first, according to the normal intestinal dimensions of both ends of the lesion position, the first and second connecting ribs 272 and 662 with proper lengths are respectively replaced, so as to control the expansion diameters of the first and second umbrella-shaped mechanisms 2 and 6. The tissue reduction support device is in a contracted state in an initial state, and when the tissue reduction support device is used, the device in the contracted state is transported to a lesion position from the anus of a patient, so that the umbrella-shaped mechanism I2 and the umbrella-shaped mechanism II 6 are respectively positioned at two sides of the intussusception part of the patient; the umbrella-shaped mechanism I2 and the umbrella-shaped mechanism II 6 are expanded and then generate friction force with the wall surface of the normal intestinal canal so as to be fixed with the intestinal canal wall, the main knob 11 is used for controlling the length of the telescopic bag pipe 4, the telescopic bag pipe 4 is inflated and stretched by inflating the air inlet pipe 7, and the generated force drives the intestinal canal at the two ends of the umbrella-shaped mechanism I2 and the umbrella-shaped mechanism II 6 to respectively move in opposite directions, so that the therapeutic effect of resetting the intussusception part is achieved.
When the device is withdrawn, the first umbrella mechanism 2 and the second umbrella mechanism 6 are returned to the contracted state through corresponding operations, and the main knob 11 is rotated to shorten the paying-out length of the drawstring 41 so as to contract the telescopic bag tube 4 and withdraw the telescopic bag tube from the body.
The first supporting rib 27 and the second supporting rib 66 which are designed in a sectional mode can control the size of the umbrella-shaped mechanism in the expanding state by replacing the connecting frameworks with different lengths, so that the umbrella-shaped mechanism is suitable for the use requirements of patients with different intestinal sizes and the operation requirements of intussusception parts with different diameters, the umbrella ribs with better flexibility can be well adapted to intestinal tracts with different shapes, and the risk of injuries caused by the contact of the umbrella ribs with the intestinal tracts in the treatment process can be reduced. But also can treat intussusception of varying intussusception degrees by adjusting the length of bellows tube 4, and control inflation pressure by controlling the length of bellows tube 4.
The foregoing has outlined and described the basic principles, features, and advantages of the present invention. However, the foregoing is merely specific examples of the present invention, and the technical features of the present invention are not limited thereto, and any other embodiments that are derived by those skilled in the art without departing from the technical solution of the present invention are included in the scope of the present invention.
