<P>PROBLEM TO BE SOLVED: To provide an insertion assisting tool to smoothly facilitate an inserting function of an insertion part of an inserter in and out of internal organs. <P>SOLUTION: An insertion assisting tool body is equipped with a connector 128, a seal member 124 and an air conduit tube 130. The connector 128 is capable of connecting an insertion duct 8 which communicates with internal organs and outside the body for examination, by the edge of the insertion duct 8 from outside the body for examination. A through-hole 122 communicates with the insertion duct 8 through the connector 128 and has a diameter greater than the outer diameter of an insertion part 22a of an inserter 22 to facilitate the sealing by the sealing member 124 between the through-hole 122 and an atmosphere within the internal organs through the insertion duct 8, to receive the insertion part 22a within the through-hole 122. One end of the air conduit tube 130 communicates with the through-hole 122, and the air conduit tube 130 is away from the through-hole 122 between the connector 128 and the seal member 124. The device is further equipped with an air feeding pump 136 and a pressure controlling valve 134. The air feeding pump 136 feeds air to the air conduit tube 130. The pressure controlling valve 134 is provided between the air feeding pump 136 and the air conduit tube 130 and is equipped with an actuation controlling mechanism to detect the pressure within the internal organs and control the actuation of the air feeding pump 136. <P>COPYRIGHT: (C)2003,JPO |
