Abstract

The present invention is directed to an endoscopic surgery apparatus for performing treating operation in a body cavity of a patient with the use of treating tools in combination with an endoscope, in which insertion sections allowing the insertion of treating tools are externally arranged in a side-by-side fashion with an insertion section of the endoscope set between these insertion sections and a balloon is provided near a distal end of the insertion section of the endoscope to adjust a relative distance between the insertion sections relative to the insertion section of the endoscope. The balloon is provided on the insertion section of the endoscope and, when the endoscope and treating tools are introduced into the body cavity of the patient, it is possible to easily and properly lead the endoscope and treating tools to a region of interest of the patient.

Dependent claims

An endoscopic surgery apparatus for performing treating operation in a body cavity of a patient, comprising:

an endoscope having an insertion section with at least an observation device incorporated therein;
at least first and second treating tools each having an insertion section and each being operable in combination with the endoscope;
a distance adjusting device for adjusting a relative distance between at least one pair of the observation device of the endoscope, insertion section of the first treating tool and insertion section of the second treating tool in a direction substantially orthogonal with an axial direction of the insertion section of the endoscope;
and
an operating device for remotely operating the distance adjusting device;
wherein the distance adjusting device comprises a treating tool raising device arranged at a distal end portion of the insertion portion of the endoscope for raising one of the treating tools in a direction away from the insertion section of the other one of the first and second treating tools and different from the axial direction of the insertion section of the endoscope.
