Claim 0:
1. A confocal endoscope with a fixing device, comprising:
an insertion tube;
a flexible tube, slidably sleeved outside the insertion tube, wherein a plurality of containing units are formed in an outer wall of the flexible tube in an axial direction and are distributed in the axial direction of the flexible tube at intervals, each containing unit comprises a plurality of containing grooves evenly distributed in a circumferential direction of the flexible tube, and the outer wall of the flexible tube is concaved inwards to form the containing grooves;
a plurality of airbag assemblies, wherein the airbag assemblies and the containing units are arranged in a one-to-one correspondence mode, each airbag assembly comprises a plurality of elastic airbags, the elastic airbags and the containing grooves are arranged in a one-to-one correspondence mode, and the elastic airbags are connected to inner walls of the containing grooves; and
a pressure supply assembly, selectively communicated with the elastic airbags of one or more airbag assemblies and configured to inject fluid media into the elastic airbags, wherein the elastic airbags are bulged to limit the flexible tube and restrain the insertion tube;
wherein
a plurality of fixing holes are formed on the flexible tube and are arranged in the axial direction of the flexible tube;
inner walls of the containing grooves are concaved inwards to form first communicating holes;
the first communicating holes are communicated with the fixing holes, and the elastic airbags are communicated with the first communicating holes;
the pressure supply assembly comprises a plurality of conveying elements and pressure supply elements;
the conveying elements and the fixing holes are arranged in a one-to-one correspondence mode;
each conveying element comprises a conveying tube and a sealing portion;
the conveying tube is slidably inserted in the fixing hole and is sealedly connected to an inner wall of the fixing hole;
second communicating holes opposite to the first communicating holes are formed on the conveying tube;
the second communicating holes and the first communicating holes are arranged in a one-to-one correspondence mode;
the sealing portion selectively seals some of the second communicating holes; and
the pressure supply element is communicated with each conveying tube and configured to inject fluid media into the conveying tube.
