specific Embodiment approach 1
[0037] An inflatable visualized gastric tube traction device according to this embodiment, such as Figure 1-3 As shown, the inflatable visualized gastric tube traction device includes an endoscope 1, a combined guiding air bag 2, an air bag band 3, a sealing plug 4, a cannula 5, a gastrointestinal tube 6 and a set of inflatable tubes 7. Mirror 1, combined guide air bag 2, sealing plug 4, sleeve tube 5, and gastrointestinal tube 6 are arranged concentrically;
[0038] The airbag belt 3 is arranged according to the extension direction of the traction device and is set on the outer wall of the combined guide airbag 2. The shape of the combined guide airbag 2 is cylindrical, and the rear end of the combined guide airbag 2 is fixedly connected to one end of the sealing plug 4. , the other end of the sealing plug 4 fits the front end of the sleeve 5, and the outer wall of the sleeve 5 fits the gastrointestinal tube 6; the endoscope 1 passes through the gastrointestinal tube 6, the ...
specific Embodiment approach 2
[0040] The difference from Embodiment 1 is that an inflatable visualized gastric tube traction device in this embodiment, such as Figure 4 As shown, the middle part of the sealing plug 4 is provided with a sealing plug middle hole 4a, so that the endoscope 1 passes through and is installed through the sealing plug middle hole 4a; the outer ring of the sealing plug middle hole 4a is evenly distributed A set of sealed lockperipheral holes 4b, so that the inflation tube 7 can pass and be installed therethrough.
[0041] There are 3-6 sealed lock holes 4b.
specific Embodiment approach 3
[0043] The difference from Embodiment 1 or Embodiment 2 is that an inflatable visualized gastric tube traction device in this embodiment, such as Figure 5 , 6 As shown, the combined guide airbag 2 includes a group of airbag modules 2a, and a group of airbag modules 2a are arranged in a circle with the central axis of the endoscope 1 as the central axis. The central axes are parallel, and each airbag module 2a is a strip-shaped hollow structure. The end of the airbag module 2a is provided with an inflation hole 2a2, and the outer wall of the airbag module 2a is arranged with a set of belt grooves 2a1 at equal intervals along the length direction. An inner groove 2a3 is provided on the inner side wall of the module 2a, and the extension direction of the inner groove 2a3 is consistent with the length direction of the airbag module 2a;
[0044] The belt groove 2a1 is used to install and fix the airbag belt 3, and the combined guide airbag 2 is fixed by means of the airbag belt 3...
