- 摘要：
PROBLEM TO BE SOLVED: To improve the maneuverability in a pericardioscopic procedure while suppressing complications such as cardiac tamponade, by ensuring a space necessary for operation of an endoscope or surgical instrument without providing the endoscope or surgical instrument with special space ensuring means and without unnecessarily dilating a pericardial space.
SOLUTION: A space ensuring device 1 may be deformable between a contracted state in which the space ensuring device can be accommodated inside a guide tube 8 that is inserted into the pericardial space C and an expanded state in which the space ensuring device is released out of the guide tube 8 and is thereby expanded. The device is formed of an elastic material that generates the resilient force enabling expansion against a pressure applied by a pericardium B and a heart A, and has a shape in the expanded state to ensure a space 7 inside which is opened to the surface of the heart A and can be entered from outside.
