13. A balloon dilator according to claim 12, wherein the marker is an X-ray marker.

14. A balloon dilator according to claim 12, wherein the balloon dilator has a lumen through which a guide wire is inserted.

15. A balloon dilator according to claim 12, wherein the balloon dilator has a high-frequency surgical knife disposed at the distal end portion.

16. A balloon dilator according to claim 15, wherein the high-frequency surgical knife is formed in a needle shape.

17. A balloon dilator according to claim 15, wherein the high-frequency surgical knife can be removed, and a guide wire can be inserted therethrough.

18. A balloon dilator according to claim 16, wherein the high-frequency surgical knife can be removed, a guide wire can be inserted therethrough.

19. A balloon dilator according to claim 12, wherein the marker indicates at least one of the distal maximum diameter portion, center portion, and proximal maximum diameter portion.
